Build on a foundation that's governed, secure, and ready to scale.
Every cloud initiative - security, compliance, cost control, velocity - runs on top of your AWS account structure. If that structure was never designed, everything built on it carries the risk.
CirOps implements the AWS Landing Zone Accelerator, an official AWS solution, to give your team a multi-account foundation with proper governance, automated guardrails, and centralized visibility - built correctly the first time.

The Problem
Ad hoc AWS growth has a ceiling.
AWS account structures can grow without a deliberate foundation. One account became three. Shared credentials became a security liability. Regions got provisioned without a network plan. By the time a compliance requirement or funding-round security review arrives, the gaps are structural.
Signs the foundation needs attention:
No account separation
Production, staging, and development share accounts, making cost attribution and blast-radius control impossible.
No guardrails
Engineers can provision any resource in any region, with no preventive controls in place.
Compliance blockers
No centralized audit trail, no account scoping for PCI, HIPAA, or SOC 2 requirements.
Cost visibility gaps
Cloud spend rises but cannot be attributed to teams, environments, or products with confidence.
Flat network design
Shared VPCs, open security groups, no controlled private connectivity between environments.
Identity sprawl
Multiple IAM users, no SSO, access managed manually across accounts.
These are not configuration errors. They are architectural decisions that were never made - and the longer they go unchanged, the more expensive they become to fix.
What We Deliver
A complete, governed AWS multi-account foundation.
CirOps delivers every layer of the landing zone - not just the initial setup.
AWS Organizations + OU Design
Account hierarchy designed around your environments, teams, and compliance requirements. Delegated administration configured correctly from the start.
AWS Control Tower and LZA
Control Tower supplies foundational account and governance capabilities. Landing Zone Accelerator adds configurable networking, security, and other resources. Control Tower and Landing Zone Accelerator are complementary, with the final configuration agreed for the environment.
Account Vending via Account Factory
Account Factory supports governed account provisioning through the approved account structure, ownership metadata, and baseline configuration.
VPC Design + Transit Gateway
Hub-and-spoke or segmented network topology built for your scale - private connectivity between accounts, no flat /16 sprawl, routing controlled and documented.
Identity Federation via AWS IAM Identity Center
Single sign-on connected to your existing identity provider - Okta, Azure AD, or Google Workspace. Centralized access management across every account.
Centralized Logging and Security Administration
The Log Archive account provides centralized log storage. Security services such as GuardDuty and Security Hub are administered through the designated Audit or delegated-administrator account, with findings aggregated for review.
Guardrails + Service Control Policies
Mandatory controls applied at the OU level. Teams retain autonomy within defined boundaries - without the ability to accidentally break the guardrails the business depends on.
Handover Package
Architecture documentation, runbooks, and a live enablement session with your engineering team. What we build, your team owns and understands.
Who It Is For
Built for teams at the foundation inflection point.
This engagement is the right fit if:
- You have 10 or more engineers on AWS and the account structure was never formally designed - it grew with the team.
- You've raised a funding round and the investor security questionnaire or due diligence process exposed gaps in your cloud posture.
- You're preparing for SOC 2, HIPAA, or PCI DSS and your current AWS environment doesn't support the required account separation and audit trail.
- Your cloud costs are rising but unattributable - you can't tell which team or product is driving spend.
- You're planning an AWS migration and need the foundation sorted before workloads move.
The landing zone is the right foundation for any AWS migration program - companies entering a formal migration engage this first.
How We Deliver It
Four steps from assessment to handover.
Discovery + Assessment
We review your current account structure, IAM posture, network topology, existing compliance requirements, and team size. We identify what migrates into the new structure and what, if anything, needs to be rebuilt. This step produces a scoped implementation plan with a clear timeline before work begins.
Architecture Design
We design your AWS Organizations OU hierarchy, network topology, identity model, and guardrail policy set. Your engineering lead reviews and approves the design before implementation starts - no surprises mid-engagement.
Implementation
Control Tower provides the foundational landing zone and Landing Zone Accelerator adds the approved configuration through AWS CDK and CloudFormation. Account Factory, identity, networking, logging, and delegated security administration are implemented in sequenced milestones.
Documentation + Team Handover
Architecture documentation is generated from the deployed state and refined by our engineers - not recreated from memory. Runbooks cover the operational procedures your team needs day one. A live handover session closes the engagement.
Our Approach
AI-assisted delivery, with engineer review.
CirOps engineers use AI-assisted tooling during landing zone delivery. AWS CDK and CloudFormation changes for account structure, OU hierarchy, guardrails, and network topology can begin from assisted drafts, then are reviewed and validated by engineers before any apply runs. Architecture documentation is generated from the deployed state, not assembled from notes.
The deployed state remains the source for reviewed documentation and handover materials.
