About Me​
Hi, I’m Jackson Varghese, a Cybersecurity Architect with 14+ years of experience designing and delivering enterprise-scale cloud, identity, and data security architectures for large organizations in regulated industries.
My work focuses on Microsoft-centric security architectures, spanning Azure and hybrid cloud security, Identity & Access Management (Entra ID, CyberArk PAM), and Data Security / Data Loss Prevention (Microsoft Purview, Symantec DLP). I specialize in translating complex regulatory and risk requirements such as GDPR, NIS2, DORA, ISO 27001 into practical, scalable architectures that support both security and business operations.
​
I have led end-to-end security architecture initiatives for German enterprises supporting 300,000+ users, covering architecture design, implementation guidance, governance models, and audit-ready documentation (HLD, LLD, standards, and roadmaps). My approach emphasizes clarity, structure, and long-term maintainability, aligning security controls with real-world operational constraints.

What I Do​​
​
My core areas of expertise include:
-
Data Security & DLP
Designing and deploying enterprise DLP and information protection solutions across Microsoft Purview and Symantec platforms, protecting large user populations and sensitive data. -
Identity & Access Management
Architecting Zero Trust identity models, access governance, and privileged access management across complex enterprise environments. -
Cloud Security Architecture
Designing secure Azure and hybrid cloud architectures aligned with enterprise risk, compliance, and operational requirements. -
Security Operations & Integration
Integrating security architectures with SOC and SIEM environments (Splunk), improving detection, response workflows, and regulatory readiness. -
Compliance & Governance
Translating regulatory frameworks into implementable security controls and architectural patterns for enterprise environments.
​
My Approach​
I’m known for bridging the gap between technical security architecture and business decision-making. Rather than focusing on tools alone, I design security as a system, one that balances risk reduction, usability, compliance, and operational sustainability.
My work is documentation-driven, stakeholder-oriented, and aligned with how large organizations actually operate. I value structured processes, clear accountability, and pragmatic solutions over short-term fixes or theoretical models.

About This Blog
Cybersecurity is evolving faster than most organizations can comfortably manage. This blog is where I share practical insights drawn from real enterprise work, not vendor marketing or abstract theory.
​
Here, I focus on:
-
Making complex security and compliance topics understandable
-
Sharing lessons learned from large-scale security programs
-
Exploring how identity, data protection, and cloud security are reshaping enterprise risk
-
Helping security professionals grow with clarity, not hype
My goal is to make cybersecurity understandable, structured, and actionable—from boardrooms to hands-on practitioners.
​
Outside of work, I enjoy exploring new technologies, refining how security can be made more accessible, and continuing to improve my German (A2, in progress).
If you value clear thinking, practical security architecture, and long-term solutions, you’re in the right place.
