Frequently asked questions

What happens when an SSL certificate expires?

Browsers block visitors with a security warning, traffic drops, and your client loses trust in your agency. Search engines may also de-rank the site. A single expired cert can cost more than a year of monitoring.

How often should I check SSL certificates?

At minimum, check monthly — but the best practice is automated continuous monitoring with alerts at 30 days and 7 days before expiry. That gives you time to renew without rushing.

Is this SSL checker free?

Yes, completely free with no account required. For automated monitoring across all your client domains with email and Slack alerts, sign up for Vizze free.

Why do agencies need SSL certificate management?

Agencies manage dozens or hundreds of client domains across different registrars, hosts, and teams. There's no single place that owns the cert inventory — until Vizze. One dashboard, every cert, every client.
