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

"By using Microsoft Intune, I can control my Outlook on my phone, and whenever I try to open any file attachment, it will be more secure."
"The solution is easy to use."
"I like how Microsoft Intune lets me lock down the email profile and make it accessible only on certain devices."
"I really appreciate the features in Microsoft Intune, including the Intune Suite Cloud PKI."
"It's easy to deploy a configuration or policy to a system, especially when you don't have Azure AD. Now we are talking to all these small and medium-sized customers who don't necessarily have an on-premise Windows Active Directory. If they have invested in Office 365 Premium, this functionality becomes available to them."
"Its protection policies are most valuable, it protects mobile devices as well as individual apps, it is pretty scalable, and its documentation is also pretty good."
"The Mobile Device Management in Intune is a valuable feature."
"Intune is effective because of the configuration management and endpoint security it provides. The graphical interface makes it easier to configure and deploy devices."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"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."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"ISL is a fundamental partner for us since, throughout all these years, it has allowed us to grow and solve the problems of our customers and their users in a very fast and agile way without having to move, even providing service abroad."
"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."
"We've been very happy with the solution over a number of years."
"TeamViewer is fast and easy to manipulate."
"This is a unique solution that is very easy to install."
"Their tech support is really good."
"This solution is straightforward to use."
"The solution is very stable, and we've never had a problem with it."
"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."
 

Cons

"I wish Microsoft would keep up with their documentation. They make changes so quickly to these platforms that they do not update the documentation properly in a timely manner."
"Some customers have reported experiencing slowness when using lower versions of the Android system."
"I think that there is room for improvement with the reporting. If this is done, it will be a better product."
"I would say the interface and dashboard summarizing the devices' status and compliance could be improved."
"It would be better if Microsoft can reduce the cost of the license, as we know the Intune device subscription is licensed per device at a cost of $2 a month, but for the best enhanced security and features we must add an add-on license or buy or upgrade to a bundling license such as M365E5."
"Manually syncing devices to enforce policies is cumbersome."
"Intune's reporting and logging could be improved. When troubleshooting, it's difficult to collect the logs and determine what's happening. If I want to filter out the compliant devices, I can see it from the logs, but I would like the option to drill down further."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"It would be helpful if they had iSupport for supporting Apple phones."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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 easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"Oftentimes, the session window blocks view of the system tray. I’d like to be able to minimize it or move it."
"The solution could improve by increasing or removing the time limitation on the use of a session."
"The support could improve their speed."
"The product could be less expensive."
"I'm not sure if they provide good quality audio alongside screensharing."
"They could give more information about using certain kinds of applications for secure transactions, such as secure file transfers."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"In the past, use in wireless environments caused buffering due to limited bandwidth."
 

Pricing and Cost Advice

"Microsoft Intune is pretty reasonable. We have difficulty with Azure, which is probably why we have not put many assets in Azure. Everything we put there is very expensive."
"The cost is somewhat on the higher side, particularly when considering certain price points, especially in markets like India."
"While Microsoft charges for actual usage, it lacks discount options."
"Microsoft's licensing is more flexible and adaptive than its competitors."
"I have no comment on pricing of the solution."
"Our Office 365 Business Premium license, including Office 365 and Intune Management, offers excellent value."
"I liked the tool's pricing until P2 came into effect. I am unsure about the current value versus the cost of the new licensing model."
"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."
"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 will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"TeamViewer has multiple licensing options."
"The cost is in the thousands of dollars per year."
"The pricing is a little bit on the higher side."
"The version of the solution we are using is free."
"The solution's pricing is reasonable."
"TeamViewer was willing to give us a one-year package. Whereas, a lot of the other companies that we explored were paid by the month or quarter. It's just easier for our finance people at the college if we can make a one-time yearly payment."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
