Choose Mandiant if
- Enterprise organizations wanting threat intelligence integrated directly into MDR from 500+ frontline analysts
- Multi-vendor EDR environments (CrowdStrike, Microsoft Defender, SentinelOne all supported without agent swap)
- Google Cloud Platform customers wanting native SecOps integration
- You need SaaS and Network coverage included in base pricing
Choose SentinelOne if
- Organizations already running SentinelOne Singularity wanting platform-native MDR without adding another vendor
- Government and regulated industries needing FedRAMP Moderate and High certified MDR with $1M breach warranty
- Teams prioritizing AI-first detection with Purple AI Athena and unique Windows Rollback ransomware recovery
- Breach warranty matters to you (SentinelOne offers one, Mandiant does not)
What’s actually different
Buyer brief
Updated 2026-04-09
Fit. Mandiant's primary differentiator is threat intelligence. With 500+ analysts across 30+ countries and the M-Trends report drawing from 450,000+ consulting hours annually, no MDR provider matches that intelligence depth. SentinelOne integrates Google Threat Intelligence into Wayfinder MDR but doesn't operate its own research operation at that scale.
Response. Mandiant works with your existing EDR (CrowdStrike, Microsoft Defender, SentinelOne) without requiring an agent swap. SentinelOne's MDR only monitors Singularity. If you might change EDR platforms in the next few years, Mandiant doesn't force a rebuild.
Cost and scope. SentinelOne's response actions are broader: endpoint isolation, process termination, file quarantine, network containment and custom playbooks. Mandiant is limited to host containment and network containment through the MDR service, with no process kill, file quarantine or account disable. SentinelOne publishes an 18-minute MTTR against a contractual 60-minute SLA. Mandiant publishes no MDR-specific detection or response metrics. SentinelOne offers a $1M breach warranty and bundles IR in the Elite tier. Mandiant charges separately for IR through a retainer with a 2-hour response SLA. Mandiant's estimated pricing is ~$83,000/year. SentinelOne's platform runs $180-230/endpoint/year before the unpublished MDR bolt-on, which can exceed that quickly depending on endpoint count.

How does Mandiant pricing compare to SentinelOne?
Mandiant pricing: Third-party buyer data reports an average Mandiant software cost around $83,000/year. Treat this as a Mandiant buyer benchmark, not a clean Managed Defense MDR quote. SentinelOne pricing: SentinelOne platform pricing is separate from the MDR add-on. Third-party comparison data reports Vigilance MDR around $15-30+/endpoint/year, while SentinelOne public platform tiers and enterprise bundles remain separate or custom. Watch for with Mandiant: ~$83K+/year estimated, premium enterprise pricing; IR retainer is separate and must be purchased independently for full incident response. Watch for with SentinelOne: Platform license ($179.99-$229.99/endpoint/year) is required before MDR, significant prerequisite cost; MDR pricing is a bolt-on fee not shown on the public pricing page.
