Centralized device management has transformed security and streamlined remote provisioning
One area where Microsoft Intune can improve is the user interface. Sometimes the portal feels a bit complex and not very intuitive, especially for new users, and it can take time to find specific settings. Another point is troubleshooting. While logs are available, the diagnostic policies and sync issues can still be time-consuming and not very straightforward. I also feel that reporting could be more detailed and customizable. The built-in reports are helpful, but for deeper insights, I often need to rely on additional tools. Overall, it is a strong solution, but improving usability and troubleshooting experience would make it even better. While Microsoft Intune works very well within the Microsoft ecosystem, the integration of some third-party tools could be smoother and require less customization. Support is another area that could improve, as sometimes response times can be slow, and resolving complex issues may take longer than expected. In terms of features, I think more advanced automation and built-in remediation options would be helpful since common issues can be fixed automatically without manual intervention.

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.
Begaya Morris - PeerSpot reviewer

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 ability to manage devices over the cloud is a big benefit, as devices now receive updates regardless of location."
"The user experience is good; we could work and deploy many controls through Microsoft Intune."
"Conditional access has helped 3M tailor and enforce our security policies in the mobile space."
"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."
"Microsoft Intune has had a very positive impact on our organization, especially in terms of security and efficiency."
"We have definitely seen a good return on investment with Microsoft Intune, as it saved us a lot of time on manual tasks and reduced the need for extra tools, so overall costs went down as well."
"The valuable feature of this solution is its ease of use."
"Comparing this to having an endpoint management solution, the efficiency gain may be up to 80%."
"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."
"It's much easier to connect with other services, and it's working great. We haven't had any problems."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
"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."
"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."
"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."
"I would happily recommend this product for both personal and commercial reasons because of its price and also because of its ease of use."
"It’s so great for when you need to provide remote support, allowing us to troubleshoot in real-time, with good configuration and structure, easy installation, strong stability, good scalability, and it isn’t expensive at all."
"Saves travel time, and wide support of platforms allows for a single solution."
"One of the best features of TeamViewer Business is the security and respect for privacy, since you can connect to a specific computer using a unique confidential code, ensuring that security and safety are maintained with no problems."
"It's worth every penny; I would recommend it any time."
"The most valuable feature is you do not need to know the Windows username and password to connect and see the staff screen."
"The most valuable feature of TeamViewer is its ease of use."
"Their tech support is really good."
 

Cons

"The current Intune reporting functionality could benefit from some improvements."
"The main differences between Intune and other products are, like I mentioned, in terms of the Mac. If the customers are majorly moving and adopting Mac laptops while they are using the Intune, they are leaving for other platforms, like Workspace ONE and vMOX."
"The technical support by Microsoft is not so good. We have to manage many things by ourselves and do not receive responses in a timely manner."
"Microsoft Intune's app deployment presents challenges for non-MSI and non-store apps, particularly EXEs, requiring the use of a Win32 wrapper tool and adding overhead to the process."
"Since the devices are configured over the Internet, whatever policy we apply from the compliance portal does not reflect immediately on the endpoint."
"Microsoft documentation is a bit hard to get around, so having more control over devices would be good."
"Lacking in features such as Wi-Fi and network security."
"Microsoft Intune's support for Mac devices is lacking and could be improved."
"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."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"There could be a section in the menu describing the new features and changes."
"They need to better advertise the features."
"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."
"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 performance could always be better."
"TeamViewer could improve by having a cloud version. Having the solution on the system could cause some cyber security concerns with data."
"TeamViewer could improve by adding support for other operating systems, such as Linux and CAKE."
"I can use up to three computers, but sometimes I have four. So, it would be nice to have at least four computers."
"There is a paid version of this solution with more features available. However, they should provide more free features to the user, such as factor authentication."
"I would like it if the trial version of TeamViewer allowed you to have a connection for much longer."
"The security could improve in TeamViewer."
"The connection and reconnection sometimes lag and can cause problems."
 

Pricing and Cost Advice

"Cost is not my department, but the product is included in the E5 license that we already pay for every user, so no additional cost is incurred."
"It's affordable for the protection it gives. There are no additional costs."
"The price is very reasonable."
"While Microsoft charges for actual usage, it lacks discount options."
"The cost of the license and the features are justified for myself as a technical person."
"Our Office 365 Business Premium license, including Office 365 and Intune Management, offers excellent value."
"Any bundle package, such as Security E3, covers multiple things, such as AAP, BitLocker, etc. If you go for them individually, they would be more expensive. Bundling makes the price more attractive and competitive."
"In terms of the product price and licensing costs, my company finds the product to be reasonably priced."
"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 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."
"The cost is in the thousands of dollars per year."
"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."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"We are not using the solution for commercial use therefore it is free to use."
"TeamViewer has multiple licensing options."
"The version of the solution we are using is free."
"We are using the free version of TeamViewer."
