I’m Hayri Sezer and currently work for Netex as a Senior Network and Security Consultant for the Cisco Security and Arista Networks. I focus Network Security and Data Center Networking.

As a student of lifetime learning will be a pleasure to share my background.

Most of my career has been spent in the networking world, from a support engineer working for a Cisco partner to a senior network architect working for Netex which is the official distributor of Cisco. I also completed almost 3 years as an instructor at Offical Cisco Training Center

I have a strong technical background which I have validated with 6 certifications over my career, across multiple vendors (Cisco, Juniper, etc.).

I hold the Cisco CCIE certification, recognized as one of the toughest and remarkable certifications in the IT Industry.

To complement my technical certifications and expertise, I built solid enterprise architecture skills and have written business cases and devised complex network topologies.

I am a polished presenter and can articulate complex solutions from high-level to entry-level engineers. I regularly speak at events, whether on a large scale such as Cisco Webinars or at smaller forums such as local events.

Finally, I’m passionate about knowledge sharing and mentoring: I regularly train new hires and take the time to mentor individuals and companies across Cisco Security ecosystem.
