API & Web Offensive Security
Application-layer testing that catches authentication flaws, business-logic abuse, and API patterns scanners miss.
Offensive testing for web applications and REST/GraphQL APIs.
Why teams engage us
Modern breaches often come through APIs and subtle authorization bugs, not splashy SQLi headlines. GraphQL and microservice sprawl multiply endpoints; OAuth and JWT implementations fail in repeatable ways. Compliance needs more than a DAST screenshot.
What we deliver
We perform manual testing of web applications and APIs (REST, GraphQL, and hybrid patterns) with emphasis on authentication, authorization, session management, input handling, and business-logic abuse. Testing aligns with OWASP guidance and your threat model. Deliverables include reproduction steps, severity, and concrete fix patterns.
How we run it
- Scope: roles, environments, test accounts, and rate limits
- Mapping: endpoints, flows, and trust boundaries
- Adversarial testing: authz, abuse cases, and integration flaws
- Reporting: dev-friendly writeups and verification steps
- Optional retest after fixes
Outcomes you can expect
- Risk-ranked issues with exploit scenarios and affected assets
- Secure development guidance your engineers can apply immediately
- Regression test ideas for CI/CD where applicable
- Executive summary of application risk posture

FAQ
DAST vs manual testing?
DAST scales; manual testing finds logic and authz flaws. We combine tools where helpful but rely on expert analysis for conclusions.
Can you test production?
Often staging is preferred. Production testing requires strict guardrails, data handling agreements, and change windows.
GraphQL-specific issues?
Yes: introspection exposure, resolver authorization, batching abuse, and denial-of-service patterns are common review areas.
