About Ivan

I help organizations improve security operations through detection engineering, incident response, SIEM/XDR operations, and security automation.

Currently working as a Cybersecurity Engineer at Admirals and Cybertex Security, where I investigate security incidents, manage detection and response workflows, support infrastructure security decisions, and collaborate with technical leads and stakeholders across the organization.

My experience includes:
- SIEM/XDR engineering and operations (Wazuh, Cortex XDR, Elastic Stack)
- Threat detection and incident response
- Identity and access security with Microsoft Entra ID
- Vulnerability management and endpoint hardening aligned with CIS Benchmarks
- Application security reviews and vendor risk assessments
- Security awareness initiatives, including phishing simulation and employee training campaigns
- Security automation using Python, PowerShell, Bash, APIs, n8n, and AI/LLM integrations

I also have a software development background, which helps me approach cybersecurity from an engineering and automation perspective rather than only operationally. I regularly build internal tooling, automate workflows, and work on practical security-focused solutions.

Outside of daily operations, I actively participate in cybersecurity and defence-tech hackathons focused on resilience, AI, infrastructure security, and emerging technologies.
