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.
ErikDas - PeerSpot reviewer
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.
GouravSuri - PeerSpot reviewer
Easy to use and offers a good UI to users
In terms of the product's security features, the solution allows you to have team meetings, and you can also use it for remote access and screen-sharing capabilities. TeamViewer is typically like any other team collaboration software. I recommend the product to others since it is a good product for collaboration purposes. There are no connectivity challenges associated with the product. In terms of benefits, I would say that it is a good tool for collaboration, productivity, and virtual work as it saves a lot of commute time for the employees. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"Its price is reasonable. It is a part of our M365 suite."
"One of the most valuable features of Microsoft Intune is the detection and remediation script capability."
"The best features in Microsoft Intune that I appreciate most are its centralized features."
"The most useful features in Microsoft Intune are the policy enforcement and conditional access. These features make our operations easier from a company perspective."
"It's really easy to access."
"We can securely manage both company-owned devices and personal devices enrolled in our BYOD program."
"I mainly use Microsoft Intune analytics for taking that data that exists and bringing it into Power BI dashboards to make it visible to our clients, showing them all the operating systems in their environment and where the latest patches are, and then from there creating plans."
"Intune does consolidate all endpoint and security management tools into one place, making everything easier to manage."
"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."
"I personally really appreciate the file transfer feature as it is really easy to use."
"We can also monitor our systems at any time from practically anywhere."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"The most valuable feature is safety."
"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 solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"The product allows easy access to any system in case of any issues."
"The product is quite stable. The performance is good."
"TeamViewer is fast and easy to manipulate."
"The most valuable features of I use TeamViewer are the ease of access and frequent updates."
"From my perspective, the most important is the login."
"The solution is a very good tool for monitoring and for remote access. Anyone is able to use it, it is simple to use."
"The most valuable feature of TeamViewer is the ability to remote into another device."
 

Cons

"Intune should be much more granular in terms of supporting more Android cellular devices."
"The reporting dashboard is really limited."
"Currently, BitLocker does not support BYOD enrollment, which is a product limitation."
"I think there should be a better tracking of the cell phones used on the Intune."
"There should be more predictability in the release cycle. We don't feel we have any control over when new updates come out, and whether there are changes to the backend functionality or to the user interface. Updates just happen."
"Sometimes the syncing is inconsistent. I'm confident that the devices are checking in every eight hours, but sometimes the devices aren't picking up the settings as quickly as I would expect."
"Microsoft Intune lacks the ability to provide seamless remote assistance or remote control."
"I wanted to check if there is any provision at the Intune level to restrict certain things, such as a website, but unfortunately, that feature is available only in Microsoft Defender. Intune has web filtering capabilities, but they are only useful for protection from malicious websites, whereas we would like to be able to restrict a website. For example, YouTube is a clean website. No one would identify it as a malicious website, but if we want to stop the end-users from going to that website, we have to go for another product, such as Microsoft Defender or another third-party proxy solution. It would be great if this capability is included in Intune."
"It would be helpful if they had iSupport for supporting Apple phones."
"They need to better advertise the features."
"I would like to be able to access and manage all brands of smartphones."
"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."
"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."
"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."
"TeamViewer could be more secure."
"A feature that they could add is chat with sound to talk."
"It would be very helpful if they could provide a manual for the installation process and describe more of their features."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"We'd like to be able to work from mobile to desktop and vice versa. We'd like more mobility."
"The business interface is clunky and not well-documented."
"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."
"Every now and then you'll get a silent crash and you relaunch the application. But it happens no more than with anything else in the Windows environment."
 

Pricing and Cost Advice

"Microsoft Intune is a cost effective choice. It is less expensive than other products on the market."
"The Intune license model is costly."
"Its price is quite okay. I wish they provide certain additional features with the same license."
"I am satisfied with the pricing."
"Microsoft Intune is more expensive than other solutions, but it offers a wider range of features and control."
"Its pricing seems reasonable."
"Intune is included in the Microsoft 365 licensing package that we have."
"Intune is cost-effective as it is included in some of the Office 365 packages."
"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 are using the free version of 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."
"The solution's pricing is reasonable."
"The price of the license could be less expensive."
"I used 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."
"We are not using the solution for commercial use therefore it is free to use."
"TeamViewer is $600 or $700 per port per year..."
