//security engineer background
//who am i
hi, i'm Luís, a cybersecurity professional with 2 years of experience in security operations, firewall administration, and incident response. with a Computer Engineering background from Polytechnic of Guarda and a Postgraduate Diploma in Cybersecurity (CAS equivalent) from European University, i specialize in network security, ISO 27001 controls, and infrastructure hardening for enterprise environments.
currently working as a Security Engineer at Securnet since October 2023, and recently completed a Security Consultant role at JLP (December 2024 - July 2025). fluent in English and French, with immediate availability in Switzerland. proven ability to deliver measurable security improvements and respond effectively to critical incidents.
//my journey
internship at securnet
began my cybersecurity career with a 3-month internship (June - September 2023). configured firewalls, VLANs, and secure network segmentation. deployed and hardened servers (web, SFTP, email). integrated Zabbix, Grafana and GLPi for monitoring. applied ML clustering to reduce false positives in security alerts.
security engineer at securnet
promoted to Security Engineer (October 2023 - Present). configured FortiGate & Check Point firewalls (VPN, NAT, filtering). implemented IDS/IPS (Suricata) for network threat detection. developed Python-based VM disaster recovery solution achieving zero downtime. restructured client network post-breach.
advanced education & certifications
completed Postgraduate Diploma in Cybersecurity at European University with 19/20 grade (18 ECTS). earned Google Cybersecurity Professional Certificate, Fortinet Proactive Advanced EDR, and multiple Cisco CCNA certifications. strengthened expertise in security frameworks and compliance.
security consultant at jlp
engaged as Security Consultant (December 2024 - July 2025). achieved A++ security grade transformation (from F) via comprehensive audit. implemented TLS 1.3, security headers, and OWASP Top 10 controls. conducted penetration testing across multiple attack vectors. configured advanced access controls and IP restrictions.
mentorship & continuous growth
mentored 7 Bachelor thesis projects in cybersecurity. pursuing CrowdStrike Certified Falcon Responder (CCFR) and Splunk Core Certified User certifications. actively participating in AI/security hackathons and expanding skills in ML-based security solutions and threat intelligence.
//what drives me
proactive defense
security is not just about responding to incidents - it's about preventing them. i focus on building robust defenses through proper architecture, hardening, and continuous monitoring before threats materialize.
measurable impact
security improvements must be quantifiable. whether it's transforming an F-grade site to A++, achieving zero downtime with disaster recovery, or reducing false positives through ML - results matter.
continuous learning
the threat landscape evolves constantly. staying current with new attack vectors, security frameworks, and defensive technologies is essential. always pursuing new certifications and hands-on experience.
defense in depth
no single security control is sufficient. i believe in layered security - from network segmentation and firewalls to application controls, monitoring, and incident response capabilities working together.
//availability
currently open to Security Engineer, SOC Analyst, and Incident Response positions in Switzerland. especially interested in roles involving firewall administration, security operations, penetration testing, and security architecture design.
experienced with enterprise security technologies (FortiGate, Check Point, Suricata) and security frameworks (ISO 27001, OWASP, NIST CSF). fluent in English and French. available for both on-site and remote positions. immediate availability.
