Mimecast Email Security and Microsoft Exchange Online Protection compete in the email security category. While Mimecast offers robust features, Microsoft EOP seems to have the upper hand due to its ease of integration with Microsoft 365 and straightforward deployment.
Features: Mimecast provides extensive features such as email sandboxing for thorough threat analysis, effective security filtering, and comprehensive archiving capabilities. It also offers targeted threat protection and phishing countermeasures. Microsoft EOP integrates seamlessly with Microsoft 365, offering effective anti-spam and anti-phishing protection, robust malware defenses, and valuable identity protection features.
Room for Improvement: Mimecast needs better detection rates for malicious emails, simplified admin tasks, and more accessible support options. Users seek reduced complexity and pricing. Microsoft EOP could improve its handling of gray emails, simplify its technical support, and enhance integration with non-Microsoft platforms. Users desire more AI-driven features and advanced threat protection in both solutions.
Ease of Deployment and Customer Service: Mimecast can be deployed across various environments, but challenges exist with its support system. Microsoft EOP is particularly praised for easy deployment within Microsoft's cloud environment and better customer support, despite having response-time issues.
Pricing and ROI: Both Mimecast and Microsoft EOP are considered expensive. Mimecast faces criticism for complex pricing and additional fees. Microsoft EOP offers better cost efficiency, especially when bundled with other Microsoft services, appealing more to those already invested in its ecosystem. ROI for both depends on organizational needs and budget.
There is definitely a return on investment when using Mimecast, as it blocks phishing emails, reducing the risk of significant financial losses.
