Thorough Recon for Pentesters

The application of Spyse will greatly speed up the recon process by saving time on the installation of tools, studying syntax, and waiting for scanning processes to complete. Other than the subdomain finder, Spyse collects a great deal of data from all over the web, ranging from network connections and detailed technical information to the vulnerabilities of each separate element in the given network. Here you will find all you need for qualitative penetration testing.


Advanced Search

The Advanced Search tool lets you extract precise data using search filters. Obtaining the required information usually takes a while because most often you have to go through a bunch of superfluous data before getting the results you need.

Advanced Search allows using up to 5 search filters to find much more precise data, for example: find all subdomains with specific content in the meta, with exact vulnerability type, and technology related to some organization or country.

Feel free to use Advanced Search with our Subdomain Finder as well as when looking for other types of data. The search options are limitless.


Spyse Scoring

The scoring system was developed to quickly scale through the security status of various network elements like IP, domains, entire infrastructures, and organizations.

This service compares all information gathered by our scanners with CVE databases and provides a security assessment score with the ability to inspect the details of each vulnerability.
