How to: Our Mission
Traditional vulnerability scanners were built decades ago. They are closed-source, incredibly slow, and vendor-driven. Today's attackers are mass exploiting newly released CVEs across the internet within days, unlike the years it used to take. This shift requires a completely different approach to tackling trending exploits on the internet.

We built Nuclei to solve this challenge. We made the entire scanning engine framework open and customizable—allowing the global security community to collaborate and tackle the trending attack vectors and vulnerabilities on the internet. Nuclei is now used and contributed by Fortune 500 enterprises, government agencies, universities.
