Frequently asked questions

Our licenses are single user - one license is for one person.

A single license may only be installed on one system at a time. To run Sn1per Professional on multiple systems simultaneously, you'll need a license for each one.

You can, however, uninstall and re-install on a different system as needed - as long as the same license key isn't in use on two or more systems at the same time.

Every active Sn1per Professional annual plan includes professional support by email (in English).

Included: troubleshooting, installation assistance, and basic usability help for Sn1per Professional during your valid annual license term. Emails are typically answered within 24-48 business hours. We're based on the U.S. West Coast and generally respond on weekdays, excluding holidays.

Not included: we don't support unsupported operating systems or browsers (please confirm the system requirements), and we don't troubleshoot third-party software - check with the relevant vendor. We also can't provide custom scripts, code, fixes, or tutorials; our documentation, blog, and wiki cover many additional topics.

Email us at [email protected] with the following:

• Sn1per Professional version
• License key
• Operating system and version
• Browser information
• A detailed description of the problem
• Relevant screenshots

Email support is reserved for active Sn1per Professional annual licenses. For anything related to the free Community Edition, please open an issue on GitHub.

First, keep in mind that some scans simply take longer than others. If you're certain a scan is stuck, it often means the target is blocking you. You can usually get past it by running killall nmap.

Alternatively, in a separate terminal run sniper --status to list the PIDs of running Sn1per processes, then run kill -9 <PID> on the problematic process so the scan can continue.

We maintain usability in previous versions as long as possible and guarantee minimum functionality for up to 6 months from the purchase date.

Note: customer service and troubleshooting on older releases (prior to v10.0) were only supported for 14 days from the date of purchase.
