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

"The main benefit for us with Microsoft Intune is centralized management of all devices, allowing us to apply one policy across the company from one location."
"Intune's security features for Apple iOS and Mac OS are helpful. We can check enrollment, manage public and private settings, and manage the organization's data using security key features."
"The security posture is very good. It's very customizable."
"The biggest asset is the range of device management options available with Intune, whether it is a Windows device, a Linux device, a Mac device, or mobile devices."
"Intune's integration with Defender and other security solutions is valuable because it offers a view into different security vulnerabilities and enables us to secure them more effectively."
"The feature of remotely wiping devices in Microsoft Intune is what I prefer the most."
"Intune's integration with Microsoft 365 is exceptional."
"The best features include the management, which is quite good, and endpoints."
"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 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."
"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."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"This solution is straightforward to use."
"The most valuable feature of TeamViewer is the remote access connection. Additionally, it is easy to use."
"The dashboards they have are good."
"The most valuable feature of TeamViewer is its ease of use."
"From my perspective, the most important is the login."
"TeamViewer has a lot of options for deploying the Hosts, where you can mass deploy them very easily, and you can pre-configure them."
"TeamViewer Business has positively impacted my organization because it saves time, as I don't have to go to the customer's place to make some connections or configurations; I can make it remote and very easy."
"The most valuable features of I use TeamViewer are the ease of access and frequent updates."
 

Cons

"Intune is not the most user-friendly mobile device management platform available."
"Intune's server management could be better. If it could incorporate more features from System Center into Intune's Configuration Manager, it would be beneficial."
"In Microsoft Intune, there is significant slowness, and there needs to be more logs when we deploy software, parameters, or scripts to troubleshoot problems and errors in the interface, workstations, and Android devices."
"Enrollment into the Microsoft Intune service can still get easier, especially for legacy-managed systems, such as how we get it from a GPO or an SCCM configuration into Intune."
"We haven't really gone through all the features of Intune. We are just discovering them. Every day, we see a new feature that we want to apply, but what will be great for Intune is to be able to deploy apps in a simple fashion. We should be able to easily install various apps on the Windows platform, iOS, and Android. Currently, we have to write some scripts. It's not as straightforward as we would like it to be. It should be simplified so that we can do it just with three clicks—next, next, finish—without needing to write a script."
"To make it a perfect ten, it would be helpful if there was a better way to troubleshoot user issues, as I've had a few users with corrupt files before and had to redeploy it without knowing the root cause."
"No option to do end-to-en macOS management. Slow implementation of policies."
"Intune could add more features that are relevant to the core application control functions. For example, it would be helpful if it had more control over the on-prem environment from the cloud platform. Greater Teams availability in the Saudi market would also be helpful."
"They need to better advertise the features."
"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. 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."
"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."
"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."
"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."
"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."
"I would like to see something like a TeamViewer mobile application for iOS or possibly Android. I think this would be fantastic given how technology is evolving today. It would be beneficial to use it with your smartphone."
"In the next release, I would prefer to have a voice integration and collaboration feature to support multiple teams simultaneously."
"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."
"TeamViewer has a legacy and may not be using the latest UI trends."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"The solution could have better scalability."
 

Pricing and Cost Advice

"Licensing depends on how you are providing support to your enterprise, whether it's device-based or user-based."
"It's affordable. In comparison to the competitors, the price depends on what features you need from Intune, but it's affordable. There are no hidden costs, but there are some features that go for a premium price. Those are the add-ons for which you have to pay extra."
"The pricing is competitive, but it is not cheap."
"Its price is in the medium range. It is acceptable because you're paying for the features. I am not aware of any additional costs."
"The E5 license is expensive."
"We have a limited budget for security investments, so Microsoft should consider reducing pricing in our region. This would make investment more viable, especially since larger businesses in other countries can afford it easily."
"The price is very reasonable."
"It is cheap, but as compared to Google, it is costly. Google is cheaper, but quality-wise, Microsoft Intune is better."
"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 used the free version of TeamViewer."
"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."
"We are not using the solution for commercial use therefore it is free to use."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"We have a permanent license and the price is reasonable."
"The version of the solution we are using is free."
"We use the free version of TeamViewer."
"TeamViewer has multiple licensing options."
