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

"Its price is reasonable. It is a part of our M365 suite."
"Mobile device management is most valuable."
"The core management feature in Intune is invaluable to us, especially considering the challenges we often face with System Center when pushing external updates."
"What I like most about Intune is its seamless enrollment process, particularly the Autopilot method."
"The user experience of Microsoft Intune is very friendly and the interface is very good."
"The automatic patch management feature in the Intune Suite is helpful."
"Configuration profiles, remediation, scripts, and auto-pilot features are very good."
"I appreciate Intune's autopilot feature, which allows us to enroll devices and install applications to meet corporate requirements seamlessly."
"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."
"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 most valuable feature is safety."
"Setting up the solution is easy and there's no maintenance involved."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"The stability is great; reliability is what's very important to me, as well as security, and this solution may have only had one instance of downtime in 14 years."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"There is a relevant return on investment, especially when my previous organizations assisted with remote access features, as rather than needing to go on-site, we could connect remotely, making it easier for those who are not tech-savvy, thanks to TeamViewer Business's user-friendly features, which helped immensely, especially when assisting elderly clients, and ensured we met metrics effectively, creating a significant positive impact."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"This solution is straightforward to use."
"The product allows easy access to any system in case of any issues."
"There are only two of us in the core of the company and we manage about 500 machines based in the UK, mainland Europe, US, Hong Kong, China and South Africa."
"TeamViewer is very easy to set up, use, and instruct others to get running, which is great for support."
"It is quite simple to set up."
"I like that it helped a lot, even with low bandwidth network connectivity. For example, while I was traveling, sometimes there were requirements for me to join a TeamViewer session and provide technical support. I was able to do that without much of an issue. It is also a secure solution."
 

Cons

"The main disadvantage seen today is regarding Linux clients. We have a lot of development resources that have Linux on their clients, and we can't manage them on the same platform, as we do with other clients such as macOS and Windows. So, it should have support for Linux clients. It should also have better support for macOS."
"There are challenges with Intune, specifically in reporting. Many third-party companies offer single-pane-of-glass reporting that shows you what your update environment looks like, how your patch is doing, application status, etc., but Intune's reporting is not intuitive. You can connect to Azure, monitoring, and the workbooks, but it's not streamlined."
"I expect Microsoft Intune to have more features in the cloud because there are two major functionalities that we need to be added. This is software metering and license management. These functionalities, for now, must be on-premise. For this purpose, we have set up a SQL Server and I hope that in near future this option will be in the cloud in Microsoft Intune."
"In the past, I raised some tickets for the enhancement feature, which was missing in Intune."
"We've faced significant pushback with Copilot as our clients aren't seeing a favorable cost-benefit analysis."
"What frustrates me the most is just waiting and tapping my fingers, uncertain about whether my changes will take effect."
"Microsoft Intune has potential for improvement; I would like to see a lot more customization in the reporting tools."
"More integration with monitoring tools is needed."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"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."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"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."
"There could be a section in the menu describing the new features and changes."
"We’ve never really contacted technical support. I can’t really speak to how helpful they are as I don’t have much experience with them."
"TeamViewer is expensive, and you get a limited number of connections for your money."
"We would like to have an option to create subgroups, where only members of the subgroup have access to the other members."
"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."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"It's pretty limited on the options they have."
"It would be beneficial to have group functionalities to separate access when many consultants want to access different departments or clients at the same time."
"TeamViewer Business can improve in terms of price and the complexity of licensing, which is a drawback, especially for smaller teams or casual users due to frequent license changes and forced upgrades."
 

Pricing and Cost Advice

"For Microsoft 365 E5 clients, cost is not an issue as this product is one of the benefits."
"I would rate the price a four out of ten with ten being the most expensive."
"No one can compete with Microsoft when it comes to price, and the features it is offering."
"Microsoft Intune is included in the E5 license at no additional cost."
"We spend a lot of money on Intune licensing, and some of our users have to be double licensed just because of how our dev and corporate environments are segmented."
"Any bundle package, such as Security E3, covers multiple things, such as AAP, BitLocker, etc. If you go for them individually, they would be more expensive. Bundling makes the price more attractive and competitive."
"Intune is included in the Microsoft 365 licensing package that we have."
"In terms of the product price and licensing costs, my company finds the product to be reasonably priced."
"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 offers a free version to try. Download and give it a shot. See what it's like and if you like it, then buy the license for it."
"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."
"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 solution's pricing is reasonable."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"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."
"I used the free version of TeamViewer."
