Innovations at sea delivered with passion
Dualog was conceived on the shore of the Arctic Ocean. The company grew out of a research project in close collaboration with the world’s northermost university – the Arctic University. The focus was on providing robust software for reliable data communications in difficult waters. Unique expertise and arctic resilience gave birth to the company renowned for relentless focus on innovation.
Dualog enabled transmission of the very first email messages from fishing vessels operating on the edge of the polar ice fields. Constantly pushing the boundaries of technology, the company expanded to become a leading solution vendor to the global shipping industry.
Still evolving and growing, Dualog maintains intense customer focus, independence and agility. Being culturally diverse, uniquely competent and empathetic enables Dualog to stay in touch with customers and their real-life challenges.
We believe that sea and shore can be brought closer together. Our recognised solutions enable the seafarers to easily stay in touch with their families. It helps the shipping companies to improve its own business.
Dualog® Quota enables shipping companies to offer internet to the crew in a controllable manner. The service will help shape traffic according to company policy, ensure cost control and assure fair usage distribution. Paired with the free and award-winning CrewConnection™ App, seafarers gain full control of their data usage.
With Dualog® Drive, you can rest assured that files are handled in the most efficient manner. Dualog® Drive uses a global deduplication method where file patterns are identified and treated as chunks of data, effectively reducing the amount of data to be transferred. We also use state-of-the-art compression to minimise file sizes. The ability to resume transfers is a necessity when working under tough conditions.
Introducing Dualog® Protect – a better way to make your fleet safer. The Dualog® Protect service stops most malware, ransomware, trojan and phishing attempts, ultimately blocking unsafe or suspicious internet resources before any harm is done by monitoring all activity at the DNS-level.
Dualog® Crew Mail provides private email accounts for seafarers regardless of the communication equipment onboard. Crew details can be updated and distributed automatically from the Crew Management System to all vessels, minimising IT staff workload drastically. The service relies on the world-class capability of the Dualog Cloud® environment to ensure always updated antivirus scanning to prevent viruses and spam from filling up the seafarer’s inbox.
