About

I am a Cyber Security Administrator with over three years of experience supporting vulnerability management, threat monitoring, security reporting, and cyber governance activities across large-scale environments. In my current role at the University of Essex, I help support security operations across more than 7,000 devices, using tools such as CrowdStrike, Nessus, and Lansweeper to monitor vulnerabilities, prioritise remediation, and strengthen the organisation’s overall security posture. I have contributed to significant improvements in patch compliance and reduction of actively exploited vulnerabilities, while also supporting monthly cyber security dashboards and KPI reporting using data from Maple and Barracuda reporting sources. My experience also includes monitoring emerging threats, including dark web monitoring, supporting policy compliance, and contributing to security awareness and phishing awareness initiatives. Alongside technical operations, I have been involved in cyber policy development, governance support, and user security awareness, giving me a broad understanding of both the technical and people-focused sides of cyber security. Previously, I supported the development and updating of cyber security policies and awareness training programmes, as well as contributing to Cyber Essentials-related compliance work. These experiences have strengthened my ability to communicate effectively with a wide range of stakeholders and support practical improvements in organisational security culture. I hold certifications in Cisco CyberOps Associate and Cisco Network Security, and I am currently completing an MSc in Cyber Security. I have also completed training and mock exam preparation for CompTIA Security+ and ISC2 Certified in Cybersecurity. In addition, I have working knowledge of frameworks including NIST, MITRE ATT&CK, CIS Controls, and ISO 27001 through both academic study and practical experience. I am now looking to progress into a Cyber Security Analyst or Cyber Security Specialist role where I can continue building on my experience in vulnerability management, threat monitoring, reporting, governance, and cyber resilience.
