I'm Bill Graham — a network and security architect with 30 years in the industry, currently at Cisco. I hold an active dual CCIE in Enterprise and Service Provider networking (#7258, recently past the 25-year milestone) and JNCIE-SP #119. My career has run through Juniper Networks, DriveNets, and Cisco — spanning service provider, cloud, and enterprise networking, with a focus on disaggregation, SSE, and Zero Trust security. This is where I write about the technical shifts I think matter most to our industry right now.
