Remote Engine

We are excited to announce MetaDefender Aether 3.0.0, OPSWAT’s next-generation unified zero-day detection solution. With this release, the proven MetaDefender Sandbox dynamic analysis engine is now fully integrated into MetaDefender Aether as Layer 2, strengthening Aether’s multi-layered detection architecture and delivering deeper, faster, and more scalable threat analysis at the perimeter.
