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

"Intune enables us to manage our devices from anywhere."
"We are transforming our flat network by adopting different cloud solutions, and our own applications are hosted in the cloud. Intune ensures our security throughout our entire cloud-based system, improving our security posture."
"Autopilot is a great feature. Most users are looking for a zero-touch deployment."
"Microsoft Intune has definitely reduced management burdens."
"The most valuable feature of Microsoft Intune is patching-related capabilities."
"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 technical support of Microsoft Intune is good."
"There are many features in Microsoft Intune. For personal mobile devices, MDM is what I most prefer."
"We can also monitor our systems at any time from practically anywhere."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable feature is safety."
"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."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"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."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"The implementation is quite straightforward."
"I like that it helped a lot, even with low bandwidth network connectivity. For example, while I was traveling, sometimes there were requirements for me to join a TeamViewer session and provide technical support. I was able to do that without much of an issue. It is also a secure solution."
"The document control is quite good."
"It is quite simple to set up."
"The most valuable feature of TeamViewer is its ease of use."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
 

Cons

"I switched away from Microsoft Intune because it cannot manage the MacBook very well."
"Cost is the biggest factor for us right now. Microsoft Intune and AD P1 together in a bundle is a good thing to have, but it is very costly compared to other products in the market. Otherwise, Microsoft Intune is the best."
"I would like to see the ability to deploy custom packages as a Windows 64-bit package, as opposed to the Windows 32-bit, which is the only one available now."
"I assess the stability of the product as low. I have faced downtime crashes and performance issues with Microsoft Intune."
"Reporting in Microsoft solutions is pathetic. With Intune, I'm getting a free inventory tool, but I don't get a reporting tool. When I go to Intune, I can see one machine's entire data in terms of the hardware and the software running on it, but I cannot generate a report for all the machines in the organization. The reporting is the only feature holding back the functionality that is already there."
"Intune's areas for improvement revolve around security and certificate management."
"Intune has some limitations when it comes to application updates for third-party applications. You can schedule an update, but when it's a package setup, you need to supercede and replace it each time."
"Sometimes, the process is unsuccessful when we attempt to reset a device and wipe the data using Intune."
"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."
"There could be a section in the menu describing the new features and changes."
"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."
"I would like to be able to access and manage all brands of smartphones."
"They need to better advertise the features."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"It's not the program itself that's an issue, but there is a need for some better documentation on how to use the web portal Management Console. That seems to be a bit lacking in directions, if you aren't paying attention and you don't know what to do. Better documentation would make it a little bit easier to set things up in different groups and share groups between people."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"It should have ability to display notes in the computer list."
"Sometimes, the app can be a little cumbersome when accessing certain aspects of the program."
"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."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"It needs to have proper authentication. I would like to see in-depth integration with Google and Microsoft products, for example. It would be nice to have a cell phone version as well."
 

Pricing and Cost Advice

"Its price is in the medium range. It is acceptable because you're paying for the features. I am not aware of any additional costs."
"Microsoft licenses are costly."
"There is a cost benefit of using Microsoft Intune because of the packaging with other Microsoft products."
"The cost is somewhat on the higher side, particularly when considering certain price points, especially in markets like India."
"It's reasonable. They're not giving it away, but it's reasonable."
"Intune's pricing is reasonable considering its benefits and the high costs it helps avoid."
"Microsoft Intune is a cost effective choice. It is less expensive than other products on the market."
"I rate Intune five out of 10 for pricing. It's expensive."
"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 cost is in the thousands of dollars per year."
"TeamViewer has multiple licensing options."
"We are using the standard 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."
"We have a permanent license and the price is reasonable."
"We use the free version of TeamViewer."
"I used the free version of TeamViewer."
"TeamViewer is $600 or $700 per port per year..."
