Significant email security benefits combined with efficient spam filtering, yet cost hinders long-term use

The integration with our on-prem Exchange was very straightforward; the only thing we did was redirect all email traffic over Proofpoint, so Proofpoint did everything independently, and we were very happy. I am still receiving emails from Proofpoint's site. Not using it at the moment, but in the short term we will be tackling that portion of the product as well. We cannot provide feedback regarding Dynamics because we are not experienced enough at the moment; we have initiatives going on but did not get enough feedback from end users. Based on my overall experience with Proofpoint, considering the cost perspective, I would rate it a 7 out of 10.

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 documentation is excellent, and it includes a developer portal, which helps create a common distribution channel for APIs within and outside the enterprise."

"Technical support from Proofpoint was absolutely excellent."

"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."

"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."

"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."

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

"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."

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

"It is possible to solve larger legacy API issues on an enterprise level with this product."

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."

"Pricing was the issue as it becomes very expensive due to the nature of local circumstances."

"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."

"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."

"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."
