The startup Virtru Inc., which assists businesses in preventing unwanted access to their data, has raised $50 million in Series D funding.

The investment was disclosed by Fortune today. Bessemer Venture Partners, Foundry, and The Chertoff Group joined Iconiq in leading the investment.

Based in Washington, D.C. In 2012, Virtru was founded with the goal of commercializing TDF, an open-source file format. Will Ackerly, the primary architect and co-founder of Virtru, created the technology while working for the National Security Agency in the United States. It is intended to enable businesses to safely exchange private information with one another.

TDF connects files to a server under the control of the company that produced them. The files are encrypted on this server, and only authorized users can decode them. Additionally, TDF allows access to be withdrawn if necessary.

Virtru offers a cloud platform that helps businesses control how their employees share company data with other parties by utilizing TDF. Before files leave the company network, the software encrypts them. Virtru claims that a centralized interface allows users to control who has access to the records and to withdraw that access.

Other cybersecurity protections are also offered by the platform. Employees may watermark shared files, set an expiration date, and keep an eye on how they’re being accessed. Such files can only be opened by the receivers through a cloud application run by Virtru and triggered with one-time codes.

The business offers multiple variants of their TDP-powered cybersecurity technology for sale. In addition to versions that link with Google Workspace and Microsoft 365, there is a stand-alone file sharing service called Virtru Secure Share. The latter technologies have the ability to encrypt emails in addition to business files.

Virtru Private Keystore, another Virtru product, assists businesses in managing the encryption keys they use to protect their data. The program creates an audit trail that documents the usage of encryption keys, the company claims. It is simpler to prove adherence to cybersecurity laws with this log.

The company says that their platform can protect third-party information in addition to a corporation’s own data. Sensitive information, including credit card details, is found in incoming emails and encrypted by a program called Data Protection Gateway.

There are almost 6,700 organizations that have adopted the platform. Several government organizations, Salesforce Inc., Capital One Financial Corp., and other big corporations are among the company’s clients.

“Our goal is to establish TDF as the industry standard for data-centric security, enabling government organizations and private businesses to work together safely in the AI era,” Ackerly stated.

Proceeds from this investment round will be used by Virtru to expedite its attempts to create new products. The business is developing new cybersecurity features aimed at safeguarding workloads related to analytics and artificial intelligence.
