US Department of Defense chooses Trellix to protect millions of email systems from zero-day threats

Trellix accelerates DoD cloud and Zero Trust Architecture adoption with advanced protection against email-borne threats.

Trellix, the cybersecurity company delivering the future of extended detection and response (XDR), has announced that the Defense Information Systems Agency (DISA) Zero Day Network Defense Program has selected Trellix to protect more than four million email inboxes across the US Department of Defense (DoD).

Building on a nearly two-decade-long relationship with DISA, Trellix email protection advances the agency’s Zero Trust Architecture (ZTA) adoption and will enable it to migrate on-premises infrastructure to the cloud.

Zero-day attacks are exploited by cybercriminals before known malicious markers or vulnerabilities have been identified and before protections or patches are deployed. Attackers use sophisticated phishing, spear-phishing and malicious attachments to exploit zero-day attacks via email, and the growing use of GenAI by cybercriminals makes email attacks easier to develop, plan and execute at scale.

“DISA supports DoD agencies in better conducting their missions while leading technology best practices and adoption across US government agencies,” said Gareth Maclachlan, Networking and Collaboration Security General Manager at Trellix. “Without secure email solutions, organisations face the growing threat of sophisticated actors entering their infrastructure to conduct espionage, steal or damage data. Protection for unknown email threats is imperative for all organisations, and even more critical for the agencies protecting national security.”

The flexible email security solution from Trellix includes advanced integrations with Microsoft Office 365 and third-party cybersecurity tools, enhancing DoD investments while meeting stringent DoD security requirements, including FedRAMP High and IL5 certification. With Trellix Email Security, the DoD benefits from:

  • Improved detection and prevention of nation-state attacks: Industry-leading hyper-automated detection stops more advanced persistent and nation-state threats than any other offering on the market. Along with consistent visibility and telemetry into attacker campaigns, the DoD is empowered with threat intelligence required to inform future email security plans and investments.
  • Reduced cost and maintenance: Cloud migration provides cost savings and ease of maintenance while ensuring the DoD has access to a flexible solution capable of operating in the cloud or on-premises.
  • Accelerated ZTA compliance: ZTA is a security model assuming users and devices inside and outside an organisation’s network have been breached and cannot be trusted. The Executive Order on Improving the Nation’s Cybersecurity aims to advance the nation’s cybersecurity posture through the adoption of ZTA-compliant technology across the Federal Government. Trellix Email Security supports the tenets of ZTA by ensuring protection against zero-day email attacks.
