I identified and remediated 12 critical level vulnerabilities through regular internal Penetration Testing exercises, directly preventing a potential data breach. I engineered a new enterprise Network Security policy that increased compliance adherence to 99.5% and successfully contained two sophisticated phishing campaigns. I implemented a Security Information and Event Management (SIEM) system that improved threat detection time by 50%.
