WAF Alone Cannot Fully Protect Websites and APIs, Managers Warn

A Web Application Firewall inspects HTTP/HTTPS traffic against defined rules and can block or log suspicious requests, but it is not a complete defense. It cannot fix underlying software vulnerabilities, although it can apply temporary virtual patches that must be paired with permanent code fixes. Attacks that abuse legitimate logins and API calls, such as authorization flaws or automated misuse of business processes, can look normal to a WAF and are harder to detect. The article stresses that WAFs require ongoing rule tuning, log monitoring, and coverage checks, and that security should be treated as a continuing management responsibility with assigned budget, owners, and deadlines.
