Avaya Government Cloud Achieves Prestigious IL4 H Certification, Reinforcing Commitment to National Security
Avaya is currently the only provider with a combined contact center and unified communication solution certified and available at IL4 H
Morristown, NJ – June 1, 2026 – Avaya, a global leader in enterprise software solutions, today announced that its Avaya Government Cloud solution has achieved the U.S. Department of War (DoW) Impact Level 4 High (IL4 H) certification, a Provisional Authorization (PA) granted by the Defense Information Systems Agency (DISA). This certification confirms that the Avaya Government Cloud solution for unified communications and contact center meets the rigorous DISA and DoW Cloud Security requirements for handling up to Controlled Unclassified Information (CUI) level Voice and Contact Center communications. The Avaya IL4 H Cloud Service is fully backwards interoperable with existing operational JITC certified premises-based and DISA voice services (DSN).
The IL4 H certification means that the DoW can now leverage Avaya’s dedicated, single-tenant cloud environment to modernize their communications infrastructure with enhanced security and flexibility, providing a trusted path to the cloud while protecting existing on-premises investments. Avaya is currently the only provider with a combined contact center and unified communication solution certified and available at IL4 H. This makes Avaya the sole, mission-ready choice for any DoW agency that needs to run a contact center within a high-security network environment.
Rooted in the Avaya Aura platform, IL4 H certification for the Avaya Government Cloud delivers the advanced communication capabilities federal and DoW clients depend on to achieve their mission-critical priorities in a solution that’s backed by heightened levels of security and supported by a team of dedicated U.S.-based professionals.
"Recognized as the gold standard for protective sensitive government data, IL4 H certification underscores our unwavering dedication to meeting the government’s stringent requirements, while providing secure, reliable, and flexible solutions," said Jerry Dotson, Vice President, Avaya Government Solutions. "We understand the critical nature of government operations and the importance of mission assurance.”
