Veracode and the art of fixing what you find
Finding a software flaw is easy to celebrate. Getting it fixed is the harder business Veracode has spent two decades learning to sell.
Cycode and the art of fixing the right problem
A security alert is easy to produce and surprisingly hard to act on. Cycode has built its business around the missing connections between vulnerable code, the people who own it, and the software that actually runs.
Checkmarx Built the Scanner. Now It Wants to Kill the Security Backlog.
The 20-year-old AppSec company made its name finding vulnerable code. Its harder second act is making the findings useful before AI-assisted development turns every security queue into a landfill.
Appknox
Most security tools inspect the code developers write. Appknox follows the app that users actually touch - from compiled binary and real-device behavior to the moment a counterfeit copy appears in an app store.
MindFort
MindFort is a San Francisco AI security lab building autonomous agents that continuously find, validate, and patch vulnerabilities in web applications and APIs. Founded out of Y Combinator's X25 batch by offensive-security veterans, it runs like a 24/7 AI red team - proving exploits in isolated runtime environments before it reports them, then opening pull requests with the fix. The company raised a $3M+ seed led by Soma Capital in April 2026.
winfunc
winfunc (formerly Asterisk, YC S24) is an AI-native security engineering platform that behaves like an autonomous hacker: it finds, verifies, and patches vulnerabilities in codebases. Instead of dumping thousands of unverified SAST alerts on engineers, winfunc spins up sandboxes, writes working proof-of-concept exploits, and only reports bugs it can actually trigger - aiming for near-zero false positives. Its agent has surfaced real vulnerabilities in Node.js, React, NGINX, Supabase, Bun, Sentry, Gumroad, Anthropic's MCP SDK, and others. Founded by Mufeed VH and Vivek R, the team previously built Devika, a popular open-source AI software engineer.
Legit Security
Legit Security is an AI-native Application Security Posture Management (ASPM) company that gives security teams a single platform to discover, prioritize, and remediate risk across the entire software development lifecycle - from a developer's IDE and AI coding assistant to production. Founded in 2020 by three veterans of Israel's elite cyber units, the company consolidates fragmented AppSec findings, cuts false positives with context and reachability analysis, scans for exposed secrets, and now governs AI-generated code before it ships. Legit serves large enterprises including Google, Kraft Heinz, AIG, Freddie Mac, Cboe Global Markets, and ZoomInfo.
Mend.io
Mend.io, formerly WhiteSource, is a Boston- and Tel Aviv-based application security company that helps development and security teams find and fix vulnerabilities in open source dependencies, custom code, and AI-generated code. Its platform spans software composition analysis (SCA), static and dynamic testing (SAST/DAST), API security, automated dependency updates via Renovate, and a growing suite of AI security tools. Serving more than 1,000 customers including a quarter of the Fortune 100, Mend.io emphasizes automated remediation - producing exact code fixes rather than long lists of alerts - to help teams reduce security debt without slowing delivery.
OX Security
OX Security is an application security company that built an Active Application Security Posture Management (ASPM) platform to give development and security teams a single, code-to-cloud view of software risk. Founded in 2021 by Check Point veterans Neatsun Ziv and Lior Arzi, OX consolidates scanning across the software development lifecycle - from source code and open-source dependencies to CI/CD pipelines and cloud - then uses context and attack-path analysis to surface the roughly 5% of vulnerabilities that are actually exploitable and reachable, so teams stop drowning in alerts. The company raised a $60M Series B in May 2025 (total funding around $94-101M) with backing from DTCP, IBM, Microsoft's M12, Evolution Equity, Team8 and others.
Contrast Security
Contrast Security is a Pleasanton, California-based cybersecurity company that secures software from the inside out. Founded in 2014 by OWASP veterans Jeff Williams and Arshan Dabirsiaghi, it pioneered an instrumentation-based approach that embeds security sensors directly into running applications to detect vulnerabilities and block live attacks in real time. Its runtime security platform spans Interactive Application Security Testing (IAST), Runtime Application Self-Protection (RASP), static analysis (SAST), software composition analysis (SCA), and Application Detection and Response (ADR), serving Fortune 500 enterprises and government agencies.
Semgrep
Semgrep is a San Francisco application-security company that builds a unified AppSec platform (Code/SAST, Supply Chain/SCA, and Secrets) used by engineering teams at Dropbox, Figma, Snowflake and others. Born out of an open-source tool originally written at Facebook, it lets security teams write code-like rules and ship them through CI - cutting false positives and pushing fixes back to developers.
ZeroPath
ZeroPath is an AI-native application security platform that automatically finds and fixes software vulnerabilities. Founded in 2024 by four security and engineering veterans - including a former Google Security Engineer and a former Tesla Red Team engineer - ZeroPath replaces noisy legacy SAST tools with an LLM-powered engine that understands code semantics, verifies exploitability, and generates working patches. Within a year of launch, over 1,000 organizations trust ZeroPath to scan more than 200,000 codebases per month.
