Serving in the role of Security Analyst, you will join Vectra's MXDR team and use your knowledge of cyber threats, attacker behavior, and investigation techniques to analyze and interpret real-world attacks affecting our customers. You will investigate suspicious activity, correlate indicators across multiple data sources, identify attacker tactics and lateral movement, and communicate findings in a clear and actionable manner to customers. 

As part of the Vectra MXDR team, you will monitor, triage, investigate, and respond to security events across customer environments using the Vectra platform, integrated EDR technologies, and supporting security tools. This is a customer-facing operational security role requiring strong analytical thinking, effective communication, and a solid understanding of modern attack techniques and enterprise environments. 

You will help customers distinguish benign from malicious activity, prioritize threats based on risk and impact, and provide guidance during active investigations and incident response situations. Leveraging Vectra’s AI-driven detections and telemetry, you will contribute to protecting customer environments against advanced threats while continuously improving operational detection and response capabilities. 

This is a highly technical role requiring strong knowledge of networking, operating systems, and security operations principles. Successful candidates will be comfortable analyzing alerts, validating threats, investigating attacker activity, and working across complex customer environments. 

When not actively engaged in customer investigations, analysts are expected to contribute to operational improvement initiatives, detection tuning, threat research, playbook development, and knowledge sharing activities that strengthen both the team and customer outcomes.
