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

"Our bank's most valuable Intune features are centered around the dedicated device concept."
"Our configuration profiles used to be all over the place. For example, there's a lot of legacy stuff in Active Directory. Going through Intune has helped us enforce settings, which has improved device security and functionality. When you apply something through Intune, you know it works. You don't have to worry about a legacy setting from Active Directory that was uploaded by somebody seven years ago. With Intune, you can see that a device has a setting, and you can be confident that the device is configured how you want."
"Among the most valuable features are the Company Portal that is built into Intune, and the update rings so that we can manage what types of future updates the devices get."
"The one feature we find most useful is the Mobile Application Manager. There are two types, we have the complete MDM and the Mobile Application Manager(MAM). We don't give our users phones, it is their own personal phone, and we need to allow them to have access to the company detail on their phone. We need to create a balance between their own personal data and the company data. We deploy the Mobile Application Manager for them so that we won't be able to interfere with their own personal data."
"I have no issues with the scalability and ability to expand Microsoft Intune."
"It's easy to deploy a configuration or policy to a system, especially when you don't have Azure AD. Now we are talking to all these small and medium-sized customers who don't necessarily have an on-premise Windows Active Directory. If they have invested in Office 365 Premium, this functionality becomes available to them."
"I like Intune's ability to manage roles, maintenance tasks, compliance settings, and patch development for all endpoints."
"The insights, even though we're talking about charts and graphs, are super valuable to customers who might not otherwise know what's in their ecosystem or the current state of things within their ecosystem."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable feature is safety."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"TeamViewer is fast and easy to manipulate."
"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 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."
"The solution is a very good tool for monitoring and for remote access. Anyone is able to use it, it is simple to use."
"I find the mouse control and the ability to click for them very effective. I can move the mouse and click on buttons as if sitting at their computer. These are the basic features I use most often in the solution. There are tricker features that I don't use much because I don't need them frequently. Overall, it's a great tool for helping others with their computer issues without traveling to their location or another building."
"The most valuable feature of TeamViewer is user-friendliness."
"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."
"The product and platform work well. That is why I have stay with them so long. The stability has typically been good."
 

Cons

"I expect Microsoft Intune to have more features in the cloud because there are two major functionalities that we need to be added. This is software metering and license management. These functionalities, for now, must be on-premise. For this purpose, we have set up a SQL Server and I hope that in near future this option will be in the cloud in Microsoft Intune."
"In the past, I raised some tickets for the enhancement feature, which was missing in Intune."
"They should make it easier to order it, however, that's generally true for everything from Microsoft."
"In terms of what can be improved, I am looking for better enhancements regarding Apple management, not only on the mobile device, but also on the laptop."
"Microsoft Intune lacks live location tracking capabilities. Improvements should be made in terms of MDM platforms for other devices."
"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."
"Microsoft Intune lags market leaders, such as Apperian, in its MAM capabilities."
"There are a couple of issues with stability."
"They need to better advertise the features."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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 it if the trial version of TeamViewer allowed you to have a connection for much longer."
"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 has a legacy and may not be using the latest UI trends."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"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 can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"This solution could be improved by offering more flexibility in terms of usage."
"I would like to see TeamViewer support multiple platforms."
 

Pricing and Cost Advice

"Its pricing seems reasonable."
"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."
"It's a bit expensive from a licensing perspective, especially as we look to have organizations with tenants across the globe."
"Microsoft Intune has a user-based subscription model. You can go for a monthly or a yearly payment."
"While I don't have access to high-level financial information, I believe we have achieved lower costs with this implementation."
"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."
"For Microsoft 365 E5 clients, cost is not an issue as this product is one of the benefits."
"Consider the Microsoft Enterprise Mobility Suite rather than choosing specific sub-components, e.g. only Microsoft Intune."
"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."
"The price of the license could be less expensive."
"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 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."
"TeamViewer is $600 or $700 per port per year..."
"The solution's pricing is reasonable."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"The version of the solution we are using is free."
"We're using the free version. We do not pay any licensing fees."
