    24/7 analysts included in the subscription who tune policies, hunt threats, apply virtual patches, and hand-validate alerts before they reach your team.

  • API Protection

    Automatic API cataloging with behavioral analysis and fingerprinting to catch abuse, enumeration, and business logic attacks against north-south API traffic.

  • Bot Management
