SaaS & B2B Cloud Pentesting & VAPT

SOC 2, ISO 27001 and CREST-aligned PTaaS for multi-tenant SaaS, B2B platforms and developer tools.

Why it matters

Multi-tenancy is the most expensive bug class in SaaS. StartSecure focuses on tenant isolation, RBAC abuse, webhook trust boundaries and supply-chain risk — the exact pattern enterprise buyers and SOC 2 / ISO 27001 auditors care about.

Top threats we find

Attack patterns specific to SaaS & B2B Cloud

Tenant isolation bypass

Cross-tenant IDOR, broken authorization, shared cache poisoning, leaky search indexes.

RBAC & permission flaws

Privilege escalation via API parameter tampering, role-confusion, SSO/SAML scope abuse.

Webhook & integration abuse

Unsigned webhooks, SSRF via outbound integrations, OAuth token leakage.

Supply chain & CI/CD risk

Compromised actions, secrets in build logs, dependency confusion.
