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

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

"When comparing Microsoft Intune to Jamf, Microsoft Intune is superior."
"This product allows us to restrict users who have access to the system, or to Office 365."
"Intune does consolidate all endpoint and security management tools into one place, making everything easier to manage."
"It is absolutely a positive investment."
"Microsoft Intune is a must and should be needed for this time, for this hybrid model period, and I highly recommend this product for employees, education institutions, or device management."
"Microsoft Endpoint Manager is not expensive overall, especially for small environments."
"Microsoft Intune is cost-effective and easy to use, so I can recommend it."
"The core management feature in Intune is invaluable to us, especially considering the challenges we often face with System Center when pushing external updates."
"Without ISL Online, I would not be able to work from home."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"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."
"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."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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."
"We can also monitor our systems at any time from practically anywhere."
"The product is quite stable. The performance is good."
"Easy-to-save access to remote machines: TeamViewer allows you to save machines to your account, which allows you to remote into a machine with ease."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"The solution is user-friendly and very flexible."
"TeamViewer is useful for accessing data and systems remotely. Using this application, I can access other computers using an ID number that I provide to the users whose laptop I would like to access."
"Unattended access with single login."
"With an image, you can see immediately what's going on. You can run some tests. Without the solution, you need to do everything by telephone. It's not even thinkable."
 

Cons

"The documentation about the custom image setup could be better. Although Microsoft provides the steps to configure Intune or set up or deploy Intune, it doesn't have much information related to custom images. If you ask, "how can we deploy the custom image?" There is no information. The steps they mention ask you to connect to your on-premises environment or create your own image on the cloud itself once there is connectivity. But I needed to go to multiple websites to get all this information. I had to figure out how to upload the custom image if you want to use the on-premise custom image for Cloud PC. If you have the proper subscription, you must have the right access, like global admin or owner. Then you can add your custom image to that. There are no steps mentioned over there. Microsoft Intune doesn't have Chrome browser support. I would like to have that support because they will want it if we pitch the product to clients."
"I am not involved in the day-to-day with Intune, but we have gone with a different product for updating mobile device software. We do not integrate many of our mobile devices that are not Microsoft-based devices, such as Dell laptops, with Intune."
"The UI is not user-friendly and has room for improvement."
"An issue we have run into with Microsoft Endpoint Manager is that we cannot patch third-party products like Adobe and Chrome with it."
"It would be great to see on-premises mailboxes and for the solution to have geofencing capabilities."
"It would be helpful if there was proactive remediation."
"From my level of analysis, the feature I would prefer to see added to Microsoft Intune is extensive support. Anything that helps to diagnose the problem and solve it would be useful."
"The most significant challenge is reporting and monitoring. The reporting accuracy for deploying applications and all aspects of Intune needs to be improved."
"We miss the possibility to communicate via head-set in ISL."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"It would be helpful if they had iSupport for supporting Apple phones."
"They need to better advertise the features."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"It would be helpful if they had iSupport for supporting Apple phones."
"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."
"It's pretty limited on the options they have."
"It needs to have proper authentication."
"I believe latency can be optimized, and security control sometimes goes over the top and feels excessive."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"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."
"Sometimes it lags. They need to optimize it a bit."
"But still, I think the price factor for small business."
 

Pricing and Cost Advice

"Intune's pricing is competitive. For example, the license of Blackberry's Enterprise Mobility Suite was costly, but Intune is affordable. It is included as an additional feature when you buy security enhancements for your organization. For example, let's say I have fifty users in my organization and all of them are using Microsoft cloud services, like Teams, Office 365, and OneDrive."
"While I don't have access to high-level financial information, I believe we have achieved lower costs with this implementation."
"There is a license needed to use the solution and we are on an annual license."
"I have no comment on pricing of the solution."
"Microsoft Intune is moderately priced. There is a monthly license required to use the solution and it is approximately eight dollars per month."
"All security solutions worldwide are expensive. Microsoft has allowed a small scale of features within Microsoft Intune for cost-efficient solutions. If you want the full suite, you need to invest more to gain better security features."
"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."
"Microsoft Intune is more expensive than other solutions, but it offers a wider range of features and control."
"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."
"There is a free and paid version of this solution. I am currently using the free version."
"I used the free version of TeamViewer."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"The price was cheaper than what we were previously paying. At the time that we went with TeamViewer, we were using ShareConnect. The TeamViewer package was about half the cost and able to have a bigger number of users."
"The solution's pricing is reasonable."
"...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."
"There is no license needed to use TeamViewer."
