An SSL checker verifies whether your website's SSL/TLS certificate is correctly installed, valid, and trusted by browsers. Over 85% of websites now use HTTPS encryption, yet misconfigured certificates cause security warnings that drive visitors away. ToolsPivot's SSL Checker instantly scans your domain to detect certificate errors, expiration dates, and chain issues before they affect your users.
ToolsPivot's SSL Checker connects to your web server and retrieves complete certificate information within seconds. The tool examines certificate validity, issuer details, expiration dates, and the entire certificate chain to identify installation problems. It supports all major certificate types including DV, OV, and EV certificates across any hosting environment.
Website administrators, developers, and IT security professionals use SSL checkers to verify certificate deployments after installation. E-commerce site owners check their SSL status to maintain PCI DSS compliance and customer trust. Digital marketers monitor SSL health because Google ranks HTTPS sites higher in search results.
Expired or misconfigured SSL certificates display browser warnings that cause 98% of visitors to leave immediately. ToolsPivot's SSL Checker identifies certificate problems before they impact your traffic, showing exactly which issues need fixing and providing actionable guidance for resolution.

The tool establishes a secure connection to your server on port 443 to retrieve certificate data.
Certificate information including issuer, validity period, and chain details are extracted and analyzed.
The system validates the certificate against browser trust stores and checks for known vulnerabilities.
Results display showing certificate status, any errors found, and specific recommendations for fixes.
Use an SSL checker immediately after installing any new certificate to confirm proper configuration. Regular monthly checks catch expiration issues and security vulnerabilities before they affect users.
After Certificate Installation Verify new SSL certificates are correctly configured before directing production traffic to your server.
Before Certificate Expiration Check remaining validity days monthly to ensure timely renewals and avoid service interruptions.
After Server Migration Confirm SSL settings transferred correctly when moving websites to new hosting environments.
Troubleshooting Browser Warnings Diagnose "Not Secure" or certificate error messages reported by users visiting your site.
Security Compliance Audits Generate SSL reports for PCI DSS, HIPAA, or SOC 2 compliance documentation requirements.
Multi-Domain Verification Check SSL status across all domains and subdomains in your portfolio using the domain availability checker.
Client Website Monitoring Agencies use SSL checkers to monitor client sites and proactively address certificate issues.
Edge cases include checking SSL on non-standard ports or verifying certificates on internal network servers that may require different tools.

API Endpoint Security
SSL certificates come in three validation levels based on the identity verification performed by the Certificate Authority.
Domain Validation (DV) DV certificates verify domain ownership only through email or DNS record confirmation. Issuance takes minutes and costs are lowest among certificate types. Suitable for blogs, personal sites, and basic HTTPS encryption needs.
Organization Validation (OV) OV certificates verify both domain ownership and organization identity through business documentation. The issuing CA confirms the company exists and owns the domain. Recommended for business websites, intranets, and applications handling user data.
Extended Validation (EV) EV certificates require thorough verification including legal entity confirmation, physical address verification, and operational status checks. These certificates previously displayed green address bars and provide highest trust levels for financial sites and enterprises.
Wildcard Certificates Wildcard certificates secure a domain and all its subdomains using a single certificate (*.example.com). Check wildcard coverage using ToolsPivot's DNS lookup to verify subdomain configuration.
Certificate Not Trusted The certificate wasn't issued by a CA in browser trust stores. Usually indicates self-signed certificates or missing intermediate certificates.
Certificate Expired The certificate's validity period has passed. Renew immediately to restore secure connections and visitor trust.
Hostname Mismatch The certificate was issued for a different domain than the one being accessed. Verify correct certificate installation for each domain.
Incomplete Certificate Chain Intermediate certificates weren't installed on the server. Browsers cannot verify trust without the complete chain from root to server certificate.
Mixed Content HTTPS page loads resources over HTTP. While not a certificate error, this triggers browser warnings. Use page speed checker to identify HTTP resources.
Protocol or Cipher Issues Server supports only deprecated protocols or weak ciphers. Update server configuration to support TLS 1.2+ and strong cipher suites.
Complete your website security workflow with these complementary ToolsPivot tools:
An SSL checker connects to your website's server and analyzes the installed certificate to verify it's valid, properly configured, and trusted by browsers. The tool displays certificate details including issuer, expiration date, and any configuration errors that need attention.
Check your SSL certificate monthly at minimum, and always after server changes or certificate renewals. Set calendar reminders for 30 days before expiration to ensure sufficient time for renewal.
Untrusted certificates typically result from missing intermediate certificates, self-signed certificates, or expired validity periods. ToolsPivot's SSL Checker identifies the specific cause so you can apply the correct fix.
A certificate chain links your server certificate through intermediate certificates to a trusted root CA. Missing intermediates cause trust failures in some browsers even when your certificate is valid. Use CSR decoder to verify certificate details before installation.
Yes, you can check the SSL certificate of any publicly accessible website by entering its domain name. The tool connects to public port 443 and retrieves certificate information visible to any browser.
Modern servers should support TLS 1.2 and TLS 1.3 while disabling older protocols like SSL 3.0 and TLS 1.0/1.1. Our SSL checker identifies which protocols your server currently accepts.
Ensure the certificate's Common Name or Subject Alternative Names include the exact domain being accessed. Request a new certificate with correct domain names if the current certificate doesn't match.
Browsers display security warnings preventing most visitors from accessing your site. Expired certificates must be renewed and reinstalled to restore secure connections. Use server status checker to monitor availability after renewal.
Yes, Google confirmed HTTPS as a ranking signal. Sites with valid SSL certificates may rank higher than HTTP equivalents. Use meta tags analyzer to verify your site's SEO configuration alongside SSL.
Enter your domain in ToolsPivot's SSL Checker to see the exact expiration date and days remaining. The tool displays validity period prominently in the results for easy monitoring.
OCSP stapling allows your server to provide certificate revocation status directly instead of browsers querying the CA. This improves page load speed and privacy while maintaining security verification.
Yes, the SSL checker verifies wildcard certificates and displays the covered domains (*.example.com format). Check individual subdomains to confirm they resolve correctly to servers with the wildcard certificate installed.
Mixed content warnings occur when HTTPS pages load images, scripts, or other resources over HTTP. The certificate is valid but the page references insecure content. Use code to text ratio checker to analyze page structure.
