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 pricing for Microsoft Intune is reasonable and our clients are satisfied."
"It is a comprehensive security solution that not only controls access to enterprise resources but also tracks and prevents unauthorized access, ensuring the protection of sensitive data and preventing potential data loss scenarios."
"Technical support is good."
"We are able to deliver applications fast to our mobile workloads so that users can make use of it instantly."
"The solution is scalable. We currently have tens of thousands of users within our organization using the solution."
"Microsoft Intune has helped us by improving our security posture, leading to fewer security problems, and helping us understand where we have issues."
"Microsoft Intune has definitely reduced management burdens."
"The main value of Microsoft Intune is better asset management from a security perspective, ensuring that the security baseline is enforced on all devices, including mobile devices."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"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."
"Good communication is a key to good business and ISL helps a lot."
"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."
"The most valuable feature is safety."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"Without ISL Online, I would not be able to work from home."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"If someone is looking for a remote connection and support solution, this is a good choice."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
"TeamViewer has been one of the easiest, right off the bat products, that we have employed at the college. We have had no issues. It's been one of the easiest solutions to pick up."
"TeamViewer is fast and easy to manipulate."
"We've been very happy with the solution over a number of years."

"I use TeamViewer to connect to other workstations, Mac, or PC without a VPN connection."
"TeamViewer has positively impacted my organization by improving the way our team communicates and enhancing our efficiency."
 

Cons

"The difficulty of the the roll out is surprisingly difficult considering this product is supposed to be an integrated part of the 365 suite."
"Sometimes, the process is unsuccessful when we attempt to reset a device and wipe the data using Intune."
"My whole team is saying that they would rate technical support a three or four out of ten."
"We would like to see support for Chrome and/or devices for Chromebooks."
"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."
"It doesn't economize when you scale up. We have over 14,000 employees, and we have between 7,500 and 8,000 city-owned or personal devices being used to conduct city business."
"For an existing customer who has an SCCM, it would need to be upgraded to an MECM first before I can introduce Microsoft Intune."
"Automations in Microsoft Intune can be more elaborated; KQL (Kusto Query Language) is available, but if multiple automation options were readily available, which would include PowerShell, KQL, JSON, and different interpreters like VS Code or Python readily available from Microsoft Intune, it would help administration and management much better."
"There could be a section in the menu describing the new features and changes."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"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. At the moment, we combine ISL for visual communication with Skype for verbal communication."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"We miss the possibility to communicate via head-set in ISL."
"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."
"I believe latency can be optimized, and security control sometimes goes over the top and feels excessive."
"The file transfer functionality crashes sometimes."
"TeamViewer can improve by making the interface more user-friendly. It looks very basic, they can make it more modern and easy to use."
"It needs to have proper authentication. I would like to see in-depth integration with Google and Microsoft products, for example. It would be nice to have a cell phone version as well."
"They could give more information about using certain kinds of applications for secure transactions, such as secure file transfers."
"Unfortunately, the software is hit or miss when it comes to iOS devices, especially Macs."
"One thing I have noticed is that TeamViewer does not work so well when the machine you are trying to connect to remotely is not running the same version as your machine."
 

Pricing and Cost Advice

"Its price is quite okay. I wish they provide certain additional features with the same license."
"Intune comes with the licensing that is common for large organizations. However, Microsoft has recently released many add-ons that are very expensive, especially for large organizations or corporations."
"This cost is approximately $30 USD per user per month."
"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."
"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"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."
"The clients pay for a license and each can have a different type of license, such as an E3 or E5."
"The product is relatively pricey, but considering its benefits, I'd say it's fair. The benefits outweigh the expensive licensing fees, especially for large organizations, but medium-sized and smaller businesses may be unable to afford it."
"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."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"...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 has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"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)."
"We are not using the solution for commercial use therefore it is free to use."
"The solution's pricing is reasonable."
"We're using the free version. We do not pay any licensing fees."
"TeamViewer pricing is reasonable... The simultaneous controller licensing model of TeamViewer - compared to LogMeIn’s controlled Host licensing model - seems to benefit us so far. We’re currently saving about 30 percent on licensing cost... The savings from licensing have been eaten up by the soft costs involved in dealing with and working around TeamViewer’s deficiencies in allowing granular control by multiple controllers, and the issues with the various settings that are missing on the macOS Host."
