What We Do

Complete Linux Security

From initial hardening to ongoing 24/7 protection, we cover every attack vector.

🔐
SSH Hardening
Key-only authentication, custom ports, fail2ban with canonical whitelist, root login disabled, MaxAuthTries tuned. No brute force gets through.
🛡️
Firewall & ipset Blocking
Hash-based ipset firewall with O(1) lookup. Real-time scanner every 15 minutes. Daily sweep catches every attacker. Auto-expires after 7 days.
🌍
Country Blocking
Block entire countries known for attack traffic. GeoIP-based filtering at the firewall level. Whitelist your legitimate traffic sources.
📊
Daily Health Reports
Automated morning reports covering disk, memory, load, services, SSL certs, backup freshness, attack stats, and PM2 process health.
💾
Backup Monitoring
Automated rsync every 4 hours to offsite backup. Freshness monitoring. Auto-repair if backups go stale. Never lose data.
🤖
Bot Protection
Honeypot fields, gibberish detection, timing checks on all registration forms. Block spam bots before they pollute your database.
🔒
SSL & HTTPS
Let's Encrypt auto-renewal, HSTS headers, TLS 1.2/1.3 only, security headers (CSP, X-Frame-Options, CORS), A+ SSL rating.
🔍
Vulnerability Scanning
Regular scans for exposed .env files, .git directories, default admin pages, outdated software. Fix before attackers find them.
⚡
Incident Response
If something gets through, we respond immediately. Forensic analysis, patch deployment, credential rotation, and post-incident report.
