Step 1 — Add a target

  1. Go to Targets in the left navigation.
  2. Click + Add target in the top-right corner.
  3. Enter the domain, subdomain, or IP address you want to scan.
  4. Choose the target type:
    • Infrastructure — use for IP addresses, mail servers, and network-level assets. Topscan checks open ports, services, and network-level vulnerabilities.
    • Web Application — use for websites and web apps. Topscan performs web-specific checks: exposed paths, HTTP misconfigurations, outdated web software, and more.
  5. Optionally add tags to organize targets by team, environment, or project.
  6. Save the target.

Tip: Not sure which hosts you own? Use Discovery to automatically find subdomains and related assets from a root domain, then add them as targets in one click.

Step 2 — Run a scan

Once your target is saved, you're ready to scan.

  1. Click New scan — the button is always visible in the top-right corner of the app.
  2. Select the target(s) you want to scan.
  3. Choose the scan type:
    • Fast — covers the most common and critical checks. Completes in minutes.
    • Deep — comprehensive scan across all available checks. Takes longer but finds more.
  4. Click Run scan.

The scan will appear under Scans → In progress. You'll see a progress bar and estimated time remaining.

Step 3 — Review the results

When the scan completes, it moves to Completed scans on the Scans page.
