How to use this list
Use it when
- Use this list when one part of your environment needs managed monitoring or response coverage.
Do not assume
- Coverage does not always mean action. Some providers monitor a source but cannot contain threats there.
Ask before shortlisting
- Confirm which telemetry sources are included by default.
- Ask whether response actions work on this surface or only alerting is included.
- Check whether reporting and detection tuning are part of the managed service.
Category background
These SOC providers monitor your email systems for phishing, business email compromise (BEC), malicious attachments, and account takeover. Email remains the #1 initial attack vector for most organizations.
Why Email Monitoring Matters
Over 90% of cyber attacks start with email. Phishing, spear-phishing, and BEC schemes bypass traditional spam filters by using social engineering rather than malware. SOC providers that monitor email detect suspicious forwarding rules, inbox manipulation, credential harvesting links, and impersonation patterns — often catching attacks that email gateways alone miss.
