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.
Program Specialist at GE4.5I find Trellix Email Security easy to deploy and manage, with a dashboard, URL rewriting, tracing and reporting that cut spam/phishing about 65%. It’s stable, scalable and cost‑effective, but routing can be slow, long emails delay, and false positives occur.
Project Manager at Nestle4.5I use Trellix Email Security to accurately stop phishing and malicious email, with an easy dashboard, strong trace/attack visibility, stable scalable performance, and excellent support. It integrates well with threat intelligence and Microsoft 365 ATP, but needs fewer false positives and better reporting.
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.
Consulting Systems Engineer at Boomslang Tech4.0I’ve used Trellix Email Security for two years with Exchange to stop phishing and malware, leveraging sandboxing and URL reputation to catch zero-days and reduce SOC workload. It’s stable and valuable, but the admin console and dashboards need improvement.
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.
