At the bottom of this page you’ll find the scan button and terms of service that you must agree to before we conduct the test. Why do we require you to agree to these terms? This is a free security scan and we take every measure to make sure we are providing a valuable and welcome service. There are times that a visitor may attempt to perform a security scan on a computer that they are not authorized to audit, such as a work pc inside a company network.
NOTE: THIS SECURITY SCAN is Down for Maintenance, Please use our Firewall Test which performs the same scan.
When a security scan is performed on such a pc, often times, our free service appears to be an attack on the company network. By requiring visitors to enter a captcha and agree that they have read our TOS before auditing networks, we reduce and often eliminate unnecessary mistakes.
Once you have agreed, you will be able to perform your selected security scan.
This security scan was the first free full security scan on the internet! There were other security scanning services but they were limited and only by purchasing a ‘security scan package’ could you perform a full security scan. It was for this very reason we created this free security scanning service!
Please note that your log files will show an audit originating from (220.127.116.11). Some firewalls permanently block an IP address if it detects a scan, so you’ll want to temporarily disable this autoblock feature (not the firewall) or you may receive incorrect results.
Please enter the ports you would like scanned. We currently allow up to 2000 TCP ports and 2000 UDP ports to be scanned in one session. You can leave one of the port fields blank to scan only TCP or UDP ports.
