As digital transformation accelerates, financial institutions face growing pressure to modernize their technology stack without compromising on security. Bank of the West, a prominent American bank, faced a critical challenge: how to secure its expanding footprint across AWS and Microsoft Azure while maintaining regulatory compliance, operational agility, and customer trust.
With increasing workloads hosted across multiple public cloud environments, the bank required a consistent and scalable approach to secure its infrastructure, detect vulnerabilities early, and enforce policy compliance without slowing innovation.
Embracing Infrastructure-as-Code for Scalable Security
To address this challenge, Bank of the West partnered with Trinet Technologies to architect and implement a future-ready security automation framework. At the core of this initiative was a transition to an Infrastructure-as-Code (IaC) methodology—codifying security configurations and cloud infrastructure into reusable templates and scripts.
This transformation empowered development and operations teams to:
- Automate provisioning of secure infrastructure
- Apply consistent security baselines across environments
- Minimize human error by eliminating manual configuration
- Maintain full version control and auditability across all deployments
By embedding security guardrails directly into the DevOps lifecycle, Trinet enabled the bank to adopt a shift-left security model, reducing risks early in the deployment pipeline.
A Holistic Security Strategy for Multi-Cloud Environments
Beyond automation, Trinet implemented a comprehensive cloud security architecture that spanned both AWS and Azure platforms. This included:
- Policy-as-Code implementation for real-time compliance checks
- Automated vulnerability assessments during provisioning
- Centralized identity and access management to control permissions
- Continuous monitoring tools for detecting anomalies and threats
- Secure CI/CD pipelines integrated with security checkpoints
In addition, Trinet conducted workshops with stakeholders across business and IT functions to define governance models, assign roles, and build a security-first culture across departments.
“Security in the cloud is not a product—it’s a mindset. At Trinet Technologies, we help financial institutions like Bank of the West design and scale secure multi-cloud architectures that adapt to change while maintaining trust, resilience, and compliance.”
Business Impact: Secure, Scalable, and Cloud-Native
The security modernization effort delivered measurable outcomes for Bank of the West:
- 70% reduction in manual configuration efforts through automation
- Faster deployment cycles with built-in policy enforcement
- Improved compliance posture across SOX, GLBA, and PCI-DSS standards
- Greater visibility and control over cross-cloud security risks
- Enhanced collaboration between security, dev, and ops teams
By transforming its cloud security posture, the bank has laid the foundation for scaling its digital offerings confidently, securely, and in full compliance with industry regulations.
