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

"It is a stable solution."
"First of all, the integration with the rest of Microsoft's products is a major win."
"The aspects I find most valuable are the managing the data and applications. I can also restrict the users to install any applications. I can also wipe the data if the phone was missplaced or stolen. These are the basics for me."
"Previously, SCCM was used as an on-premise solution for clients, but now they are moving to Microsoft Intune as a cloud solution with better security and functions."
"I like that we can implement conditional access."
"It is a helpful tool to manage BYOD policies."
"The synchronization of Intune with other Microsoft solutions is a valuable feature."
"One of the main features of the solution is it allows the management of many devices in different ways."
"ISL Online is easy to use and it provides a single platform for various challenges we face in IT."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"ISL is a fundamental partner for us since, throughout all these years, it has allowed us to grow and solve the problems of our customers and their users in a very fast and agile way without having to move, even providing service abroad."
"The most valuable feature is safety."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Without ISL Online, I would not be able to work from home."
"Our computers are spread amongst six physical locations, and TeamViewer reduces the need to travel to those offices to help staff."
"Once you use it, you will never want to use another remote service product again."
"We also use it a lot for remote site assistance. We've set up our internal authentication for unattended access to our remote sites. That makes it very easy and convenient to remotely connect with our users and our client machines whenever we need to. It's set as a direct, secure connection. As long as the station has internet access, we can see it and it makes remote support very simple."
"The most valuable features of TeamViewer are the ease of connecting to remote computers. I do not need a lot of information about their computers to connect, a nontechnical person can give me the information needed for me to connect. Additionally, the solution does not gather other system information about the host or client's systems as other solutions might, such as AnyDesk."
"It is very beneficial if you are unable to access a device physically."
"TeamViewer is a step ahead of solutions like, for example, AnyDesk."
"It is fairly feature-rich and stable."
"Ever since we have been using TeamViewer Business, because of how quick it is to connect to a user across the globe, we have been able to close tickets rapidly."
 

Cons

"One thing I would suggest is that servers are not getting managed through Microsoft Intune."
"Intune has no remote control function for mobile phones to solve issues remotely for users."
"The support is not very good. It's very poor."
"Each feature has a separate license, making logistics and cost management difficult if not strategically bundled together."
"Software or patch management solutions must be complemented with something beyond Microsoft Intune because it doesn't upgrade or manage a list of integrated packages and lacks the capacity to upgrade all kinds of software on computers."
"For additional functionality, I suggest that Microsoft could expand on asset management. Since the platform is there, they could develop it into a full-fledged asset management system."
"From an end-user perspective of Microsoft Intune, I haven't experienced any challenges since installation. However, some customers have reported experiencing slowness when using lower versions of the Android system."
"In the past, I raised some tickets for the enhancement feature, which was missing in Intune."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"I would like to have a little bit more information when new features are released. They have added features that I didn't know about in the past. It would be easier for me to implement new features and consolidate them with other systems in our network if I knew beforehand."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"They need to better advertise the features."
"I would like to be able to access and manage all brands of smartphones."
"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."
"Wish it would support multiple support persons at the same time to assist a client for situations that need team collaboration."
"The product can sometimes crash."
"I would like to see TeamViewer support multiple platforms."
"Support for mobile devices from Linux has been missing since the Native client was rolled out. This was a nice option, especially when trying to walk somebody who was struggling to understand something on their phone."
"The connection and reconnection sometimes lag and can cause problems."
"One thing that would really help with TeamViewer Business is if they were able to provide an easier way to deploy TeamViewer Business on all devices using group policy, as the current solution is quite clunky and very technical to set up; I have struggled and spent many days trying to get TeamViewer Business pushed out via group policy, and it has never worked as we would prefer, so we end up doing it manually, which is a drain on resources."
"It needs to have proper authentication. I would like to see in-depth integration with Google and Microsoft products, for example. It would be nice to have a cell phone version as well."
"Customer support for TeamViewer is quite slow. They do reply, but the reply timing is more than forty-eight hours, which is not acceptable for any service industry."
 

Pricing and Cost Advice

"Its pricing seems reasonable."
"Intune's pricing is reasonable considering its benefits and the high costs it helps avoid."
"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"The pricing for Microsoft Intune is reasonable. Our clients are satisfied."
"Microsoft Intune is expensive."
"While Microsoft charges for actual usage, it lacks discount options."
"Based on the features that it gives, it is cost-efficient. It is not necessarily on the expensive side of the scale. It provides a hefty number of features that any organization would want. It is in a good price range."
"Cost is not my department, but the product is included in the E5 license that we already pay for every user, so no additional cost is incurred."
"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."
"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)."
"It does what I need it to do but I think it's expensive. It wasn't easy for me to get approval from the company to get it... It's costing us about $700 a year, per license."
"We're using the free version. We do not pay any licensing fees."
"I used the free version of TeamViewer."
"There is a free and paid version of this solution. I am currently using the free version."
"The price of the license could be less expensive."
"We have an annual subscription that is just under $1,900 with no additional costs. We get these promotions about upgrades and stuff like that, but we haven't had a need to add more seats. Users can also use TeamViewer for home use with a non-commercial free license."
"The cost of the licenses depends on how you buy them. They just had a buy one get one free deal going, and they do that every once in a while. Where you buy one license, and they will give you the second one free, or you can try to get discounts. Most of our licenses that we have we tried to do something like that just to save some money."
