Company profile
researched Aug 2026Blast (Blast Security) is a Tel Aviv-based cybersecurity company that develops what it calls a Preemptive Cloud Defense Platform for enterprise cloud environments. Rather than surfacing alerts after misconfigurations or risky code deployments occur, the platform models, tests and enforces every cloud configuration change before it is applied, converting native cloud provider controls into a preventive guardrail layer the company describes as a "preventive defense fabric."
The company emerged from stealth in November 2025 alongside a $10 million seed round. Its stated aim is to let security teams apply preventive controls at scale without disrupting production systems or slowing development, positioning prevention as an alternative to the detection-and-remediation tooling that dominates the cloud security market.
Founding story
Blast was founded by Boris Vaynberg (CEO), Ido Bukra (CPO) and Roi Panai (CTO), who previously worked together at Solebit, a cybersecurity company acquired by Mimecast in 2018, and who served in elite Israeli Defense Force units. The founders formed the concept for Blast while on reserve duty leading a national-level cloud security project, concluding that cloud defenses must operate at the speed and complexity of cloud-native environments and that preventive safeguards need to be built into deployments rather than added afterwards.
Traction
The company reports deployment across multiple major enterprises and states that its platform prevents more than 90 percent of risk, reducing the potential impact radius of cloud misconfigurations in production environments.
Latest developments
In November 2025 Blast Security exited stealth and announced a $10 million seed round co-led by 10D and MizMaa Ventures, launching its Preemptive Cloud Defense Platform.

Market position
Blast positions itself against a cloud security market that it characterizes as saturated with detection and remediation tools, arguing that prevention is the reliable path to mitigating cloud risk as multi-cloud architectures and AI adoption increase complexity.
Technology
The platform tests, models and enforces each cloud change in advance of deployment, using native cloud controls to create a unified prevention-first security layer. Guardrails are applied to configuration changes and new code deployments so that risk is blocked before it reaches production, an approach the company contrasts with alert-driven detection and remediation workflows.
Go-to-market
Global enterprises operating multi-cloud environments, with security teams and CISOs as primary buyers. Named enterprise user Via, whose CISO Oren Hogery described using Blast to enforce preventive guardrails at scale.
Geography
Headquartered in Tel Aviv, Israel, serving global enterprise customers.
