About ProjectDiscovery

Software ships daily. Security testing happens quarterly, or once a year. Everything in between goes untested, and the gap widens as AI agents write a growing share of the code. From the founders of popular open source tools like Nuclei, httpx, subfinder and more, Neo is ProjectDiscovery's unified offensive testing and regression platform for vulnerability management. One engine pentests code, web apps, APIs, networks, and cloud on every PR and release, validates what is exploitable, and enforces every fix as a permanent regression test. In a head-to-head benchmark against DAST scanners and AI security tools, Neo found 24 exploitable vulnerabilities no other tool caught, with the lowest false positive rate of anything tested. Security compounds release over release. Trusted by teams at Elastic, Vercel, and thousands more, ProjectDiscovery brings open-source flexibility to enterprise workflows, enabling full visibility and faster remediation in minutes with zero setup friction.
