FAQ

What is penetration testing?

Penetration testing is a security assessment where a professional simulates attack techniques to find weaknesses in an organization’s systems before malicious actors do.

What is the difference between manual and automated pentesting?

The site describes manual pentesting as expert-led testing that can uncover complex or subtle issues, while automated scanning is used for faster checks of known vulnerabilities.

What should I get pentested?

The homepage says the service covers web applications, network targets, cloud systems, mobile applications, wireless networks, and IoT devices, so the right scope depends on what systems store, process, or transmit sensitive data.

How is pentest pricing determined?

The pricing section says the company uses transparent hourly billing and quotes to the nearest hour, with the final cost depending on scope, duration, complexity, and the type of testing required.
