There’s really only one way to reliably protect internal and external applications, whether they’re deployed on-premises or in the cloud, and that’s a WAF.
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.
One way to protect against introducing new code vulnerabilities is to have a WAF policy integrated with development. That way, you can have an agile development environment without weakening your security posture.
Tuning and keeping security policies current typically means some degree of reliance on your WAF vendor and third-party help. At F5, we have research groups focused on studying emerging attack vectors to help make sure you’re protected against the latest web application threats.
F5 gives you WAF options recognized by independent analysts for their power and value. With F5’s application focus, Layer 7 protection expertise, bot detection and behavioral analysis capabilities, you get the power and flexibility to cover a broader range of threats.
With compliance, integrations, and dynamic learning, F5’s WAF also offers you choices from self-managed to fully managed and a range of deployment options from on-premises to private and public cloud, so you can choose the best match for your business.
