Solebit veterans raise $10M Seed for Blast Security to make prevention the new cloud standard
The platform aims to move enterprises beyond alert fatigue by testing and enforcing every change before deployment.
Blast Security, a Tel Aviv-based startup founded by veterans of Solebit and elite IDF units, announced on Monday that it has raised a $10 million Seed round co-led by 10D and MizMaa Ventures. Solebit was acquired by Mimecast in 2018 for around $100 million.
The founders, Boris Vaynberg (CEO), Ido Bukra (CPO), and Roi Panai (CTO), had the idea for Blast while on reserve duty leading a national-level cloud security project. The experience convinced them that cloud defenses must match the pace and complexity of the environments they are meant to protect, and that preventive safeguards need to be built in rather than bolted on.
Blast says its platform reduces cloud risk by more than 90 percent in production environments. The company positions its “Preemptive Cloud Defense Platform” as a departure from an industry dominated by detection tools and remediation workflows. Instead of surfacing alerts in response to misconfigurations or new code deployments, Blast converts native cloud controls into what it calls a “preventive defense fabric.” Every configuration change is modeled, tested and enforced before it can introduce risk, a form of guardrailing that, the company argues, allows organizations to secure cloud environments without slowing development.
“Cloud adoption and AI have multiplied complexity and risk faster than teams can keep up,” said Boris Vaynberg, Blast’s co-founder and CEO. “The market is full of tools for detection and remediation, but the only reliable way to mitigate risk is to prevent it in the first place.” He likened the challenge to the early days of the automobile: “Many believed horses were good enough. It’s hard to see how a new approach can redefine the standard, until it becomes the standard.”
