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 Autopilot feature is the most valuable because it saves significant time on managing devices."
"It is user-friendly, and the performance is also good. It is a convenient product"
"The ability to work from all over the planet is valuable. You just need a functioning and working Internet connection."
"We have one MDM that works with Windows, iOS, and Android."
"It is very easy for me to configure all the things. Once I create policies and applications in Intune, it is very easy for us to enroll users."
"Microsoft Intune is far more efficient and faster than MECM."
"This solution saves us a lot of time once it's implemented."
"It supports end-users who tend to lock their devices quite frequently. Its conditional access policy helps us keep the users logged into their devices."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Setting up the solution is easy and there's no maintenance involved."
"Good communication is a key to good business and ISL helps a lot."
"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 can also monitor our systems at any time from practically anywhere."
"Without ISL Online, I would not be able to work from home."
"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."
"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. I was able to do that without much of an issue. It is also a secure solution."
"Our computers are spread amongst six physical locations, and TeamViewer reduces the need to travel to those offices to help staff."
"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 most valuable features of TeamViewer are the high performance and it is not complicated to use, neither for me nor for the one I'm helping."
"There have been a couple of times with the handy remote access feature, where I have been asked for something at eight o'clock on a Thursday evening and it is on my desk machine, but I am driving back to my office. With TeamViewer, I can just stay at my home machine, connect to my work machine, and get the data needed without having to drive back across town."
"The product is quite stable. The performance is good."
"I have been satisfied with TeamViewer overall."
"It's worth every penny; I would recommend it any time."
 

Cons

"Logs and similar deployment/remediation detail for application delivery to Windows 10 computers should to be improved Additional application deployment options e.g. MSI deployment with more complex parameters or additional side-by-side files, and non-MSI deployment options."
"Microsoft Intune has a few areas where it could improve, such as faster policy and app deployment, a better user interface, stronger support for non-Windows devices, improved reporting and visibility, easier troubleshooting tools, and more transparent pricing."
"There should be more focus on mobile device security and integration."
"The platform is incredibly slow and could be more responsive. Specifically, when making changes to security policies, I would like to see those changes take effect more quickly."
"I know that their AI pieces are at the infancy stage, but allowing users to do more tagging for information would be an interesting thing because Intune also directly integrates with Azure. Because a lot of the devices are hosted with that, you also get a lot of tagging of user data and other things like that."
"It just doesn't handle software updates well at all by itself. You need to be a scripting wizard to make those happen properly, or you use third-party tools."
"There is improvement needed in integrating with the installed Office solutions versions, such as Office 2019. The Office 365 integrates without a problem."
"Applying security recommendations can be difficult in Microsoft Intune. Sometimes, they give you recommendations, but you need a different server to manage the pieces, or you have to go to each device individually. However, it has been improving. Before, there were certain policies you could not implement directly in Intune, but now I see progress. I would like to see more improvement in policy management, similar to how we used group policies on-premises."
"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."
"We miss the possibility to communicate via head-set in ISL."
"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."
"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."
"There could be a section in the menu describing the new features and changes."
"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."
"What bothered me the most was that when I connected to the computer at the office, I was afraid that someone would turn on the monitor and watch what I was doing."
"Sometimes it gives problems, with the button not working, and I was unable to log in."
"It becomes complicated to switch from one monitor to another for different windows."
"The connection and reconnection sometimes lag and can cause problems."
"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."
"I don’t see any areas where improvement is needed."
"You can't configure multiple, unattended control passwords on the Mac. On the Mac, there's only one. On Windows, there are multiple unattended control passwords. I have people in different departments. My infrastructure people need to control a server and my developers may need to go into that same server. But I don't want them to have the same password... on the Mac, it can be done but it's extremely clunky and problematic."
"TeamViewer could be more secure."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
 

Pricing and Cost Advice

"If you're subscribing to Premium or E3, there are no additional costs for Intune, it's included."
"Cost is not my department, but the product is included in the E5 license that we already pay for every user, so no additional cost is incurred."
"With our standard E5 agreement with Microsoft, there have been no pricing concerns. Introductory professional services, like a fast-track service, were included with our E5 membership, and there have been no additional costs."
"We have a limited budget for security investments, so Microsoft should consider reducing pricing in our region. This would make investment more viable, especially since larger businesses in other countries can afford it easily."
"I would rate the price a four out of ten with ten being the most expensive."
"There is a license needed to use the solution and we are on an annual license."
"For Microsoft 365 E5 clients, cost is not an issue as this product is one of the benefits."
"The pricing for Intune and the competitor products are all within the same range, there is no true advantage when it comes to cost."
"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 are not using the solution for commercial use therefore it is free to use."
"The solution's pricing is reasonable."
"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)."
"The cost is in the thousands of dollars per year."
"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 has multiple licensing options."
"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."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
