YOUR DEVICE, SET UP FOR YOUR PRIVACY
Professional installation, migration and security hardening for Linux and Windows, for anyone who wants a computer that is clean, protected and fully under their own control.
WHO YOU WILL MEET
An independent specialist and lifelong machine enthusiast. I have studied operating systems down to kernel level and keep training myself in cybersecurity. Contact is through tutti.ch messages only; before you commit, we can chat here or meet in person in Martigny.
One person, one device at a time: no outsourcing, no hidden extras. Name and address appear on your written price confirmation and invoice. No security is absolute: the aim is a smaller attack surface and a setup you can verify.
SECURE BOOT 2026 CHECK
Microsoft's 2011 Secure Boot certificates expired during 2026. I check that your device trusts the 2023 replacements, so boot updates keep working on Linux and Windows.
SYSTEMS
Linux: Debian family (Debian, Ubuntu), Fedora, Rocky Linux, Arch family, Slackware family, Gentoo, NixOS.
Windows 11 Home or Pro (Pro recommended). Windows 10 only with active ESU enrolment (personal ESU currently runs to 12 October 2027). Valid licence required. Dual boot on request.
PRICES (CHF)
Base package: CHF 1'000
Includes: installation or migration, verified media, trusted update sources, UEFI/Secure Boot checks, firewall and open-port review, SSH and Samba/SMB hardening, removal of unneeded packages and services, privilege review (sudo, polkit), browser privacy, screen lock. Windows: Defender, Firewall, UAC, updates, Secure Boot/TPM, memory integrity where supported.
Modules (Linux only, where supported), each CHF 750:
1. Kernel and memory: sysctl settings, memory protections, /proc visibility, Linux capabilities
2. Access control: SELinux or AppArmor, sVirt, systemd sandboxing
3. Isolation: seccomp, containers, QEMU/KVM, libvirt, namespaces, cgroups
Complete package (base + all modules): CHF 2'200 instead of CHF 3'250.
LUKS2 disk encryption (optional): +CHF 300 and +1 day.
The final price is confirmed in writing before work begins.
INCLUDED
- Testing of boot, updates, network, standby and agreed applications
- Documented changes with usage instructions
- Temporary maintenance access removed
- You set your own login password
- YubiKey 5C NFC in sealed packaging (you set the PIN and enrol your accounts; guide included); your own key is fine too
- Free correction of configuration issues within 14 days of handover, in addition to your statutory rights
LUKS2 (OPTIONAL)
After a preparation day covering boot, storage and recovery, I hand over the device unencrypted and you complete the setup yourself with my step-by-step instructions. The key is generated locally under your control; I never receive or retain the key or your passphrase. Free correction covers my preparation only.
CONFIDENTIALITY
An NDA can be signed on paper: in person at handover, or by post for remote customers. Personal data is processed only for the agreed work and on your instructions, in line with the Swiss Federal Act on Data Protection (FADP, Art. 9). I do not pass your data to third parties.
HANDOVER
In person (preferred): drop-off and collection in Martigny; you are welcome to attend over coffee. Another Valais meeting point on request.
Remote customers: insured, tamper-evident shipping; I cover the return shipping.
The work is done in a locked workspace to which nobody else has access, within 48 hours of receiving the device and confirming the scope (72 hours with LUKS2). You receive a written record of the device condition and the work done.
BEFORE BOOKING
Send me your device model, preferred operating system and main applications so that I can confirm scope and price. Please back up your data first: a fresh installation erases the selected partitions, a full-disk installation the whole disk. Forensic investigation and post-compromise cleanup are outside my scope.
Disponible en français sur demande.
