Hey there 👋 I'm an AI Engineer with 7 years of experience building scalable web and mobile applications. Currently at Neurond AI (May 2025 — present), architecting an Enterprise AI Assistant Platform with multi-tenant RAG on pgvector, multi-provider LLM orchestration, and Azure-native infrastructure. Previously spent 5+ years at SNAPTEC (Sep 2019 — Apr 2025), leading SaaS themes, admin dashboards, and e-commerce platforms — earned the Hero of the Year award in 2021. I specialize in TypeScript, React, Next.js, and AI-Native engineering with Claude Code and Cursor.bio

Zero Trust Architecture Implementation Guide

Zero Trust Architecture implementation. Identity verification, microsegmentation, least privilege, continuous authentication.

Introduction

Zero Trust eliminates implicit trust in network architecture. Assumes breach, verifies every request regardless of location. NIST SP 800-207: all resources protected, all communication secured, access per-session with dynamic policy. Implemented through IAM, microsegmentation, endpoint security, continuous monitoring.

Never Trust Always Verify

Identity-Centric Security

Identity is the new perimeter. MFA mandatory with passkeys and FIDO2. IdPs: Okta, Azure AD, Google Workspace. ABAC determines authorization based on user, device, resource, environmental attributes. Policy engines evaluate in real-time.

Microsegmentation and Least Privilege

Divides network into isolated segments. Software-defined policies reference workload identities instead of IP addresses. Service mesh implements for Kubernetes with mTLS. JIT access grants temporary elevated access. Secret management with Vault, AWS Secrets Manager, Azure Key Vault.

Continuous Authentication

Evaluates session risk throughout based on behavior, device state, environmental factors. Risk signals: impossible travel, device compliance, unusual patterns. Adaptive access: low risk allows, medium requires step-up MFA, high denies. Implementations: Azure AD Conditional Access, Okta ThreatInsight.

Device Trust and Implementation Phases

Device compliance checks: OS version, patches, encryption, firewall. EDR monitors for threats. MDM manages configuration. Phased approach: Phase 1 deploy IdP with MFA and inventory. Phase 2 conditional access and PAM. Phase 3 microsegmentation and EDR. Phase 4 continuous auth and SIEM. Phase 5 automation.

Challenges and Lessons

Legacy apps: use identity-aware proxy. User friction: risk-based policies. Organizational resistance: involve teams in policy design. Tool sprawl: choose open standards. Cost: prioritize by risk. Start small, measure progress, iterate. Zero Trust is a journey, not a destination.
