As a Cybersecurity IAM Developer at Tata Consultancy Services (TCS), I led the strategic redesign of Identity and Access Management for TechCorp, a global enterprise with 150,000+ employees. I transitioned the organization from fragmented, manual access methods to a unified, automated Zero-Trust architecture.
The primary objective was to secure TechCorp’s digital transformation by:
- Eliminating "orphan" account risks
- Enforcing Least Privilege
- Streamlining the user lifecycle across 100+ countries
TechCorp is a massive global entity struggling with a fragmented security landscape. Manual and inconsistent access management across 100+ countries created dangerous security gaps, such as "orphan accounts" from former employees, and operational bottlenecks that forced new hires to wait days for essential tools.
In a digital transformation, these manual processes cannot scale and leave the company vulnerable to multi-million dollar data breaches.
The primary goal of this simulation was to act as a Cybersecurity Consultant for TechCorp to achieve the following:
-
Master IAM Fundamentals: Gain a robust understanding of Identity & Access Management concepts and their critical role in securing modern, global enterprises.
-
Audit & Readiness Assessment: Formally evaluate TechCorp’s existing infrastructure to determine readiness for a large-scale IAM implementation.
-
Custom Solution Architecture: Craft tailored IAM solutions (automated provisioning, RBAC, MFA) that align with specific business processes to harden TechCorp’s security posture.
-
Strategic Implementation Planning: Develop a comprehensive, 6-month project roadmap that addresses complex integration challenges (Legacy, Cloud, and SaaS) while ensuring secure access to all digital resources.
My primary objective was to architect a centralized IAM Ecosystem that replaces manual effort with automation. By designing a framework utilizing:
- Role-Based Access Control (RBAC)
- Identity Governance (IGA)
- Modern Multi-Factor Authentication (MFA)
IT & Security Teams
- Automates "grunt work" like password resets and manual provisioning
- Frees the team to focus on high-level threat hunting
The Workforce (150k Employees)
- Modernizes the employee experience through self-service tools
- Provides "Day-1" access, boosting productivity
Company Stakeholders
- Ensures global regulatory compliance (GDPR/HIPAA)
- Protects proprietary assets from internal and external threats
- Security Architecture Design – Designing end-to-end workflows for user provisioning, de-provisioning, and self-service access.
- Risk & Readiness Assessment – Identifying security gaps in global infrastructure and mapping them to remediation strategies.
- Governance & Compliance – Aligning IAM controls with GDPR and HIPAA requirements and enforcing the Principle of Least Privilege.
- Technical Strategy – Developing multi-month implementation roadmaps including stakeholder management, resource allocation, and milestone tracking.
- Cross-System Integration – Planning the technical bridge between on-premise legacy systems, third-party apps (Salesforce), and Cloud environments.
Established the security pillars for TechCorp’s 150k-person attack surface.
- Focus: Identity Governance (IGA), MFA/SSO protocols, and Authorization logic
- Outcome: Defined the core framework required to protect TechCorp’s 150k-person global enterprise ecosystem
Analyzed TechCorp’s landscape to identify critical vulnerabilities and integration gaps.
- Key Findings: Identified risks such as orphan accounts, manual provisioning errors, and legacy security weaknesses
- Deliverable: Developed a 6-pillar Readiness Checklist mapping security and compliance (GDPR/HIPAA) needs
Insight: Below is a snapshot of the comprehensive 6-pillar audit checklist developed to evaluate TechCorp’s infrastructure and identify security maturity gaps. 📧 View Full IAM Readiness Assessement

-
Logic: Architected a global "Joiner-Mover-Leaver" lifecycle by designating the HR Database as the "Source of Truth" for automated provisioning.
-
Security Controls: Designed a hybrid RBAC/ABAC model with MFA enforcement and established a framework for Quarterly Access Certifications to ensure continuous compliance.
-
Tech Stack: Developed a unified ecosystem using ServiceNow for workflow orchestration and Okta/SailPoint for identity governance and cloud-to-on-prem synchronization.
