Sailing has always been a cheap and easy way to get from one point to another. Port authorities also make it a point to ensure the safety and security of all people who step off a boat onto the port. As such, certain VIPs actually choose to visit different countries using the sea. And the security systems that the different ports have are enough to secure the VIP and their group.

The most important factor of the dock security system is actually the visual friend-or-foe recognition system. This is done by assessing the different kinds of nautical flags that vessels carry. This assessment is also done with a code reference that will allow access to the incoming vessel. If port authorities find that they have something questionable on board, they might deny entry until a full investigation has been resolved. They also have tight security checks on the docks. This makes sure that the passengers are also secure from each other.

The story is different if the vessel is carrying a VIP. This is because the VIP is always prioritized in terms of security and entry. When port authorities analyze a vessel's nautical flag and confirm through the code reference that there is a VIP on board, they immediately send out an escort ship to guide in the vessel. This show of security can be an active deterrent for anyone who wants to threaten the VIP's life. The time and effort spent in securing VIPs shows that the state values the people who work for it and those who can contribute to it.
