Mimecast MSSP Providers
Mimecast is a cloud-based email security platform that provides protection against phishing, malware, spam, data loss, and business email compromise. The platform offers email gateway security, URL protection, attachment sandboxing, impersonation detection, and email continuity services. Mimecast also provides email archiving for compliance and e-discovery requirements.
MSSPs manage Mimecast deployments by configuring email security policies, monitoring threat detections, investigating phishing incidents, and managing quarantine workflows. Mimecast's cloud delivery model simplifies multi-tenant management for providers serving multiple client environments.
Choosing an MSSP for Mimecast
When evaluating Mimecast MSSPs, find providers with hands-on experience managing Mimecast Email Security, Targeted Threat Protection, and email archiving across multi-tenant environments. They need to know how to configure email gateway policies, URL protection, attachment sandboxing, and impersonation detection rules tailored to your organization's communication patterns. Ask how the provider handles quarantine management, phishing incident investigation, and policy adjustments when new email-borne threats emerge. Providers that also run SIEM or endpoint detection platforms alongside Mimecast can deliver tighter security operations overall.
A strong Mimecast MSSP engagement goes beyond email filtering into full email security management. The right provider monitors Mimecast threat dashboards, investigates targeted phishing campaigns, and delivers regular reports on attack trends and blocked threats. They handle email continuity planning, manage archiving and compliance configurations, and coordinate with your internal team on user-reported phish triage. Whether you need full-service management or co-managed support to back up an in-house team, a provider with real Mimecast platform knowledge keeps your email defenses tuned against current threats.

How to Evaluate an MSSP for Mimecast
- Ask about the provider's approach to Mimecast policy tuning, since overly aggressive filtering causes business disruption from blocked legitimate emails.
