Features, pricing, ratings, and pros & cons — compared head-to-head.
CAI (Cybersecurity AI) is a free red-team & adversary emulation tool by Alias Robotics. Filigran OpenAEV is a commercial breach & attack simulation tool by Filigran. Compare features, ratings, integrations, and community reviews side by side to find the best red-team & adversary emulation fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams at startups and small consulting firms who need LLM-powered penetration testing without licensing friction should build on CAI; the framework's 500+ supported LLMs and 15+ agents let you run offensive automation in your own environment at zero cost. The GitHub community (3,641 stars) and on-premises deployment mean you control the entire supply chain, which matters when handling client data during assessments. Skip this if your organization lacks Python engineers to customize agents or needs vendor-backed SLAs; CAI prioritizes offensive capability over the detection and response coverage that enterprise security teams typically require.
Mid-market and enterprise teams with mature EDR deployments will get the most from Filigran OpenAEV because it validates whether your existing detection stack actually catches real attacks instead of just assuming coverage. The platform's MITRE ATT&CK-aligned simulation library and AI-assisted scenario creation mean you're testing threats your environment actually faces, not generic templates, and the agentless architecture lets you start validating immediately without EDR replacement costs. Skip this if you need a turnkey solution that works without an EDR already in place; OpenAEV assumes you own the detection layer and want to stress-test it.
