- Strong expertise in network security technologies, including VPN, firewalls, IDS/IPS, Zero Trust Network Access (ZTNA), and segmentation strategy and implementation.
- Technical proficiency in security solutions, including EDR, DLP, AV, email security, and cloud-native security controls.
- Experience implementing Zero Trust frameworks and network segmentation architectures in hybrid or multi-cloud environments.
- Understanding of Identity and Access Management (IAM) systems, including least-privilege access models, directory services, and policy-based access control. Familiarity with ITIL processes, security governance, and risk management, with experience tracking SLAs and compliance objectives.
Nice to Have Skills & Certifications
- Security certifications such as CISSP, CISM, CCSP, AWS Certified Security, or Cisco Certified CyberOps Professional.
- Experience with scripting and automation for operational efficiency (e.g., Python, PowerShell, Terraform), as well as modern Infrastructure-as-Code and Policy-as-Code frameworks.
- Familiarity with Zero Trust security models, segmentation technologies (e.g., SDN, NGFWs, NAC), and continuous risk assessment techniques.
