Proofpoint vs. Mimecast
Proofpoint vs. Mimecast Email Security
Investigate and stop threats faster—and skip the cleanup.
Reduce risk and manual work
Mimecast is a credible email security vendor, but teams that switch to Proofpoint report spending far less managing email security. With more precise detection, clearer visibility, and automated remediation, Proofpoint helps security teams stop attacks faster and cut manual effort dramatically.
How Proofpoint stacks up against Mimecast
Higher fidelity protection from BEC attacks
Mimecast has begun offering some new AI/ML and NLP techniques, but attacks still evolve more quickly than policy-driven controls can adapt. Thus, customers still report false positives and gaps in business email compromise (BEC) protection.
Proofpoint applies advanced AI and threat intelligence across the email threat lifecycle—from pre-delivery to post-delivery response—stopping 99.999% of email threats while reducing noise and manual investigation.
Smarter URL defense with less disruption
Mimecast users frequently cite overly aggressive URL blocking and rewritten links breaking legitimate workflows. Issues like these create friction for users as well as extra work for IT and SOC teams.
Proofpoint stops malicious URLs while enabling faster investigation and more automated remediation, so teams spend less time chasing link-related cleanup.
Threat visibility designed for SOC workflows
Mimecast offers message tracking and admin workflows, but many teams still report clunky UI, limited customization, and slow support, all of which can slow down response times.
Proofpoint gives analysts rapid access to the context they need—campaign-level views, targeting trends, and prioritized people risk—empowering them to act quickly and consistently.

What Gartner says about Mimecast
Independent analysis indicates Mimecast customers may encounter operational and strategic limitations.
“The company’s customer relationship management processes and support licensing lag behind those of other leaders in this Magic Quadrant.”
“Mimecast’s focus on human risk lacks a strong connection to email security outcomes.”
