Frequently Asked Questions
Is CyberArsenal's website scanner free?
Yes. You can run up to 3 free scans per day. PRO users get unlimited scans, full history, and PDF reports.
What does the website security scanner check?
It analyzes SSL/TLS configuration, HTTP security headers, technology stack, DNS records, and common misconfigurations that could expose your site to attacks.
Is it safe to scan my own website?
Absolutely. The scanner only performs passive analysis — it reads publicly available information like headers, certificates, and DNS records. It does not attempt any exploitation.
Can I scan someone else's website?
You should only scan websites you own or have explicit permission to test. Unauthorized scanning may violate terms of service or local laws.
How often should I scan my website?
We recommend scanning after every deployment, and at least weekly for production sites. SSL certificates, headers, and dependencies can change without notice.
For authorized, legal, and ethical security testing only. Scans are rate-limited to 3 per day on the free tier.
