Application security tests can be used to tell developers when they have introduced vulnerabilities into the application they’re building. Static Application Security Tests (SAST) analyze applications early in the pipeline when they are being written. Good web application security starts when the application is being developed.

Static Application Security Testing (SAST) solutions are a traditional way of addressing this. WAFs protect the network perimeter and monitor, filter, or block HTTP traffic. Compared to intrusion detection systems (IDS/IPS), WAFs are focused on the application traffic. Unfortunately, they also introduce risk. How to get started.

It was a great excuse for running a split test. By serving one version of the site with instant.page in place to some traffic, and a site without it to another, I could compare the performance of them both over the same timespan and see how it shakes out. All that was left was to see if the split testing was actually working.
