Reputation
Trusted for deep IR pedigree and Complete Response methodology. Gartner Peer Insights 4.6/5 (26 reviews). KuppingerCole MDR Leader 2023. Lower market visibility than pure-play MDR brands (~0.4% PeerSpot mindshare). December 2025 CrowdStrike migration generates mixed reactions around vendor lock-in.
