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

"One valuable feature of Microsoft Intune is the enrollment process, which is user-based, making it easier to manage compared to AirWatch."
"The most valuable features are the ones that make sure that the deployment is of a standard operating system and the Zero Touch deployment, which is very useful. This allows users to have an out of box experience."
"We are transforming our flat network by adopting different cloud solutions, and our own applications are hosted in the cloud. Intune ensures our security throughout our entire cloud-based system, improving our security posture."
"The most useful features in Microsoft Intune are the policy enforcement and conditional access."
"Based on my experience, I would recommend Microsoft Intune to organizations looking for management of a large number of devices and enterprise environments."
"I can reach devices or computers over the internet. I don't need to worry about the network connectivity between the offices. I can manage any device. That is the most important part."
"The best features of Microsoft Intune include continuous implementation of new capabilities each year, covering almost everything."
"The most useful features in Microsoft Intune are the policy enforcement and conditional access. These features make our operations easier from a company perspective."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable feature is safety."
"It saves trips to customer sites, which saves time. I am able to get in there remotely and fix things."
"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."
"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."
"This is a unique solution that is very easy to install."
"TeamViewer is a step ahead of solutions like, for example, AnyDesk."
"The most valuable feature of TeamViewer is the ability to remote into another device."
"TeamViewer Business does a lot in the enterprise part and has many features that can be used in big organizations, and it is able to assist on the network side, monitoring, security side, and remote side, making it a good platform and solution to use."
"It is easy to use and has a pretty good UI."
 

Cons

"I want more secure, reliable, and efficient security policies."
"There could be more competent processes and improvements in the policy space."
"I would like more clarity on how Intune is migrating control from Active Directory group policies, especially as we move over to Windows 11. It seems inefficient to manage some settings in Active Directory and others in Intune."
"The solution can have some compliance problems in general and the end-point user can bypass easily the company policies in Intune."
"Intune is not the most user-friendly mobile device management platform available."
"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."
"Reporting and troubleshooting for the application deployment could be better. It's very difficult to understand."
"There are a couple of issues with stability."
"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."
"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."
"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."
"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."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"It becomes complicated to switch from one monitor to another for different windows."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"Support for mobile devices from Linux has been missing since the Native client was rolled out. This was a nice option, especially when trying to walk somebody who was struggling to understand something on their phone."
"I don’t see any areas where improvement is needed."
"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."
"TeamViewer is expensive, and you get a limited number of connections for your money."
"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."
 

Pricing and Cost Advice

"Consider the Microsoft Enterprise Mobility Suite rather than choosing specific sub-components, e.g. only Microsoft Intune."
"We are partners, so we receive some discount. However, from the customer's perspective, Microsoft Intune's pricing is competitive with non-Microsoft technology, and the price is good compared to other market competitors."
"We work with the subscription rather than a server license. I think it's economical this way because we don't have to have a server license for that, and I think that works in our favor."
"Intune is included in the Microsoft 365 licensing package that we have."
"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."
"While Microsoft charges for actual usage, it lacks discount options."
"If you ask the accountant or the finance department, they'll tell you that it is way too expensive, but when I look at the cost and compare it with the value you actually get, it's more than fair."
"There are licenses required for this solution. We enable licenses on the devices we need to manage."
"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 not using the solution for commercial use therefore it is free to use."
"It would be nice if it is cheaper."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"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."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
