Cybersecurity, Firewall & SASE

· Administer Check Point firewalls, security gateways and related management platforms, including policy, objects, NAT, VPN, threat prevention, logs, upgrades, backups and high availability.

· Design and operate SASE capabilities covering secure web access, remote access, branch connectivity, identity-aware access, cloud application control and security policy enforcement.

· Support endpoint security products such as EDR/EPP, anti-malware, host firewall, device control, disk encryption, web protection and security posture enforcement.

· Review alerts, firewall logs and security events; investigate suspected threats and coordinate containment, remediation, evidence collection and escalation with SOC or security partners.

· Integrate corporate and guest wireless services with RADIUS/NAC, directory services, certificates and security policies.

Identity, Cloud & SaaS Integration

· Support network and security integrations with Active Directory and Microsoft Entra ID, including identity-based access, groups, RADIUS/NPS, SSO, MFA and conditional access dependencies.

· Support secure connectivity to Azure or other cloud environments using VPN, private connectivity, routing, DNS, network security controls and hybrid architecture principles.

· Enable and secure SaaS services through SSO, access policies, secure web gateway/CASB controls, logging and vendor integration requirements.

· Collaborate with server, cloud, application and security teams on changes affecting authentication, certificates, APIs, SAP/ERP, cloud workloads and business-critical services.

Service Operations & Incident Management
