K2 Cloud Secure Data Access (SDA) enables you to access your traditional, on-premises line-of-business systems from K2 Cloud applications without the need to open access within the firewall, place systems outside the firewall, or create VPN connections. Connections to your K2 Cloud tenancy originate from a network appliance deployed within your private network and are secured by an SSL-based, encrypted and exclusive connection between your on-premises environment and your tenancy.
