MAELO

As a Cybersecurity Specialist, I monitored and responded to security incidents using SIEM tools like Splunk and Sentinel. I conducted regular vulnerability assessments and penetration tests with Nessus and Nmap, and implemented firewalls, VPNs, and IDS/IPS systems to protect networks. I developed and enforced security policies aligned with NIST and ISO 27001 standards and led employee training on cybersecurity best practices. I played a key role in incident response planning and cloud security reviews for AWS and Azure environments. Notably, I reduced phishing response times by 50% through automation and improved threat detection by migrating the SOC to a cloud-based system. My role required close collaboration with IT and compliance teams to ensure risk mitigation and regulatory alignment, while using tools such as Wireshark, Python, and PowerShell daily.
