Keep technical teams and wider business functions updated on current threat landscapes, security capabilities, and system updates. Ensure network infrastructure aligns with maritime security frameworks, UK government policies, and defence‑level operational standards. Produce internal technical documentation, secure configuration guides, FAQs, and incident response process layouts.
• Support & Internal Training: Provide tier‑3 technical security support in high‑level engineering meetings, troubleshooting calls, and customer architecture reviews. Deliver internal security awareness training and technical handovers for network engineers, support staff, and back‑office teams. Coordinate Technical Security Bulletin distribution alongside local management to address emergent CVEs or critical software patches. Carry out regular security audits and product vulnerability comparisons.
