Keep every customer inside their boundary.
We challenge object ownership, tenant controls and hidden role assumptions across the full API.
API penetration testing
Test the assumptions
behind every endpoint.
We test REST, GraphQL and mobile backends as a real attacker would: across roles, tenants, objects and business-critical workflows.

Protect the business behind the API
Stop one broken permission from becoming a customer breach.
We test the relationships automated scanners cannot understand, then translate every weakness into business impact your team can act on.
Protect the workflows that move money and data.
Abuse testing covers states, sequences and race conditions, not only malformed requests.
Ship APIs buyers can trust.
Clear evidence and verified fixes support enterprise reviews, partners and internal security decisions.
Attack surface
More than endpoint scanning.
API risk lives in relationships: who owns an object, which state transitions are valid and what happens when calls are chained.
Authorization
Object, function and property-level controls across users, roles and organizations.
Authentication
Tokens, sessions, recovery flows, MFA boundaries and account lifecycle weaknesses.
Business workflows
State manipulation, race conditions, pricing abuse and unintended action sequences.
Data exposure
Excessive responses, hidden fields, enumeration and sensitive data crossing tenant boundaries.
How we test
Model the API. Break the trust model.
Map
We inventory endpoints, roles, identifiers and the data relationships behind them.
Model
We reconstruct expected permissions and business-state transitions.
Attack
We test cross-user, cross-role and cross-tenant abuse, then chain promising weaknesses.
Verify
Every reported issue includes concrete impact, evidence and a retest after remediation.
Output
Findings your API team can reproduce.
Each issue connects the affected request to the broken security assumption and the business impact.

Request-level reproduction steps
Authorization matrix gaps
Attack-chain evidence
Risk-based prioritization
