Security startup Vaultive tackles cloud-based encryption

Office 365 is the Microsoft Office suite of desktop applications and hosted versions of Microsoft's server products delivered and accessed over the Internet.

Security startup Vaultive debuts this month with a product to remotely manage encryption of email data that enterprises may choose to keep in the Microsoft Office 365 cloud service.

Elad Yoran, chairman and CEO of New York City-based Vaultive, says the firm is tackling how enterprises themselves can control encryption of data they elect to keep in cloud environment. Vaultive's approach to "data encryption in use," as Yoran calls it, is based on technology designed as an encryption-proxy using the Advanced Encryption Standard that allows the enterprise to target data to be stored in the cloud and encrypt it so that it's held in scrambled form there.

The company's first product, Vaultive for Hosted Exchange, is intended to encrypt email and attachments held in Microsoft Office 365. It's priced on a per-user per-month basis that starts at a couple of dollars and drops based on volume.

Security concerns about data in the cloud are many, Yoran points out, noting they range from the possibility that "the cloud provider might get hacked" to "a rogue employee working for the cloud provider would access my data," to "data intermingling in a multi-tenant environment."

Yoran says he knows directly from Microsoft that sometimes it will receive a legal subpoena to turn over data and Microsoft will do that without necessarily telling the customer. But with the cloud data encryption control in the hands of the enterprise, that couldn't be done without the enterprise knowing about it because Microsoft couldn't decrypt the data without the customer's cooperation.

Vaultive's approach encrypts the cloud-stored data, and allows only the authorized individuals to run an encrypted search query at the Exchange server hosted by Microsoft and "serves the encrypted results back," as the Vaultive proxy then decrypts it to be read in cleartext, says Yoran. Vaultive anticipates it will release other Microsoft-cloud-oriented products in the future as well as products designed to work with custom applications.

Vaultive, said to have about two dozen employees, was founded in 2009 by Ben Matzkel, chief strategy officer, and CTO Maayan Tal, who manages the engineering team and serves as general manager of Vaultive Israel. Both previously worked at McAfee.

This is the fourth security startup for Yoran, whose history includes executive positions at Sentrigo, MediaSentry, Riptech and Broadview International. Vaultive was started with a few million dollars in angel funding, and later obtained about $10 million in venture capital from 406 Ventures, New Science Ventures and Harmony Partners.
