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 is absolutely a positive investment."
"The ability to wipe data from and reset devices is one of the most important and valuable features. If a device is reported stolen, we can freeze it or wipe the data from it, preventing data leakage."
"Dynamic groups allow us to set conditions for automatic membership, eliminating the need for user intervention or manual review and ensuring a seamless workflow."
"Microsoft Intune is a cost-saving solution, reducing IT department workload and allowing for faster device provisioning compared to traditional methods."
"Intune provides full endpoint visibility and IT control across device platforms. You can individualize it for your company with the Intune Company Portal app."
"At the moment, Autopilot is the most valuable feature."
"My favorite feature of Microsoft Intune is the dashboard; the dashboard is very simple and user-friendly, and any person, even without prior knowledge, can understand it easily by seeing the interface dashboard."
"In terms of technical support, you will get an immediate response."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"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."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"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."
"TeamViewer has a good interface."
"The most valuable feature of TeamViewer is user-friendliness."
"It was worth the investment. You can do file transfers and video calls with it. You can do a lot of copy paste stuff. E.g., if I have a file and want to place it on somebody's machine, I can just copy it off of mine and paste it right on their machine. I don't have to put it in a Dropbox account and have them log into it to pull it off. I can do all that right through TeamViewer. When you're looking at the TeamViewer screen, you think you are working on your own machine."
"TeamViewer Business has positively impacted my organization by boosting efficiency since you do not need to be physically available to the client to troubleshoot or help them."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"The most valuable feature of TeamViewer is the remote access connection. Additionally, it is easy to use."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
 

Cons

"Every time we call, we get bounced to a new team... there is no cohesive end-to-end support, which is very frustrating and time-consuming."
"The mobile management is good for iPhone and iPad, but the Apple Mac management needs improvement. That is probably because Microsoft does not have low-level access to Apple Mac hardware. If you are doing basic things, it is okay, but if you want to image Apple Macs and do things like that, then Jamf is much better."
"Intune doesn't provide much control over Windows servers. It's something we struggle with."
"There are a couple of issues with stability."
"I have experienced downtime, bugs, and glitches. I rate it a seven because when we have bugs or instability in Microsoft Intune, we need to wait for the backend from Microsoft Intune to resolve issues and we can't deliver solutions to clients because we need to wait for action plans and related processes."
"We are currently unable to control aspects of group policy from Teams like we can for GPO. They are still not part of Intune. Microsoft is adding this, but it's currently in preview, and few GPO features have been added to the product."
"I switched away from Microsoft Intune because it cannot manage the MacBook very well."
"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."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"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."
"TeamViewer could be more secure."
"The installation and the update agent could improve."
"I'm not sure if they provide good quality audio alongside screensharing."
"TeamViewer is publicly available and anyone can use it. This is the reason that many organizations do not permit the use of this solution. It is not considered to be secure enough."
"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."
"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."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"This solution could be improved by offering more flexibility in terms of usage."
 

Pricing and Cost Advice

"Microsoft Intune is not cost-effective as a standalone product."
"The overall pricing of Microsoft Intune is good for companies that have big IT budgets, 3,000 or more users and devices."
"The cost of the license and the features are justified for myself as a technical person."
"I rate Intune five out of 10 for pricing. It's expensive."
"The Intune license model is costly."
"It is average. Some of the costs are quite high depending on what the customer currently uses, but overall, it is not bad. I would not say that I would not recommend Intune based on the cost. I definitely would, but they can definitely improve on the cost. So overall, its cost is not bad."
"In terms of the product price and licensing costs, my company finds the product to be reasonably priced."
"The price for Intune is fair."
"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."
"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."
"TeamViewer is $600 or $700 per port per year..."
"TeamViewer has multiple licensing options."
"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're using the free version. We do not pay any licensing fees."
"It would be nice if it is cheaper."
"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."
