Learn about MDR

Plain-English guides for security teams evaluating Managed Detection & Response.

Fundamentals

What is MDR?

Managed Detection & Response explained. What it does, what it doesn't, and how it fits into your security program.

MDR vs MSSP

Both are outsourced security services, but they work very differently. When to choose which.

MDR vs EDR

EDR detects threats on endpoints. MDR adds human analysts who investigate and respond. Most organizations need both.

MDR vs SOC-as-a-Service

MDR is a function. SOCaaS is an entire outsourced security operation. Knowing the difference prevents overbuying.
