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

"Comparing this to having an endpoint management solution, the efficiency gain may be up to 80%."
"When comparing Microsoft Intune to Jamf, Microsoft Intune is superior."
"As an IT administrator, I appreciate Intune's ability to implement granular device-level policies for our organization's employees."
"Its price is reasonable. It is a part of our M365 suite."
"One of the most valuable aspects of Microsoft Intune is its seamless integration with Azure Active Directory, offering capabilities akin to Group Policy Objects."
"The most useful features in Microsoft Intune are the policy enforcement and conditional access."
"We have found the solution is capable of scaling."
"Intune saves time, and it is very easy to use. It allows us to manage applications completely."
"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."
"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."
"We can also monitor our systems at any time from practically anywhere."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"It is quite simple to set up."
"The quality of the call and the quality of the sharing have been excellent."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"TeamViewer is stable."
"The TeamViewer system has some built-in security. The TeamViewer client connects to the TeamViewer host securely. Only a certain number of authorized users on our side have access to the system. Even within that, an individual endpoint can be assigned to a group, where not everybody has access but, rather, just one or two people who are part of a support team might have access to that particular device. So TeamViewer has given us tools to be able to segregate who has access to different things."
"The most valuable feature of TeamViewer is the ability to remote control a computer system. Overall it is a complete solution."
"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."
"The most valuable features of I use TeamViewer are the ease of access and frequent updates."
 

Cons

"The add-ons must be integrated into the solution."
"I want more secure, reliable, and efficient security policies."
"Microsoft Intune lags market leaders, such as Apperian, in its MAM capabilities."
"When we implemented Intune, it would have been helpful if Microsoft had provided some videos or data about Intune."
"The biggest problem we ever have is when something goes out of date after 30 days when nobody has logged into it. We do have a problem trying to get those back online. We've been working with Microsoft to resolve that problem, but that's been the only issue that we've had in the last few years."
"I also hope the cost of Remote Help will decrease because it's a much-needed Intune function."
"Every time we call, we get bounced to a new team... there is no cohesive end-to-end support, which is very frustrating and time-consuming."
"The interface is easy, but it is not user-friendly when evaluating the overall user experience of Microsoft Intune."
"There could be a section in the menu describing the new features and changes."
"It would be helpful if they had iSupport for supporting Apple phones."
"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 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 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."
"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."
"The performance could always be better."
"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."
"I didn't like the fact that you had to install a client for remote support. If you didn't install the client, you were very limited in terms of what you could do. For a whole enterprise, it is just not an easy task to install a client on everything. Even if you're using SCCM, it is an undertaking. For transient clients that you don't necessarily support a hundred percent of the time, it would be nice to be able to connect to them and support their issues without having to install something on their machines. In my previous company, we were looking at this solution as being a collaborative tool for the enterprise in terms of video conferencing, calling, and scheduling. They were working on bringing a bunch of products together to make their suite a little more integrated, but it really wasn't at the point where we wanted it to be in terms of integration. We looked at it, reviewed it, and tested it out a bit. We then decided to go with Microsoft Teams. It has the clunkiness of having separate modules that aren't totally integrated. There are different methods for doing different things, which makes it a little bit more complicated. There should be the same way whether you are doing remote support or just calls."
"They should release features such as Augmented Reality into both plain and standard versions of TeamViewer."
"TeamViewer Business's scalability is bad because it's very expensive."
"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."
"TeamViewer has a legacy and may not be using the latest UI trends."
 

Pricing and Cost Advice

"Intune's pricing is reasonable considering its benefits and the high costs it helps avoid."
"I am not that aware of the pricing, but as compared to other MDM solutions, Microsoft is providing a lot of things at the organizational level. So, it is quite reasonable as compared to other MDM solutions."
"The pricing is inherently reasonable, as Microsoft leverages market insights to maintain the total cost of ownership at around ninety to ninety-five percent of what would be incurred in an on-premise scenario."
"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."
"Microsoft licenses are costly."
"Its price is fair. It's a normal price. It isn't too expensive or too cheap."
"There is a cost benefit of using Microsoft Intune because of the packaging with other Microsoft products."
"While Microsoft Intune boasts a wide range of features, its user-friendliness and bundled licensing cost are key considerations for me."
"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."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"The price of the license could be less expensive."
"We use the free version of TeamViewer."
"The cost of the licenses depends on how you buy them. They just had a buy one get one free deal going, and they do that every once in a while. Where you buy one license, and they will give you the second one free, or you can try to get discounts. Most of our licenses that we have we tried to do something like that just to save some money."
"The cost is in the thousands of dollars per year."
"We are not using the solution for commercial use therefore it is free to use."
"TeamViewer is very pricey. You have to sign up for a yearly subscription."
"We are using the free version of TeamViewer."
