Eyeballer: Give those screenshots of yours a quick eyeballing.

Eyeballer is an AI-powered, open source tool designed to help penetration testers assess large-scale external perimeters.

About Eyeballer

Our award-winning tool leverages a convolutional neural network for analyzing pen test screenshots.

Eyeballer is meant for large-scope network penetration tests where you need to find "interesting" targets from a huge set of web-based hosts. Go ahead and use your favorite screenshotting tool like normal (EyeWitness or GoWitness) and then run them through Eyeballer to tell you what's likely to contain vulnerabilities, and what isn't.

With Eyeballer Penetration Testers can:

  • Assess a repository of screenshots for indications of potential vulnerabilities.
  • Supplement automated scanning methods to close gaps in coverage.
  • Gauge targeted external perimeters, big or small.
  • Focus manual review efforts.
  • Improve testing times and accuracy.

Eyeballer was named 2019 “Web Filtering and Control Solution of the Year” by CyberSecurity Breakthrough, a leading independent market intelligence organization that recognizes the top companies, technologies, and products in the global information security market.
