What I'm looking for

I want to deliver NIST-CSF Security as a Service for SMBs: Zero Trust access, Wazuh SIEM/SOC workflows, hardening & monitoring, plus backup/DR—so teams can prevent and respond to real risks without a full security team.

I’m a cybersecurity specialist focused on small and medium businesses, helping them build reliable, predictable cyber protection without maintaining an internal security team. I work according to the principles of the NIST Cybersecurity Framework, combining practical technical security, security architecture, and constant monitoring in a Security as a Service format.

I specialize in creating comprehensive security infrastructure, including Zero Trust for distributed teams and lightweight SOC capabilities with Wazuh SIEM and response automation via TheHive, Cortex, and n8n. I also deliver server, cloud, and DevSecOps security through hardening, threat detection, vulnerability assessment (like Nmap), risk management, and backup/Disaster Recovery planning to improve ransomware readiness.
