Frequently Asked Questions

Is OWASP ZAP better than StackShield because it is free?

They solve different problems. ZAP performs deep, point-in-time active scanning. StackShield provides continuous external monitoring with instant alerts. ZAP tells you what is vulnerable right now. StackShield tells you when something changes. Most teams benefit from using both.

Can I use OWASP ZAP and StackShield together?

Yes, and this is the recommended approach. Use ZAP for periodic deep scans (especially before major releases), and use StackShield for continuous monitoring between scans. ZAP catches vulnerabilities that require active testing. StackShield catches configuration drift and exposed tools that appear between scans.

Does StackShield do active vulnerability scanning like ZAP?

No. StackShield performs non-invasive external monitoring. It checks what is visible from the outside without sending malicious payloads. ZAP actively tests for vulnerabilities by sending crafted requests. StackShield is safe to run continuously against production. ZAP should be used against staging or with caution in production.
