Web Application Penetration Testing
Web Application Security Review
A high-growth SaaS platform engaged CipherTest to validate the security of a new customer portal before a major release. Manual testing uncovered a privilege-escalation chain that would have exposed tenant data.
Engagement Objectives
- Validate multi-tenant isolation before GA launch
- Assess authentication and session handling
- Verify admin-surface access controls
Approach
We began with a scoping workshop to align on in-scope assets, rules of engagement, and success criteria. Over the following weeks, our consultants applied a manual-first methodology aligned to Web Application Penetration Testing, validating every finding before reporting and coordinating closely with the client's engineering team.
Outcome
We identified a cross-tenant access-control flaw and two authentication weaknesses. The engineering team remediated all findings before launch, and our free retest confirmed closure.
