ProjectDiscovery (Nuclei)
ProjectDiscovery (Nuclei) is an open-source, template-driven vulnerability scanning engine that is used in attack surface management to discover exposed assets, identify internet-facing services, and detect weaknesses across web applications, APIs, DNS, cloud infrastructure, and networks. In the ASM scope, it is strongest as a scanner and validation layer rather than a broad asset inventory platform, giving security teams attacker-style visibility into exposed hosts and services. It is a fit for practitioners who want programmable, repeatable scanning with a large community template ecosystem and minimal vendor lock-in. ProjectDiscovery also offers adjacent SaaS and agentic products, but Nuclei itself remains the core scanning engine.
