Chalet IT & Cybersecurity in Courchevel 1850

Courchevel 1850 is, by most measures, the most expensive ski real estate in France. Ultra-prime chalets around Le Jardin Alpin and the Bellecôte piste trade at over €30,000 per square metre — with the finest addresses reaching €31,670 and beyond — placing them alongside the priciest Swiss resorts and ahead of nearly everything else in the Alps. The buyers' register reads like a private bank's: French and British industrial families, Gulf royalty, and a long Russian chapter that shaped the resort's appetite for discretion. These are not holiday homes. They are nine-figure assets with staff quarters, spa levels, private cinemas and, increasingly, a full working office for a principal who runs a family office from the mountain between December and March.

And yet the technology inside most of these chalets would embarrass a mid-market hotel. The 2025–26 lifts ran from 5 December to 19 April — roughly 136 days. For the remaining seven months the chalet sits dark at altitude: automation live, cameras half-watched, a consumer router still broadcasting, a management agency holding the alarm codes. When the family returns by way of the altiport — the legendary 537-metre sloped runway perched at 2,008 metres — everything must simply work, and nothing must have been touched. That gap between asset value and technical custody is precisely what a private IT office exists to close.

Le Jardin Alpin: the densest square kilometre of risk in the Alps

Le Jardin Alpin concentrates palace hotels, three-Michelin-star dining and a handful of the most valuable chalets in Europe inside a wooded enclave the size of a city block. That density cuts both ways. Every device in such a chalet — lighting controllers, ski-room boot dryers, pool plant, AV racks, staff tablets — shares radio space with hundreds of guest devices, contractor phones and hotel networks metres away. A poorly segmented chalet network is visible, enumerable and, to a motivated adversary who knows exactly who winters where, attractive. We design chalet networks the way we design estate networks for principal residences: hard segmentation between family, staff, guest, automation and CCTV planes; certificate-based access; and no device on the property that we cannot name, locate and revoke.

The rental paradox: strangers on your network

Many 1850 chalets — even at the very top — rent for €200,000 to €400,000 per week in peak season. Each booking imports a new household: principals, security details, nannies, chefs, and forty unknown devices that expect flawless wifi from the ski room to the master suite. The owner's dilemma is real. Refuse connectivity and the chalet loses its rating; offer it carelessly and this season's tenant can reach last season's camera archive, the owner's NAS, or the building management system that controls heating in a structure where a frozen pipe is a seven-figure event. The answer is an architecture, not a password: ephemeral guest realms that are created for a booking and cryptographically destroyed at checkout, with the owner's plane of the network physically and logically unreachable — the same discipline we document in our work on private villa and rental wifi design.

Seven dark months at 1,850 metres

Off-season is when chalets are actually lost — to water, to intrusion, to silent compromise. Mountain connectivity is the constraint: fibre serves the resort core but fails under storm and works-season cuts, so we layer it with bonded 4G/5G and LEO satellite, giving the chalet three independent paths to the outside world. On top of that we run year-round telemetry — environmental sensors, camera health, automation heartbeats, network anomaly detection — reviewed by humans, not just dashboards. French law is unforgiving about cameras that overlook the voie publique or neighbouring properties, and in an enclave like Le Jardin Alpin the neighbours are palace hotels with their own counsel; we position and mask surveillance to protect the asset without creating legal exposure.

A Courchevel chalet is the only nine-figure asset most families own that is operated, in practice, by whoever last had the wifi password.

Staff churn & the seasonal workforce

The resort runs on seasonal labour: chalet hosts, drivers, ski instructors, agency housekeepers who arrive in November and scatter in April. Every one of them touches the property's technology — door codes, camera apps, sonos systems, the printer in the office. Without managed identity, access accretes and never expires; three seasons later, a former employee's phone still opens the boot room. We bring family-office discipline to this churn: individual credentials, automatic expiry tied to contract dates, and a quarterly access audit the principal can read on one page. The same continuity layer carries the principal's working life — trading, signatures, board calls — through the winter months, so that the chalet office is as defensible as the one in Geneva or London. For arrivals and departures through the altiport, our private aviation cybersecurity practice extends that perimeter to the aircraft itself.

Engineered remotely. Present when it matters.

Obsidian Helm operates as a fully remote private technology office: architecture, procurement guidance, hardening, monitoring and incident response delivered worldwide under NDA, with trusted local hands engaged only under our supervision. We already apply this model across the Alps — see our companion brief on St. Moritz chalet security — and across the rest of a principal's footprint, from yachts and jets to primary estates. The mountain should be where the family is least reachable by the world — and most certain that everything behind the larch facade is watched, segmented and quietly under control.
