1. Remote Access and Remote Control
TeamViewer: The TeamViewer remote control app lets you access and remotely control any computer or other devices through a simple TeamViewer ID and password. You enter the partner ID in the Control Remote Computer section and you are in. Multi-monitor setups are handled automatically with intelligent scaling across all screens.

ISL在线: ISL Online allows technicians to tap into client workstations from thousands of miles away for fast remote assistance. The session link is generated 即刻 and shared with the remote user via a browser window or email. ISL Online reviews consistently praise how extremely easy it is to connect without complicated session codes.
⚠️ 警告: TeamViewer may flag accounts that appear to use the free version for commercial purposes. If you support users beyond friends and family, you need a paid commercial license.
2. Security and Two-Factor Authentication
TeamViewer: TeamViewer uses AES 256-bit encryption and two-factor authentication on every connection. The AI Suite adds real-time threat analysis and session monitoring. Users value the security features integrated within TeamViewer, which builds trust — especially for IT teams handling sensitive data on remote devices.
ISL在线: ISL Online matches AES-256 encryption and two-factor authentication. It adds granular device permissions, administrator rights control, and compliance with international security standards. Its 22-year breach-free record and maximum security posture make it the top pick for health care and regulated industries handling sensitive information.

✅ 测试结果: Both platforms passed standard encryption and two-factor authentication checks. ISL Online’s private cloud option and 22-year breach-free record give it a clear edge for organizations in regulated industries.
3. Unattended Access
TeamViewer: TeamViewer can run as a Windows system service, giving permanent unattended access to servers and headless devices. You can access unattended devices any time without anyone present. This is one of the most-used features seen in the TeamViewer platform among IT teams managing remote servers.

ISL在线: ISL Online uses the ISL AlwaysOn app to provide access to unattended remote computers at any time. You install ISL AlwaysOn on target machines once, then connect from any browser window or the ISL Light app. Unattended machines are listed in the admin panel for easy access.
⚠️ 警告: ISL AlwaysOn must be pre-installed on each unattended computer before you can connect remotely. Plan your installation before rolling out to a large fleet of remote devices.
4. Screen Sharing and Session Recording
TeamViewer: TeamViewer offers full screen sharing across all connected operating systems. Session recordings are stored locally or in the cloud. TeamViewer’s Session Insights feature uses AI to generate automatic summaries and documentation at the end of each remote support session — saving IT teams significant time.
ISL在线: ISL Online provides reliable screen sharing and session recording for all remote sessions. Session recordings are stored with access password protection. Records can be used for compliance 报道, training, or resolving disputes about what happened during a support session.

5. AI Capabilities and TeamViewer Frontline
TeamViewer: AI capabilities as seen in TeamViewer Frontline go far beyond standard remote support. TeamViewer Frontline supports augmented reality for guided workflows in industrial settings. It powers vision picking for logistics processes — where workers use AR headsets to receive real-time instructions during warehouse operations. The AI Suite also handles real-time troubleshooting analysis and resolution recommendations.

ISL在线: ISL Online does not currently offer AI-powered features or augmented reality capabilities. It focuses on reliable, secure remote desktop support rather than advanced 自动化. For IT professionals who need straightforward access and support tools, this is not a drawback — but teams that want AI-driven workflows will need to look at TeamViewer.
⚠️ 笔记: TeamViewer Frontline’s AR and vision picking features are designed for enterprise industrial use. They are not included in the standard Remote Access or Business plans. Pricing for Frontline is available on request.
6. 文件传输
TeamViewer: TeamViewer supports drag-and-drop file transfer with queued transfers during active remote sessions. You can move files in both directions between the local and remote computer without ending the session. Real-time chat during the session lets you keep the remote user informed of every step.
ISL在线: ISL Online includes an easy file manager for transferring documents and installing programs on remote computers. File sharing is available alongside audio and video calls and messaging during the session. The file manager interface is clean and user-friendly for both technicians and end users.

7. Administration and User Management
TeamViewer: TeamViewer’s management console lets IT teams manage multiple accounts, set user permissions, and track all remote sessions from a central dashboard. Subscription plans vary based on the number of users and concurrent sessions. Adding more users or sessions raises the monthly cost through add-ons.

ISL在线: ISL Online’s administration tools cover user management, device permissions, session tracking, and reporting. The Standard plan adds mobile device support and user management tools. Premium adds SSO/SAML for enterprise environments. Crucially, unlimited users are included on all ISL Online plans without escalating fees.

8. 移动设备支持
TeamViewer: TeamViewer supports remote control of Android phones and other Android devices directly from a desktop. Full control of an Android phone is possible with administrator rights granted on the remote device. iOS devices support view-only sessions due to Apple’s system restrictions. Mobile devices are managed alongside computers from the same interface.
ISL在线: ISL Online provides full mobile device support for Android and iOS devices on the Standard plan and above. You can offer support to users on iOS devices and Android devices without switching tools. Standard customization options let you brand the mobile client for your business.
💡 提示: If mobile device support is critical to your IT operations, check which ISL Online plan tier includes it before purchasing. The Starter plan does not include full mobile support — you need Standard or above.
9. 定价和成本
Here is how the pricing structure compares side by side.
| 计划层级 | TeamViewer | ISL在线 |
|---|---|---|
| 自由的 | ✅ Personal non-commercial | ✅ 15-day trial period |
| 入门级 | 每月 18.90 美元 | 每月 16.90 美元 |
| Business / Standard | 每月 42.90 美元 | 每月 34.90 美元 |
| 优质的 | 不适用 | 每月 54.90 美元 |
| 企业 | 风俗 | 每年约 24,000 美元 |
| 按次付费 | 不适用 | $125/500 minutes per year |
TeamViewer: TeamViewer’s pricing structure includes numerous add-ons that can quickly increase costs compared to ISL Online’s straightforward model. The Remote Access plan at $18.90/month covers one user and one session. TeamViewer subscriptions automatically renew unless auto-renewal is turned off — a critical detail for single users on annual plans.
ISL在线: ISL Online’s all-inclusive licensing model gives you unlimited users and managed devices on every plan. There are no escalating fees per seat. The Pay Per Use option at $125 per 500 minutes per year works well for low-volume users who only need occasional remote support.
💡 测试结果: ISL Online saves money for teams with more than two technicians. TeamViewer’s per-user add-ons make it more complex and expensive to scale.

我们的评测没有涵盖的内容
This comparison focused on individual IT professionals, small teams, and mid-size IT environments. We did not evaluate enterprise-level deployment at scale, custom API integrations, or how either tool performs for large logistics processes using TeamViewer Frontline’s full AR suite. If you are managing 100+ remote devices across multiple countries, your experience with pricing and support will likely differ from what we have covered here. Always test both tools during the trial period before committing to a license.
