The race to protect the digital world has created one of the fastest-growing and most successful industries today: cybersecurity. Every company, from global enterprises to the apps we use every day, relies on it to keep our data and systems safe. And nowhere is this race more intense than in the cloud - the invisible space where our information lives and our software runs.
For years, companies protected the cloud using a familiar routine: waiting for something to go wrong, getting an alert, and scrambling to fix it. That worked when threats moved slowly. But today, the cloud is bigger, faster, and more complex than ever. Businesses run thousands of interconnected services, and AI has completely changed how attacks happen. Now, AI-driven threats can spot weaknesses instantly - long before humans even know they’re there.
In a world where attacks move at machine speed, reacting after the fact simply isn’t enough. And that realization is what led to the creation of Blast Security.
“We’ve seen cloud complexity grow faster than teams can keep up. The only reliable way to reduce risk is to prevent it in the first place,” says Boris Vaynberg, co-founder and CEO of Blast Security.
Blast’s founding team - veterans from elite cyber units - learned this firsthand while working on a national-level cloud security mission. They saw that if you want to stop modern threats, you can’t wait for alarms. You need safety measures built into the system from the start.
This idea became the foundation for Preemptive Cloud Defense - a new approach focused on stopping risks before they turn into problems. As Nir Rothenberg, CISO at Rapyd, puts it: “My team can now categorically solve complete classes of issues, rather than just fixing the same kind of problems over and over again. This shift moves us closer to stopping threats before they turn into incidents. Moreover, it improves the general engineering quality and reduces friction with other teams.”
Blast’s launch marks a turning point. As AI accelerates everything - including attacks - the future of cloud security belongs to prevention.
Blast Security marks the end of reactive cloud security, replacing after-the-fact response with continuous prevention. Instead of reacting to threats and chasing alerts, Blast creates a living, preemptive defense fabric that continuously evolves with the enterprise cloud environment - eliminating alert fatigue, reducing operational friction, and shrinking the blast radius. The Blast founding team has worked together for more than a decade and has a proven track record of building scalable prevention products, including at Solebit (acquired by Mimecast). Headquartered in Tel Aviv, Blast is backed by leading investors and trusted by global organizations.
