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 improved productivity and saves onsite visits through fast issue resolution
TeamViewer Business provides a fast and secure connection along with a reliable chat feature for a smooth support section. I also appreciate the monitoring and asset management capability, which enhances the remote access experience for my team and me. TeamViewer Business provides seamless communication capability, which includes a variety of options such as chat, call, and video that enhance interaction with our remote clients. TeamViewer Business has been really helpful in my organization, where we are able to troubleshoot any issue our clients have and resolve it as quickly as possible. It enables me to fix the problem faster. If a customer's screen is not working or a glitch happens, I can simply share their screen into my screen through TeamViewer Business and rectify the issue rather than asking them to describe the problem via email. This saves a lot of time and is helpful for our customers who are buying our products. The best features TeamViewer Business offers include seamless communication, efficient remote access, and fast and secure connection.

Quotes from Members

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

Pros

"Microsoft Endpoint Manager is not expensive overall, especially for small environments."
"The user experience of Microsoft Intune is very friendly and the interface is very good."
"Remote Wipe and Autopilot is one of the best features."
"The stability of Microsoft Intune is ten out of ten."
"I mainly use Microsoft Intune analytics for taking that data that exists and bringing it into Power BI dashboards to make it visible to our clients, showing them all the operating systems in their environment and where the latest patches are, and then from there creating plans."
"Its security is most valuable. It gives us a way to secure devices, not only those that are steady. We do have a few tablets and other devices, and it is a way for us to secure these devices and manage them. We know they're out there and what's their status. We can manage their life cycle and verify that they're updated properly."
"Intune significantly simplifies application deployment, mobile application management, and policy enforcement, such as restricting user access to specific applications, thereby enhancing overall environment security."
"One of the most valuable features of Microsoft Intune is the detection and remediation script capability."
"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."
"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."
"The most valuable feature is safety."
"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."
"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 quality of the call and the quality of the sharing have been excellent."
"The product and platform work well. That is why I have stay with them so long. The stability has typically been good."
"It's a user-friendly product."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"Using TeamViewer for my personal clients has made things much better for me and my clients because my clients are happy to resolve a problem within seconds via TeamViewer."
"TeamViewer has been one of the easiest, right off the bat products, that we have employed at the college. We have had no issues. It's been one of the easiest solutions to pick up."
"TeamViewer is a step ahead of solutions like, for example, AnyDesk."
"The most valuable feature of TeamViewer is its ease of use."
 

Cons

"It would be interesting to integrate the server side of Intune. Some group policy updates we have on the Windows Server side and possibly some on the client side could also be included."
"Intune doesn't provide much control over Windows servers. It's something we struggle with."
"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."
"In terms of the admin experience, it is straightforward, but the Windows enrollment experience could be improved. Sometimes, for enrollment, we have to reset devices and re-enroll them."
"One issue that Inutune can improve is password integration with the BitLocker key option. Another issue is assigning licenses. We can assign the licenses for some users on the BPM side, and our BPS users work on Outlook 365 but cannot access it there. A BPS person can go to the company portal and download Outlook 2016. They could improve the NDIS part to assign a license directly to the BPS person that allows them to install the Intune device manager directly on our system."
"The solution could improve by having better integration with Apple."
"If you wish to block any App Store application, there is no way to do so."
"I rate Microsoft customer service six out of 10. While some technicians go above and beyond, there is inconsistency, and connecting with the most helpful representatives is occasionally challenging."
"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."
"I would like to be able to access and manage all brands of smartphones."
"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 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."
"It would be helpful if they had iSupport for supporting Apple phones."
"There could be a section in the menu describing the new features and changes."
"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."
"The installation and the update agent could improve."
"TeamViewer could improve by having a cloud version. Having the solution on the system could cause some cyber security concerns with data."
"TeamViewer could improve by having support for other operating systems, such as Linux."
"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."
"The support could improve their speed."
"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."
"The solution could have better scalability."
 

Pricing and Cost Advice

"The pricing needs improvement."
"I am satisfied with the pricing."
"While I don't have access to high-level financial information, I believe we have achieved lower costs with this implementation."
"Intune is cost-effective as it is included in some of the Office 365 packages."
"Microsoft Intune is a cost effective choice. It is less expensive than other products on the market."
"The price is reasonable, but they should lower it a bit to make it more competitive. It's cheaper than AirWatch and other products, but I still feel like Microsoft can make a base version or with Exchange online or a la carte only Intune version which will be useful. A customer who doesn't want to go full-fledged E3 or E5 can take out or consume an Intune solution only for their purpose, and we want to target that customer."
"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."
"Existing E5 license holders for M365, Intune, and Azure, receive a free license."
"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 are using the free version of TeamViewer."
"There is a free and paid version of this solution. I am currently using the free version."
"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."
"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."
"We are using the free version of TeamViewer."
"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."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
