Private Cybersecurity for Courchevel Principals

No resort address in the world sits closer to the top of the mountain than Courchevel 1850. Its famously short, steep altiport delivers a private jet passenger onto the slopes within minutes, and the village built around that access now holds roughly 2,100 ultra-high-net-worth individuals with real ties to the resort, five of them billionaires — a small, dense concentration by global standards, but among the wealthiest per square kilometre in the French Alps. Courchevel 1850 itself holds the ski-in, ski-out mansions closest to the piste; Le Jardin Alpin, the quieter enclave just above the centre, holds larger private chalets set back from the crowds; Bellecôte anchors the newer compounds toward the edge of the domain, still inside the Trois Vallées — the largest linked ski area on earth.

The season is short and intense — roughly December through April — and the households that occupy these chalets scale up dramatically for it: ski instructors, chauffeurs, chefs and chalet staff are hired for the winter and released in spring, often by a rotating cast of local agencies rather than the family directly. That model is efficient for hospitality and porous for security, since access credentials issued through a third-party agency are the hardest for a family office to track.

Wire fraud in a short, intense season

Globally, 43 percent of family offices were hit by a cyberattack within a recent 24-month window, and phishing featured in 93 percent of incidents. A five-month season compressed into a handful of frantic weeks around Christmas and February half-term is exactly when a family office is least likely to scrutinize an unusual invoice or a wire instruction that appears to come from the chalet manager. Deepfake impersonation of the principal exploiting that seasonal rush is now within reach of ordinary criminal groups, and dark-web dossiers on high-profile Courchevel families — arrival dates, staff rosters, chalet addresses — are compiled specifically to time an attack for the busiest week of the season.

Crypto custody on the mountain

A meaningful number of Courchevel's winter residents built their fortunes in finance, technology or private equity, and carry a proportional share of it in digital assets, often managed remotely from the chalet during the season. The custody risk travels with the phone and the laptop, not the altitude: SIM-swap attacks and clipboard malware do not care whether the signing device is in a Geneva office or a chalet at 1850 metres. Our crypto custody protection practice hardens the key ceremony, the signing devices and the household staff who might unknowingly have access to them.

The chalet as attack surface

A 1850 or Le Jardin Alpin mansion is a small hospitality operation for five months a year: integrated heating, lighting, gates and AV systems installed by a local integrator and rarely re-audited between seasons; a large rotating staff, frequently supplied through third-party agencies, carrying personal devices on the household network; smart-home credentials issued to a chalet management company that outlives any single winter. We treat the estate network as critical infrastructure, apply the same discipline specifically to the chalet's technology stack, and extend it to the connectivity aboard the aircraft that lands the family at the altiport each December.

Courchevel built the shortest distance in the world between a private jet and a ski run. Attackers have built something almost as efficient — the shortest distance between a busy holiday week and a wire that never should have gone out.

A private office, not a vendor

Obsidian Helm is operated by IT Cares Canada, a firm serving private clients since 2014, and runs as a single discreet office for everything technology touches: identity and account hardening, wire-fraud controls with out-of-band verification, estate and travel networks, seasonal-staff device governance, and continuous AI-driven monitoring built for family offices. The practice is fully remote and worldwide by design — no local office to be seen entering, no technician's van outside the chalet, no name in a vendor register. Every engagement sits under NDA from the first call. The full scope lives across our cybersecurity and concierge IT practices.

How an engagement begins

Every relationship opens with a Private Strategy Session: a structured, confidential assessment of the family's exposure across accounts, devices, the chalet, seasonal staff, digital assets and the dark web, delivered as a prioritized protection plan on the family's schedule, wherever they are between seasons. Courchevel compressed access to the mountain into a few perfect minutes. The families who protect what they have built compress their digital risk down just as deliberately — before the season opens, not during it.
