Q: Who buys and manages Trellix XDR inside a company?

Trellix XDR is usually owned by Enterprise Endpoint, Email & XDR (McAfee Enterprise / FireEye). Decision-makers include CISO, VP of Information Security and CIO; Security Architect and SOC Manager shape the choice, and SOC Analysts and Security Engineers use it day to day. Our Trellix XDR list can include any of these roles.

Q: Which Trellix XDR products or editions can I target?

You can target accounts by the Trellix XDR products they run, including Trellix Endpoint Security (ENS), Trellix Email Security, Trellix Network Detection & Response, Trellix Helix XDR and Trellix Data Loss Prevention. Tell us which edition or module matters and we filter the list to those accounts.

Q: What other software do Trellix XDR customers use?

Trellix XDR customers commonly also run Microsoft 365, Splunk, ServiceNow, Cisco and Tenable. Trellix XDR is often connected to AWS, so users of those tools overlap heavily. We can filter any list by this kind of stack overlap.

Q: What are the main alternatives to Trellix XDR?

The main alternatives to Trellix XDR are CrowdStrike, Microsoft Defender and Palo Alto Cortex. We also keep verified user lists for CrowdStrike, which is useful for competitive displacement campaigns.

Q: When are Trellix XDR customers most likely to buy?

Buying triggers we track for Trellix XDR accounts include endpoint replacement, government contract renewal, DLP program refresh and New CISO. A common pain point is Legacy McAfee and FireEye estates: customers modernise older agents and appliances.
