Penetration Testing

You can’t measure the effectiveness of a cybersecurity program on paper; your security controls must be put to the test.

Identify Vulnerabilities Before the Hackers Do

Data breaches continue to dramatically increase in both size and impact. Penetration testing is designed to assess the cybersecurity of your organizational technologies and systems.

Zeroday has certified penetration testers ready to stress test your organizational setup.

Zeroday’s OSEE, OSCE, and OSCP Certified Penetration Testers will use the latest cybersecurity tactics, so you have confidence that your organization’s critical data is protected.

Our experienced team employs automated and manual techniques to find weaknesses in servers, end-user workstations, wireless networks, and web-based applications while also assessing security awareness, and the human-layer and physical facility controls.
