Linux Management & Migrations

Professional Linux administration, hardening, and migrations with a security-first approach.

Overview

Linux is the foundation of modern infrastructure. We provide professional Linux management, migrations, and hardening. Always with a security-first approach. Whether it’s daily operations, migrating legacy systems, or setting up a completely new environment: we ensure your Linux servers are reliable, secure, and up-to-date.

Our Approach

  • Security First: Security is not an afterthought but the starting point. Every configuration, every migration, and every management action is executed with security as the first priority
  • Linux Management: Daily operations, patching, monitoring, and troubleshooting of your Linux environment. Proactive rather than reactive
  • Migrations: Migration from legacy systems (Unix, older Linux distributions) to modern, supported platforms with minimal downtime
  • Hardening: CIS benchmarks, kernel hardening, SELinux/AppArmor configuration, and continuous compliance monitoring
  • Automation: Configuration management via Ansible or Salt Stack so your environment is consistent, reproducible, and auditable

Security First Principles

We work from proven security-first principles:

  • Least Privilege: Minimal permissions, maximum control
  • Defense in Depth: Multiple security layers, never depending on a single measure
  • CIS Baselines: Configuration according to CIS benchmarks for demonstrable compliance
  • Patch Management: Structured and timely patching with rollback capabilities
  • Audit & Logging: Full traceability of changes and access
  • Zero Trust: Always verify, never implicitly trust
