NAXSI means Nginx Anti XSS & SQL Injection. Technically, it is a third party nginx module, available as a package for many UNIX-like platforms. This module, by default, reads a small subset of simple (and readable) rules containing 99% of known patterns involved in website vulnerabilities. For example, <, | or drop are not allowed. It's a powerful tool to prevent common web attacks.
