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.
