Cyber Security Architect

I'm a dedicated Cyber Security Architect and Engineer with a passion for building impenetrable defenses and resilient systems. I bridge the gap between complex threat landscapes and actionable security strategies.

My expertise spans Zero Trust Architecture, network segmentation, and cloud-native security. I thrive on adversarial thinking — understanding how attackers operate to build better defenses.

Based in Cuddalore, Tamil Nadu · Open to remote & on-site engagements.

🏗️

Security Architecture

Designing end-to-end security frameworks tailored to your organisation — from Zero Trust models to segmented network blueprints and control frameworks.

01
🔍

Penetration Testing

Simulating real-world attacks across web, mobile, APIs, and infrastructure. Actionable reports with risk-ranked findings and remediation guidance.

02
☁️

Cloud Security

Hardening AWS, Azure, and GCP environments. CSPM, IAM policy review, container security, and cloud-native SIEM integrations.

03
🚨

Incident Response

Rapid containment, eradication, and recovery for cyber incidents. Forensic analysis, root-cause identification, and post-incident hardening.

04
📋

Compliance & GRC

Aligning your security posture to ISO 27001, NIST CSF, PCI-DSS, SOC 2, and GDPR. Gap assessments, audit prep, and policy drafting.

05
🧠

Security Training

Tailored workshops for dev teams, SOC analysts, and executives. Threat modelling, secure coding, phishing awareness, and tabletop exercises.
