🚀 We’re launching Agentic Deep Scan Our next-generation vulnerability scanner for web, APIs, and mobile apps (iOS, Android, soon HarmonyOS). We’re the first and only platform delivering deep agentic scanning for mobile, while also covering web & APIs, helping security teams go beyond traditional scans with greater confidence and control.

Metabase's password reset was meant to check a token. It ran the attacker's SQL first. One extra field was enough to become admin and reach every database Metabase is connected to. No login needed. CVE-2026-72898 was exploited as a zero-day.

Every security team has tickets that matter but never get picked up. Ticket Agents take them on. Give one a job in plain words, and it picks up matching tickets and opens a PR for your engineers to review. Watch one find out why a server hit 100% CPU. Setup guide below 👇
