How to use this list
Do not assume
Response can mean advice, remote containment, or full incident handling. Confirm the exact handoff before shortlisting.
Ask before shortlisting
- Confirm what the provider owns after an alert and what still stays with your team.
- Ask which response actions are pre-approved and which need your approval.
- Check how incidents are escalated when your team is offline.
Category background
These SOC providers are designed to integrate with the security tools you already own. Instead of replacing your existing CrowdStrike, Splunk, Microsoft Defender, or other investments, they plug in and layer expert analysts, automation, and detection logic on top.
Why Choose a Vendor-Agnostic Provider
If your organization has already invested in security technology, you don’t want to throw that away. These providers maximize the value of your existing stack by adding the human expertise and 24/7 monitoring that turns tools into actual security outcomes. They also avoid vendor lock-in — if you decide to switch MDR providers later, your underlying tools stay the same.
What to Look For
When evaluating vendor-agnostic providers, check the breadth and depth of their integrations. Some support 50 tools, others support 200+. Also look at how deeply they integrate — a shallow integration might only ingest alerts, while a deep integration can take response actions through your existing tools’ native capabilities.
Questions
What does "works with your existing tools" mean?
These providers don't require you to buy their proprietary security platform. Instead, they integrate with the SIEM, EDR, cloud security, and identity tools you already own — like CrowdStrike, SentinelOne, Microsoft Defender, Splunk, or Microsoft Sentinel — and layer their analyst expertise and automation on top.
Why would I choose this over a provider that brings their own platform?
If you've already invested in security tools (EDR, SIEM, firewall, etc.), a vendor-agnostic provider lets you get more value from those investments rather than paying for redundant technology. This approach avoids vendor lock-in and makes it easier to switch providers in the future.
Can these providers work with any security tool?
Most vendor-agnostic providers support the major platforms — CrowdStrike, SentinelOne, Microsoft Defender, Splunk, Microsoft Sentinel, and Palo Alto Networks are nearly universal. Some support 100-200+ integrations across EDR, SIEM, cloud, identity, and email platforms. Check each provider's integration list for your specific tools.
