Solution / API Security
Secure the interfaces connecting your digital systems.
VaptStack assesses APIs for weaknesses across authentication, authorization, data exposure, business logic, and system integrations.
API security
Every API is part of the attack surface.
APIs connect applications, users, services, and data. A weakness in authentication, authorization, input handling, or business logic can expose systems beyond the API itself.
VaptStack examines APIs in context, considering how endpoints behave individually and how they interact as part of a larger application architecture.
Assessment areas
What we examine
Authentication
Assess how APIs identify clients and users, including tokens, sessions, credentials, and authentication flows.
Authorization
Test whether API users can access resources or perform actions outside their intended permissions.
Data Exposure
Examine API responses and request handling for unnecessary, sensitive, or improperly protected data.
API Logic & Integration
Analyze workflows, endpoint relationships, and integrations for weaknesses that can create exploitable attack paths.
What we look for
Security across the API lifecycle.
Access
Can users reach what they should not?
Examine object access, role boundaries, and authorization logic across API resources.
Data
Is the API exposing too much?
Review request and response behavior to identify unnecessary or sensitive data exposure.
Logic
Can workflows be abused?
Test how endpoint combinations and application workflows can behave under unexpected conditions.
Testing process
Map first. Test deeply.
Understanding the API architecture provides context for finding meaningful weaknesses.
