Automating Cloud Security and Reducing MTTR to Seconds

Automated Security Remediation for a Global SaaS Enterprise

Implementing resilient automated security remediation is critical for high-growth software platforms handling sensitive enterprise data assets at scale. The client is an industry-leading Software as a Service (SaaS) provider delivering modern, AI-powered master data management solutions to Fortune 500 enterprises across healthcare, life sciences, financial services, and retail.

Operating across complex multi-cloud ecosystems, the client manages billions of real-time transactional records and mission-critical customer profiles. To fulfill the rigorous standards of an AWS Foundational Technical Review (FTR), the organization maintains a multi-account AWS architecture. Safeguarding this distributed infrastructure demands continuous compliance, proactive vulnerability mitigation, and zero configuration drift across every cloud tenant.

Desafio

Managing a large-scale, multi-account AWS footprint exposed the organization to critical operational friction and security risks:

  • Severe Alert Fatigue: The security operations team was overwhelmed by millions of alerts emitted by Prisma Cloud, making it impossible to separate critical exposures from low-priority noise.

  • High Mean Time to Remediation (MTTR): Addressing misconfigurations and non-compliant resources required continuous manual intervention, stretching remediation cycles to days or even weeks.

  • Continuous Compliance Exposure: Delays in manual remediation left sensitive cloud resources exposed, specifically over-permissioned IAM policies and misconfigured Amazon S3 buckets, jeopardizing FTR compliance milestones.

The organization required an intelligent, event-driven mechanism capable of delivering real-time automated security remediation across its cloud accounts.

A Estratégia

Crossjoin Solutions engineered a hybrid, event-driven remediation framework designed specifically for high-velocity multi-cloud operations. The architecture combined cloud-native security intelligence with AWS serverless compute to execute immediate corrective actions without human delay:

  • Real-Time Detection Ingestion: Prisma Cloud continued to serve as the core threat detection engine, identifying non-compliant resources and streaming security events directly to an Amazon Simple Queue Service (SQS) queue.

  • Serverless Automated Remediation: Incoming SQS messages triggered dedicated AWS Lambda functions configured with tailored mitigation logic to remediate policy violations and configuration errors instantly.

  • Autonomous Incident Governance: The pipeline automatically opened a Jira ticket upon alert ingestion, documented the technical details, and closed the issue autonomously once the AWS Lambda remediation executed successfully.

  • Multi-Cloud Scalability: The serverless architecture established a cost-effective, future-proof framework capable of scaling seamlessly across all current and future cloud environments.

Resultados de negócio e Principais Métricas

The introduction of automated security remediation transformed the client's security posture and daily operations. By replacing manual remediation tickets with serverless AWS Lambda execution, the enterprise reduced MTTR from days to seconds, closing attack vectors before misconfigurations could be exploited.

The engineering organization eradicated alert fatigue, unlocking significant developer productivity and streamlining operational overhead. Simultaneously, the automated integration with Jira established a bulletproof audit trail, ensuring continuous compliance with AWS Foundational Technical Review (FTR) mandates and safeguarding enterprise client data across the entire multi-cloud estate.
