• Participate in Proof of Concepts (POC), product evaluations, feature testing, and security tool assessments.
• Develop onboarding documentation, operational runbooks, implementation procedures, and knowledge transfer materials.
• Collaborate with cybersecurity architecture and governance teams to align EDR deployment with security standards and compliance requirements.
• Conduct tuning and optimization of EDR policies, detection rules, exclusions, and alert thresholds to reduce false positives.
• Manage endpoint security posture by monitoring agent health, policy compliance, coverage gaps, and platform performance.
• Perform Day 2 operational activities including upgrades, patching, troubleshooting, policy management, and platform maintenance.
• Support Infra related vulnerability, remediation coordination, and hardening initiatives.
• Support audit, compliance, and regulatory activities related to endpoint security platform and operations.
• Coordinate with vendors and MSSP partners for issue resolution, feature enhancements, and product roadmap discussions related to the platform.
• Participate in 24x7 on-call support and incident related to the platform and infra whenever required and need to be on standby.
• Lead and work with cross-functional stakeholders and processes to meet the business requirements.
