What does an application and API security assessment cover?
An application and API security assessment tests authentication, authorization, input handling, business logic, and sensitive data exposure. For SaaS platforms, MAV also examines tenant separation, roles, account lifecycle, and the ways integrations extend the attack surface.
What we examine
- Object-level and function-level authorization, broken access control, and tenant isolation.
- Authentication flows, session handling, account recovery, and role escalation.
- Injection, file handling, unsafe output, and server-side request forgery.
- Business logic abuse, rate limits, and security assumptions across API integrations.
When this is the right move
SaaS teams, API providers, and product organizations releasing new functionality, onboarding enterprise customers, or reviewing a complex platform.
Turn exploitable application behavior into a focused engineering backlog, with clear evidence your team can reproduce and fix.
