The frequency of web application vulnerability scans depends on several factors, including the criticality of the application, the size and complexity of the application, the regulatory environment, and your risk tolerance. However, a best practice is to conduct scans at least once a month for high-priority applications and quarterly for lower-priority applications. More frequent scans, such as weekly or even daily, are recommended for applications handling sensitive data or those subject to stringent regulatory compliance requirements. In addition to regular scans, consider incorporating continuous monitoring through automated tools. These tools can detect vulnerabilities in real-time and offer immediate alerts, allowing quicker response to emerging threats. For example, a financial application that processes payments should be scanned daily while a simple company blog might only need quarterly scans. The most critical factor is to ensure a process is established and adhered to, no matter what the specific frequency is. Regular security testing isn't just about finding problems; it's about establishing a consistent security posture and demonstrating due diligence. A documented vulnerability management program is essential for managing risk effectively.

Dude, scan your web apps regularly, like at least once a month. If it's a super important app, do it weekly or even daily. Don't get hacked!
