Seamless integration and efficient security boost API management capabilities
More plugins for additional integrations would be helpful and openness for traditional development languages, such as .NET, because many enterprises are looking for .NET solutions or incorporating with .NET solutions. I mostly missed local resellers or partners that we could use within our enterprise, because it was difficult for some tech personnel to work with remote tech support.

The biggest advantage is how simple the technology was.
I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be. OpenLegacy handles the bread-and-butter TP monitoring stuff, but I am working for one of the six banks in the United States still using the Hogan mainframe, which has a slightly proprietary mechanism. But OpenLegacy currently doesn't have a connector for Hogan. So it would help if they could build one. That would appeal to financial institutions that still use Hogan, like US Bank, Wells Fargo, KeyBank, and Vanguard.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The features I like include ease of operation and implementation in a cloud environment, the dashboarding features for API statistics, and the user-friendly developer portal."
"Protocol transformation is the most valuable feature of Kong Enterprise."
"The tool's feature that I find most beneficial is rate limiting. In our usage, especially in the financial sector, we prioritize limiting API usage. This is crucial because we provide APIs to other companies and must ensure they adhere to their allocated usage limits. Without rate limiting, there's a risk of excessive usage, which could result in significant costs."
"The solution provides good performance."
"The tool's scalability is good...The solution's technical support is good."
"In our buying companies' perspective, it was easier and more unique to use compared to other platforms."
"The most valuable feature of Kong Enterprise is its capability to integrate with various security tools."
"There are a few features that I like about Kong when it comes to authentication and authorization. Specifically, being able to use Kong for role-based access control (RBAC), and then further being able to integrate the RBAC mechanism with our enterprise directory, was very useful."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"The product has helped our business by allowing us to become more efficient in data handling."
"The biggest advantage of OpenLegacy was how simple the technology was. We were able to build out the OpenLegacy parts very quickly. We put together a couple hundred APIs in six months."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
"Using OpenLegacy, the exposure of services is far easier and quicker. In many cases, exposure of services requires just a few clicks and takes only minutes. In very complex cases, it still only takes half a day. Without OpenLegacy, it would take us several months to create the same services."
"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."
"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."
 

Cons

"Kong Enterprise can improve the customization to be able to do the integration properly."
"The ease of billing is lost when Kong is not available directly on the Azure marketplace. This is one area where they can improve."
"Kong Enterprise fails to provide live tracing of the APIs, which is possible nowadays."
"The software version upgrade process should be improved."
"The product's price is an area of concern where improvements are required."
"The tool needs to improve in areas like documentation and UI."
"Understanding the configurations and knowing what needs to be done can be a bit difficult initially."
"The technical support team's response time needs to be improved."
"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case. We are currently working with OpenLegacy to cross the SSL bridge and suspect that most users will want to do the same."
"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."

"Debugging and logging for programmers could be better."
