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

"We have definitely seen a good return on investment with Microsoft Intune, as it saved us a lot of time on manual tasks and reduced the need for extra tools, so overall costs went down as well."
"One of the most valuable aspects of Microsoft Intune is its seamless integration with Azure Active Directory, offering capabilities akin to Group Policy Objects."
"The aspects I find most valuable are managing the data and applications, restricting users from installing any applications, and being able to wipe the data if a phone is misplaced or stolen."
"From my perspective, I appreciate the scalability in Microsoft Intune and the portal management, which is extremely intuitive and very simple to use."
"Microsoft Intune has saved me about 30% of my time through streamlined processes and efficient resource management."
"Overall, I would rate Microsoft Intune as eight out of ten."
"...Intune itself integrates with that entire Microsoft ecosystem. As an individual product itself, it's okay. It holds up. But when you start saying "I've bought this as part of a wider solution, as a company we are going Microsoft throughout," then it makes more sense to have Microsoft Intune... so you have that single dashboard."
"For Windows services, there are multiple options within Intune to modernize it to be more internet-facing and dynamic."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"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."
"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."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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 can also monitor our systems at any time from practically anywhere."
"The product allows easy access to any system in case of any issues."
"The implementation process is simple."
"I would advise others this is the best solution for administrators or IT personnel."
"The solution is stable, reliable, has no bugs or glitches, does not crash or freeze, and the performance is good."
"It's worth every penny; I would recommend it any time."
"Their tech support is really good."
"TeamViewer allows us to do multiple controllers on a Host, which is great. We have a lot of Macs in our organization, and TeamViewer being cross-platform is a good thing."
"The pilot feature is what stands out the most. I love the ability to use the pilot feature for remote inspections. The augmented portion of the software comes in handy when I have to assist my inspectors. They use the app in the field, and they show me what they're seeing through their phones."
 

Cons

"I would say the interface and dashboard summarizing the devices' status and compliance could be improved."
"The security features should be improved."
"An area for improvement is the absence of seamless integration, particularly with external dashboards."
"I would like Intune to natively support easier report generation. This improvement would enable less experienced staff to run reports more efficiently without relying on additional tools or functions."
"There are areas that have room for improvement in Microsoft Intune, particularly regarding integrations."
"Microsoft needs to enhance device-level security, as sometimes when using Microsoft Intune, the device's operating system becomes stuck and requires a full uninstall to remove the Intune bug."
"The interface is not as modern as some competitors in terms of single pane of glass visibility across the entire landscape. It has a very Azure vibe and may not be as graphically appealing as other products."
"While the ability to deploy applications at startup is reliable, the policy-based application deployment method has not reached the same level of consistency."
"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."
"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."
"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."
"We miss the possibility to communicate via head-set in ISL."
"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."
"There could be a section in the menu describing the new features and changes."
"A feature that they could add is chat with sound to talk."
"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."
"Sometimes we'll have a device in the field, and I'll click on remote control and it says "Can't authenticate." I'll double click in a different part of the TeamViewer interface and it'll say "Can't authenticate." Then I'll do it a third time and it connects."
"TeamViewer Business's scalability is bad because it's very expensive."
"The price is a killer for the amount I normally use it."
"They really need an AMT client and/or iLO client for business use."
"Voice communication and screen communication or face-to-face communication could be improved."
"Sometimes we'll have a device in the field, and I'll click on remote control and it says "Can't authenticate." I'll double click in a different part of the TeamViewer interface and it'll say "Can't authenticate." Then I'll do it a third time and it connects. It's possible that it's just bad luck. It's also very possible that it's some bug within TeamViewer..."
 

Pricing and Cost Advice

"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."
"The overall pricing of Microsoft Intune is good for companies that have big IT budgets, 3,000 or more users and devices."
"Pricing can be improved."
"The price of Intune is included with the license for Office 365, so we don't have to pay anything extra for it."
"The tool is cheaper than our company's other MDM tools."
"It's a part of Microsoft 365 and E5 licenses. Microsoft's strategy of making every feature in Microsoft Intune paid needs optimization. Remote control is one of the basic features, not a luxury feature, yet we must pay for it. I"
"I would rate the price a four out of ten with ten being the most expensive."
"It is average. Some of the costs are quite high depending on what the customer currently uses, but overall, it is not bad. I would not say that I would not recommend Intune based on the cost. I definitely would, but they can definitely improve on the cost. So overall, its cost is not bad."
"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."
"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."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"The price was cheaper than what we were previously paying. At the time that we went with TeamViewer, we were using ShareConnect. The TeamViewer package was about half the cost and able to have a bigger number of users."
"The version of the solution we are using is free."
"We're using the free version. We do not pay any licensing fees."
"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 permanent license and the price is reasonable."
"The cost is in the thousands of dollars per year."
