CloudSEK, a contextual AI firm that predicts cyber threats, raises $19 million in funding

[[{“value”:”

AI-powered cyber threat prediction and intelligence startup CloudSEK has raised $19 million across its Series A2 and B1 funding rounds, which included participation from a mix of India- and US-based investors.

Investors who participated in the funding rounds are MassMutual Ventures, Inflexor Ventures, Prana Ventures, Tenacity Ventures, and select strategic investors, including Commvault. Notably, the Meeran Family (founders of Eastern Group), StartupXSeed, Neon Fund and Exfinity Ventures are among CloudSEK’s earlier backers.


What does CloudSEK do?

CloudSEK, a contextual AI company that predicts cyber threats, claims that it provides services to over 250 enterprises across banking, healthcare, technology, and the public sector.

The company, which was founded in 2015 by cybersecurity researcher-turned-entrepreneur Rahul Sasi, said it will use the raised capital to fuel its product innovation and global expansion, with a focus on advancing its AI models and platform integrations.

Unlike traditional tools that respond after an incident, it identifies Initial Attack Vectors (IAVs)—the earliest signs of a potential breach, such as leaked credentials, exposed APIs, or compromised vendors.


Leadership comments

“We built CloudSEK to predict the initial attack vector and stop threats before they hit the headlines with the goal of preventing threats before they escalate,” said Rahul Sasi, Co-founder & CEO of CloudSEK.

“Unlike conventional threat intelligence that focuses on indicators of compromise after an attack, our platform detects the earliest signals—leaked credentials, exposed APIs, compromised vendors—weeks before an incident unfolds. That’s our version of threat intelligence: predictive, not forensic.”

“Today, over 60% of our net new revenue comes from international markets, with the U.S. emerging as our fastest-growing region. We’ve achieved this scale while staying cash flow positive. This round—backed by top financial and strategic investors—not only validates our vision but reinforces what we’ve believed from day one: cybersecurity must be proactive, not reactive,” Rahul Sasi added.

“CloudSEK has created a great product based on cutting-edge AI, appropriate for the security needs of top global companies. Tenacity is excited about backing and working closely with Rahul and his team to help build a great global technology product company from India,” said Rohit Razdan, Partner, Tenacity Ventures.
