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 improved productivity and saves onsite visits through fast issue resolution
TeamViewer Business provides a fast and secure connection along with a reliable chat feature for a smooth support section. I also appreciate the monitoring and asset management capability, which enhances the remote access experience for my team and me. TeamViewer Business provides seamless communication capability, which includes a variety of options such as chat, call, and video that enhance interaction with our remote clients. TeamViewer Business has been really helpful in my organization, where we are able to troubleshoot any issue our clients have and resolve it as quickly as possible. It enables me to fix the problem faster. If a customer's screen is not working or a glitch happens, I can simply share their screen into my screen through TeamViewer Business and rectify the issue rather than asking them to describe the problem via email. This saves a lot of time and is helpful for our customers who are buying our products. The best features TeamViewer Business offers include seamless communication, efficient remote access, and fast and secure connection.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The Advanced Endpoint Analytics in Microsoft Intune has improved and helps us proactively detect and remediate anomalies in endpoints."
"While I don't think you can ever have full visibility and control, Intune certainly allows us to see the applications being used and tells us if things like Windows patches aren't applied to machines. It does a good job. That visibility makes life a little easier."
"The initial setup is not overly complex or difficult."
"Intune provides full visibility into all active mobile device users. If their devices are noncompliant with our security policies, I have the flexibility to update them remotely."
"I like Intune's ability to install software to a device remotely and push policy through the Azure portal."
"Microsoft Endpoint Manager is not expensive overall, especially for small environments."
"The most important thing for me is the autopilot feature."
"Microsoft Tech Support is good, providing solid support."
"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 can also monitor our systems at any time from practically anywhere."
"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."
"The most valuable feature is safety."
"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"TeamViewer has a good interface."
"TeamViewer allows us to do multiple controllers on a Host, which is great. We have a lot of Macs in our organization, and TeamViewer being cross-platform is a good thing."
"There have been a couple of times with the handy remote access feature, where I have been asked for something at eight o'clock on a Thursday evening and it is on my desk machine, but I am driving back to my office. With TeamViewer, I can just stay at my home machine, connect to my work machine, and get the data needed without having to drive back across town."
"The most valuable feature of TeamViewer is the remote access connection. Additionally, it is easy to use."
"The most valuable features of TeamViewer are the ease of connecting to remote computers. I do not need a lot of information about their computers to connect, a nontechnical person can give me the information needed for me to connect. Additionally, the solution does not gather other system information about the host or client's systems as other solutions might, such as AnyDesk."
"The most valuable feature of the solution is that it is very fast. The file transfer from remote machines to my machine or from my machine to the remote machine works well."
"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."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
 

Cons

"It would be awesome if Microsoft opened their API so we could filter more properties. If we have to do anything outside of Intune that requires a third-party solution to talk back to it, we're very limited in what we can do. Trust your people. We promise not to break your stuff. Open it up just a tiny bit wider."
"When we implemented Intune, it would have been helpful if Microsoft had provided some videos or data about Intune."
"Some enrollment features could be improved."
"Microsoft needs to enhance device-level security, as sometimes when using Microsoft Intune, the device's operating system becomes stuck and requires a full uninstall to remove the Intune bug."
"The technical support could be improved."
"My main pain point for Microsoft Intune is the contact part. Not all Android or iOS applications have access to integration, for example, contacts."
"I think there should be a better tracking of the cell phones used on the Intune."
"We face multiple scenarios where IT decision-makers request specific policy implementations, however, due to product limitations, we cannot fulfill these requests."
"It would be helpful if they had iSupport for supporting Apple phones."
"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."
"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 be able to access and manage all brands of smartphones."
"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."
"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"TeamViewer Business can improve in terms of price and the complexity of licensing, which is a drawback, especially for smaller teams or casual users due to frequent license changes and forced upgrades."
"I would like it if the trial version of TeamViewer allowed you to have a connection for much longer."
"The product's expensive nature is an area of concern where improvements are required."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"TeamViewer can improve connectivity. I had some problems connecting to my clients and now I use AnyDesk."
"It's pretty limited on the options they have."
 

Pricing and Cost Advice

"Microsoft Intune's costliness stems from licensing fees and the overhead associated with its management, user experience, and device remediation."
"Intune is available as an individual product, but it also comes with Office 365 Premium or an Enterprise license, and the price varies for each version."
"Consider the Microsoft Enterprise Mobility Suite rather than choosing specific sub-components, e.g. only Microsoft Intune."
"Intune's pricing is reasonable considering its benefits and the high costs it helps avoid."
"Intune is included in the Microsoft 365 licensing package that we have."
"It's monthly for us, but it's built into the license cost that we pay our IT each month. It's maybe 129 Kroner per head, which translates to £10. There are some additional costs. Our IT had to set up and configure their own server, so there is an extra cost for that, but I'm not sure what that costs."
"I liked the tool's pricing until P2 came into effect. I am unsure about the current value versus the cost of the new licensing model."
"Cost is not my department, but the product is included in the E5 license that we already pay for every user, so no additional cost is incurred."
"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 is $600 or $700 per port per year..."
"TeamViewer pricing is reasonable... The simultaneous controller licensing model of TeamViewer - compared to LogMeIn’s controlled Host licensing model - seems to benefit us so far. We’re currently saving about 30 percent on licensing cost... The savings from licensing have been eaten up by the soft costs involved in dealing with and working around TeamViewer’s deficiencies in allowing granular control by multiple controllers, and the issues with the various settings that are missing on the macOS Host."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"The solution's pricing is reasonable."
"We use the free version of TeamViewer."
"We're using the free version. We do not pay any licensing fees."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"It would be nice if it is cheaper."
