Features: TeamViewer Business provides a rich feature set, including session recording, advanced security with two-factor authentication, and seamless integration capabilities. It's noted for its automatic reconnection feature, cross-platform compatibility, and efficient file transfer, enhancing workflow. ISL Online offers essential features such as unattended remote access, focusing on reliability and simplicity with easy-to-use operations that support cloud or on-premises deployment.

Room for Improvement: Feedback points to TeamViewer Business needing clearer licensing, better Linux support, and UI enhancements.

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

"Microsoft Intune brings all endpoint and security management tools into one place, and for app discovery, deployment, and automatic updating, it's reliable."

"I would rate Microsoft Intune a nine out of ten."

"This product offers an alternative solution to other UEM (Unified Endpoint Management) solutions."

"As an IT administrator, I appreciate Intune's ability to implement granular device-level policies for our organization's employees."

"The most valuable includes managing everything from a single console."

"A valuable feature is user enrollment, where users can enroll their devices in their organizations themselves."

"Intune simplifies compliance. The ability to manage software updates and policies on endpoints has helped us meet contract requirements."

"The features I found most valuable in Intune are its user visibility and troubleshooting options."

More Microsoft Intune pros

"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."

"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."

"Setting up the solution is easy and there's no maintenance involved."

"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."

"Good communication is a key to good business and ISL helps a lot."

"I personally really appreciate the file transfer feature as it is really easy to use."

More ISL Online pros

"If someone is looking for a remote connection and support solution, this is a good choice."

"The solution is stable, reliable, has no bugs or glitches, does not crash or freeze, and the performance is good."

"The new two-factor authentication is a very good addition to security."

"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."

"It is very easy to configure and very easy to use."

"TeamViewer Business has positively impacted my organization by helping us resolve critical issues within the four-hour SLA contracts we have with clients, avoiding penalties associated with delays."

"The most valuable features of TeamViewer are the high performance and it is not complicated to use, neither for me nor for the one I'm helping."

"TeamViewer has a good interface."

More TeamViewer pros

Cons

"However, I dislike how it lags sometimes. I cannot work on multiple processes at the same time."

"It would be great to see on-premises mailboxes and for the solution to have geofencing capabilities."

"I would like to see the ability to deploy custom packages as a Windows 64-bit package, as opposed to the Windows 32-bit, which is the only one available now."

"There are some issues using the solution with macOS and iOS, and it offers limited granular control with them. Intune works better on Windows and Android."

"Reliability is something that I feel there is a tad bit of concern. The only point is that we need to sync multiple times to get something pushed through."

"One major concern I have is user friction. When you enforce many policies and people log into apps like Microsoft Teams or Outlook, they encounter numerous MFA and other policies."

"We faced issues with macOS support. The product should have better inventory and asset management."

"There are a lot of updates happening on Microsoft."

More Microsoft Intune cons

"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."

"I would like to be able to access and manage all brands of smartphones."

"They need to better advertise the features."

"It would be helpful if they had iSupport for supporting Apple phones."

"There could be a section in the menu describing the new features and changes."

"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."

"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."

"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."

More ISL Online cons

"The solution could include more AI (Artificial Intelligence)."

"Quick User Switching has a very nasty tendency to render the screen output unstable."

"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."

"But still, I think the price factor for small business."

"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."

"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."

"Sometimes when I am in a low network area, I face issues with connectivity while using TeamViewer, so definitely in that scenario, it should operate better over low networks."

"It's not the program itself that's an issue, but there is a need for some better documentation on how to use the web portal Management Console. That seems to be a bit lacking in directions, if you aren't paying attention and you don't know what to do. Better documentation would make it a little bit easier to set things up in different groups and share groups between people."

Pricing and Cost Advice

"The price is very reasonable."

"It comes as a bundle, so you do not really know what the prices are. Microsoft does not break it down to the user cost for us. It is just bundled with our E5 license."

"For Microsoft 365 E5 clients, cost is not an issue as this product is one of the benefits."

"With our standard E5 agreement with Microsoft, there have been no pricing concerns. Introductory professional services, like a fast-track service, were included with our E5 membership, and there have been no additional costs."

"Intune is moderately expensive. You can get the license bundled with Office 365 E3 or E5 licenses. The E5s are a bit expensive, but you get some cheaper solutions with Intune."

"It is cheap, but as compared to Google, it is costly. Google is cheaper, but quality-wise, Microsoft Intune is better."

"Microsoft Intune's costliness stems from licensing fees and the overhead associated with its management, user experience, and device remediation."

"Microsoft Intune's pricing is reasonable."

More Microsoft Intune pricing and cost advice

"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 has multiple licensing options."

"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."

"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."

"We're using the free version. We do not pay any licensing fees."

"The solution's pricing is reasonable."

"The cost is in the thousands of dollars per year."

"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."

"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."
