Centralized endpoint security has improved and supports hybrid work and BYOD policies
Regarding what I dislike about Microsoft Intune and its downsides, I would say that more Mac controls are needed because we have limited Mac and Linux control. When comparing controls and policies between Windows, Mac, and Linux, Windows has almost everything you can think of, while Mac and Linux have limited types of control. You cannot implement certain things on Mac and Linux that you can on Windows. The limited controls are a major issue. Additionally, if Microsoft could find a way to embed servers into Microsoft Intune, that would be beneficial. Microsoft Intune is not really designed for servers or Windows servers. It is more tailored towards Windows 11 and Windows 10 operating systems. Windows servers are not fully supported. Enterprise organizations usually have both servers and endpoints, which are users' workstations. For servers, most people look for other solutions such as SCCM, which is Configuration Manager. However, SCCM is what Microsoft Intune is trying to replace. Both SCCM and Microsoft Intune belong to Microsoft. Microsoft is trying to transition organizations into Microsoft Intune, the native cloud solution. However, because this update is still in process, servers are not fully compatible with Microsoft Intune and cannot be managed by it. The current policy that has emerged from issues with clients is what they call co-management, which is relatively new, and I do not know if adoption is significant. Many legacy or older customers who have been using these products for decades still have SCCM. When it is time for them to manage their Windows devices, they use what is called cloud attach. Cloud attach is a term whereby your SCCM is connected to your Microsoft Intune. Most people do not know about it, but I have deployed it for several organizations. Cloud attach and co-management work together so that your device is in SCCM, but some policies are pushed from Microsoft Intune. It is like two different solutions working hand in hand. That is what they call co-management. Microsoft Intune does not bring all of your endpoint and security management tools into one place, which is the goal and how it should be. However, as I mentioned, servers are not included. If we talk about end users, Microsoft Intune does bring all your devices together. In a typical enterprise environment, you have end users with workstations, laptops, company-issued phones, and bring your own devices. You can create policies for all of these. However, for the backend, your servers do not have much coverage. Servers are not really covered by Microsoft Intune in that way.

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

"Intune does consolidate all endpoint and security management tools into one place, making everything easier to manage."
"The overall user experience is quite nice. I have no complaints from end users regarding their devices enrolled in Intune."
"Intune's integration with Defender and other security solutions is valuable because it offers a view into different security vulnerabilities and enables us to secure them more effectively."
"The most valuable feature of Intune is the user-friendly portal for end users."
"Microsoft Intune simplifies device management by replacing the traditional method of installing OS, joining a domain, and configuring everything manually."
"In terms of technical support, you will get an immediate response."
"Conditional access helps me control uncontrolled access."
"We are a Microsoft 365 E5 customer and the product promises the capabilities that we need and is available without additional cost."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"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 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 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."
"Without ISL Online, I would not be able to work from home."
"I personally really appreciate the file transfer feature as it is really easy to use."
"We use TeamViewer for our help desk to manage and troubleshoot remotely."
"Ultimately, however, even with all of its warts and problems, it's still the best, most reliable and most affordable remote control product, at least for our environment."
"Our computers are spread amongst six physical locations, and TeamViewer reduces the need to travel to those offices to help staff."
"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."
"The most valuable feature has been the ability to give control to others for support purposes."
"Their tech support is really good."
"The dashboards they have are good."
"The solution is user-friendly and very flexible."
 

Cons

"Microsoft Intune is a very strong platform, but there are still some areas where it could improve."
"While no specific feature requires immediate improvement, the ongoing expansion of reporting and inventory capabilities promises to enhance its utility."
"I find the price for Microsoft Intune too high, which represents an area for improvement in Microsoft's pricing model."
"Sometimes, updating a client policy is very difficult. This needs to be improved."
"For an existing customer who has an SCCM, it would need to be upgraded to an MECM first before I can introduce Microsoft Intune."
"There are items that require improvements. One is the controls from iOS."
"One thing that could be better in Microsoft Intune is the file size, as it is quite large at times."
"There is room for improvement in integrating additional features such as Purview and SharePoint activities into Intune."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"I would like to be able to access and manage all brands of smartphones."
"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."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"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."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"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."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"There is a paid version of this solution with more features available. However, they should provide more free features to the user, such as factor authentication."
"There have been a few times when TeamViewer has been down globally, so that’s definitely an issue for consideration."
"They could give more information about using certain kinds of applications for secure transactions, such as secure file transfers."
"The only thing I can think of is a quick-deploy / auto-installer for the end users."
"I believe latency can be optimized, and security control sometimes goes over the top and feels excessive."
"By comparison, TeamViewer is a complete mess; the way they do it is a total nightmare, and it does not work well."
"We have a consultant that helps us do the virtual aspects of TeamViewer."
 

Pricing and Cost Advice

"It is average. Some of the costs are quite high depending on what the customer currently uses, but overall, it is not bad. I would not say that I would not recommend Intune based on the cost. I definitely would, but they can definitely improve on the cost. So overall, its cost is not bad."
"The pricing needs improvement."
"The pricing is not cheap, especially with inflation. They've had to increase their prices. It's not excessive, but alright."
"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."
"There is a license required to use this solution. However, it was part of a bundle package. Microsoft Intune is far less expensive than other solutions, such as Workspace ONE."
"Intune is linked with Microsoft. We can deploy the Microsoft E365 license to users by Intune. There are different types of licenses, such as device administrator licenses, E5 licenses for device enrollment manually, and P1 and p2 licenses for device enrollment automatically. These are the licenses required for the administration."
"The cost of the license and the features are justified for myself as a technical person."
"There is a license required to use the solution. If you're core users in Office 365, for example, you have Outlook email and E3 license, this is only email. You have to buy an EMS license to have Microsoft Intune. It is expensive."
"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."
"The version of the solution we are using is free."
"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."
"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 are using the standard free version of TeamViewer."
"I used the free version of TeamViewer."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"We are using the free version of TeamViewer."
