SOC 2 Type II: Why Operational Control Matters When Risk Is the Job

Replica Achieves SOC 2 Type II Certification.

Customers trust Replica with their most sensitive work. They use the platform for investigations, security operations, tool evaluation, collaboration, and other workflows where confidentiality, control, and clear oversight can’t be compromised.

SOC 2 Type II reflects an independent, 90-day audit of the controls that support how Replica operates and protects customer data. The certification focused on change and configuration management: validating that updates, access, and system changes are governed, logged, and controlled consistently. For customers, it adds independent assurance during vendor review and gives them confidence in the systems backing the platform.

The Containment Model

Most security companies focus on keeping risky things out of their boundary. Replica does the opposite.

Replica was built for the work most companies are afraid of. Investigations. Threat operations. Strategic research. Sensitive collaboration. AI experimentation. That work doesn’t go away because it’s risky, it just moves somewhere even more unsafe. We help you do it right.

That’s why change and configuration management matter more for Replica than for most platforms. Every update, every access change, every system configuration shift has to be controlled, audited, and traceable. Not to prevent the risky work, but to contain it and ensure nothing moves beyond the boundary without intent and visibility.

SOC 2 Type II validates that this control model works accurately, in the real world, over time.

Start With Trust

Long before deployment, trust shows up early in security questionnaires, procurement reviews, legal review, and internal risk conversations. Customers want to know how a vendor handles customer data, how the service is run, and whether the company behind the platform operates with consistency and care.

SOC 2 Type II helps answer those questions through a framework many organizations already know how to evaluate. It gives customers a clearer picture of the controls behind the service and adds independent validation to the trust Replica works to earn every day.

Support the Review Process

For many organizations, buying a security product involves more than validating features. It also means moving through internal review with the right level of confidence and documentation.

SOC 2 Type II helps make that process smoother. Security teams want evidence. Procurement teams want fewer surprises. Legal and compliance stakeholders want a clearer understanding of how a vendor operates and how customer data is protected.

Having a SOC 2 Type II report does not remove every step in that process, but it gives customers a familiar starting point and helps move the conversation forward with less ambiguity.

What SOC 2 Type II Delivers

While SOC 2 Type II validates operational controls and data protection practices, it’s not a feature audit or a penetration test. You get a window into how the company operates, how changes are managed, and how controls perform over time.

For Replica, that’s exactly what matters. If you’re using the platform for sensitive work at the edge of acceptable risk, you need to know the company behind it has tight operational discipline. You need to know that changes are controlled, access is governed, and nothing slips out without being tracked. That’s what our certification validates.

What’s Next

SOC 2 Type II is one milestone in a larger commitment to operational rigor and compliance. Replica is already in progress on HIPAA Business Associate certification, reflecting continued investment in the controls and operating discipline that support customers in regulated environments.

The bar keeps rising. Customers expect strong security from the companies they trust, especially when the work involves confidential data, regulated environments, or elevated risk. This certification reflects that commitment, and it won’t be the last one.

The burring of AI Security, a graphic showing that different tactics are converging into one

The New Vocabulary of AI Security

Why access, visibility, confidentiality, and agent control are being collapsed into one blurry category.

AI security means too many things at once. In one conversation, it means model safety. In another, prompt leakage. Then it’s agent permissions, policy controls, whether sensitive work can happen without revealing too much through traffic and metadata.

These problems show up in different places and require different solutions. But they’re being talked about as if they’re the same thing. The market is starting to group them together under the same umbrella. Terms like agentic AI, AI visibility, confidential AI, and agent security are showing up everywhere. The language is moving quickly.

The Vocabulary Problem 

Security leaders hear “AI security” and think one category should cover it all: governance, confidentiality, visibility, agent permissions, workflow control. So, teams end up comparing policy products to visibility products. They treat observability like containment. They assume protecting prompts also protects the workflow. They ask whether an agent is allowed but never consider where that agent should be operating in the first place.

That is why this feels like a vocabulary problem before it becomes anything else.

Here are three distinctions that are especially important right now:

  1. Access vs. visibility. Access controls who can reach a model or agent. Visibility is what you can see while it’s being used: prompts, destinations, timing, metadata, what the agent does. You can have strong access controls and no idea what happens once usage starts. The reverse is also true. Both matter. They solve different problems.
  2. Confidentiality vs. context leakage. Confidentiality protects the contents of prompts, files, and outputs. Context leakage is the information exposed by the activity around the work: what’s being researched, when usage spikes, which systems are involved, how work is moving. Protected content doesn’t mean protected context. Behavior itself can be revealing.
  3. Governance vs. agent security. Governance is policy: who can use which tools, with what data, under what rules. Agent security is what happens once that agent is connected to systems: what it can retrieve, call, trigger, expose, or automate. Approving the use of a tool is different from understanding what it does when it starts acting inside your workflow.

Fuzziness Creates Friction

Category confusion = procurement confusion. This leads to confusion in how teams evaluate and buy. And that usually means one of two things: either teams buy something that solves only part of the problem, or they delay decisions because the category itself feels impossible to compare cleanly.

The vocabulary matters because it shapes what teams build, how they work safely, and ROI. Here’s how we think about it:

  • AI access: Who or what can reach an AI model, tool, connector, or agent.
  • AI visibility: What can be observed about AI use while work is happening, including actions, destinations, timing, metadata, and workflow behavior.
  • AI exposure: What sensitive information is revealed through the use of AI, not just through the final output.
  • Agent security: Controls on what AI agents can access, retrieve, call, trigger, or automate once connected.
  • Confidential AI: Protection for sensitive AI data and computation while in use.
  • Context leakage: Exposure created by traffic, metadata, timing, behavioral patterns, and surrounding workflow signals.
  • Governed AI workflow: A policy-defined AI workflow with clear rules, auditability, and operational boundaries.
  • Isolated AI workflow: A contained environment for evaluating or using AI tools, models, or agents without exposing corporate endpoints, production systems, or more context than necessary. Can you isolate the work? Can you see what’s happening? Who can access it? What leaves the environment? What’s the agent authorized to do?

That last category may matter more than you think. Especially for the kinds of use cases that are hardest to approve internally: evaluating new AI tools, testing agents against sensitive workflows, investigating risky sources, or enabling experimentation that would otherwise create too much exposure.

The market does not need more AI-security language for its own sake, but it needs clearer definitions. For internal teams, they make gaps easier to see, policy exceptions easier to judge, and the resulting architecture more purpose-built from the start.

Why access, visibility, confidentiality, and agent control are being collapsed into one blurry category. It's time for a new vocabulary...

A man torn between data security and allowing employees to bring their own device

The BYOD Contradiction

Your BYOD policy says the device is the employee’s problem. Your security program says the data is yours. At some point, someone must reconcile those two things. Most organizations haven’t.  They wrote a policy, pushed an MDM profile, and moved on. The access problem was solved. The data problem got deferred. And deferred problems have a way of surfacing at the worst possible moment: in a compliance review, during an audit, or when someone in a board meeting asks what happens to sensitive data on personal devices.  Most security leaders don’t have a clean answer. They have a policy document. Those are not the same thing. 

MDM governs the device, not the work done on it 

Mobile device management was built to solve a specific problem: hardware at scale. It does that reasonably well. It can enforce a passcode, push a configuration, restrict an app, or wipe a device when something goes wrong.  What it cannot do is tell you what happened inside a browser session. It cannot tell you whether sensitive data was copied from a SaaS application into a personal notes app, whether a regulated document got downloaded “just for a minute,” or what an AI tool retained from a file uploaded during a work task. It cannot produce an audit trail of actions taken inside applications that live outside corporate infrastructure.  In a workplace where most work happens through a browser (SaaS platforms, collaboration tools, AI assistants, internal portals), the device is only a fraction of the actual exposure surface. Governing the hardware is not the same as governing the work. Most BYOD programs haven’t closed that gap.

Most BYOD programs are solving the wrong problem 

What if… Organizations stopped trying to manage devices?  What if the sensitive work never ran on the device at all?  When sensitive tasks happen inside a controlled, isolated environment, the device on the other end becomes mostly irrelevant. It can be personal, unmanaged, out of date, sitting on an unknown network. The data never landed on it; the session ended and left nothing behind.  That is what it actually looks like to resolve the contradiction, rather than manage around it. And it is the answer that holds up when the auditor asks. 

Three examples 

Employee on a personal laptop doing regulated work 

Before: Sensitive workflows run on a device the organization doesn’t control and can’t fully audit. MDM provides guardrails but not visibility into what happened inside the session. If a compliance question comes up, the answer involves a lot of assumptions.  After: The regulated workflow runs in an isolated environment. The personal laptop is a display and input surface, nothing more. No data lands on the device. The session is auditable from start to finish. 

Hybrid worker accessing sensitive SaaS from a home machine 

Before: An MDM profile and a VPN connection sit between a personal device and corporate applications. The organization has limited visibility into what happens inside those applications, what gets downloaded, what gets copied, or where it ends up.  After: Access to sensitive SaaS runs through a governed session. Copy, paste, download, and upload behaviors are controlled at the environment level. The home machine never becomes the place where organizational data lives, even temporarily. 

Executive traveling on a personal device 

Before: An exception process, a VPN, and the assumption that a senior leader will exercise good judgment. None of that produces an audit trail. None of it prevents data from sitting on a device that crosses borders, connects to unfamiliar networks, or gets lost in a hotel.  After: Full access from any device, any location, with nothing sensitive left on the endpoint. The session closes, the environment is gone, and what happened inside it is logged. 

The BYOD conversation generates a lot of feature comparisons. Before getting into specifics, four questions help get right to the point: 

  1. Does sensitive data land on the local device? Not “is it encrypted in transit” or “is access controlled at login.” Does the data actually reside on the endpoint at any point during or after the session? If the answer is yes, the device is still in your threat model regardless of what else the solution does. 
  2. Can you produce a full audit trail without examining the endpoint? If answering a compliance question requires pulling the personal device, you’ve already lost. The session record should exist independently of whatever is on the hardware. 
  3. Does it work from any device without enrollment, agents, or a corporate build? A solution that requires managing the personal device to protect work running on it has not resolved the contradiction. It has relocated the management problem. 
  4. Does it create enough friction that people find workarounds? Security controls that are too heavy will get bypassed. If working in a governed environment is significantly worse than the unmanaged alternative, the policy holds on paper and fails in practice.
 
  MDM-based BYOD  Isolated environment 
Data on the endpoint after session  Yes  No 
Audit trail without device forensics  Rarely  Always 
Works from unmanaged devices without enrollment  No  Yes 
Friction that drives workarounds  High  Low 

Bottom line 

BYOD was always a data problem. The device framing made it feel manageable — whose hardware, whose responsibility, whose MDM profile. But the actual question was always simpler and harder: whose data is this, where does it live, and what happens when the session ends? 

Most BYOD programs answered the first question and left the other two open. The ones that have closed them stopped trying to govern the hardware and started governing the environment where the work runs. The device stays personal. The work stays controlled. When those two things stop competing, the compliance answer gets a lot cleaner. 

See how Replica keeps sensitive work contained regardless of what device is on the other end.

Your BYOD policy says the device is the employee's problem. Your security program says the data is yours. How do...

two times cyber defense magazine award winner

Replica Cyber Named Double Winner in Cyber Defense Magazine's 14th Annual Global InfoSec Awards at RSA Conference 2026

Company recognized as Market Disruptor Security Investigation Platform and Most Promising Secure Enclaves

SAN FRANCISCO, March 23, 2026 — Most security teams have worked around the same problem for years: the highest-stakes work still happens in the least controlled environments. An analyst pivoting through criminal infrastructure on a personal laptop. Malware analysis running in a lab VM. A new AI tool being tested against real case data with no governance. Replica Cyber was built to give that work a proper home, and today the industry is taking notice.

Replica Cyber , the secure environments platform for high-stakes work, has been named a double winner in Cyber Defense Magazine’s 14th Annual Global InfoSec Awards, recognized as Market Disruptor – Security Investigation Platform and Most Promising – Secure Enclaves . The awards are presented annually at RSAC, the largest and most influential cybersecurity conference in the world.

Replica will be on site during RSAC week in San Francisco. On Monday, March 23, the team will participate in the Cyber Startup Expo at Convene 100 Stockton. On Tuesday, March 24, Replica will host a Partners Day at the Marriott Marquis.

“The work security teams need to do has outpaced the environments they have to do it in. Investigations, AI experimentation, fraud analysis, these are high-stakes operations that deserve purpose-built infrastructure, not workarounds. That is the precise problem Replica solves, and it is gratifying to see that recognized by Cyber Defense Magazine.”

— Kristopher Schroeder, Founder and CEO, Replica Cyber

Market Disruptor — Security Investigation Platform

Security investigation is among the highest stakes work any organization runs, and for most teams it happens in environments that were never designed for it. Replica provides fully isolated workspaces where analysts can detonate malware, pivot across criminal infrastructure and dark web markets, run OSINT and closed-source tools at scale, and test new GenAI workflows against real case data, all off the corporate network, under full logging and policy control. Investigation environments are templated for specific workflows including ransomware cases, business email compromise, and dark web fraud operations, and can be stood up in minutes with the right tools and protections already in place. Security leaders get complete visibility and evidence chains without slowing analysts down.

Most Promising — Secure Enclaves

Replica takes the secure enclave from architectural concept to operational practice. Rather than a one-off hardened server or a network segment only a handful of people can access, Replica gives organizations on-demand, repeatable, mission-tailored environments, each isolated from corporate networks and unmanaged devices, each designed around zero-trust, least-privilege, and evidence-ready principles. A dark web research enclave looks different from an AI experimentation workspace or an M&A due diligence environment, but all of them follow the same governance model: centralized policy, full logging, and audit-ready chain of custody. High-stakes work finally has a home that meets the bar security requires and moves at the speed the business demands.

“Replica Cyber identified a gap that most of the industry had accepted as a cost of doing business — that the riskiest security work has nowhere safe to happen. Their approach to governed, isolated environments for investigation and high-stakes operations addresses one of the most persistent blind spots in enterprise security. That is exactly the kind of thinking our Global InfoSec Awards exist to recognize.”

— Gary S. Miliefsky, Publisher, Cyber Defense Magazine

three time Globee award winners

Replica Cyber Wins Three 2026 Globee Awards for Cybersecurity

Recognized for Security Investigation, Browser Isolation, and Most Innovative Next Generation Security

MCLEAN, Va., March 19, 2026 — Replica Cyber today announced it has been named a winner in three categories in the 2026 Globee Awards for Cybersecurity: Security Investigation, Browser Isolation, and Most Innovative Next Generation Security. The Globee Awards are a global recognition program honoring achievement across the cybersecurity industry, evaluated by experienced professionals and industry experts worldwide. Security teams continue to do more consequential work with less margin for error, and the environments they operate in have not kept pace. Investigations, dark web browsing, AI experimentation, sensitive collaboration: each is done in the available general-purpose infrastructure, controlled after the fact by policies layered on top. Replica starts from a different position: the environment where high-stakes work happens is the control, and these three awards each recognize a different dimension of that approach.

Security Investigation — Best of Category

Replica provides purpose-built secure environments that spin up immediately with the pre-built templates already configured for the work at hand. Every action is tied to identity, governed by policy, and logged automatically, giving investigators the ability to go deeper on cases they would otherwise avoid and giving security leaders defensible evidence trails when the work concludes. Replica secures the organization, the investigator and the mission. 

Browser Isolation — Best of Category

Replica isolates the entire environment where browsing happens, not just the browser tabs. Analysts and automated processes get a complete workspace with its own identity, egress, and data-handling rules, running at full fidelity on the complex sites and dark web platforms where many browser isolation tools break down. Most tools in this category isolate a single browser session. Learn how Replica isolates any browser, any workflow, any tool, inside a governed environment built for the work.

Most Innovative Next Generation Security — Best of Category

Replica gives security, IT, and risk teams auditable environments for work that carries major organizational risk, such as incident investigations, AI pilots, sensitive transactions, third-party collaboration. Each can be isolated from production, tied to identity and policy, persistent while needed, and disposable when the work concludes. The innovation is a practical answer to where high-stakes work should live, not a new detection layer on the same fragile infrastructure. 

“Winning in browser isolation was particularly meaningful. Most tools in that category isolate a single browser session. When you contain the work itself rather than just the window it happens in, you get real protection. These three awards together point to where the market is heading, and we are enthused the industry is recognizing the shift.” — Kristopher Schroeder, Co- Founder and CEO, Replica Cyber

“Congratulations to the 2026 winners for their exceptional contributions to strengthening our digital world. Your innovation, dedication, and leadership continue to advance cybersecurity and inspire progress across industries. We are proud to recognize and celebrate your success.” — San Madan, President, Globee Awards

What Happens After Login? How to Protect High-Stakes Work When the Session Becomes the Risk.

Security teams have spent years fortifying the entrance. Strong passwords, MFA, SSO, conditional access, device posture checks. Those controls have done important work. They have made opportunistic account compromise harder and raised the cost of credential theft. Yet they have also encouraged a habit of thought that no longer fits the shape of modern risk. Once the user is authenticated, the decisive moment has passed. The door is secure. The rest is administration… or is it? That confidence is harder to sustain now. 

Across recent guidance from Microsoft, Google Cloud, and CISA, the same concern keeps resurfacing in different forms: token theft, session replay, browser-in-the-middle attacks, and post-authentication abuse all show how much danger can gather after access has already been granted. Microsoft’s guidance on token theft focuses on how attackers exploit live tokens and authenticated sessions. Google has highlighted session-cookie theft and device-bound session protections. CISA continues to track attacker use of alternate authentication material that can bypass the protections organizations associate with the login event itself.  

For organizations responsible for sensitive research, suspicious content analysis, software validation, external collaboration, or AI evaluation, that shift has real-world consequences. We used to only worry about who got in. Now, we need to extend that level of caution to what unfolds once the session is alive. 

Inside the front door 

Identity became the center of enterprise security for sensible reasons. If attackers were stealing passwords and reusing credentials, stronger authentication was the clearest answer. The industry invested heavily there, and much of that investment paid off. It still matters but isn’t enough. 

Microsoft’s token theft playbook makes the limitation plain. A user can authenticate successfully and still lose control of the session through stolen or replayed tokens. Google has described how infostealers and browser-in-the-middle techniques can undermine the protection people assume MFA provides, especially when session material is exposed and reused elsewhere. In other words, identity can be proven while the session itself remains vulnerable.  

Risk taking up residence 

Work no longer arrives in the neat format which enterprise architecture once preferred. It moves through browsers and SaaS applications, collaboration tools, AI interfaces, vendor trials, research portals, developer sandboxes, and unfamiliar web properties. Sessions last longer. Context shifts faster. Approved tools sit beside provisional ones. Users move between environments carrying data, assumptions of trust, and unfinished judgments with them. Under those conditions, the live session begins to matter just as much as the login event that created it. 

That is why recent guidance has shifted toward layered protections for tokens, device binding, risk-based controls, and better detection of post-authentication abuse. The concern is not theoretical. Microsoft documents token replay as a real attack path. Google’s security teams have written about session stealing and the need to reduce the value of stolen cookies. CISA has likewise warned that attackers use alternate authentication material to gain access without needing the original password.  

Valid access, then, can still produce dangerous conditions. The user may be legitimate. The task may be legitimate. The exposure appears in the interaction itself: the unknown file, the external platform, the copied text, the uploaded document, the test account created in haste, the prompt entered into a tool whose boundaries are still uncertain. 

Exposure, within legitimate work 

The clearest examples tend to come from work that is both necessary and difficult to sanitize in advance. 

  • A threat analyst must open suspicious links, inspect malicious infrastructure, and handle material that should never touch an ordinary endpoint. 
  • A procurement or engineering team may need to evaluate a new vendor by creating an account, uploading sample data, and testing integrations before formal approval exists. 
  • An intelligence team may conduct external research where exposure and attribution have consequences of their own. 
  • A business unit experimenting with AI tools may be acting with full authorization and good intent, yet still create uncertainty around prompt handling, file retention, and the movement of sensitive information into external services. 

None of this begins with an invalid login. The trouble emerges in the ordinary unfolding of work. 

High-stakes cyber work often requires interaction with suspicious content, third-party software, untrusted research surfaces, and emerging AI tools. The work cannot simply be forbidden, because the business still needs answers, decisions, and progress. It has to happen somewhere. The question is where, and under what conditions.  

Beyond the narrow frame of browser protection 

Browser controls remain valuable, and better session telemetry is plainly useful. Security leaders do need to understand what happened during a session, what data moved, and which actions should have triggered concern. Yet a more consequential issue sits beneath that operational visibility. Where is the risky work actually taking place, and how much trust is being placed in the endpoint while it happens? 

This is where many organizations are beginning to widen the frame. They are not only looking for safer browsing. They are looking for a secure setting for consequential work, one that can contain uncertainty without bringing ordinary business motion to a halt. 

The direction of broader industry guidance points the same way. Microsoft recommends layered defenses against token theft and replay, including hardening, detection, and mitigation. Google has emphasized device-bound credentials and limits on stolen-cookie usefulness. Those are meaningful controls, but they also reveal a larger truth: the more valuable the session becomes, the more carefully the environment surrounding it must be designed.  

A secure place for high-stakes work 

That is where isolated environments begin to matter in a fuller sense. 

An isolated environment changes the place in which the work occurs. Instead of asking the endpoint, and by extension the enterprise, to absorb the uncertainty of every unknown link, vendor trial, suspicious file, external research task, or early AI experiment, the organization can move that work into a space built for ambiguity. 

The value is not only containment, though containment matters. It is also continuity. Teams still need to investigate, test, compare, validate, and decide. A security model that responds only with friction eventually teaches the business to look for side doors. A model that offers a secure environment for risky work preserves momentum while reducing the blast radius of the task. 

This is the territory Replica is built to serve. Its approach centers on secure isolated environments for the kinds of activity that make conventional environments uneasy: suspicious content analysis, third-party software validation, external research, AI testing, and other workflows where trust is provisional and the consequences of exposure are high. The ambition is practical. Let the work proceed in conditions that better fit its risk.

After authentication, the real test begins 

The industry’s language is slowly catching up to the lived experience of security teams. Authentication remains essential, but it does not account for the full texture of exposure in modern work. Session theft, token replay, post-authentication abuse, and risky interaction with external tools all point to the same conclusion. Admission is only the beginning. Stewardship begins afterward.  

For teams engaged in sensitive research, software evaluation, suspicious content handling, or early AI exploration, the decisive question is no longer exhausted by identity. It extends into the environment, containment, visibility, and control. Once the session begins, security becomes a matter of where the work lives, what the session allows, and how much of the enterprise must share in its uncertainty. 

And that is where the difference is increasingly made.

Don't Let The Session Be The Risk

FAQ 

What does it mean to say the session has become the risk?

It means many important security problems arise after a user has successfully authenticated. Attackers may steal or replay tokens, and legitimate users may still perform risky work in environments that are poorly suited to the sensitivity of the task. Microsoft and Google both describe how session material can be abused after login.  

Why is MFA no longer enough for high-stakes workflows?

MFA remains one of the most important controls for reducing account compromise, but it proves identity at a moment in time. It does not fully govern what happens after authentication, especially when sessions are long-lived or tokens can be replayed. Microsoft’s guidance on token theft and token protection is useful here.  

Is this mainly a browser problem?

The browser is part of the story because so much work happens there, but the deeper issue is broader. Organizations are deciding where risky work should occur, how it should be contained, and what evidence and controls should follow it. Browser-in-the-middle attacks are one example of post-authentication risk, not the whole picture.  

What kinds of workflows are most affected by session risk?

The pattern appears most clearly in work involving suspicious links, untrusted files, third-party software validation, external research, and AI tool evaluation. These are workflows where the user may be authorized and the business need may be real, yet the interaction itself carries unusual uncertainty. 

What should security leaders evaluate in solutions for this problem?

They should look closely at where the work runs, whether risky interactions are separated from the endpoint, how session activity is observed and governed, what evidence is preserved for investigation, and whether legitimate users can move quickly through sensitive tasks without creating unnecessary exposure. 

How do isolated environments help without slowing people down?

They give risky work a more appropriate setting. Instead of forcing teams to choose between unsafe speed and heavy exception processes, isolated environments let investigation, testing, and validation proceed in a contained space. That reduces exposure to the endpoint and the broader enterprise while preserving business momentum. 

How is this relevant to AI use in the enterprise?

AI pilots often begin before governance is fully settled. Teams want to test tools, compare outputs, upload files, and explore real workflows. That creates uncertainty around retention, data handling, and policy. A contained environment gives organizations a way to explore those tools with greater control and less spillover risk.

Security teams have spent years fortifying the entrance. Strong passwords, MFA, SSO, conditional access, device posture checks. Those controls have...
