Sigitas Slavinskas

I’m a Cybersecurity Analyst with hands-on experience in MSSP SOC operations, vulnerability management, alert triage, endpoint security, cloud security, and incident investigation. I work across SIEM log review and telemetry correlation (Microsoft Sentinel), Microsoft Defender threat hunting and vulnerability investigation, and EDR/XDR/NDR tooling to validate suspicious activity and determine next steps.

I’m also deeply focused on turning findings into action—classifying vulnerabilities by severity and exploitability, creating Jira tickets with clear evidence and deadlines, and coordinating remediation with system owners. From endpoint onboarding with Intune and Defender agents to session revocation, isolation, and indicator blocking, I ensure SLA compliance and maintain audit-ready evidence while supporting risk-acceptance workflows when remediation isn’t immediately feasible.
