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

Migrations don't fail at the cutover. They fail six months later, when the controls you skipped become findings.

The migration is on the project plan. The security architecture usually isn't. Migrations get scoped against a business deadline, and the security review gets booked for after cutover by which point the landing zone is deployed, the identity boundary is drawn, and what should have been decisions are defaults you live with.

We sit inside the migration, not after it. Landing zone, identity model, segmentation, encryption, logging, and IR playbook are decided before the first workload moves and validated against your auditor's framework. Cutover confirms a secure architecture instead of exposing one that isn't.

Decisions made by default at cutover
01

Landing zone

Deployed before the security review means the defaults are now yours to live with.

02

Identity boundary

Drawn once, at speed, and inherited by every workload that follows.

03

Logging pipeline

What gets collected, retained, and monitored from the first day in production.

04

IR readiness

Who responds to an incident in an environment nobody has run yet.

Who this is for

Three situations where the migration is already in motion.

Situation 01

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.

The outcomeA landing zone, identity model, and observability baseline decided before the first workload moves, not bolted on after.
Situation 02

Acquired entity needs to consolidate

An M&A closed. 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.

The outcomeA scoped integration plan with controls mapped to the acquirer's framework, identity reconciled, and a regulatory obligation map for what the deal inherits.
Situation 03

Already on cloud, not audit-ready

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

The outcomeA retrofit plan that closes the audit-visible gaps in priority order, without re-platforming everything you already moved.
What's included

A migration that lands secure, governed, and audit-ready.

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.

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.

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.

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.

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.

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.

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.

How it works

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

Phase 01

Architect

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

You walk away with
  • A landing-zone design document.
  • An IAM and network architecture, written for review.
  • An encryption and key-management plan with the audit framework cross-referenced.
Phase 02

Migrate

Pre-cutover controls in place, runbooks reviewed, security architect in the war room. Data-in-transit protection, parallel-run validation, drift detection live during the cutover window.

You walk away with
  • A cutover runbook reviewed against the security architecture.
  • Telemetry flowing into the SIEM from the first cutover, not the first audit.
  • A migration risk register updated in-flight.
Phase 03

Validate

Post-cutover security testing against the design. Configuration drift assessed. Audit-evidence capture in place for the first reporting period.

You walk away with
  • A post-migration assessment report.
  • A first-period evidence base ready for the auditor.
  • A remediation list for any findings, with owners and due dates.
Phase 04

Operate

Handoff into ongoing cloud posture management, your team, your managed service, or our Managed Security Services. Observability tuned, alerting calibrated, framework evidence flowing into the running GRC program.

You walk away with
  • An operations runbook for the cloud environment.
  • Posture dashboards tuned to your risk profile.
  • A scheduled cadence for drift detection and re-validation.
Expertise this work draws on

The components behind a defensible cloud migration.

Cloud & Technology Infrastructure

Cloud Security Posture Management

Continuous configuration assessment across AWS, Azure, and GCP. The drift detection that catches the change your engineering team made on a Friday before it becomes the finding on Monday.

Cybersecurity & Compliance

Identity & Access Management

Federation, role design, privileged access, machine identities, and secrets management, the layer that absorbs the largest share of cloud incidents and the largest share of audit attention.

Technology & Security Operations

Logging & Audit Trails

Audit-grade logging across cloud control plane, workload, and application layers, retained and searchable for the windows your framework requires, and tuned for your SOC's detections.

Cybersecurity & Compliance

Compliance Framework Alignment

Control inheritance from the provider's attestations cross-referenced against SOC 2, HITRUST, HIPAA, PCI, and NYDFS, so the migration produces audit evidence, not just a working environment.
