Enterprise Security Platform (Securitas Global)

Summary

This cloud-based security access management platform modernizes multi-site access control by integrating RFID badge scanning, real-time authentication, and centralized role-based permissions into a highly secure AWS-powered system. By bridging legacy security hardware with cloud infrastructure, the platform enables instant access updates, real-time monitoring, and automated compliance logging, ensuring GDPR-compliant security operations. Built on Node.js and C# microservices, it seamlessly integrates with on-site RFID/badge scanners, while AWS Cognito and OAuth 2.0 authentication provide multi-tier authorization for employees, contractors, and security teams. With an intuitive React-based dashboard, security managers can grant, revoke, and audit access permissions across multiple facilities instantly. The system reduced manual security tasks by 60%, streamlined access for 1,000+ employees, and secured new high-value contracts for Securitas, proving its effectiveness in large-scale, high-security environments.

Challenges

• Managing access control for 1,000+ external employees across multiple facilities while ensuring top-tier security and real-time updates.
• High dependency on legacy security hardware that lacked cloud connectivity and centralized control.
• Lack of real-time access control logs made it difficult to track who accessed which facility and when.
• Inconsistent role-based permissions, leading to security gaps and manual intervention issues.

Solution

• Cloud-Based Security Management – Designed a modular AWS-based platform that connects on-site access control devices (RFID/badge scanners) to a centralized cloud dashboard, enabling remote monitoring and role-based user authentication.
• Real-Time Access Control Updates – Implemented a secure, event-driven architecture that propagates access changes instantly across all security checkpoints.
• Custom Role-Based Permissions & Multi-Tier Authorization – Developed granular user roles and security levels for security staff, facility managers, external contractors, and administrators.
• Automated Logging & Compliance System – Every access attempt, permission change, and security alert is encrypted and logged for auditability and compliance with GDPR and corporate policies.
• Security Manager Portal – Built an admin portal allowing security teams to configure access rules, revoke permissions, and monitor live entry logs across multiple locations.

Impact

• Enhanced facility security with real-time monitoring and instant access control updates.
• Successfully handled 1,000+ external employees, enabling seamless access across multiple sites.
• Reduced manual security tasks by 60%, saving time and minimizing human error in access management.
• Helped Securitas secure 5+ major new industrial security contracts per year, proving the platform’s effectiveness in high-security environments.
