Microservices Architecture
— SaaS & Technology
Microservices Architecture engineered for the SaaS & Technology threat landscape. Every finding is backed by proof-of-concept evidence.
Free Scoping CallSaaS & Technology Vulnerability Intelligence
SaaS platforms serve as critical infrastructure for thousands of businesses. A single tenant isolation failure can cascade into a multi-organization data breach affecting millions of end users.
Multi-Tenant Data Isolation Failures
Insufficient tenant boundary enforcement in shared infrastructure allowing cross-tenant data access, configuration leakage, and privilege escalation between customer environments.
OAuth/OIDC Implementation Flaws
Misconfigured OAuth flows enabling token theft, redirect URI manipulation, scope escalation, and authorization code interception in SSO integrations.
GraphQL Query Depth and Batching Exploits
Unrestricted GraphQL query complexity allowing denial-of-service through deeply nested queries, field suggestion enumeration, and batch query abuse for data exfiltration.
CI/CD Pipeline Poisoning
Compromised build pipelines enabling supply-chain attacks through malicious dependency injection, pipeline variable manipulation, and artifact tampering.

Frequently Asked Questions
What methodologies do you use?
We base our testing on OWASP Testing Guide, PTES, NIST SP 800-115, and OSSTMM frameworks.
Can we get references from previous clients?
Due to NDA constraints we cannot share client names, but we can provide sector-specific references and case studies.
Do you test remotely or on-site?
Most tests are conducted remotely via VPN. For internal network and physical security tests, we deploy on-site teams.
