ABOUT AISHWARYA AISHWARYA VANASANAVI VANASANAVI
I help organizations detect, analyze, and respond to real-world cyber threats by turning complex security data into clear, actionable decisions. With 3+ years of experience as a Security Analyst, I specialize in SIEM monitoring using Splunk ES and IBM QRadar, threat analysis, vulnerability assessment, and penetration testing across web, network, and mobile environments.My core strength lies in investigating security incidents end to end. I have handled phishing campaigns, EDR alerts, Active Directory security events, and suspicious network traffic by analyzing firewall logs and endpoint telemetry using tools like Tenable Nessus, Wiz, Microsoft 365 Defender, CrowdStrike, and Cisco AMP. In one recent case, I helped reduce recurring phishing incidents by 30% by improving detection rules and user awareness workflows.I started my career with a strong curiosity about how attacks actually happen in real environments, which drove me to focus on practical threat hunting and hands-on security testing rather than only theory. I’m known for being methodical, calm under pressure, and collaborative during incident response.I’m actively seeking opportunities in SOC, threat detection, and penetration testing roles and I’m open to relocate. Let’s connect to collaborate, share knowledge, or discuss security challenges.
