Key learnings from peers

Valuable Features

Trellix Advanced Threat Defense offers remarkable features such as automatic threat remediation, effective threat detection and response, user-friendly administration, stable performance, and excellent integration with various systems. Its networking capability, comprehensive system unity, easy setup, and reliable sandboxing stand out. Users appreciate the e-policy Orchestration trader and behavioral retro-inspection. The intuitive UI, minimal training requirement, scalability, and competitive pricing further enhance its value.
  • "If a system admin can put in the patience to read and constantly update the ePO system in terms of rules, enforcing them at regular intervals, you can safely go to sleep every night."
  • "The most valuable features are the administration console and its detection and response module."
  • "I see ROI, as it stops in excess of twenty-five malware events per month, all of which could be critical to the business."

Room for Improvement

Trellix Advanced Threat Defense requires a user-friendly interface and improved integration with the active directory. Simplifying deployment and enhancing cloud readiness are critical. Users request AI incorporation, better scalability, faster threat processing, enhanced remote capabilities, and automatic Microsoft IP updates. They prefer a consolidated cloud offering and an API for email management. Scalability is a concern compared to competitors, along with limited HTTPS interface support.
  • "Make the ATD appliance a part of the whole product offering and take the whole thing onto the cloud."
  • "I would like to see future versions of the solution incorporate artificial intelligence technology."
  • "This product does the job, but it is not flexible enough to do new environments yet."

Pricing

Trellix Advanced Threat Defense generally receives feedback about its high cost yet superior value compared to industry standards. Users report licensing fees around one million dollars annually. Pricing is seen as competitive, especially with Symantec's reduced market presence, contributing to a more dynamic pricing environment. Some users perceive the product as being affordably priced.
  • "Our licensing fees for this solution are approximately one million dollars per year."
  • "The product is expensive, but it is better than the rest of them in the industry."

Popular Use Cases

Trellix Advanced Threat Defense is primarily used for protection of servers and workstations, networking, endpoint security, and malware detection, exemplified by its successful handling of WannaCry.

Some report helpful technical support, but response times can be lengthy, especially for smaller companies. Support from a Bangalore center is highly rated.

Deployment

Trellix Advanced Threat Defense's initial setup varied among users.

Some users had dedicated teams managing deployment, lessening their direct involvement in implementation.

Scalability

Trellix Advanced Threat Defense is praised for its flexibility in scaling, especially for versions on hand. However, challenges arise in cloud environments, where expansion capabilities are moderate. Users vary in the extent of their utilization, indicating untapped potential. In deployment scenarios involving large teams across multiple sites, it supports thousands effectively.

Author infoRatingReview Summary
RSSI at SDIS494.5I've used Trellix Advanced Threat Defense for 10 years with no issues; it's reliable and automated, though reporting is difficult and lacks an API for internal email inspection, which would improve visibility and control.
Head of Client Infrastructure at a computer software company with 201-500 employees4.5Our use of Trellix Advanced Threat Defense focuses on client management and security, utilizing its firewall and antivirus features. Its standout aspect is e-policy Orchestration, unique among competitors; however, an auto-update tool for Microsoft IPs is needed.

Cybersecurity Manager at a manufacturing company with 10,001+ employees4.0No summary available
Tech consultant at select softwares4.5I found this system incredibly effective for malware blockage, stopping WannaCry with zero failures. Its DXL client is a strength. While ATD integration needs improvement, I recommend it for its stability, scalability, and high ROI.
Programming Analyst at a tech services company with 201-500 employees3.5I primarily use this solution for threat detection, finding its administration console and detection and response module most valuable for network visibility. I would like to see future versions incorporate artificial intelligence technology.
CISO at W.L. Gore & Associates3.5I rate this solution 7/10. It excels at endpoint security, preventing many malware events. While stable with good support, its lack of cloud readiness is a major drawback, making it unsuitable for cloud environments.
Works at a tech services company with 11-50 employees3.5I find the product very scalable, but its initial setup is complex, and customer service is slow to respond. I also wish deployment was simpler and less expensive, as the current version is a pain.
