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

"The security features are most definitely valuable. If I have to give an example, the lockdown features that prevent employees from configuring anything or downloading company data are valuable. We get high-quality device protection, malware protection, and information protection at the same time."
"The mobile application management, MAM, is the most useful aspect of the solution."
"Intune's most valuable features are the device, compliance, and configuration policies."
"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."
"It has improve our organization through the remote management of non-domain joined devices."
"Comparing this to having an endpoint management solution, the efficiency gain may be up to 80%."
"Microsoft Intune is best for Windows devices and security in Office 365 and Microsoft-related enterprise environments. It's a nice platform for endpoint management."
"Technical support, in general, has been quite helpful."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"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."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"Setting up the solution is easy and there's no maintenance involved."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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 solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"The most valuable feature is safety."
"It's very easy to set up."
"I am satisfied with TeamViewer, and its performance."
"The most valuable feature of TeamViewer is its ease of use and beneficial remote access."
"The most valuable feature of TeamViewer is user-friendliness."
"Saving users in the interface has helped our workflow and made things easier for our team because we use it every single day, and we would struggle to support our teams effectively without TeamViewer Business; it has made things much easier."
"It's pretty easy to use. Just key in an ID and password and connect. For meetings, just enter the meeting ID and connect."
"TeamViewer Business has positively impacted my organization by giving us the ability to provide clients with a good experience and to fix bugs quickly while accessing their computers."
"I have been satisfied with TeamViewer overall."
 

Cons

"There should be more predictability in the release cycle. We don't feel we have any control over when new updates come out, and whether there are changes to the backend functionality or to the user interface. Updates just happen."
"The policies we had in SCCM and AD offered features that are missing from Microsoft Intune."
"It would be helpful if there was proactive remediation."
"Intune should improve its software inventory to provide better metering of which software is used throughout the company. This is especially needed for reporting third-party software solutions."
"For additional functionality, I suggest that Microsoft could expand on asset management. Since the platform is there, they could develop it into a full-fledged asset management system."
"Enhancements for managing MacOS more comprehensively would be beneficial."
"The reports that are generated aren't so great. They don't give a lot of meaning so far, but that could be down to user knowledge than the actual reporting side of things. I'm not a big user of it, but I was a bigger user of MaaS360, and we used to be able to run weekly and monthly reports. In the case of any deviations. we'd get a warning immediately. That's not so easy to do or to get in place for Intune. This could be just a user issue, but when I compare both, that's the only thing that's lacking for me."
"I think that there is room for improvement with the reporting. If this is done, it will be a better product."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"There could be a section in the menu describing the new features and changes."
"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."
"I would like to be able to access and manage all brands of smartphones."
"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."
"TeamViewer can improve by making the interface more user-friendly. It looks very basic, they can make it more modern and easy to use."
"The product's expensive nature is an area of concern where improvements are required."
"It would be beneficial to have group functionalities to separate access when many consultants want to access different departments or clients at the same time."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"The file transfer functionality crashes sometimes."
"TeamViewer is publicly available and anyone can use it. This is the reason that many organizations do not permit the use of this solution. It is not considered to be secure enough."
"I'm not sure if they provide good quality audio alongside screensharing."
 

Pricing and Cost Advice

"I rate Intune an eight out of ten for affordability. It's bundled with the 365 licensing, which is competitive overall."
"I rate Intune five out of 10 for pricing. It's expensive."
"In terms of the product price and licensing costs, my company finds the product to be reasonably priced."
"The cost of the license and the features are justified for myself as a technical person."
"Microsoft licenses are costly."
"With one user base license, we can use Intune for up to five devices. However, with Soti MobiControl, each license is tied to a single device, meaning one license is dedicated to one device only."
"My team members bundled it together with their Microsoft solutions, including Microsoft 365 and related products."
"Intune is moderately expensive. You can get the license bundled with Office 365 E3 or E5 licenses. The E5s are a bit expensive, but you get some cheaper solutions with 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."
"We are not using the solution for commercial use therefore it is free to use."
"There is a free and paid version of this solution. I am currently using the free version."
"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."
"I used the free version of TeamViewer."
"TeamViewer offers a free version to try. Download and give it a shot. See what it's like and if you like it, then buy the license for it."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"We have a permanent license and the price is reasonable."
