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

"While I don't think you can ever have full visibility and control, Intune certainly allows us to see the applications being used and tells us if things like Windows patches aren't applied to machines. It does a good job. That visibility makes life a little easier."
"I have seen a return on investment right from the start of the tool's usage."
"For our office workers who are not based in Norway, when we order the PC, we can do some of the settings for them. These are standardized settings. We can set them up exactly as they are in Norway so that they're the same."
"It is a very stable and scalable cloud-only solution."
"It provides control over all mobile devices that are being connected to the corporate network."
"Stable product that's easy to set up compared to other MDM products."
"The most valuable feature is probably mobile device management. Small businesses are coming under greater scrutiny and requirements for compliance as time goes on. We don't have to worry about a VPN because we can manage these devices, control company data, and lock users out. If needed, we can remotely wipe devices and deadman-switch them."
"Overall, I like Intune as a solution and would rate it nine out of ten."
"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."
"We can also monitor our systems at any time from practically anywhere."
"I personally really appreciate the file transfer feature as it is really easy to use."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"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."
"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 features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"The product is quite stable. The performance is good."
"Our computers are spread amongst six physical locations. TeamViewer reduces the need to travel to those offices to help staff."
"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."
"This solution is straightforward to use."
"Getting started with TeamViewer was easy, with a very straightforward usage"
"The dashboards they have are good."
"From my perspective, the most important is the login."
 

Cons

"What frustrates me the most is just waiting and tapping my fingers, uncertain about whether my changes will take effect."
"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 see Intune improve its handling of hybrid domain joins."
"I think there should be a better tracking of the cell phones used on the Intune."
"Onboarding of endpoint devices is not straightforward. The onboarding process was a little heavier than I thought it would be. That's the key improvement area. Obviously, the more control you have over the devices, the better it is."
"The reporting needs to be a bit more interactive."
"It would be helpful if there was proactive remediation."
"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."
"There could be a section in the menu describing the new features and changes."
"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 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."
"It would be helpful if they had iSupport for supporting Apple phones."
"They need to better advertise the features."
"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 see something like a TeamViewer mobile application for iOS or possibly Android. I think this would be fantastic given how technology is evolving today. It would be beneficial to use it with your smartphone."
"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."
"The solution could be improved by enhancing the use of the mobile version to be used on phones."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"TeamViewer has a legacy and may not be using the latest UI trends."
"I would like to see TeamViewer support multiple platforms."
"The file transfer functionality crashes sometimes."
"TeamViewer could improve by having a cloud version. Having the solution on the system could cause some cyber security concerns with data."
 

Pricing and Cost Advice

"Intune is included with our F3 and E5 licenses."
"The overall pricing of Microsoft Intune is good for companies that have big IT budgets, 3,000 or more users and devices."
"The price of Intune is often included as part of a bundle with other Microsoft licenses, which makes it somewhat cheaper."
"It is expensive. The cost depends on the license that we choose."
"Any bundle package, such as Security E3, covers multiple things, such as AAP, BitLocker, etc. If you go for them individually, they would be more expensive. Bundling makes the price more attractive and competitive."
"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."
"For organizations that are a Microsoft shop, the pricing is compelling."
"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."
"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."
"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."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"I used the free version of TeamViewer."
"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 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 would be nice if it is cheaper."
"We are using the standard free version of TeamViewer."
"TeamViewer is $600 or $700 per port per year..."
