Arca Noae brings OS/2 into the 21st Century

Global. With a worldwide virtual and physical presence, through our network of strategic and consulting partners, Arca Noae is here to support enterprises from large to small, as well as individual users. Companies relying upon OS/2 usually do so for critical infrastructure operations and cannot risk losing such a vital piece of their overall technology. However, these same enterprises often find themselves at a loss for talent and hardware upgrade recommendations. Arca Noae knows this and has answers.

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.
