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
Comprehensive 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.
Frequently Asked Questions
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.
