Executive SummaryUpdated on Nov 2, 2025

TeamViewer Business and ISL Online are two leading remote access solutions competing in the industry. TeamViewer Business seems to have the upper hand due to its robust remote access capabilities like firewall bypassing and multi-platform compatibility, while ISL Online is preferred for its secure and straightforward user interface.

Features: TeamViewer Business offers seamless remote access by bypassing firewalls using standard internet ports, cross-platform compatibility across Windows, Linux, Mac, and Android, and facilitates remote control and file exchange with speed and reliability. ISL Online is noted for its secure unattended access, reliable connection stability, and easy setup process, making it highly valued for remote support and file transfers.

Room for Improvement: TeamViewer Business could enhance inter-version compatibility and improve clipboard and file transfer functionalities. Handling multiple simultaneous sessions and addressing inconsistencies in drag-and-drop features are additional areas for improvement. ISL Online would benefit from enhanced feature notifications and better support for Apple products, including integration support for mobile devices. Both could refine session management for multiple operators.

Ease of Deployment and Customer Service: TeamViewer Business supports a variety of deployment options, including on-premises and public cloud setups but primarily targets on-premises environments. ISL Online offers similar deployment flexibility with ease in both on-premises and cloud options. Both solutions provide excellent customer service with responsive support and effective resolution, although some TeamViewer users may encounter longer wait times.

Pricing and ROI: TeamViewer Business offers free and licensed options, though the pricing may be steep for smaller businesses, it is justified by productivity gains. ISL Online is viewed as reasonably priced with flexible payment options and discounted bulk purchases, encouraging new users to try evaluation licenses to assess ROI potential.

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 ability to switch between Affinity and non-Affinity enrollment is great."

"It is more efficient to have one solution rather than having security parts spread across three, four, or five solutions."

"The interface is user-friendly, and the reporting tool works in real-time."

"The best feature is that we don't need to worry about downtime. We don't need to worry about the network connections of our office or the virtual private network. Everything is being done through the internet. Using Intune Autopilot, we can configure and deploy everything to the devices."

"A great solution for anyone wanting a modern endpoint device management solution."

"The mobile application management, MAM, is the most useful aspect of the solution."

"What I like most about Intune is its seamless enrollment process, particularly the Autopilot method."

"We handle the distribution software, collect metrics for app usage, and create policies to make the device compliant for Microsoft Intune."

More Microsoft Intune pros

"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."

"It's much easier to connect with other services, and it's working great. We haven't had any problems."

"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."

"I personally really appreciate the file transfer feature as it is really easy to use."

"Setting up the solution is easy and there's no maintenance involved."

"We can also monitor our systems at any time from practically anywhere."

"The most valuable feature is safety."

More ISL Online pros

"There is a relevant return on investment, especially when my previous organizations assisted with remote access features, as rather than needing to go on-site, we could connect remotely, making it easier for those who are not tech-savvy, thanks to TeamViewer Business's user-friendly features, which helped immensely, especially when assisting elderly clients, and ensured we met metrics effectively, creating a significant positive impact."

"Using TeamViewer for my personal clients has made things much better for me and my clients because my clients are happy to resolve a problem within seconds via TeamViewer."

"I have found the solution to be user-friendly even for beginners. It is not that sophisticated. There are different types of security features available, such as encryption and random machine ID."

"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."

"It's a user-friendly product."

"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."

"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 feature of TeamViewer is the remote access connection. Additionally, it is easy to use."

More TeamViewer Business pros

Cons

"I rate Microsoft support between six to eight. The support often involves third parties hired by Microsoft who are knowledgeable, but sometimes the help I receive is not adequate."

"The initial setup is a little bit complex."

"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."

"The security aspect could be more effective."

"I have experienced downtime, bugs, and glitches. I rate it a seven because when we have bugs or instability in Microsoft Intune, we need to wait for the backend from Microsoft Intune to resolve issues and we can't deliver solutions to clients because we need to wait for action plans and related processes."

"The granular support for other device types in Microsoft Intune could be improved."

"They should make it easier to order it, however, that's generally true for everything from Microsoft."

"The backend of Microsoft Intune needs to be improved. We have seen a little bit of delay as compared to other MDM solutions. That needs to be improved. A little bit more granularity should also be added"

More Microsoft Intune cons

"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."

"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."

"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 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."

"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."

"They need to better advertise the features."

More ISL Online cons

"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."

"The solution could improve by increasing or removing the time limitation on the use of a session."

"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."

"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."

"TeamViewer Business can improve in terms of price and the complexity of licensing, which is a drawback, especially for smaller teams or casual users due to frequent license changes and forced upgrades."

"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."

"The support could improve their speed."

"The business interface is clunky and not well-documented."

Pricing and Cost Advice

"I don't have any problem as far as cost is concerned. It is bundled with our license."

"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."

"We have a limited budget for security investments, so Microsoft should consider reducing pricing in our region. This would make investment more viable, especially since larger businesses in other countries can afford it easily."

"It's affordable. In comparison to the competitors, the price depends on what features you need from Intune, but it's affordable. There are no hidden costs, but there are some features that go for a premium price. Those are the add-ons for which you have to pay extra."

"For organizations that are a Microsoft shop, the pricing is compelling."

"Microsoft offers some licensing where it's included at no extra cost when customers are already using the licenses. In such a case, it's a really good value. If you have to buy the licensing for it, it's probably on par with other solutions. It isn't substantially more or less expensive. The great thing is that it is included in some of Microsoft's licensed packages. So, some customers don't have to spend additional money for it. Typically, most providers that support Intune do charge a management fee of some sort or some fee. Certainly, we're no exception."

"It's bundled with Business Premium and an E3 license, which is beneficial. If you have to pay extra, it's pricey, but with the bundled package, it's acceptable. They recently increased the Business Premium pricing, which we don't appreciate. The price increase and yearly commitment are causing some problems for us."

"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."

More Microsoft Intune pricing and cost advice

"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 price of the license could be less expensive."

"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through 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."

"We use the free version of TeamViewer."

"The version of the solution we are using is free."

"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."

"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."

"TeamViewer has multiple licensing options."
