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

"Mobile device management is most valuable."
"The most valuable includes managing everything from a single console."
"The most valuable feature of Intune is the ability to reset a lost device and remove all the data."
"The Autopilot feature is fantastic; it is a Microsoft product, so it deals best with Microsoft operating systems, but it can integrate with iOS, Mac OS, Linux, and Android."
"Microsoft Intune has been a time saver and reduces the time and effort IT admins have to invest."
"Overall, the stability is good."
"The most useful features in Microsoft Intune are the policy enforcement and conditional access. These features make our operations easier from a company perspective."
"Microsoft Intune policies, remote wipe, and using corporate and private profiles are valuable features, but MFA is the most valuable feature as it ensures that the end user is authentic."
"ISL Online is easy to use and it provides a single platform for various challenges we face in IT."
"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."
"We can also monitor our systems at any time from practically anywhere."
"Good communication is a key to good business and ISL helps a lot."
"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."
"Overall, we are very pleased with this solution, for us, it simply works 99.9% of the time."
"Setting up the solution is easy and there's no maintenance involved."
"From my perspective, the most important is the login."
"This is a unique solution that is very easy to install."
"The most valuable feature of TeamViewer is user-friendliness."
"The best feature is the remote access and being able to control another person's computer when you're showing them something, or teaching them how to do something during training, or fixing a problem they're having."
"The product is really straightforward and completely easy to implement."
"The real-time access has been excellent."
"The most valuable feature of TeamViewer is the ability to remote into another device."
"Remote desktop sharing is one valuable feature of the solution."
 

Cons

"There is improvement needed in integrating with the installed Office solutions versions, such as Office 2019."
"If you're looking forward to deficiency, I'd say that the Endpoint Manager support at the lower levels is poor."
"The scalability could be improved, and like most other MDM products, Intune is good but not 100% there yet."
"There are a few security features that are not available in Microsoft Intune, when compared to other products."
"Microsoft Intune could be faster with client to server communication. Whenever I push something, it takes time; sometimes it takes more than one hour to deploy on the Windows side."
"The synchronization of devices takes a significant amount of time, between 15 minutes and two hours. Microsoft should work on reducing this sync time to improve efficiency."
"For an existing customer who has an SCCM, it would need to be upgraded to an MECM first before I can introduce Microsoft Intune."
"Although Intune is from the same provider, its integration with other Microsoft products, like Microsoft Defender or Microsoft Purview, could be improved."
"It would be helpful if they had iSupport for supporting Apple phones."
"It would be easier for me to implement them and consolidate ISL with other systems in our network if I knew beforehand."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"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."
"They need to better advertise the features."
"I would like to be able to access and manage all brands of smartphones."
"There have been times during updates when something wouldn't work quite right, however, they are quick with updates and quick with fixes."
"Some of the additional features, like the meeting stuff, is making it too cluttered."
"If they could figure out a little better solution for the iOS stuff other than just a screen share, even though it's an Apple thing, and Apple doesn't like to give up control of their devices. If they ever got to that point, and I could manipulate an iPad or iPhone, that would be awesome. Since we have a bunch of iPad users who are struggling with doing different things, it would be nice to be able to just jump on and actually show them, "Here, do this, this, and this." Similar to what we do with the laptops, e.g. for training."
"We would like to have an option to create subgroups, where only members of the subgroup have access to the other members."
"It needs to have proper authentication."
"I didn't like the fact that you had to install a client for remote support. If you didn't install the client, you were very limited in terms of what you could do."
"TeamViewer can improve by making the interface more user-friendly. It looks very basic, they can make it more modern and easy to use."
"Sometimes it lags. They need to optimize it a bit."
"Customer support for TeamViewer is quite slow. They do reply, but the reply timing is more than forty-eight hours, which is not acceptable for any service industry."
 

Pricing and Cost Advice

"I don't have any problem as far as cost is concerned. It is bundled with our license."
"It's affordable. It's cheaper if you have an Office 365, E5, or E3 subscription because everything is there."
"I would rate the price a four out of ten with ten being the most expensive."
"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."
"While I don't have access to high-level financial information, I believe we have achieved lower costs with this implementation."
"It's reasonable. They're not giving it away, but it's reasonable."
"It is cheap, but as compared to Google, it is costly. Google is cheaper, but quality-wise, Microsoft Intune is better."
"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."
"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."
"The version of the solution we are using is free."
"It would be nice if it is cheaper."
"It does what I need it to do but I think it's expensive. It wasn't easy for me to get approval from the company to get it... It's costing us about $700 a year, per license."
"We are using the free version of TeamViewer."
"The solution has a pilot feature that is expensive. The overall price of the solution can be cheaper."
"There is no license needed to use TeamViewer."
"...it will cost you $1,500 to $1,600 a year, but when I think of how much work I do through TeamViewer..."
"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."
