MDR vs MSSP: What's the Difference?
MDR vs MSSP what's the difference and which is right for your team? Clear comparison of managed detection & response vs managed security service providers.
Definitions
MDR (Managed Detection and Response) = outsourced threat detection and response service. MSSP (Managed Security Service Provider) = outsourced security monitoring and management service. Both are managed, but differ in depth and scope.
Key differences
MDR focuses on threat detection and response. MSSPs focus on broader security management (firewall, VPN, compliance). MDR is typically more proactive. MSSPs are typically more operational.
When to choose MDR
You need active threat hunting and response. Your team can't investigate incidents. You want faster detection and response times. You need 24/7 coverage for threats specifically.
When to choose MSSP
You need broader security management (not just detection). You want someone to manage your firewalls, VPN, compliance. You need a single vendor for multiple security functions.
A third option: Agentic SOC
An agentic SOC platform provides the detection and response depth of MDR with the operational breadth of an MSSP but with AI automation instead of outsourced human analysts.
