# Bulk website checks

> Paste a list of domains and get SSL, uptime, DNS and header results for all of them in one pass — the fastest way to audit a portfolio.

## Check a whole portfolio at once

 The single-shot tools handle one domain at a time. Bulk mode takes a list and runs the same check across every entry, returning one row per domain so you can scan a portfolio for the outlier instead of clicking through one at a time.

## What it's good for

 Auditing certificate expiry across a client list before renewal season, spotting which sites are missing security headers, and finding domains with DNS or email authentication gaps. Results sort worst-first so the problems surface at the top.

## Limits

 Bulk runs are capped per batch and rate-limited to keep them fair, and every result is a point-in-time snapshot. To have the same checks run continuously and alert when something changes, add the domains as monitored sites instead.
