Security Vulnerabilities in Legacy Applications
Outdated codebases with known vulnerabilities and inconsistent security practices across development teams.
Integrating Security into the DevOps Pipeline
As digital businesses scale, the speed of software delivery must be matched by the strength of security measures protecting critical systems and customer data. A leading financial services provider partnered with Spundan to integrate security directly into its DevOps workflows — embracing DevSecOps to ensure that security, compliance, and governance become part of every build, test, and deployment.
The client operates complex, cloud-native applications that handle millions of sensitive transactions daily. While their CI/CD pipelines enabled rapid feature releases, security scans and compliance checks were performed manually and often late in the cycle — exposing the organization to vulnerabilities, compliance risks, and costly rework.
The implementation focused on three key pillars:
This document outlines the specific challenges faced, strategic implementation approach, measurable outcomes, and best practices derived from the organization's DevSecOps journey.
Before the DevSecOps initiative, the organization faced several critical challenges:
Security Vulnerabilities in Legacy Applications
Outdated codebases with known vulnerabilities and inconsistent security practices across development teams.
Late Security Checks
Security validation occurred only at the end of the development cycle, leading to last-minute issues and release delays.
Manual Vulnerability Scans
Security teams conducted scans and audits manually, increasing the risk of human error and overlooked threats.
Compliance Pressure
As a regulated financial institution, the client needed to meet strict data privacy and industry standards (e.g., PCI DSS, SOC 2).
Siloed Teams
Security was handled by a separate team, creating bottlenecks and gaps in developer awareness.
Spundan's DevSecOps experts worked alongside the client's engineering, operations, and security teams to build a secure, automated delivery pipeline that balanced speed with compliance.
Key solution elements included:
Security Integrated CI/CD Pipelines
Enhanced the client's existing pipelines to include automated static code analysis (SAST) and dynamic application security testing (DAST) at every merge and deploy step.
Infrastructure as Code (IaC) Security
Implemented policy-as-code tools to detect misconfigurations in infrastructure templates (Terraform, CloudFormation) before deployment.
Container Security
Integrated container image scanning tools to identify known vulnerabilities in base images and dependencies during the build stage.
Secrets Management
Introduced secure secrets management solutions to prevent hard-coded credentials and enable secure access to cloud resources.
Compliance Automation
Deployed continuous compliance tools that automatically generate reports for auditors, ensuring standards like PCI DSS and SOC 2 are met in real time.
Developer Enablement
Ran secure coding workshops and created reusable security playbooks, empowering developers to own security at every step.
The DevSecOps program was rolled out in three phases over five months:
Assessment & Planning
Reviewed existing pipelines, tools, and compliance obligations; defined security requirements for each workflow.
Pilot Integration
Integrated security checks into a selected application pipeline to validate performance and compliance impact.
Full Rollout & Training
Expanded secure pipelines across all services, trained developers and operations teams, and automated compliance reporting.
“With Spundan's DevSecOps framework, we ship features faster while knowing our security posture is stronger than ever. Our teams build security in — not bolt it on at the end.”
— Head of Security Engineering, Financial Services Client
After implementing the DevSecOps strategy, the organization achieved significant improvements in security posture, compliance, and operational efficiency:
90% of vulnerabilities detected and resolved before production through early scanning and automated blocking policies.
Zero release delays due to late-stage security findings.
Audit-ready compliance with continuous reporting for PCI DSS and SOC 2.
Higher developer confidence and stronger collaboration between security and engineering teams.
By embedding security into every stage of the pipeline, this financial services leader transformed its software delivery approach — achieving faster releases with uncompromised security and continuous compliance.
