Project Portfolio
Tagline: Cybersecurity
Project 1: Cloud Security Architecture for Financial Services
Client: Financial Services Company
Objective: Configured Zscaler ZIA for secure web access and Data Loss Prevention (DLP) measures to prevent sensitive data breaches. The approach included continuous verification of user identities and strict access controls to ensure only authorized personnel could access sensitive data. Conducted regular security assessments and audits to identify vulnerabilities and improve security compliance.
Key Technologies: Zscaler ZIA, Data Loss Prevention (DLP), Zero Trust, Multi-Factor Authentication (MFA).
Outcome: Achieved a 35% reduction in data breach risks, significantly improving the organization’s security posture and compliance with industry standards.
Project 2: Secure Remote Access Implementation
Client: Healthcare Organization
Objective: Configured a secure remote access solution using the WireGuard protocol, allowing remote employees to securely connect to cloud applications and internal resources. The implementation involved establishing a VPN with strong encryption (AES-256) and authentication mechanisms (public key cryptography) to protect sensitive data during transmission. Integrated OAuth for seamless user authentication, ensuring secure access while optimizing performance to reduce latency without compromising security.
Key Technologies: WireGuard, Multi-Factor Authentication (MFA).
Outcome: Enabled a 50% increase in productivity by allowing secure access from anywhere while maintaining stringent data protection.
