AWS Post-Migration Security Validation

Moving workloads to AWS introduces a window of security exposure that many organisations only discover after an incident. PMSV is a fixed-scope, time-bound professional service that validates the security posture of your AWS environment following a migration, giving you an independent, evidence-based view of what is protected, what is misconfigured, and what requires immediate attention.

Delivered by Encyb Security Services — an AWS Advanced Tier Partner and Managed Security Services Provider — PMSV covers up to 100 compute resources (EC2 instances, containers, or virtual machines) and produces a prioritised findings report with remediation guidance mapped to the AWS Shared Responsibility Model and industry frameworks including CIS AWS Benchmarks and NIST CSF.

PMSV is designed to be completed within 10 business days of engagement start, providing a clear, actionable output without a long consulting runway. It is particularly suited to organisations in regulated industries — financial services, fintech, healthcare — who need to demonstrate security validation as part of their internal governance or regulatory obligations following a cloud migration.

What is covered:

• Identity and Access Management (IAM) review — over-privileged roles, unused credentials, cross-account access
• Network security configuration — security groups, NACLs, VPC exposure, public-facing assets
• Logging and monitoring coverage — CloudTrail, GuardDuty, VPC Flow Logs, coverage gaps
• Data exposure assessment — S3 bucket policies, encryption at rest and in transit Compute workload review — patch status, agent coverage, exposed services Findings report with severity ratings, risk context, and prioritised remediation steps

What you receive:
