Satellite constellations perform differently depending on route, region, and traffic conditions. Each has distinct strengths and limitations related to coverage, congestion, latency, blockage, and licensing and geopolitical situations.

Sealink’s Multi-LEO approach is designed to maintain high availability of low-latency, high-bandwidth connectivity across changing conditions - helping ensure critical services remain available when they are needed most and your crew stay connected. 

Sealink Multi-LEO provides a highly secure connectivity solution by combining resilient multi-orbit satellite access with Marlink’s integrated cyber security services. Traffic is protected end to end through managed firewalls, secure gateways, continuous monitoring, and threat detection, ensuring that customer networks remain isolated from cyber threats even when switching dynamically between LEO constellations. By embedding cyber security directly into the connectivity service, Marlink delivers a robust, always-on solution that safeguards data, applications, and operations while maintaining high performance and availability for mission-critical maritime and remote communications.

Support crew welfare and business-critical applications with connectivity aligned to operational priorities - delivering the right balance of speed, latency, reliability and service assurance.

One partner. One service model.

Marlink brings design, integration, monitoring, support and lifecycle management together, delivering a consistent, scalable experience across vessels and fleets.
