Website security scanning: common questions
What does a website security scanner check?
IsSafeSite checks publicly accessible website configuration, including SSL/TLS, HTTP security headers, CORS, exposed files, CMS signals and email security records. Available checks depend on the scan depth and plan. Findings help you prioritize issues for review and remediation.
Can I scan my website for free?
The Free plan includes 3 Quick scans per day and watermarked PDF reports. Pro includes 50 scans per day with Quick and Standard depths. Hunter adds Deep scans, batch scanning and white-label reports.
Does a clean scan mean my website is completely secure?
No. Automated checks cover a limited set of observable signals and can miss vulnerabilities or produce false positives. Review findings in context and combine scanning with code review, dependency updates and authorized manual testing.
What should I do after a scan finds an issue?
Review the affected URL, evidence and remediation guidance in your report. Confirm the issue, prioritize changes by severity and impact, test fixes in a staging environment, then scan again to check whether the finding has been resolved.
Which websites am I allowed to scan?
Only scan websites you own or have explicit authorization to test. Follow the site owner's testing scope and disclosure policy when reviewing or reporting findings.
