01Introduction
Running a round-the-clock SOC takes a team of analysts, detection engineers and incident responders. Most companies can't hire that. MDR sells the outcome as a service instead.
02What is MDR?
MDR differs from a traditional managed security service provider (MSSP) mainly in doing the investigation and response, not only forwarding alerts.
03How MDR works
An MDR engagement is a shared operating model.
- 1.
Deploy sensors
Endpoint, identity and cloud telemetry is connected to the provider's platform.
- 2.
Monitor and triage
Provider analysts watch alerts 24/7 and discard false positives.
- 3.
Hunt
Analysts search proactively for activity the rules did not catch, informed by threat intelligence.
- 4.
Respond
Confirmed threats are contained directly or escalated with clear instructions, per the agreed runbook.
04Threats and risks
Outsourcing detection doesn't outsource the exposure.
Limited business context
The provider doesn't know which API is revenue-critical or which account is a test fixture.
Coverage boundaries
Custom applications and business logic are usually out of scope for MDR monitoring.
Remediation stays with you
The provider contains an incident. Your engineers still fix the root cause.
Response delays
Approval chains between provider and customer can slow containment when minutes matter.
05How Parameter helps
Parameter works on the part MDR hands back to you: the weaknesses themselves.
Root causes found and proven
The pentesting agents find exploitable flaws in your applications and show exactly how they are used.
Fixes in developers' workflow
Sentinel reviews every pull request and comments with a fix before vulnerable code merges.
