Security guide
A free website security scanner gives developers a rapid, no-cost way to spot exposed headers, TLS issues, and common misconfiguration risks before they ship — or before an attacker finds them first.
This guide walks through a repeatable five-step scan workflow, explains how to read findings, prioritize fixes, and set up ongoing monitoring using free and low-cost tools.
Navigate to cyberlensai.com/scan and enter your site URL. No account is required. CyberLens AI checks TLS configuration, HTTP security headers, cookie settings, browser protection headers, and common launch-risk signals in seconds. Scan staging or preview URLs before production to catch misconfigurations early.
The scan returns a letter grade, a numeric score, and a findings list with severity labels. Common high-impact findings include missing HSTS, missing Content-Security-Policy, missing X-Frame-Options, weak TLS, and missing Referrer-Policy.
Most high-impact findings are HTTP headers. Add them in vercel.json, Express/Helmet, or Nginx. A single header change can resolve a Critical finding and is the lowest-cost security improvement available.
Security is not one-time. New dependencies, CDN changes, and infrastructure updates can reintroduce findings. Set up a recurring scan cadence or scheduled monitoring.
CyberLens AI free scans cover HTTPS and TLS posture, all major HTTP security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy), cookie security flags, browser protection settings, and exposed metadata signals. Paid tiers unlock AI Insights, deeper dependency checks, scan history, and scheduled monitoring.
It is a strong, fast baseline — especially for solo developers and small teams. A free scan catches the most common, easiest-to-exploit misconfiguration risks. Higher-risk applications handling payments, personal data, or authenticated sessions should also run dependency checks, manual access-control testing, and a code review before launch.
Yes. Scanning a Vercel preview URL, a staging subdomain, or any publicly reachable URL works the same as scanning a production site. Staging environments are sometimes configured differently from production — always re-scan the production URL after deploy.
Run a scan before every significant deploy, after adding third-party scripts or CDN changes, and at least once a month as a routine check. For AI-generated code workflows, scan after each major generation cycle — LLMs can omit security headers and introduce risky defaults. Scheduled monitoring on paid plans automates this cadence.
A clean scan result means your site passes the checks CyberLens AI runs — primarily configuration, headers, and TLS signals. It does not cover application-layer vulnerabilities like SQL injection, broken authentication, or business logic bugs. Use the scan as one layer of your security posture, not as a certification of full security.
