What are the potential downsides or limitations of using a WAF?

While WAFs offer significant benefits in protecting web applications, they have some limitations. One potential downside is the possibility of false positives, where the WAF mistakenly blocks legitimate traffic, which can disrupt user experience and business operations. Additionally, WAFs can introduce latency, affecting the performance of web applications if not properly configured. Finally, WAFs require ongoing management and tuning to remain effective, which can be resource-intensive for organizations without a dedicated security team.
