About Yogesh Mahajan

With 4 years in a dynamic cybersecurity role, I\'ve excelled as a results-oriented SOC Analyst. My experience includes round-the-clock monitoring of LogRhythm SIEM and Sophos & Microsoft Defender ATP for detecting and investigating security incidents, ensuring swift incident response and adherence to SLAs using Core5 Ticketing Tool. I possess strong skills in E-mail/Header Analysis, adept at identifying and mitigating spam and phishing threats reported by clients and through Office 365 ATP, thereby reducing user risk.A key aspect of my role involves integrating new log sources with SIEM, refining existing use cases, and developing new ones to enhance threat detection capabilities. I regularly produce reports such as ESM health reports, incident trackers, dashboards, and monthly decks, presenting detailed Root Cause Analyses (RCAs) of incidents during management calls. Knowledge Transfer (KT) sessions and the creation of SOPs and Playbooks ensure effective response to alerts and daily operations, promoting team efficiency and consistency.Collaboration with the Threat Intelligence team enables proactive monitoring by integrating Indicators of Compromise (IOCs) into SIEM and EDR systems. I also conduct quarterly audits to review and refine organizational security policies and conduct phishing simulations and user training to bolster awareness and resilience. Engaging in threat hunting activities, I analyze suspicious URLs and attachments in a sandboxed environment, using KQL commands to manage and mitigate potential threats effectively.Maintaining organized repositories for important reports and logs ensures accessibility and supports informed decision-making for clients and internal teams. Overall, my role is defined by proactive threat mitigation, continuous improvement of security practices, and ensuring robust defense against evolving cyber threats.
