Centralizes API and AI control planes and has enabled federated self-service for many teams
The whole area of API and AI management is quite complex, with so many different ways of being able to do things. I think a positive of Kong is that it's so configurable and extendable, but that is also a con because there are so many ways of achieving the same thing that I think often people are either confused or struggle to get going as to how to solve a particular problem. In my mind, a more opinionated deployment of Kong itself or even how to solve certain use cases would be something I would like to see, so a more opinionated use of their products and configuration of their products on how to solve the most common use cases. That's probably the main thing about needed improvements for Kong Konnect. It's a pretty fully-fledged platform; there obviously are portions of it that could be improved. But I think overall as a platform, it's really good, and I think it can help the majority of organizations looking to manage their throughput of APIs or AI traffic. The majority of what I've said before probably covers the improvements needed for Kong Konnect. There probably are some API Ops and AI Ops changes that could be improved, which is not necessarily the Kong Konnect product, but some of the toolchains around it. I'm thinking around, especially if it's API Ops, about topics like better GitOps processes and the ways of being able to roll back changes when there are issues. At the moment, a lot of that is either non-existent or is hand-cranked. I would like to see the ability to roll back configurations when there are issues being added to the product.

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

"Kong Konnect has positively impacted our organization by securing our APIs, which is one of the main concerns for us, and securing our APIs has benefited our organization by improving compliance and reducing incidents."
"Technical support from Proofpoint was absolutely excellent."
"Their tech support is excellent; when I raise an incident or a support ticket, it gets answered in four hours."
"Since using Kong Konnect, I have observed less time in onboarding external partners for our internal APIs, less time in exposing our APIs with proper authentication and rate limiting, and more collaboration for discovering API specifications across platforms."
"Kong Konnect has impacted my organization positively, particularly in enhancing security and providing a compliance dashboard for applications, making it a very positive impact on my organization."
"Kong Konnect has positively impacted my organization by making our development easier and helping us push new routes to our current customers."
"I think it's a really great tool, and I've seen a number of enterprise companies using it."
"The documentation is excellent, and it includes a developer portal, which helps create a common distribution channel for APIs within and outside the enterprise."
"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."
"OpenLegacy opens the door to connect modern web products to our old legacy system."
"The speed of development of production, especially in specific environments like IBM mainframes, has been valuable."
"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."
"Without OpenLegacy, it would take us several months to create the same services."
"It is possible to solve larger legacy API issues on an enterprise level with this product."
"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."
"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."
 

Cons

"Kong Konnect's RBAC needs to evolve more, as they currently offer only one or two levels of RBAC in terms of organization and teams."
"I think a positive of Kong is that it's so configurable and extendable, but that is also a con because there are so many ways of achieving the same thing that I think often people are either confused or struggle to get going as to how to solve a particular problem."
"I wish Kong Konnect could improve by having a built-in notification system whenever any APIs get pinged so that we can receive alerts and send them to the developer."
"Pricing was the issue as it becomes very expensive due to the nature of local circumstances."
"I do not rate Kong Konnect a nine out of ten because the configuration can be complex and not beginner-friendly."
"Kong Konnect needs improvement in the UI."
"I would recommend that Kong add the capability to sort the routes by name, date, or size, as the current setup does not support this."
"Kong Konnect can be improved by simplifying pricing to make it more transparent, simplifying the user experience so that non-technical people can also configure API specifications, and by supporting more enterprise plugins and third-party integrations to make it more robust."
"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."
"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."
"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."
"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."
