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
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 feature I find most valuable in Microsoft Intune is being able to configure policies and push them directly to mobile phones."
"We were trying to solve many issues, mainly the lack of centralized management. Before Microsoft Intune, we had to manually support devices one by one, installing applications and configuring policies individually. When we implemented the tool, it became much easier to manage our devices. We enroll them in Microsoft Intune and can manage all devices with a few clicks. For application management, it's the same process. If we want to deploy applications to hundreds or thousands of devices, we can do it easily with just a few clicks. This also applies to policies."
"The solution is stable."
"As the solution is a software as a service, the scalability is unlimited."
"I would recommend Microsoft Intune to others; it is a very good and scalable solution."
"Microsoft Intune has had a very positive impact on our organization, especially in terms of security and efficiency."
"I appreciate how easy it is to deploy certificates to end users to get control over their device with Microsoft Intune; that's what Microsoft Intune is known for, and that's what we use them for."
"The stability is good."
"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."
"The most valuable feature is safety."
"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."
"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."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"I like that it helped a lot, even with low bandwidth network connectivity; for example, while I was traveling, sometimes there were requirements for me to join a TeamViewer session and provide technical support, and I was able to do that without much of an issue."
"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."
"Quite literally, without TeamViewer's capabilities, we wouldn't be able to run our business."
"The performance and stability are good, there are no bugs or glitches, and it doesn't crash or freeze."
"The quality of the call and the quality of the sharing have been excellent."
"The implementation is quite straightforward."
"Nothing else compares to it at the same level."
"TeamViewer Business has positively impacted my organization because it saves time, as I don't have to go to the customer's place to make some connections or configurations; I can make it remote and very easy."
 

Cons

"The main disadvantage seen today is regarding Linux clients. We have a lot of development resources that have Linux on their clients, and we can't manage them on the same platform, as we do with other clients such as macOS and Windows."
"The solution could improve by having better integration with Apple."
"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 can be delays in the deployment of new policies."
"There should be more focus on mobile device security and integration."
"The solution could be improved by the opportunity to connect third-party application databases, such as Chocolatey or another setup store, to Intune."
"Currently, Microsoft Intune's focus is mainly on Windows, but they can make much more improvement in terms of other platforms."
"Management of Linux devices from Microsoft Intune would be great. Then we can manage any device and not only Windows and Apple."
"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."
"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."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"A feature that they could add is chat with sound to talk."
"The stability of TeamViewer is good, but it could be better."
"TeamViewer could improve by having a cloud version. Having the solution on the system could cause some cyber security concerns with data."
"Full integration of computer's user account system. Be able to login using the local computer's credentials rather than setting up a unique Teamviewer account/password."
"TeamViewer Business's scalability is bad because it's very expensive."
"TeamViewer can improve connectivity. I had some problems connecting to my clients and now I use AnyDesk."
"One thing that would really help with TeamViewer Business is if they were able to provide an easier way to deploy TeamViewer Business on all devices using group policy, as the current solution is quite clunky and very technical to set up; I have struggled and spent many days trying to get TeamViewer Business pushed out via group policy, and it has never worked as we would prefer, so we end up doing it manually, which is a drain on resources."
 

Pricing and Cost Advice

"Existing E5 license holders for M365, Intune, and Azure, receive a free license."
"Intune is included in the Microsoft 365 licensing package that we have."
"The price is very reasonable."
"Intune is cost-effective as it is included in some of the Office 365 packages."
"It's affordable. In comparison to the competitors, the price depends on what features you need from Intune, but it's affordable. There are no hidden costs, but there are some features that go for a premium price. Those are the add-ons for which you have to pay extra."
"It's affordable. It's cheaper if you have an Office 365, E5, or E3 subscription because everything is there."
"It is not expensive."
"The product is offered as part of a Microsoft standard bundle. The pricing can be competitive to Airwatch, and Maas360."
"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."
"It would be nice if it is cheaper."
"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."
"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 are using the free version of TeamViewer."
"TeamViewer has multiple licensing options."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"We're using the free version. We do not pay any licensing fees."
"The cost is in the thousands of dollars per year."
