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
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

"We can manage and standardize security across your environment, identify problems, receive alerts, and so on. That's its purpose, and that's also why it's so good."
"Microsoft Intune is easy to use, and it is able to enforce policies towards multiple devices. It is able to bring multiple classes of devices into the same security posture. I found that very useful."
"Given all of the factors and things to consider, including features and cost, I would say that Intune has a slight edge over competing products."
"It is very easy to use; it has a very easy interface."
"The ability to block and erase remote devices is valuable to us, especially when those devices are lost."
"The feature that we need occasionally but is really important is the ability to remotely wipe a device, control it, and perform similar functions."
"Intune is the best tool going forward because everyone is moving to the cloud."
"As an IT administrator, I appreciate Intune's ability to implement granular device-level policies for our organization's employees."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"The most valuable feature is safety."
"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 and it provides a single platform for various challenges we face in IT."
"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 personally really appreciate the file transfer feature as it is really easy to use."
"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."
"Without ISL Online, I would not be able to work from home."
"The new two-factor authentication is a very good addition to security."
"The solution is very stable, and we've never had a problem with it."
"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."
"The most valuable features of TeamViewer are the ability for administrators to lock the remote systems, simple connections, and easy login access."
"I am satisfied with TeamViewer, and its performance."
"I don't know of any performance problems with TeamViewer - generally, it's a stable product."
"TeamViewer has a lot of options for deploying the Hosts, where you can mass deploy them very easily, and you can pre-configure them."
"This product is very simple to use and you can connect whether you are behind a firewall or not."
 

Cons

"Areas for improvement in Intune include expanding support beyond Samsung devices to accommodate other Android manufacturers like Redmi and Motorola."
"There is always a noise when you are going to manage any endpoint devices, and noise is definitely there with this solution."
"The documentation about the custom image setup could be better. Although Microsoft provides the steps to configure Intune or set up or deploy Intune, it doesn't have much information related to custom images. If you ask, "how can we deploy the custom image?" There is no information. The steps they mention ask you to connect to your on-premises environment or create your own image on the cloud itself once there is connectivity. But I needed to go to multiple websites to get all this information. I had to figure out how to upload the custom image if you want to use the on-premise custom image for Cloud PC. If you have the proper subscription, you must have the right access, like global admin or owner. Then you can add your custom image to that. There are no steps mentioned over there. Microsoft Intune doesn't have Chrome browser support. I would like to have that support because they will want it if we pitch the product to clients."
"We have spoken to the technical support on a few occasions. They have only ever provided us with minimal information."
"When pushing anything from Microsoft Intune, the sync timing is 48 hours. While sometimes it takes 5 to 10 minutes, the official period given by Microsoft is within 48 hours, which can be time-consuming for policies, applications, or patches."
"I wish Microsoft would keep up with their documentation. They make changes so quickly to these platforms that they do not update the documentation properly in a timely manner."
"Currently, BitLocker does not support BYOD enrollment, which is a product limitation."
"The generic answer to what can be improved is that I hope that the reporting needs to be a bit more interactive."
"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."
"There could be a section in the menu describing the new features and changes."
"They need to better advertise the features."
"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 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."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"We miss the possibility to communicate via head-set in ISL."
"Support for mobile devices from Linux has been missing since the Native client was rolled out."
"TeamViewer could work on performance latency in slower internet connections by optimizing screen refresh rates during remote sessions, especially when transferring large files or using graphics-heavy applications."
"The price is a killer for the amount I normally use it."
"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."
"In the next release, I would prefer to have a voice integration and collaboration feature to support multiple teams simultaneously."
"It needs to have proper authentication."
"It would be useful if the solution could facilitate more than one remote user accessing my desktop at a time."
"The security could improve in TeamViewer."
 

Pricing and Cost Advice

"It's bundled with Business Premium and an E3 license, which is beneficial. If you have to pay extra, it's pricey, but with the bundled package, it's acceptable. They recently increased the Business Premium pricing, which we don't appreciate. The price increase and yearly commitment are causing some problems for us."
"For Microsoft 365 E5 clients, cost is not an issue as this product is one of the benefits."
"It is reasonable for the features it has."
"As a partner, we always look for how we can generate more revenue from a consulting point of view, but I do not see any complaints from the customer side regarding pricing, so they are satisfied with it."
"Microsoft Intune costs about $7 per user per month, which is somewhat on the pricier end. That said, it's a reliable product, so it's fair."
"It's a bit expensive from a licensing perspective, especially as we look to have organizations with tenants across the globe."
"The price could be better."
"If you ask the accountant or the finance department, they'll tell you that it is way too expensive, but when I look at the cost and compare it with the value you actually get, it's more than fair."
"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 has multiple licensing options."
"We are not using the solution for commercial use therefore it is free to use."
"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 version of the solution we are using is free."
"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."
"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."
"There is no license needed to use TeamViewer."
"I used the free version of TeamViewer."
