IT security software company Ivanti has acquired two security companies: Enterprise mobile security firm MobileIron and .corporate virtual network provider Pulse Secure

In a statement on Tuesday, Ivanti said it bought MobileIron for $872 million in stock — with 91% of the shareholders voting in favor of the deal — and acquired Pulse Secure from its parent company Siris Capital Group, but did not disclose the buying price.

The deals have now closed.

Ivanti was founded in 2017 after Clearlake Capital, which owned Heat Software, bought Landesk from private equity firm Thoma Bravo, and merged the two companies to form Ivanti. The combined company, headquartered in Salt Lake City, focuses largely on enterprise IT security, including endpoint, asset and supply chain management. Since its founding, Ivanti went on to acquire several other companies, including U.K.-based Concorde Solutions and RES Software.

If MobileIron and Pulse Secure seem familiar, both companies have faced their fair share of headlines this year after hackers began exploiting vulnerabilities found in their technologies.

Just last month, the U.K. government’s National Cyber Security Center published an alert that warned of a remotely executable bug in MobileIron, patched in June, allowing hackers to break into enterprise networks. U.S. Homeland Security’s cybersecurity advisory unit CISA said that the bug was being actively used by advanced persistent threat (APT) groups, typically associated with state-backed hackers.

Meanwhile, CISA also warned that Pulse Secure was one of several corporate VPN providers with vulnerabilities that have since become a favorite among hackers, particularly ransomware actors, who abuse the bugs to gain access to a network and deploy the file-encrypting ransomware.
