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 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."
"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 solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"Good communication is a key to good business and ISL helps a lot."

Cons

"The only issues I have had with Microsoft Intune were with applications where if they are not an MSI file, I cannot really upload it as an application."
"Yes, there are a couple of issues with stability."
"It needs certificate provisioning for S/MIME purposes."
"We do not utilize Microsoft customer service and technical support since it is generally a waste of time."
"Improvements can be made by allowing server integrations since it is an area where the product currently has shortcomings."
"There should be more predictability in the release cycle. We don't feel we have any control over when new updates come out, and whether there are changes to the backend functionality or to the user interface. Updates just happen."
"In terms of the admin experience, it is straightforward, but the Windows enrollment experience could be improved. Sometimes, for enrollment, we have to reset devices and re-enroll them."
"I cannot think of any particular features which I consider to be most valuable."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"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."
"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."
"There could be a section in the menu describing the new features and changes."
"There could be a section in the menu describing the new features and changes."
"The solution could improve by increasing or removing the time limitation on the use of a session."
"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..."
"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."
"It does what I need it to do but I think it's expensive."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"I have noticed that when I access another person's computer, sometimes the tab is visible, and sometimes it is not, which can be difficult."
"Unfortunately, the software is hit or miss when it comes to iOS devices, especially Macs."
"I believe there are aspects of TeamViewer that could work better, particularly in the integration of various tools."
 

Pricing and Cost Advice

"The tool is cheaper than our company's other MDM tools."
"Its price is fair. It's a normal price. It isn't too expensive or too cheap."
"It's reasonable. They're not giving it away, but it's reasonable."
"Intune is available as an individual product, but it also comes with Office 365 Premium or an Enterprise license, and the price varies for each version."
"Pricing depends on the features. Microsoft offers special packages if there are more than 10,000 users, and you may be able to get a reduced rate."
"The clients pay for a license and each can have a different type of license, such as an E3 or E5."
"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."
"The purchase of the product was handled by someone else."
"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 price of the license could be less expensive."
"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 solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"The cost is in the thousands of dollars per year."
"TeamViewer was willing to give us a one-year package. Whereas, a lot of the other companies that we explored were paid by the month or quarter. It's just easier for our finance people at the college if we can make a one-time yearly payment."
"We have an annual subscription that is just under $1,900 with no additional costs. We get these promotions about upgrades and stuff like that, but we haven't had a need to add more seats. Users can also use TeamViewer for home use with a non-commercial free license."
"The cost of the licenses depends on how you buy them. They just had a buy one get one free deal going, and they do that every once in a while. Where you buy one license, and they will give you the second one free, or you can try to get discounts. Most of our licenses that we have we tried to do something like that just to save some money."
