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

"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."
"My favorite feature about Microsoft Intune is that I have good logging capabilities; I can effectively troubleshoot, though I'm also missing some aspects."
"The most valuable feature is the policy CSPs."
"At the moment, Autopilot is the most valuable feature."
"Intune can wipe devices. For example, if a disgruntled employee wants to leak the data on their company phone, Intune can terminate their access and wipe the entire device with a click."
"Microsoft Intune has definitely reduced management burdens."
"It is a very helpful solution."
"The thing I appreciate most about Microsoft Intune is that the management of the devices was very simplified. We have all machines connected to it at all times, whether they are in the office or working from home."
"The most valuable feature is safety."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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."
"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."
"Setting up the solution is easy and there's no maintenance involved."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"TeamViewer is a scalable solution."
"The most valuable feature of the solution is that it is very fast. The file transfer from remote machines to my machine or from my machine to the remote machine works well."
"With an image, you can see immediately what's going on. You can run some tests. Without the solution, you need to do everything by telephone. It's not even thinkable."
"It's a user-friendly product."
"The document control is quite good."
"TeamViewer has a good interface."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
"TeamViewer is useful for accessing data and systems remotely. Using this application, I can access other computers using an ID number that I provide to the users whose laptop I would like to access."
 

Cons

"They should make it easier to order it, however, that's generally true for everything from Microsoft."
"Microsoft Intune is not user-friendly to manage and has room for improvement."
"From a new user's perspective, it may be a little overwhelming because there are quite a few things to look at in the console, however, once you are sort of acclimated and are familiar with your core functions, it's fairly simple and straightforward."
"The interface is easy, but it is not user-friendly when evaluating the overall user experience of Microsoft Intune."
"Intune's privilege management feature, while beneficial, is less intuitive than other Intune features, making it challenging to use."
"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."
"Due to the abundance of features, there's a lot to organize, which makes managing and setting up the solution challenging. The setup is immense, and it would be good to see improvement in this area."
"Lacking ability to leverage more iOS device management internally."
"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 have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"There could be a section in the menu describing the new features and changes."
"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."
"I would like to be able to access and manage all brands of smartphones."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"The solution could improve by increasing or removing the time limitation on the use of a session."
"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."
"Considering the earlier versions of the product, I think TeamViewer used to slow down the systems."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"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."
"Every now and then you'll get a silent crash and you relaunch the application. But it happens no more than with anything else in the Windows environment."
"TeamViewer could be more secure."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
 

Pricing and Cost Advice

"I recently got to know that the AD P1 license is compulsory to use Intune Autopilot, which was surprising for me. Earlier, this was not the case. It is the wrong thing to do. We now need to purchase AD P1 licenses for us and for our customers. I would rate it a seven out of ten for pricing."
"The purchase of the product was handled by someone else."
"No one can compete with Microsoft when it comes to price, and the features it is offering."
"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."
"Licensing depends on how you are providing support to your enterprise, whether it's device-based or user-based."
"In terms of the product price and licensing costs, my company finds the product to be reasonably priced."
"Intune is available as an individual product, but it also comes with Office 365 Premium or an Enterprise license, and the price varies for each version."
"We don't get Intune as a separate module. Most of the time, we use it within an enterprise agreement like E3 or E5. Those licenses are at a good price, but what is annoying is that every single year they go higher."
"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."
"The solution's pricing is reasonable."
"It does what I need it to do but I think it's expensive. It wasn't easy for me to get approval from the company to get it... It's costing us about $700 a year, per license."
"TeamViewer has multiple licensing options."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"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 pricing is reasonable... The simultaneous controller licensing model of TeamViewer - compared to LogMeIn’s controlled Host licensing model - seems to benefit us so far. We’re currently saving about 30 percent on licensing cost... The savings from licensing have been eaten up by the soft costs involved in dealing with and working around TeamViewer’s deficiencies in allowing granular control by multiple controllers, and the issues with the various settings that are missing on the macOS Host."
"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."
"TeamViewer is $600 or $700 per port per year..."
