Centralized device management has automated onboarding and improves remote security compliance
One thing I feel Microsoft Intune could improve is troubleshooting visibility. In many cases, when a policy or application deployment fails, the error messages are a bit generic. So, admins still spend time checking logs manually or testing on devices one by one. Compared to the simplicity of deployment, troubleshooting sometimes feels less mature. I also think reporting and real-time monitoring could be stronger. The dashboard gives useful information, but in large environments, many teams still depend on additional tools or scripts for deeper reporting and analytics. If I had to focus on one area first, I would probably choose troubleshooting and reporting. Deployment through Microsoft Intune is generally straightforward, but when something fails, identifying the exact root cause can still take more time than expected. Error messages are sometimes too generic, and admins often have to dig through logs, sync status, or multiple portals to understand what actually happened. I think user experience and policy management could also improve further. Microsoft Intune has become much better over the years, but sometimes the admin portal still feels fragmented because certain configurations open in different sections or redirect to older interfaces. For new admins, especially, it can take time to understand where everything is located. Another thing is policy conflict handling. In larger organizations, multiple device policies, compliance rules, and configuration profiles can overlap. When conflicts happen, the visibility is not always very clear, so admins spend time figuring out which policy actually won or caused the issue.

Easy to deploy, stable, scalable and safe
I previously used TeamViewer. ISL Online is definitely the better choice compared to TeamViewer, as it offers a more secure connection that does not involve peer-to-peer transport, and all data is encrypted. A single license for ISL Online costs about the same as TeamViewer but with multiple licenses, ISL Online is cheaper.

Remote access has cut critical issue resolution time and supports faster production troubleshooting
Perhaps on the UI side of TeamViewer because we are connecting to different remote desktop connections or remote server connections. Whenever we are working on one of the production issues and we open multiple connections, it is very hectic or confusing to jump from one server to another server. Perhaps on the UI side, if they can improve something related to the view sessions or which session is connected to which remote server, that would be helpful. Perhaps something related to the authentication because it should have a proper authentication mechanism. Every developer should not access TeamViewer or the remote desktop by using TeamViewer. We always have a proper authentication or multifactor authentication mechanism in place, so only those on on-call support or P1 support at that time can access the remote server, but not anyone else. I chose nine out of 10 because sometimes we face the session timeout issue. Suppose during the production support, we connect to one of the remote servers, and if it is idle for approximately 10 or 15 minutes, the session timeout happens. We have to follow the same authentication mechanism to connect to the remote server again. During the session timeout, it delays our process or the troubleshooting steps, which is the reason I have given nine out of 10 instead of 10.

Quotes from Members

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

Pros

"I have seen a return on investment right from the start of the tool's usage."
"Microsoft Intune has transformed my organization; we are managing to scale the Intune deployment across all our regions efficiently, and it works perfectly for our needs."
"The most valuable feature of Microsoft Intune is patching-related capabilities."
"The solution appears to be stable and scalable."
"The best thing about Intune for the customers is simply that it's included in the different plans of Microsoft 365."
"The interface is user-friendly, and the reporting tool works in real-time."
"We saw a strong return on investment with Microsoft Intune, as it reduced the time spent on device provisioning, software deployment, and security policy management through automation and centralized control while also enabling faster onboarding for new devices, improved compliance management, and lower operational overhead for the IT team by reducing the need for manual device configuration and support."
"Intune simplifies compliance. The ability to manage software updates and policies on endpoints has helped us meet contract requirements."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"ISL Online is easy to use and it provides a single platform for various challenges we face in IT."
"We can also monitor our systems at any time from practically anywhere."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Setting up the solution is easy and there's no maintenance involved."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"The most valuable feature is safety."
"We are just much more responsive, we can be faster, and we can support our customers in a better way because when they have a problem, we can be on their computer immediately."
"The most valuable feature of TeamViewer Tensor is the remote access."
"The TeamViewer system has some built-in security. The TeamViewer client connects to the TeamViewer host securely. Only a certain number of authorized users on our side have access to the system. Even within that, an individual endpoint can be assigned to a group, where not everybody has access but, rather, just one or two people who are part of a support team might have access to that particular device. So TeamViewer has given us tools to be able to segregate who has access to different things."
"The usability and graphic interface stand out for me because it is very easy to understand, with upper bars, all the features, and the file transfer functionality."
"I find the mouse control and the ability to click for them very effective. I can move the mouse and click on buttons as if sitting at their computer. These are the basic features I use most often in the solution. There are tricker features that I don't use much because I don't need them frequently. Overall, it's a great tool for helping others with their computer issues without traveling to their location or another building."
"It's very easy to set up."
"The pilot feature is what stands out the most. I love the ability to use the pilot feature for remote inspections. The augmented portion of the software comes in handy when I have to assist my inspectors. They use the app in the field, and they show me what they're seeing through their phones."
"It is very beneficial if you are unable to access a device physically."
"It's worth every penny; I would recommend it any time."
 

Cons

"It would be better if Microsoft can reduce the cost of the license, as we know the Intune device subscription is licensed per device at a cost of $2 a month, but for the best enhanced security and features we must add an add-on license or buy or upgrade to a bundling license such as M365E5."
"Microsoft Intune has a latency response time issue. The latency has room for improvement."
"Automations in Microsoft Intune can be more elaborated; KQL (Kusto Query Language) is available, but if multiple automation options were readily available, which would include PowerShell, KQL, JSON, and different interpreters like VS Code or Python readily available from Microsoft Intune, it would help administration and management much better."
"I would say the interface and dashboard summarizing the devices' status and compliance could be improved."
"I wish Microsoft would keep up with their documentation. They make changes so quickly to these platforms that they do not update the documentation properly in a timely manner."
"If we can not seem to get even half a dozen users working with the product in a way we consider stable, the scalability is in question."
"I find the solution quite old school with not many features."
"Areas for improvement in Intune include expanding support beyond Samsung devices to accommodate other Android manufacturers like Redmi and Motorola."
"There could be a section in the menu describing the new features and changes."
"What bothered me the most was that when I connected to the computer at the office, I was afraid that someone would turn on the monitor and watch what I was doing."
"We miss the possibility to communicate via head-set in ISL. At the moment, we combine ISL for visual communication with Skype for verbal communication."
"It would be helpful if they had iSupport for supporting Apple phones."
"If there is an update or new feature on ISL Online, I don't know about it. I would be happy to receive a newsletter or notification of new features or updates."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"I would like to be able to access and manage all brands of smartphones."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"TeamViewer Business's scalability is bad because it's very expensive."
"Full integration of computer's user account system. Be able to login using the local computer's credentials rather than setting up a unique Teamviewer account/password."
"Oftentimes, the session window blocks view of the system tray. I’d like to be able to minimize it or move it."
"TeamViewer could be more secure."
"In the past, use in wireless environments caused buffering due to limited bandwidth."
"I would like to see something like a TeamViewer mobile application for iOS or possibly Android. I think this would be fantastic given how technology is evolving today. It would be beneficial to use it with your smartphone."
"On occasion, when remote connection process can't connect to a machine, the error messages aren't always helpful to tell you why you can't connect, as the message doesn't help troubleshoot whether it is too slow, too much interference, etc. I usually have to run to another computer and figure out what is going on, then restart it. The diagnostics could be improved."
"I would like to see TeamViewer support multiple platforms."
 

Pricing and Cost Advice

"On a scale of one to ten with one being the cheapest, the cost of Microsoft Intune is a five."
"Existing E5 license holders for M365, Intune, and Azure, receive a free license."
"The product is offered as part of a Microsoft standard bundle. The pricing can be competitive to Airwatch, and Maas360."
"The cost is somewhat on the higher side, particularly when considering certain price points, especially in markets like India."
"There is a license needed for this solution and it is either included in one of the enterprise license agreements. Microsoft licensing is a mathematical institute, it could be quite complex. We tend to ask specialized organizations to research what the most profitable way it would be for us to use licenses in the organizations."
"There is a license needed to use the solution and we are on an annual license."
"If you ask the accountant or the finance department, they'll tell you that it is way too expensive, but when I look at the cost and compare it with the value you actually get, it's more than fair."
"It's reasonable. They're not giving it away, but it's reasonable."
"We have a pay-per-use license available for 500 minutes within one year for 95 Euros. However, this option is not popular. Alternatively, we can purchase a one-year license for 339 Euros; if we need two licenses, the cost is double, and for three licenses, the cost is triple with a ten percent discount. For 99 Euros a year, we can open multiple sessions on the same computer with a multi-session subscription."
"TeamViewer was willing to give us a one-year package. Whereas, a lot of the other companies that we explored were paid by the month or quarter. It's just easier for our finance people at the college if we can make a one-time yearly payment."
"It would be nice if it is cheaper."
"We have a corporate license. The maximum amount number of users changes based on the amount you pay. E.g., with our license, there is a maximum amount of users who can use the solution at the same time (10 users)."
"There is a free and paid version of this solution. I am currently using the free version."
"The price was cheaper than what we were previously paying. At the time that we went with TeamViewer, we were using ShareConnect. The TeamViewer package was about half the cost and able to have a bigger number of users."
"TeamViewer has multiple licensing options."
"It has probably saved us several thousands of dollars because we have quick access anywhere. We don't have to worry about finding people onsite or arranging conference calls. We also save time and money with it because we don't have to send somebody onsite to troubleshoot."
"I rate pricing a ten on a scale from one to ten, where one is low and ten is high. There are no additional costs attached to the licensing of the solution."
