SaaS Security Review
SaaS penetration testing focused on multi-tenant isolation, RBAC, account takeover, and billing abuse. Purpose-built security testing for startups and growing SaaS companies.
Overview
SaaS products fail in specific ways: one tenant reaching another's data, a viewer escalating to admin, a trial user unlocking paid features, or a webhook that can be spoofed. These are business-critical risks that generic testing often overlooks.
A SaaS security review is tailored to your product's tenancy model, roles, and billing logic. The goal is simple: prove that a paying customer, a malicious tenant, or a low-privileged user cannot cross a boundary they shouldn't.
What you walk away with
- Confidence that tenants are truly isolated from one another
- A clear map of what each role can and cannot do
- Findings framed around real business and revenue impact
- Report suitable for sharing with prospects and customers
What gets tested
A representative view of the attack surface I probe by hand during this engagement.
Tenant Isolation
Cross-tenant data access, shared resource leakage, and object ownership enforcement.
Role-Based Access Control
Every role and permission tested for horizontal and vertical escalation.
Account Takeover
Invitation flaws, password reset abuse, session handling, and SSO edge cases.
Billing & Plan Abuse
Bypassing plan limits, unlocking paid features, and manipulating usage or quotas.
Integrations & Webhooks
Webhook spoofing, OAuth scopes, and third-party integration trust boundaries.
Onboarding & Invites
Team invitation flows, domain claiming, and default permission misconfigurations.
SaaS Security Review — common questions
Testing before launch is ideal. Fixing tenant isolation or access-control flaws is far cheaper before you have customer data and paying tenants relying on those boundaries.
Yes. Enterprise buyers increasingly require evidence of independent penetration testing. You receive a professional report and, on request, a shareable summary letter you can provide to prospects during security reviews.
Billing abuse is a core part of a SaaS review — bypassing plan limits, unlocking paid tiers, and manipulating usage counters are all in scope.
