Montelis engineers air-gapped defenses, zero-telemetry infrastructure, and bespoke cybersecurity architecture for enterprises, executives, and family offices across Europe.
We eliminate every technological vulnerability across devices, communications, cloud perimeters, and digital wealth custody.
Offensive vulnerability audits, penetration testing, SIEM telemetry integration, and proactive exploit mitigation.
Air-gapped on-premise clusters, true self-hosted private clouds, VLAN-isolated enterprise Wi-Fi, and liquid-cooled workstations.
Rigorous alignment with European legal directives — GDPR, ISO/IEC 27001, NIS2, and DORA financial sector resilience.
White-glove operational security for C-Suite leaders, crypto custody holders, and family offices demanding absolute confidentiality.
Fixed investments with clear deliverables. Zero hidden costs, zero data logging, complete technical sovereignty.
Heuristic scan of iOS/Android devices to detect hidden stalkerware, rogue profiles, and tracking beacons.
Hardened messaging architecture (Signal, Session, SimpleX) and PGP end-to-end encrypted mail vault.
Dual cryptographic keys (Active + Air-Gapped) eliminating SMS and authenticator app attack vectors.
Complete router hardening with VLAN segmentation separating smart IoT devices from personal laptops.
OSINT reconnaissance and formal legal removal of personal addresses, phones, and records from 85+ databases.
Offline provisioning of hardware wallets (Ledger, Trezor, Coldcard) with steel-plate backup and passphrase architecture.
End-to-end militarized lockdown for your primary laptop (macOS / Linux / Windows 11 Enterprise) with 30-day priority support.
Single-device deep vulnerability analysis and baseline OS hardening.
Fortified wireless perimeter and zero-leak multi-device architecture.
Complete digital anonymity, hardware encryption, and dark web purge.
Perimeter defense for up to 5 family/corporate devices with 24/7 SLA.
Dedicated on-premise servers, air-gapped cold vaults, and assigned virtual CISO.
Security is an architectural discipline. We reject corporate telemetries and third-party dependencies.
Registered and governed within France and the European Union, enforcing full GDPR protections and Swiss data governance standards.
We log zero client communications, traffic, or cryptographic payloads. Everything remains sealed inside your defense perimeter.
No tier-1 helpdesks or outsourced contractors. Every intervention is handled directly by senior security architects.
Every relationship begins with bilateral non-disclosure agreements, identity compartmentalization, and ephemeral channels.
A structured, repeatable, and mathematically verified implementation methodology.
Deep-dive reconnaissance across public records, leaked databases, wireless emissions, and hardware configurations.
Bespoke defense design: air-gapped enclaves, zero-log DNS, hardware keys, and multi-hop WireGuard mesh tunnels.
White-glove implementation across workstations, routers, and vaults without disrupting ongoing business operations.
Continuous anomaly detection, perimeter telemetry stripping, and real-time alerts on anomalous network beacons.
Under 1-hour containment protocol for compromised sessions, attempted extortion, or lost physical endpoints.
Quarterly compliance audits, updated dark web scrubs, and continuous cryptographic rotation as threats evolve.
All initial consultations are protected under strict NDA and processed via zero-knowledge communications.
Direct response from a Senior Security Architect within 24 hours.
