From Zero Visibility to Board-Level Security Governance in 10 Weeks

LAMDA Development — listed on the Athens Exchange, recognised by TIME magazine as one of the world's 100 most influential companies, and the force behind The Ellinikon ($8B, 6.2M m²) — operates a Media Management Portal on AWS built by LCM Go Cloud to centralise tens of thousands of construction videos and pre-release marketing assets for the project.

This portal handles market-sensitive content whose unauthorised disclosure could directly affect the company's share price — a company that has raised €1.35B through capital markets since 2014. Yet after two years of portal development, the security posture had never been formally assessed. Misconfigurations, unencrypted volumes, and overly permissive IAM policies had accumulated. CloudTrail captured only bucket-level events — if a pre-release Ellinikon rendering was leaked, there was no way to trace who downloaded it, when, or from where.

With growing GDPR obligations, Athens Exchange governance requirements, and the Hellenic Capital Market Commission oversight, LAMDA Development needed to demonstrate cybersecurity due diligence to its audit committee — but had no compliance scores, no reports, and no audit trail to show.

LCM Go Cloud deployed a three-layer security architecture across approximately 10 weeks. Layer 1 established the AWS Security Baseline — KMS-encrypted CloudTrail with S3 data events and Insights, GuardDuty hardened to 1-hour finding frequency (from 6-hour default), Inspector v2 across 4 scan types, Security Hub with FSBP and CIS v3, and IAM least-privilege per team function — all codified in CloudFormation for the audit committee.

Layer 2 deployed CloudPosture — LCM Go Cloud's GenAI-powered CSPM platform — running 644 security checks via 19 specialised agents across 7 compliance frameworks (GDPR, ISO 27001, SOC 2, CIS v3/v5, NIST 800-53, FSBP). Amazon Bedrock (Claude) generates executable remediation plans in CLI, Terraform, or CloudFormation format. Toxic combination detection identifies high-risk misconfiguration chains. Weekly automated scans track compliance score trends for the audit committee.

Layer 3 secured the media assets directly: network micro-segmentation across web/app/data tiers, SSE-KMS encryption at rest for all 50+ TB of media files, role-based S3 bucket policies per team (press, IR, marketing, agencies), and CloudTrail S3 data events recording every file access — caller identity, source IP, timestamp — delivering complete forensic traceability for the first time.
