At Quisitive Businesses LLP, I monitor and investigate security alerts with Wazuh and ManageEngine Log360, covering log analysis, alert triage, event correlation, and incident response.

I've deployed centralized SIEM monitoring across Windows, Linux, firewalls, and Syslog-enabled devices, while tuning detection rules, normalizing logs, and parsing JSON fields to improve security-event visibility. I also build Shuffle SOAR playbooks, including pfSense API integrations for automated malicious-IP blocking and security notifications.

I validate detections through MITRE ATT&CK-mapped adversary simulations and Atomic Red Team tests, and conduct VAPT, web application testing, and Active Directory penetration testing using tools including Nmap, Nessus, Burp Suite, Metasploit, and Kali Linux.
