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

"The navigation, the keys, and the settings are easy to find. It is easy to understand."
"It's really easy to access."
"The solution is easy to use and it has good performance."
"My favorite feature about Microsoft Intune is that I have good logging capabilities; I can effectively troubleshoot, though I'm also missing some aspects."
"The biggest thing for us is enforcing logins only from devices that are managed by Intune."
"I would rate the overall solution as a 10."
"The solution is easy to use."
"It provides control over all mobile devices that are being connected to the corporate network."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"We can also monitor our systems at any time from practically anywhere."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"I personally really appreciate the file transfer feature as it is really easy to use."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"Setting up the solution is easy and there's no maintenance involved."
"The most valuable feature is safety."
"It's very beneficial and time effective on how we are able to provide quick support. We've quadrupled our effectiveness as an IT support because we have cut down all that unnecessary travel time, even between floors."
"The most valuable feature of TeamViewer is its ease of use."
"It is a scalable product."
"The TeamViewer system has some built-in security. The TeamViewer client connects to the TeamViewer host securely. Only a certain number of authorized users on our side have access to the system. Even within that, an individual endpoint can be assigned to a group, where not everybody has access but, rather, just one or two people who are part of a support team might have access to that particular device. So TeamViewer has given us tools to be able to segregate who has access to different things."
"With an image, you can see immediately what's going on. You can run some tests. Without the solution, you need to do everything by telephone. It's not even thinkable."
"TeamViewer Business has positively impacted my organization by helping us resolve critical issues within the four-hour SLA contracts we have with clients, avoiding penalties associated with delays."
"TeamViewer is fast and easy to manipulate."
"The product and platform work well. That is why I have stay with them so long. The stability has typically been good."
 

Cons

"The difficulty of the the roll out is surprisingly difficult considering this product is supposed to be an integrated part of the 365 suite."
"I would like more clarity on how Intune is migrating control from Active Directory group policies, especially as we move over to Windows 11. It seems inefficient to manage some settings in Active Directory and others in Intune."
"What I dislike about Microsoft Intune is the time it takes Microsoft to develop a feature."
"There are some issues using the solution with macOS and iOS, and it offers limited granular control with them. Intune works better on Windows and Android."
"While the ability to deploy applications at startup is reliable, the policy-based application deployment method has not reached the same level of consistency."
"The backend of Microsoft Intune needs to be improved. We have seen a little bit of delay as compared to other MDM solutions. That needs to be improved. A little bit more granularity should also be added"
"I have a lot of Apple products in my environment. It would be nice to have an improved integration of Apple products with Microsoft Intune without Jam."
"The installation is very easy. However, to be able to configure it you will need special knowledge, such as training or self-studies to have a proper level of security. There are many settings one has to understand before being able to implement Microsoft Intune."
"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."
"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."
"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."
"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."
"This solution could be improved by offering more flexibility in terms of usage."
"The performance could always be better."
"I would like it if the trial version of TeamViewer allowed you to have a connection for much longer."
"It would be beneficial to have group functionalities to separate access when many consultants want to access different departments or clients at the same time."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"TeamViewer could work on performance latency in slower internet connections by optimizing screen refresh rates during remote sessions, especially when transferring large files or using graphics-heavy applications."
"In the next release, I would prefer to have a voice integration and collaboration feature to support multiple teams simultaneously."
"The installation and the update agent could improve."
 

Pricing and Cost Advice

"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."
"The pricing is good because customers are not complaining about it."
"The price of Intune is included with the license for Office 365, so we don't have to pay anything extra for it."
"We work with the subscription rather than a server license. I think it's economical this way because we don't have to have a server license for that, and I think that works in our favor."
"Microsoft Intune is more expensive than other solutions, but it offers a wider range of features and control."
"Previously the price was $4 per month per user. Now it's $2.25 per user per month."
"Microsoft offers some licensing where it's included at no extra cost when customers are already using the licenses. In such a case, it's a really good value. If you have to buy the licensing for it, it's probably on par with other solutions. It isn't substantially more or less expensive. The great thing is that it is included in some of Microsoft's licensed packages. So, some customers don't have to spend additional money for it. Typically, most providers that support Intune do charge a management fee of some sort or some fee. Certainly, we're no exception."
"The pricing for Microsoft Intune is reasonable. Our clients are satisfied."
"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."
"TeamViewer offers a free version to try. Download and give it a shot. See what it's like and if you like it, then buy the license for it."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"The solution's pricing is reasonable."
"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."
"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."
"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."
"There is no license needed to use TeamViewer."
