With the increasing number of web application security breaches, it is essential to keep your web application secure at all times. Furthermore having security integrated into your CI/CD pipeline (DevSecOps) will become a lifesaver if you are actively developing the application.

Some vulnerabilities can only be found by sending payloads that cause a callback to the tester. One example is XXE vulnerabilities when the XML rendering result is not available to the user. ZAP can find these vulnerabilities that depend on SSRF detection but the target system needs to be able to reach the ZAP callback endpoint.

At OWASP AppSec EU in Amsterdam this year I announced ZAP as a Service (ZaaS).
The slides are here and the video will hopefully be available soon.
The idea behind this development is to enhance ZAP so that it can be run in a ‘server’ mode.
This is different to the current ‘daemon’ mode in that it will be designed to be a long running, highly scalable, distributed service accessed by multiple users with different roles.
