Penetration Testing
Enterprise buyers run security questionnaires. Procurement teams ask for pentest reports. Your SaaS security posture is now a sales asset — or a deal-breaker. We help you make it the former.
About This Service
Security assessment specifically designed for SaaS platforms — testing multi-tenancy isolation, business logic, SaaS-specific OWASP risks, and the data boundaries that keep your customers’ data separate and secure.
SaaS applications carry a unique risk: a vulnerability that affects one customer’s data can affect every customer. Multi-tenancy flaws, subscription bypass, and business logic errors are routinely under-tested — until an enterprise customer’s security review or a real incident forces the issue.
OWASP Top 10, OWASP API Security Top 10, SOC 2 requirements
Typical Timeline: 5–10 days depending on platform complexity
Report: Executive summary + full technical findings
Retest: Complimentary, included in every engagement
NDA: Signed before any technical discussion
Deliverables
SaaS security risk overview for product, engineering, and leadership teams
Detailed documentation of all cross-tenant access vulnerabilities found and their impact
All findings with OWASP classification, proof-of-concept, and CVSS scores
Dedicated section covering all REST endpoint vulnerabilities with endpoint references
Fix guidance written for your backend and frontend development teams
Findings mapped to relevant compliance controls to support your compliance programme

Scope
Tenant isolation and data segregation — can one tenant access another’s data?
Business logic flaws specific to subscription and billing systems
Role-based access control — admin, user, and API-level authorisation
SaaS-specific OWASP risks — account takeover, mass assignment, excessive data exposure
Customer data handling and PII exposure in API responses
Integration security — OAuth flows, webhook security, third-party app integrations
Onboarding and invite flow vulnerabilities
Admin panel and super-admin access control
Session management across multi-tenant contexts
Exported data and report generation security
Process
Every engagement follows a defined, transparent process — no surprises, no hidden scope changes, and no invoice for work you did not agree to.
Map all tenant roles, subscription tiers, API endpoints, and integration points.
Attempt cross-tenant data access from multiple test accounts.
Test subscription flows, permission models, and feature access controls.
Test all REST endpoints, webhooks, and OAuth integrations.
Risk-rated findings with SaaS-specific context and remediation guidance.
Verify that critical isolation and access control issues have been resolved.
Why Us
Automated tools find known signatures. Our certified consultants find the chained attack paths, logic flaws, and context-specific vulnerabilities that no scanner will surface. Every finding we report is manually verified — zero false positives.
Every finding includes a proof-of-concept, a CVSS risk score, the affected system or endpoint, and step-by-step remediation guidance written for the team that has to fix it. Your developers and your board both get a report they can use.
We sign a formal NDA before any technical discussion begins. Your vulnerabilities, your architecture, and your engagement findings are treated with the same confidentiality as attorney-client communications. We have never disclosed client information.
Every engagement includes a complimentary retest once your team has addressed the findings. We verify that the vulnerabilities are genuinely closed — not surface-patched — and issue a formal retest certificate you can share with clients and auditors.
We don’t apply a generic web app methodology to SaaS platforms. We test the specific risks that matter for multi-tenant products — tenant isolation, subscription enforcement, admin privilege models, and data boundaries — with test accounts across all user tiers your platform supports.

FAQ
SaaS testing places particular focus on multi-tenancy — ensuring data belonging to one customer cannot be accessed by another. It also tests SaaS-specific business logic such as subscription enforcement, feature gating, and admin privilege models that general web application testing may not adequately cover.
Yes. We test both B2C and B2B SaaS platforms and can simulate multiple account types — end-user, team admin, organisation admin, and super-admin.
Yes. We recommend testing against a staging environment with production-equivalent data and configuration to minimise risk to live customers.
SaaS companies frequently need to demonstrate security posture for SOC 2, ISO 27001, and increasingly for enterprise customer procurement. Our findings map to these frameworks.
