Featured Reviews

Sathyan K - PeerSpot reviewer
Banks achieve seamless data transformation and integration with enhanced security and scalability
From the automation perspective, IBM B2B Integrator has its own powerful workflow, but compared to other applications such as MuleSoft or Boomi, they have many cloud connectors and multiple connectors for integrating with Salesforce or other CRM or ERP applications, whereas here you may have to develop them, which is not native. There is room for improvement in IBM B2B Integrator, particularly in the automation parts, and from a UI perspective. They are making some changes to make it more intuitive. The current UI is not aesthetically pleasing, but features-wise, it is rich enough to provide all the valuable information required.

Maharsh-Kapadia - PeerSpot reviewer
Transforms enterprise integration with comprehensive platform and excellent support
The best features of this solution are that everything we get into a single platform, whether it's integration, API, or data modeling; everything is available in one platform. It's a hybrid, including cloud and on-premise solutions with good connectivity and good connectors. From the benefits of using Mule ESB, we could reduce the manual tasks to 50% in one to two years. The cost is still something we are trying to make lower because we see some advantages when we move from point-to-point integration to API-led connectivity. We have seen a lot of reusable assets, so the cost is reduced. Ultimately, we want to see how it's transformed into business revenue; that's what we are still looking into.
