Empowering organizations through robust Microsoft 365 security architectures, zero-trust implementation, and comprehensive threat defense utilizing Sophos and Entra ID frameworks.
Raphael is an IT Infrastructure & Cloud Security Engineer specializing in securing hybrid environments using Microsoft 365 and Sophos solutions. His work focuses on implementing Zero Trust principles across identity, endpoints, and data to strengthen organizational security posture.
He has hands-on experience with Identity and Access Management (Entra ID), endpoint protection, and data security using Microsoft Purview (DLP, Insider Risk Management, Information Protection). He is skilled in designing and managing secure, scalable infrastructure while improving threat detection and response capabilities.
The organization faced increasing security risks across identity, endpoints, cloud applications, and email systems. Users were vulnerable to phishing attacks, compromised credentials, anonymous IP access, and unauthorized cloud application usage. There was limited centralized visibility, no automated threat response, and security controls were fragmented across the environment.
To design and implement a unified security architecture using Microsoft 365 E5 Security solutions, enabling end-to-end protection, threat detection, and automated response across identity, endpoints, email, and cloud applications.
Problem: Disparate AV solutions across global branches causing alert fatigue and missed localized ransomware threats.
Solution: Rolled out Sophos Central with Intercept X across 300+ endpoints. Configured synchronized security with Sophos Firewalls to automatically isolate compromised nodes.
Outcome: Achieved 100% unified visibility into endpoint health and automated threat isolation, reducing incident response time to seconds.
Problem: Absence of structured classification for PII and IP, risking regulatory non-compliance during email transmission and external sharing.
Solution: Implemented Microsoft Purview Information Protection, creating auto-labeling policies for sensitive data across Exchange Online and SharePoint.
Outcome: Prevented data exfiltration incidents, ensured regulatory compliance, and provided comprehensive data flow auditing.
Problem: Enterprise environments had poorly structured networks, weak perimeter security, and limited visibility, failing to meet regulatory requirements.
Solution: Redesigned network architecture, deployed Sophos Firewall for perimeter protection, optimized routing and APs, and aligned with CBN compliance.
Outcome: Strengthened security and access control, improved network performance, enhanced traffic visibility, and supported regulatory compliance readiness.
Beyond implementing security architectures, I am passionate about elevating the industry's baseline knowledge. I coach a cybersecurity cohort on fundamental and advanced cybersecurity concepts, fostering hands-on technical skills and real-world implementation techniques.
Guided students through endpoint protection concepts including threat detection, attack surface reduction, and real-world security scenarios.
Conducted interactive workshops covering endpoint agent deployment, behavioral policy tuning, and ransomware mitigation tactics.
