No application is bulletproof.

WAFs are borne out of the desire to keep security close to the app to protect against cyber threats to your data and ensure constant app integrity and availability—whether in the data center or in the cloud.

Standing up a WAF in front of a legacy app to mitigate vulnerabilities like cross-site scripting, SQL injection attacks, and sensitive data exposure is often a better route to securing code and meeting compliance standards such as PCI-DSS than actually fixing the code. Plus, it gives security operations teams breathing room to put long-term measures in place.

F5 positioned as a Leader in 2017 Gartner Magic Quadrant for Web Application Firewalls.
