Enables management of multiple operating systems with a single license
The best feature is that it's a Microsoft product, so if anything goes wrong, we get quick support for anything required. Remote system functionality allows us to sit anywhere and take control of any device via remote management. We can enhance security for clients' laptops with built-in Microsoft Defender, which is available with the Microsoft Intune license. We use it for reporting purposes through endpoint analytics. When pushing scripting, there are two types available: remediation script and reservation script. Through endpoint analytics, you can push defender policies to clients. It helps with reporting, inventory updates, and monitoring tenant status health.

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 support has transformed my work and now saves time with fast, secure file transfers
What I appreciate about TeamViewer Business is the reliable and secure connection experienced during file transfers or troubleshooting processes, even when we have to restart the PC; we are still able to connect to the customer quickly. TeamViewer Business offers a free version for both personal and business use. The free version actually covers all the features needed for secure remote connection, which is one of the positive aspects I have experienced. The secure connections and great file transfer feature are super fast and secure, with reliable features during the process of reconnecting and connecting back to clients. Back in 2009 and 2007, the internet did not have the faster features it has today. TeamViewer Business's file transfer feature has made things easier. Instead of downloading a file from a source like HP.com, we just have to transfer the file from our system to the customer securely and quickly. Many technical support people have benefited from that feature, which I find very reliable.

Quotes from Members

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

Pros

"The ability to block and erase remote devices is valuable to us, especially when those devices are lost."
"Overall, the best features of Microsoft Intune are its ease of management and robust security protocols, which are what I value most about it and how it stands out."
"I like how Microsoft Intune lets me lock down the email profile and make it accessible only on certain devices."
"Within Intune, managing policies and having a consistent way to manage devices is valuable."
"We already use a lot of Microsoft products in our company, and therefore, it made sense to also use this product."
"I would rate Microsoft Intune a nine out of ten."
"The security compliance capabilities make it widely adopted across organizations."
"Intune's feature that I have found most valuable is its auto-pilot feature."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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 like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"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."
"The most valuable feature is safety."
"The solution is scalable."
"The quality of the call and the quality of the sharing have been excellent."
"It is easy to use and has a pretty good UI."
"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."
"There have been a couple of times with the handy remote access feature, where I have been asked for something at eight o'clock on a Thursday evening and it is on my desk machine, but I am driving back to my office. With TeamViewer, I can just stay at my home machine, connect to my work machine, and get the data needed without having to drive back across town."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"The most valuable feature of TeamViewer is user-friendliness."
"It's very beneficial and time effective on how we are able to provide quick support. We've quadrupled our effectiveness as an IT support because we have cut down all that unnecessary travel time, even between floors."
 

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."
"I rate Microsoft support between six to eight. The support often involves third parties hired by Microsoft who are knowledgeable, but sometimes the help I receive is not adequate."
"Intune does not provide real-time visibility."
"I would like to see better integration with Microsoft."
"Reporting could be improved. It needs to be more expensive and robust."
"For an existing customer who has an SCCM, it would need to be upgraded to an MECM first before I can introduce Microsoft Intune."
"While the ability to deploy applications at startup is reliable, the policy-based application deployment method has not reached the same level of consistency."
"Customer service used to be better, but as we are nearing the end of the contract, the focus on investing in us as a customer has diminished. It is what one would expect in such a situation."
"I would like to be able to access and manage all brands of smartphones."
"They need to better advertise the features."
"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."
"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."
"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."
"There could be a section in the menu describing the new features and changes."
"We access the solution through a VPN, which improves our security. However, earlier this year, around the beginning of March, a CVE in the TeamViewer client allowed remote connections to other network systems, which was concerning. You could have unintentionally gained admin rights if you didn't update TeamViewer promptly. It's crucial to always keep it updated to prevent such issues. The tool should consider implementing two-factor authentication to improve such security holes. It should also integrate good security updates, which should be implemented automatically."
"This solution could be improved by offering more flexibility in terms of usage."
"Support for mobile devices from Linux has been missing since the Native client was rolled out. This was a nice option, especially when trying to walk somebody who was struggling to understand something on their phone."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"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."
"On occasion, when remote connection process can't connect to a machine, the error messages aren't always helpful to tell you why you can't connect, as the message doesn't help troubleshoot whether it is too slow, too much interference, etc. I usually have to run to another computer and figure out what is going on, then restart it. The diagnostics could be improved."
"They could give more information about using certain kinds of applications for secure transactions, such as secure file transfers."
"A feature that they could add is chat with sound to talk."
 

Pricing and Cost Advice

"Its price is in the medium range. It is acceptable because you're paying for the features. I am not aware of any additional costs."
"It's affordable. In comparison to the competitors, the price depends on what features you need from Intune, but it's affordable. There are no hidden costs, but there are some features that go for a premium price. Those are the add-ons for which you have to pay extra."
"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."
"It is not expensive."
"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 purchase of the product was handled by someone else."
"It is reasonable. When you have Microsoft 365 E3 or E5 license, it is already licensed in that license. So, you could say it is free."
"I would rate the price a four out of ten with ten being the most 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."
"The version of the solution we are using is free."
"We have a permanent license and the price is reasonable."
"It would be nice if it is cheaper."
"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."
"TeamViewer has multiple licensing options."
"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."
