Company profile
researched Aug 2026Voltage Security was a Cupertino, California-based provider of data-centric security software. Founded in 2002 at Stanford, the company built on research in mathematics and cryptographic systems and held numerous patents. Its initial premise was that identity-based encryption (IBE) could serve as a better alternative to public key infrastructure (PKI) in the enterprise; in 2003 it launched an early version of identity-based email encryption that removed the need for a public key when sending encrypted email.
As the anticipated horizontal PKI market did not materialize, the company repositioned around email encryption and data-at-rest encryption, and later expanded to protecting corporate data as it moves across company systems, including cloud storage and mobile access. Its capabilities spanned data classification, payments security, encryption, tokenization and enterprise key management, spanning data center, cloud and Hadoop environments. In February 2015 HP announced its intent to acquire the company and integrate it with its HP Atalla data and payments security software.
Founding story
Voltage was founded in 2002 at Stanford by professor Daniel Boneh and three of his students, on the hypothesis that PKI would become a critical part of the enterprise and that identity-based encryption could offer a better alternative. None of the founders had held a full-time job before starting the company, and Sathvik was brought in as CEO within the first few months.
Business model
Voltage Security sold enterprise encryption and data protection software to large organizations, serving over a thousand enterprise customers worldwide.
Traction
More than a thousand enterprise customers worldwide; particular focus on payment data through work with large payment processors.
Latest developments
On February 9, 2015, Hewlett-Packard announced the acquisition of Voltage Security for an undisclosed sum, to be folded into the HP Atalla security division; the companies expected the transaction to close by the end of the first half of 2015.

History
The company was founded in 2002 by Stanford professor Daniel Boneh and three of his students, among them Guido Appenzeller and Matt. Sathvik joined as CEO when the company was only a few months old and led it through the acquisition. An early version of identity-based email encryption shipped in 2003. Venture financing totaling roughly $27 million was raised in 2005 and 2007. After the original PKI-platform hypothesis failed to play out, the company repositioned around email and data-at-rest encryption and later payments and enterprise data protection. In February 2015, HP announced it would acquire the company.
