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

"...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."
"Endpoint Manager has been around the longest, it's survived, it's matured and it's the top dog in general."
"The interface is user-friendly, and the reporting tool works in real-time."
"There are so many features, but Windows Autopilot is one of the features that are very valuable for most customers."
"It is a helpful tool to manage BYOD policies."
"The most useful features in Microsoft Intune are the policy enforcement and conditional access. These features make our operations easier from a company perspective."
"I like the tool's integration with Apple. Anyone who creates an ID in Intune will get an Apple ID."
"Intune is flexible. If you want to move a device that was previously on-prem, we can bring it to the cloud and apply all the policies. This is helpful for even those organizations that were on-prem and not on the cloud. They can also come and use these features, which are pretty cool and would be handy to protect the data and manage the devices as well."
"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."
"ISL Online is easy to use and it provides a single platform for various challenges we face in IT."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The most valuable feature is safety."
"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."
"TeamViewer has positively impacted my organization by improving the way our team communicates and enhancing our efficiency."
"The most valuable features of TeamViewer are the ease of connecting to remote computers. I do not need a lot of information about their computers to connect, a nontechnical person can give me the information needed for me to connect. Additionally, the solution does not gather other system information about the host or client's systems as other solutions might, such as AnyDesk."
"There is a relevant return on investment, especially when my previous organizations assisted with remote access features, as rather than needing to go on-site, we could connect remotely, making it easier for those who are not tech-savvy, thanks to TeamViewer Business's user-friendly features, which helped immensely, especially when assisting elderly clients, and ensured we met metrics effectively, creating a significant positive impact."
"The usability and graphic interface stand out for me because it is very easy to understand, with upper bars, all the features, and the file transfer functionality."
"TeamViewer Business has positively impacted my organization by boosting efficiency since you do not need to be physically available to the client to troubleshoot or help them."
"TeamViewer has positively impacted my organization because it has helped us in saving a lot of time, as the process of conveying instructions is much simpler now, and we are able to provide better online training to our new staff."
"The implementation is quite straightforward."
"I recommend it as a solution for remote disk users."
 

Cons

"Intune's areas for improvement revolve around security and certificate management."
"I cannot think of any particular features which I consider to be most valuable."
"In the past, I raised some tickets for the enhancement feature, which was missing in Intune."
"The worst aspect is the reporting."
"Intune's third-party patch management could be better. It should be easier for the average system admin to keep non-Microsoft applications updated."
"Intune could be improved by expanding its third-party patching capabilities for a more comprehensive solution."
"One area for improvement is app deployment. Another is the Windows update rollout. If you're rolling out an object to a device that's offline, Intune stops trying to reach this device after it sits idle for a bit. We are forced to find a workaround that could help manage that."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"There could be a section in the menu describing the new features and changes."
"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."
"We miss the possibility to communicate via head-set in ISL."
"They need to better advertise the features."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"The business interface is clunky and not well-documented."
"The performance could always be better."
"The security could improve in TeamViewer."
"There is a paid version of this solution with more features available. However, they should provide more free features to the user, such as factor authentication."
"Every now and then you'll get a silent crash and you relaunch the application. But it happens no more than with anything else in the Windows environment."
"Support for mobile devices from Linux has been missing since the Native client was rolled out. This was a nice option, especially when trying to walk somebody who was struggling to understand something on their phone."
"If they could figure out a little better solution for the iOS stuff other than just a screen share, even though it's an Apple thing, and Apple doesn't like to give up control of their devices."
"On occasion, when remote connection process can't connect to a machine, the error messages aren't always helpful to tell you why you can't connect, as the message doesn't help troubleshoot whether it is too slow, too much interference, etc. I usually have to run to another computer and figure out what is going on, then restart it. The diagnostics could be improved."
 

Pricing and Cost Advice

"Intune is cost-effective as it is included in some of the Office 365 packages."
"The pricing is not cheap, especially with inflation. They've had to increase their prices. It's not excessive, but alright."
"On a scale of one to ten with one being the cheapest, the cost of Microsoft Intune is a five."
"Microsoft Intune is available for individual purchase at a low per-device cost."
"The purchase of the product was handled by someone else."
"We use Defender ATP and E5 licenses."
"The tool is cheaper than our company's other MDM tools."
"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."
"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."
"We have a permanent license and the price is reasonable."
"We use the 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."
"The version of the solution we are using is free."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"We are using the free version of TeamViewer."
"There is a free and paid version of this solution. I am currently using the free version."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
