In 2024, over 100 million records of French citizens were exposed during cyberattacks. CAF, France Travail, Viamedis, SFR, Free, police files... No sector was spared.

The government cannot protect you. Companies fail to secure your data. The only solution: take back control yourself.

This complete guide gives you the tools and methods to protect your digital life, from basics to advanced measures.


Assess Your Exposure

First step: know what has already leaked about you.

1. Check If Your Data Has Leaked

HaveIBeenPwned.com

The reference site to know if your email has been compromised:

  • Free
  • Covers billions of breached accounts
  • Alerts on new leaks

What to do if you're listed:

  • Change passwords for affected accounts
  • Enable 2FA everywhere
  • Monitor accounts for suspicious activity

2. Request Your Data from Organizations

Under GDPR, you can request:

Right Description How to Exercise
Access Know what data is held Email to DPO
Rectification Correct errors Written request
Erasure Delete your data Justified request
Portability Retrieve your data In usable format

3. Complete Audit with GetSpecter

For an overview of your digital exposure, GetSpecter.app offers an automated audit:

  • Analysis of your digital footprint
  • Detection of leaks concerning you
  • Personalized recommendations
  • Continuous monitoring

Secure Your Accounts: The Basics

Strong unique passwords and 2FA everywhere: the foundation of your digital security.

1. Unique and Strong Passwords

The problem:

  • 65% of people reuse their passwords
  • One compromised password = all accounts at risk
  • Hackers automatically test on other sites

The solution: A password manager

Tool Advantages Price
Bitwarden Open source, audited, cloud or self-host Free/€10/year
KeePass Local, open source, very secure Free
1Password Polished interface, family plan €35/year

Avoid: LastPass (multiple data breaches)

2. Two-Factor Authentication (2FA)

2FA adds a security layer even if your password leaks.

Types of 2FA (least to most secure):

Type Security Recommendation
SMS Low Avoid (SIM swapping risk)
Email Medium Acceptable
App (TOTP) Strong Recommended
Physical key Very strong Ideal

Recommended TOTP apps:

  • Aegis (Android, open source)
  • Raivo OTP (iOS)
  • Authy (multi-platform)

Physical keys:

  • YubiKey — Industry standard
  • Thetis — Cheaper alternative

3. Where to Enable 2FA First

Account Priority Impact if Hacked
Primary email CRITICAL Access to all accounts
Bank CRITICAL Money theft
Ameli/CAF/Taxes High Administrative identity theft
Social media Medium Reputation, phishing

VPNs: Beware of False Friends

ExpressVPN, CyberGhost acquired by Kape: avoid these privacy false friends.

The Problem with Commercial VPNs

The majority of popular VPNs have been acquired by Kape Technologies, an Israeli company:

VPNs owned by Kape Technologies:

  • ExpressVPN
  • CyberGhost
  • Private Internet Access (PIA)
  • ZenMate

Why this is problematic:

  • Centralization of millions of users' data
  • Troubled company history (former malware distributor)
  • Questionable jurisdiction and transparency
  • Business model: is your data really protected?

Truly Recommended VPNs

ProtonVPN (Switzerland)

Criterion Rating
Jurisdiction Switzerland (strong protection)
Open source Publicly audited
No-log Verified by audits
Free version Available
Ecosystem ProtonMail, Drive, Calendar

Recommended for most users.

Mullvad (Sweden)

Criterion Rating
Anonymity No account, just a number
Payment Cash, crypto accepted
No-log Verified
Price €5/month flat

Recommended for maximum anonymity.

The Future: Decentralized VPNs

RunOnFlux (upcoming)

A new generation of VPNs based on the decentralized Flux infrastructure:

  • No central point of control
  • Censorship resistant
  • Globally distributed nodes
  • Watch for 2025-2026

Protect Your Email

Google reads your emails to train its AI: switch to ProtonMail.

The Gmail/Outlook Problem

What Google does with your emails:

  • Automatic analysis of content for advertising
  • AI training with your personal conversations
  • Profiling of your habits, relationships, purchases
  • Potential access by authorities (USA CLOUD Act)

The US CLOUD Act: US authorities can request access to data stored by American companies, even if servers are in Europe.

Secure Alternatives

ProtonMail (Recommended)

Criterion Rating
Encryption End-to-end
Jurisdiction Switzerland
Open source Yes
Free tier Available
Ecosystem VPN, Drive, Calendar

The obvious choice to replace Gmail.

Tutanota (Germany)

  • Open source
  • Full encryption
  • Affordable pricing
  • Solid alternative

Email Aliases

SimpleLogin (acquired by Proton) lets you create aliases:

  • A different alias per site
  • If a site leaks, only the alias is compromised
  • Redirection to your real inbox
  • Easy spammer blocking

Browsers: Flee Chrome

Chrome is a Google surveillance tool: Brave gives you back control.

Why to Avoid Chrome

Chrome is a surveillance tool disguised as a browser:

  • Ubiquitous Google tracking
  • History synced by default
  • Ad blocker removal (Manifest V3)
  • Facilitated fingerprinting

Brave: The Recommended Browser

Feature Brave
Ad blocker Built-in
Anti-fingerprinting Active
Chrome compatible Extensions work
Tor integration Private window
Open source Yes

Alternatives

Browser Use Note
Firefox General use Good when hardened
LibreWolf Hardened Firefox More private out of box
Tor Browser Maximum anonymity Slow but very private

Mobile OS: GrapheneOS

Android without Google on Pixel: take back control of your smartphone.

The Android/iOS Problem

Android (Google):

  • Constant location tracking
  • Non-removable pre-installed apps
  • Data synced to Google
  • Personalized advertising

iOS (Apple):

  • Closed ecosystem
  • Data centralized at Apple
  • Less user control
  • Privacy illusion

GrapheneOS: The Sovereign Alternative

GrapheneOS is Android without Google, focused on security and privacy.

Aspect GrapheneOS
Base Android (AOSP)
Google Removed by default
Phones Google Pixel only
Open source Audited
Google Sandbox Optional if needed

Security features:

  • Hardened Linux kernel
  • Granular permissions (per-app network access)
  • Disableable sensors (mic, camera, accelerometer)
  • Isolated user profiles
  • MAC/IP randomization

How to Install GrapheneOS

Prerequisites:

  1. Buy a Google Pixel (6, 7, 8, or Pro versions)
  2. Go to grapheneos.org
  3. Use the web installer (very simple)
  4. Follow instructions (15-30 min)

Why Pixel?

  • Best security hardware on the market
  • Long-term update support
  • Guaranteed compatibility

Domiciliation: Blur the Trails

Protect your real address: 43 million addresses leaked in 2024.

Why Use Domiciliation?

With massive data leaks, your home address is probably exposed:

  • France Travail: 43 million addresses
  • CAF, health insurers, telecom operators...
  • Cross-referencing databases = locating you

Benefits of domiciliation:

  • Protection against harassment
  • Separation of personal/professional life
  • Continuity when moving
  • Less targeted junk mail

Personal Domiciliation

Service Type Monthly Price
La Poste PO Box Basic ~€15
Domiciliation services With mail scanning €20-50
Relay points Parcels Variable

Limitations:

  • Some administrations refuse PO boxes
  • Banks may be reluctant
  • Tax declaration = real address required

FAQ

Why avoid VPNs like ExpressVPN?

ExpressVPN, CyberGhost, PIA, and ZenMate all belong to Kape Technologies, an Israeli company with a troubled past. This centralization is problematic: a single entity controls millions of users' data. Prefer ProtonVPN (Switzerland) or Mullvad (Sweden).

Does Google really read my emails?

Yes. Google automatically analyzes your email content for targeted advertising and to train its AI models. Your personal conversations directly feed Google's AI. Switch to ProtonMail for end-to-end encryption.

What is GrapheneOS?

GrapheneOS is a mobile operating system based on Android but without Google. It offers security and privacy levels far superior to standard Android or iOS. It works exclusively on Google Pixel phones (paradoxically the most secure at the hardware level).

Is domiciliation legal?

Yes, domiciliation is perfectly legal in France, for both individuals and businesses. However, some administrations may refuse PO boxes for specific procedures. Check on a case-by-case basis.

Isn't all this too paranoid?

No. In 2024, over 100 million French records leaked. Statistically, your data is already compromised. The question isn't "if" but "when" it will be exploited. Taking measures now will spare you future problems.


Conclusion: Take Back Control

The massive data leaks of 2024 demonstrated a reality: nobody will protect your data for you.

The government has failed. Companies fail. The only solution: individual digital sovereignty.

Key takeaways:

  1. The basics — Unique passwords + 2FA = essential protection
  2. The tools — ProtonMail, Brave, trusted VPN
  3. Mobile — GrapheneOS for real privacy
  4. Address — Domiciliation to blur the trails
  5. Centralization — GetSpecter to manage it all simply

This digital sovereignty aligns with the financial sovereignty we advocate on this blog. In a world where institutions fail to protect us — data and money alike — taking back control becomes an act of freedom.

Start today. One tool at a time. Your future self will thank you.
