Reza Ghadir

I'm Reza Ghadir, a Network and Web Security Specialist focused on building infrastructure that stays secure under real-world pressure — not just on paper. Over 6+ years and 100+ projects, I've helped organizations in finance, healthcare, and enterprise build resilient networks, harden web applications, and close the gaps attackers go for first.

I started as a network engineer and was quickly drawn into security — pulled in by the idea that thinking like an attacker is what makes you a better defender. That path led me into firewall architecture, web application hardening, and security monitoring, along with exposure to SOC and NOC environments that broadened my view of where security operations fit into the bigger network picture.

Certifications like CCIE, CCNP Security, and Fortinet NSE 7 reflect a habit of staying current in a field that never stops moving — but what's kept me in this work is the problem-solving itself: finding where a system actually breaks, before someone else does.

• Designed network and security infrastructure for organizations across finance, healthcare, and telecom, with a focus on holding up under real attack conditions.
• Deployed and tuned Next-Gen Firewalls (Fortinet, Palo Alto, Cisco) with advanced threat protection.
• Secured 50+ web applications against OWASP Top 10 vulnerabilities.
• Designed and rolled out Zero-Trust architecture for distributed workforces.
• Conducted security audits for ISO 27001, NIST, and GDPR compliance.
• Implemented and tuned SIEM solutions for real-time threat visibility, before issues become incidents.
