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.

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

"One of our clients migrated the model workplace based on Intune, achieving a 78 percent cost reduction, which is quite a lot."
"The most valuable features are the ones that make sure that the deployment is of a standard operating system and the Zero Touch deployment, which is very useful. This allows users to have an out of box experience."
"What I like most about the tool is that it's now very easy to set up a device for someone to use. It also helps us tremendously in managing security. Before, we used on-premise management with a domain controller. It was difficult to manage security comprehensively. For example, it was hard to know which computers were updated. We weren't able to do that easily with our previous solution."
"Intune can wipe devices. For example, if a disgruntled employee wants to leak the data on their company phone, Intune can terminate their access and wipe the entire device with a click."
"When a user receives the machine, sets it up, and turns it on, it connects to the domain and begins installing software, becoming ready within approximately half an hour, which represents a significant time savings for IT departments."
"The ability to push applications on devices is valuable. You do not have to manually install applications one by one. If you like to use ten different applications, you do not have to manually go and download them one by one. Intune can compile a package for you, and then you can just push them from the admin center."
"The automatic patch management feature in the Intune Suite is helpful."
"Based on my experience, I would recommend Microsoft Intune to organizations looking for management of a large number of devices and enterprise environments."
"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."
"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."
"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."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"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."
"The most valuable feature has been the ability to give control to others for support purposes."
"The dashboards they have are good."
"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."
"It is quite simple to set up."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
 

Cons

"It's only good for a Microsoft environment."
"In future releases, I would like to see better integration with Apple products."
"Microsoft Copilot in Microsoft Intune is absolutely useless for protecting my environment."
"Microsoft Intune's app deployment presents challenges for non-MSI and non-store apps, particularly EXEs, requiring the use of a Win32 wrapper tool and adding overhead to the process."
"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."
"My whole team is saying that they would rate technical support a three or four out of ten."
"They need to add more group policies. Intune currently does not have many group policies that you can deploy. Its reporting, which is very limited at the moment, also needs improvement. It will be great if they can add report customization. Its stability needs to be improved. Sometimes, when you register a device in Intune, it doesn't show up instantly on the engine portal on the admin side. They need to provide better support for complicated issues. They also have a long turnaround time."
"However, due to access limitations, we are unable to deploy certain security features on end-user devices."
"There could be a section in the menu describing the new features and changes."
"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."
"I would like to be able to access and manage all brands of smartphones."
"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."
"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."
"They need to better advertise the features."
"TeamViewer could be more secure."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"Voice communication and screen communication or face-to-face communication could be improved."
"The business interface is clunky and not well-documented."
"The solution could have better scalability."
"The product's expensive nature is an area of concern where improvements are required."
"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..."
"I believe latency can be optimized, and security control sometimes goes over the top and feels excessive."
 

Pricing and Cost Advice

"Cost is not my department, but the product is included in the E5 license that we already pay for every user, so no additional cost is incurred."
"They have categorized the licenses according to the size of the business. So, if it's a smaller organization, we can choose the license accordingly. If it's a big organization, then we can choose accordingly. Everything is clearly mentioned, and we can decide. It's suitable for all kinds of infrastructure, and that's very goo"
"Microsoft's licensing is more flexible and adaptive than its competitors."
"It is cheap, but as compared to Google, it is costly. Google is cheaper, but quality-wise, Microsoft Intune is better."
"The product is relatively pricey, but considering its benefits, I'd say it's fair. The benefits outweigh the expensive licensing fees, especially for large organizations, but medium-sized and smaller businesses may be unable to afford it."
"We work in the charity sector, so a lot of our clients get Microsoft Premium licenses or Business Premium for free. They get ten licenses free, and a lot of our clients do not have more than ten staff members. They are getting the tool for free, so its cost is not an issue."
"It's reasonable. They're not giving it away, but it's reasonable."
"The pricing needs improvement."
"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 is very pricey. You have to sign up for a yearly subscription."
"We use the free version of TeamViewer."
"We have a corporate license. The maximum amount number of users changes based on the amount you pay. E.g., with our license, there is a maximum amount of users who can use the solution at the same time (10 users)."
"It would be nice if it is cheaper."
"The price of the license could be less expensive."
"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."
"We have a permanent license and the price is reasonable."
