Security First

Elimination of security vulnerabilities in outdated components, implementation of modern security practices without changing fundamental system architecture.

Documentation and Knowledge

Creation of comprehensive documentation for future support, knowledge transfer about system, preparation of procedures for company's regular IT specialists.
