Web security should be effortless.
TLS Radar gives teams a clear, reliable view of every certificate they own — so a missed renewal never costs a sale, a customer, or a night of sleep.
Our mission
Make certificate failures a thing of the past.
Every day, millions of websites depend on TLS certificates to establish trust and secure communication. But a single expired or misconfigured certificate can break that trust instantly — locking out users, damaging reputation, and stalling revenue.
TLS Radar exists to prevent that. We help developers, IT teams, and business owners keep their sites secure, compliant, and always reachable — without the cost or complexity of legacy enterprise tools.
What we watch for
Continuous, external monitoring across every endpoint you own.
Certificate expiration
Tiered alerts at 30, 14, 7, 3, and 1 day before expiry — across all your domains.
Configuration issues
Detect broken chains, hostname mismatches, and misconfigurations that trigger browser warnings.
Known vulnerabilities
Catch weak ciphers, deprecated protocols, and CVEs before attackers — or auditors — do.
Reachability & uptime
Confirm endpoints respond correctly and aren't silently failing in production.
Why TLS Radar
Built deliberately differently from the legacy enterprise tools.
Honest pricing
Enterprise-grade monitoring without enterprise sticker shock. Free forever for small teams.
No agents, no servers
Get started in minutes. Nothing to install, nothing to maintain — just add domains and go.
Built for humans
Clear status, actionable alerts, no jargon. Your developers and your CFO can both read it.
Team-first by design
Multi-team workspaces, role-based access, and shared visibility from day one.
Open and integrated
Email, Slack, webhooks, and a REST API. We fit into your stack — not the other way around.
Independent
No certificate vendor agenda. We work for you, not for whoever issued your cert.
Why now
Certificate management is getting harder, not easier.
Certificate lifespans are shrinking — from 13 months, to 6 months, to 90 days, and soon less. Web infrastructure is expanding faster than ever, and AI-assisted development is shipping code at a pace operations teams have never had to support before.
The old playbook — a spreadsheet, a calendar reminder, and hope — doesn't scale anymore. TLS Radar is what comes next: continuous, automated, transparent monitoring that just works.
