Modern endpoint management has transformed onboarding and strengthened remote security controls
The features of Microsoft Intune are straightforward, including Windows Autopilot, zero-touch deployment, centralized device management, and conditional access security controls. Using zero-touch deployment and Windows Autopilot in Microsoft Intune has significantly improved my workflow and organization. New laptops are shipped directly to users with no IT handling needed, and there is no manual imaging or configuration required. These features have a real impact. They save hours of manual setup per device, reduce dependency on the IT team for basic provisioning, and ensure every system is configured consistently and securely. Microsoft Intune has positively impacted my organization by improving device management. Devices are managed from a single cloud console. It has reduced manual work for provisioning and configuration. It has faster onboarding using Autopilot. It has enhanced security posture through enforced compliance policies, encryption, antivirus, and password rules. Conditional access ensures only trusted devices can access resources. I have better support for remote users, as devices can be managed from anywhere with no dependency on office network or VPN for basic management. It has easy troubleshooting and policy updates.

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.

Reliable remote access has improved secure collaboration and streamlined daily approvals
The best features TeamViewer Business offers in my opinion are collaboration, templates, a high level of security, and session recording. Collaboration allows me to collaborate remotely with my team members. Besides reconnecting automatically, it provides a high level of security, protecting from cyber attacks and aids in providing assurance in regulated environments through two-factor authentication and end-to-end encryption features. It also allows recording live sessions, which can be replayed as needed for future reference. TeamViewer Business has positively impacted my organization as collaboration has enhanced, especially remote collaboration by 60 to 70 percent. I have been able to collaborate with clients and other team members seamlessly. Enhanced workflow efficiency includes faster approvals and a lowered risk of data loss, misuse, and leak through robust features like two-factor authentication and end-to-end encryption. It also facilitates compliance using documentation and auditing through recordings and logs.

Quotes from Members

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

Pros

"We have definitely seen a good return on investment, as it has saved a good amount of time in device setup and support, reducing manual effort by around forty to fifty percent and also fewer on-site interventions since most issues are handled remotely."
"I appreciate how clear Microsoft Intune is."
"Stable solution at a good price."
"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."
"Microsoft Intune has broad capabilities, particularly with mobile device management, with excellent management features like the ability to push configuration policies to all devices across the company and manage them effectively, strong configuration and compliance capabilities, and valuable application management that centralizes applications in one place and makes configuring or deploying them much easier."
"It has helped with compliance. It has helped to ensure that devices comply with the organization's policy. If they are not compliant and secure, they cannot access the resources."
"Microsoft Intune benefits my company because of its simplicity of use and cross-functional integration."
"We handle the distribution software, collect metrics for app usage, and create policies to make the device compliant for Microsoft Intune."
"The stability is great; reliability is what's very important to me, as well as security, and this solution may have only had one instance of downtime in 14 years."
"We like drawing utilities inside ISL. That helps us mark specific regions on the screen, so that end users know what to focus on."
"We can also monitor our systems at any time from practically anywhere."
"I personally really appreciate the file transfer feature as it is really easy to use."
"ISL is a fundamental partner for us since, throughout all these years, it has allowed us to grow and solve the problems of our customers and their users in a very fast and agile way without having to move, even providing service abroad."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Ease of use was the number-one thing. It's an industry leader for ease of use, specifically on the client-side, which is the absolutely critical thing. If I want to connect to somebody, how easily can I — without seeing their computer — walk them through the steps to install it to a point where I can key in the code and help them resolve their situation?... TeamViewer is just a dead-solid, easy answer."
"In the years I have used TeamViewer, everything that I missed was already added."
"The most valuable feature of TeamViewer is the ability to remote into another device."
"Saves travel time, and wide support of platforms allows for a single solution."
"It is a great, amazing tool; all companies need to have it, and it's secure, fast, and reliable."
"The solution is a very good tool for monitoring and for remote access, and anyone is able to use it because it is simple to use."
"The technical support team assists with TeamViewer and performs repairs and installations remotely."
"TeamViewer is useful for accessing data and systems remotely. Using this application, I can access other computers using an ID number that I provide to the users whose laptop I would like to access."
 

Cons

"Intune should be much more granular in terms of supporting more Android cellular devices."
"The tool's tunnel gateway is not very good, making it an area where improvements are required."
"It should be easier to define policies and comply with those policies."
"One major concern I have is user friction. When you enforce many policies and people log into apps like Microsoft Teams or Outlook, they encounter numerous MFA and other policies."
"Microsoft needs to enhance device-level security, as sometimes when using Microsoft Intune, the device's operating system becomes stuck and requires a full uninstall to remove the Intune bug."
"It needs certificate provisioning for S/MIME purposes."
"Intune should improve the management of non-Microsoft devices. It would be better to manage Mac, Android, and other non-Microsoft operating system devices within the same Intune interface."
"Lacks the ability to deploy more ways of management, managing devices and processing the policies."
"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."
"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 could be a section in the menu describing the new features and changes."
"We miss the possibility to communicate via head-set in ISL."
"There could be a section in the menu describing the new features and changes."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"When clients have a newer version installed and we only have a license for version 8, there are issues."
"The business interface is clunky and not well-documented."
"Quick User Switching has a very nasty tendency to render the screen output unstable."
"Unfortunately, the software is hit or miss when it comes to iOS devices, especially Macs."
"I had an issue recently where my mouse clicks weren’t being registered."
"The stability of TeamViewer is good, but it could be better."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"TeamViewer has a legacy and may not be using the latest UI trends."
 

Pricing and Cost Advice

"The licensing is on a yearly basis."
"There is a license required to use this solution. However, it was part of a bundle package. Microsoft Intune is far less expensive than other solutions, such as Workspace ONE."
"Intune is available as an individual product, but it also comes with Office 365 Premium or an Enterprise license, and the price varies for each version."
"It is cheap, but as compared to Google, it is costly. Google is cheaper, but quality-wise, Microsoft Intune is better."
"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."
"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."
"Existing E5 license holders for M365, Intune, and Azure, receive a free license."
"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 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."
"There is a free and paid version of this solution. I am currently using the free version."
"The cost is in the thousands of dollars per year."
"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 is very pricey. You have to sign up for a yearly subscription."
"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."
"There is no license needed to use TeamViewer."
"The pricing is a little bit on the higher side."
"TeamViewer's price is cheaper than some other similar solutions. We have licenses for our users."
