Microsoft [MSFT] signed an agreement to acquire Secure Islands, an Israeli data security firm, the company said Nov. 9.

Secure Islands offers data classification, protection, and loss prevention technologies for almost any kind of file, allowing customers to apply data protection to more application, Microsoft noted.

Current customers of Secure Islands include UBS AG [UBS], OSRAM, Vodafone [VOD], and Credit Suisse [CS]. Under the terms of the acquisition, Secure Islands will continue to sell its existing products and support its customers.

Their technology “enhances the data protection capabilities available today with Azure Rights Management Service, Microsoft’s cloud-based information protection solution,” Takeshi Numoto, corporate vice president of cloud and enterprise marketing at Microsoft, said in a blog post.

Both companies said they have been close partners, with Secure Islands using Microsoft’s rights management technology.

“By joining Microsoft, we will be able to extend and expand our vision. Microsoft has been a long time partner and its leadership in enterprise IT, its resources and global reach will help us innovate and deliver new information protection capabilities to both our current and new customer base,” Aki Eldar, CEO and co-founder of Secure Islands, said in a separate statement.

“This acquisition accelerates our ability to help customers secure their business data no matter where it is stored–across on-premises systems, Microsoft cloud services like Azure and Office 365, third-party services, and any Windows, iOS or Android device,” Numoto added.

Upon completion of the acquisition, Microsoft said it will integrate the Israeli company’s technology into Microsoft’s Azure Rights Management Service “to provide a flexible architecture able to meet the most rigorous protection and compliance requirements.”

Closing of the acquisition is subject to regulatory approval.
