What is Terminal Emulator Software?
A terminal emulator is a software application that replicates the functions of a traditional hardware terminal, enabling communication with mainframes and servers. Instead of relying on outdated physical terminals, organizations can use emulators on PCs, tablets, or web browsers to access host-based applications.
Key features of terminal emulator software include:
- Support for multiple protocols (e.g., SSH, Telnet, TN3270, VT100)
- Cross-platform compatibility (Windows, macOS, Linux, Android, iOS)
- Security enhancements with SSL/TLS encryption and multi-factor authentication
- User-friendly interfaces with customizable layouts
- Cloud and web-based access for remote employees
Competitive Landscape
The market is moderately fragmented, with vendors focusing on innovation, user experience, and security features. Key players include:
- Micro Focus (Reflection, Rumba)
- Attachmate (Extra! and Reflection)
- Rocket Software (BlueZone, Passport)
- Ericom Software (AccessNow, PowerTerm)
- Netsarang Computer, Inc.
- Cybex / Avocent (Secure Terminal Emulators)
- Simon Tatham’s PuTTY (Open Source)
These companies are investing in cloud-native, browser-based, and mobile-friendly emulators, ensuring compatibility with modern enterprise IT ecosystems.
