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

"Intune helps the organization manage access to its internal apps, data, and resources."
"I like the fact that it's integrated with the rest of the Microsoft products, so customers can manage it from their Office 365 portal or Azure portal."
"This is a great solution for anyone wanting a modern endpoint device management solution."
"Great for software update needs, operating system version updates, and security policy enforcement."
"Intune provides full endpoint visibility and IT control across device platforms. You can individualize it for your company with the Intune Company Portal app."
"The most valuable features are the ones that make sure that the deployment is of a standard operating system and the Zero Touch deployment, which is very useful, allowing users to have an out of box experience."
"The mobile device management is very useful."
"It is a comprehensive security solution that not only controls access to enterprise resources but also tracks and prevents unauthorized access, ensuring the protection of sensitive data and preventing potential data loss scenarios."
"Good communication is a key to good business and ISL helps a lot."
"I personally really appreciate the file transfer feature as it is really easy to use."
"We are just much more responsive, we can be faster, and we can support our customers in a better way because when they have a problem, we can be on their computer immediately."
"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."
"Without ISL Online, I would not be able to work from home."
"The code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"The most valuable feature is safety."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"The most valuable feature of TeamViewer Tensor is the remote access."
"Unattended access with single login."
"The solution has worked flawlessly; it’s stable and reliable, with no bugs or glitches."
"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 don't know of any performance problems with TeamViewer - generally, it's a stable product."
"TeamViewer is fast and easy to manipulate."
"TeamViewer is a scalable solution."
 

Cons

"Having a dedicated configuration server that assists in modifying the configuration service, and creating personalized structures, interfaces, and web services could enhance usability."
"I rate Microsoft support four out of 10. Support is one area where Microsoft needs to improve a lot. I recently raised a ticket for a Microsoft Azure issue, and it took two and a half weeks for support to reply. They need to improve support across their entire catalog of products."
"Automatic updating is pretty rough. It doesn't give me as much control as I had in the past."
"A detailed device diagnostic feature is missing. Also, operating system deployment and imaging are missing."
"Intune is a good product for UEM, which is helpful for Windows 10 management. However, for MAM, there is lots of improvement needed."
"Customer service is not really good. I would give it a six out of ten. The main issue is the time it takes to get someone involved who truly understands what the product does."
"Intune's third-party patch management could be better. It should be easier for the average system admin to keep non-Microsoft applications updated."
"There are items that require improvements. One is the controls from iOS."
"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."
"I would like to be able to access and manage all brands of smartphones."
"They need to better advertise the features."
"It would be helpful if they had iSupport for supporting Apple phones."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"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."
"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 performance could always be better."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"The file transfer functionality crashes sometimes."
"I would like to see TeamViewer support multiple platforms."
"TeamViewer could improve by having support for other operating systems, such as Linux."
"You can't configure multiple, unattended control passwords on the Mac. On the Mac, there's only one. On Windows, there are multiple unattended control passwords. I have people in different departments. My infrastructure people need to control a server and my developers may need to go into that same server. But I don't want them to have the same password... on the Mac, it can be done but it's extremely clunky and problematic."
"This solution could be improved by offering more flexibility in terms of usage."
 

Pricing and Cost Advice

"For organizations that are a Microsoft shop, the pricing is compelling."
"Intune's pricing is competitive. For example, the license of Blackberry's Enterprise Mobility Suite was costly, but Intune is affordable. It is included as an additional feature when you buy security enhancements for your organization. For example, let's say I have fifty users in my organization and all of them are using Microsoft cloud services, like Teams, Office 365, and OneDrive."
"The solution is cost-efficient."
"We work with the subscription rather than a server license. I think it's economical this way because we don't have to have a server license for that, and I think that works in our favor."
"Existing E5 license holders for M365, Intune, and Azure, receive a free license."
"Microsoft Intune is a cost effective choice. It is less expensive than other products on the market."
"It's reasonable. They're not giving it away, but it's reasonable."
"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."
"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."
"TeamViewer was willing to give us a one-year package. Whereas, a lot of the other companies that we explored were paid by the month or quarter. It's just easier for our finance people at the college if we can make a one-time yearly payment."
"The price of the license could be less expensive."
"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..."
"The cost is in the thousands of dollars per year."
"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."
"We are using the free version of TeamViewer."
"I rate pricing a ten on a scale from one to ten, where one is low and ten is high. There are no additional costs attached to the licensing of the solution."
