Voltage, Tablus join forces

Voltage Security and Tablus have joined forces to help their customers find, control and protect sensitive data better, Voltage officials said today.

Government and other large organizations often don’t know what data they have, said Guido Appenzeller, Voltage’s founder and chief technology officer.

Tablus’ products scan devices on users’ networks to find and inventory data, Appenzeller said. It can block information from leaving, quarantine it or delete it when data is not where it’s supposed to be, he said.

Voltage uses its customers’ e-mail addresses as the basis for its Identity-Based Encryption (IBE) product, which creates a public-key function to encrypt data, Appenzeller said.

IBE automatically encrypts data to lower the risk of privacy violations and information breaches, Appenzeller said. The product can use Tablus’ group, departmental or policy identifiers as basis for encryption keys, powering role-based access to data.

Voltage runs the address through an elliptic curve cryptographic algorithm to create an encryption key similar to that used in public-key infrastructure (PKI), Appenzeller said.

Using e-mail addresses makes ID encryption easier and cheaper to deploy than PKI because it eliminates the need to create, store and manage public-key certificates, he said.

The companies introduced the integration of Voltage IBE with Tablus Content Sentinel earlier this month. They plan to announce integration of IBE with Tablus Content Alarm NW and Content AlarmDT by the end of 2006.
