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.
Begaya Morris - PeerSpot reviewer
Lead Software Engineer at BD
Reliable remote access has improved secure collaboration and streamlined daily approvals
The best features TeamViewer Business offers in my opinion are collaboration, templates, a high level of security, and session recording. Collaboration allows me to collaborate remotely with my team members. Besides reconnecting automatically, it provides a high level of security, protecting from cyber attacks and aids in providing assurance in regulated environments through two-factor authentication and end-to-end encryption features. It also allows recording live sessions, which can be replayed as needed for future reference. TeamViewer Business has positively impacted my organization as collaboration has enhanced, especially remote collaboration by 60 to 70 percent. I have been able to collaborate with clients and other team members seamlessly. Enhanced workflow efficiency includes faster approvals and a lowered risk of data loss, misuse, and leak through robust features like two-factor authentication and end-to-end encryption. It also facilitates compliance using documentation and auditing through recordings and logs.

Quotes from Members

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

Pros

"The features of Microsoft Intune that I appreciate the most are its user-friendly interface and robust security options."
"The best features include the management, which is quite good, and endpoints."
"The ease of applying security policies to applications we deploy is the most valuable feature of Microsoft Intune."
"I would rate Microsoft Intune a nine out of ten."
"I particularly appreciate the administration and security features, which can be deployed easily."
"I mainly use Microsoft Intune analytics for taking that data that exists and bringing it into Power BI dashboards to make it visible to our clients, showing them all the operating systems in their environment and where the latest patches are, and then from there creating plans."
"Intune can wipe devices. For example, if a disgruntled employee wants to leak the data on their company phone, Intune can terminate their access and wipe the entire device with a click."
"The most valuable feature is the policy CSPs."
"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."
"We can also monitor our systems at any time from practically anywhere."
"The most valuable feature is safety."
"Setting up the solution is easy and there's no maintenance involved."
"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."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The product is easy to install."
"It's pretty easy to use. Just key in an ID and password and connect. For meetings, just enter the meeting ID and connect."
"The most valuable feature of TeamViewer is its ease of use."
"The solution is scalable."
"The most important feature of TeamViewer is its ease of use."
"It was worth the investment. You can do file transfers and video calls with it. You can do a lot of copy paste stuff. E.g., if I have a file and want to place it on somebody's machine, I can just copy it off of mine and paste it right on their machine. I don't have to put it in a Dropbox account and have them log into it to pull it off. I can do all that right through TeamViewer. When you're looking at the TeamViewer screen, you think you are working on your own machine."
"Getting started with TeamViewer was easy, with a very straightforward usage"
"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."
 

Cons

"The product needs to upgrade itself when the server is overloaded."
"I am not involved in the day-to-day with Intune, but we have gone with a different product for updating mobile device software. We do not integrate many of our mobile devices that are not Microsoft-based devices, such as Dell laptops, with Intune."
"The interface is easy, but it is not user-friendly when evaluating the overall user experience of Microsoft Intune."
"The security aspect could be more effective. We are using other applications to manage network devices and groups, so if Microsoft Intune could improve in this area, especially on a network level, it would be a real advantage."
"While the ability to deploy applications at startup is reliable, the policy-based application deployment method has not reached the same level of consistency."
"Microsoft Intune lacks live location tracking capabilities."
"We only have major classifications for iOS and Android, but there are different brands that have different cycles of updates. If they can fine-tune it to make it more brand-specific, that would be even better."
"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."
"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 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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"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."
"They need to better advertise the features."
"The performance could always be better."
"It's not the program itself that's an issue, but there is a need for some better documentation on how to use the web portal Management Console. That seems to be a bit lacking in directions, if you aren't paying attention and you don't know what to do. Better documentation would make it a little bit easier to set things up in different groups and share groups between people."
"In the next release, I would prefer to have a voice integration and collaboration feature to support multiple teams simultaneously."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"One thing I have noticed is that TeamViewer does not work so well when the machine you are trying to connect to remotely is not running the same version as your machine."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"The support could improve their speed."
 

Pricing and Cost Advice

"Its price is in the medium range. It is acceptable because you're paying for the features. I am not aware of any additional costs."
"We don't get Intune as a separate module. Most of the time, we use it within an enterprise agreement like E3 or E5. Those licenses are at a good price, but what is annoying is that every single year they go higher."
"The price could be better."
"The cost is handled through our Office 365 license, so I have yet to be able to compare it directly with other tools in its class."
"Microsoft Intune is available for individual purchase at a low per-device cost."
"Intune is included with our F3 and E5 licenses."
"We use Defender ATP and E5 licenses."
"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."
"The solution's pricing is reasonable."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"TeamViewer has multiple licensing options."
"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."
"The cost is in the thousands of dollars per year."
"We're using the free version. We do not pay any licensing fees."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"The version of the solution we are using is free."
