Security Scanning Tools FAQ
Common questions about Security Scanning tools, selection guides, pricing, and comparisons.
Scan frequency depends on asset criticality and change rate: internet-facing assets should be scanned continuously or daily, internal critical systems weekly, and all other systems at least monthly. Additionally, run scans after any significant infrastructure changes, new deployments, or when critical CVEs are published. Compliance frameworks like PCI DSS require at least quarterly external scans.
