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

"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"The solution appears to be stable and scalable."
"Its protection policies are most valuable. It protects mobile devices as well as individual apps. It is pretty scalable, and its documentation is also pretty good. It is also pretty straightforward to deploy."
"The tool's most valuable feature is Autopilot."
"The most valuable feature of Microsoft Intune is its scalability."
"Microsoft Intune has transformed my organization; we are managing to scale the Intune deployment across all our regions efficiently, and it works perfectly for our needs."
"The standout features of Intune are its excellent mobile device management and highly effective application management capabilities."
"Without Microsoft Intune, it would be extremely challenging, if not impossible, for a large company to send out computers to users and have them set up and ready to use right out of the box in a remote location."
"I personally really appreciate the file transfer feature as it is really easy to use."
"Setting up the solution is easy and there's no maintenance involved."
"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."
"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."
"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."
"We can also monitor our systems at any time from practically anywhere."
"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."
"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."
"TeamViewer allows us to do multiple controllers on a Host, which is great. We have a lot of Macs in our organization, and TeamViewer being cross-platform is a good thing."
"The usability and graphic interface stand out for me because it is very easy to understand, with upper bars, all the features, and the file transfer functionality."
"The product is quite stable. The performance is good."
"It saves trips to customer sites, which saves time. I am able to get in there remotely and fix things."
"We also use it a lot for remote site assistance. We've set up our internal authentication for unattended access to our remote sites. That makes it very easy and convenient to remotely connect with our users and our client machines whenever we need to. It's set as a direct, secure connection. As long as the station has internet access, we can see it and it makes remote support very simple."
"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."
 

Cons

"The installation could be improved to be simplified."
"While no specific feature requires immediate improvement, the ongoing expansion of reporting and inventory capabilities promises to enhance its utility."
"The pricing could be improved."
"We are facing issues with Apple products. With macOS and iOS, there are some difficulties with the updates because we cannot get full control of Apple products. In the case of Windows, it is fine, but in the case of Apple, we have some difficulties. We cannot control everything through Intune."
"Once it's configured it is unobtrusive, but it does take some hands-on to configure and deploy it properly."
"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."
"More integration with monitoring tools is needed."
"It would be great to see on-premises mailboxes and for the solution to have geofencing capabilities."
"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."
"There could be a section in the menu describing the new features and changes."
"They need to better advertise the features."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"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."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"TeamViewer Business's scalability is bad because it's very expensive."
"TeamViewer could work on performance latency in slower internet connections by optimizing screen refresh rates during remote sessions, especially when transferring large files or using graphics-heavy applications."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"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."
"It should have ability to display notes in the computer list."
"Sometimes it gives problems, with the button not working, and I was unable to log in."
"It becomes complicated to switch from one monitor to another for different windows."
 

Pricing and Cost Advice

"The price of Intune is included with the license for Office 365, so we don't have to pay anything extra for it."
"Microsoft Intune is included in the E5 license at no additional cost."
"The tool is cheaper than our company's other MDM tools."
"Its price is fair. It's a normal price. It isn't too expensive or too cheap."
"Based on the features that it gives, it is cost-efficient. It is not necessarily on the expensive side of the scale. It provides a hefty number of features that any organization would want. It is in a good price range."
"The cost is somewhat on the higher side, particularly when considering certain price points, especially in markets like India."
"It's bundled with Business Premium and an E3 license, which is beneficial. If you have to pay extra, it's pricey, but with the bundled package, it's acceptable. They recently increased the Business Premium pricing, which we don't appreciate. The price increase and yearly commitment are causing some problems for us."
"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 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 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."
"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."
"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."
"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."
"We use the free version of TeamViewer."
"We have a permanent license and the price is reasonable."
"I used the free version of TeamViewer."
