Bangalore, India – May 20, 2025CloudSEK, a leader in AI-powered cyber threat prediction and intelligence, has raised $19 million across its Series A2 and B1 funding rounds. The 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. Notably, 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.

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.

Team CloudSEK (L–R): Bofin Babu,Girish Menon, Rahul Sasi, Mayank Satnalika, and Syed Shahrukh Ahmad — driving innovation in predictive cybersecurity.

The newly raised capital will fuel CloudSEK’s continued 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.

“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.”

CloudSEK’s differentiated approach has resonated globally, earning the company a 4.8-star rating on Gartner Peer Insights across 195 reviews, making it one of the most recommended vendors in the cybersecurity space.

“Early visibility into threats is no longer optional. CloudSEK’s predictive intelligence helps enterprises take control of the narrative—before attackers do,”
said Dr. Durga Dube, CISO of a Fortune Global 100 company.

“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.”
Rohit Razdan, Partner, Tenacity Ventures

“CloudSEK has grown 3x in ARR over the last 24 months and continues to grow well above industry standards,” said Kalyan Kumar Vattipalli, VP of Finance at CloudSEK.
“The round attracted significant interest from global financial investors, and we will soon be announcing Series B2 as an extension of B1, both to onboard new investors and to facilitate partial exits for some of our early backers.”

With this funding and a strategic investor on board, CloudSEK is doubling down on its vision to make predictive threat intelligence a global cybersecurity standard for —empowering organizations to stay ahead of increasingly sophisticated threat actors.
