Fenrir · Our offensive AI engine
Varden's sovereign AI engine for cybersecurity.
In Norse mythology, Fenrir is the wolf that even the gods struggled to chain. At Varden, it is the artificial intelligence engine that tests your defences the way a real attacker would, under mandate and under the control of our pentesters.
An AI that attacks like a hacker, under control
Designed and developed in-house by our ethical hacking experts.
An open source model hosted in Paris, with Scaleway, with no calls to services outside Europe: your data stays in the European Union.
Where consumer AI refuses to go, Fenrir reasons and tests like a real attacker, strictly within the scope you have authorised.
Tests run only under a signed mandate. Every finding is validated by a pentester before it goes into your report.

The Sentinel range, from automated to expert
What a hacker sees about you from open sources, without intrusion. It is not a penetration test.
External vulnerability scan run end to end by Fenrir, with your authorisation.
Penetration test orchestrated by Fenrir; a pentester validates every result.
Tailored penetration test led by our pentesters, assisted by Fenrir: unusual scopes, business logic, red team.
With any order of a Sentinel Advanced or Sentinel Expert penetration test, your one-year Sentinel Dashboard subscription is included: compliance, internal network and internet exposure, tracked on a single screen.
