I am a cybersecurity analyst specializing in threat detection and incident response.
What I'm looking for
I am a cybersecurity analyst with hands-on SOC experience in threat detection, incident response, and vulnerability management at financial and security firms. I am certified (CCNA, CCNP, Cisco CyberOps) and have worked with SIEMs and tools such as FortiSIEM, Security Onion, Wazuh, and Darktrace.
I have fine-tuned IDS/IPS rules to reduce false positives, automated vulnerability scanning with Nessus and custom scripts, and led forensic investigations using Wireshark, FTK Imager, and Autopsy to drive remediation. I prioritize pragmatic threat hunting, security automation, and clear reporting to strengthen detection and response capabilities.
