Email Security Providers

32 providers

Email Security covers the controls that protect your organization from phishing, malware delivery, business email compromise (BEC), and spam. Managed services include gateway filtering, attachment sandboxing, URL rewriting, click-time protection, DMARC/DKIM/SPF configuration, and user-reported phishing workflows.

Email is still the number one delivery method for cyberattacks. Effective protection requires continuous policy tuning, fast response to new phishing campaigns, and integration with threat intelligence. A managed approach keeps defenses current without constant attention from your internal IT team.

How to Evaluate an MSSP for Email Security

  • Ask about the provider's response time for quarantine release and phishing triage, since slow email security operations disrupt business workflows.
  • Understand whether the MSSP manages email authentication records (DMARC, DKIM, SPF) as part of the service, which protects against domain spoofing.
  • Clarify how the provider handles user-reported phishing messages and whether there is a feedback loop to improve detection policies.
  • Ask whether the service includes business email compromise (BEC) detection, which requires behavioral analysis beyond standard spam and malware filtering.
