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

"It has helped with compliance. It has helped to ensure that devices comply with the organization's policy. If they are not compliant and secure, they cannot access the resources."
"From my perspective, I appreciate the scalability in Microsoft Intune and the portal management, which is extremely intuitive and very simple to use."
"The main advantage is that Intune performs its intended functions effectively."
"The ability to send configurations to our systems is valuable, particularly as we don't have a regular Windows AD server. Our current environment doesn't have a Windows AD, which limits our ability to push GPOs. However, this is where the solution can step in and help us push policies."
"Microsoft Intune is a tool designed for enterprise customers to protect enterprise data from leakage or sharing."
"Intune's most valuable feature is its centralized management capability."
"It helps implement conditional access policies to restrict mobile users from accessing potentially dangerous emails."
"If a client is using a lot of Microsoft, it's a great product to have."
"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 code can be delivered in multiple ways, including an email with a link for an unattended connection."
"Good communication is a key to good business and ISL helps a lot."
"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."
"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."
"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."
"Remote desktop sharing is one valuable feature of the solution."
"The product is quite stable. The performance is good."
"It is a scalable product."
"Working with TeamViewer has made customer support work more efficient."
"This product is very simple to use and you can connect whether you are behind a firewall or not."
"TeamViewer has been one of the easiest, right off the bat products, that we have employed at the college. We have had no issues. It's been one of the easiest solutions to pick up."
"TeamViewer Business does a lot in the enterprise part and has many features that can be used in big organizations, and it is able to assist on the network side, monitoring, security side, and remote side, making it a good platform and solution to use."
"TeamViewer has positively impacted my organization because it has helped us in saving a lot of time, as the process of conveying instructions is much simpler now, and we are able to provide better online training to our new staff."
 

Cons

"Intune is a good product for UEM, which is helpful for Windows 10 management. However, for MAM, there is lots of improvement needed."
"The installation could be improved to be simplified."
"They should improve its compatibility with other operating systems such as iOS and Linux. It supports Linux but they still need to work on the iOS part."
"Improvements can be made by allowing server integrations since it is an area where the product currently has shortcomings."
"Sometimes, it takes time to synchronize the policies between the portal and the devices, you don't have a way to estimate how long it will take to deploy. You have some kind of gray area, where it can deploy in 30 minutes or three days."
"The feature that allows us to import the business application from the configuration manager to Intune is not very good at this time."
"It would be nice to have a location tracker for the mobile device management tool. I'm not sure if it exists but hasn't been configured or if it's missing, but we've been unable to utilize the location features."
"There are areas that have room for improvement in Microsoft Intune, particularly regarding integrations."
"There could be a section in the menu describing the new features and changes."
"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."
"It would be helpful if they had iSupport for supporting Apple phones."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"Updating the program could be improved. When they're pushing updates, you don't really know that there's an update available."
"We miss the possibility to communicate via head-set in ISL."
"They should improve the integrations with other incident management software to be able to send the link directly from these platforms."
"One thing I have noticed is that TeamViewer does not work so well when the machine you are trying to connect to remotely is not running the same version as your machine."
"In a future release of TeamViewer, they should improve password access."
"It needs to have proper authentication."
"The price is a killer for the amount I normally use it."
"The one area which needs improvement for both the standalone and enterprise versions would be inter-operability between versions."
"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."
"Voice communication and screen communication or face-to-face communication could be improved."
"The security could improve in TeamViewer."
 

Pricing and Cost Advice

"Microsoft Intune is pretty reasonable. We have difficulty with Azure, which is probably why we have not put many assets in Azure. Everything we put there is very expensive."
"It comes with the E5 plan. We bought the E5 plan from Microsoft."
"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."
"There is a license needed for this solution and it is either included in one of the enterprise license agreements. Microsoft licensing is a mathematical institute, it could be quite complex. We tend to ask specialized organizations to research what the most profitable way it would be for us to use licenses in the organizations."
"Intune comes with the licensing that is common for large organizations. However, Microsoft has recently released many add-ons that are very expensive, especially for large organizations or corporations."
"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."
"I rate Intune five out of 10 for pricing. It's expensive."
"While Microsoft charges for actual usage, it lacks discount options."
"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."
"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."
"There is no license needed to use TeamViewer."
"TeamViewer pricing is reasonable... The simultaneous controller licensing model of TeamViewer - compared to LogMeIn’s controlled Host licensing model - seems to benefit us so far. We’re currently saving about 30 percent on licensing cost... The savings from licensing have been eaten up by the soft costs involved in dealing with and working around TeamViewer’s deficiencies in allowing granular control by multiple controllers, and the issues with the various settings that are missing on the macOS Host."
"The cost is in the thousands of dollars per year."
"The solution's pricing is reasonable."
"We are using the standard free version of TeamViewer."
"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."
