What is OpenAEV?

OpenAEV is industry’s first open-source, threat-informed exposure validation platform. It allows you to continuously assess, prioritize, validate and remediate exposures across your attack surface – at a human and technical level.

Simulate real-life attack scenarios, validate exploitable paths, and assess team readiness to prove cyber resilience – for tools, people, and processes!

We have conducted numerous crisis exercises. It is easy to use, very intuitive , allows for an unlimited number of players and exercise catalog, while creating a completely realistic environment for the players. The platform takes into account the needs of the users and the customer support is excellent.

I’m impressed with Filigran’s pragmatic, execution-focused approach to CTEM. Rather than adding more tools or operational overhead, their model focuses on measurable outcomes. That’s what practical CTEM should look like — outcome-driven, integrated, and scalable.

From a technical standpoint, It’s open-source, meaning that you have the possibility to contribute to it easily. Then, the number of connectors for enrichers, external sources are very varied, meaning that a lot of external sources are easy to integrate.

The realism of OpenAEV injects (emails and SMS as they would happen in real life) creates a real sense of urgency and stress, which is exactly what we aim for in our exercises.
