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 transformed my work and now saves time with fast, secure file transfers
What I appreciate about TeamViewer Business is the reliable and secure connection experienced during file transfers or troubleshooting processes, even when we have to restart the PC; we are still able to connect to the customer quickly. TeamViewer Business offers a free version for both personal and business use. The free version actually covers all the features needed for secure remote connection, which is one of the positive aspects I have experienced. The secure connections and great file transfer feature are super fast and secure, with reliable features during the process of reconnecting and connecting back to clients. Back in 2009 and 2007, the internet did not have the faster features it has today. TeamViewer Business's file transfer feature has made things easier. Instead of downloading a file from a source like HP.com, we just have to transfer the file from our system to the customer securely and quickly. Many technical support people have benefited from that feature, which I find very reliable.

Quotes from Members

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

Pros

"The security posture is very good. It's very customizable."
"Using Azure and Intune has helped us resolve most of these issues, as we no longer need a physical infrastructure to manage systems and can push policies remotely while maintaining control over the devices."
"EAM is a godsend."
"I would recommend Microsoft Intune to others; it is a very good and scalable solution."
"Its direct integration with all the other products that we have from Microsoft is valuable. We're using the E5 license, and we have a whole wealth of different products available. It just makes it easier to have everything from one provider."
"The most valuable feature of Microsoft Intune is that it is more of a one-stop shop, providing an easier experience."
"The solution is fully integrated with the Microsoft platform and the Autopilot feature, which is a unique feature."
"It is a comprehensive security solution that not only controls access to enterprise resources but also tracks and prevents unauthorized access, ensuring the protection of sensitive data and preventing potential data loss scenarios."
"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."
"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 can also monitor our systems at any time from practically anywhere."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"The most valuable feature has been the ability to give control to others for support purposes."
"The quality of the call and the quality of the sharing have been excellent."
"There have been a couple of times with the handy remote access feature, where I have been asked for something at eight o'clock on a Thursday evening and it is on my desk machine, but I am driving back to my office. With TeamViewer, I can just stay at my home machine, connect to my work machine, and get the data needed without having to drive back across town."
"TeamViewer Business has positively impacted my organization by boosting efficiency since you do not need to be physically available to the client to troubleshoot or help them."
"The most important feature of TeamViewer is its ease of use."
"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."
"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."
"The most valuable features of TeamViewer are the high performance and it is not complicated to use, neither for me nor for the one I'm helping."
 

Cons

"We only have major classifications for iOS and Android, but there are different brands that have different cycles of updates. If they can fine-tune it to make it more brand-specific, that would be even better."
"In the past, I raised some tickets for the enhancement feature, which was missing in Intune."
"The initial setup is a little bit complex."
"Cost is the biggest factor for us right now. Microsoft Intune and AD P1 together in a bundle is a good thing to have, but it is very costly compared to other products in the market. Otherwise, Microsoft Intune is the best."
"You can have a bad day where 80% of the enrollments failed. The next day it's running with the same devices without any changes, and you don't know why."
"More integration with monitoring tools is needed."
"I'd suggest adding more features for macOS in Intune. There should be more functionality for managing macOS. There should be a better capability for pushing things down on macOS. Currently, Intune is not capable of managing macOS at the same level as Windows."
"We would like to see support for Chrome and/or devices for Chromebooks."
"They need to better advertise the features."
"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."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"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 be able to access and manage all brands of smartphones."
"The security could improve in TeamViewer."
"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."
"If were to I put myself in the seat of a small business owner, I would prefer TeamViewer to be more of a pay-once-and-own-it solution, rather than paying via a subscription model (although I am using the free version). Only annual subscriptions are available. It makes paying for it the first time seem a little daunting."
"It should have ability to display notes in the computer list."
"TeamViewer could be more secure."
"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."
"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..."
 

Pricing and Cost Advice

"It's monthly for us, but it's built into the license cost that we pay our IT each month. It's maybe 129 Kroner per head, which translates to £10. There are some additional costs. Our IT had to set up and configure their own server, so there is an extra cost for that, but I'm not sure what that costs."
"I don't have any problem as far as cost is concerned. It is bundled with our license."
"The product is offered as part of a Microsoft standard bundle. The pricing can be competitive to Airwatch, and Maas360."
"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."
"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."
"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."
"Based on the features that it gives, it is cost-efficient. It is not necessarily on the expensive side of the scale. It provides a hefty number of features that any organization would want. It is in a good price range."
"I have no comment on pricing of the solution."
"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 have an annual subscription that is just under $1,900 with no additional costs. We get these promotions about upgrades and stuff like that, but we haven't had a need to add more seats. Users can also use TeamViewer for home use with a non-commercial free license."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"TeamViewer has multiple licensing options."
"We are using the standard free version of TeamViewer."
"I used the free version of TeamViewer."
"It would be nice if it is cheaper."
"We are using the free version of TeamViewer."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
