Who is behind PrivCloud ?
PrivCloud is designed, developed and self-hosted by a freelance cybersecurity consultant with 10+ years of experience on critical infrastructures.
Simon Thémiot
Freelance Cybersecurity Consultant & System / Network Architect
Since 2015, I help companies and freelancers secure their Linux, network and cloud infrastructures: security audits, system hardening, WAF deployment, network segmentation, and design of robust self-hosted architectures. That hands-on experience is directly reinvested into PrivCloud: zero-knowledge model, browser-side AES-256-GCM encryption, French hosting with GDPR compliance.
Areas of expertise
- Linux Debian/Ubuntu - administration & hardening
- Proxmox VE - virtualization & segmentation
- Docker, containers, Nginx reverse proxy
- WAF (Naxsi, SafeLine), application filtering
- Secure network architectures (VLAN, DMZ, bastion)
- Web Crypto API, AES-256-GCM, SSKR (Shamir)
- Zabbix monitoring, Wazuh, NtoPNG, alerts, post-incident analysis
- GDPR compliance, audits & DRP/BCP
A decade of evolution
Foundations & self-hosting (Linux, hosting, network services)

PrivCloud - zero-knowledge platform with end-to-end encryption
Why does this matter to you?
PrivCloud is not a service run by an anonymous marketing team. The code is open and auditable on GitHub, architecture choices are documented on the security page, and fixes are published with the project's history (current version: v1.23.7). You know exactly who you are trusting your files with: an identifiable, reachable professional with a verifiable track record.
