Case Study: GTMaritime achieves superior email protection for 4,500+ vessels with Lastline

GTMaritime GTMailPlus Protecting Email from Advanced Threats at Sea and Across the Globe

GTMaritime, a satellite-enabled communications provider serving 4,500+ vessels and 1,000+ customers, faced growing email-borne threats at sea—ransomware, phishing and malicious attachments—that can cripple ship operations and isolate crew. They needed advanced malware detection tailored to constrained satellite links and remote maritime environments to protect both onboard and shore-based systems.

GTMaritime built GTMailPlus around Lastline’s inline MTA sensor and deep content inspection to isolate, analyze and block malicious attachments and URLs before delivery, while providing evidence-based reporting for incident response. The integration was seamless with virtually no false positives, became a compulsory element of the service, and delivered accurate threat eradication plus a cloud dashboard for remote management as it is rolled out across the customer base.
