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.
Begaya Morris - PeerSpot reviewer
Lead Software Engineer at BD
Reliable remote access has improved secure collaboration and streamlined daily approvals
The best features TeamViewer Business offers in my opinion are collaboration, templates, a high level of security, and session recording. Collaboration allows me to collaborate remotely with my team members. Besides reconnecting automatically, it provides a high level of security, protecting from cyber attacks and aids in providing assurance in regulated environments through two-factor authentication and end-to-end encryption features. It also allows recording live sessions, which can be replayed as needed for future reference. TeamViewer Business has positively impacted my organization as collaboration has enhanced, especially remote collaboration by 60 to 70 percent. I have been able to collaborate with clients and other team members seamlessly. Enhanced workflow efficiency includes faster approvals and a lowered risk of data loss, misuse, and leak through robust features like two-factor authentication and end-to-end encryption. It also facilitates compliance using documentation and auditing through recordings and logs.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Based on my experience, I find Intune very flexible for managing Windows devices. We can use scripting, and we can make use of the self-service portal or the company portal to publish some of the applications for Windows."
"Intune's most valuable feature is its centralized management capability."
"With on-premises Active Directory, the main challenge was that we had no control when a user was working from home. We didn't know what exactly a user was doing and whether the AV was up to date or not. Intune provides better control of their machines."
"Agile and easy to deploy MDM solution that covers the maximum number of policies. Stable, scalable, and with knowledgeable technical support."
"The best features in Microsoft Intune that I appreciate most are its centralized features."
"Microsoft Intune is easy to use, and it is able to enforce policies towards multiple devices. It is able to bring multiple classes of devices into the same security posture. I found that very useful."
"Intune's security features for Apple iOS and Mac OS are helpful. We can check enrollment, manage public and private settings, and manage the organization's data using security key features."
"The core management feature in Intune is invaluable to us, especially considering the challenges we often face with System Center when pushing external updates."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"We can also monitor our systems at any time from practically anywhere."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"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 solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"The most valuable feature is safety."
"I find the mouse control and the ability to click for them very effective. I can move the mouse and click on buttons as if sitting at their computer. These are the basic features I use most often in the solution. There are tricker features that I don't use much because I don't need them frequently. Overall, it's a great tool for helping others with their computer issues without traveling to their location or another building."
"It saves trips to customer sites, which saves time. I am able to get in there remotely and fix things."
"The most valuable feature of TeamViewer is the ability to remote into another device."
"I have found the solution to be user-friendly even for beginners. It is not that sophisticated. There are different types of security features available, such as encryption and random machine ID."
"The quality of the call and the quality of the sharing have been excellent."
"It's very easy to set up."
"This is a unique solution that is very easy to install."
"The product is quite stable. The performance is good."
 

Cons

"Microsoft Intune could improve in reporting data for endpoints and fleets. Enhanced capabilities to run queries and gather specific device data to identify trends or issues would be beneficial. The feature parity for MacOS and handling devices from an MDM perspective is not comprehensive. Consolidation of these functionalities within Intune would simplify processes and finances."
"There are a lot of updates coming from Microsoft that suddenly affect our security policies."
"I know that their AI pieces are at the infancy stage, but allowing users to do more tagging for information would be an interesting thing because Intune also directly integrates with Azure. Because a lot of the devices are hosted with that, you also get a lot of tagging of user data and other things like that."
"For additional functionality, I suggest that Microsoft could expand on asset management. Since the platform is there, they could develop it into a full-fledged asset management system."
"There should be more focus on mobile device security and integration."
"Back in 2020, there were significant problems with report accuracy, particularly regarding web patching."
"It would be better if they can reduce the cost of the license."
"In an upcoming release, I would like to see some kind of analytics report."
"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."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"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."
"TeamViewer Business's scalability is bad because it's very expensive."
"The product's expensive nature is an area of concern where improvements are required."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"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."
"Support for mobile devices from Linux has been missing since the Native client was rolled out. This was a nice option, especially when trying to walk somebody who was struggling to understand something on their phone."
"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."
"TeamViewer could be more secure."
"The stability of TeamViewer is good, but it could be better."
 

Pricing and Cost Advice

"There are licenses required for this solution. We enable licenses on the devices we need to manage."
"The Intune license model is costly."
"It is expensive. The cost depends on the license that we choose."
"Microsoft licenses are costly."
"The product is expensive."
"I don't have any problem as far as cost is concerned. It is bundled with our license."
"I rate Intune five out of 10 for pricing. It's expensive."
"Its licensing model is not complex, but it is very expensive compared to other solutions. They can bring more models and reduce the pricing. They should allow customers to select the features they want and price it accordingly."
"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're using the free version. We do not pay any licensing fees."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through 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."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"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 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."
"I used the free version of TeamViewer."
