Accenture and Leonardo Win €200 Million NATO Contract for Secure Cloud Digital Transformation

The PBN contract is valued at about €200 million and covers seven years, expiring in 2033, with the signing taking place at the NATO Summit Defense Industry Forum in Ankara.
The program has been approved by the North Atlantic Council as a NATO-wide capability program, establishing the Protected Business Network as a foundational digital backbone across the alliance.
Leonardo will implement a Zero Trust architecture secured by its Global Cybersec Platform, described as an AI-driven, multi-agent cyber defense system.
The platform will support approximately 29,000 NATO users across the alliance through a multi-cloud environment provided by NCIA, replacing legacy systems with a standardized cloud operating model.
The signing and rollout are framed as a major step in NATO’s digital transformation, with officials describing the move as enabling faster, more secure decision-making and interoperability across Allied forces.
Accenture and Italy's Leonardo have won a roughly €200 million, seven-year contract to build NATO's new secure cloud platform, according to Nasdaq. The deal, signed with the NATO Communications and Information Agency, covers a project called the Protected Business Network and runs through 2033.
The contract was signed at the NATO Summit Defense Industry Forum in Ankara, Decode39 reported. It marks one of the largest digital infrastructure deals in the alliance's recent history, serving about 29,000 NATO users across member nations.
The Protected Business Network will replace NATO's aging legacy systems with a single, standardized cloud platform, according to Mirage News. The goal is to let NATO staff and military personnel access classified data securely, no matter where they are operating.
The platform runs on a multi-cloud environment managed by the NCIA. Decode39 described it as NATO's new 'digital backbone,' designed to speed up decision-making and improve coordination across Allied forces in different theatres.
Leonardo's role centers on cybersecurity. The Italian defense firm will deploy what it calls a Zero Trust architecture — a security model where no user or device is automatically trusted, even inside the network. It runs on Leonardo's Global Cybersec Platform, Nasdaq reported.
The system uses AI and multiple automated agents to detect and respond to threats in real time. Democrata noted that the platform is designed to harden NATO's digital infrastructure against increasingly sophisticated cyberattacks targeting the alliance.
The Protected Business Network is not just a vendor contract. The North Atlantic Council — NATO's top decision-making body — has approved it as an official NATO-wide capability program, according to Mirage News. That gives it a higher status than a typical procurement deal.
TechMarketView reported that the seven-year term gives Accenture and Leonardo time to design, implement, and then operate the platform. Officials described the program as enabling faster, more secure collaboration across the alliance's 32 member states.
The deal is a significant milestone for both companies. For Leonardo, it strengthens its position as a key cybersecurity partner for Western defense organizations. For Accenture, it adds to a growing portfolio of large-scale government cloud contracts across Europe.
Decode39 noted that the contract reflects NATO's broader push to modernize its technology infrastructure amid rising digital threats. The alliance has made cloud adoption and cyber resilience top priorities, particularly since Russia's invasion of Ukraine in 2022.
