Marta K.

Senior Detection Engineer & Incident Responder

Marta K. is a senior detection engineer and incident responder with over eight years of hands-on experience operating and scaling security operations in high-growth SaaS and fintech environments. She started her career as a SOC analyst, working night shifts triaging alerts and investigating suspicious activity across endpoint, identity, and cloud environments. Over time, she moved into detection engineering, where she focused on building and tuning detection pipelines, reducing false positives, and mapping coverage to frameworks like MITRE ATT&CK. Marta has led incident response efforts for ransomware, credential compromise, and insider threat scenarios, and has helped teams transition from reactive alert handling to structured investigation workflows and proactive detection strategies. Her work has included implementing detection-as-code practices, improving alert fidelity, and designing playbooks that actually get used during real incidents. She writes about the reality of running security operations — from alert fatigue and broken escalation paths to what actually works when building detections and responding to incidents under pressure.
