APIs increasingly connect Canadian organisations' applications, mobile platforms, cloud services, customers, partners and internal systems.
The main security question is not simply whether an API requires authentication. It is whether every request enforces the correct identity, authorisation, object ownership, business rules and data-access controls. NuageSEC provides API security testing for REST, GraphQL, SOAP and gRPC APIs, combining automated analysis with expert manual testing.
Browsers, iOS/Android & Canadian client platforms
Routing, rate limits & authentication layer
Business workflows & tenant-level authorisation
Databases, personal records & cloud repositories
NuageSEC's current API service explicitly covers authentication, authorisation, tenant isolation, object ownership, business logic, rate limiting and API inventory.
OAuth, OIDC, JWTs, API keys and authentication/session handling across all client types.
Object-level and function-level access controls to prevent horizontal and vertical privilege escalation.
Validating whether one authenticated user can access objects or data records belonging to another user or tenant.
Evaluating whether legitimate API workflows can be manipulated to produce unauthorised business outcomes.
Assessing whether APIs return excessive personal or financial information beyond what the caller should receive.
Testing throttling, abuse resistance and resource-consumption controls under sustained stress.
Discovering public, internal, partner and relevant undocumented endpoints within authorised scope.
Reviewing gateway policies, transport encryption, CORS headers, schema enforcement and deployment controls.
NuageSEC currently identifies REST, GraphQL, SOAP and gRPC among its supported API technologies. Each architecture introduces distinct security considerations.
Assess access control, authentication, input handling and data exposure across RESTful endpoints.
Assess authorisation, schema exposure, excessive queries, field-level access and business logic.
Assess enterprise and legacy integrations, XML/message-security controls and envelope validation.
Assess service-to-service authentication, authorisation and cloud-native microservice communication controls.
Canadian SaaS environments frequently combine multi-tenant applications, public APIs, partner integrations, cloud infrastructure, identity services and administrative functions. Testing should establish clear boundaries across all vectors.
Can Tenant A access Tenant B's objects?
Testing whether data filters, tenant IDs, and token claims strictly isolate multi-tenant environments.
Can users invoke functions outside their roles?
Validating whether standard users can access administrative endpoints, billing controls, or export tools.
Are object identifiers correctly authorised?
Verifying that every direct object reference (ID, GUID, hash) is checked against the caller's active session.
Are sensitive fields restricted from callers?
Ensuring responses do not expose internal IDs, hashed passwords, tenant metadata, or excessive personal fields.
Do workflows enforce intended state changes?
Evaluating whether multi-step checkout, verification, onboarding, or approval workflows can be skipped.
Do partner APIs follow appropriate security boundaries?
Testing whether third-party webhooks, integrations, and external client keys are isolated from core systems.
NuageSEC's API testing materials specifically address tenant isolation, role-based access, object-level authorisation and function-level authorisation to safeguard multi-tenant platforms.
Where PIPEDA applies, the Office of the Privacy Commissioner requires safeguards appropriate to the sensitivity of personal information and protection against unauthorised access, use, disclosure, copying, loss or modification.
API security is particularly relevant where APIs transmit or expose personal information, customer records, or financial data. Flaws like BOLA or excessive data return directly compromise personal information safeguards.
The applicable privacy law may differ by organisation and province, including substantially similar private-sector laws in Alberta (PIPA), British Columbia (PIPA), and Quebec (Law 25).
Security testing provides technical evidence about your API implementations; it does not constitute a blanket legal compliance determination.
NuageSEC's published Vancouver e-commerce engagement provides direct Canadian evidence of web-application and digital platform security testing.
The client operated an e-commerce platform handling customer accounts, payment workflows and order management. Testing identified SQL injection, XSS, weak authentication and broken access-control scenarios.
Although the engagement was a web-application assessment rather than a dedicated API case study, it directly demonstrates the type of authentication, authorisation, input-handling and business-impact analysis critical to modern connected digital platforms.
API vulnerability scanning can identify known technical weaknesses automatically. API security testing adds expert manual analysis to evaluate complex logic, multi-step workflows, and authorization.
Identifies known technical weaknesses, outdated libraries, missing TLS configurations, and basic signature-based flaws across endpoints.
Adds expert manual testing to evaluate permissions, object ownership, business workflows, session behaviour, tenant isolation and data access.
NuageSEC explicitly describes API security testing as combining automated analysis with expert manual testing rather than relying solely on vulnerability scanning.
NuageSEC's current API security service states alignment with the OWASP API Security Top 10, OWASP ASVS, OWASP Testing Guide and OpenAPI Specification, alongside other security frameworks.
Framework alignment provides a structured security baseline. It does not replace application-specific testing or understanding the actual business logic of the API.
NuageSEC's API service identifies executive reports, technical details, evidence, remediation guidance and retesting among its deliverables.
A structured catalog of all identified, tested and undocumented endpoints, parameters and methods.
Detailed vulnerability breakdowns, affected endpoints, request schemas and architectural root causes.
Reproduction steps, raw HTTP request/response proofs and parameter manipulations for every finding.
CVSS v3.1 scoring calibrated to your organisation's real operational exposure and business criticality.
Clear contextual translation of what each technical finding means for customer trust, operations and data integrity.
Actionable, code-level recommendations, framework-specific fixes and gateway configuration patches.
A strategic summary written for Canadian leadership, CISOs, board members and enterprise procurement.
Rigorous verification of developer fixes and updated attestation documentation where retesting is included.

Yes. Both are included in NuageSEC's current API testing coverage.
Yes. Object-level authorisation is explicitly covered.
Yes, where internal APIs are within the authorised assessment scope.
It can provide technical evidence and identify data-access and security weaknesses, but it does not itself establish legal compliance.
Yes, where retesting is included.
Identify authorisation gaps, tenant-isolation weaknesses, sensitive-data exposure and business-logic vulnerabilities before attackers exploit them.
