Cisco Secure Email Threat Defense Reviews Summary
Author infoRatingReview Summary
Senior Cybersecurity Engineer at a financial services firm with 11-50 employees3.5I've used Cisco Secure Email Threat Defense for years; it's powerful and flexible but complex to set up and maintain. While effective with threat detection and compliance, backend controls and pricing could be more user-friendly and competitive.
Enginner at Millennium Information Technologies4.0I found Cisco Secure Email Threat Defense effective for threat analytics and automation, though it needs improvements like IP restrictions and better log support. Setup was quick, support is strong, and I’d rate it 8 out of 10.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees3.5I use Cisco Secure Email Threat Defense for advanced email threats like phishing. Its clawback feature is effective, but it lacks in analytics and integration. Despite false positives, it offers good value with a 65% ROI.
Principal Consulting Engineer, Founder, Own at Jolly Security Inc4.0I use Cisco Secure Email Threat Defense as the core email gateway for my domain, offering protection and threat intelligence. While the physical appliance is discontinued, slight improvements in customization and cloud features would enhance its modernity.
IT Professional at a construction company with 1,001-5,000 employees3.5We use Cisco Secure Email Threat Defense for email security, finding it robust and reliable with high protection against threats, particularly excelling in file analysis services. However, Cisco's broad focus has slightly shifted its attention from this product.
Presales Consultant - Cybersecurity at a computer software company with 201-500 employees2.5I use Cisco Secure Email Threat Defense primarily for email security and spam filtering with Microsoft Office 365. Its most valuable feature is the powerful cloud-based Talos threat mechanism, though improvements are needed in cybersecurity.
Senior Consultant at Velocis Systems5.0I find this email security solution very easy to deploy and use, with excellent stability and support. While it is a bit expensive, its competitive intelligence and reliability make it a 10/10 choice for email protection.
IT Professional at a construction company with 1,001-5,000 employees4.0I highly recommend this stable, scalable email security solution for its excellent sandboxing and malware protection, which I find superior to Microsoft Defender. Setup was simple, though I wish pricing was lower. I rate it 8/10.
AVP- Sales at Velocis Systems4.5I find Cisco Secure Email Cloud Mailbox offers a comprehensive email protection portfolio, stable performance, and excellent support. While it lacks advanced phishing and is premium-priced, its integrated capabilities and value for Cisco-centric environments earn it a 9/10.
Product Manager-Cyber Security & Networking Active at a tech services company with 501-1,000 employees4.0I rate Cisco Secure Email Cloud Mailbox an eight out of ten. It's a comprehensive, stable, and scalable email security solution, though expensive. My key suggestions are adding monthly billing and more granular DLP for improved service.
