FAQ

FAQ

Does penetration testing affect my service?

Testing is generally conducted in a way that does not affect service availability. High-risk tests (such as DoS) are scheduled after prior consultation or conducted in a test environment.

What is the difference between a vulnerability assessment and penetration testing?

A vulnerability assessment checks for known vulnerabilities based on a checklist. Penetration testing attempts creative attacks like a real hacker to uncover business logic vulnerabilities, chained attacks, and more.

How will I receive the assessment results?

We provide a detailed report (vulnerability descriptions, reproduction steps, risk ratings, and remediation measures). An executive summary report and an in-person briefing are also available if needed.

How does re-assessment work?

After vulnerabilities are remediated, a re-assessment confirms whether they have actually been resolved. Deep Dive and higher services include unlimited re-assessments within 3 months after remediation is completed.

Could information about discovered vulnerabilities be leaked?

Absolutely not. All projects are conducted under an NDA, reports and supporting materials are delivered encrypted, and they are securely destroyed after the project ends.
