Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

Centralized AI control has standardized our workflows and delivers faster, more reliable features
There are definitely some places where Portkey can be improved. Overall, the experience has been positive, but the first area is analytics and reporting. While the observability feature is excellent, we would like to have richer historical analytics and customizable dashboards. For example, it would be useful to see trends by applications and teams or features over long periods without exporting data to an external BI tool. Another area is governance for large organizations. As AI adoption grows, enterprises need more granular, role-based access control. We would like to see more advanced AI evaluation capability built into the platform itself, including features such as prompt versioning and automated quality scoring and regression testing. Finally, while the platform is supported with multiple providers, we would welcome even more intelligent routing capabilities, such as automatically selecting the best model based on latency, cost, and task complexity using configurable policies. These are not major pain points, but they are enhancements that would make an already strong platform even more valuable for an organization that scales their AI workloads. Documentation and onboarding could be enhanced. Portkey is developer-friendly, but we need more end-to-end references, architecture, and implementation guides for common AI patterns. This would help teams adopt it even faster. I did not give Portkey a perfect score because while it has become a foundational component in our AI stack and solves several operational challenges, I would still like to see deeper analytics, stronger enterprise governance features, and more built-in AI evaluation capabilities, especially for prompt testing, regression analysis, and model benchmarking. I would be comfortable recommending Portkey to any organization that is building multiple AI applications or wants to manage a scalable way to handle LLM providers and produce AI traffic.

Quotes from Members

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

Pros

"With the Vprobes, we quickly identified issues on the application servers, which we normally couldn't, where it usually would be a full circle round between our NOC and server people."
"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
"Stability-wise, I rate the solution a ten out of ten."
"The ability to be able to do detailed traffic analysis such as top-talkers, application-specific monitoring, and understanding them through patterns, is helpful. We're also able to gain an understanding of voice calls, voice traffic, whether we have packet loss in a certain part of the network or jitter or high latency that might be impacting the network. All of those are nice functionalities."
"An issue that used to take days is now fixed within minutes to an hour."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"The solution gives us increased visibility while conducting an IT deployment, recording data all the time so we have the before picture and the after picture, and in areas where we have instrumentation, we have seen a measurable decrease in mean time to know and mean time to repair."
"Whenever there is an outage, it's quickly able to identify it and, without pointing fingers, we can prove that it is not the network environment."
"Portkey is totally stable; it is one of the best software solutions in the market for this purpose."
"Portkey's visualization is excellent, I particularly appreciate the multiple capabilities they have introduced, especially the MCP gateway, which is outstanding, the caching mechanism is very good, and the logs and traceability features are also excellent."
"Overall, Portkey has had a huge business impact in terms of cost savings and operational efficiency."
"Portkey definitely provides a solid alternative solution for the agent and large model hosting platforms, and it is very helpful for us to explore the possibilities across the industry rather than staying with a few mainstream options."
"Portkey has significantly improved the organization by streamlining the AI processes being followed."
 

Cons

"There are so many features that it makes it hard to know it all. You end up paying for things that you don't use and probably don't even need. It might be better if Netscout came up with a modular way to pay for what you're going to use and not pay for all of this "white elephant" without being able to take advantage of all of it."
"Our biggest area of concern right now, supporting the applications, is that while NETSCOUT does a good job of monitoring the network and the applications, we need more visibility into system health and performance monitoring."
"There are so many pieces of their product that integrate with one another that perhaps a recommendation for improvement would be some sort of bigger overview and map to help understand how all their pieces integrate together."
"There's a little too much investigation that the user has to do at this point."
"Initial setup was complex."
"I would like to see improvement in the user experience. It's hard to manage it. We need a dedicated, highly-qualified person, compared to similar tools. Obviously, it's in a higher bracket, salary-wise. That's something the NETSCOUT team needs to focus on. It's a completely niche-skill technology, where we need to have the skills to manage, maintain, and deploy it."
"A lot of tools highlight what's going on but they don't actually pinpoint the user experience. It would be good if there were a small message or something highlighting what the user experience is like and any degradation that's actually occurring."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"The main area for improvement is onboarding and trial experience."
"End-to-end traceability is not fully fulfilled. They are only fulfilling about 50 to 60 percent of our end-to-end agent traceability requirements, and the remaining functionality needs to be implemented."
"However, one thing I would like to say is that it could have better documentation."
"One major problem I see with Portkey is that when I had not yet started any trial, it started to denote that I had exceeded the prompt limit."
"There are definitely some places where Portkey can be improved."
 

Pricing and Cost Advice

"If you are able and you are willing to use everything that Netscout provides to you, it's probably a relatively fair price. The problem is that it's such a large and such a complex tool that I'm not sure that many companies would be able to use it entirely, the way it's expected to be used."
"I would like it to be more scalable with less spend."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"There is a need to make yearly payments towards the licensing charges attached to the product. The product may come across as a cheap tool for some, while it may seem costly for others."
"The platform is expensive."
"I rate the price of NETSCOUT nGeniusONE a four out of five."
"It can be expensive, but if you have a good configuration, based on what you are looking for, it's okay, it's manageable."
