Detonate safely, observe everything
Run suspicious apps on real hardware and watch what they do. There is no emulator for them to detect, so they don't hold back.
Pack C · Security
Apps detect emulators, test environments, and analysis tools, and change their behavior when they find them. What you observe in a lab is not what happens in the world.

Run suspicious apps on real hardware and watch what they do. There is no emulator for them to detect, so they don't hold back.
Turn ongoing detonations into a stream of indicators and behavioral insight, drawn from what malware actually does, not what it looks like.
For mobile security vendors: test detection products at scale against live threats behaving naturally on real devices.
Analyze threats that never arrive as an app: SMS phishing, malicious QR codes, NFC and relay attacks, on the real channels they abuse.
Automated reports with a security score for every app analyzed, plus pattern recognition that categorizes behavior so you can triage at scale.

Sentinel is pre-launch. These are the conversations we're looking for.
We're always open to conversations with investors who work in deep tech. Book a meeting and we'll show you where Sentinel is.
We're interviewing practitioners in security, privacy, compliance, and mobile QA. Thirty minutes of your experience will shape what we build.
We work with a small number of teams as design partners, tuning Sentinel against their real apps before launch. Partners are first onto the beta. Slots are limited.
