This project achieved compliance readiness in under 90 days—without slowing development.

Challenge

The client faced strict compliance requirements, limited visibility, and a high risk of lateral movement.

Solution

ECIS implemented a zero-trust architecture in AWS GovCloud with identity-aware access and centralized logging.

Overview

A critical zero-day vulnerability with active exploitation required immediate response across multiple cloud environments. The challenge was scale—identifying and fixing exposure faster than attackers could exploit it.

Solution

ECIS implemented a rapid-response framework:

  • Automated dependency scanning pipelines across all workloads
  • Prioritized remediation of internet-facing and high-risk systems
  • Integrated patching directly into CI/CD pipelines
  • Deployed WAF protections to mitigate active exploitation

Impact

  • Achieved full remediation of critical systems within 72 hours
  • Reduced future zero-day response time by over 60%
  • Established long-term visibility into software dependencies

Why It Matters

Zero-days expose gaps in both technology and process.
Automation ensures the next response is faster than the last.

Audit Visibility

Before

  • No visibility into vulnerable dependencies
  • Manual vulnerability identification
  • High exposure across internet-facing systems

After

  • Automated detection across all services
  • Centralized vulnerability tracking
  • CI/CD-driven remediation and validation
