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 biggest benefits of Intune are the ability to push changes and the added security. When we moved forward with Defender, we onboarded all those machines automatically. That helps dramatically. For a while, we were left with machines that weren't protected. We could see where people had done things they shouldn't have done, and Defender saved our skins a few times. It didn't happen a lot, but it happened enough that it made us glad we made that decision."
"I like the group policy management feature, which performs application monitoring and device enrollment."
"If any user tries to access company data, it directly interacts with the conditional access policy. This helps us protect our data and set the criteria for how data can be accessed and shared."
"This product works very well for companies already using the full Microsoft suite."
"Maturity makes it a stable product."
"Microsoft Intune has transformed my organization; we are managing to scale the Intune deployment across all our regions efficiently, and it works perfectly for our needs."
"I would rate the stability of Microsoft Intune nine out of ten."
"There are many features in Microsoft Intune. For personal mobile devices, MDM is what I most prefer."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"Setting up the solution is easy and there's no maintenance involved."
"We can also monitor our systems at any time from practically anywhere."
"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."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The product and platform work well. That is why I have stay with them so long. The stability has typically been good."
"Getting started with TeamViewer was easy, with a very straightforward usage"
"Ever since we have been using TeamViewer Business, because of how quick it is to connect to a user across the globe, we have been able to close tickets rapidly."
"The solution is a very good tool for monitoring and for remote access. Anyone is able to use it, it is simple to use."
"It's very easy to set up."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"From my perspective, the most important is the login."
"TeamViewer is a step ahead of solutions like, for example, AnyDesk."
 

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."
"While Intune works perfectly well, the only potential downside is that the deployment could be a bit complex for some users."
"A more incisive reporting tool with automated progress updates and graphical representation would be beneficial, as the current manual method lacks efficiency and visual clarity."
"Reporting needs improvement."
"Sometimes, the process is unsuccessful when we attempt to reset a device and wipe the data using Intune."
"Intune could be improved by expanding its third-party patching capabilities for a more comprehensive solution."
"The reporting could be improved, as it's pretty poor compared to other products of this type."
"There needs to be more support for Mac operating systems."
"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."
"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."
"They need to better advertise the features."
"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 have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"TeamViewer is expensive, and you get a limited number of connections for your money."
"TeamViewer could be more secure."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"The security could improve in TeamViewer."
"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."
"TeamViewer Business's scalability is bad because it's very expensive."
"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."
"The business interface is clunky and not well-documented."
 

Pricing and Cost Advice

"Microsoft Intune has been incorporated into our Microsoft E5 licenses."
"Pricing can be improved."
"Microsoft Intune is moderately priced. There is a monthly license required to use the solution and it is approximately eight dollars per month."
"While I don't have access to high-level financial information, I believe we have achieved lower costs with this implementation."
"I would rate the price a four out of ten with ten being the most expensive."
"There is a cost benefit of using Microsoft Intune because of the packaging with other Microsoft products."
"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."
"It is reasonable. When you have Microsoft 365 E3 or E5 license, it is already licensed in that license. So, you could say it is free."
"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 no license needed to use TeamViewer."
"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."
"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 version of the solution we are using is free."
"It would be nice if it is cheaper."
"We're using the free version. We do not pay any licensing fees."
"The solution's pricing is reasonable."
