Javier Liendo is a seasoned network and security consultant with 13+ years designing and defending enterprise and service provider infrastructures across L2/L3 and application-layer domains. His career spans roles at Cisco (including Technical Solutions Architect), Lucent, HP, and Smart Monkey Technologies, where he combines deep routing/switching expertise with hands-on web application and DNS security. Javier is a practical technologist who values the right tool for each job—equally comfortable deploying Anti-DDoS techniques, tuning NetFlow for threat detection, or hardening mod_security rulesets. He runs a Tor exit node and contributes to community Q&A, reflecting a privacy-minded, curious approach to real-world operational security. Based in Greater Mexico City, he pairs legacy protocol fluency (IPv4/IPv6, TCP/UDP, ARP/STP) with modern defensive practices on Linux/FreeBSD platforms. Quietly skeptical of hype, he brings pragmatic wisdom from years translating complex network problems into resilient, auditable solutions.
