Cyberattacks are no longer rare shocks—they’re a daily reality. From ransomware shutting down hospitals to phishing draining fintech wallets, the threat landscape is escalating. Now, an Indian cybersecurity startup is betting big on artificial intelligence to outsmart hackers before they strike.
CloudSEK, headquartered in Bengaluru, has just raised $19 million in Series B funding led by MassMutual Ventures, with backing from Tiger Global, India Quotient, and Redstart Labs. The goal? To make predictive cybersecurity the new standard for enterprises worldwide.
⚡ The Problem: Cyber Threats Are Evolving Faster Than Defenses
In 2025, global cybercrime costs are projected to cross $10.5 trillion annually.
Traditional tools—firewalls, endpoint detection—react after the damage begins.
Enterprises today ask not if they’ll be attacked, but how soon.
This is the gap CloudSEK aims to close: predicting breaches before they happen.
🤖 The Solution: CloudSEK’s Predictive Intelligence
CloudSEK’s flagship platform, XVigil, doesn’t wait for alerts. It continuously scans the surface web, deep web, and dark web for early signals of attacks—phishing kits, leaked credentials, data exposure—then translates them into actionable intelligence.
Key features:
✅ Real-time threat alerts before damage escalates
✅ Contextual risk scoring so security teams know what to prioritize
✅ AI-driven incident recommendations to cut response time
This isn’t just defense. It’s cyber foresight.
What is CloudSEK?
CloudSEK isn’t just another cybersecurity firm. It’s an AI-powered platform built to detect the earliest signs of a cyberattack—often weeks before it occurs.
Instead of acting after damage is done (like most traditional tools), CloudSEK focuses on:
- Predicting Initial Attack Vectors (IAVs)
- Spotting leaked credentials
- Flagging exposed APIs
- Identifying compromised vendors
This proactive approach makes CloudSEK a game-changer in predictive threat intelligence.
