Mariano Guillén

I’m a senior infrastructure and cybersecurity specialist with multidisciplinary experience across enterprise networking, VoIP systems, satellite communications, digital forensics, malware analysis, systems administration, and operational security. I design, deploy, troubleshoot, and secure complex IT environments—covering telecom infrastructure, Windows/Linux servers, network security appliances, virtualization platforms, and remote operational systems.

I’m comfortable working independently in remote environments, handling architecture, deployment, operations, documentation, and incident analysis end-to-end. Since 2010, as a Government Infrastructure & Cybersecurity Consultant, I’ve implemented firewall policies, segmentation strategies, VPN connectivity, and operational hardening, and I’ve built internal automation workflows for monitoring, reporting, and evidence generation—plus digital forensics and malware analysis support. I also designed IoT operational monitoring prototype concepts using LoRaWAN and industrial telemetry, and managed Linux-based VPS infrastructure with Dockerized services, reverse proxies, logging systems, and remote administration.
