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.

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 most valuable feature of Intune is the central dashboard for compliance and policy management."
"The most valuable features of Microsoft Intune include remote updates. The update runs in the background, so there's no need in most cases to go on-site to do it."
"The thing I appreciate most about Microsoft Intune is that the management of the devices was very simplified. We have all machines connected to it at all times, whether they are in the office or working from home."
"It has improve our organization through the remote management of non-domain joined devices."
"A great solution for anyone wanting a modern endpoint device management solution."
"We are transforming our flat network by adopting different cloud solutions, and our own applications are hosted in the cloud. Intune ensures our security throughout our entire cloud-based system, improving our security posture."
"It's normally able to meet 100% expectations of our customers."
"Microsoft Intune is extremely important from a security perspective to ensure devices are compliant and gives us the efficiency to deploy apps automatically to a large number of users without the need for interaction from a client side, which is always helpful."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"We can also monitor our systems at any time from practically anywhere."
"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 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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"The most valuable feature is safety."
"Quicker and easier to connect to our customers’ PCs to resolve software issues."
"Saves travel time, and wide support of platforms allows for a single solution."
"Nothing else compares to it at the same level."
"Remote desktop sharing is one valuable feature of the solution."
"It’s so great for when you need to provide remote support, allowing us to troubleshoot in real-time, with good configuration and structure, easy installation, strong stability, good scalability, and it isn’t expensive at all."
"Ultimately, however, even with all of its warts and problems, it's still the best, most reliable and most affordable remote control product, at least for our environment."
"The solution has worked flawlessly; it’s stable and reliable, with no bugs or glitches."
"We also use it a lot for remote site assistance. We've set up our internal authentication for unattended access to our remote sites. That makes it very easy and convenient to remotely connect with our users and our client machines whenever we need to. It's set as a direct, secure connection. As long as the station has internet access, we can see it and it makes remote support very simple."
 

Cons

"There were several bugs with stability."
"My experience with them was very bad. They don't know about their own product."
"The solution's app deployment needs to be improved."
"There are areas that have room for improvement in Microsoft Intune, particularly regarding integrations."
"Technical support is not that great."
"The technical support could be improved."
"The closest Microsoft Intune can be to GPOs, the better. There needs to be more granularity on application deployments. However, they have done better recently with the application deployments."
"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."
"I would like to be able to access and manage all brands of smartphones."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"We miss the possibility to communicate via head-set in ISL."
"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."
"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."
"I would like it to have the ability to stay connected for longer times."
"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."
"It's not the program itself that's an issue, but there is a need for some better documentation on how to use the web portal Management Console. That seems to be a bit lacking in directions, if you aren't paying attention and you don't know what to do. Better documentation would make it a little bit easier to set things up in different groups and share groups between people."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"I'm not sure if they provide good quality audio alongside screensharing."
"The stability of TeamViewer is good, but it could be better."
"It would be beneficial to have group functionalities to separate access when many consultants want to access different departments or clients at the same time."
"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

"We have the business premium licenses for the solution."
"I rate Intune an eight out of ten for affordability. It's bundled with the 365 licensing, which is competitive overall."
"Microsoft's licensing is more flexible and adaptive than its competitors."
"Microsoft Intune's pricing is reasonable."
"Its price is fair. It's a normal price. It isn't too expensive or too cheap."
"It's a bit expensive from a licensing perspective, especially as we look to have organizations with tenants across the globe."
"The price for Intune is fair."
"The product is offered as part of a Microsoft standard bundle. The pricing can be competitive to Airwatch, and Maas360."
"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 using the standard free version of TeamViewer."
"The solution's pricing is reasonable."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"It would be nice if it is cheaper."
"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."
"There is a free and paid version of this solution. I am currently using the free version."
"The version of the solution we are using is free."
"The cost is in the thousands of dollars per year."
