AWS has published guidance on preventing data exfiltration by implementing egress controls across cloud workloads. Outbound traffic is frequently overlooked in cloud security postures, leaving organisations exposed to data theft via compromised workloads or misconfigured services. The article covers practical AWS-native controls to restrict and monitor what leaves your environment.

Security Architect’s Take: Audit your current outbound traffic posture now — apply VPC endpoint policies, restrict S3 bucket access using Service Control Policies (SCPs), and deploy AWS Network Firewall or a third-party egress filtering solution to detect and block unauthorised data flows before an incident occurs.
