The devices, to be unveiled by RSA Security this week, offer the same level of security used by larger firms to small companies with mobile workers who need to log into company systems.
Smaller companies have been deterred from investing in secure authentication for their staff because of the high maintenance costs of the equipment and the difficulty of configuring their systems to take secure tokens.
RSA claimed to have solved these problems by bundling the technology into a plug-in unit that requires little configuration and system testing once installed.
"It takes minutes to do the initiation and set up. It offers ease of deployment, ease of management and low cost of ownership," said product manager Gary Wood.
RSA believes smaller firms will want to move towards two-factor authentication, which uses a secure token to generate one-time passcodes, as they grapple with compliance regulations.
