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

"As the solution is a software as a service, the scalability is unlimited."
"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."
"It is very easy for me to configure all the things. Once I create policies and applications in Intune, it is very easy for us to enroll users."
"The security compliance capabilities make it widely adopted across organizations."
"A great solution for anyone wanting a modern endpoint device management solution."
"What I like most about the tool is that it's now very easy to set up a device for someone to use. It also helps us tremendously in managing security. Before, we used on-premise management with a domain controller. It was difficult to manage security comprehensively. For example, it was hard to know which computers were updated. We weren't able to do that easily with our previous solution."
"The most valuable feature for us is the security, including risk analysis and patch management."
"I haven't used other mobile device management solutions, but compared to SCCM, we eliminate a lot of on-premises infrastructure and maintenance by using Intune."
"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."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"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."
"The product and platform work well. That is why I have stay with them so long. The stability has typically been good."
"The quality of the call and the quality of the sharing have been excellent."
"TeamViewer Business has positively impacted my organization because it saves time, as I don't have to go to the customer's place to make some connections or configurations; I can make it remote and very easy."
"Ease of use was the number-one thing. It's an industry leader for ease of use, specifically on the client-side, which is the absolutely critical thing. If I want to connect to somebody, how easily can I — without seeing their computer — walk them through the steps to install it to a point where I can key in the code and help them resolve their situation?... TeamViewer is just a dead-solid, easy answer."
"The solution is very stable. We've never had a problem with it."
"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."
"It is a scalable product."
"TeamViewer has a lot of options for deploying the Hosts, where you can mass deploy them very easily, and you can pre-configure them."
 

Cons

"One thing I would suggest is that servers are not getting managed through Microsoft Intune."
"Certificate management within Microsoft Intune's Suite is still under development. It's not very reliable compared to other certificate tools, though it has made good progress within a couple of years."
"Intune's privilege management feature, while beneficial, is less intuitive than other Intune features, making it challenging to use."
"Manually syncing devices to enforce policies is cumbersome."
"The granular support for other device types in Microsoft Intune could be improved."
"The installation is very easy. However, to be able to configure it you will need special knowledge, such as training or self-studies to have a proper level of security. There are many settings one has to understand before being able to implement Microsoft Intune."
"Intune's server management could be better. If it could incorporate more features from System Center into Intune's Configuration Manager, it would be beneficial."
"Integrating certain group policies can be challenging and may necessitate using on-premises systems to integrate them with Microsoft Intune."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"They need to better advertise the features."
"There could be a section in the menu describing the new features and changes."
"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."
"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."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"I would like to be able to access and manage all brands of smartphones."
"I would like it if the trial version of TeamViewer allowed you to have a connection for much longer."
"TeamViewer has a legacy and may not be using the latest UI trends."
"A feature that they could add is chat with sound to talk."
"They should release features such as Augmented Reality into both plain and standard versions of TeamViewer."
"Sometimes it gives problems, with the button not working, and I was unable to log in."
"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."
"One possible feature would be to have multiple sessions open, as in, if someone has two or three monitors, then you can have two windows show up per monitor instead of having to switch one screen."
"TeamViewer can improve by making the interface more user-friendly. It looks very basic, they can make it more modern and easy to use."
 

Pricing and Cost Advice

"Intune is linked with Microsoft. We can deploy the Microsoft E365 license to users by Intune. There are different types of licenses, such as device administrator licenses, E5 licenses for device enrollment manually, and P1 and p2 licenses for device enrollment automatically. These are the licenses required for the administration."
"The overall pricing of Microsoft Intune is good for companies that have big IT budgets, 3,000 or more users and devices."
"The cost of the license and the features are justified for myself as a technical person."
"The price for Intune is fair."
"I rate Intune an eight out of ten for affordability. It's bundled with the 365 licensing, which is competitive overall."
"This cost is approximately $30 USD per user per month."
"Pricing depends on the features. Microsoft offers special packages if there are more than 10,000 users, and you may be able to get a reduced rate."
"I recently got to know that the AD P1 license is compulsory to use Intune Autopilot, which was surprising for me. Earlier, this was not the case. It is the wrong thing to do. We now need to purchase AD P1 licenses for us and for our customers. I would rate it a seven out of ten for 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."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"We have a corporate license. The maximum amount number of users changes based on the amount you pay. E.g., with our license, there is a maximum amount of users who can use the solution at the same time (10 users)."
"It would be nice if it is cheaper."
"We use the free version of TeamViewer."
"There is no license needed to use TeamViewer."
"We are not using the solution for commercial use therefore it is free to use."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"It does what I need it to do but I think it's expensive. It wasn't easy for me to get approval from the company to get it... It's costing us about $700 a year, per license."
