Data security firm Digital Guardian has acquired $66 million in new capital it will use to bolster its roster of products for data protection, advanced threat protection and endpoint detection and response.

The move comes after Digital Guardian in October scooped up Code Green Networks to expand its presence in the healthcare realm.

"The target of both insider threats and advanced cyberattacks remains the theft of sensitive data," Digital Guardian CEO Ken Levine said in a statement. "Corporations must prioritize protecting the data itself from exfiltration."

Contributing to this new round of funding are previous investors GE Pension Trust (advised by GE Asset Management), Fairhaven Capital Partners, Loring Wolcott & Coolidge, Special Situation Funds and Brookline Venture Partners.

New technology investors LLR Partners, Mass Mutual Ventures, the corporate venture capital arm of Massachusetts Mutual Life Insurance Company (MassMutual), and the Venture Capital Unit of Siemens Financial Services joined in the funding with previous investors GE Pension Trust, Fairhaven Capital Partners, Loring Wolcott and Coolidge, Special Situation Funds and Brookline Venture Partners.
