Security features excel but development limitations emerge
We are using the IBM DataPower Gateway for security purposes. As per the development perspective, there are some limitations with IBM DataPower Gateway because it only supports XML and XSLT language, but it does not support the Java language. This is the only limitation of the IBM DataPower Gateway. For the authentication and authorization purpose, we can use the IBM DataPower Gateway. It's a very good product. We are mostly using the IBM DataPower Gateway for security purposes and load balancing purposes. If we are handling the load for a particular server, then we can use the IBM DataPower Gateway. The IBM DataPower Gateway is mostly used for security purposes. If we have some APIs and we are using some security for those APIs, then we can use it. It can also be used as a load balancer. It's also used for certificate management, user management purposes, authentication, and authorization. For routing, the IBM DataPower Gateway has multiple URL-based routing and content-based routing capabilities. If we have multiple URLs, then we can use an XML script. Using the XSLT language, we can configure multiple URLs and implement URL-based routing. Content-based routing means if we have multiple requests, we can route the request to a particular URL. For this, we need to use the XSLT language only. We can't use XML, Java, or other scripting languages. With IBM DataPower Gateway, we are using all the APIs. All APIs have been configured on the gateway. We have configured the particular TLS profile and some TLS client profiles as well. Using that TLS profile, we have configured the APIs and authentication. We have configured some tokens also, including JWT tokens and different types of auth tokens. There is also a rate limiting feature which we use for handling API loads.

Collaborative API workflows have improved testing speed and streamlined multi-team releases
The best features of Postman Enterprise are team collaborations, automated API testing, environment management, and API governance. The shared workspace and collections make collaborations very smooth across the teams, and automated testing and CI/CD integrations help catch issues early. I also appreciate the governance and security features because they help maintain API standards and consistency across large projects. API governance has helped my team maintain consistent API naming, request structures, and documentation standards across multiple services, reducing confusion between the teams and making onboarding easier. On the security side, environment variables and access control helped me avoid exposing sensitive data such as tokens or API keys, and they also made collaborations safer because different teams could access only the resources they needed. I found that the collections runner and automated testing features are very valuable because they save a lot of manual task time and help identify issues quickly during deployments. Postman Enterprise has improved collaborations, reduced API integration issues, and sped up the testing cycles in my organization. It provides a centralized platform for API development, documentation, and testing, which has improved consistency while reducing communication gaps between the frontend, backend, and QA teams. It has also helped catch issues earlier in the development cycle, improving overall release quality.
