Sentinari

Sentinari is an Irish company that builds a mobile-first platform for employee reporting of suspicious activity, which it calls Human Signal. Employees use a single app to report suspicious events on any channel, including scam calls, SMS, WhatsApp messages, and in-person approaches. The reports reach the security team as structured events. The platform includes several capabilities: - Frictionless reporting: employees report suspicious events from their mobile device in seconds. - A dedicated channel: security teams send targeted alerts and advisories to employees through the Sentinari app, outside of email, and can see who has read them. - Automatic polling: polls, thresholds and targeting are triggered by incoming reports, for example asking colleagues whether they received a scam call from the same number. - Instant containment: when a report indicates credential exposure, Entra ID sessions and tokens can be revoked automatically, without an analyst. Sentinari integrates with SIEM and SOC workflows so that employee reports feed into the technical security stack as telemetry. The company positions its product as a complement to security awareness training and phishing simulations, not a replacement. It targets organizations that want to move employee reporting beyond email-based tools to cover voice, SMS and messaging app threats. The founders previously worked at Corrata, Asavie, Vodafone, Akamai and Baltimore, on products such as mobile security, SASE/VPN, IoT connectivity and cryptography. Sentinari is a member of Cyber Ireland.
