Feature Comparison

TeamViewer Germany GmbH has been a great tool for secure remote access for more than a decade, known for its extensive user base.

While ISL Online is lauded by IT teams and professionals for its simple, cost-effective, and highly secure remote desktop solutions with unique licensing.

1. Licensing Model and Cost Structure

The structure of the paid plans is a major differentiator, with ISL Online offering a model that is often considered more straightforward and potentially more cost-effective for large teams.

  • ISL Online: Offers highly flexible and unique features, including an all-inclusive licensing model primarily based on concurrent users, which allows for unlimited users and unlimited devices (subject to a fair usage policy for the number of unattended machines). It also offers a “Pay Per Use” option.
  • TeamViewer: Offers a tiered subscription structure with auto renewal, often limiting the number of licensed users and the maximum number of unattended devices that can be managed, though it has a well-known free for personal use option for single users supporting family remotely.

2. Deployment Flexibility and Private Network

ISL Online provides a unique solution for organizations that need maximum security and full control over sensitive information.

  • ISL Online: Is a secure remote access solution that offers both a cloud license and a Self-Hosted (Server License) or private cloud option. This allows organizations, especially those in regulated industries like health care, to install the system on their own network, ensuring all sensitive information remains on-premises.
  • TeamViewer: Primarily provides its service via its cloud platform, which offers easy access and regular updates. While it has options for enterprise-level deployments, its main offering is cloud-based, and it lacks the simple, explicit on premises installation option of ISL Online for a complete private network setup.

3. On-Demand Remote Assistance

Both remote desktop solutions excel at providing quick, instant support to end users and customers globally.

  • TeamViewer: Simplifies connection via the TeamViewer ID, which the support user provides to the remote user. This is a key feature seen in the TeamViewer remote control app that facilitates easy access for resolving issues.
  • ISL Online: Offers quick connection methods such as a session code or session links (often sent via email or through their free Live Chat integration), making it extremely easy for the client end to receive support with the ISL Light client.

4. Unattended Access and Management

The ability to maintain unattended devices for remote maintenance and support is essential for IT teams.

  • ISL Online: Provides ISL AlwaysOn for unattended remote computers. It’s designed to be a vastly superior solution that allows IT professionals to manage and remotely control devices with admin rights, and the simple installation of the client machines is highly rated in ISL Online review feedback.
  • TeamViewer: Offers unattended access by setting a permanent password for the remote device. TeamViewer users can organize their remote desktop contacts, but some users find the complexity of device limits a challenge for managing a large number of unattended devices.

5. Security and Advanced Security Features

Maximum security measures are integrated into both remote access software solutions to protect connections and sensitive data.

  • ISL Online: Provides advanced security features, including AES 256-bit end-to-end encryption and two factor authentication (2FA). Its highly customizable security settings are suitable for regulated industries.
  • TeamViewer: Also offers strong security with end-to-end encryption and two factor authentication, ensuring secure remote access. The company TeamViewer Germany GmbH utilizes incessant verification for the TeamViewer client connections.

6. Cross-Platform Compatibility and Mobile Device Support

Providing support across multiple operating systems, including mobile devices, is a critical feature for a modern support solution.

  • TeamViewer: Features extensive multi-platform support across all major operating systems (Windows, Mac, Linux) and excellent mobile device support for Android phone and iOS devices, enabling technicians to remotely control a wide range of devices.
  • ISL Online: Also offers strong mobile device support, allowing users to remotely control remote devices and provide remote assistance to Android and iOS devices, with its ISL Light app available across all major operating systems.

7. Augmented Reality (AR) and Integrated AI

TeamViewer has expanded its offerings into the physical realm using innovative technology like augmented reality.

  • TeamViewer: Has key features like augmented reality via TeamViewer Frontline (e.g., vision picking) to assist with logistics processes and field support, making life easier for technicians. It is also incorporating AI capabilities as seen in the TeamViewer Remote control app.
  • ISL Online: Focuses its feature set on optimizing the core remote desktop solution and providing superior customer support tools like its integrated Live Chat, without the specialized augmented reality modules.

8. Administrator Rights and Full Control

For IT professionals to provide remote support and resolve technical issues, the ability to gain full control and administrator rights is essential.

  • ISL Online: Offers an administrative mode, allowing IT professionals to send a command to reboot the remote computer and resume the session, or interact with UAC prompts to gain administrator rights for installing software on the users machines.
  • TeamViewer: Allows the support user to interact with UAC prompts and perform system-level tasks to gain control, which is standard functionality expected of professional remote control software.

9. Collaboration and Communication

Efficient communication tools within the remote support session enhance customer satisfaction and speed up resolving issues.

  • ISL Online: Integrates communication tools directly, including chat support and the unique feature of escalating a live chat session to a full remote desktop connection with a single click.
  • TeamViewer: Features a built-in text chat, video conferencing, and the ability to invite multiple teamviewer users to a support session for seamless collaboration and peer support.

What to Look for When Choosing a Remote Access Tool?

When picking a remote access tool, consider these points:

  • Speed: Does it feel fast and smooth?
  • Ease of Use: Is it simple to set up and use?
  • Security: Does it protect your data well?
