Frequently Asked Questions

How is the Runtime Application Security Testing schedule determined?

After a preliminary analysis where we map all targets, we calculate the man-day effort and present a finalized schedule.

Do you help remediate the vulnerabilities?

Absolutely. Our report includes specific remediation advice tailored to your tech stack and infrastructure.

Are reports legal compliance documents?

No. Our reports are not certifications or legal compliance documents; they are technical evidence packages prepared with recognized methodologies such as OWASP and NIST.
