Mandiant Managed Defense

Mandiant Managed Defense is a premier managed detection and response (MDR) service that pairs frontline threat intelligence and elite security analysts with customer security technologies to detect, investigate, and contain advanced cyber threats 24/7/365. Rather than relying on generic automated rules, Managed Defense is continuously fueled by Mandiant's unmatched visibility into real-world threat actor campaigns, zero-day exploits, and advanced evasion techniques gathered from thousands of breach investigations worldwide. Operating across leading endpoint, network, and multi-cloud security platforms—including Google Cloud, CrowdStrike, and Microsoft Defender—Mandiant analysts conduct continuous proactive threat hunting to uncover subtle indicators of compromise that evade automated controls. When an intrusion is identified, analysts perform rapid, deep-dive forensic investigations and execute decisive, hands-on containment actions to sever adversary access, stop lateral movement, and neutralize malware before damage occurs. Clients receive transparent communication, detailed incident debriefs, and strategic posture guidance from designated security advisors. Mandiant Managed Defense provides organizations with authoritative threat defense, minimizing breach risk and ensuring operational peace of mind.
