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) |
| 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) |
| 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:
- Buy a Google Pixel (6, 7, 8, or Pro versions)
- Go to grapheneos.org
- Use the web installer (very simple)
- 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:
- The basics — Unique passwords + 2FA = essential protection
- The tools — ProtonMail, Brave, trusted VPN
- Mobile — GrapheneOS for real privacy
- Address — Domiciliation to blur the trails
- 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.
