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

"Intune's feature that I have found most valuable is its auto-pilot feature."
"The thing I appreciate most about Microsoft Intune is that the management of the devices was very simplified. We have all machines connected to it at all times, whether they are in the office or working from home."
"I like how Microsoft Intune lets me lock down the email profile and make it accessible only on certain devices."
"Intune device restriction policies enable me to enforce limitations on the device, like blocking the mobile camera or restricting the employees from using and inserting USB devices, including thumb drives and flash drives."
"Microsoft Intune is a tool designed for enterprise customers to protect enterprise data from leakage or sharing."
"The ability to block and erase remote devices is valuable to us, especially when those devices are lost."
"For the price, the features included with Microsoft are appealing."
"Our bank's most valuable Intune features are centered around the dedicated device concept."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"I personally really appreciate the file transfer feature as it is really easy to use."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable feature is safety."
"We can also monitor our systems at any time from practically anywhere."
"It's pretty easy to use. Just key in an ID and password and connect. For meetings, just enter the meeting ID and connect."
"TeamViewer is stable."
"TeamViewer has a good interface."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
"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."
"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."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
 

Cons

"The add-ons must be integrated into the solution."
"Historically, Group Policy has simplified the management of various items, such as printer and drive mappings and while Intune offers workarounds, it lacks native support for these functionalities."
"I expect Microsoft Intune to have more features in the cloud because there are two major functionalities that we need to be added. This is software metering and license management. These functionalities, for now, must be on-premise. For this purpose, we have set up a SQL Server and I hope that in near future this option will be in the cloud in Microsoft Intune."
"The mobile management is good for iPhone and iPad, but the Apple Mac management needs improvement. That is probably because Microsoft does not have low-level access to Apple Mac hardware. If you are doing basic things, it is okay, but if you want to image Apple Macs and do things like that, then Jamf is much better."
"From my level of analysis, the feature I would prefer to see added to Microsoft Intune is extensive support. Anything that helps to diagnose the problem and solve it would be useful."
"The time we have to wait to deploy policies has room for improvement."
"Integration with Mac devices requires some improvement."
"When we implemented Intune, it would have been helpful if Microsoft had provided some videos or data about Intune."
"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 be able to access and manage all brands of smartphones."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"They need to better advertise the features."
"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."
"There could be a section in the menu describing the new features and changes."
"If they could figure out a little better solution for the iOS stuff other than just a screen share, even though it's an Apple thing, and Apple doesn't like to give up control of their devices. If they ever got to that point, and I could manipulate an iPad or iPhone, that would be awesome. Since we have a bunch of iPad users who are struggling with doing different things, it would be nice to be able to just jump on and actually show them, "Here, do this, this, and this." Similar to what we do with the laptops, e.g. for training."
"Sometimes it lags."
"Every now and then you'll get a silent crash and you relaunch the application. But it happens no more than with anything else in the Windows environment."
"Voice communication and screen communication or face-to-face communication could be improved."
"I would like to see something like a TeamViewer mobile application for iOS or possibly Android. I think this would be fantastic given how technology is evolving today. It would be beneficial to use it with your smartphone."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"TeamViewer Business can improve in terms of price and the complexity of licensing, which is a drawback, especially for smaller teams or casual users due to frequent license changes and forced upgrades."
 

Pricing and Cost Advice

"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."
"The pricing needs improvement."
"There are licenses required for this solution. We enable licenses on the devices we need to manage."
"Our enterprise agreement includes Microsoft Intune at no additional cost."
"Intune is inexpensive. It also comes bundled in some Office 365 licenses, so you can choose to purchase it separately or as a package."
"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"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."
"Our Office 365 Business Premium license, including Office 365 and Intune Management, offers excellent value."
"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 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."
"The cost is in the thousands of dollars per year."
"We have a permanent license and the price is reasonable."
"TeamViewer pricing is reasonable... The simultaneous controller licensing model of TeamViewer - compared to LogMeIn’s controlled Host licensing model - seems to benefit us so far. We’re currently saving about 30 percent on licensing cost... The savings from licensing have been eaten up by the soft costs involved in dealing with and working around TeamViewer’s deficiencies in allowing granular control by multiple controllers, and the issues with the various settings that are missing on the macOS Host."
"We are not using the solution for commercial use therefore it is free to use."
"We are using the free version of TeamViewer."
"We are using the standard free version of TeamViewer."
"We use the free version of TeamViewer."
