150+ Enterprise SaaS targets assessed

SaaS application security
protecting your customers' data

SaaS platforms store customer data across hundreds of tenants. A single authorization flaw can expose every customer's data. Enterprise buyers increasingly require security assessments before procurement.

How a Enterprise SaaS engagement runs

SaaS testing concentrates on the seams between tenants and roles. We build accounts at every permission level and walk each one across the other's data — the cross-tenant IDOR that leaks a competitor's workspace is the classic finding here, followed closely by admin endpoints that trust a role flag the client controls. Webhooks, SSO, and API tokens get the same treatment because enterprise integrations multiply the attack surface.

Because procurement teams increasingly ask for evidence, the deliverable doubles as sales collateral: a clean report with verified findings and remediation status shortens security questionnaires and unblocks enterprise deals.

Regulatory and compliance context

SaaS compliance pressure arrives through buyers rather than regulators: SOC 2 Type II reports, ISO 27001 certification, and GDPR data-processing addenda are table stakes for enterprise deals, and every procurement review asks when you last tested. A cross-tenant data leak is both a breach-notification event under GDPR and a contract-termination trigger for most enterprise agreements. Our reports are structured to answer the questionnaire question directly — what was tested, what was found, what was fixed — so the assessment doubles as procurement evidence.

What we typically find in Enterprise SaaS

The signature SaaS finding is cross-tenant IDOR: an object ID guessed or incremented reaches another customer's workspace, invoice, or export. Close behind: role checks enforced in the UI but not the API, so a 'viewer' token calls admin mutations; webhook secrets shared across tenants; and file-export endpoints that stream another tenant's data during a slow scroll of IDs. SSO/SAML misconfigurations — missing signature validation, over-permissive attribute mapping — appear in roughly a third of enterprise-facing apps we test.

What the report includes

Every verified finding with a reproducible proof-of-concept: the exact request sequence, the role it ran under, and the data or action it reached.

Severity rated on impact in your sector — funds moved, records exposed, tenants crossed — not a generic CVSS guess.

Remediation guidance per finding, written for the team that will implement the fix, plus a re-test window to verify each patch.

An executive summary your leadership and security questionnaire reviewers can read without a security background.

Enterprise SaaS assessment FAQ

Can you test without disrupting our customers?

Yes. Testing uses dedicated test tenants and accounts; nothing touches real customer data or shared production workflows without an agreed window.

Will the report satisfy enterprise security reviews?

That is the intent — findings are reproducible, severity-rated, and mapped to common questionnaire themes so they answer procurement reviewers directly.
