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 reporting and analytics features in Microsoft Intune have been a lifesaver."
"The biggest benefits of Intune are the ability to push changes and the added security. When we moved forward with Defender, we onboarded all those machines automatically. That helps dramatically. For a while, we were left with machines that weren't protected. We could see where people had done things they shouldn't have done, and Defender saved our skins a few times. It didn't happen a lot, but it happened enough that it made us glad we made that decision."
"Microsoft Intune has been a time saver and reduces the time and effort IT admins have to invest."
"When a user receives the machine, sets it up, and turns it on, it connects to the domain and begins installing software, becoming ready within approximately half an hour, which represents a significant time savings for IT departments."
"The feature I like the most is that we can perform remote tasks. If we want to retire or wipe out personal data or corporate data from a device, we can use Microsoft Intune remotely, and with the click of a button, data is removed automatically. Nothing needs to be done from the end-user side."
"Microsoft Intune has helped us by improving our security posture, leading to fewer security problems, and helping us understand where we have issues."
"Overall, I like Intune as a solution and would rate it nine out of ten."
"It is absolutely a positive investment."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"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 most valuable feature is safety."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The solution is very stable. We've never had a problem with it."
"It saves trips to customer sites, which saves time. I am able to get in there remotely and fix things."
"TeamViewer Business has positively impacted my organization by boosting efficiency since you do not need to be physically available to the client to troubleshoot or help them."
"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."
"TeamViewer has been one of the easiest, right off the bat products, that we have employed at the college. We have had no issues. It's been one of the easiest solutions to pick up."
"The most valuable feature of TeamViewer is its ease of use."
"TeamViewer Business has positively impacted our organization by reducing the time of the TAT for resolving issues for end users, which has really helped us."
"The best feature is the remote access and being able to control another person's computer when you're showing them something, or teaching them how to do something during training, or fixing a problem they're having."
 

Cons

"The Mac integration has room for improvement."
"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. Some features haven't been updated in a while, and Microsoft doesn't seem interested in developing them. Unless you talk to an engineer, you don't know whether there will be an update."
"Intune doesn't provide much control over Windows servers. It's something we struggle with."
"Deploying an app can be a complex process due to dependencies."
"Policy and app deployment should be faster, as it currently takes between minutes to hours to apply, with an average of one hour."
"The initial setup is a little bit complex."
"I have experienced downtime, bugs, and glitches. I rate it a seven because when we have bugs or instability in Microsoft Intune, we need to wait for the backend from Microsoft Intune to resolve issues and we can't deliver solutions to clients because we need to wait for action plans and related processes."
"Reporting in Microsoft solutions is pathetic. With Intune, I'm getting a free inventory tool, but I don't get a reporting tool. When I go to Intune, I can see one machine's entire data in terms of the hardware and the software running on it, but I cannot generate a report for all the machines in the organization. The reporting is the only feature holding back the functionality that is already there."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"They need to better advertise the features."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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 is a paid version of this solution with more features available. However, they should provide more free features to the user, such as factor authentication."
"It should have ability to display notes in the computer list."
"We'd like to be able to work from mobile to desktop and vice versa. We'd like more mobility."
"The file transfer functionality crashes sometimes."
"TeamViewer could improve by having a cloud version. Having the solution on the system could cause some cyber security concerns with data."
"TeamViewer could be more secure."
"You can't configure multiple, unattended control passwords on the Mac. On the Mac, there's only one. On Windows, there are multiple unattended control passwords. I have people in different departments. My infrastructure people need to control a server and my developers may need to go into that same server. But I don't want them to have the same password... on the Mac, it can be done but it's extremely clunky and problematic."
"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."
 

Pricing and Cost Advice

"It comes with the E5 plan. We bought the E5 plan from Microsoft."
"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."
"It's a part of Microsoft 365 and E5 licenses. Microsoft's strategy of making every feature in Microsoft Intune paid needs optimization. Remote control is one of the basic features, not a luxury feature, yet we must pay for it. I"
"Its pricing seems reasonable."
"Microsoft Intune has a user-based subscription model. You can go for a monthly or a yearly payment."
"While I don't have access to high-level financial information, I believe we have achieved lower costs with this implementation."
"While Microsoft charges for actual usage, it lacks discount options."
"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."
"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 free version of TeamViewer."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"I used the free version of TeamViewer."
"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 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."
"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 solution's pricing is reasonable."
"It has probably saved us several thousands of dollars because we have quick access anywhere. We don't have to worry about finding people onsite or arranging conference calls. We also save time and money with it because we don't have to send somebody onsite to troubleshoot."
