Centralized device management has transformed security and streamlined remote provisioning
One area where Microsoft Intune can improve is the user interface. Sometimes the portal feels a bit complex and not very intuitive, especially for new users, and it can take time to find specific settings. Another point is troubleshooting. While logs are available, the diagnostic policies and sync issues can still be time-consuming and not very straightforward. I also feel that reporting could be more detailed and customizable. The built-in reports are helpful, but for deeper insights, I often need to rely on additional tools. Overall, it is a strong solution, but improving usability and troubleshooting experience would make it even better. While Microsoft Intune works very well within the Microsoft ecosystem, the integration of some third-party tools could be smoother and require less customization. Support is another area that could improve, as sometimes response times can be slow, and resolving complex issues may take longer than expected. In terms of features, I think more advanced automation and built-in remediation options would be helpful since common issues can be fixed automatically without manual intervention.

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

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

"When comparing Microsoft Intune to Jamf, Microsoft Intune is superior."
"The many policies available in Microsoft Intune for managing our devices are valuable."
"The best feature is that we don't need to worry about downtime. We don't need to worry about the network connections of our office or the virtual private network. Everything is being done through the internet. Using Intune Autopilot, we can configure and deploy everything to the devices."
"I would say that it is at the top of the list when it comes to the competition."
"Fortunately, now everything is streamlined into a single, unified platform."
"Microsoft Intune saves eight hours per day, and during my work hours, I use my time to study and run tests on configurations I'm curious about and try them out in my environment."
"Implementing Microsoft Intune has provided a more streamlined and consistent method for device management across our multiple domains, effectively consolidating our administrative efforts."
"It's not working perfectly, but Microsoft's Autopilot offers great visibility into automated deployment solutions."
"Setting up the solution is easy and there's no maintenance involved."
"The stability is great; reliability is what's very important to me, as well as security, and this solution may have only had one instance of downtime in 14 years."
"Without ISL Online, I would not be able to work from home."
"We are just much more responsive, we can be faster, and we can support our customers in a better way because when they have a problem, we can be on their computer immediately."
"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."
"Good communication is a key to good business and ISL helps a lot."
"The most valuable feature is safety."
"Before TeamViewer, our remote personnel had to rely on taped video training, but now they get one-on-one training as I walk them through things on their computers."
"I use TeamViewer to connect to other workstations, Mac, or PC without a VPN connection."
"The product is really straightforward and completely easy to implement."
"The pilot feature is what stands out the most; I love the ability to use the pilot feature for remote inspections, and the augmented portion of the software comes in handy when I have to assist my inspectors as they use the app in the field and show me what they're seeing through their phones."
"The most valuable feature of TeamViewer Tensor is the remote access."
"With an image, you can see immediately what's going on. You can run some tests. Without the solution, you need to do everything by telephone. It's not even thinkable."
"The most valuable feature of TeamViewer is user-friendliness."
"From my perspective, the most important is the login."
 

Cons

"The security aspect could be more effective."
"Historically, Group Policy has simplified the management of various items, such as printer and drive mappings and while Intune offers workarounds, it lacks native support for these functionalities. This is an area I believe needs improvement."
"Microsoft Intune's support for Mac devices is lacking and could be improved."
"Regarding mobile devices, Intune is good, but there are other services that I would say are ahead of Intune from an administration and reporting point of view."
"Could benefit from user having more control over devices."
"Microsoft Intune could improve by being more user-friendly and having it geared toward device management. The graphic interface is not very good."
"There is room for improvement in integrating additional features such as Purview and SharePoint activities into Intune."
"What I'd like to see in their next upgrade is more in the context of today's security policies and what's needed, for them to keep adding features based on that, for example boosting security, so they can keep on adding security features, and that is the best they can do."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"What bothered me the most was that when I connected to the computer at the office, I was afraid that someone would turn on the monitor and watch what I was doing."
"They need to better advertise the features."
"There could be a section in the menu describing the new features and changes."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"It would be helpful if they had iSupport for supporting Apple phones."
"I would like to be able to access and manage all brands of smartphones."
"We miss the possibility to communicate via head-set in ISL."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"When clients have a newer version installed and we only have a license for version 8, there are issues."
"The product can sometimes crash."
"I believe the graphical resolutions can be improved on the product, as apart from this, the product is very easy to use and easy on the eye."
"The business interface is clunky and not well-documented."
"Sometimes it gives problems, with the button not working, and I was unable to log in."
"TeamViewer Business could be improved with a very basic transfer interface for files and folders transfer with an indication of the size of the transferred files and estimated time needed."
"It does what I need it to do but I think it's expensive."
 

Pricing and Cost Advice

"The clients pay for a license and each can have a different type of license, such as an E3 or E5."
"I am satisfied with the pricing."
"Microsoft Intune is expensive."
"Intune is linked with Microsoft. We can deploy the Microsoft E365 license to users by Intune. There are different types of licenses, such as device administrator licenses, E5 licenses for device enrollment manually, and P1 and p2 licenses for device enrollment automatically. These are the licenses required for the administration."
"It's monthly for us, but it's built into the license cost that we pay our IT each month. It's maybe 129 Kroner per head, which translates to £10. There are some additional costs. Our IT had to set up and configure their own server, so there is an extra cost for that, but I'm not sure what that costs."
"As a partner, we always look for how we can generate more revenue from a consulting point of view, but I do not see any complaints from the customer side regarding pricing, so they are satisfied with it."
"Even if they charge a premium, they aim to provide equal value."
"I don't have any problem as far as cost is concerned. It is bundled with our license."
"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 is $600 or $700 per port per year..."
"We have a permanent license and the price is reasonable."
"We are not using the solution for commercial use therefore it is free to use."
"We are using the standard free version of TeamViewer."
"I rate pricing a ten on a scale from one to ten, where one is low and ten is high. There are no additional costs attached to the licensing of the solution."
"We have an annual subscription that is just under $1,900 with no additional costs. We get these promotions about upgrades and stuff like that, but we haven't had a need to add more seats. Users can also use TeamViewer for home use with a non-commercial free license."
"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)."
"We're using the free version. We do not pay any licensing fees."
