Trellix Email Security Reviews Summary
Author infoRatingReview Summary
Senior Technical Support Engineer at Digitaltrack4.5We use Trellix Email Security on AWS for blocking DMARC and detecting threats, offering cloud threat protection, but need better phishing defense and customizable dashboards. It's cost-effective compared to competitors like Sophos, with an average operational cost and potential significant savings.
Team Manager at Ford4.5I’ve used Trellix Email Security as our gateway for four years; it’s stable, scalable, and user-friendly, with strong malware analysis and quarantine. However, URL-threat blocking and settings are complex, reporting needs work, and false positives are high.
Security Consultant at Trinexia4.5I find Trellix Email Security excellent for anti-phishing across cloud and on-premises environments, offering high stability and scalability. My main concern is its uncompetitive, expensive pricing, which impedes sales, and the difficult setup due to lacking documentation.
Information Security Engineer at Nhq Distribution Ltd4.0I find Trellix Email Security improved over previous versions, with strong mail filtering and dynamic response. However, I believe its email filtering reporting needs more detail, especially for restricted file transmissions, which customers often request.
Senior Infrastructure Engineer at a tech company with 501-1,000 employees4.5I use Trellix Email Security for perimeter filtering, and it reliably reduces spam and malware with strong automation and granular policies; setup was simple and it’s stable. It’s better than old McAfee gateways and cheaper than Mimecast, but needs SSO.
