• Implementing IPSec and SSL VPN based solutions.
• Perform deep packet inspection to identify and mitigate threats in real-time.
• Identify and address network misconfigurations or design flaws to strengthen the overall security architecture.

• Proven experience with endpoint security tools (e.g., CrowdStrike, Carbon Black, or similar).
• 3+ years hands-on experience working with network security technologies: firewalls, VPNs, proxies, and DNS security solutions like Cisco Umbrella.
• Strong understanding of secure network architecture and protocols (e.g., TCP/IP, DNS, HTTPS, VPN).
• 3+ years Experience implementing and managing egress and ingress traffic filtering strategies, including split tunneling configurations.
• 2+ years hands-on experience with Software Defined Networking (SDN) is a significant advantage.
• 2+ years expertise in AWS-native security services (e.g., AWS WAF, AWS Shield, AWS Firewall Manager, AWS Network Firewall).
• Excellent communication and collaboration skills.
Nice-to-Haves
• Familiarity with cloud security frameworks and tools (e.g., AWS Well-Architected framework).
• Knowledge of regulatory frameworks such as PCI-DSS, GDPR, or ISO 27001.
• Experience with packet analysis tools (e.g., Wireshark, tcpdump) for troubleshooting and threat detection.
