Dear Ms Walsh,
The recent cyberattack on Medibank that affected 9.7 million Australians highlighted the critical importance of proactive security engineering – exactly the type of challenge that drives my passion for cybersecurity. As an IT Security Engineer with four years’ experience implementing defence-in-depth strategies and achieving CISSP certification, I’m excited to apply for the Senior IT Security Engineer position at SecureTech Solutions.
In my current role at CyberGuard Australia, I’ve successfully reduced security incidents by 65% through implementing automated threat detection systems and developing comprehensive incident response procedures. My recent project involved designing and deploying a zero-trust architecture for a major Australian retailer, protecting over 200,000 customer records whilst ensuring PCI DSS compliance. I’m particularly experienced with SIEM platforms, having deployed and managed Splunk environments for clients across banking, healthcare, and government sectors.
My technical expertise spans vulnerability management, penetration testing, and security architecture design. I hold current certifications in CISSP, CEH, and AWS Security Specialty, and maintain active membership with (ISC)² and the Australian Information Security Association. Having worked extensively with Australian Privacy Principles and the Notifiable Data Breaches scheme, I understand the unique regulatory landscape that organisations face when implementing security controls locally.
I’m impressed by SecureTech’s commitment to advancing Australia’s cybersecurity maturity, particularly your recent partnership with the Australian Cyber Security Centre on threat intelligence sharing. I would welcome the opportunity to discuss how my experience in security automation and threat hunting can contribute to your team’s mission of protecting Australian businesses.
I’ve attached my portfolio demonstrating recent security implementations and would be delighted to discuss my approach to building resilient security architectures.
Sincerely,
Alex Thompson
