Filters let you hide values you don’t care about from your results. You choose a field, such as Emails or Domains, and enter a regex pattern. Any value in that field that matches the pattern is hidden when you open the matching section in Jsmon. Use filters to remove placeholder data, third-party services and other noise that shows up in almost every scan, so the findings that matter are easier to spot.
Filters only change what you see. Your scan data is not deleted, and turning a filter off brings the hidden values back right away.

​
How Filters Work

Each filter has three parts: A field can have more than one filter. A value is hidden if it matches any enabled filter for its field.

​
Supported Fields

The Field dropdown on the Filters page lists every field you can filter.

​
Creating a Filter

1. Open Filters Select Filters in the left sidebar. 2. Choose a field In Create a filter, pick the field you want to filter from the Field dropdown. 3. Enter a regex pattern Type your pattern in Regex Pattern. Use | to match several values in one filter, for example example\.com|mail\.com|test\.com. 4. Choose where it applies Select This workspace or All workspaces under Applies To. 5. Add the filter Click Add filter. The filter is enabled straight away and appears in the list below.
Escape dots with a backslash (example\.com). An unescaped . matches any character, so example.com would also match exampleXcom.

​
Managing Filters

All filters are listed under the Create a filter form. Use the tabs above the list to switch between:
  • Current workspace — Filters that apply to the workspace you are in
  • All workspaces — Filters that apply to every workspace
Use All, Active and Inactive on the right to show every filter, only enabled filters or only disabled filters.
Deleting a filter cannot be undone. If you might need the filter again, disable it instead.

​
Example: Cleaning Up Emails

Email results from scanned files often include placeholder addresses, library authors and error-tracking addresses. This filter hides the most common ones:
With this filter enabled, addresses like these are hidden from Reconnaissance → Emails: Addresses that belong to your target stay visible.

​
Starter Patterns

Copy these into a new filter and adjust them for your targets.

Tips

  • Start narrow — Filter exact domains first, then broaden the pattern once you have checked what it hides.
  • Test before saving — Try your pattern in a regex tester against a few real values from your results.
  • Use All workspaces for global noise — Placeholder domains and CDNs are the same on every target, so one filter can cover all your workspaces.
  • Use This workspace for target-specific noise — Keep filters for one program’s own test accounts or staging domains in that program’s workspace.
  • Check with the filter off — Before reporting that something is missing, disable your filters to make sure you are seeing everything.
