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

"Implementing Microsoft Intune has provided a more streamlined and consistent method for device management across our multiple domains, effectively consolidating our administrative efforts."
"I would say the biggest benefit is the single-pane view. There's no jumping around multiple UI's to do your overall management."
"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."
"One of the most valuable aspects of Microsoft Intune is its seamless integration with Azure Active Directory, offering capabilities akin to Group Policy Objects."
"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."
"Autopilot is the most valuable feature of Microsoft Intune."
"Conditional access has helped us tailor and enforce our security policies in the mobile space."
"Microsoft Intune brings all our endpoint and security management tools into one place, acting as a comprehensive solution where we can manage numerous devices and configuration profiles, and block specific URLs, among many other capabilities."
"We can also monitor our systems at any time from practically anywhere."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable feature is safety."
"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."
"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 like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
"It's a user-friendly product."
"The quality of the call and the quality of the sharing have been excellent."
"It saves trips to customer sites, which saves time. I am able to get in there remotely and fix things."
"The product is quite stable. The performance is good."
"I like that it helped a lot, even with low bandwidth network connectivity. For example, while I was traveling, sometimes there were requirements for me to join a TeamViewer session and provide technical support. I was able to do that without much of an issue. It is also a secure solution."
"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."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
 

Cons

"There could be some kind of feature that supports a workgroup environment or a separate environment without the Entra ID."
"Sometimes the syncing is inconsistent. I'm confident that the devices are checking in every eight hours, but sometimes the devices aren't picking up the settings as quickly as I would expect."
"Areas for improvement in Intune include expanding support beyond Samsung devices to accommodate other Android manufacturers like Redmi and Motorola."
"Intune does not provide real-time visibility."
"The pricing could be improved."
"Currently, BitLocker does not support BYOD enrollment, which is a product limitation."
"One thing that could be better in Microsoft Intune is the file size, as it is quite large at times."
"There are a lot of updates coming from Microsoft that suddenly affect our security policies."
"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."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"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 be able to access and manage all brands of smartphones."
"There could be a section in the menu describing the new features and changes."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"I would like it if the trial version of TeamViewer allowed you to have a connection for much longer."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"TeamViewer can improve by making the interface more user-friendly. It looks very basic, they can make it more modern and easy to use."
"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."
"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."
"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."
"The business interface is clunky and not well-documented."
"They should release features such as Augmented Reality into both plain and standard versions of TeamViewer."
 

Pricing and Cost Advice

"We work with the subscription rather than a server license. I think it's economical this way because we don't have to have a server license for that, and I think that works in our favor."
"The clients pay for a license and each can have a different type of license, such as an E3 or E5."
"The licensing costs we leave up to the customer and these vary from one to another."
"With one user base license, we can use Intune for up to five devices. However, with Soti MobiControl, each license is tied to a single device, meaning one license is dedicated to one device only."
"The pricing is competitive, but it is not cheap."
"Microsoft Intune is pretty reasonable. We have difficulty with Azure, which is probably why we have not put many assets in Azure. Everything we put there is very expensive."
"Consider the Microsoft Enterprise Mobility Suite rather than choosing specific sub-components, e.g. only Microsoft Intune."
"I am satisfied with the pricing."
"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."
"We are using the standard free version of TeamViewer."
"We have a permanent license and the price is reasonable."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"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."
"There is no license needed to use TeamViewer."
"The solution's pricing is reasonable."
"There is a free and paid version of this solution. I am currently using the free version."
"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."
