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

"The best features include the management, which is quite good, and endpoints."
"The initial setup is not overly complex or difficult."
"The most valuable feature of Intune is the ability to reset a lost device and remove all the data."
"The most valuable feature is that we can manage workstations or Android devices remotely without needing the device to be connected to our local network."
"The user experience of Microsoft Intune is quite good because there's not much disturbance in the background; it's just running in the background."
"At the moment, Autopilot is the most valuable feature."
"...Intune itself integrates with that entire Microsoft ecosystem. As an individual product itself, it's okay. It holds up. But when you start saying "I've bought this as part of a wider solution, as a company we are going Microsoft throughout," then it makes more sense to have Microsoft Intune... so you have that single dashboard."
"The most valuable feature is that we can manage workstations or Android devices remotely without needing the device to be connected to our local network."
"I personally really appreciate the file transfer feature as it is really easy to use."
"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"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."
"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."
"The most valuable feature is safety."
"TeamViewer is stable."
"It's very easy to set up."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
"The most valuable feature of TeamViewer is its ease of use and beneficial remote access."
"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."
"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."
"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 saves trips to customer sites, which saves time. I am able to get in there remotely and fix things."
 

Cons

"We had an APNS certificate set to expire last week. We tried to renew it two days before it expired. We logged in to the APNS portal but could not find that certificate. We didn't know where it went. All the iOS devices stopped working. We contacted the Apple and Microsoft teams, and each blamed the other. This is something that Microsoft should take care of. Last week, we had so many escalations from high-profile users who couldn't access corporate data on their devices."
"Microsoft Intune lacks the ability to provide seamless remote assistance or remote control."
"An area for improvement is the absence of seamless integration, particularly with external dashboards."
"Microsoft Intune is currently overpriced."
"When we implemented Intune, it would have been helpful if Microsoft had provided some videos or data about Intune."
"There are a lot of small use cases where we realized that some technical solution was missing in Microsoft in comparison to other products. For example, it lacks something similar to sensing or location-based rules and configurations."
"Intune should support platforms other than Windows. We have encountered several limitations, especially when handling iOS devices."
"In the next release, I would like a feature to be able to properly lock down the device. For example, if an attacker or somebody steals the phone, you can be sure that the pin cannot be broken."
"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."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"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 could be a section in the menu describing the new features and changes."
"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."
"We access the solution through a VPN, which improves our security. However, earlier this year, around the beginning of March, a CVE in the TeamViewer client allowed remote connections to other network systems, which was concerning. You could have unintentionally gained admin rights if you didn't update TeamViewer promptly. It's crucial to always keep it updated to prevent such issues. The tool should consider implementing two-factor authentication to improve such security holes. It should also integrate good security updates, which should be implemented automatically."
"I have noticed that when I access another person's computer, sometimes the tab is visible, and sometimes it is not, which can be difficult."
"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 business interface is clunky and not well-documented."
"The installation and the update agent could improve."
"We'd like to be able to work from mobile to desktop and vice versa. We'd like more mobility."
"This solution could be improved by offering more flexibility in terms of usage."
 

Pricing and Cost Advice

"Microsoft Intune is available for individual purchase at a low per-device cost."
"The price for Intune is fair."
"While I can't provide insights from a business perspective, it's worth noting that the pricing may differ significantly, and the discount we received might not be reflective of standard business rates."
"It comes as a bundle, so you do not really know what the prices are. Microsoft does not break it down to the user cost for us. It is just bundled with our E5 license."
"Microsoft Intune is a cost effective choice. It is less expensive than other products on the market."
"Licensing depends on how you are providing support to your enterprise, whether it's device-based or user-based."
"Intune is moderately expensive. You can get the license bundled with Office 365 E3 or E5 licenses. The E5s are a bit expensive, but you get some cheaper solutions with Intune."
"All security solutions worldwide are expensive. Microsoft has allowed a small scale of features within Microsoft Intune for cost-efficient solutions. If you want the full suite, you need to invest more to gain better security features."
"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."
"The cost is in the thousands of dollars per year."
"We are using the free version of 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."
"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."
"TeamViewer has multiple licensing options."
"The version of the solution we are using is free."
