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

"I appreciate how clear Microsoft Intune is."
"It is easy to use and easy to roll out with low impact on users; it is stable and scalable as well, and the central administration con dashboard is very easy to use and provides very good oversight on all that needs to be monitored."
"This solution saves us a lot of time once it's implemented."
"The most valuable feature is the UEM capabilities."
"At the moment, Autopilot is the most valuable feature."
"By using Microsoft Intune we can control which websites the users can go to and it provides a secure environment for our employees using their laptops that are having access from home. We have installed Intune to control the user's environment minimizing the chances of any hacking."
"It has helped with compliance. It has helped to ensure that devices comply with the organization's policy. If they are not compliant and secure, they cannot access the resources."
"The synchronization of Intune with other Microsoft solutions is a valuable feature."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"We can also monitor our systems at any time from practically anywhere."
"Without ISL Online, I would not be able to work from home."
"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 like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"The most valuable feature is safety."
"ISL Online is easy to use and it provides a single platform for various challenges we face in IT."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"Ease of use was the number-one thing. It's an industry leader for ease of use, specifically on the client-side, which is the absolutely critical thing. If I want to connect to somebody, how easily can I — without seeing their computer — walk them through the steps to install it to a point where I can key in the code and help them resolve their situation?... TeamViewer is just a dead-solid, easy answer."
"The most valuable feature of TeamViewer is its ease of use."
"We use TeamViewer for our help desk to manage and troubleshoot remotely."
"I have been satisfied with TeamViewer overall."
"The TeamViewer system has some built-in security. The TeamViewer client connects to the TeamViewer host securely. Only a certain number of authorized users on our side have access to the system. Even within that, an individual endpoint can be assigned to a group, where not everybody has access but, rather, just one or two people who are part of a support team might have access to that particular device. So TeamViewer has given us tools to be able to segregate who has access to different things."
"In the years I have used TeamViewer, everything that I missed was already added."
"TeamViewer has a good interface."
"It saves trips to customer sites, which saves time, and I am able to get in there remotely and fix things."
 

Cons

"Microsoft Intune is currently overpriced."
"The documentation about the custom image setup could be better."
"I rate Microsoft support between six to eight. The support often involves third parties hired by Microsoft who are knowledgeable, but sometimes the help I receive is not adequate."
"I would like more clarity on how Intune is migrating control from Active Directory group policies, especially as we move over to Windows 11. It seems inefficient to manage some settings in Active Directory and others in Intune."
"The solution could improve by having better integration with Apple."
"The reporting dashboard is really limited."
"A more incisive reporting tool with automated progress updates and graphical representation would be beneficial, as the current manual method lacks efficiency and visual clarity."
"Intune has limited integration with non-Microsoft solutions."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"I would like to be able to access and manage all brands of smartphones."
"They need to better advertise the features."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"It would be helpful if they had iSupport for supporting Apple phones."
"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."
"The one area which needs improvement for both the standalone and enterprise versions would be inter-operability between versions."
"TeamViewer can improve connectivity. I had some problems connecting to my clients and now I use AnyDesk."
"TeamViewer can improve by making the interface more user-friendly. It looks very basic, they can make it more modern and easy to use."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"We'd like to be able to work from mobile to desktop and vice versa. We'd like more mobility."
"I am not sure about all the features of TeamViewer, but if they have no voice communication or file transfer features they should add them."
"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..."
"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."
 

Pricing and Cost Advice

"Pricing can be improved."
"My team members bundled it together with their Microsoft solutions, including Microsoft 365 and related products."
"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."
"Licensing depends on how you are providing support to your enterprise, whether it's device-based or user-based."
"With one user base license, we can use Intune for up to five devices. However, with Soti MobiControl, each license is tied to a single device, meaning one license is dedicated to one device only."
"The Intune license model is costly."
"We don't get Intune as a separate module. Most of the time, we use it within an enterprise agreement like E3 or E5. Those licenses are at a good price, but what is annoying is that every single year they go higher."
"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 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."
"The pricing is a little bit on the higher side."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"The solution's pricing is reasonable."
"We are using the standard free version of TeamViewer."
"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)."
"TeamViewer offers a free version to try. Download and give it a shot. See what it's like and if you like it, then buy the license for it."
"It does what I need it to do but I think it's expensive. It wasn't easy for me to get approval from the company to get it... It's costing us about $700 a year, per license."
