Centralized device management has automated onboarding and improves remote security compliance
One thing I feel Microsoft Intune could improve is troubleshooting visibility. In many cases, when a policy or application deployment fails, the error messages are a bit generic. So, admins still spend time checking logs manually or testing on devices one by one. Compared to the simplicity of deployment, troubleshooting sometimes feels less mature. I also think reporting and real-time monitoring could be stronger. The dashboard gives useful information, but in large environments, many teams still depend on additional tools or scripts for deeper reporting and analytics. If I had to focus on one area first, I would probably choose troubleshooting and reporting. Deployment through Microsoft Intune is generally straightforward, but when something fails, identifying the exact root cause can still take more time than expected. Error messages are sometimes too generic, and admins often have to dig through logs, sync status, or multiple portals to understand what actually happened. I think user experience and policy management could also improve further. Microsoft Intune has become much better over the years, but sometimes the admin portal still feels fragmented because certain configurations open in different sections or redirect to older interfaces. For new admins, especially, it can take time to understand where everything is located. Another thing is policy conflict handling. In larger organizations, multiple device policies, compliance rules, and configuration profiles can overlap. When conflicts happen, the visibility is not always very clear, so admins spend time figuring out which policy actually won or caused the issue.

Secure web access for guest users has transformed how we protect servers without device agents
Apache Guacamole can be improved as the documentation is really okay. It's written in very good detail. However, there's a problem in that it is written in too much detail and doesn't take you step-by-step. We did have some minor issues, such as there was some gap in mentioning how to install it and how to make and compile the file which they have posted on the repository. We had to figure it out, and once we got that knowledge, we were able to speed up our process. I think that the documentation wasn't that well written. There were gaps in it. It was well written but not written step-by-step. They can improve Apache Guacamole's UI. We didn't use their UI and use our own UI instead, but their UI can be improved. Simple is also good but it can be improved.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"A valuable feature is user enrollment, where users can enroll their devices in their organizations themselves."
"Remote Wipe and Autopilot is one of the best features."
"It is a helpful tool to manage BYOD policies."
"Microsoft Intune is cost-effective and easy to use, so I can recommend it."
"Endpoint Manager has been around the longest, it's survived, it's matured and it's the top dog in general."
"It is very easy to use. It has a very easy interface."
"The solution’s most valuable feature is its ease of use."
"Microsoft Tech Support is good, providing solid support."
"Apache Guacamole thus far has been both open source, simple to use, easy to set up, quick, and it makes it easy for me to provision systems as well."
"Apache Guacamole is really easy to use."
"I'm using Apache Guacamole as a gateway."
"One of the advantages is that it helps to simplify and fasten the processes, so the workflow goes much faster."
"Apache Guacamole has positively impacted our organization because we are able to give access to Windows instances easily."
"I believe Apache Guacamole is the best option on the market at the moment because it is free."
"Apache Guacamole helped us cross that boundary, and leveraging that technology, we were able to expand our product surface area and the customers we can access."
"In my opinion, the best features that Apache Guacamole offers are being free, providing a web-based remote Windows session service, and allowing remote printing of files."
"The most valuable feature is safety."
"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."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"Without ISL Online, I would not be able to work from home."
"I personally really appreciate the file transfer feature as it is really easy to use."
"We can also monitor our systems at any time from practically anywhere."
"The solution has a lot of features. It does what it is made to do and that's all we can ask for, really."
 

Cons

"For migrations, sometimes we experience some issues with OS deployment and the user experience side."
"The biggest challenge is that the admin portal can feel complex, especially for administrators who are new to the platform."
"There is no catalog for mobile access management (MAM) security."
"At this time, I do not have any areas for improvement. I have heard about some downtime, but I am not in the local IT team."
"A detailed device diagnostic feature is missing. Also, operating system deployment and imaging are missing."
"Microsoft Intune could be improved in several areas."
"Yes, there are a couple of issues with stability."
"Microsoft needs to strategize its licensing structure. When using Microsoft Intune, we bought a small scale of controls, only controlling part of the devices, though Microsoft Intune can do much more. The Intune Suite offers more features, allowing extensive integration with either internal or cloud environments without requiring third-party licensing. However, each feature has a separate license, making logistics and cost management difficult if not strategically bundled together."
"There is no customer support for Apache Guacamole."
"I gave it a nine because some very advanced features such as session recording and clipboard functionality are still not available on Apache Guacamole, though they are available on Citrix."
"The solution's USB redirection could be improved."
"I think that the documentation wasn't that well written."
"There should be good documentation regarding GUI customization. Even though I can try customizing the GUI, the documentation is not comprehensive."
"I have faced some difficulties when copying and pasting data at points, but apart from that, the stability is great and cursor movements are in real-time with very low latency."
"I think that in the visual interface it would be interesting to make it easier to change the background."
"In my opinion, Apache Guacamole can be improved with USB access, a native client, and enhanced browser access, which would be beneficial."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"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 be able to access and manage all brands of smartphones."
"There could be a section in the menu describing the new features and changes."
"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."
"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."
 

Pricing and Cost Advice

"If you're ever going to buy an Office 365 environment, then pricing is reasonable given all that it does, but if you're not, then you might find the pricing expensive."
"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."
"Pricing can be improved."
"Its price is in the medium range. It is acceptable because you're paying for the features. I am not aware of any additional costs."
"Microsoft offers some licensing where it's included at no extra cost when customers are already using the licenses. In such a case, it's a really good value. If you have to buy the licensing for it, it's probably on par with other solutions. It isn't substantially more or less expensive. The great thing is that it is included in some of Microsoft's licensed packages. So, some customers don't have to spend additional money for it. Typically, most providers that support Intune do charge a management fee of some sort or some fee. Certainly, we're no exception."
"The licensing is on a yearly basis."
"Intune's pricing is reasonable considering its benefits and the high costs it helps avoid."
"The Intune license model is costly."
Information not available
"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."
