CloudSEK Raises $19 mn in Series B1 to Scale Predictive Cybersecurity Platform

AI-powered cyber threat prediction and intelligence startup CloudSEK has raised $19 million across its Series A2 and B1 funding rounds.

The startup will use the funds to continue product innovation and global expansion, with a focus on advancing its AI models and platform integrations.

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

Founded in 2015 by cybersecurity researcher-turned-entrepreneur Rahul Sasi, CloudSEK was created with a mission to build a safer digital future by proactively predicting and mitigating cyber threats.

What began as a research-driven initiative has since evolved into one of the industry’s most trusted threat intelligence platforms, serving 250+ enterprises across banking, healthcare, technology, and the public sector.

 “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, CEO and Co-Founder CloudSEK, said.

The funding round included participation from a mix of India- and US-based investors, such as MassMutual Ventures, Inflexor Ventures, Prana Ventures, Tenacity Ventures, and select strategic investors, including Commvault.

, Meeran Family (founders of Eastern Group), StartupXSeed, Neon Fund and Exfinity Ventures are among CloudSEK’s earlier backers and continue to support the company’s long-term vision.
