✅hi – I have done similar work, and I can already see how to contact it effectively. I can distribute a safe, well-structured network architecture with Firewall, VPN, IDS, and CCTV integration-you will expect an experienced network safety engineer with levels of catativity. I am a full stack engineer and hands-on project manager with 17 years of experience, which provides enterprise-grade network design, VoIP deployment and physical security system integration for commercial environment. In my opinion, the original of this project is a layered safety approach – a properly fragmented VLAN design, rigid firewall rules and IDS/IPS starting with integration. I will also configure a safe site-to-site VPN access, and ensure that Evaya and Grandstream phones work smoothly through QOS-managed traffic. It is similar to a multi-site office certification, which I completed, including Ubiquiti Firewall/VPN setup, Grandstream Intercoms, and Avaya IP Office System, all are tied in a managed Poe switching network with CCTV backhales and remote access. I need to know your favorite firewall brand (PFSENSE, Fortinet, etc.), Total device count and any remote access or monitoring requirements. Let’s cooperate. Thank you.
