MATRIXIdentity Security for the GenAI Era.
GenAI blurs the line between human and machine identity. MatrixSentry protects every identity — human, bot, and service account — across the communication channels where they actually operate.
Auth-layer tools go silent after login.
Legacy identity tools catch the impossible-travel login. But what happens after authentication succeeds?
Today, Copilot acts under your credentials. AI agents delegate to other AI agents. Attackers exploit email and Teams chat to compromise identities, exfiltrate data, and poison enterprise LLMs. If you are only monitoring the authentication boundary, you are blind to the interaction layer where modern threats execute. MatrixSentry closes the gap.
Protect identities where they act.
We don't just scan messages. We baseline identities across email, chat, and IDP signals in a single inference loop.
- Delegation Chain Attribution: For AI agents acting under delegated permissions, we trace the delegation chain to distinguish human actions from agent actions — a critical capability no auth-layer tool provides.
- Rolling Behavioral Baselines: Every identity builds a dynamic 30-day behavioral profile. We map contact graphs, language markers, and active hours. Deviations — a new recipient burst, a sudden tone shift — trigger immediate detection.
- Cross-Channel Correlation: An identity acting anomalously in email and Teams chat is a stronger signal than either alone. We correlate behavioral deviations across Microsoft 365, Teams, and your IDP to catch multi-stage attacks that siloed tools miss.
- Autonomous Remediation: Detection triggers instant, autonomous response — email quarantine, Teams DLP enforcement, and real-time alert routing without waiting for a human to write a rule or update a signature.
Defend your Enterprise AI.
Stop external attackers from weaponizing your communication channels. MatrixSentry natively detects and intercepts External Prompt Injection Attacks (XPIA) and prompt injection attempts in email and chat before they can compromise your internal LLMs — with no endpoint agent required.
