Featured Reviews

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.

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

"Overall, I like Intune as a solution and would rate it nine out of ten."
"It has helped with compliance. It has helped to ensure that devices comply with the organization's policy. If they are not compliant and secure, they cannot access the resources."
"What I like most about Intune is its seamless enrollment process, particularly the Autopilot method."
"It is very easy for me to configure all the things. Once I create policies and applications in Intune, it is very easy for us to enroll users."
"I like how Microsoft Intune lets me lock down the email profile and make it accessible only on certain devices."
"The ability to push applications on devices is valuable. You do not have to manually install applications one by one. If you like to use ten different applications, you do not have to manually go and download them one by one. Intune can compile a package for you, and then you can just push them from the admin center."
"I like that it's very good and very simple. I found that we just needed to have a proper subscription for an Intune tenant, and from the subscription, if we have the right role assigned, like the global admin role or the owner role, we can use Microsoft cloud resources. With the help of that, we can do many things like setting up Microsoft Intune in the cloud to create our virtual machines. All these can be done, and the steps are very simple. I really liked it. I like features like Windows Auto-Enrollment. I like it very much because whenever you supply it to the end-user, it will be ready to use immediately. The end-user only needs to provide the user credentials, and then they are good to go. I also really like Cloud PC, which was recently launched on Azure."
"The conditional access policies that we set up are very useful."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"We can also monitor our systems at any time from practically anywhere."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The most valuable feature is safety."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"The product is quite stable. The performance is good."
"The solution is scalable."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
"It's a user-friendly product."
"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."
"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."
"It is easy to use and has a pretty good UI."
"The dashboards they have are good."
 

Cons

"There were several bugs with stability."
"Lacking in features such as Wi-Fi and network security."
"When Microsoft Intune is used with different android devices it does not always work as it is supposed to."
"For an existing customer who has an SCCM, it would need to be upgraded to an MECM first before I can introduce Microsoft Intune."
"There is no catalog for mobile access management (MAM) security."
"I would like some integration with the Microsoft reporting platform Power BI."
"Intune has limited integration with non-Microsoft solutions."
"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."
"They need to better advertise the features."
"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."
"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."
"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."
"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."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"Voice communication and screen communication or face-to-face communication could be improved."
"I would like to see something like a TeamViewer mobile application for iOS or possibly Android. I think this would be fantastic given how technology is evolving today. It would be beneficial to use it with your smartphone."
"If you had to teach someone how TeamViewer Business works, especially because I am speaking in a sense that I am using it on an engineer level, it would be a bit difficult to get accustomed to some of the settings, especially with the new experience."
"The file transfer functionality crashes sometimes."
 

Pricing and Cost Advice

"Pricing depends on the features. Microsoft offers special packages if there are more than 10,000 users, and you may be able to get a reduced rate."
"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."
"Intune is inexpensive. It also comes bundled in some Office 365 licenses, so you can choose to purchase it separately or as a package."
"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."
"Intune is included with our F3 and E5 licenses."
"It is reasonable. When you have Microsoft 365 E3 or E5 license, it is already licensed in that license. So, you could say it is free."
"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."
"No one can compete with Microsoft when it comes to price, and the features it is offering."
"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 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."
"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."
"There is a free and paid version of this solution. I am currently using the free version."
"The cost of the licenses depends on how you buy them. They just had a buy one get one free deal going, and they do that every once in a while. Where you buy one license, and they will give you the second one free, or you can try to get discounts. Most of our licenses that we have we tried to do something like that just to save some money."
"We are using the free version of TeamViewer."
"We use the free version of TeamViewer."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
