Small businesses, SMEs, Associations: secure your web activity.
Small organizations are prime targets for opportunistic attacks (ransomware, data theft), often due to a lack of basic protection.
Experienced DevSecOps Lead,I secure critical infrastructures and sensitive data daily (ISO 27001 Standard). I propose applying this industrial rigor to your scale, with a pragmatic approach.
🕒AVAILABILITY: EVENINGS & WEEKENDS (OOH)Currently employed during the day, I operate exclusively during Out-of-Hours.
Zero business impact: Invisible maintenance for your clients/teams.
Follow-up: Email response < 24h.
🛠️ MY SERVICES
1. Diagnostics & Hardening (Security) I will turn your server (VPS/Dedicated) into a fortress.
- Flash Audit: Vulnerability assessment and clear report.
- Protection: Firewall (UFW/IPTables), Secure SSH (Keys/2FA), Anti-Bruteforce (Fail2ban, CrowdSec).
- Maintenance: Automated security updates.
2. Backups (Life Insurance) Ensure immediate restart after an incident.
- 3-2-1 backup strategy.
- Encrypted and externalized backups (Restic, S3, Scripts).

3. Web & Emails
- Web: Nginx/Apache/Docker security and SSL certificates (Let's Encrypt).
- Emails: Are your emails landing in SPAM? I configure your DNS (SPF, DKIM, DMARC) to restore your reputation.
💡WHY ME?Unlike a traditional system administrator, I am a former Developer. I understand the code (Node.js, PHP, JS) running on your machines. I secure the infrastructure deeply without 'breaking' your application.
Stack: Linux (Debian/Ubuntu), Puppet, Docker, Wireguard, Git.
