Hi, I’m Pavly George, a Network Security Engineer focused on designing, securing, and operating enterprise network infrastructures. I have a strong telecommunications background and hands-on experience delivering scalable, high-performance, and secure network solutions.
I have managed multi-vendor firewall environments including Cisco, Fortinet, Palo Alto Networks, and pfSense. My experience with Fortinet solutions covers FortiGate for next-generation firewalling, FortiManager for centralized policy and device management, and FortiAnalyzer for logging, monitoring, and security analytics. On the Palo Alto side, I have worked with Palo Alto firewalls and Panorama to centrally manage security policies, visibility, and operational performance across distributed environments and also with cisco ASA, FTD and FMC.
I am experienced in configuring firewall policies, site-to-site and remote-access VPNs, and implementing threat mitigation strategies to improve security posture and network performance. I have also managed TACACS+ access control using Cisco ISE and Segura PAM to centralize authentication and enforce secure administrative access.
Additionally, I have worked with F5 Load Balancers to optimize traffic flow, ensure high availability, and improve application performance, as well as administered SentinelOne for endpoint protection and Proofpoint as an email security gateway to reduce malware, phishing, and advanced threats.
I continuously develop my skills in network design, VLAN segmentation, and enterprise-grade projects using Cisco technologies, Microsoft Platforms and multi-vendor Firewalls using Network Emultion Progrms for professional network documentation and also I use Microsoft Visio, AutoCAD and Revit For accurate Network designs. My goal is to deliver efficient, secure, and future-ready infrastructure solutions that align with business and security requirements.
My Resume
We designed a Hospital Network and Security Infrastructure, specifying the locations for data outlets, telecom rooms (MDF and IDF), and structured the network infrastructure.

This project demonstrates secure VLAN segmentation with FortiGate as the gateway and DHCP server, enforcing MAC-based whitelisting to ensure only authorized devices receive IP addresses. Integrated with Cisco CME for VoIP and Active Directory for user authentication.
View DetailsI have hands-on experience in designing, securing, and operating enterprise network infrastructures. My work includes network topology planning, IP addressing, subnetting, VLAN segmentation, and ensuring secure and scalable network designs aligned with business requirements.
I have worked extensively with Cisco technologies, implementing VLANs, trunking, inter-VLAN routing, OSPF routing protocols, and switchport security. I also managed centralized authentication using TACACS+ with Cisco ISE to enforce secure administrative access.
I have experience administering Windows Server environments, including Active Directory, user and group management, DNS, DHCP, and system-level services. This enabled me to support enterprise authentication, authorization, and infrastructure services.
I have managed multi-vendor firewall environments using Fortinet, Palo Alto Networks, and pfSense. My responsibilities included configuring firewall policies, site-to-site and remote-access VPNs, threat prevention controls, and centralized management using FortiManager, FortiAnalyzer, and Palo Alto Panorama.
I worked with F5 Load Balancers to optimize traffic distribution, ensure high availability, and enhance application performance across enterprise environments.
I administered SentinelOne for endpoint protection to mitigate malware and advanced threats, and managed Proofpoint as an email security gateway to reduce phishing, spam, and email-based attacks.
I utilized GNS3 and PNETLab to build enterprise-grade network simulations for testing, troubleshooting, and skill development. I also created professional network diagrams and documentation using AutoCAD, Microsoft Visio, and Revit for projects such as Smart School and Smart City infrastructure designs.
I am currently enrolled in a German language course sponsored by the Ministry of Communications at KOMET Institut. The course offers certifications from A1 to C1 levels, supporting my professional communication and integration in international and German-speaking work environments.
