Voltage Security Introduces Integration Kit for ISVs Tackling Enterprise Data Privacy

Integration with Charter Partners Proofpoint and Tablus Provides Easy-to-Manage and Scalable Data Privacy Throughout the Enterprise

RSA Conference, San Jose, Calif., February 14, 2006 – Voltage Security, Inc., a global leader in enterprise privacy management, today announced the new Voltage Enterprise Privacy Management Integration Kit™ and a charter group of companies using the kit to deliver comprehensive data privacy solutions. The charter companies include: Proofpoint, a leader in enterprise-class messaging security and Tablus, a leading provider of content protection solutions.

The Voltage Enterprise Privacy Management platform is a foundation for consistent enforcement of privacy policies across enterprise applications and information. The Voltage Enterprise Privacy Management platform is powered by the breakthrough Voltage Identity-Based Encryption (IBE), offering the lowest administrative overhead and highest usability of any encryption solution available today. Voltage IBE, representing the next generation in public-key cryptography, marries identity (for instance, a common email address) with encryption to provide fine-grained access control for private data across the enterprise.

“Our vision for the Voltage Enterprise Privacy Management platform is to bring together policy, identity and encryption to enable more sophisticated access control and policy enforcement and to protect the privacy of enterprise data: data-in-use, data-in-motion and data-at-rest,” said Sathvik Krishnamurthy, president and CEO of Voltage Security. “Our customers have consistently been requesting a holistic approach to data privacy solutions. This release of the Voltage Enterprise Privacy Management Integration Kit empowers other security providers, such as our charter partners, to leverage the power of Voltage IBE by tightly integrating it with their solutions.”

“Our corporate customers are increasingly concerned with key management among multiple silos of encryption,” said Trent Henry, senior analyst at Burton Group. “Using a standardized encryption capability to simplify encryption, policy, and access control of private data across the enterprise is a significant step forward for everyone.”

Charter Integration Kit Partners: Proofpoint and Tablus

Charter integration kit partners include: Proofpoint, a leader in enterprise-class messaging security and Tablus, a leading provider of content protection solutions.

Proofpoint’s breakthrough messaging security technologies enable organizations of all types to reduce the costs and risks associated with email—today’s most important business communications channel—and other messaging streams. Proofpoint is the first data protection and messaging security vendor to fully integrate Voltage IBE technology as part of a comprehensive content security solution. Since its introduction in July 2005, Proofpoint’s IBE-powered, policy-driven encryption solution has been quickly adopted by enterprises with as many as 150,000 users across vertical industries including healthcare, financial services and manufacturing.

“Proofpoint has been on the forefront of email content security and compliance. Voltage IBE technology, incorporated in the Proofpoint Secure Messaging module, helps provide the automatic, content-aware encryption today’s enterprises need to protect private and confidential information, eliminate risks associated with data leakage and ensure compliance with a wide variety of outbound messaging policies,” said Gary Steele, president and CEO of Proofpoint.

For data at rest, Tablus Content Sentinel™ enables identification, classification, and remediation of sensitive information dispersed throughout the enterprise on servers, desktops, and laptops. Providing the ability to delete, quarantine, and now encrypt the data with Voltage IBE, Tablus gives enterprises the ability to control access to confidential and private data, wherever it resides in the organization. For data in motion, Content Alarm NW™ with Voltage IBE will block, quarantine or encrypt sensitive data leaving the organization according to pre-determined corporate policy. For data stored on desktops, Content Alarm DT™ will be integrated with Voltage IBE to restrict data usage and encrypt selected data according to corporate policy.

“For the first time, enterprises will be able to automatically identify sensitive data and quarantine, delete or encrypt that data in real time based on content classification,” said Jim Panté, president and CEO of Tablus. “Voltage and Tablus plan to integrate Voltage IBE with all three Tablus offerings to simplify the process of encrypting sensitive data at rest, in motion and in use.”

Voltage Enterprise Privacy Management Integration Kit

The Voltage Enterprise Privacy Management Integration Kit is available today for ISVs interested in adding robust policy-based encryption capabilities to data privacy solutions. The kit provides all the components needed to quickly integrate with Voltage IBE and the Voltage Enterprise Privacy Management platform. Integrated applications can immediately take advantage of Voltage’s advanced key management, policy, and usability capabilities.

The Voltage Enterprise Privacy Management Integration Kit includes:

Voltage IBE application program interface (API’s), to enable developers to easily utilize the widest range of cryptographic algorithms, including Identity-Based Encryption
Voltage IBE Server, to provide extremely low-overhead key management and key distribution services for ISV applications
Management interfaces, to enable the aggregation of systems management information to provide a common management view
Policy interfaces, to provide centralized control over cryptographic and other usage aspects of the integrated solution
Custom authentication adaptors, to enable a wide variety of mechanisms for authenticating users, services and applications that need to access to cryptography services
User interface templates, to customize the look-and-feel of the final data privacy solution

About Voltage IBE

Voltage IBE is a public key cryptography system that uses common identities (such as an email address or screen name) as public keys, eliminating the need for certificates, Certificate Revocation Lists (CRL) and other costly infrastructure. Voltage IBE results in a solution that is easy to implement and easy to manage, without the overhead and cost inherent in traditional security solutions. Voltage IBE is ideal for use with financial services customers and medical patients who expect communication to be kept private and secure and also want ease-of-use and low-cost. Voltage IBE solutions are:

Easy to implement and easy to manage – eliminates the overhead and costs inherent in traditional security solutions such as PKI
Highly scalable – no storage of keys or messages, and no need to contact online servers; allows the solution to scale dramatically without the need for additional infrastructure
Easy to use – no need for end users to worry about keys, certificates or multiple inboxes.
