Mimecast Advanced Email Security Reviews Summary
Author infoRatingReview Summary
Solution Architect Cybersecurity at Microland Limited4.0I rate Mimecast 8.5, finding it excellent for email security, DMARC, and compliance, with good ROI and stability. However, it must expand beyond email to compete with broader SASE/XDR platforms.
Email Security Engineer at Logic Infosecurity5.0I've used Mimecast Email Security for two years and find it the best traditional email gateway, with strong phishing protection and stability, though its interface is complex and could benefit from improved API integration and user-friendliness.
Senior Security Engineer at ManpowerGroup4.0I use Mimecast Email Security mainly for intercepting phishing attempts. Its AI-driven structure, Abnormal functionality, and targeted threat protection are effective. However, improvements are needed in phishing, DNS, and key rotation. I find it to be cost-effective overall.
IT Manager at a logistics company with 201-500 employees3.5I've used Mimecast Web Security for over five years, finding it effective in email and URL protection, though improvements are needed. Stability and reporting are decent, but I rely on my MSP for management, support, and monitoring.
Senior Tech. Lead at WE4.0We are conducting a POC to compare Mimecast with other email security solutions. Mimecast effectively blocks phishing and impostor attacks, although it requires improvement in reducing false positives. It offers ROI by mitigating financial risks associated with phishing.
Co-Founder & VP-Sales at QuantumShield Technologies LLP4.5I've used Mimecast Email Security for seven months and find its features like archiving and data loss prevention useful. While it's stable and effective, it's pricey in India and lacks local support. I'd rate it nine out of ten.
Information Security Analyst at Enfield Central Library4.5I've been using Mimecast Email Security for four years as our primary email gateway, efficiently scanning and removing threats before reaching users. The tool offers valuable insights into email interactions and has no significant areas needing improvement.
Head of IT & Innovation at Shoreham Port Authority2.5I encountered issues with Mimecast Email Security, particularly with their sender IP being poorly rated by Microsoft, which led to blocked emails. This problem prompted me to consider alternative solutions since I wasn't fully aware of all its features.
Managing Director at Conekt Business Group4.0I use Mimecast for email security across my clients, benefiting from its effective spam filtering and email signature features. However, frequent blocklisting of outbound servers has become a concern. Although its ROI is hard to quantify, it's our preferred solution.
Senior Manager at Massmart4.0I use this stable, scalable solution for email threat protection and archiving. While vendor lock-in and threat response time are drawbacks, I value its 99-year retention and recommend it overall, rating it an 8/10.
