SaaS Penetration Testing
Secure your multi-tenant platform, protect customer data, and build the trust enterprise buyers demand. We test the attack paths that matter most to SaaS companies — tenant isolation, API abuse, privilege escalation, and authentication bypass.
Get StartedSecurity Challenges for SaaS Platforms
SaaS applications face unique risks that generic penetration tests miss. These are the attack surfaces we focus on.
Multi-Tenant Data Isolation
One tenant accessing another tenant's data is a company-ending event. We test shared databases, storage layers, caching, and queue systems for cross-tenant data leakage.
API Abuse Prevention
SaaS platforms live and die by their APIs. We test for broken object-level authorization, mass assignment, rate limiting gaps, and injection attacks across your API surface.
Authentication & SSO Security
Enterprise customers require SAML, OIDC, and SSO. We test your identity layer for misconfigured flows, token handling flaws, session management issues, and MFA bypass.
Privilege Escalation Across Tenants
Role hierarchies in SaaS platforms are complex — admin, member, viewer, billing, across multiple organizations. We test every privilege boundary for horizontal and vertical escalation.
Insecure User Onboarding Flows
Invitation links, self-service signups, trial accounts, and org creation flows are prime targets. We test for account takeover, invitation hijacking, and unintended access during onboarding.
Third-Party Integration Security
Webhooks, OAuth app integrations, marketplace connectors, and embedded widgets expand your attack surface. We test for SSRF, token leakage, and insecure callback handling.
How We Help SaaS Companies
We combine deep application security expertise with an understanding of SaaS architecture to test what matters most.
Web Application Testing
Deep testing of your SaaS application's multi-tenant logic, role-based access controls, business logic, and data handling. We test as multiple tenant users to find cross-tenant vulnerabilities that scanners miss.
API Security Testing
Full-scope assessment of your REST and GraphQL endpoints against the OWASP API Security Top 10. We test authentication, authorization, rate limiting, input validation, and data exposure across your entire API surface.
Cloud Security Assessment
Configuration review of your AWS, Azure, or GCP infrastructure aligned with CIS Benchmarks. We evaluate IAM policies, network segmentation, storage permissions, and secrets management that underpin your SaaS platform.
Mobile App Testing
Security evaluation of your iOS and Android companion apps, including local data storage, certificate pinning, API communication security, and reverse engineering resistance.
Why SaaS Penetration Testing Matters
The failure that ends a SaaS company is not downtime. It is one customer seeing another customer's data. That usually comes from something small: a report endpoint that filters by user but never by organization, a cached response served across tenants, a background job that resolves a record ID before it checks which workspace owns it. Invitation and trial signup flows fail the same way, quietly adding someone to the wrong organization. None of it shows up as an error. It shows up in a support ticket, or in the middle of an enterprise prospect's security review.
We test SaaS platforms the way those flaws are actually found: with real accounts in more than one tenant and more than one role — owner, admin, member, viewer, billing — running the same requests side by side and comparing what each one is allowed to see. A single-account scan cannot find a cross-tenant flaw because it has nothing to cross into. On top of that we test the identity layer your enterprise buyers ask about (SAML and OIDC flows, token handling, session management, MFA bypass), the REST and GraphQL surface against the OWASP API Security Top 10, and the integration edges — webhooks, OAuth apps, and marketplace connectors — for SSRF, token leakage, and insecure callback handling.
You get an experienced tester, a report that works both as SOC 2 evidence and as the document you hand a prospect during a security review, and free retesting within 30 days so remediation is verified before that report leaves your hands. Testing runs against staging or production, whichever fits your risk tolerance, coordinated with your team. We work with organizations across the Charlotte, NC area and nationwide.
Frequently Asked Questions
How much does a SaaS penetration test cost?
A typical SaaS engagement combines the application, its APIs, and the cloud environment behind them. Web application testing starts at $3,500, API testing starts at $3,500, and a cloud security assessment starts at $3,000. Final pricing depends on the number of user roles, endpoints, and cloud accounts in scope. See our full pricing breakdown, or get a free, scoped quote within 24 hours.
How do you test multi-tenant isolation?
We create or receive accounts across multiple tenants and systematically test every API endpoint, data access path, and shared resource for cross-tenant leakage. This includes testing direct object references, database query manipulation, cache poisoning between tenants, and shared storage access. We focus on the real-world attack paths that lead to one customer accessing another’s data.
Will a pentest report help us pass SOC 2 audits?
Yes. A penetration test report is a key artifact for SOC 2 Type II audits, specifically for the CC7 (System Operations) and CC8 (Change Management) criteria. Our report documents testing scope, methodology, findings, and remediation guidance in a format that auditors expect. Many of our SaaS clients use our reports directly in their audit evidence packages.
Can we share the pentest report with enterprise prospects?
Absolutely. Many SaaS companies use our pentest reports to close enterprise deals faster. We deliver a professional, executive-friendly report alongside the detailed technical findings. You can share it directly with prospects during security reviews, or we can provide a summary letter confirming the assessment was completed and findings were remediated.
Do you test in production or staging environments?
We can test in either environment. Production testing gives the most realistic results but requires careful coordination to avoid impacting real users. Staging environments work well when they mirror production architecture and data patterns. We recommend staging for initial assessments and production for validation, but we’ll work with your team to determine the best approach for your situation.
Can you test our CI/CD pipeline and deployment process?
Yes. We can review your CI/CD pipeline configuration for security issues including exposed secrets, insecure build steps, insufficient access controls, and supply chain risks. This is typically scoped as part of a broader cloud security assessment and helps ensure that your deployment process doesn’t introduce vulnerabilities into production.
