API Security Implementation
Building authentication, authorisation, input validation, rate limiting and monitoring into your APIs, protecting the data and functions they expose to apps and partners.
Overview
Why it matters
for your business.
APIs expose business logic and data directly, which makes them attractive to attackers. Common failures include endpoints returning other users’ records when an ID is changed, excessive data in responses and no limits on automated abuse. We implement controls that address the OWASP API Security Top 10 in your services and gateway.
Work covers OAuth 2.0 and JWT handling with proper validation, object-level authorisation checks, schema-based input validation, response filtering, rate limiting and quotas, secure partner credentials and API inventory to find forgotten endpoints. Security events are logged for monitoring. Where you use an API gateway, we configure policies there while keeping critical checks in the service code.
What's included
- API inventory and risk assessment
- OAuth 2.0 and JWT validation implementation
- Object-level authorisation checks
- Schema validation and response filtering
- Rate limiting and partner key management
- API security event logging
Outcomes
What changes
for your business.
Ideal for
- Fintech platforms with partner APIs
- Mobile app backends
- Businesses joining open data ecosystems
Data exposure reduced
Authorisation and response filtering limit what each caller can read, reducing leakage of other users’ data.
Abuse kept in check
Rate limits and quotas make credential stuffing, scraping and automated misuse harder.
No forgotten endpoints
An up-to-date API inventory helps you retire or protect old versions attackers might target.

FAQ
Common
questions.
Something else on your mind? Ask us directly.
Is an API gateway enough to secure our APIs?
A gateway helps with authentication, rate limiting and traffic control, but it usually cannot enforce business-level rules such as whether a user may access a specific record. Those checks must also live in your service code. We implement both layers.
How is this different from API testing?
API testing verifies endpoints behave correctly and finds defects. API security implementation builds and configures the protective controls themselves: authentication, authorisation, validation, rate limits and logging. Security testing afterwards then checks those controls work.
