Siris Capital completes purchase of Juniper Networks® Junos® Pulse Business and BYOD Innovator MobileSpaces

San Jose, California, October 1, 2014 – Siris Capital today announced that it has completed its acquisition of the Junos Pulse business from Juniper Networks, the industry leader in network innovation, and incorporated that business under the name, Pulse Secure, LLC. Siris Capital will continue to operate and invest in Pulse Secure as an independent company with the mission to empower business productivity through secure and seamless mobility. Concurrent with the completion of the Junos Pulse acquisition, Pulse Secure has completed the acquisition of MobileSpaces, a leading provider of mobile security for the app-centric enterprise.

Pulse Secure, which has more than 200 patents related to the portfolio in secure access and mobile security, will continue to innovate across its market-leading product portfolio, including the Pulse VPN solution, the Pulse network access control (NAC) gateway, Pulse’s mobile security solutions and branded endpoint clients that run on Windows, Windows Phone, Mac OS X, iOS, Linux and Android. Industry veterans and Siris Executive Partners Alfred Zollar and Andrew Monshaw will lead Pulse Secure, serving in the roles of Chairman and CEO, respectively.

“We are excited to launch Pulse Secure as an independent company. It begins operations with a unique combination of assets, from network infrastructure to mobile technologies,” Zollar said. “Most importantly, we’re building upon this business with more than 200 employees who are leading security experts in VPN, NAC and mobile.”

With the successful closure of the sale and formation of Pulse Secure, Rami Rahim, executive vice president and general manager, Juniper Development and Innovation, said, “This is an exciting day for Pulse Secure and we look forward to our partnership moving forward. Juniper remains committed to ensuring customers and partners experience a seamless transition and see no interruptions in sales or support.”

Pulse Secure will focus on two strategic priorities. First, extending its products’ best-in-class market leadership in the VPN and NAC markets, and second, investing in capturing the emerging market opportunity to enable enterprise network mobility via unified management that includes cloud-based delivery of policies to appliances and mobile devices. The MobileSpaces acquisition underpins Pulse Secure’s commitment to the continued investment in its strategy to create a unified user experience for remote and on-campus mobility that spans PCs and mobile devices with central policy and administration.

“Pairing MobileSpaces’ BYOD workspace with our VPN and network-access control products ushers in the next-generation workforce by giving them easy, yet secure, mobile access to the services and applications they need,” said Monshaw. “We’re thrilled to be bringing MobileSpaces’ innovative products and people to the new Pulse Secure.”
