Enter any domain and get a comprehensive security assessment in under 30 seconds. 19 parallel checks cover SSL, headers, exposed files, DNS, reputation, and more.
19 parallel checks. Built by a CEH-certified security engineer with 10+ years experience.
Every scan runs 19 parallel security checks across your entire domain surface. Here is what we look for.
Validates certificate chain, expiration, cipher suites, and protocol versions. Flags weak configurations and mixed content.
Checks for HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
Probes for .env files, .git directories, backup files, config files, database dumps, and debug endpoints.
Analyzes SPF, DKIM, DMARC records for email authentication. Checks for dangling CNAMEs and zone transfer risks.
Checks major blacklists and reputation databases. Flags domains that appear on spam or malware blocklists.
Identifies CMS platforms, web servers, frameworks, and versions. Flags outdated software with known CVEs.
Every website has an attack surface. SSL misconfigurations, missing security headers, exposed configuration files, weak DNS records: these are the low-hanging fruit that automated bots scan for millions of times per day. The average website receives 94 attacks per day according to SiteLock's annual report, and most of these are automated scripts probing for known weaknesses.
The cost of ignoring these vulnerabilities is significant. IBM's 2025 Cost of a Data Breach Report puts the average breach cost at $4.88 million. For small and mid-size businesses, a single compromised server can mean weeks of downtime, customer notification costs, regulatory fines, and permanent reputation damage. A domain security scan takes 30 seconds and costs nothing. A breach takes months to recover from.
Regular scanning is also increasingly a compliance requirement. PCI DSS mandates quarterly vulnerability scans for any site handling payment data. SOC 2, HIPAA, and GDPR all require demonstrable security controls. Running automated scans and documenting the results is one of the easiest ways to meet these requirements.
A comprehensive domain security scan examines multiple layers of your web infrastructure. Here is what each category of checks looks for and why it matters:
Your SSL certificate is the foundation of transport security. The scan validates that your certificate is issued by a trusted authority, has not expired, uses strong cipher suites, and supports modern TLS versions (1.2 and 1.3). It also checks for HTTP-to-HTTPS redirection and mixed content issues. A misconfigured SSL setup means data transmitted between your users and your server can be intercepted. Use our SSL Checker for deeper certificate chain analysis.
HTTP security headers instruct browsers on how to handle your content securely. Missing headers leave users vulnerable to clickjacking, cross-site scripting, MIME sniffing, and other client-side attacks. The scan checks for six critical headers: Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. Over 90% of websites are missing at least one of these. Use our CSP Builder to generate a proper Content Security Policy.
Many breaches begin with a misconfigured web server that serves files that should never be public. The scan probes for .env files containing credentials, .git/ directories exposing source code, backup files (.bak, .old, .swp) with configuration data, phpinfo.php pages revealing server details, and database dumps left in web-accessible directories. Even a single exposed .env file can hand an attacker your database credentials, API keys, and encryption secrets.
Weak DNS configuration enables email spoofing, subdomain takeover, and information disclosure. The scan checks for SPF records (which servers can send email for your domain), DKIM records (email signature verification), and DMARC records (what to do with failed email authentication). Missing these records means anyone can send email that appears to come from your domain, which is the foundation of most phishing attacks. Use our DNS Lookup for detailed record analysis.
Knowing which software versions your server runs helps identify known vulnerabilities. The scan detects CMS platforms (WordPress, Magento, Drupal), web servers (Apache, Nginx, IIS), programming languages, and JavaScript frameworks. Outdated software with published CVEs is one of the primary attack vectors used in automated scanning campaigns. If you are running WordPress 5.x when 6.x is current, every known vulnerability in the older version becomes an open door.
If your domain appears on spam blacklists or malware blocklists, your emails will not be delivered and search engines may flag your site as dangerous. The scan checks major reputation databases including Spamhaus, SURBL, and Google Safe Browsing. A poor reputation score often indicates a previous compromise that may not have been fully remediated.
After scanning thousands of domains, certain patterns appear consistently:
Once you have your scan results, follow this hardening checklist:
.env, .git, backup files) at the web server levelThe scan runs 19 parallel checks covering SSL/TLS configuration, security headers (HSTS, CSP, X-Frame-Options, etc.), exposed sensitive files (.env, .git, config files, backups), DNS records (SPF, DKIM, DMARC), domain reputation across major blacklists, and technology fingerprinting to detect outdated software with known vulnerabilities.
Yes. The scanner uses passive, non-intrusive techniques only. It reads publicly available information (HTTP headers, DNS records, SSL certificates) and checks if known sensitive paths are accessible. It does not inject payloads, attempt authentication, modify data, or perform any active exploitation. It will not trigger WAF rules or cause any disruption to your site.
Most free scanners focus on a single area (SSL Labs for SSL only, SecurityHeaders.com for headers only). SecureBin runs 19 checks across SSL, headers, exposed files, DNS, reputation, and technology detection in a single scan. You get a comprehensive overview in 30 seconds instead of running five separate tools. Results include severity ratings and specific remediation steps.
Scan after every deployment, after infrastructure changes (DNS updates, certificate renewals, server migrations), and at minimum once per week. If you handle payment data (PCI DSS) or health data (HIPAA), more frequent scanning may be required. The scan is free and takes seconds, so there is no reason not to scan regularly.
