Meterian is a UK-based cybersecurity company, headquartered in London, that specializes in open source security for software development workflows. The company operates in the application security testing (AST) space, offering a cloud-based, automated SaaS platform designed to help developers and DevSecOps teams identify and remediate vulnerabilities in open source dependencies. Meterian's platform integrates into the software development lifecycle (SDLC), enabling organizations to scan their codebases for known vulnerabilities in third-party and open source components. The tooling is designed to be flexible and adaptable, allowing teams to configure it to match their existing development workflows rather than requiring process changes to accommodate the tool. The company targets enterprise customers and development teams looking to shift security left by embedding vulnerability detection earlier in the software delivery pipeline. Meterian emphasizes a lean, DevSecOps-oriented approach, aiming to reduce complexity and implementation cost while integrating with external services and custom tooling where needed. The platform supports a broad range of programming languages and package ecosystems, and is designed to run anywhere — including CI/CD pipelines. Meterian positions its product as accessible and affordable for organizations of varying sizes, deliberately avoiding niche or overly specialized features in order to keep the solution streamlined. The company is a small, growing B2B SaaS business actively hiring in the cybersecurity space.
