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.

Lead Software Engineer at BD
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

"As the solution is a software as a service, the scalability is unlimited."
"Technical support is good."
"The most valuable feature is the policy CSPs."
"The ability to send configurations to our systems is valuable, particularly as we don't have a regular Windows AD server. Our current environment doesn't have a Windows AD, which limits our ability to push GPOs. However, this is where the solution can step in and help us push policies."
"Application deployment and keeping the devices secure no matter where they are, by having this cloud solution — that has been great."
"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."
"Autopilot is the most valuable feature."
"The one feature we find most useful is the Mobile Application Manager; we don't give our users phones, it is their own personal phone, and we need to allow them to have access to the company data on their phone while creating a balance between their own personal data and the company data so that we won't be able to interfere with their own personal data."
"We can also monitor our systems at any time from practically anywhere."
"Without ISL Online, I would not be able to work from home."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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."
"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."
"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."
"It's very beneficial and time effective on how we are able to provide quick support. We've quadrupled our effectiveness as an IT support because we have cut down all that unnecessary travel time, even between floors."
"The most important feature of TeamViewer is its ease of use."
"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 most valuable feature of TeamViewer is its ease of use and beneficial remote access."
"This solution has been really useful when doing product installations and needing assistance."
"It's very easy to set up."
"The most valuable feature of TeamViewer is its ease of use."
"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

"One area for improvement is app deployment. Another is the Windows update rollout. If you're rolling out an object to a device that's offline, Intune stops trying to reach this device after it sits idle for a bit. We are forced to find a workaround that could help manage that."
"I want more secure, reliable, and efficient security policies."
"There's a significant discrepancy in Intune pricing between tenants."
"There should be more focus on mobile device security and integration."
"Intune has all the features enabled for Windows devices but needs to be improved on iOS and Apple devices."
"Microsoft Intune has a few areas where it could improve, such as faster policy and app deployment, a better user interface, stronger support for non-Windows devices, improved reporting and visibility, easier troubleshooting tools, and more transparent pricing."
"At the moment, we need more flexibility. We have some offices migrating to Windows 11 remotely. Sometimes, it is difficult to manage image installation because we have to collect some information before starting image deployment. Currently, Intune cannot collect the information needed for deploying new images."
"Intune should improve its software inventory to provide better metering of which software is used throughout the company. This is especially needed for reporting third-party software solutions."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"We miss the possibility to communicate via head-set in ISL."
"They need to better advertise the features."
"It would be helpful if they had iSupport for supporting Apple phones."
"What bothered me the most was that when I connected to the computer at the office, I was afraid that someone would turn on the monitor and watch what I was doing."
"The solution could improve by increasing or removing the time limitation on the use of a session."
"TeamViewer is publicly available and anyone can use it. This is the reason that many organizations do not permit the use of this solution."
"The file transfer functionality crashes sometimes."
"I believe there are aspects of TeamViewer that could work better, particularly in the integration of various tools."
"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."
"But still, I think the price factor for small business."
"The performance could always be better."
"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."
 

Pricing and Cost Advice

"The price for Intune is fair."
"Intune is inexpensive. It also comes bundled in some Office 365 licenses, so you can choose to purchase it separately or as a package."
"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."
"We have the business premium licenses for the solution."
"We are partners, so we receive some discount. However, from the customer's perspective, Microsoft Intune's pricing is competitive with non-Microsoft technology, and the price is good compared to other market competitors."
"I recently got to know that the AD P1 license is compulsory to use Intune Autopilot, which was surprising for me. Earlier, this was not the case. It is the wrong thing to do. We now need to purchase AD P1 licenses for us and for our customers. I would rate it a seven out of ten for pricing."
"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."
"The price is very reasonable."
"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 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)."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"We have a permanent license and the price is reasonable."
"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 is $600 or $700 per port per year..."
"We are not using the solution for commercial use therefore it is free to use."
"There is a free and paid version of this solution. I am currently using the free version."
