Pentests for multi-tenant SaaS,the way your auditor will read them.
Multi-tenant isolation, webhook signing, SCIM provisioning, admin APIs, the surfaces your auditor flags and your customer-procurement teams test in their security review. Our engagements stage isolation drift, signing bypass, and admin-API IDOR as reproducible PoCs. Reports accepted by SOC 2 Type II, ISO 27001, GDPR, and customer-procurement teams.

Tenant boundaries, by hand
Cross-tenant IDOR across record IDs, slugs, integration tokens, search APIs, and billing meters.
Working proof-of-exploit
Captured SAML wrap, SCIM role-escalation transcripts, webhook replay traces. Not a checklist score.
Re-test included
Every finding re-tested after fixes ship. Written closure for SOC 2 + ISO 27001 evidence.
Three ways we test multi-tenant SaaS.
Tenant isolation, webhook signing, SCIM, admin APIs, customer-facing copilots. Pick the engagement that fits where your product is right now.
BugDazz Autonomous
Runs between SOC 2 cycles against tenant boundaries, OAuth scopes, SCIM flows, webhook HMAC and timestamp checks, and admin APIs. Re-tests every push.
Red team engagement
Adversary emulation against your production admin APIs and customer-tenant boundaries, with no warning to the on-call rotation. Output reads like an incident write-up.
AI and LLM pentest
Tests customer copilots and internal agents for prompt injection, cross-tenant data exfil via retrieval, function-call abuse, and system-prompt extraction.

On record
Why a SOC 2 audit isn't a pentest
A control marked effective is not a tenant boundary held.
SOC 2 Type II tells your auditor that the control runs. It does not tell anyone whether a paying tenant can read another tenant's data through an admin-API parameter that nobody on your team has touched in six months. SecureLayer7's pentesters chain the surfaces the audit grades green: a webhook signature that fails open on a missing header, a SCIM provisioning race that grants workspace-admin to a deactivated user, an audit-log endpoint that accepts an injected event with the wrong tenant ID. Then we walk the proof your auditor will accept and your team will fix.
Scope —
Every SaaS attack surface. Not just the OWASP top ten.
Six surfaces we exercise on every tech SaaS engagement. Multi-tenant isolation and identity sit at the top; data-export and supply-chain close the loop.
Multi-tenant isolation
Cross-tenant IDOR across record IDs, slug prediction, integration-token replay, search-API boundary leaks, billing-meter tampering.
OAuth, SSO, SCIM provisioning
SAML signature wrap, OAuth scope drift, SCIM admin-role escalation, JIT-provisioning race across Okta, Azure AD, Google Workspace, Jumpcloud.
Admin API and internal tools
Retool-class admin exposure, super-admin scope creep, internal-API allowlist drift, support-impersonation paths to production data.
Webhook signing and replay
Webhook-secret leakage, signature wrap, replay-window abuse, integration-partner trust boundary, event-source spoofing.
Audit log and SOC 2 evidence
Log tampering, retention bypass, audit-event injection, after-the-fact rewrite, tenant-scoped log exfil.
Data export, rate-limit, supply chain
Bulk-export drift, GDPR subject-access boundary, per-tenant rate-limit bypass, free-tier escape, dependency confusion, secrets-in-history.
IN SCOPE.
Where we look across a tech SaaS stack.
Record-level, workspace-level, organization-level boundaries probed across IDs, slugs, search APIs, and integration tokens.
Scope drift, signature wrap, role-escalation, JIT race across every supported IDP.
Signing bypass, replay-window abuse, super-admin scope, internal-tool exposure.
Log integrity, retention, audit-event injection, subject-access boundary, bulk-export drift.
TECH SAAS ATTACK SURFACE.
What an attacker chains to cross tenant boundaries in a modern SaaS stack.
- 01Cross-tenant IDOR
Record-ID, slug, or integration-token leak across workspaces, exfiltrating another tenant's customer data through the same product API.
- 02SAML signature wrap to admin takeover
IDP response re-wrapped to swap the subject, granting workspace-admin or org-owner in a single sign-on flow.
- 03SCIM role-escalation to workspace admin
SCIM patch on a deactivated user races provisioning, lands an attacker role inside the target tenant before deprovisioning settles.
- 04Webhook signing bypass to state poisoning
Missing signature header treated as valid, replay-window left open, injected events flip billing, role, or integration state.
- 05Audit-log tampering to SOC 2 evidence gap
Log retention bypass or audit-event injection rewrites the trail, breaking the evidence chain your auditor needs for CC controls.
- 06Admin-API exposure to super-admin access
Internal-tool allowlist drift or support-impersonation endpoint reachable from outside, granting cross-tenant read or write.
- 07Dependency confusion to build-pipeline RCE
Namespace squat or registry-priority flip lands attacker code inside CI, with secrets and signing keys reachable from the build runner.
MULTI-TENANT CHAIN CLASSES.
TECH SAAS METHODOLOGY.
Eight phases. Tenant-aware, evidence-ready.

- 03Admin-API surface enumeration
- 04Webhook signing and replay probe
- 05Audit-log integrity and retention review
