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

"The stability of Microsoft Intune is ten out of ten."
"The most valuable feature of Microsoft Intune is that it is more of a one-stop shop, providing an easier experience."
"Windows Autopatch is the most valuable because it removes the burden of patch management."
"The most valuable feature of Intune is the central dashboard for compliance and policy management."
"I appreciate how clear Microsoft Intune is."
"The pricing for Microsoft Intune is reasonable and our clients are satisfied."
"Microsoft Intune helps us avoid issuing everyone company-owned devices. We provide a stipend, allowing users to bring their own devices. This approach gives us leverage against other MSPs. It also enhances collaboration because clients already covered by specific licensing can optimize their usage of Microsoft Intune."
"The aspects I find most valuable are the managing the data and applications. I can also restrict the users to install any applications. I can also wipe the data if the phone was missplaced or stolen. These are the basics for me."
"I personally really appreciate the file transfer feature as it is really easy to use."
"Without ISL Online, I would not be able to work from home."
"Setting up the solution is easy and there's no maintenance involved."
"We can also monitor our systems at any time from practically anywhere."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"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 most valuable feature is safety."
"There are only two of us in the core of the company and we manage about 500 machines based in the UK, mainland Europe, US, Hong Kong, China and South Africa."
"In my opinion, it's the best remote access product on the market."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"The usability and graphic interface stand out for me because it is very easy to understand, with upper bars, all the features, and the file transfer functionality."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"TeamViewer has a good interface."
"We also use it a lot for remote site assistance. We've set up our internal authentication for unattended access to our remote sites. That makes it very easy and convenient to remotely connect with our users and our client machines whenever we need to. It's set as a direct, secure connection. As long as the station has internet access, we can see it and it makes remote support very simple."
"We've quadrupled our effectiveness as an IT support because we have cut down on unnecessary travel time, even between floors."
 

Cons

"Intune needs to incorporate more tools to reduce the number of third-party applications we rely on."
"I switched away from Microsoft Intune because it cannot manage the MacBook very well."
"However, I dislike how it lags sometimes. I cannot work on multiple processes at the same time."
"An area for improvement is the absence of seamless integration, particularly with external dashboards."
"The reporting functionality of Microsoft Intune is limited compared to Microsoft System Center, which offers many more reporting options."
"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."
"Technical support is not that great."
"They can improve their MAM policies a little bit more and make them more granular. They should include more granular group policies. They are there, but they need to be more granular. Its stability should also be improved. It is not very stable. Sometimes, it shows some inconsistencies across tenants."
"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."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"I would like to be able to access and manage all brands of smartphones."
"We miss the possibility to communicate via head-set in ISL."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"They need to better advertise the features."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"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."
"If you had to teach someone how TeamViewer Business works, especially because I am speaking in a sense that I am using it on an engineer level, it would be a bit difficult to get accustomed to some of the settings, especially with the new experience."
"We access the solution through a VPN, which improves our security. However, earlier this year, around the beginning of March, a CVE in the TeamViewer client allowed remote connections to other network systems, which was concerning. You could have unintentionally gained admin rights if you didn't update TeamViewer promptly. It's crucial to always keep it updated to prevent such issues. The tool should consider implementing two-factor authentication to improve such security holes. It should also integrate good security updates, which should be implemented automatically."
"There is a limit on the number of people who can attend a meeting. Currently, I use Zoom for our pre-construction meetings because I can have up to 25 people."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"We have a consultant that helps us do the virtual aspects of TeamViewer."
"The installation and the update agent could improve."
"But still, I think the price factor for small business."
"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."
 

Pricing and Cost Advice

"The cost is handled through our Office 365 license, so I have yet to be able to compare it directly with other tools in its class."
"It's affordable. It's cheaper if you have an Office 365, E5, or E3 subscription because everything is there."
"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."
"The product is offered as part of a Microsoft standard bundle. The pricing can be competitive to Airwatch, and Maas360."
"For organizations that are a Microsoft shop, the pricing is compelling."
"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."
"Microsoft Intune is included in the E5 license at no additional cost."
"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."
"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."
"I am using the free version of TeamViewer. There is a subscription fee to use the premium features."
"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."
"The pricing is a little bit on the higher side."
"The price of the license could be less expensive."
"I used the free version of TeamViewer."
"The version of the solution we are using is free."
"It has probably saved us several thousands of dollars because we have quick access anywhere. We don't have to worry about finding people onsite or arranging conference calls. We also save time and money with it because we don't have to send somebody onsite to troubleshoot."
