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.

Reliable remote access has improved secure collaboration and streamlined daily approvals
The best features TeamViewer Business offers in my opinion are collaboration, templates, a high level of security, and session recording. Collaboration allows me to collaborate remotely with my team members. Besides reconnecting automatically, it provides a high level of security, protecting from cyber attacks and aids in providing assurance in regulated environments through two-factor authentication and end-to-end encryption features. It also allows recording live sessions, which can be replayed as needed for future reference. TeamViewer Business has positively impacted my organization as collaboration has enhanced, especially remote collaboration by 60 to 70 percent. I have been able to collaborate with clients and other team members seamlessly. Enhanced workflow efficiency includes faster approvals and a lowered risk of data loss, misuse, and leak through robust features like two-factor authentication and end-to-end encryption. It also facilitates compliance using documentation and auditing through recordings and logs.

Quotes from Members

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

Pros

"Its direct integration with all the other products that we have from Microsoft is valuable. We're using the E5 license, and we have a whole wealth of different products available. It just makes it easier to have everything from one provider."
"For the price, the features included with Microsoft are appealing."
"Intune is a very good product and everything is cloud-based, and it provides a very simple unified platform to manage everything from the single management console."
"Microsoft Intune brings all our endpoint and security management tools into one place, acting as a comprehensive solution where we can manage numerous devices and configuration profiles, and block specific URLs, among many other capabilities."
"I find Microsoft Intune valuable primarily for its Windows management capabilities, along with its Android Enterprise and Apple device management for mobile devices."
"Microsoft Intune solutions, especially Microsoft Intune and Microsoft 365, have positively impacted my organization by improving endpoint security, enabling centralized device management, supporting remote work efficiently, reducing manual administrative effort through automation, and enhancing compliance and collaboration across the enterprise environment."
"Microsoft's licensing is more flexible and adaptive than its competitors."
"Microsoft Endpoint Manager's patch management has been the most helpful to us."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Good communication is a key to good business and ISL helps a lot."
"Without ISL Online, I would not be able to work from home."
"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 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."
"ISL Online is easy to use. It provides a single platform on which we can do everything, and it's very low maintenance. After installation, you don't need an IT manager or staff to watch over it. It's secure. It's most important for us."
"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."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"The solution has worked flawlessly; it’s stable and reliable, with no bugs or glitches."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"The solution is scalable."
"TeamViewer is a scalable solution."
"We use TeamViewer for our help desk to manage and troubleshoot remotely."
"It was worth the investment. You can do file transfers and video calls with it. You can do a lot of copy paste stuff. E.g., if I have a file and want to place it on somebody's machine, I can just copy it off of mine and paste it right on their machine. I don't have to put it in a Dropbox account and have them log into it to pull it off. I can do all that right through TeamViewer. When you're looking at the TeamViewer screen, you think you are working on your own machine."
"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, and the solution does not gather other system information about the host or client's systems as other solutions might, such as AnyDesk."
"It is easy to use and has a pretty good UI."
 

Cons

"I think there should be a better tracking of the cell phones used on the Intune."
"Those are the two features that did not impress me much, and currently with other customers I am improving them with Microsoft directly."
"Microsoft Intune could be faster with client to server communication. Whenever I push something, it takes time; sometimes it takes more than one hour to deploy on the Windows side."
"The information we receive at the device level needs improvement."
"The most significant challenge is reporting and monitoring. The reporting accuracy for deploying applications and all aspects of Intune needs to be improved."
"More integration with monitoring tools is needed."
"The granular support for other device types in Microsoft Intune could be improved."
"The most significant challenge is reporting and monitoring. The reporting accuracy for deploying applications and all aspects of Intune needs to be improved."
"We miss the possibility to communicate via head-set in ISL."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"There could be a section in the menu describing the new features and changes."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"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."
"The only thing I wish for is a better price for small users."
"The security could improve in TeamViewer."
"Quick User Switching has a very nasty tendency to render the screen output unstable."
"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."
"The performance could always be better."
"TeamViewer Business's scalability is bad because it's very expensive."
"If were to I put myself in the seat of a small business owner, I would prefer TeamViewer to be more of a pay-once-and-own-it solution, rather than paying via a subscription model (although I am using the free version). Only annual subscriptions are available. It makes paying for it the first time seem a little daunting."
"They really need an AMT client and/or iLO client for business use."
 

Pricing and Cost Advice

"Intune's pricing is reasonable considering its benefits and the high costs it helps avoid."
"The E5 license is expensive."
"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."
"The price is very reasonable."
"The pricing for Microsoft Intune is reasonable. Our clients are satisfied."
"I liked the tool's pricing until P2 came into effect. I am unsure about the current value versus the cost of the new licensing model."
"Microsoft Intune is not cost-effective as a standalone product."
"My team members bundled it together with their Microsoft solutions, including Microsoft 365 and related products."
"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."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"TeamViewer is $600 or $700 per port per year..."
"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."
"It would be nice if it is cheaper."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"TeamViewer has multiple licensing options."
"I used the free version of TeamViewer."
