Mimecast Advanced Email Security and Kaspersky Security for Mail Server are leading email security solutions. Mimecast appears superior in offering broader support and pricing options, while Kaspersky leads in spam filtering and real-time malware detection.
Features: Mimecast offers robust sandboxing, seamless Microsoft 365 integration, and advanced threat remediation. Its user-friendly admin console enhances usability. Kaspersky provides strong real-time protection, reliable malware detection, and comprehensive spam prevention. It effectively blocks suspicious emails and integrates well with security platforms.
Room for Improvement: Mimecast needs better detection rates and streamlined reporting. Its business model and pricing for archival data extraction raise concerns, as does complex management. Improvements in technical support responsiveness are also needed. Kaspersky can enhance license renewal and customization options, and should aim to offer SIEM-like capabilities.
Ease of Deployment and Customer Service: Mimecast offers deployment flexibility with public, private, and hybrid clouds. Installation is straightforward, but technical support could be more reliable. Kaspersky supports on-premises and hybrid deployments with generally good support service, although some users desire better remote session engagement.
Pricing and ROI: Mimecast is more costly, with additional fees for licenses and support, yielding moderate ROI due to high prices. Kaspersky is competitively priced and cost-effective, offering strong functionality without excessive costs. Mimecast’s premium costs impact its ROI perception compared to Kaspersky's balanced offerings.
