About the role
S&P Global's Corporate Cybersecurity team protects the enterprise infrastructure behind its financial intelligence products. The network security function works with infrastructure, application, and security operations teams to secure connectivity and manage network risk. This role designs, implements, maintains, and improves controls across enterprise networks, including firewalls, VPNs, segmentation, and threat prevention.
What you will do
- Defend enterprise network boundaries by configuring, administering, and troubleshooting firewalls, security policies, NAT, and intrusion detection and prevention controls — directly reducing risk exposure across S&P Global's global infrastructure.
- Embed least-privilege security by implementing and maintaining network segmentation and access controls across internal, perimeter, and remote-access environments, ensuring every connection is intentional, documented, and justified.
- Enable secure global connectivity by supporting site-to-site and remote-access VPN services, including secure configuration, authentication integration, and end-to-end connectivity troubleshooting at enterprise scale.
- Govern network access risk by reviewing firewall and network access requests, validating business requirements, assessing risk, and removing obsolete or overly permissive rules — keeping the perimeter tight and audit-ready.
- Accelerate incident response by partnering with security operations during investigations, analyzing packet captures and device logs, and implementing approved containment and recovery measures.
- Build operational resilience by hardening network security devices, coordinating patching and firmware upgrades, remediating vulnerabilities, and automating repeatable configuration checks with appropriate review and safeguards.
