Enables management of multiple operating systems with a single license
The best feature is that it's a Microsoft product, so if anything goes wrong, we get quick support for anything required. Remote system functionality allows us to sit anywhere and take control of any device via remote management. We can enhance security for clients' laptops with built-in Microsoft Defender, which is available with the Microsoft Intune license. We use it for reporting purposes through endpoint analytics. When pushing scripting, there are two types available: remediation script and reservation script. Through endpoint analytics, you can push defender policies to clients. It helps with reporting, inventory updates, and monitoring tenant status health.

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.

Remote support has transformed my work and now saves time with fast, secure file transfers
What I appreciate about TeamViewer Business is the reliable and secure connection experienced during file transfers or troubleshooting processes, even when we have to restart the PC; we are still able to connect to the customer quickly. TeamViewer Business offers a free version for both personal and business use. The free version actually covers all the features needed for secure remote connection, which is one of the positive aspects I have experienced. The secure connections and great file transfer feature are super fast and secure, with reliable features during the process of reconnecting and connecting back to clients. Back in 2009 and 2007, the internet did not have the faster features it has today. TeamViewer Business's file transfer feature has made things easier. Instead of downloading a file from a source like HP.com, we just have to transfer the file from our system to the customer securely and quickly. Many technical support people have benefited from that feature, which I find very reliable.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It helps us manage user certificates."
"If the product works, remote access will be a benefit. To this point we have not had reason to have confidence in achieving that access."
"I can reach devices or computers over the internet. I don't need to worry about the network connectivity between the offices. I can manage any device. That is the most important part."
"One valuable feature of Microsoft Intune is the enrollment process, which is user-based, making it easier to manage compared to AirWatch."
"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"The biggest thing for us is enforcing logins only from devices that are managed by Intune."
"Overall, my user experience with Microsoft Intune has been great."
"Internet-based access with security is what I have found to be most valuable. It is also a stable and scalable solution."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"The most valuable feature is safety."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"I personally really appreciate the file transfer feature as it is really easy to use."
"This solution is straightforward to use."
"It is quite simple to set up."
"It's pretty easy to use. Just key in an ID and password and connect. For meetings, just enter the meeting ID and connect."
"It's very beneficial and time effective on how we are able to provide quick support. We've quadrupled our effectiveness as an IT support because we have cut down all that unnecessary travel time, even between floors."
"TeamViewer Business has positively impacted my organization by giving us the ability to provide clients with a good experience and to fix bugs quickly while accessing their computers."
"I have been satisfied with TeamViewer overall."
"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."
"The TeamViewer system has some built-in security. The TeamViewer client connects to the TeamViewer host securely. Only a certain number of authorized users on our side have access to the system. Even within that, an individual endpoint can be assigned to a group, where not everybody has access but, rather, just one or two people who are part of a support team might have access to that particular device. So TeamViewer has given us tools to be able to segregate who has access to different things."
 

Cons

"A major challenge is making all the products work within device management solutions like Intune. It would be beneficial if Microsoft removed support for older products much earlier in the process."
"Back in 2020, there were significant problems with report accuracy, particularly regarding web patching."
"The reporting and cost have room for improvement."
"You can have a bad day where 80% of the enrollments failed. The next day it's running with the same devices without any changes, and you don't know why."
"Technical support can be challenging when resources shift, requiring repeated explanations. Support from India sometimes provides information without the right solution."
"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."
"Since GMS is unavailable in China, we currently rely on device administrator enrollment for managing Android devices there."
"Lacks the ability to deploy more ways of management, managing devices and processing the policies."
"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."
"There could be a section in the menu describing the new features and changes."
"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 helpful if they had iSupport for supporting Apple phones."
"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 need to better advertise the features."
"I would like to be able to access and manage all brands of smartphones."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"I think TeamViewer has many better options, and I suggest TeamViewer should also offer voice communication with my clients because writing is acceptable, but voice communication is much better."
"On occasion, when remote connection process can't connect to a machine, the error messages aren't always helpful to tell you why you can't connect, as the message doesn't help troubleshoot whether it is too slow, too much interference, etc. I usually have to run to another computer and figure out what is going on, then restart it. The diagnostics could be improved."
"TeamViewer could work on performance latency in slower internet connections by optimizing screen refresh rates during remote sessions, especially when transferring large files or using graphics-heavy applications."
"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."
"The performance could always be better."
"TeamViewer Business can improve in terms of price and the complexity of licensing, which is a drawback, especially for smaller teams or casual users due to frequent license changes and forced upgrades."
"I'm not sure if they provide good quality audio alongside screensharing."
 

Pricing and Cost Advice

"This cost is approximately $30 USD per user per month."
"The pricing for Microsoft Intune is reasonable. Our clients are satisfied."
"I liked the tool's pricing until P2 came into effect. I am unsure about the current value versus the cost of the new licensing model."
"It is not expensive."
"Microsoft Intune's costliness stems from licensing fees and the overhead associated with its management, user experience, and device remediation."
"Intune is inexpensive. It also comes bundled in some Office 365 licenses, so you can choose to purchase it separately or as a package."
"Intune is cost-effective as it is included in some of the Office 365 packages."
"There is a license required to use the solution. If you're core users in Office 365, for example, you have Outlook email and E3 license, this is only email. You have to buy an EMS license to have Microsoft Intune. It is expensive."
"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."
"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."
"We are using the standard free version of TeamViewer."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"We use the free version of TeamViewer."
"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."
"We are using the free version of TeamViewer."
"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."
