FAQ
Will you fix the vulnerabilities you find?
Every package includes detailed remediation guidance. The Premium package also includes hands-on fix implementation support.
Is my source code kept confidential?
Yes. Your code is handled with strict confidentiality and is never shared, reused, or stored beyond the review. An NDA can be signed upon request.
How should I share my source code?
You can provide a read-only Git repository, a ZIP archive, or another secure method that we agree on before the review begins.
Do you use only automated tools?
No. I combine manual secure code review with SAST tools to identify vulnerabilities that automated scanners often miss, reducing false positives and improving accuracy.
