RASP capabilities aim to close the gap left by application security testing and network perimeter controls such as web application firewalls (WAFs). A centralized approach to WAF uses a single firewall to protect many application servers against large-scale distributed attacks. This reduces false positives in your DevSecOps process.

Using a connection pool in each module is hardly efficient: Even with a relatively small number of modules, and a small pool size in each, you end up with a lot of server processes.
