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.

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

"I can reach devices or computers over the internet. I don't need to worry about the network connectivity between the offices. I can manage any device. That is the most important part."
"Intune is flexible. If you want to move a device that was previously on-prem, we can bring it to the cloud and apply all the policies. This is helpful for even those organizations that were on-prem and not on the cloud. They can also come and use these features, which are pretty cool and would be handy to protect the data and manage the devices as well."
"The most valuable feature of Intune is the central dashboard for compliance and policy management."
"By using Microsoft Intune we can control which websites the users can go to and it provides a secure environment for our employees using their laptops that are having access from home. We have installed Intune to control the user's environment minimizing the chances of any hacking."
"It saves time, money, and resources; when there was a local liaison, managing everything was a significant challenge, but with Microsoft Intune, it has become much easier—around 60% to 70% easier—and in terms of reliability and ease of use, it excels."
"The stability of Microsoft Intune is ten out of ten."
"I appreciate how easy it is to deploy certificates to end users to get control over their device with Microsoft Intune; that's what Microsoft Intune is known for, and that's what we use them for."
"One of the main features of the solution is it allows the management of many devices in different ways."
"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."
"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The most valuable feature is safety."
"Setting up the solution is easy and there's no maintenance involved."
"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."
"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."
"TeamViewer is stable."
"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."
"It is easy to use and has a pretty good UI."
"Ever since we have been using TeamViewer Business, because of how quick it is to connect to a user across the globe, we have been able to close tickets rapidly."
"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."
"The usability and graphic interface stand out for me because it is very easy to understand, with upper bars, all the features, and the file transfer functionality."
"The document control is quite good."
 

Cons

"We do not utilize Microsoft customer service and technical support since it is generally a waste of time."
"Installing software in Microsoft Intune can be challenging if it is not already prepackaged."
"We faced issues with macOS support. The product should have better inventory and asset management."
"There is room for improvement in the reporting capabilities, specifically app reporting. It is challenging to report which apps are installed on which device."
"We face multiple scenarios where IT decision-makers request specific policy implementations, however, due to product limitations, we cannot fulfill these requests."
"The most significant challenge is reporting and monitoring. The reporting accuracy for deploying applications and all aspects of Intune needs to be improved."
"Policy and app deployment should be faster, as it currently takes between minutes to hours to apply, with an average of one hour."
"I want more secure, reliable, and efficient security policies."
"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 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."
"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."
"They need to better advertise the features."
"The file transfer functionality crashes sometimes."
"TeamViewer could improve by having support for other operating systems, such as Linux."
"The solution could have better scalability."
"In the next release, I would prefer to have a voice integration and collaboration feature to support multiple teams simultaneously."
"The product can sometimes crash."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"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."
"If were to I put myself in the seat of a small business owner, I would prefer TeamViewer to be more of a pay-once-and-own-it solution, rather than paying via a subscription model (although I am using the free version). Only annual subscriptions are available. It makes paying for it the first time seem a little daunting."
 

Pricing and Cost Advice

"The pricing needs improvement."
"Microsoft Intune has a user-based subscription model. You can go for a monthly or a yearly payment."
"The price is very reasonable."
"If you're ever going to buy an Office 365 environment, then pricing is reasonable given all that it does, but if you're not, then you might find the pricing expensive."
"While Microsoft charges for actual usage, it lacks discount options."
"I liked the tool's pricing until P2 came into effect. I am unsure about the current value versus the cost of the new licensing model."
"The cost is handled through our Office 365 license, so I have yet to be able to compare it directly with other tools in its class."
"Microsoft Intune is not cost-effective as a standalone product."
"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 have a permanent license and the price is reasonable."
"We're using the free version. We do not pay any licensing fees."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"We are using the free version of TeamViewer."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"TeamViewer is $600 or $700 per port per year..."
"We are not using the solution for commercial use therefore it is free to use."
"We are using the free version of TeamViewer."
