Indian AI cybersecurity firm CloudSEK raises $19m to predict and stop cyber threats before they strike

Bengaluru-based cybersecurity firm CloudSEK has announced the successful closure of $19 million in funding across its Series A2 and B1 rounds. The round drew participation from notable global and Indian investors, including MassMutual Ventures, Inflexor Ventures, Prana Ventures, Tenacity Ventures, and Commvault as a strategic investor. Earlier backers such as StartupXseed Ventures, Neon Fund, Exfinity Ventures, and the Meeran Family (founders of Eastern Group) also reaffirmed their commitment to the company’s long-term growth roadmap.

Founded in 2015 by cybersecurity researcher Rahul Sasi, CloudSEK’s mission has remained consistent: to proactively prevent cyberattacks before they escalate into breaches. This capital injection will allow the company to invest further in enhancing its AI models, fortify product integrations, and accelerate expansion into international markets, particularly the United States, which has emerged as its fastest-growing geography.

What Sets CloudSEK Apart in the Cybersecurity Landscape?

CloudSEK’s AI-first threat intelligence platform stands out in a crowded cybersecurity marketplace by focusing on proactive threat detection rather than reactive response. The core differentiator lies in its ability to identify Initial Attack Vectors (IAVs)—the earliest indicators of a potential cyber intrusion, such as leaked credentials, exposed APIs, and compromised third-party vendors.

Unlike conventional cybersecurity platforms that focus on Indicators of Compromise (IOCs) after an attack, CloudSEK’s proprietary AI models enable clients to detect vulnerabilities weeks in advance. This forward-looking posture shifts the cybersecurity paradigm from forensic investigations to anticipatory defence—arguably a more scalable and cost-efficient model for large enterprises.

CEO Rahul Sasi emphasized that the company’s model of “predictive, not forensic” cybersecurity is enabling customers to act before their systems are breached. He noted that CloudSEK has stayed cash-flow positive, even while scaling rapidly, and now earns over 60% of its net new revenue from international markets, validating both product-market fit and strategic execution.

Who Are CloudSEK’s Investors and Why Are They Betting Big?

The investor mix in this round reflects confidence in both CloudSEK’s technology and its ability to scale globally. Among the participants, Commvault’s strategic backing signifies deep alignment with enterprise security priorities. Financial investors like Tenacity Ventures have shown particular excitement about the company’s ability to scale an enterprise-grade cybersecurity solution globally from an India-based hub.

Tenacity Ventures partner Rohit Razdan stated that CloudSEK is building a platform rooted in cutting-edge AI that aligns with the increasingly complex security requirements of Fortune 500 enterprises. Similarly, other backers lauded the platform’s real-world applicability, with Dr. Durga Dube, a CISO at a Fortune Global 100 company, underlining that early visibility into threats is now imperative—not optional.

From a performance standpoint, CloudSEK has posted impressive growth metrics, with 3x growth in Annual Recurring Revenue (ARR) over the last two years, as confirmed by Kalyan Kumar Vattipalli, the company’s VP of Finance. He added that the company is preparing for a Series B2 extension to onboard new investors and provide partial exits to early backers.

How Does CloudSEK’s Technology Work?

CloudSEK’s core product suite, XVigil, leverages Natural Language Processing (NLP), Computer Vision, and proprietary data models to scan publicly accessible sources, including dark web forums, code repositories, and cloud environments. These scans help organizations detect vulnerabilities, impersonations, and data exposures long before such indicators turn into real incidents.

One of the firm’s key innovations is its ability to correlate disparate digital signals into actionable insights. This predictive framework is particularly useful in identifying supply chain vulnerabilities, where a compromised vendor could be the starting point of a much larger breach.

The platform integrates seamlessly with existing SIEM, SOAR, and cloud security stacks—making it attractive to global CISOs looking for plug-and-play threat intelligence.

CloudSEK’s approach to solving the “signal-to-noise” problem has gained strong validation across sectors like banking, healthcare, e-commerce, technology, and critical infrastructure, serving over 250 enterprise clients globally.

What’s Next for CloudSEK in Terms of Global Growth?

The latest funding round marks a critical inflection point for CloudSEK. With this capital, the company plans to strengthen its presence in the North American and European markets, regions where predictive threat intelligence is becoming a board-level priority amid rising compliance pressures and ransomware threats.

CloudSEK is also focusing on product R&D to deepen platform capabilities and increase automation. As enterprise clients demand real-time threat mitigation and fewer false positives, the company aims to enhance its machine learning models to offer contextualised, enterprise-specific alerts.

Further expansion plans include developing multi-language threat detection capabilities, a feature that would help better serve global organizations across regions like Latin America, Southeast Asia, and the Middle East, where cyber threats often take a localized form.

What Is the Industry Saying About Predictive Cybersecurity?

There is growing consensus among analysts that proactive cybersecurity solutions—particularly those using AI and machine learning—are quickly becoming essential. With high-profile breaches affecting sectors from healthcare to aviation, boardrooms are now investing in threat intelligence platforms that promise visibility ahead of compromise.

CloudSEK’s consistently high user ratings, including a 4.8-star score across 195 verified reviews on Gartner Peer Insights, demonstrate growing user confidence in the company’s offering. This sentiment is echoed by multiple CISOs and threat analysts who have integrated XVigil into their SOC operations.

From a market standpoint, the demand for Cyber Threat Intelligence (CTI) solutions is expected to exceed $20 billion globally by 2030, according to industry forecasts. CloudSEK, with its India-engineered yet globally scalable platform, is well-positioned to capture a meaningful share of this evolving market.

Will CloudSEK Lead the Global Shift to Predictive Security?

With fresh funding, a strong international client base, and a well-defined roadmap, CloudSEK is aiming to lead a paradigm shift in cybersecurity. Its product-led growth strategy, supported by institutional investors and strategic partners, provides a compelling blueprint for scaling AI-driven cybersecurity solutions globally.

The next phase of growth could see the company become a standard-bearer for predictive threat intelligence, as organizations around the world move from reactive firefighting to proactive risk anticipation. As cybersecurity threats grow in complexity, CloudSEK’s early-warning infrastructure could become a foundational layer in the global enterprise security architecture.
