Frequently Asked Questions

What’s the difference between offensive and defensive security tools?

Offensive security tools are designed to attack systems, networks, and applications in a simulated manner in order to test their vulnerabilities before an attacker can exploit them.

Defensive security tools are designed to detect, prevent, and respond to attacks.

Are offensive security tools legal to use?

Yes, offensive security tools are legal to use in a controlled environment. However, using these tools for malicious purposes is illegal and unethical.

Therefore, make sure you have proper authorization before using offensive security tools in your organization.

How often should organizations run offensive security tests?

The answer to this question varies depending on your organization's size and level of risk. However, testing every six months or quarterly is common. Testing every day is becoming a best practice, especially when using automated tools like Mindgard.

Regardless of how frequently you test your systems, you should always test immediately after a major update or change in your infrastructure.
