TeamViewer is a comprehensive digital workplace platform used by more than 660,000 customers globally for remote access, IT support, endpoint management, and augmented reality-powered workflows. Founded in 2005 and headquartered in Göppingen, Germany, it operates on a freemium model — free for personal use, paid licenses for commercial use — and achieved EUR 768 million in revenue in 2025. TeamViewer's zero-configuration approach connects through firewalls without manual port forwarding via relay servers and peer-to-peer routing. In 2025, TeamViewer launched TeamViewer ONE, a unified platform combining remote connectivity, Digital Employee Experience (DEX), RMM, and AI-powered tools. Understanding its session types (attended vs. unattended), security layers (end-to-end encryption, two-factor authentication, conditional access), and enterprise capabilities (mass deployment, multitenancy, agentless OT access) transforms TeamViewer from a screen-sharing tool into a strategic IT operations platform.

Table 1: Connection Types and Access Modes

How a session is established determines what permissions are needed and how much configuration is required upfront. The key axis is attended vs. unattended: attended sessions use one-time passwords and require someone present, while unattended access ties a device to an account for anytime connectivity.

Type	Example	Description
Attended Access	Partner enters ID `123 456 789` + password → Support session starts	• One-time remote support where both parties are present • temporary password generated per session • ideal for troubleshooting end-user issues without pre-configuration
Unattended Access	Device assigned to account → Access anytime with account login → No password prompt	• Remote access without user intervention • requires device assignment to TeamViewer account • enables 24/7 access for server maintenance or personal computers
QuickSupport	End user downloads `TeamViewerQS.exe` → Runs without installation → Generates temporary ID	• Lightweight executable for spontaneous support sessions • no installation or admin rights required • automatically deleted after session • perfect for customer support where installing software isn't feasible
Full Client	Install `TeamViewer_Setup.exe` → Configure as service → Enables incoming/outgoing connections	• Complete installation providing both controller and host capabilities • runs as Windows service for unattended access • supports all features including file transfer, VPN, and terminal
Host Module	Deploy `TeamViewerHost.msi` via GPO → Device auto-assigned → Accepts only incoming connections	• Dedicated receive-only client for managed devices • minimal UI • ideal for servers or kiosks • reduces attack surface by disabling outbound connection features
Easy Access	Set password on device → Connect by ID without password prompt → Account-based trust	• Simplified authentication for frequently accessed devices • eliminates repetitive password entry • device must be in account's computer list
LAN Connection	Both devices on `192.168.1.0/24` → Direct peer-to-peer → No relay server	• Optimized local network connection • bypasses internet routing for lower latency • auto-detected when devices share subnet • improves performance for high-bandwidth tasks
Wake-on-LAN	Configure WOL in BIOS + TeamViewer settings → Send magic packet → Device powers on remotely	• Remotely power on sleeping/shutdown devices • requires BIOS support and network configuration • TeamViewer delivers WOL packet through relay • essential for energy-saving IT infrastructure
Session Invitation Link	Generate link in app → Send via email → Recipient clicks → Browser-based connection (no install)	• Web-based connection method • user downloads QuickSupport via secure link • link expires after use or timeout • shows provider name + location to prevent scam abuse
Agentless Access	Tensor configured → Connect to PLC/HMI → Control OT device → No software installed on device	• Tensor feature for operational technology (OT) environments • connect to PLCs, HMIs, and legacy industrial systems without installing an agent • enforces zero-trust with granular access controls and full audit logging • bridges IT/OT security governance gap

Table 2: Remote Control Features

Once connected, TeamViewer's session toolkit covers everything from full screen sharing to annotating the remote display. Knowing which features are available in the session toolbar — and which require paid tiers or specific configurations — prevents surprises during live support.

Feature	Example	Description
Screen Sharing	Connect to remote PC → See live desktop at 60 FPS → Control mouse/keyboard inputs	• Real-time desktop streaming with adaptive quality adjustment • supports multiple monitors • keyboard shortcuts mapped between systems • optimized codec reduces bandwidth

Table 3: Device and Computer Management

Organized device management is what separates ad-hoc remote access from a scalable IT operation. Device groups, policies, and custom fields let administrators build a structured inventory that scales from a dozen devices to tens of thousands.

Feature	Example	Description
Device Assignment	Install TeamViewer Host → Sign in → Device appears in "Managed Devices" list	• Link devices to account for persistent unattended access • assigned devices accessible without ID/password entry • devices organized in hierarchical groups

Table 4: Security and Access Control

TeamViewer's security model is multi-layered: encrypted transport, strong authentication, policy-based feature gates, and behavioral controls each address different threat vectors. For corporate deployments, mandatory 2FA and conditional access policies are non-negotiable baselines.

Feature	Example	Description
End-to-End Encryption	Session encrypted with AES-256 → Keys exchanged via RSA-4096 → MITM attacks prevented	• 256-bit AES for data, 4096-bit RSA for key exchange • zero-knowledge architecture — servers cannot decrypt session content • compliant with GDPR, SOC 2, ISO 27001
