Verizon today acquired the PrecisionAccess solution and other software-defined perimeter (SDP) related assets from Vidder. Terms of the transaction were not disclosed. Verizon said it was just buying specific assets and Vidder remains a private company with behind-the-scenes assets. Vidder's customer-facing website already redirects to Verizon.

Vidder’s technology is integrated into Verizon’s SDP service. About a year ago, Verizon said it planned to add Vidder’s SDP security to its Virtual Network Services (VNS).

The SDP software works by isolating communications between applications and end-user devices. It takes applications off the public internet and creates a real-time connection between the user and the application that exists only for the duration of that session and then disappears, explained Shawn Hakl, Verizon’s vice president of new products and innovation, in 2017.

The technology at Verizon blocks connectivity from unknown devices and makes them invisible to anyone without approved access. And at Verizon, Vidder’s PrecisionAccess solution provides unified access control across internal networks, clouds, and external users, continually ensuring that only trusted devices used by entitled users and devices can see and access trusted applications.

“This acquisition enables us to further build out our software-defined suite of services, creating a unified networking and security solution, which we believe is best-in-class when it comes to protecting organizations against cyberattacks,” said Victoria Lonker, Verizon’s vice president of network and security product management, in a statement.
