May 20, 2025
The funding round attracted participation from both Indian and US investors, including MassMutual Ventures, Inflexor Ventures, and several strategic backers, reflecting strong confidence in the company's growth trajectory.
Rahul Sasi, Co-founder and CEO, noted that over 60% of the company's new revenue is derived from international markets, with the US emerging as the fastest-growing region.
Despite its expansion efforts, CloudSEK remains cash flow positive and is nearing profitability, demonstrating its solid financial health.
CloudSEK's AI-based threat intelligence platform continuously monitors an organization's attack surface, including its supply chain and digital infrastructure, to identify vulnerabilities and protect sensitive information.
CloudSEK, a Bengaluru-based company specializing in AI-driven cyber threat prediction, has successfully raised $19 million in Series A2 and B1 funding rounds to bolster its proactive cybersecurity measures.
Looking ahead, CloudSEK plans to announce a Series B2 funding round to attract new investors and facilitate partial exits for early backers, further supporting its growth ambitions.
As part of its expansion strategy, CloudSEK plans to build a team of 100 employees in the US over the next two to three years.
The platform, known as Nexus, consolidates open-source data, allowing security teams to analyze intelligence in real time and detect vulnerabilities and attack patterns.
CloudSEK has garnered a strong reputation in the cybersecurity industry, achieving a 4.8-star rating on Gartner Peer Insights and receiving accolades from industry leaders.
Sasi also highlighted the connection between rising cybercrime and geopolitical tensions, noting that economic downturns often lead to increases in cyber threats.
The company has experienced remarkable growth, achieving a five-fold increase in revenue over the past three years, alongside a tripling of its Annual Recurring Revenue (ARR) in the last two years.
With its innovative approach, CloudSEK is positioned to lead a shift in the cybersecurity landscape, emphasizing the importance of anticipating threats rather than just responding to them.
