Praveen Raja

As a recent graduate with a Master's in Applied Cyber Security from Queen's University Belfast, I'm fueled by my passion for protecting our digital world. Over the past 5+ years, I've gained hands-on experience in various security domains, tackling challenges in risk analysis, incident response, network security, and change management.

Armed with expertise in LogRhythm SIEM/SOC and Tenable products (Tenable.SC, Tenable.OT & Tenable Nessus), I thrive in high-pressure environments, finding solutions to critical problems and delivering projects successfully. I'm proficient in cloud and AI technologies allowing me to approach security with a holistic perspective.

Contributing to the UK's robust cybersecurity and Support landscape excites me. I'm constantly seeking to deepen my knowledge and collaborate with talented minds. If you're passionate about innovation and building a more secure future, let's connect! I'm eager to discuss exciting new ventures and explore potential collaboration opportunities.
