What I'm looking for

I am seeking a role that fosters growth, innovation, and collaboration in cybersecurity.

I am a dedicated Cyber Security Analyst with extensive experience in SOC operations, network threat detection, and security automation. My journey in cybersecurity has equipped me with the skills to design, deploy, and manage security tools that effectively detect, prevent, and mitigate security threats in complex infrastructures. I thrive in dynamic environments and am committed to staying up-to-date on the latest security trends and best practices.

At Safaricom PLC, I have successfully monitored and performed in-depth investigations of real-time security alerts, utilizing SIEM solutions and the MITRE ATT&CK framework. My achievements include leading the deployment of Palo Alto Cortex SOAR, which significantly reduced incident response time by automating routine security tasks. I also collaborate with cross-functional teams to implement continuous security monitoring strategies, ensuring robust defenses against internal and external threats.

With a strong analytical mindset and excellent communication skills, I provide expert guidance on cybersecurity trends and emerging threats. I am passionate about leveraging my skills to enhance organizational security and contribute to a safer digital landscape.
