Protective DNS for marina offices, fuel docks and berth-holder WiFi
A marina runs a booking office, fuel-dock card terminals, CCTV and gate systems, and WiFi for berth holders and visiting crews, often with a small team. Shield answers each DNS lookup and blocks phishing, malware and command-and-control callbacks before a connection starts. Payment and office networks get threat-first rules, berth holders get family-safe WiFi without ads, and nothing needs installing on their devices.

What is at stake
A small team with a lot of networks
Fuel-dock card payments
Payment terminals on the fuel dock and in the chandlery take cards all season. They need to sit apart from berth-holder WiFi, on threat-first rules.Phishing at the marina office
Berthing requests, invoices and changed bank details arrive by email all year. One convincing lure can hand over the booking system.Visiting crews, unknown devices
Each visiting yacht brings phones and laptops you have never seen, on the same WiFi as long-term berth holders.

FAQ
Questions we hear from teams like yours
Do we need hardware out on the pontoons?
No. Point your router, firewall or DHCP at Shield and the marina network is covered, from the office to the furthest pontoon. There is no appliance to fit and nothing to install on berth holders' devices.
Can berth holders and visiting crews have different rules?
Yes. Each SSID or VLAN carries its own policy, so berth holders, visitors, staff and payment systems each get the rules that suit them. Policies can also change by time of day and day of week.
Will it slow the WiFi on a busy summer weekend?
No. Blocking ads and trackers removes traffic, so pages load up to 500% faster and use up to 44% less data, in Purple's own measurements. That matters most when a full marina shares one link.
How does it help with PCI DSS on the fuel dock?
Shield helps you meet it. Card terminals sit on their own VLAN with threat-first rules, malicious lookups are blocked before they connect, and scheduled PDF reports give you evidence of the control for your assessor.
What if Shield goes down?
It runs on a dual anycast DNS network, so if one node or network fails the next one answers, and it fails closed, so an outage never leaves berth-holder or payment networks unfiltered. It sits behind your firewall as an extra layer, not in place of it.
