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

"Microsoft Intune brings all endpoint and security management tools into one place, and for app discovery, deployment, and automatic updating, it's reliable."
"The main benefit for us with Microsoft Intune is centralized management of all devices, allowing us to apply one policy across the company from one location."
"The best feature in Microsoft Intune is zero touch deployment, which allows me to automate many tasks compared to manually installing Windows and applications one by one, making it easier to enroll devices with Autopilot and pre-deploy applications."
"Microsoft Intune is brilliant for scalability and is excellent for scaling purposes."
"The biggest benefits of Intune are the ability to push changes and the added security. When we moved forward with Defender, we onboarded all those machines automatically. That helps dramatically. For a while, we were left with machines that weren't protected. We could see where people had done things they shouldn't have done, and Defender saved our skins a few times. It didn't happen a lot, but it happened enough that it made us glad we made that decision."
"The most valuable feature for us is the security, including risk analysis and patch management."
"Intune is a very good cloud solution for managing devices."
"The interface is user-friendly, and the reporting tool works in real-time."
"The most valuable feature is safety."
"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."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"Without ISL Online, I would not be able to work from home."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"We can also monitor our systems at any time from practically anywhere."
"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."
"Just being able to dial in on a clients server is all I need, and it reconnects automatically when there are connection issues."
"Quite literally, without TeamViewer's capabilities, we wouldn't be able to run our business."
"I use this almost daily to log into users computers across the nation, enabling me to troubleshoot issues much quicker than trying to talk someone else through things and allowing for nearly instantaneous troubleshooting."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"TeamViewer is a step ahead of solutions like, for example, AnyDesk."
"The most valuable feature of TeamViewer is its ease of use."
"We've been very happy with the solution over a number of years."
"The dashboards they have are good."
 

Cons

"Intune's server management could be better. If it could incorporate more features from System Center into Intune's Configuration Manager, it would be beneficial."
"The way the apps are getting deployed, the checkboxes for deleting previous versions are actually creating more conflicts than fixing problems."
"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."
"They can improve their MAM policies a little bit more and make them more granular. They should include more granular group policies. They are there, but they need to be more granular. Its stability should also be improved. It is not very stable. Sometimes, it shows some inconsistencies across tenants."
"There are some areas of improvement for Microsoft Intune, including faster policy sync so changes can apply quicker, a simpler interface, better reporting with more details and clear insight, improved troubleshooting, clearer error messages and logs, and stronger support for macOS and Linux, alongside better cross-platform features."
"I would like some integration with the Microsoft reporting platform Power BI."
"If you're looking forward to deficiency, I'd say that the Endpoint Manager support at the lower levels is poor."
"I cannot think of any particular features which I consider to be most valuable."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"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."
"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 have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"It would be helpful if they had iSupport for supporting Apple phones."
"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."
"I would like to be able to access and manage all brands of smartphones."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"When clients have a newer version installed and we only have a license for version 8, there are issues."
"I am not sure about all the features of TeamViewer, but if they have no voice communication or file transfer features they should add them."
"TeamViewer has a legacy and may not be using the latest UI trends."
"TeamViewer is expensive, and you get a limited number of connections for your money."
"We have a consultant that helps us do the virtual aspects of TeamViewer."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"The only thing I wish for is a better price for small users."
 

Pricing and Cost Advice

"This cost is approximately $30 USD per user per month."
"Even if they charge a premium, they aim to provide equal value."
"They have categorized the licenses according to the size of the business. So, if it's a smaller organization, we can choose the license accordingly. If it's a big organization, then we can choose accordingly. Everything is clearly mentioned, and we can decide. It's suitable for all kinds of infrastructure, and that's very goo"
"All security solutions worldwide are expensive. Microsoft has allowed a small scale of features within Microsoft Intune for cost-efficient solutions. If you want the full suite, you need to invest more to gain better security features."
"I am not that aware of the pricing, but as compared to other MDM solutions, Microsoft is providing a lot of things at the organizational level. So, it is quite reasonable as compared to other MDM solutions."
"We don't get Intune as a separate module. Most of the time, we use it within an enterprise agreement like E3 or E5. Those licenses are at a good price, but what is annoying is that every single year they go higher."
"The cost is handled through our Office 365 license, so I have yet to be able to compare it directly with other tools in its class."
"The product is relatively pricey, but considering its benefits, I'd say it's fair. The benefits outweigh the expensive licensing fees, especially for large organizations, but medium-sized and smaller businesses may be unable to afford it."
"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's price is cheaper than some other similar solutions. We have licenses for our users."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"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."
"I used the free version of TeamViewer."
"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."
"TeamViewer is $600 or $700 per port per year..."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
