• Be a trusted responder: Act as a key contributor during network security incidents, ensuring swift response, root‑cause analysis, and continuous improvement of access control defenses.
• Optimize and innovate: Proactively monitor, analyze, and fine‑tune NAC systems to improve performance, resilience, and user experience.
• Collaborate and influence: Partner closely with infrastructure, security, and architecture teams to integrate NAC with SIEM, endpoint, and other security platforms, ensuring a cohesive security strategy.
• Document and standardize: Create and maintain clear, high‑quality documentation of NAC configurations, policies, and operating procedures to support knowledge sharing and scalability.

What We’re Looking For

• Strong NAC expertise: Deep hands‑on experience with Aruba ClearPass Policy Manager (CPPM) for NAC, AAA, and Zero Trust enablement.
• Solid security foundation: A strong understanding of network security principles, including firewalls, IDS/IPS, VPNs, and security auditing.
• Zero Trust mindset: Practical knowledge of Zero Trust concepts such as least privilege, micro‑segmentation, and continuous verification—and a curiosity to keep refining them.
• Authentication & authorization skills: Experience configuring and managing protocols like 802.1X, RADIUS, and TACACS+, with a focus on scalable and secure designs.
• Compliance awareness: Familiarity with security and privacy standards (e.g., GDPR, HIPAA, PCI DSS) and an ability to align NAC solutions with compliance needs.
• Threat detection & response: Ability to identify, analyze, and respond to threats such as malware, phishing, and denial‑of‑service attacks, including integration with SIEM platforms.
• Automation curiosity: Exposure to scripting, automation, or Infrastructure‑as‑Code approaches, with a willingness to grow skills around APIs and automation frameworks.
• Growth mindset: A proactive learner who enjoys solving complex problems, seeks feedback, and stays current with emerging security technologies and trends.
