CloudSEK raised $10 Mn in an extended Series B round (B2 tranche).
The round is a mix of primary (new shares) and secondary (existing shareholders selling) capital.
Connecticut Innovations (CI), the venture capital arm of the US state of Connecticut, participated.
CloudSEK claims it is the first Indian-origin cybersecurity company to get funding from a US state-backed fund.
The funds will accelerate US expansion and establish a regional hub in Connecticut for operations and partnerships.
CloudSEK will hire strategic local talent and build collaborations with local corporate partners and universities.
The company wrapped up its broader Series B round with this B2 tranche.

The fundraise comes amid a healthy spurt in cybersecurity investment driven by the rise of AI.
AI enables attackers to deploy automated sophisticated threats like deepfakes and smarter phishing.
Investor interest is growing as enterprises spend more on protecting systems and digital infrastructure.
The global cybersecurity market is projected to become a $562.72 Bn opportunity by 2032.
