CloudSEK, an India-based AI-powered cybersecurity company, has secured $19 million in Series A2 and B1 funding rounds aimed at accelerating its global expansion and advancing its artificial intelligence models.
The round was led by top-tier investors including Mass Mutual Ventures, Inflexor Ventures, Prana Ventures, Tenacity Ventures and strategic backer Commvault, alongside continued support from early backers such as StartupXSeed, Neon Fund, Exfinity Ventures, and the Meeran Family, founders of Eastern Group.
Founded in 2015 by cybersecurity expert Rahul Sasi, CloudSEK provides a proactive threat intelligence platform that detects Initial Attack Vectors (IAVs) like leaked credentials, exposed APIs, and compromised vendors—weeks before an incident occurs.
“We built CloudSEK to predict threats before they escalate, unlike traditional solutions that act post-breach,” said Sasi.
“This predictive rather than forensic approach empowers enterprises to stay ahead.”
Over 60% of CloudSEK’s new revenue is now international, with the U.S. as its fastest-growing market. The company continues to scale while remaining cash flow positive—a rare feat among startups at this stage.
The last funding round was nearly three and a half years ago, where CloudSEK raised $7M in Series A. According to VP of Finance Kalyan Kumar Vattipalli, a Series B2 extension is in the works, to attract more global investors and enable partial exits.
CloudSEK’s approach has earned strong validation from the market, including a 4.8-star rating on Gartner Peer Insights from 195 enterprise clients across finance, health, tech, and government sectors
