Instant SSL / TLS
Certificate Checker

Inspect SSL certificates, verify Certificate Authority trust chains, monitor expiration deadlines, and audit TLS handshake health in real time.

Security Fundamentals

Key SSL / TLS Certificate Elements

X.509 SSL certificates establish trusted encryption between user browsers and web servers. Here is how each component protects digital integrity.

Root CA Chain

Certificate Authority

The trusted cryptographic entity (e.g. Let's Encrypt, DigiCert, Cloudflare) signing and validating your server authenticity.

Validity Window

Lifecycle Expiration

Certificates have strict lifespans. Expired certificates immediately trigger full-screen browser warnings and cause ad rejections.

SAN Hostnames

Multi-Domain Coverage

Subject Alternative Names define all subdomains and aliases protected under the certificate to prevent hostname mismatch errors.

TLS 1.3 / JA3

Handshake Integrity

Modern edge handshakes negotiate zero-round-trip TLS 1.3, ensuring high-speed delivery and protecting campaigns from bot scrutiny.

TLS Handshake Security

Ad bots inspect TLS & JA3 fingerprints.
Shield your landing pages at the edge.

Modern ad network review crawlers (Meta, Google, TikTok) analyze TLS ciphers, SSL handshakes, and JA3/JA4 fingerprints to identify cloaked destinations. Cloaker.net terminates TLS at sub-15ms edge nodes, spoofing genuine browser handshakes and routing bot reviewers to compliant safe pages.

Frequently asked questions

Technical answers regarding SSL validation, automated renewal, and edge security protocols.

What does an SSL Lookup tool check?

An SSL Lookup tool inspects the active X.509 certificate on an HTTPS domain. It verifies the Certificate Authority (CA) issuer, validity window (issue and expiration dates), Subject Alternative Names (SANs), serial number, and SSL/TLS chain integrity.

Why is TLS/SSL handshake health crucial for ad campaigns and cloaking?

Ad network bots (Meta, Google, TikTok) continuously evaluate TLS handshakes and JA3/JA4 fingerprints. Slow SSL handshakes or mismatching certificate hostnames trigger immediate compliance flags and cause high landing page drop-off rates.

What are Subject Alternative Names (SANs)?

SANs are extensions in an SSL certificate that allow multiple hostnames (subdomains or distinct root domains) to be protected under a single SSL certificate.

What is the difference between SSL and TLS?

TLS (Transport Layer Security) is the modern, secure successor to deprecated SSL (Secure Sockets Layer) protocols. While the industry still colloquially uses the term 'SSL', modern web infrastructure exclusively deploys TLS 1.2 and TLS 1.3 encryption.
