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 solution's technical support is good and fast in terms of responsiveness and problem-solving skills."
"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."
"I like everything about it. It provides the security we need."
"Protocol transformation is the most valuable feature of Kong Enterprise."
"The clients that we have already deployed are happy with it."
"This is a solid intrusion prevention system that combines a firewall and antivirus in a single solution."
"Kong Gateway Enterprise is quite comprehensive."
"It offers a wide range of plugins that we leverage, including OIDC, Rate Limiting, Lambda functions, and more."
"Opens the door to connect modern web products to an old legacy system."
"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."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
"The product has helped our business by allowing us to become more efficient in data handling."
"OpenLegacy provides a way to go from the outside world to the legacy mainframe, to move the old standard application to a REST API application. New digital services can be created in a few clicks and this can be done easily by COBOL programmers."
"Without OpenLegacy, it would take us several months to create the same services."
"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."
 

Cons

"The product's price is an area of concern where improvements are required."
"Kong Enterprise fails to provide live tracing of the APIs, which is possible nowadays."
"Kong Enterprise needs to improve its pricing, which starts at hundreds of thousands of dollars. Pricing should be based on API usage rather than monthly. It should improve its documentation as well."
"From an improvement perspective, the product should offer more readily available connectors and also allow for more seamless AI integrations."
"We would like to see an automatic data API when we have a table in the database."
"We are facing issues with the solution's features like reports and traffic analysis."
"There should be an easier way to integrate with other solutions, even though it's the same API solution layer."
"Because it is open-source, it should be less expensive than others."
"Debugging and logging for programmers could be better."
"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."
"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."
"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."
"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."
"We would also be more than happy if the product had the option to work in the opposite direction – the ability to consume REST/SOW services in the outer world from the mainframe."
"Debugging and logging for programmers could be better."
"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case."
 

Pricing and Cost Advice

"The licensing fees are paid yearly."
"It's expensive in Thailand (10 million baht, in Thai currency)."
"The licensing is expensive."
"I don't have any information on licensing costs currently."
"Kong Enterprise's pricing is reasonable for our company size."
"The price is really reasonable compared to that of alternative solutions."
"There are many factors that influence the price of Kong Enterprise, such as scale, licenses, and usage."
"Basically, my company uses the tool's open-source version."
"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."
