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 best feature of Microsoft Intune is that it managed the endpoints."
"One of the biggest advantages of Microsoft Intune is that it brings the management of Windows, macOS, iOS, Android, and even Linux under a single pane of glass."
"The most important thing for me is the autopilot feature."
"There are no complaints about the stability. It works one hundred percent of the time."
"The most valuable feature of Intune is the ability to reset a lost device and remove all the data."
"Microsoft Intune has never crashed for me; it always works without fail."
"I have seen a return on investment with Microsoft Intune, as it has saved me resources; previously, I managed my infrastructure with a team of around six to seven members, but after transitioning to the Microsoft Intune hybrid model, I am able to manage it with just one resource, allowing me to cut costs significantly, around 50-60 lakhs."
"The Asset Management and Auto Pilot are valuable features."
"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The most valuable feature is safety."
"We can also monitor our systems at any time from practically anywhere."
"The implementation process is simple."
"It is easy to use and has a pretty good UI."
"The product is easy to install."
"The most valuable feature has been the ability to give control to others for support purposes."
"The most valuable feature of TeamViewer is its ease of use."
"The most important feature of TeamViewer is its ease of use."
"TeamViewer Business has positively impacted my organization by helping us resolve critical issues within the four-hour SLA contracts we have with clients, avoiding penalties associated with delays."
"I have been satisfied with TeamViewer overall."
 

Cons

"I have faced stability issues with Microsoft Intune plenty of times, but I think it's part of the process."
"A new Intune feature allows application packaging, but it incurs additional licensing costs for a significant number of applications."
"A feature I would want to see added in Microsoft Intune is the ability to manage other non-Microsoft devices."
"Some enrollment features could be improved."
"Lacking ability to leverage more iOS device management internally."
"I heard some pain points. The main thing is the learning curve. It took time to implement. It was not the best product starting out of the gate."
"There is room for improvement in the reporting capabilities, specifically app reporting. It is challenging to report which apps are installed on which device."
"The product needs to upgrade itself when the server is overloaded."
"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."
"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."
"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."
"I would like to be able to access and manage all brands of smartphones."
"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."
"A feature that they could add is chat with sound to talk."
"We have a consultant that helps us do the virtual aspects of TeamViewer."
"TeamViewer could improve by having a cloud version. Having the solution on the system could cause some cyber security concerns with data."
"One thing that would really help with TeamViewer Business is if they were able to provide an easier way to deploy TeamViewer Business on all devices using group policy, as the current solution is quite clunky and very technical to set up; I have struggled and spent many days trying to get TeamViewer Business pushed out via group policy, and it has never worked as we would prefer, so we end up doing it manually, which is a drain on resources."
"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."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"TeamViewer has a legacy and may not be using the latest UI trends."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
 

Pricing and Cost Advice

"The cost is handled through our Office 365 license, so I have yet to be able to compare it directly with other tools in its class."
"Intune is cost-effective as it is included in some of the Office 365 packages."
"Microsoft Intune is available for individual purchase at a low per-device cost."
"We use Defender ATP and E5 licenses."
"With one user base license, we can use Intune for up to five devices. However, with Soti MobiControl, each license is tied to a single device, meaning one license is dedicated to one device only."
"Microsoft Intune is a cost effective choice. It is less expensive than other products on the market."
"There is a license needed to use the solution and we are on an annual license."
"My team members bundled it together with their Microsoft solutions, including Microsoft 365 and related products."
"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."
"We are not using the solution for commercial use therefore it is free to use."
"We are using the free version of TeamViewer."
"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."
"The version of the solution we are using is free."
"TeamViewer has multiple licensing options."
"We have a corporate license. The maximum amount number of users changes based on the amount you pay. E.g., with our license, there is a maximum amount of users who can use the solution at the same time (10 users)."
"I used the free version of TeamViewer."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
