Insider Threat Detection That Stays Need-to-Know.
Simbian investigates every insider alert against that person's own history and assigned work. Most turn out to be routine, and the case file shows why. Real cases stay with the people you name, and every action needs approval until you decide it doesn't.

How Insider Threat Detection Works in Simbian
Simbian's insider threat detection works the alerts your tools already raise. It reads identity, endpoint, email, and SaaS together and builds one case file for the people who decide.
Baseline
A Baseline for Each Person
Each person is compared with their own history and assigned work. A data scientist's model export and a recruiter's get read differently.
HR Context From Your Feed
Your HR joiner-mover-leaver feed or project roster adds role, assignments, and departure date to every alert before anyone reads it.
Low-and-Slow Data Movement
Small exports spread over several weeks rarely trip a threshold in one console. Simbian links the related alerts across all four systems.
Investigate
Four Questions DLP Can't Answer
For every Purview match, Simbian answers who moved the file, whether they're on that project, where it went, and whether that's normal for them.
One Timeline Across Four Consoles
Sign-ins, file moves, email, and SaaS sharing tied to the same alert land in one timeline inside the case file.
Context Lake™ Memory
Context Lake keeps your processes and your team's past verdicts, and each new insider case opens with the rulings that applied last time.
Decide
Approval Gates You Control
Every action starts behind human approval. You choose which ones stop being gated, and can keep a named approver on anything touching an employee's account.
Need-to-Know Case Access
Only the people you name can open an insider case, and that list stays the same as case volume grows.
One Write-Up for HR and Legal
Every case follows one structure and logs each action with the policy behind it. HR and legal get the same write-up from any analyst.
Insider Threat Management, From SOC Alert to Restricted Case
Insider threat management splits the work. Your SOC escalates an ordinary alert with the evidence attached, and your insider risk management team keeps the restricted case.

Why Is Insider Threat Detection So Hard to Staff?
The Reality
Every Analyst You Add Is One More Person Who Knows
Insider threat detection is hard to staff because each case takes hours across four consoles, so most close without a full review. Each analyst added to clear the backlog also sees a colleague's name, usually over routine work.
Insider incidents took 67 days on average to contain, according to the Ponemon Institute's 2026 Cost of Insider Risks: Global report, sponsored by DTEX.
- Rules fire on a single download, login, or policy match
- Company-wide thresholds fit almost nobody
- HR and legal get a different write-up from each analyst

Insider Threat Detection FAQs
Insider threat detection finds harmful activity by people with legitimate access: employees, contractors, and partners, whether they acted on purpose, by mistake, or from a compromised account. Most of what it raises is normal work, because a threshold set for a whole company is wrong for most of the people it covers. Comparing each person with their own history and assigned work fixes that, and insider threat prevention starts there.
No. Simbian sits on top of the insider threat solutions you run and investigates what they raise. Microsoft Purview is the most common starting point. Simbian adds identity, project, and destination to each DLP match, then records whether it was cleared or escalated and why.
Common indicators include mass downloads, logins at odd hours, sensitive files sent to personal accounts, and access outside someone's role. None of them proves anything alone. A finance analyst exporting finance data and a colleague who resigned last week running the same export are different cases, and only context separates them. Simbian checks each indicator against the person's role and project before it calls anything a case.
In July 2024, KnowBe4 found that a new hire was a North Korean fake IT worker whose application photo was an AI-enhanced stock image, after four video interviews. Samsung employees pasted source code and a meeting recording into ChatGPT in 2023. In early 2024, an Arup employee in Hong Kong made 15 transfers totaling $25M after a video call in which deepfakes posed as the CFO and colleagues.
Not unless you decide it should. Every action starts gated, including anything touching an employee, and you choose which ones ever stop being gated. Simbian adds no new sensors, and responses follow your escalation path with HR and legal.
An insider threat program depends on a small circle, and Simbian keeps it small by doing the cross-system reading that would otherwise pull in more analysts. Case access stops at the people you choose, such as your insider risk management team, and a small circle protects the employee as well as the investigation.

Security is a domain of ever-increasing complexity. Every day a security incident brings new variables. Simbian is building a fully autonomous security platform. We are excited to partner with them as it allows us to be strategic in our security goals, leaving mechanics of security to Simbian.

Sergey Gorbunov
Co-founder
Security partners, especially MSSPs and MDRs, are at a critical juncture. Attacks are getting accelerated with AI. We must use AI on defense side too. We have gotten great support from Simbian with its fully autonomous security. It allows us to do more with less, directly impacting both our top and bottom lines.

CEO
Simbian's platform takes a straightforward approach to solving core problems we see every day in the SOC. The power in the platform, their AI agents, is in its simplicity. They are not adding steps and processes to achieve results. The Security Accelerator platform drives efficiency without sacrificing efficacy. It allows us to shift the role of the analyst; to give them the time to use human insight, because well trained AI that we can review, and audit, is immensely powerful. It sets a whole new bar for security operations.

What Simbian's doing in that space has really been a differentiator and a game changer for how my team's thinking about these problems. We're no longer thinking about a pipeline of work that we've got to have 20 people to solve.
