Bio

I am a Cybersecurity Professional with a bachelor's degree in Computer Science Engineering and knowledge on SOC, CTI, GRC, and Responsible Gen AI. I have experience using SIEM tools, such as ArcSight and Splunk, to monitor, analyze, and respond to security events and incidents, protecting clients from cyber threats and minimizing risks.

As a Senior Security Analyst at HCL Technologies, I created and fine-tuned effective rules to capture real threat events and avoid false positives. I conducted in-depth analysis of security alerts and log data, collaborating with cross-functional teams to coordinate incident response efforts. I also provided extended support during the WannaCry ransomware exploit and trained junior team members as a Senior security analyst .

During my career break, While I have focused on my family, I have also remained dedicated and continued to up-skill in cybersecurity, focusing on GRC and AI in cybersecurity . Actively learning about emerging technologies and demonstrate a commitment to continuous professional development through webinars, conferences, and volunteer opportunities.

I am passionate about cybersecurity and eager to rejoin the workforce and leverage my skills and experience in a dynamic security environment.
