Cameras only you can see. Even when nobody is home.
The problem
Your yacht has a firewall. Your family's phones don't.
Wealth moves — at twelve knots, at forty-one thousand feet, between three homes. Attackers don't go for the hardened target. They go for the crew phone, the camera at the gate, the invoice nobody double-checks.
Your location, published
A crew story, an open AIS feed, a photo with GPS data. Your whereabouts are rarely hacked — they are posted.
One changed bank detail
Forged invoices for fuel, berths and refits are a well-known attack on captains and family offices. It takes one email to redirect a six-figure payment.
One link, one failure
One satellite link, one router, one password every contractor knows. When it fails, it fails in front of your guests.
Why Leeward
One partner. Every place. A written standard.
Most owners deal with a different provider for every yacht, home and system — and none of them sees the whole picture. Leeward plans, supplies, installs and looks after everything from one source, worldwide, and measures it against twelve written rules.
Topic
Leeward
Typical providers
Hardware
Supplier-neutral selection, supplied and installed by us — every price shown openly.
Often tied to one manufacturer or distributor.
What we look at
Yacht, aircraft, estates and the family's devices — one perimeter.
One vessel, one property or one service.
What we measure against
The Leeward Standard: twelve written rules, checked every year.
A project specification or a service level for the link.
Contracts & data protection
A German company: German contract law, GDPR and BDSG, data hosted in the EU.
Depends on the provider, its subcontractors and their jurisdiction.
Worldwide
Survey before the crossing, monitoring from Hamburg, on site wherever you are.
Usually local — a new provider in every country.
Who you talk to
One partner for every yacht, aircraft and home.
A separate provider for every property and system.
Programmes
Six programmes. One standard.
Every engagement starts with a Survey. Everything else builds on what we find — for one yacht or an entire portfolio.

Format: One-off · fixed fee
The complete picture. In writing.
On board, on site or in the hangar, we map every link, device, account and access. You receive a prioritised report: what is exposed, what it would cost you, and what to fix first.
We test every network, satellite and 5G link, router, camera, door system, laptop, phone and cloud account against the twelve rules of the Leeward Standard — on board, on site or in the hangar. Every finding is rated by risk and cost, so you, your captain, flight department or family office know exactly where to start.
Ideal for
New owners, after a refit, a new captain or family office — or simply when nobody has the full picture.
Typical duration
Depending on scope: days on site, then analysis and a written report
What you get
◆On-site survey of every link, device and account
◆Network and Wi-Fi map for owner, guests and crew
◆Exposure check: what is visible from the internet
◆Risk report rated against the Leeward Standard
◆Prioritised roadmap with cost estimates
◆Debrief with you and your crew or staff
Outcome: A clear, written answer to: how exposed are we — and what do we fix first?
Starlink, 5G, VSAT and fibre combined with automatic failover — so calls and streams survive a change of anchorage, airspace or weather.
We design a multi-link system that combines Starlink (LEO), 5G/LTE with external antennas, VSAT and fibre where available. Traffic is bonded or failed over automatically, guest and crew traffic is prioritised, and the owner's network always comes first — at anchor off Formentera, on passage to Sardinia or arriving at the finca.
Ideal for
Yachts with patchy coverage, remote fincas and villas, owners who work while they travel.
Typical duration
Depending on scope, including hardware supply and installation
What you get
◆Coverage and link analysis for your cruising area or property
◆Multi-link and failover design (LEO, 5G, VSAT, fibre)
◆Separate, prioritised networks for owner, guests and crew
◆Wi-Fi design for decks, interiors and outdoor areas
◆Supplier-neutral hardware, supplied and installed
◆Acceptance test of failover and speeds
Outcome: Calls and streams that survive a change of anchorage, airspace or weather.
Separate networks for owner, guests and crew, hardened devices and the cyber documentation your flag, class and insurer ask for — including IMO cyber risk management and IACS E26/E27 for new builds.
We separate and harden the networks that matter: owner, guests, crew, CCTV and access control — and, strictly isolated, bridge, engine and avionics systems. Remote access moves to zero-trust connections with multi-factor authentication. For yachts we write the cyber section of your safety management system in line with IMO Resolution MSC.428(98) and support new builds with the requirements of IACS UR E26 and E27.
Ideal for
Yachts under flag and class, estates with CCTV and access control, flight departments.
Typical duration
Depending on scope, then an annual review
What you get
◆Network segmentation and firewall rules
◆Zero-trust remote access with multi-factor authentication
◆Hardening of routers, cameras, door systems and laptops
◆Offline backup concept with restore test
◆Cyber section for the ISM safety management system
◆IACS E26/E27 support for new builds
Outcome: A segmented, documented system that stands up to the questions of flag, class and insurer.
Phones, laptops, accounts and homes of principals and family — secured without changing how anyone lives. Including rules for social media and travel.
The most exposed part of any perimeter is personal: the phones, e-mail accounts, cloud storage and social media of principals, family and close staff. We secure devices and accounts without changing how anyone lives, agree rules for live locations and photos, and brief everyone before travel. Changed bank details are confirmed by call-back — the simplest defence against invoice fraud.
Ideal for
Principals and families, family offices, executives with a public profile.
Typical duration
Onboarding depending on household size, then annual
For new builds and refits we write the IT specification, review yard and integrator proposals and sign off delivery — so you pay for what was promised.
Most IT problems on a yacht are built in at the yard. We write the IT and connectivity specification for your new build or refit, review the proposals of yard and integrator line by line, attend key milestones and run the acceptance tests before you sign — so the Leeward Standard is built in from the start, not patched in afterwards.
Ideal for
New builds, major refits, owner's representatives and project managers.
Typical duration
Throughout the project — from specification to sign-off
What you get
◆IT and connectivity specification
◆Review of yard and integrator proposals
◆Review of rack, cabling and antenna placement
◆Milestone inspections on site
◆Acceptance testing before sign-off
◆Handover documentation for captain and ETO
Outcome: You pay for what was promised — and get a system your crew can run.
Monitoring, updates and an agreed response time, in writing — delivered with vetted partners in the regions you use.
Systems drift: firmware ages, crews change, contractors keep old access. Leeward Watch monitors links, devices and backups continuously, applies updates in agreed windows and responds to incidents within an agreed time — delivered with vetted partners in the regions you use. Once a year we review everything against the Leeward Standard.
Ideal for
Every yacht, aircraft or property after a Survey or project.
Typical duration
Monthly, per yacht, aircraft or property
What you get
◆Monitoring of links, devices and backups
◆Patch and firmware management
◆Access reviews when crew or staff change
◆Incident response with agreed response times
◆Quarterly report in plain language
◆Annual review against the Leeward Standard
Outcome: Someone keeps watch — and you hear about problems before your guests do.
Equipment changes. The standard stays: every yacht, aircraft and home is measured against the same twelve rules.
§ 01Owner, guest and crew networks are separated. Always.
§ 02Bridge, engine and avionics systems stay isolated from guest IT.
§ 03Two independent internet paths with automatic failover.
§ 04Cameras and door systems are never directly exposed to the internet.
§ 05No device keeps its factory password.
§ 06Every important login — e-mail, cloud, banking, remote access — uses passkeys or multi-factor authentication.
§ 07Access is personal and logged — and ends the day the job ends.
§ 08Every device is inventoried, encrypted and kept up to date.
§ 09Changed bank details are confirmed by call-back. Every time.
§ 10Live locations stay off by default — for family and crew.
§ 11Backups exist offline and are restored in a test every year.
§ 12A written incident plan — and everyone trained on it before the season.

About
An architect who flies and sails. One partner for everything.
Leeward was founded by a cloud and security architect who designs infrastructure for large enterprises — and who holds a pilot's licence and boat licences. That combination is rare: we understand a flight department's checklist and a captain's watch system as well as a firewall policy. And we speak to your crew in their language. Headquartered in Hamburg, we work on site wherever our clients are.
Principles
What you can hold us to
Supplier-neutral
Tied to no manufacturer. We recommend what fits — and show every hardware price openly.
Invisible
Racks behind joinery, cables where the designer wants them, nothing blinking in the salon.
Discreet
Client names never appear in our marketing. References are shared in person, with consent.
Accountable
One contact who answers for the whole system — across yachts, aircraft and homes.
Founding clients · 2027 season
5 places for founding clients.
We are taking on a small number of yachts, aircraft and estates for the 2027 season. Founding clients work directly with the founder and fix their first-year terms.
Because nobody can secure what nobody has mapped. The Survey gives you a written picture of every link, device and account — and a prioritised plan. It is a fixed fee, and you keep the report whether or not we work together afterwards.
Do you supply the hardware as well?+
Yes — everything from one source. We recommend supplier-neutral hardware for your yacht, aircraft or home, supply and install it with vetted partners and look after it afterwards. Every price is itemised. If you prefer to buy yourself, we specify and accept delivery.
Can you replace our current IT providers?+
Yes, if you want: most clients move from several providers per property to one. Where an ETO, flight department or estate staff are in place, we work alongside them and take over the coordination.
Do you install equipment on aircraft?+
Not ourselves. Anything fitted to an aircraft requires an approved maintenance organisation and certification. We specify, choose the partner and supervise; an EASA Part-145 approved shop carries out the installation.
Where do you work?+
We are headquartered in Hamburg, Germany. We work on site across Europe and the Mediterranean, and worldwide by arrangement — wherever your yacht, aircraft or home is. Monitoring and support are remote.
How do you handle confidentiality?+
NDA before the first visit, client names never published, data stored in the EU, and access only where needed — and logged.
What does it cost?+
Every engagement is priced to its scope. The Survey is a fixed fee after the briefing, projects are quoted per scope with hardware itemised, and Leeward Watch is a monthly fee per yacht, aircraft or property. You get the price in writing before we start.
