Built for Agility: Centizen’s Secure Access Framework with AWS STS

What stood out with Centizen was how quickly they understood our reality — distributed teams, sensitive content, and the need for speed. They built with us, not just for us.

A Worldwide Media and Marketing Company

A global marketing and content publishing organization with operations across multiple continents. The company relied on real-time access to reports, assets, and campaign data, but lacked a secure, scalable access model to support their hybrid workforce across devices and regions.

Centizen executed a phased engagement over 12 weeks to implement a secure, cloud-native access framework that aligned with Zero Trust principles. The project was delivered entirely by a remote, AWS-certified engineering team.

Phase 1: Discovery & Assessment

Centizen began with a comprehensive analysis of the client’s Citrix-centric infrastructure, current security practices, and fragmented identity workflows. Multiple stakeholder workshops were conducted to map user access flows, identify high-risk zones, and document role-based data needs. This ensured the proposed architecture would directly address operational pain points without disrupting business continuity.

Phase 2: Federated Identity Architecture

Centizen’s remote delivery team, comprising four AWS-certified cloud engineers and a cloud security consultant, designed a scalable access framework using AWS Security Token Service (STS) and IAM Identity Center. Temporary, federated Single Sign-On (SSO) access was provisioned based on role and session context, eliminating static credential risks.

Phase 3: Secure Access Layer Buildout

The team constructed secure bridges between Citrix-hosted digital assets and AWS-native cloud storage. Least-privilege IAM policies were embedded into STS credentials. In parallel, Centizen implemented multi-factor authentication (MFA), geo-location-based conditions, and session boundaries, ensuring identity context was always enforced at runtime.

Phase 4: Governance & Threat Monitoring

To establish full control and visibility, Centizen deployed AWS-native governance tools:

• CloudTrail for real-time event logging.
• IAM Access Analyzer for privilege audits.
• Amazon GuardDuty for continuous threat detection.

This architecture ensured security teams could proactively track and respond to access anomalies.

Phase 5: Production Rollout & Enablement

Centizen led a final rollout that included UAT, internal IT training sessions, and production cutover. Access policies were transitioned live without disrupting users. Teams were onboarded into new role-based access workflows with clear documentation, dashboards, and escalation support.

With a Zero Trust framework powered by AWS STS and federated SSO, the client now enjoys secure, real-time access to business-critical assets from anywhere.

Within 12 weeks, Centizen-appointed remote experts redefined how the client accessed sensitive information.

From identity federation to secure AWS integration, the project proved how Centizen’s talent solutions deliver long-term operational agility securely and at scale.
