Radar by ManugNothing your clients rely on expires by surprise.
Radar tracks every TLS certificate, domain registration and license renewal across the clients you manage, then alerts you in email, Slack, Discord or Telegram before anything lapses.
Certificate lifetimes are shrinking. Renewals are about to happen 8× more often.
The CA/Browser Forum is cutting the maximum life of public certificates in stages. Anything renewed by hand, by a fixed cron job, or by a vendor you forgot about will start failing.
Maximum certificate lifetime (was 398).
Let's Encrypt default. Fixed 60-day renewal jobs break.
Maximum lifetime for every public CA.
Final step. Manual renewal stops being realistic.
One calm list instead of spreadsheets and calendar reminders.
Find every certificate
Type a domain and Radar pulls every hostname with a live certificate from public Certificate Transparency logs, including the ones nobody remembers.
Daily TLS checks
We connect to each host every day, read the certificate it actually serves, and flag broken chains and hostname mismatches, not just expiry.
Domain registrations
Registry expiry dates come straight from RDAP, so a lapsed card on a registrar account never takes a client's site offline.
Licenses & warranties
Add any renewal with a date: Microsoft 365 seats, firewall licenses, hardware warranties, support contracts. Same alerts, same list.
2027 readiness
Radar studies each host's renewal history and warns you when it renews on a fixed ~60-day cycle that 64-day certificates will break.
Per-client reports
Group items by client and print a clean renewal report for your monthly check-in or a hand-over to a new provider.
Good to know
Do you need access to my servers or DNS?
No. Radar only reads public information: the certificate a server presents, public Certificate Transparency logs and registry RDAP records. Licenses and warranties are dates you type in.
Who is Radar for?
Small IT teams, managed service providers and web agencies who look after many sites and renewals for many clients, and are tired of spreadsheets.
How do alerts work?
You get one alert at 30, 14, 7, 3 and 1 days before expiry, then a daily reminder inside the last week until someone acknowledges it. Alerts go to email, Slack, Discord, Telegram or any webhook.
Can it check mail servers or custom ports?
Yes. Add any host:port that speaks TLS directly, for example mail.example.com:465 or vpn.example.com:8443.
What does it cost?
Radar is free while in early access. Paid plans start at $19/month for teams. See pricing.
