TLS works like a secure envelope for information traveling across the internet. When visitors access your website using HTTPS, TLS creates an encrypted connection that protects their data and verifies your site's identity.

Without proper TLS protection, your website is vulnerable to:

We monitor these critical aspects of your TLS configuration:

The domain's SSL certificate is invalid, expired, or not issued by a trusted authority. This prevents secure connections and may cause browsers to show security warnings to visitors.

The domain's SSL certificate chain is incomplete or contains untrusted certificates. This can cause connection errors and security warnings in some browsers.

The domain uses outdated SSL/TLS versions (SSL 2.0, SSL 3.0, TLS 1.0, or TLS 1.1). These older versions have known security vulnerabilities that attackers can exploit.

The SSL certificate's hostname doesn't match the domain name. This mismatch triggers security warnings and may indicate a misconfiguration or potential security issue.

The domain's SSL certificate chain is missing intermediate certificates. This causes validation failures in some clients, preventing secure connections.

The domain's SSL certificate is valid for more than 13 months. This exceeds industry standards and increases the window of exposure if the certificate is compromised.

The domain's certificate is not logged in Certificate Transparency logs. This reduces the ability to detect potentially malicious certificates issued for the domain.

The domain lacks Certificate Authority Authorization records in DNS. This allows any certificate authority to issue certificates for the domain.

The domain doesn't support Server Name Indication (SNI). This limits the ability to serve multiple secure sites from the same IP address.
