Cyber security is at the heart of Sigma Net, which incorporates a firewall and Virtual Private Networking between the vessel and the internet plus methods to regulate internet access, including rejection of update services to Windows or mobile devices.

Voice calling across multiple satellite equipment is simplified via Sigma Net’s integrated VoIP server, allowing a caller to choose the outbound call route via a prefix. National numbers can also be allocated, allowing for calling from shore to a vessel. Feature and performance enhancements are automatically applied, ensuring that the Sigma Net’s software is always kept up to date.

Sigma Net offers flexible crew services, including pre-paid PIN-based BYOD (Bring Your Own Device) internet and voice calling services, allowing for simplified voucher generation and management from shore. Sigma Net provides managed network segmentation between business critical, crew or M2M networks at the remote location. The cloud-based Sigma Net Portal brings a vessel or remote site closer to IT management through its innovative and secured portal.
