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 most valuable feature of Microsoft Intune is having all our devices compliant with our policies."
"The most valuable feature of Intune is the user-friendly portal for end users."
"With these improvements, I estimate we've reduced our patching costs by over $100,000 a month, as the MSP previously had to troubleshoot various issues manually."
"The most valuable feature of Microsoft Intune is that it is more of a one-stop shop, providing an easier experience."
"What I appreciate the most about Microsoft Intune is that it's quick and easy to use from an authenticator perspective. There is simplicity in securing our platform. Microsoft Intune benefits my company because of its simplicity of use and cross-functional integration."
"The ability to manage devices over the cloud is a big benefit, as devices now receive updates regardless of location."
"For our clients, the conditional access feature along with different compliance policies that they can set is valuable."
"It has improve our organization through the remote management of non-domain joined devices."
"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 most valuable feature is safety."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Setting up the solution is easy and there's no maintenance involved."
"We can also monitor our systems at any time from practically anywhere."
"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 is quite simple to set up."
"TeamViewer Business has positively impacted our organization by reducing the time of the TAT for resolving issues for end users, which has really helped us."
"There have been a couple of times with the handy remote access feature, where I have been asked for something at eight o'clock on a Thursday evening and it is on my desk machine, but I am driving back to my office. With TeamViewer, I can just stay at my home machine, connect to my work machine, and get the data needed without having to drive back across town."
"The most valuable features of I use TeamViewer are the ease of access and frequent updates."
"Getting started with TeamViewer was easy, with a very straightforward usage"
"TeamViewer allows us to do multiple controllers on a Host, which is great. We have a lot of Macs in our organization, and TeamViewer being cross-platform is a good thing."
"This solution is straightforward to use."
"The pilot feature is what stands out the most. I love the ability to use the pilot feature for remote inspections. The augmented portion of the software comes in handy when I have to assist my inspectors. They use the app in the field, and they show me what they're seeing through their phones."
 

Cons

"The current Intune reporting functionality could benefit from some improvements."
"Microsoft Intune lags market leaders, such as Apperian, in its MAM capabilities."
"Microsoft Intune is not user-friendly to manage and has room for improvement."
"China blocks Google and Google Play Store, which makes installation challenging. Microsoft Intune is a company software, which has to be installed to the app portal or Microsoft Software Center."
"The configuration and pricing can be improved."
"My main pain point for Microsoft Intune is the contact part. Not all Android or iOS applications have access to integration, for example, contacts."
"Onboarding of endpoint devices is not straightforward. The onboarding process was a little heavier than I thought it would be. That's the key improvement area. Obviously, the more control you have over the devices, the better it is."
"I would like Intune to natively support easier report generation. This improvement would enable less experienced staff to run reports more efficiently without relying on additional tools or functions."
"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."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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."
"There could be a section in the menu describing the new features and changes."
"I would like to be able to access and manage all brands of smartphones."
"The business interface is clunky and not well-documented."
"On occasion, when remote connection process can't connect to a machine, the error messages aren't always helpful to tell you why you can't connect, as the message doesn't help troubleshoot whether it is too slow, too much interference, etc. I usually have to run to another computer and figure out what is going on, then restart it. The diagnostics could be improved."
"TeamViewer could improve by having support for other operating systems, such as Linux."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"I didn't like the fact that you had to install a client for remote support. If you didn't install the client, you were very limited in terms of what you could do. For a whole enterprise, it is just not an easy task to install a client on everything. Even if you're using SCCM, it is an undertaking. For transient clients that you don't necessarily support a hundred percent of the time, it would be nice to be able to connect to them and support their issues without having to install something on their machines. In my previous company, we were looking at this solution as being a collaborative tool for the enterprise in terms of video conferencing, calling, and scheduling. They were working on bringing a bunch of products together to make their suite a little more integrated, but it really wasn't at the point where we wanted it to be in terms of integration. We looked at it, reviewed it, and tested it out a bit. We then decided to go with Microsoft Teams. It has the clunkiness of having separate modules that aren't totally integrated. There are different methods for doing different things, which makes it a little bit more complicated. There should be the same way whether you are doing remote support or just calls."
"Sometimes we'll have a device in the field, and I'll click on remote control and it says "Can't authenticate." I'll double click in a different part of the TeamViewer interface and it'll say "Can't authenticate." Then I'll do it a third time and it connects. It's possible that it's just bad luck. It's also very possible that it's some bug within TeamViewer..."
"Sometimes it gives problems, with the button not working, and I was unable to log in."
"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."
 

Pricing and Cost Advice

"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 expensive. The cost depends on the license that we choose."
"We have the business premium licenses for the solution."
"The pricing is not cheap, especially with inflation. They've had to increase their prices. It's not excessive, but alright."
"It's affordable. It's cheaper if you have an Office 365, E5, or E3 subscription because everything is there."
"There is a cost benefit of using Microsoft Intune because of the packaging with other Microsoft products."
"Intune is included in the Microsoft 365 licensing package that we have."
"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 solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"The price was cheaper than what we were previously paying. At the time that we went with TeamViewer, we were using ShareConnect. The TeamViewer package was about half the cost and able to have a bigger number of users."
"I used the free version of TeamViewer."
"The cost is in the thousands of dollars per year."
"We have a permanent license and the price is reasonable."
"We use the free version of TeamViewer."
"We are using the free version of TeamViewer."
"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."
