ABOUT OMOTOLANI ADETUNJI
As a dedicated cybersecurity analyst with over 4 years of experience, I specialize in protecting organizations from cyber threats through proactive monitoring, risk assessment, and incident response. My expertise spans security operations, compliance, and identity access management, enabling me to safeguard critical systems while driving process improvements. In my role at Expertedge Consulting Group, I managed security incidents by analyzing alerts from SIEM tools such as Splunk and ELK, ensuring timely remediation and escalation. I conducted internal risk assessments and security audits to maintain compliance with NIST, SOC 2, and HIPAA standards. Collaborating with IT teams, I enhanced security processes and delivered detailed executive reports to inform decision-making. Previously, as an Identity Access Management Analyst at Winteck NG Ltd, I managed IAM processes for over 200 users, implemented security best practices using Microsoft 365 and Azure, and reduced unauthorized access attempts by 45%. I also led security awareness programs to empower staff in maintaining secure practices. With certifications including CompTIA Security+, CySA+, and Microsoft Security Operations Analyst, I bring a solid technical foundation combined with strong communication skills. I excel in identifying emerging threats, implementing effective security controls, and guiding teams to build a resilient security posture. Passionate about advancing cybersecurity practices, I am committed to continuous learning and proactive defense strategies. Whether managing incidents, conducting audits, or mentoring junior analysts, I thrive on securing systems and driving impactful security initiatives.
