SecureCRT vs. Putty — What's the Difference?

SecureCRT is a commercially available SSH and Telnet client that provides secure remote access, file transfers, and data tunneling for everyone from IT professionals to end-users. It supports a wide range of protocols such as SSH1, SSH2, Telnet, Telnet/SSL, and serial, with a robust set of features including session management, advanced security options, and scripting capabilities. Putty, in contrast, is a free and open-source terminal emulator, serial console, and network file transfer application that supports similar protocols but with a focus on simplicity and basic functionality.

Both SecureCRT and Putty are used to connect to servers, routers, and switches remotely, providing a command-line interface for system administrators and developers. SecureCRT's interface is more modern and user-friendly, with tabbed sessions and customizable menus, while Putty's interface is quite minimalistic, favoring function over form. SecureCRT also offers more robust security features like smart card support and the ability to store passwords and keys securely, whereas Putty has a simpler security model which is sometimes less secure because it stores session information in the Windows registry.

When it comes to automation, SecureCRT shines with its built-in scripting capabilities, which allow repetitive tasks to be automated using VBScript, JScript, or PerlScript. Putty lacks a built-in scripting feature, which means users often have to rely on third-party tools or manual processes to automate tasks. SecureCRT also provides the ability to manage and customize sessions extensively, with features like button bar for repeated commands, whereas Putty offers minimal session management capabilities.

SecureCRT provides an integrated file transfer capabilities with Zmodem, Xmodem, and Ymodem support built in. It also integrates with SecureFX, which provides more advanced file transfer features. Putty, on the other hand, requires a separate program called PSFTP or PSCP for secure file transfer, which can be less convenient for users who frequently move files between local and remote systems.

Overall, SecureCRT is targeted toward organizations and professionals who require advanced functionality and enhanced security, which is reflected in its pricing. Putty, meanwhile, is widely used by individuals and organizations that need a straightforward, no-cost solution for remote terminal services.
