SaaS VAPT

Protect the SaaS platform behind your customers' data. NuageSEC's SaaS VAPT assesses the application's attack surface and relevant supporting components to identify, validate and prioritize security weaknesses within the authorized scope — with tenant isolation as a central concern for multi-tenant platforms.

Protect the SaaS Platform Behind Your Customers' Data

A SaaS platform can combine customer-facing applications, APIs, authentication systems, multiple user roles, administrative functions, integrations and cloud infrastructure.

For multi-tenant platforms, one security boundary becomes especially important: can one customer access another customer's data, functionality or resources?

NuageSEC's SaaS VAPT assesses the application's attack surface and relevant supporting components to identify, validate and prioritize security weaknesses within the authorized scope. NuageSEC's published SaaS security guidance specifically addresses applications, APIs, authentication, authorization, user roles, tenant isolation, business logic, integrations and relevant cloud infrastructure.

What Does SaaS VAPT Assess?

01
Tenant IsolationValidate separation between customer organizations.
02
Authentication & AuthorizationAssess identities, roles and access boundaries.
03
Web ApplicationsCustomer, partner, support and administrative portals.
04
APIsPublic, authenticated and internal APIs supporting SaaS functionality.
05
Business LogicSubscriptions, approvals, payments, exports and other critical workflows.
06
Administrative AccessPrivileged and support functionality.
07
Cloud InfrastructureRelevant cloud resources where explicitly included.
08
Third-Party IntegrationsExternal services and trust boundaries.

Why Is Tenant Isolation Critical?

Multi-tenant applications serve multiple customers through shared application environments and often shared infrastructure or databases. OWASP identifies cross-tenant data leakage, tenant impersonation, broken tenant isolation, IDOR and cross-tenant privilege escalation as key risks.

The assessment checks whether application and API authorization controls correctly prevent unauthorized cross-tenant access.

01
Tenant A UserAn authenticated user belonging to one customer organization.
02
Application / APIThe shared application or API layer serving all tenants.
03
Tenant B ResourceA resource belonging to a different customer organization.

SaaS VAPT validates whether this path is actually blocked by authorization controls, not just assumed to be.

SaaS VAPT vs Web Application VAPT

Web Application VAPT focuses on the security of the application. SaaS VAPT adds platform-level security questions, particularly:

This distinction is reflected in NuageSEC's current SaaS penetration-testing scope guidance.
