Pulse Secure will buy Brocade’s virtual application delivery controller (vADC) assets for an undisclosed amount. The vADC is part of Brocade’s IP networking assets that Broadcom said it wanted to divest when it announced its purchase of Brocade in November 2016.

The vADC deal, which includes a leased R&D facility in Cambridge, U.K., as well as associated customer support and maintenance contracts, is expected to close by mid-July.

Pulse Secure also said it will hire former Brocade employees that work with the vADC business. This team will work closely with Pulse after the deal closes to make sure customers continue to be supported.

Pulse Secure CEO Sudhakar Ramakrishna said in a blog post that the company will integrate Brocade’s vADC capabilities into its Pulse Secure Access Suite. Pulse makes security products for access control, SSL VPN, and devices.

“The combined company's nearly 750 employees post-acquisition will be uniquely focused on delivering secure access for people, devices, things, and services,” said Ramakrishna, in a statement.

Brocade’s vADC was one of the first fully virtualized application deliver controllers and can be provisioned on-premise in a public or private cloud, or even through one of the cloud services like AWS, Google, or Microsoft Azure.

Pulse Secure is owned by Siris Capital and was formed after Siris acquired Juniper Networks’ Junos Pulse business in 2014 for $250 million.

Pulse has about 20,000 customers that use its security products in 18 million endpoints.

Ramakrishna added that the combination of Pulse’s unified client, Policy Secure, with the vADC, will be a key development in the Internet of Things (IoT).

The company also has about 200 patents related to secure access and mobility security.

Siris Capital is a private equity firm focused on revamping mature telecom and tech companies that have a legacy business that is profitable but declining. A key part of Siris' strategy involves the virtualization of the network. Siris also owns Mavenir, and unified communications companies Polycom and PGi.

When Broadcom announced in November 2016 that it was buying Brocade, it said it would divest Brocade’s Ruckus Wireless assets as well as Brocade’s IP networking assets. Since then, Arris has said it will purchase the Ruckus assets and ICX switch business for $800 million. And Extreme said it would purchase Brocade’s data center networking assets for $55 million. Now Pulse Secure has stepped up to buy the vADC business.

But there are still other pieces of Brocade that haven’t been claimed including a virtual router and an SDN controller. There have been some rumors that a service provider might pick up the virtual router.
