“Adapt OpenAEV's open, extensible architecture to your environment, not the other way around. Deploy with or without an endpoint agent, across cloud, on-prem, or multi-tenant setups, and integrate easily with your existing tools via injectors, executors, and collectors — including your own EDR. Simulations and their results are completely transparent and configurable, giving you full control over how validation fits into your stack.”
