Scan first. Then see what's safe to block.
Is your website exposed? Run a free, instant security scan. We check whether your site sits behind a firewall, what security headers it sets, your TLS, and whether your server software is leaking. No signup, no agent to install. Paste your URL. After the scan, start a 14-day trial with this domain already filled in.
