Problem
You receive SOC, EDR, and XDR quotes without knowing what is actually needed.
Expected outcome
A simple decision framework to avoid unnecessary spending.
EDR: protect endpoints and servers
EDR detects suspicious endpoint behavior and helps isolate compromised machines.
- Malware and abnormal behavior detection.
- Isolation of infected endpoints.
- Visibility into processes and files.
SOC: analyze and respond 24/7
A SOC combines alerts, logs, and human expertise to triage and respond to incidents.
- Multi-source correlation.
- False-positive triage.
- Response playbooks.
Choose based on maturity
An SMB often starts with EDR plus essential monitoring, then evolves toward managed SOC.
- EDR alone for lower risk and available IT team.
- Managed SOC for critical activity or customer requirements.
- XDR/SIEM for multiple environments to correlate.
Frequently asked questions
Does EDR replace a SOC?
No. EDR is a tool; SOC is a monitoring and response capability.
Does an SMB need 24/7 SOC?
Yes if it has critical systems, customer requirements, or limited internal resources.
What is XDR?
XDR correlates signals from endpoints, email, identity, cloud, and network.
