The migration date is set. The threat model isn't.

Cloud migration is an architecture decision and a security decision at the same time. We sit inside the migration (landing zone, identity, network, data-in-transit, observability) so the cloud you cut over to is the cloud your auditor, your regulator, and your customer can sign off on.

Why This Matters

Cloud migrations don't fail at the cutover. They fail in the six months after, when the controls you didn't carry over become findings, breaches, and unbudgeted remediation.

The migration is on the project plan. The security architecture usually isn't. Cloud migrations are scoped against business deadlines (a data-center exit, a customer commitment, an M&A integration) and the security review gets booked for after cutover. By then, the landing zone is already deployed, the identity boundary is already drawn, and the things that should have been decisions are now defaults you have to live with.

We sit inside the migration, not after it. The landing zone, identity model, network segmentation, encryption baseline, logging pipeline, and IR playbook are all decided before the first workload moves and validated against the framework your auditor uses. Cutover is a confirmation of a secure architecture, not the moment you discover the architecture wasn't secure.

99%

of cloud security failures through 2026 are projected to be the customer’s fault, driven entirely by preventable misconfigurations, identity flaws, and data exposure on their side of the shared responsibility model.

Three situations where the migration is already in motion.

Who This Is For

Situation 1

First major move to
public cloud

Data center exit, a customer commitment, or a board mandate is driving a first-time move to AWS, Azure, or GCP. The migration plan exists. The security architecture is a footnote in it.

Situation 2

Acquired entity needs to consolidate

The acquired entity runs on a different cloud, a different identity provider, and a different audit framework. The acquirer's security team needs the integration done in a window that's already too short.

Situation 3

Already on cloud, not audit-ready

An auditor, customer, or new regulation is asking questions the current configuration can't answer. The original migration prioritized speed over evidence.

Best Outcome

A landing zone, identity model, and observability baseline decided before the first workload moves, not bolted on after.

Best Outcome

A scoped integration plan with controls mapped to the acquirer's framework, identity reconciled, and a regulatory obligation map for what the deal inherits.

Best Outcome

A retrofit plan that closes the audit-visible gaps in priority order — without re-platforming everything you already moved.

Six phases, with each producing an artifact a security architect, an auditor, or a regulator can read.

Cloud migration as a security engagement, not a security audit. Each phase produces a written deliverable (landing-zone design, IAM model, key-management plan, observability blueprint, cutover runbook, post-migration assessment) that fits in the program your auditor reviews and the cloud operations team runs after handoff.

How It Works

Phase 1

Discover

Current-state inventory, data classification, system dependency map, and the regulatory obligations the workload carries today and will carry post-migration.

Phase 2

Design

Landing zone, identity boundary, network segmentation, encryption baseline, secrets and key-management model designed against your audit framework, not a generic reference architecture.

Phase 3

Prepare

Pre-migration controls in place: IAM roles, network policies, baseline logging, IR playbook updates for cloud, runbook for cutover and rollback, key-management ceremony.

Phase 4

Migrate

Data-in-transit protection, parallel-run validation, drift detection during cutover. Security architect in the cutover war room, not on Slack.

Phase 5

Validate

Post-cutover testing, configuration drift detection against the design, compliance-evidence capture, and the first-quarter audit-readiness pass before the period closes.

Phase 6

Operate

Handoff to ongoing cloud posture management. Observability tuned, FinOps and SecOps integrated, framework evidence flowing into the running GRC program.

The blueprint for your secure cloud landing zone.

What's Included

After this engagement, you will have:

A secure landing zone, by design

Account or subscription structure, organizational policies, baseline guardrails, and tenant boundaries written to AWS, Azure, or GCP guidance and to the audit framework your environment reports against.

After this engagement, you will have:

An IAM and access architecture

Identity provider integration, role hierarchies, break-glass procedures, machine identities, and secret-management strategy. Privilege boundaries that hold up under a least-privilege audit.

After this engagement, you will have:

A network and segmentation model

Network architecture (VPC/VNet design, subnets, peering, egress controls), zero-trust between tiers, and the inspection points your SOC will need to see traffic at.

After this engagement, you will have:

Data-in-transit and at-rest protection

Encryption baselines, key-management decisions, data classification applied to the migration, and the DLP scope for the migration window itself.

After this engagement, you will have:

Observability stood up day one

Logging, metrics, and alerting wired into the SIEM before cutover not after. The first quarter of cloud telemetry is captured against a real baseline, not reconstructed.

After this engagement, you will have:

A migration risk register

Every architecture decision with its risk, its mitigation, and its residual exposure on paper. Reviewed with your security lead, ready for an auditor or a board.

After this engagement, you will have:

A handoff into cloud posture management

Whatever you stood up here flows into the team or service that operates it. One control set, one evidence base, one source of truth for the cloud environment going forward.

Six layers. The cloud provider owns some, you own some, and the rest is the work.

Every cloud provider publishes a shared-responsibility model. None of them tell you, for your environment, on your migration timeline, exactly which controls fall to your team. That mapping is the work, and it's where most cloud security programs end up with a gap.

Shared Responsibility, Made Specific

Identity & Access

Federation, role design, least-privilege boundaries, secrets management, machine identities, break-glass. Almost entirely yours, and the leading source of cloud breaches.

Network & Perimeter

VPC/VNet topology, segmentation, egress control, private connectivity, inspection points for your SOC. Shared at the fabric level, yours at the design level.

Data Protection

Classification, encryption keys, retention, residency, DLP. The provider gives you the primitives; the policy and the evidence are yours.

Workload Configuration

Hardening, patching, image baselines, container security, serverless permissions. Yours, with provider-native tooling that's only useful when it's configured against a baseline.

Identity & Access

Federation, role design, least-privilege boundaries, secrets management, machine identities, break-glass. Almost entirely yours, and the leading source of cloud breaches.

Observability & Detection

Logging pipelines, retention, SIEM integration, alerting, threat detection rules. The provider emits the events; the pipeline and the detections are yours.

Compliance & Evidence

Control inheritance from the provider's attestations, then the controls you have to operate on top and the evidence cadence that proves you ran them.

Four phases. Scoped to the migration plan and its cutover date, not to a standard engagement length.

How It Works

Phase 1

Architect

Landing zone, identity, network, encryption, and observability decided before the first workload moves. Designed against the audit framework your environment reports against not a generic reference architecture.

Phase 2
