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

"For our clients, the conditional access feature along with different compliance policies that they can set is valuable."
"Third party integrations are very convenient to use with Microsoft Intune."
"Intune significantly simplifies application deployment, mobile application management, and policy enforcement, such as restricting user access to specific applications, thereby enhancing overall environment security."
"Intune's most valuable features are its device management capabilities, particularly its centralized integration with other Microsoft stack components."
"I would recommend Microsoft Intune to others; it is a very good and scalable solution."
"Configuration profiles, remediation, scripts, and auto-pilot features are very good."
"The stability of Microsoft Intune is good."
"Conditional access helps me control uncontrolled access."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"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."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
"The most valuable feature of TeamViewer is the ability to remote into another device."
"One of the best features of TeamViewer Business is the security and respect for privacy, since you can connect to a specific computer using a unique confidential code, ensuring that security and safety are maintained with no problems."
"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."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"This is a unique solution that is very easy to install."
"It is a scalable product."
 

Cons

"Microsoft Intune is not user-friendly to manage and has room for improvement."
"It would be better if they can reduce the cost of the license."
"Once it's configured it is unobtrusive, but it does take some hands-on to configure and deploy it properly."
"Microsoft Intune is currently overpriced."
"Intune could add more features that are relevant to the core application control functions. For example, it would be helpful if it had more control over the on-prem environment from the cloud platform. Greater Teams availability in the Saudi market would also be helpful."
"The tool's tunnel gateway is not very good, making it an area where improvements are required."
"I would like Intune to natively support easier report generation. This improvement would enable less experienced staff to run reports more efficiently without relying on additional tools or functions."
"The worst aspect is the reporting."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"They need to better advertise the features."
"It would be helpful if they had iSupport for supporting Apple phones."
"There could be a section in the menu describing the new features and changes."
"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."
"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."
"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."
"TeamViewer is publicly available and anyone can use it. This is the reason that many organizations do not permit the use of this solution. It is not considered to be secure enough."
"It becomes complicated to switch from one monitor to another for different windows."
"The security could improve in TeamViewer."
"The performance could always be better."
"If were to I put myself in the seat of a small business owner, I would prefer TeamViewer to be more of a pay-once-and-own-it solution, rather than paying via a subscription model (although I am using the free version). Only annual subscriptions are available. It makes paying for it the first time seem a little daunting."
"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 pretty limited on the options they have."
 

Pricing and Cost Advice

"There is a license needed to use the solution and we are on an annual license."
"The price is very reasonable."
"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."
"I am satisfied with the pricing."
"Its price is fair. It's a normal price. It isn't too expensive or too cheap."
"Microsoft Intune costs about $7 per user per month, which is somewhat on the pricier end. That said, it's a reliable product, so it's fair."
"For Microsoft 365 E5 clients, cost is not an issue as this product is one of the benefits."
"Existing E5 license holders for M365, Intune, and Azure, receive a free license."
"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 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 solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"TeamViewer is $600 or $700 per port per year..."
"The solution's pricing is reasonable."
"I used the free version of TeamViewer."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"The version of the solution we are using is free."
