Cloud Migration Security Advisory
Move with confidence. Pre-migration risk assessment, secure landing zone deployment, and post-migration configuration audit — for AWS, Azure, and GCP migrations.

End-to-end cloud migration security — from pre-migration workload risk assessment through secure landing zone deployment and post-migration configuration audit.
Pre-Migration Risk Assessment
Assessing the security posture of your on-premises workloads before migration — application dependency mapping, data classification review, legacy vulnerability assessment, and migration risk scoring to identify which workloads are safe to move and which need remediation first.
- Application dependency mapping and risk scoring
- Data classification review (PII, sensitive, regulated)
- Legacy vulnerability assessment of candidate workloads
- Migration risk scoring and sequencing recommendation
Secure Cloud Landing Zone Design & Deployment
Designing and deploying a secure Landing Zone before your first workload arrives — AWS Control Tower, Azure Landing Zone, or GCP Landing Zone with pre-configured SCPs, Azure Policy guardrails, centralized logging, network foundation, and identity federation.
- Cloud account / subscription / project structure design
- Shared security services setup (SIEM, WAF, DLP)
- Network foundation (VPC, Hub-and-Spoke, firewalling)
- Identity federation setup (SSO, MFA, RBAC)
Migration Execution & Post-Migration Audit
Security oversight through the migration execution phase — ensuring data is encrypted in transit, migration agents have minimal privileges, no new attack surface is created during the move, and a post-migration configuration audit validates the landed workload against the security baseline.
- Migration wave planning and security sign-off
- Data transfer encryption and channel security
- Post-migration cloud configuration audit
- Security acceptance testing and baseline validation
The Migration Window Is the Highest-Risk Period in Cloud Adoption
Cloud migration introduces a window of elevated security risk — migration agents with broad access, data in transit over external channels, temporary firewall rules, and the rush to meet migration deadlines. Configurations made temporarily during migration have a persistent habit of becoming permanent.
A security-first migration approach starts with the landing zone, not the first workload. We help you build the right foundation before anything moves — so every migrated workload lands in a secure, compliant, and auditable cloud environment.
Lift & Shift Risk
Migrating vulnerable workloads without remediation introduces pre-existing CVEs into your cloud environment.
No Landing Zone
Workloads deployed before a landing zone is built create security debt that takes 12-18 months to remediate.
Migration Agent Scope
Overly-broad migration agent credentials — common under deadline pressure — create persistent access risks.
Data Classification Gaps
70% of organizations discover sensitive data in workloads not initially flagged as sensitive before migration.
5-Phase Cloud Migration Security
From workload discovery and landing zone deployment through wave-by-wave migration oversight and post-migration compliance audit.
Migration Scope & Workload Discovery
Documenting all candidate migration workloads — applications, databases, and infrastructure — including their dependencies, data classifications, current security controls, and compliance requirements. We produce a migration candidate registry with risk scores and recommended sequencing.
Secure Landing Zone Design & Deployment
Designing and deploying the cloud landing zone before any workload migration begins. We configure the account structure, SCPs and guardrails, centralized logging, network foundation (hub VPC / transit gateway / VNet), shared security services, and identity federation — ensuring the cloud environment is security-hardened before it receives workloads.
Migration Security Architecture for Each Wave
For each migration wave, defining the target architecture in the landing zone, reviewing the migration pathway security (encryption in transit, credential scoping for migration agents), and identifying any pre-migration remediation required on the source workload.
Migration Execution Oversight
Security review and sign-off for each migration wave — verifying that data transfer channels are encrypted, migration agent credentials are scoped to minimum required permissions, and temporary firewall or route table changes required for migration are tracked and reversed post-migration.
Post-Migration Audit & Compliance Validation
Post-migration configuration audit of each landed workload against the cloud security baseline — verifying encryption at rest, network access controls, IAM permissions, logging coverage, and patch status. Findings are mapped to compliance controls (SOC 2, ISO 27001, PCI-DSS) relevant to each workload.
End-to-End Migration Security Coverage
From workload risk assessment and secure landing zone through identity federation, data transfer security, post-migration audit, and compliance mapping.
Workload Risk Assessment
Assessing each migration candidate for security risks, data sensitivity, dependency complexity, and compliance requirements — producing a risk-scored migration backlog that sequences workloads from lowest to highest risk.
Secure Landing Zone
AWS Control Tower, Azure Landing Zone, or GCP Landing Zone deployment with pre-configured SCPs, Azure Policy, or GCP Org Policies — ensuring every workload lands in a secure, compliant cloud environment from day one.
Identity Federation
Configuring federated identity from the enterprise IdP (Entra ID, Okta) to the target cloud platform — enabling SSO, MFA enforcement, and least-privilege RBAC for all landing zone resources before the first workload arrives.
Data Transfer Security
Reviewing and configuring the security of data transfer channels — AWS DataSync, Azure Data Factory, Database Migration Service — ensuring data is encrypted in transit with strong protocols and transfer credentials are minimally privileged.
Post-Migration Audit
Configuration audit of each migrated workload against the cloud security baseline — encryption at rest, security group / NSG rules, IAM permissions review, CloudTrail / Activity Log coverage, and patch status verification.
Compliance Mapping
Mapping post-migration configuration findings to compliance controls (SOC 2 Type II, ISO 27001, PCI-DSS, HIPAA) — producing audit evidence that demonstrates the migrated workload meets its compliance requirements in the new cloud environment.
Land Before You Launch — Every Time
We design the secure foundation before the first workload moves. Security-first migration means every workload lands in a hardened environment — not a cloud account that was set up in a hurry.
Land Before You Launch
We design and deploy the secure landing zone before any workload migration begins — not in parallel with the first wave. This prevents the 18-month remediation cycle that follows cloud migrations done in the wrong order.
Risk-Sequenced Migration
Our pre-migration risk assessment produces a sequenced migration backlog that moves lower-risk workloads first — validating landing zone security with non-critical assets before migrating regulated and sensitive data.
Migration Window Security
The migration window introduces temporary elevated credentials, open firewall rules, and data in transit — all of which are high-value attack targets. We maintain security oversight through the entire execution phase, not just before and after.
Compliance-Integrated
Migration security is designed with the end-state compliance requirements in mind from day one — SOC 2, ISO 27001, PCI-DSS, and HIPAA controls are built into the landing zone and post-migration audit, not added after the fact.
