Find authorization and tenant isolation failures before customers do
A focused SaaS security audit for API authorization, tenant isolation, RBAC, IDOR/BOLA, exports, webhooks, billing workflows, and audit evidence.
The boundaries that usually fail in SaaS products
The goal is to prove whether your API and workflow boundaries still hold when the actor, tenant, role, or object context changes.
API authorization
Verify that actor, role, and object mismatches do not return data or allow the wrong action.
Tenant isolation
Check whether tenant-scoped reads, exports, jobs, and shared resources stay in the right boundary.
RBAC and role boundaries
Test whether lower roles can still reach privileged endpoints, actions, or admin paths.
IDOR / BOLA
Replay object identifiers and nested resources to expose object-level access failures.
Cross-tenant data exposure
Compare responses across tenants to catch silent leakage even when the API still returns 200 OK.
Audit logs and evidence quality
Check whether logs can explain who did what, when, and under which tenant or actor context.
Webhooks and exports
Validate trust boundaries around inbound events, report generation, and downloaded data.
Billing and plan enforcement
Verify that plan state, entitlements, and billing workflow checks are enforced server-side.
Buyer-friendly output with technical proof
The audit is written so engineering, leadership, and security reviewers can all understand what failed and what has to change.
Evidence-based findings
Clear proof built from request and response behavior, not static assumptions.
Severity and impact framing
Buyer-friendly severity language tied to actual access or exposure risk.
Request-level reproduction notes
Enough detail for your team to replay the issue during remediation and review.
Remediation guidance
Practical direction for the boundary, query, or control that needs to change.
Retest notes
Clear validation points for confirming the fix closes the same exploit path.
Buyer-friendly summary
A concise readout that supports leadership, procurement, and engineering review.
Send the API surface and main concern.
If you already know the risky flows, jump straight to the request form. If not, the sections below explain what inputs help us scope the review.
A usable audit starts with a few practical inputs.
We do not need a perfect security package. The fastest path is usually a clear product surface, a few test accounts, and the workflows that carry the most business risk.
- API documentation or main flows
- Test accounts with different roles or tenants
- Auth flow overview
- Critical business objects
- Main risk concerns
- Timeline
A focused process with clear checkpoints
The cadence depends on scope, but the work usually moves through these stages.
Initial scope review
We map the main flows, tenant model, and boundaries that are most likely to matter in your SaaS product.
Focused testing
We run controlled request mutations across actors, tenants, roles, and objects to expose authorization failures.
Findings review
We package the results with evidence, impact, and remediation direction so engineering can act quickly.
Retest support
If you fix the issue, we can replay the same path and confirm the boundary now holds.
Send the product surface and we will scope the audit.
Use the form to share the product, the backend stack, and the main concern. We will use that context to shape the audit around the highest-risk boundaries first.
We do not need production credentials or sensitive customer data to start scoping the audit.
Technical focus
We look for request behavior that proves the boundary fails, then package the evidence so your team can replay it.
Buyer-ready output
The findings are written for engineering, leadership, and customer review without exposing raw internals.
