Frequently Asked Questions

The first step is a comprehensive audit of your existing APIs to understand what you have, who is using it, and where the inconsistencies and risks lie. This is followed by defining a clear business-aligned strategy that outlines the goals of your API program. From there, we establish a lightweight, cross-functional team to create initial standards for design, security, and documentation.

We follow a defense-in-depth approach. This includes: 1) Strong authentication and authorization using standards like OAuth 2.0. 2) Implementing an API Gateway to enforce policies like rate limiting and input validation. 3) Automating security testing (SAST/DAST) in the CI/CD pipeline. 4) Comprehensive logging and monitoring for threat detection. 5) Adherence to OWASP API Security Top 10 best practices.

Absolutely. We have extensive experience with leading API gateways like Apigee (Google Cloud), Azure API Management, AWS API Gateway, Kong, and MuleSoft. We conduct a thorough analysis of your technical requirements, existing infrastructure, scalability needs, and budget to recommend and implement the solution that best fits your enterprise ecosystem.

We establish a clear and consistent versioning strategy (typically URI or header-based) from the outset. Our governance framework includes a formal process for managing breaking changes, which involves clear communication, deprecation policies, and providing backward compatibility for a defined period to allow consumers to migrate smoothly. The goal is to enable evolution without disrupting existing integrations.

API Governance refers to the people, processes, and standards that define how APIs are designed, built, secured, and published. It's the rulebook. API Management refers to the tools and platforms (like an API gateway and developer portal) that help you execute and enforce that governance across the entire API lifecycle, handling aspects like security, traffic, monitoring, and analytics.
