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

"It works well if you have a Microsoft environment."
"I have been using the Enterprise Application Management feature of Microsoft Intune, which enhances abilities when it comes to app discovery, deployment, and automatic updating."
"The overall user experience is quite nice. I have no complaints from end users regarding their devices enrolled in Intune."
"Application deployment and keeping the devices secure no matter where they are, by having this cloud solution — that has been great."
"I like the fact that it's integrated with the rest of the Microsoft products, so customers can manage it from their Office 365 portal or Azure portal."
"Intune has automated the deployment of patches and applications, which is more efficient and easier. It allows us to deploy applications, packages, Windows updates, and security updates like BitLocker encryption more efficiently and easily."
"If I assess Intune's user experience, I would say it is perfect and simple."
"One of the standout features of Intune is its seamless accessibility to work data, eliminating the need to be tied to an office or a desktop."
"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 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."
"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."
"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."
"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."
"The most valuable feature of TeamViewer is user-friendliness."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
"TeamViewer is a scalable solution."
"The product is easy to install."
"The most valuable feature of TeamViewer is its ease of use and beneficial remote access."
"With an image, you can see immediately what's going on. You can run some tests. Without the solution, you need to do everything by telephone. It's not even thinkable."
"It was worth the investment. You can do file transfers and video calls with it. You can do a lot of copy paste stuff. E.g., if I have a file and want to place it on somebody's machine, I can just copy it off of mine and paste it right on their machine. I don't have to put it in a Dropbox account and have them log into it to pull it off. I can do all that right through TeamViewer. When you're looking at the TeamViewer screen, you think you are working on your own machine."
 

Cons

"Microsoft Copilot in Microsoft Intune is absolutely useless for protecting my environment."
"Intune should improve its software inventory to provide better metering of which software is used throughout the company. This is especially needed for reporting third-party software solutions."
"Reporting needs to be better. Sometimes, it is way too slow, and it is not even accurate."
"Microsoft Intune could improve in reporting data for endpoints and fleets. Enhanced capabilities to run queries and gather specific device data to identify trends or issues would be beneficial. The feature parity for MacOS and handling devices from an MDM perspective is not comprehensive. Consolidation of these functionalities within Intune would simplify processes and finances."
"I rate Microsoft customer service six out of 10. While some technicians go above and beyond, there is inconsistency, and connecting with the most helpful representatives is occasionally challenging."
"It would be interesting to integrate the server side of Intune. Some group policy updates we have on the Windows Server side and possibly some on the client side could also be included."
"It would be beneficial to have a more straightforward understanding of Intune's capabilities, presented in a simplified manner."
"Intune is not the most user-friendly mobile device management platform available."
"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."
"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."
"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."
"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."
"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'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."
"The product's expensive nature is an area of concern where improvements are required."
"The business interface is clunky and not well-documented."
"I'm not sure if they provide good quality audio alongside screensharing."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"One thing I have noticed is that TeamViewer does not work so well when the machine you are trying to connect to remotely is not running the same version as your machine."
"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."
 

Pricing and Cost Advice

"As a partner, we always look for how we can generate more revenue from a consulting point of view, but I do not see any complaints from the customer side regarding pricing, so they are satisfied with it."
"The pricing is good because customers are not complaining about it."
"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."
"The price could be better."
"Consider the Microsoft Enterprise Mobility Suite rather than choosing specific sub-components, e.g. only Microsoft Intune."
"Generally, we get favorable discounts, so it's not too bad. Obviously, we're looking at decreasing those wherever we can to bring value back to the public purse because it's all charity based. It's all publicly funded."
"Our enterprise agreement includes Microsoft Intune at no additional cost."
"The E5 license is 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."
"The solution's pricing is reasonable."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"I used the free version of TeamViewer."
"We are using the free version of TeamViewer."
"The cost is in the thousands of dollars per year."
"We are using the standard free version of TeamViewer."
