Why Vaultline
Why Work With Vaultline
01. Attacker-grade, not checklist-grade.
We go past the OWASP scan into trust boundaries, logic abuse, and the assumptions your code was built on. That's where real losses live and where checkbox audits never look.
02. One team, full kill chain.
The engagement can extend from code review to live pentest, phishing simulation, and red team. Same attackers, deeper access, no re-scoping between vendors.
03. Reports built for your auditors too.
Findings structured to support ISO 27001, SOC 2, and CERT-In requirements: executive summary for leadership, reproduction steps for engineers, retest and clearance letter included.

Methodology
[ Testing
Approach ]
Five stages from threat model to clearance letter. Every serious finding proven with a runnable PoC and traced to its root cause.
Scope & threat model
System boundary, adversary, trust zones.
Architecture review
Where the bug classes will live, before line-level review.
Hybrid testing
Manual review + automated analysis + dynamic testing, across app code, cloud config, and CI.
Exploitation & root cause
Runnable PoCs for serious findings, traced to the design assumption that produced them.
Report, retest, clearance
Live walkthrough, patch re-testing, clearance letter.
Compliance
Standards We Test Against
Reports structured to support ISO 27001, SOC 2, and CERT-In requirements.
