Daily expiry checks
ViewPeek inspects the live certificate every day and records how many days remain before expiration.
SSL certificate monitoring
SSL certificate monitoring before expiry becomes downtime
A certificate can renew automatically for years—until one silent failure reaches production. ViewPeek checks certificate validity and sends daily warnings throughout the final 30 days, giving your team time to fix renewal, DNS, or deployment problems.
No credit card required.

SSL monitoring included
A simple independent check for every public certificate
Monitor customer-facing websites, APIs, dashboards, authentication endpoints, and campaign domains. ViewPeek observes the certificate actually presented over the network, independently of the renewal job or hosting control panel that says it should be valid. That outside view catches the certificate visitors really receive.
Certificate visibility without calendar reminders
A full warning window
Alerts repeat daily during the final 30 days. The first warning creates room to investigate; later warnings make a stalled renewal hard to miss.
Multi-channel delivery
Notify responsible teammates by email, Slack, Discord, or webhook. Certificate alerts use the same routing options as uptime alerts.
One operational dashboard
Review SSL, uptime, ping, and sitemap monitors together instead of maintaining a separate certificate spreadsheet.
Protect a domain in three steps
You only need the public hostname; there is no certificate upload and no server agent.
-
1
Enter the domain
Add the hostname whose live TLS certificate should be checked.
-
2
Choose recipients
Select the teammates and connected channels responsible for certificate renewal.
-
3
Act during the warning window
Use the repeated final-30-day alerts to repair automation before browsers begin rejecting the connection.
Why independent SSL monitoring still matters
In ViewPeek's published aggregate dataset, all 15,177 observed certificate checks involved automated Let's Encrypt certificates. Automation worked almost all the time, yet one certificate still reached its expiry day. Monitoring verifies outcomes instead of trusting the renewal process.

Certificate monitoring is not certificate management
ViewPeek does not issue, install, or renew certificates. It independently checks the public result and warns the people or systems that can repair it. Keep automatic renewal enabled; use monitoring to verify that automation succeeds.
Frequently asked questions
When does ViewPeek warn about SSL expiry?
ViewPeek sends a daily alert throughout the final 30 days before a monitored certificate expires.
Does SSL monitoring work with Let's Encrypt?
Yes. ViewPeek checks the certificate presented by the hostname, regardless of whether it was issued by Let's Encrypt or another certificate authority.
Do I upload a private key or certificate?
No. ViewPeek connects to the public hostname and never needs your private key or certificate files.
Is SSL certificate monitoring included in the free plan?
Yes. SSL is one of the monitor types available on the Free plan, which includes up to 10 monitors in total.
