The Story

A company built to end the whack-a-mole

Every company today ships software, and every line of that software is potential attack surface. Legit Security was founded in 2020 on a blunt premise: the tools meant to secure that software had become part of the problem. Security teams were drowning in a dozen disconnected scanners, each firing alerts with no shared context - a game of whack-a-mole where fixing one issue surfaced three more. The three founders, Roni Fuchs, Liav Caspi, and Lior Barak, had lived that frustration from the inside, having led product and engineering at Checkmarx after serving together in the cyber-warfare division of the Israel Defense Forces.

Their answer was Application Security Posture Management, or ASPM: instead of another scanner, a platform that sits above them all - discovering every asset from a developer's laptop to production, unifying findings into a single view, and ranking risk by what is actually reachable and exploitable. The goal is not more alerts. It is fewer, better ones, with a clear path to remediation. Today that platform guards software at Google, Kraft Heinz, AIG, Freddie Mac, Cboe Global Markets, and the New York Stock Exchange.

"When AI writes the code, Legit secures it."

- Legit Security, on the launch of VibeGuard, 2025
What It Does & Why

The problems it solves

The problem

  • Findings scattered across SAST, SCA, secrets, and pipeline tools that never talk to each other
  • Alert overload with no way to tell a real threat from noise
  • Secrets leaking into Git history, build logs, and shared workspaces
  • Over-privileged, insecure CI/CD pipelines as a soft supply-chain target
  • AI coding agents now writing bugs and pulling risky dependencies at machine speed

The Legit approach

  • One posture platform that consolidates every AppSec finding into a single score
  • Context and reachability analysis to prioritize what is actually exploitable
  • AI-powered secrets detection across the full development pipeline
  • Code-to-cloud visibility that maps risk end to end
  • Guardrails inside the IDE that govern AI-generated code before it ships
