Stop trusted access from becoming uncontrolled privilege
Employees, contractors, service accounts, API keys, machine credentials, and AI agents all operate with trusted access. Attackers and insiders exploit that trust to move through systems, reach sensitive data, and expand control without triggering traditional access-review alarms.
Drawing on real forensic investigations, SISA helps identify where trusted access is excessive, drifting, or being abused and constrain it before access becomes impact.
Inside a real privilege-escalation attack: the forensic breakdown from the Digital Threat Report 2025
THE STAKES
The most dangerous insider may not be a person. In modern regulated environments, access is granted continuously to humans and non-humans alike and rarely revisited. That's the gap insiders and attackers-posing-as-insiders exploit.
Former-employee accounts, dormant VPN access, inherited entitlements, and orphaned credentials can remain active long after the original business need has ended.
Service accounts, API keys, machine credentials, and automation scripts often accumulate high levels of access without the ownership, rotation, review, or monitoring applied to human users.
MFA validates the login event, but stolen tokens and hijacked sessions allow attackers to operate inside an already trusted session. The access looks valid; the behaviour may not be.
As organisations introduce agentic systems with access to applications, data, and workflows, AI agents can inherit service-account-like authority without equivalent governance and behavioural monitoring.
INSIDER RISK IS A TRUSTED-ACCESS CHAIN
Insider incidents rarely begin with one excessive permission.
They emerge when identity, privilege, session, behaviour, and data-access gaps align. A user may have too much access. A service account may be unowned. A session may be hijacked. A privileged path may remain untested. Sensitive data may sit closer to that path than teams realise.
SISA helps expose that trusted-access chain who or what has access, how privilege can expand, whether it is being misused, and what sensitive assets may be affected.
How SISA contains privileged access
SISA addresses each layer where trusted access turns into exposure built on what our forensic investigations and offensive security assessments show actually happens.
Simulate privilege escalation and lateral movement
Red teaming, assumed-breach assessments, and Active Directory penetration testing walk the real escalation path our forensic teams see in live cases from a single foothold through privilege escalation and lateral movement into core systems. They expose the segmentation and privilege-sprawl gaps that let trusted access become trusted control.
See privilege being misused, not just granted
Agentic detection and response watches live system flows for the behaviors that signal insider misuse and active compromise developer-to-production access, anomalous service-account behavior, lateral movement. It closes the gap between an access event and the abuse that follows it.
Validate access controls between reviews
Continuous control validation checks that access controls are configured and holding between attestation cycles. Implementation drift and orphaned-privilege gaps surface before an insider or an intruder posing as one inherits them.
Investigate suspected insider and account misuse
Internal forensic investigation and compromise assessment surface the misused credential, the live orphaned account, or the established foothold an insider or intruder is already operating from. They find it before it reaches the systems that matter.
Know what privileged access actually exposes
Data discovery and classification maps the sensitive payment and customer data in your environment, so you know precisely what any given identity human or machine can reach. Insider risk is ultimately a data-access problem; this makes it a measurable one.
Govern privileged AI-agent access
SISA helps organisations assess and govern AI-agent access by examining what systems and data AI agents can reach, whether agent permissions match intended use, whether agent actions are monitored, whether prompts, tools, and workflows can be manipulated, and whether AI systems are covered by governance and control frameworks. This helps teams bring agentic access into the same risk, monitoring, and governance model as other privileged identities.
One view of trusted-access exposure.
Insider risk develops in the gaps between identity, privilege, session, behaviour, data, and response.
Through OneLens™, SISA One unifies these capabilities into a single, board-ready picture of trusted-access exposure surfacing human and non-human identity risk, dormant credentials, excessive privilege, suspicious sessions, behavioural anomalies, escalation paths, lateral movement, sensitive-data exposure, and unresolved remediation.

FAQs
An insider threat is the misuse of trusted access — by an employee, a contractor, a compromised account, or increasingly a non-human identity like a service account or AI agent. Most insider breaches aren't malicious employees; they're failures to constrain access that was legitimately granted and never revisited.
Non-human identities are the service accounts, API keys, machine credentials, and AI agents that systems use to talk to each other. They frequently hold admin-equivalent privilege with none of the rotation, MFA, or review applied to human accounts — which makes them a preferred target in the incidents SISA investigates.
A review proves who held which entitlement at a point in time, not that access stayed constrained afterward. Privilege sprawl, orphaned accounts, and session-level abuse all develop between review cycles — which is why SISA pairs attestation with continuous control validation through Pulse.
Session hijacking is the theft of an authenticated session token, letting an attacker operate as a trusted user after login. MFA validates the login event itself, so once the session exists, the attacker inherits its trust — detection has to happen at the behavior level, not the access event.
Yes. Agentic systems increasingly execute with service-account-grade privileges, so a manipulated or compromised agent can act as a privileged insider that no traditional access review governs. Constraining agent privilege and monitoring agent behavior are becoming core insider-risk controls.
SISA's ProACT Agentic SOC monitors live system flows for the behaviors that signal misuse — anomalous service-account activity, developer-to-production access, lateral movement — rather than relying on access logs alone. For suspected active abuse, SISA's DFIR team runs internal forensic investigation and compromise assessment to surface the foothold directly.
