  • Maintain network segmentation, VPN security policies, and IDS/IPS rules to prevent unauthorized access.
  • Conduct periodic firewall rule audits to align with business needs and regulatory requirements.

MSSP & Security Operations Support

  • Act as a liaison between the organization and MSSP, ensuring effective SOC operations and response coordination.
  • Validate MSSP escalations, ensuring proper threat triage and response actions.
  • Evaluate MSSP service level agreements (SLAs) and recommend improvements to security monitoring strategies.

Security Engineering & Continuous Improvement

  • Develop and implement security automation (e.g., SOAR, scripting, integrations) to streamline incident response.
  • Conduct security architecture reviews, identifying and mitigating risks in new and existing technologies.
  • Provide mentorship to junior team members, sharing best practices and incident handling expertise.
  • Other duties as assigned.

Required Qualifications

  • 10+ years of cybersecurity experience, preferably in enterprise environments.
  • Proven expertise in incident response, including threat hunting, forensic analysis, and mitigation strategies.
  • Strong hands-on experience with EDR/EPP solutions, with a track record of fine-tuning detection capabilities.
  • Firewall administration experience with platforms such as Cisco, Fortinet, or Palo Alto.
  • Familiarity with MSSP operations and how to effectively integrate outsourced security monitoring into an enterprise security program.
  • Solid understanding of SIEM, IDS/IPS, and cloud security solutions.
  • Experience with security automation (SOAR, scripting, Python, PowerShell, etc.) is a plus.
  • Must possess a blue-collar work ethic and ambition to succeed and outperform.
