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

"Overall, I would rate Microsoft Intune as eight out of ten."
"The feature of remotely wiping devices in Microsoft Intune is what I prefer the most."
"I like how Microsoft Intune lets me lock down the email profile and make it accessible only on certain devices."
"Intune provides full visibility into all active mobile device users. If their devices are noncompliant with our security policies, I have the flexibility to update them remotely."
"It is helpful for managing devices anytime and any place without requiring dependency on the local networks."
"This product works very well for companies already using the full Microsoft suite."
"Intune has automated the deployment of patches and applications, which is more efficient and easier. It allows us to deploy applications, packages, Windows updates, and security updates like BitLocker encryption more efficiently and easily."
"Microsoft Intune does a great job of helping protect our environment."
"We can also monitor our systems at any time from practically anywhere."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"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."
"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."
"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."
"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."
"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."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"The solution is scalable."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"The product is easy to install."
"It's a user-friendly product."
"TeamViewer is fast and easy to manipulate."
 

Cons

"It should be easier to define policies and comply with those policies."
"Intune could add more Linux security features and more integration with on-prem devices. The application deployments can also be improved."
"The support is not particularly good. Sometimes when you open a case with Microsoft, you end up resolving the issue by yourself."
"There could be more competent processes and improvements in the policy space."
"Microsoft Intune has potential for improvement; I would like to see a lot more customization in the reporting tools."
"The solution could improve its flexibility."
"Improvements are needed in Microsoft Intune's enterprise app management, including support for more applications in app patching, boot batching, and discovery. I also hope the cost of Remote Help will decrease because it's a much-needed Intune function. Our customers need that capability, or they will buy it from a third party at a premium."
"Intune's areas for improvement revolve around security and certificate management."
"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."
"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."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"I would like to be able to access and manage all brands of smartphones."
"We access the solution through a VPN, which improves our security. However, earlier this year, around the beginning of March, a CVE in the TeamViewer client allowed remote connections to other network systems, which was concerning. You could have unintentionally gained admin rights if you didn't update TeamViewer promptly. It's crucial to always keep it updated to prevent such issues. The tool should consider implementing two-factor authentication to improve such security holes. It should also integrate good security updates, which should be implemented automatically."
"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."
"The installation and the update agent could improve."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"Voice communication and screen communication or face-to-face communication could be improved."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"It becomes complicated to switch from one monitor to another for different windows."
"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."
 

Pricing and Cost Advice

"It comes as a bundle, so you do not really know what the prices are. Microsoft does not break it down to the user cost for us. It is just bundled with our E5 license."
"The pricing is good because customers are not complaining about it."
"It's a bit expensive from a licensing perspective, especially as we look to have organizations with tenants across the globe."
"The clients pay for a license and each can have a different type of license, such as an E3 or E5."
"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."
"If you're subscribing to Premium or E3, there are no additional costs for Intune, it's included."
"It comes with the E5 plan. We bought the E5 plan from Microsoft."
"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."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"We are using the standard free version of TeamViewer."
"There is a free and paid version of this solution. I am currently using the free version."
"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."
"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."
"The cost is in the thousands of dollars per year."
"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."
"TeamViewer is $600 or $700 per port per year..."
