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

"If I assess Intune's user experience, I would say it is perfect and simple."
"Intune has significantly benefited our organization by providing comprehensive visibility into our device ecosystem."
"The most valuable feature is the policy CSPs."
"It's easy to manage and easy to configure."
"The most valuable features of Microsoft Intune include remote updates. The update runs in the background, so there's no need in most cases to go on-site to do it."
"If any user tries to access company data, it directly interacts with the conditional access policy. This helps us protect our data and set the criteria for how data can be accessed and shared."
"We work completely in a Microsoft environment. Its interface is similar to other Microsoft solutions that we are using such as Microsoft Defender. So far, for our administrators, it is easy to use."
"For the price, the features included with Microsoft are appealing."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"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."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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 most valuable feature is safety."
"I recommend it as a solution for remote disk users."
"I am satisfied with TeamViewer, and its performance."
"Using TeamViewer for my personal clients has made things much better for me and my clients because my clients are happy to resolve a problem within seconds via TeamViewer."
"TeamViewer has a lot of options for deploying the Hosts, where you can mass deploy them very easily, and you can pre-configure them."
"The most valuable features of I use TeamViewer are the ease of access and frequent updates."
"The document control is quite good."
"The most valuable feature of TeamViewer is the ability to remote into another device."
"This is a unique solution that is very easy to install."
 

Cons

"Intune should improve the management of non-Microsoft devices. It would be better to manage Mac, Android, and other non-Microsoft operating system devices within the same Intune interface."
"The main disadvantage seen today is regarding Linux clients. We have a lot of development resources that have Linux on their clients, and we can't manage them on the same platform, as we do with other clients such as macOS and Windows. So, it should have support for Linux clients. It should also have better support for macOS."
"Onboarding of endpoint devices is not straightforward. The onboarding process was a little heavier than I thought it would be. That's the key improvement area. Obviously, the more control you have over the devices, the better it is."
"The solution requires Mac support."
"I assess the stability of the product as low. I have faced downtime crashes and performance issues with Microsoft Intune."
"Once it's configured it is unobtrusive, but it does take some hands-on to configure and deploy it properly."
"Regarding mobile devices, Intune is good, but there are other services that I would say are ahead of Intune from an administration and reporting point of view."
"There are a lot of updates happening on Microsoft."
"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 should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"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."
"There could be a section in the menu describing the new features and changes."
"I would like to be able to access and manage all brands of smartphones."
"Sometimes it lags."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"It becomes complicated to switch from one monitor to another for different windows."
"It's pretty limited on the options they have."
"TeamViewer can improve connectivity. I had some problems connecting to my clients and now I use AnyDesk."
"TeamViewer is expensive, and you get a limited number of connections for your money."
"In the next release, I would prefer to have a voice integration and collaboration feature to support multiple teams simultaneously."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
 

Pricing and Cost Advice

"We don't pay for Intune because it is bundled with the premium subscription to Office 365. It includes Intune and Defender. I don't have to buy two extra products to manage my enterprise."
"This cost is approximately $30 USD per user per month."
"The pricing is competitive, but it is not cheap."
"Intune's pricing is competitive. For example, the license of Blackberry's Enterprise Mobility Suite was costly, but Intune is affordable. It is included as an additional feature when you buy security enhancements for your organization. For example, let's say I have fifty users in my organization and all of them are using Microsoft cloud services, like Teams, Office 365, and OneDrive."
"Its licensing model is not complex, but it is very expensive compared to other solutions. They can bring more models and reduce the pricing. They should allow customers to select the features they want and price it accordingly."
"We use Defender ATP and E5 licenses."
"The product is relatively pricey, but considering its benefits, I'd say it's fair. The benefits outweigh the expensive licensing fees, especially for large organizations, but medium-sized and smaller businesses may be unable to afford it."
"Any bundle package, such as Security E3, covers multiple things, such as AAP, BitLocker, etc. If you go for them individually, they would be more expensive. Bundling makes the price more attractive and competitive."
"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."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"The cost is in the thousands of dollars per year."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"The version of the solution we are using is free."
"There is a free and paid version of this solution. I am currently using the free version."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"We are not using the solution for commercial use therefore it is free to use."
