Cydome Security: From Alerts to Action – Complete Cyber Security for Ships
November 3, 2025
Cyber incidents at sea don’t arrive as tidy IT tickets. They show up as alarms that won’t clear, black screens on the ECR console, and a schedule that starts slipping. Cydome takes a maritime-first approach: it discovers every connected asset on board, tracks risky changes in real time, and turns IMO, flag, and class requirements into a living checklist for each vessel. That means fewer surprises during PSC or SIRE, tighter control over vendor remote access, and faster containment when something goes wrong, so the ship spends more days earning and fewer days explaining.

Shipowners save by:
- Faster detection and containment: Real-time monitoring, anomaly detection, and an integrated EDR option shorten the window from alert to fix and help protect earnings when a workstation or network is hit.
- Real Discounts: Cydome offers a fixed-percent discount to customers who come via the Ship Universe Savings Alliance (Susa), which can result in substantial savings on the final invoice.
- Controlled vendor remote access: Purpose-built remote access management lets owners start, scope, and stop third-party sessions and keep the rest of the network segmented during maintenance.
- Audit-ready compliance: Automated checks and compliance automation generate the evidence regulators and class ask for, which reduces prep time and surprise findings at inspections.
- Live asset inventory: Continuous mapping of onboard IT, OT, comms, and IoT devices gives a current list of what is connected, so fixes and patches target real equipment.
- Vulnerability scanning and risk management: Fleet-wide views surface the riskiest items first and help plan work and budget by impact.
- Managed monitoring available: A 24×7 SOC service can handle alerting and initial response so fewer tasks fall on ship and office staff.
- Class and ISO assurance: The platform is endorsed by ClassNK, carries RINA cybersecurity class certification, and the company reports ISO 27001 and ISO 27017 certifications.
- Crew phishing readiness: Short, repeatable campaigns build recognition habits that lower credential loss incidents.
- Vendor-agnostic deployment: Works alongside existing network and communications providers for vessels, offshore assets, and shore facilities.
- IACS UR E26 and E27 alignment: Productized support helps align cyber activities and documentation with the new unified requirements for control systems.
- Central control across the fleet: A single dashboard brings protection, risk, and compliance views into one place for ships and shore.

What a cyber incident really costs on a working ship
Most of the bill does not come from the malware itself. It comes from time lost, outside help, and knock-on effects. The calculator below converts your numbers into a yearly view for your fleet.
Downtime drives the total
IR and restore add up
Penalties and rejects hurt
Tow and overtime surprise
Where the time cost comes from
- Waiting on approvals and remote access windows
- Finding the right device and isolating it safely
- Rebuilding accounts and checking data integrity
Where the cash cost comes from
- External incident response and forensics
- Replacement hardware and license resets
- Overtime, port delays, or tow and callouts
Knock-on risks to watch
- Detention or failed inspection after an event
- Cargo or schedule penalties
- Future scope escalation if fixes are deferred
How the math works
Downtime cost = your day value × downtime days.
Cash cost = incident response + penalties + hardware + tow or overtime.
Annual total = expected incidents × (downtime cost + cash cost) across the fleet.
Tip: Use your latest voyage day value and your last two incident reports as a starting point. Then tune the reductions in Step 3 to match your current controls.

ROI vs platform spend

Step 1 — Your fleet
Use TCE, budget day rate, or your internal day value.
Enter the annual license and service cost you expect to pay.
Step 2 — Typical incident types
Tip: Frequency is per ship per year. Costs are per incident. Downtime uses your day value from Step 1.
Step 3 — Effects of protection
Reductions apply to incident frequency, downtime, and cash costs like IR, penalties, and tow. Hardware is assumed unchanged.
Results — Annual totals
| Category | Baseline (fleet) | With protection |
|---|---|---|
| Downtime | $0 | $0 |
| External IR & help | $0 | $0 |
| Penalties / cargo impact | $0 | $0 |
| Hardware / access restore | $0 | $0 |
| Tow / overtime | $0 | $0 |
| Platform cost | $0 | $0 |
| Total | $0 | $0 |
