About SSL Bulk Checker
The CSR.plus Bulk SSL Checker lets you validate the certificates of many domains at once. Paste a list of hostnames, one per line, and get a consolidated view of expiry dates, issuers, and days remaining so you can plan renewals across your entire fleet from a single screen.
Companies with dozens or hundreds of domains rarely review them one by one — that is how certificates slip through the cracks. This batch SSL checker aggregates the status of every host you paste, marks expired and expiring certificates at a glance, and lets you export the results to CSV for renewal planning and audit records.
Why use
- Check multiple SSL certificates in one batch, one host per line
- Spot expired and expiring certificates across your whole fleet
- Export consolidated results to CSV for planning and audits
- Live checks in your browser session — no data is stored
How to use
- Paste one hostname per line into the input box.
- Click check — the tool probes each domain and collects its certificate details.
- Review the combined table of expiry, issuer, and remaining days for every host.
- Export the results to CSV or fix the flagged domains directly.
Frequently asked questions
▸How many domains can I check at once?
You can paste a long list; results are aggregated so you can scan an entire portfolio quickly.
▸Is the data stored?
No. Checks run live in your browser session and nothing is persisted on a server.
▸What if a domain has no HTTPS?
The result flags the host as unreachable or without a valid certificate so you can investigate.
▸Why use a bulk SSL checker instead of checking domains one by one?
A bulk checker gives you a single consolidated view of expiry dates and issues across many domains, which is the fastest way to plan renewals and avoid missed certificates.
