Modernization projects have progressed well but documentation and security guidance still need work

Bringing in additional features to Kong Gateway Enterprise would not necessarily help it. Improving the existing features, increasing security, and adding robustness would be more beneficial. The focus should be on stabilizing the product, improving it, and increasing the documentation. Kong should focus on how the product can be self-onboarded or self-implemented, as this would ease and help customers significantly. The necessary deployment of Kong Gateway Enterprise, API management, and guidance on how customers can use it or improve that area would be helpful. Security is a major concern, especially with new security architecture coming into place. These are the areas that should be prioritized. Beyond these areas, I do not see anything lacking. Kong Gateway Enterprise is quite comprehensive.

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 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."

"It offers a wide range of plugins that we leverage, including OIDC, Rate Limiting, Lambda functions, and more."

"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."

"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."

"I like everything about it. It provides the security we need."

"This is a solid intrusion prevention system that combines a firewall and antivirus in a single solution."

"In our buying companies' perspective, it was easier to use compared to other platforms. The markets were pretty familiar with the solutions."

"The tool's scalability is good...The solution's technical support is good."

More Kong Gateway Enterprise pros

"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."

"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."

"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."

"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."

"Without OpenLegacy, it would take us several months to create the same services."

"Opens the door to connect modern web products to an 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."

More OpenLegacy pros

Cons

"The tool needs improvement in UX."

"From an improvement perspective, the product should offer more readily available connectors and also allow for more seamless AI integrations."

"There should be an easier way to integrate with other solutions, even though it's the same API solution layer. Comparability will be a good improvement."

"Kong Enterprise can improve the customization to be able to do the integration properly."

"Kong is meant for north-south communications, so it will be interesting to see what solutions they can come up with in the realms of east-west communications, service-to-service communications, and Zero Trust architecture. I believe that if they can provide for these areas, then they will be able to solve the overall integration and security concerns for microservices architecture in general."

"The tool needs to improve in areas like documentation and UI."

"We would like to see an automatic data API when we have a table in the database."

"The main challenge, in my opinion, is the price. It's difficult to convince our management to approve the budget to purchase it from our vendor. There are no technical problems."

More Kong Gateway Enterprise cons

"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."

"Debugging and logging for programmers could be better."

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing."

"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."

"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."

More OpenLegacy cons

Pricing and Cost Advice

"Basically, my company uses the tool's open-source version."

"I don't have any information on licensing costs currently."

"There are many factors that influence the price of Kong Enterprise, such as scale, licenses, and usage."

"There is a need to pay towards the licensing charges...In some areas, the functionalities are available free of charge."

"Kong Enterprise's pricing is reasonable for our company size."

"Kong Enterprise is cheaper than Apigee. I rate its pricing as four out of ten."

"The licensing is expensive."

"The product is reasonably priced because it goes by the SaaS model."
