Cybersecurity firm CloudSEK has raised $19 million in its Series A2 and B1 funding rounds from MassMutual Ventures, Inflexor Ventures, Prana Ventures, Tenacity Ventures, and Commvault. Existing investors, including the Meeran Family, StartupXSeed, Neon Fund, and Exfinity Ventures, also participated.

The funds will be allocated for AI model improvements, platform integrations, and worldwide growth—particularly in the US, its most rapidly expanding market.

This latest round follows a hiatus of almost three and a half years for the company based in Bengaluru. It had earlier secured $7 million in a Series A funding round spearheaded by MassMutual Ventures.

Established in 2015 by Rahul Sasi, CloudSEK offers predictive threat intelligence, concentrating on identifying Initial Attack Vectors (IAVs) like compromised credentials and exposed APIs.

“Our platform identifies the initial signs—leaked credentials, exposed APIs, compromised vendors—weeks before an incident occurs, unlike traditional threat intelligence that emphasizes indicators of compromise following an attack.” "That's our interpretation of threat intelligence: anticipatory, rather than investigative," remarks Rahul.

Sasi mentioned that more than 60 percent of the organization’s net new revenue is now generated from international markets, with the US becoming the rapidly expanding region. He highlighted that the company has achieved this size while staying cash flow positive.

CloudSEK presently caters to over 250 companies in industries like banking, healthcare, and technology, and has increased its ARR threefold in the last 24 months.

The firm intends to widen its Series B1 funding round into a B2 segment, targeting new investors and allowing early supporters to achieve partial exits.
