Arca Noae brings OS/2 into the 21st Century

Providing solutions to bring OS/2 in line and on par with today’s data encryption standards, fostering new web browser and networking technology for the platform, secure authentication and file transfer across the office or home LAN and across the internet, Arca Noae is here to support your security needs. we put those principles into practice on our websites and in our online store, always vigilant about the data with which we have been entrusted. Need a security audit?

Leader. Arca Noae maintains close ties to the OS/2 community, sponsoring new development for the platform and engaging with users and systems administrators to better understand their needs. Arca Noae principals and engineers regularly speak at OS/2-focused events, and are involved with online discussions, assisting other developers and users beyond company borders.
