Quick answer

A website vulnerability scanner probes a site for security weaknesses and reports what an attacker could find. Secably's free quick scan checks SSL, DNS, security headers, and exposed files in seconds; the Pro deep scan actively tests for OWASP Top 10 flaws like SQL injection, XSS, and SSRF. Scan any site you own or are authorized to test.

  • Quick scan: SSL, DNS, headers, exposed files
  • Deep scan (Pro): OWASP Top 10 testing
  • Findings ranked by severity with fixes
  • Free quick scan, no signup required

What is a website vulnerability scanner?

A website vulnerability scanner automates the reconnaissance an attacker would do by hand: it inspects how your site is configured and, in a deep scan, probes its inputs for exploitable flaws. Instead of waiting to discover a weakness after a breach, you find and fix it on your own schedule.

Secably splits this into two levels. The quick scan is passive and instant — it reads your security configuration without touching application logic. The deep scan is active: it crawls the site, finds forms and parameters, and safely tests each one for injection and related vulnerabilities.

What the OWASP Top 10 covers

The OWASP Top 10 is the industry-standard list of the most critical web application risks. In its 2021 edition, Broken Access Control ranks first and Injection — which includes SQL injection and cross-site scripting — ranks third. A scanner that maps its findings to this list gives you a shared, prioritized language for what to fix and in what order.

How a website scan works

Secably runs configuration checks in every scan, adds active vulnerability testing in a deep scan, and presents everything ranked by severity.

— Quick

Configuration checks

Inspects SSL/TLS, DNS security (SPF, DMARC, DKIM), HTTP headers, CORS, and exposed sensitive files — a passive pass in seconds.

— Deep · Pro

Active OWASP testing

Crawls the site, discovers forms and parameters, and tests each for SQL injection, XSS, SSRF, CSRF, path traversal, and more.

— Report

Severity & remediation

Groups findings by severity, maps them to the OWASP Top 10, and gives a concrete fix for each so you know what to tackle first.

How to scan a website in 3 steps

1

Enter your URL

Type the URL of a site you own or are authorized to test, like https://example.com.

2

Run the scan

Run a free quick scan of your configuration, or a Pro deep scan for active OWASP Top 10 testing.

3

Fix by severity

Work through findings ranked by severity, apply the recommended fixes, and re-scan to confirm they're resolved.

Only scan what you're allowed to. Run Secably against sites you own or have explicit written authorization to test. Unauthorized vulnerability scanning is illegal in most jurisdictions.

Who uses a website scanner

dev
Catch flaws before you ship
Developers: scan staging and production to catch injection points and misconfigurations before an attacker does.
ops
Keep configuration hardened
Sysadmins & ops: monitor SSL, DNS, and headers across sites and get alerted when a deploy weakens the baseline.
sec
Run repeatable OWASP checks
Security teams: run deep scans mapped to the OWASP Top 10 and produce severity-ranked evidence for audits and clients.

Frequently Asked Questions

What does this scanner check for? +
The free quick scan checks SSL/TLS configuration, DNS security (SPF, DMARC, DKIM), security headers, CORS misconfiguration, and exposed sensitive files. The Pro deep scan adds full OWASP Top 10 testing: SQL injection, XSS, SSRF, CSRF, path traversal, and more.
What's the difference between Quick and Deep scan? +
A quick scan runs in about 15 seconds and checks your security configuration — SSL, DNS, headers, exposed files. A deep scan (Pro) takes a few minutes: it crawls the site, discovers forms and parameters, then tests each one for SQL injection, XSS, SSRF, command injection, and other OWASP Top 10 vulnerabilities.
Should I only scan my own websites? +
Yes. Only scan websites you own or have explicit written authorization to test. Unauthorized vulnerability scanning is illegal in most jurisdictions.
Is the website scanner free? +
Yes. The quick scan is free with no signup. A free account saves your reports; Pro plans unlock the deep OWASP Top 10 scan, scheduled monitoring, and API access.
