Protect your marine based assets with 24/7 automated monitoring and alerting directly to vessels navigation systems

Ultimate Protection

Guardian:protect provides unparalleled protection for marine based assets.

Operating 24/7, it proactively intervenes to prevent vessels from causing damage.

Most damage to marine infrastructure is the result of human error. Guardian:protect prevents errors by sending an automated message directly to vessels that present a risk to your asset before an incident occurs.


By making the vessel navigator aware of your asset via an on-screen message on their navigation system, Guardian:protect reduces the likelihood of an incident by 88.4%. 

We achieve this by constantly monitoring all AIS vessel traffic for breaches of customizable smart rules and automatically alert both you and the vessel if a breach is detected.

Without Guardian:protect, your asset is an accident waiting to happen.

Widespread use cases

Guardian:protect is unique in its ability to differentiate between vessels that are operating normally (and therefore not a risk) and those that are potentially about to damage your asset. It gives both passive and active protection against higher risk activity near:

Oil & Gas

From offshore installations to inshore pipes, we prevent collisions and anchor damage

Submarine Cables

We prevent anchor damage to electricity and telecommunication cables

Marine Zones

Protected marine environments, launch ranges and incident zones.

Ports and Coastline

Small to mediume ports protect vessels from groundings and collisions


We create electronic protection zones and virtual bouys

When a rule is triggered we send a message to the vessel

The message is displayed on the vessel’s navigation system

Alerts are also sent via Guardian Cloud app, email or text to your team

Learn how Guardian works

Comprehensive Functionality

Rich features enable customization and control of how assets are marked, how alert rules are configured and what proactive messages are sent to vessels.

    • Create multiple protection zones around your assets by defining buffer areas or drawing specific coordinates.
    • Route positions and asset location coordinates can be uploaded in a variety of coordinate formats.
    • Set up vessel groups and assign individual vessels to groups: e.g. trusted vessels such as work boats and tenders.
    • Configure alerts based on smart rules including vessel type and vessel groups, speed over ground, change in speed (sudden slowing), change in direction (veering off course).
    • Changes to rules can be tested using historical data, rather than waiting months for the next event to test their effectiveness.
    • Interrogate individual vessel details, track the vessel, and measure the distance from the asset.
    • Integrate radar information to include non AIS vessels, icebergs, oil spills and other radar enabled targets to determine risk.
    • Define the type of alarm based upon severity: raise audible and visible alarms within the control room or network operations center and send automatic SMS or email to a defined group of users.


    Guardian Cloud is the brains.  It processes AIS data from Guardian Shore Stations, applies smart rules and manages alerts.
