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

"Overall, my user experience with Microsoft Intune has been great."
"The insights, even though we're talking about charts and graphs, are super valuable to customers who might not otherwise know what's in their ecosystem or the current state of things within their ecosystem."
"Intune's feature that I have found most valuable is its auto-pilot feature."
"The ability to work from all over the planet is valuable. You just need a functioning and working Internet connection."
"A great solution for anyone wanting a modern endpoint device management solution."
"One of the most valuable aspects of Microsoft Intune is its seamless integration with Azure Active Directory, offering capabilities akin to Group Policy Objects."
"It helps implement conditional access policies to restrict mobile users from accessing potentially dangerous emails."
"Overall, I like Intune as a solution and would rate it nine out of ten."
"Setting up the solution is easy and there's no maintenance involved."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"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."
"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 product is quite stable. The performance is good."
"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."
"The product is easy to install."
"TeamViewer has a lot of options for deploying the Hosts, where you can mass deploy them very easily, and you can pre-configure them."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
"It is quite simple to set up."
"The solution is very stable. We've never had a problem with it."
"TeamViewer Business has positively impacted our organization by reducing the time of the TAT for resolving issues for end users, which has really helped us."
 

Cons

"There can be more logs. I do not have any other requirements."
"Reporting and troubleshooting for the application deployment could be better. It's very difficult to understand."
"Microsoft Intune's support for Mac devices is lacking and could be improved."
"There are a lot of updates coming from Microsoft that suddenly affect our security policies."
"The reporting dashboard is really limited."
"Lacking ability to leverage more iOS device management internally."
"I switched away from Microsoft Intune because it cannot manage the MacBook very well."
"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."
"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."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"There could be a section in the menu describing the new features and changes."
"I would like to be able to access and manage all brands of smartphones."
"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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"One thing I have noticed is that TeamViewer does not work so well when the machine you are trying to connect to remotely is not running the same version as your machine."
"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..."
"If they could figure out a little better solution for the iOS stuff other than just a screen share, even though it's an Apple thing, and Apple doesn't like to give up control of their devices. If they ever got to that point, and I could manipulate an iPad or iPhone, that would be awesome. Since we have a bunch of iPad users who are struggling with doing different things, it would be nice to be able to just jump on and actually show them, "Here, do this, this, and this." Similar to what we do with the laptops, e.g. for training."
"The installation and the update agent could improve."
"It's pretty limited on the options they have."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"I think the pricing could have been improved, as smaller organizations like us usually need a low-cost tool."
"They could give more information about using certain kinds of applications for secure transactions, such as secure file transfers."
 

Pricing and Cost Advice

"Generally, we get favorable discounts, so it's not too bad. Obviously, we're looking at decreasing those wherever we can to bring value back to the public purse because it's all charity based. It's all publicly funded."
"It is average. Some of the costs are quite high depending on what the customer currently uses, but overall, it is not bad. I would not say that I would not recommend Intune based on the cost. I definitely would, but they can definitely improve on the cost. So overall, its cost is not bad."
"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."
"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"Its price is quite okay. I wish they provide certain additional features with the same license."
"Microsoft Intune is available for individual purchase at a low per-device cost."
"It is not a cheap solution. The price for a device when you start using it at a large scale can be improved. It is covered under our enterprise agreement. We pay once a year. I am not aware of any additional costs."
"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."
"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."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"TeamViewer pricing is reasonable... The simultaneous controller licensing model of TeamViewer - compared to LogMeIn’s controlled Host licensing model - seems to benefit us so far. We’re currently saving about 30 percent on licensing cost... The savings from licensing have been eaten up by the soft costs involved in dealing with and working around TeamViewer’s deficiencies in allowing granular control by multiple controllers, and the issues with the various settings that are missing on the macOS Host."
"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)."
"TeamViewer was willing to give us a one-year package. Whereas, a lot of the other companies that we explored were paid by the month or quarter. It's just easier for our finance people at the college if we can make a one-time yearly payment."
"We are using the standard free version of TeamViewer."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
"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 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."
