AWS Landing Zone · Continuous compliance

Every control,
under control.

TowerControls is one platform to operate your AWS landing zone, run every compliance control, and prove continuous compliance — live NIST 800-53 posture scored to FedRAMP, SOC 2, ISO 27001, HIPAA and more, with AI that drafts the work and every change deployed through a reviewed pull request. All from one console-free control plane.

Continuous compliance

Compliant in January. Compliant in July.
Compliant the day of your assessment.

Most teams scramble for weeks before an audit. TowerControls reads your live NIST 800-53 posture every single day, drafts the evidence and the fix as it drifts, and keeps your audit package current — so you're audit-ready all year, not just the week before. It scores every framework off that one read — SOC 2, ISO 27001, PCI and HIPAA for commercial; FedRAMP, CMMC and OSCAL for federal — with a coverage matrix that shows exactly which controls are proven and which still need evidence. One assessment, many authorizations. All in your own account, so nothing ever leaves.

✓ One scan → SOC 2 · ISO 27001 · PCI · FedRAMP · CMMC ✓ Coverage matrix — proven vs. still-needs-evidence ✓ Shared-responsibility split — AWS-inherited vs. yours ✓ Audit-ready (Commercial) · ATO-ready with OSCAL (Government)

The Control Surface For AWS Landing Zone Accelerator
The old way

A landing zone is governed by code. Operating it by hand is the bottleneck.

AWS Control Tower and Landing Zone Accelerator put your whole org into YAML — then leave you to edit it by hand, across seven files, behind a maze of consoles.

▲ Without TowerControls

  • ✕ Hand-edit accounts-config, iam-config, security-config… and hope the schema is right.
  • ✕ Click through the AWS console across Organizations, IAM, Identity Center, Control Tower.
  • ✕ Catch mistakes only after a 45–90 min pipeline run fails.
  • ✕ Audit drift and readiness by hand, account by account.
  • ✕ Run a cross-org migration off a bespoke 90-day runbook.

◆ With TowerControls

  • ✓ Fill a form. It writes valid YAML and opens the pull request for you.
  • ✓ One control surface reads it all, cross-account, read-only.
  • ✓ Validates before the pipeline — schema errors caught up front.
  • ✓ Drift, readiness and SCP slots on demand, in one click.
  • ✓ The migration runbook is the app: inventory → move → baseline → enroll.
One control surface

See everything. Propose anything. Touch nothing without your merge.

01 · SEE

Live state, read-only

Accounts, OUs, roles, groups, SCP slots, declared-vs-live drift, account readiness, and the live pipeline — assumed cross-account with least-privilege read access.

02 · PROPOSE

Every change is a PR

New accounts, access grants, migrations — each renders the exact YAML diff, dry-runs first, then opens a feature-branch pull request. Append-only guardrails, fully audited.

03 · MERGE

The human owns the gate

TowerControls never merges and never starts the pipeline. You review the branch, you merge to main, and the Accelerator pipeline does the rest.

The platform

One platform. One governed pipeline.

TowerControls is the platform, and everything in it is used together: GitZero is the surface every change enters through, and the AWS landing zone is the substrate it governs — both live inside the platform. Beside them, ATO Now turns everything they do into an authorization package you can sign. Every landing-zone change flows through them as a single, policy-gated pipeline.

🛡Govern · the brain

TowerControls

the policy & compliance plane

The brain that knows whether a change is safe and whether the org is compliant. It operates the landing zone, runs a continuous compliance program, and owns the policy gate every change passes — in two editions from one codebase.

  • Operate accounts, OUs, access, migration — no console
  • DevSecOps — vend a software factory + deploy its platform
  • Live posture & frameworks — FedRAMP / NIST (Government) · SOC 2 / ISO / PCI (Commercial)
  • The change-policy gate + break-glass + full audit
  • Console access, quotas, backup/DR, org-wide search
  • AI on every screen — scorecards, triage, remediation, drafting
Inside the platform · used together
🔀Build · the surface

GitZero

gitzero.towercontrols.ai

A complete, GitLab-style workspace over AWS CodeCommit — not just a repo browser. Landing-zone changes start here as a pull request, with the TowerControls compliance verdict shown right on the proposal and the merge routed through the gate.

  • Repos, file tree, diffs, branches, releases
  • Proposals with line-level review, approvals & merge (fast-forward / squash / 3-way)
  • A security scan on every proposal — secrets & IAM findings
  • Review apps — a live preview of the branch, on demand
  • Tickets (kanban) + DORA delivery metrics: ticket → PR → pipeline → release
  • Pipelines, environments, container registry, audit log
🏗️Run · the substrate

The Landing Zone

AWS Control Tower + Landing Zone Accelerator

AWS's own governed landing zone — the substrate the others drive. It's already declarative: a config repo feeds the Accelerator pipeline that provisions and enforces the org. GitZero is its front end; TowerControls owns the writes.

  • The aws-accelerator-config repo
  • The AWS Accelerator deployment pipeline
  • Guardrails, baselines, and enrolled accounts
  • Security Hub / Config / GuardDuty evidence
✅Authorize · the proof

ATO Now

the authorization capstone · Government edition

The readiness gate for an Authorization to Operate. Nine gates are checked against the live org — verify a gate and watch it flip green in place — and the moment nothing is failing, it produces the authorization package.

  • Nine live gates — foundation, posture, coverage, POA&M, policies, third-party, ConMon, OSCAL, system inventory
  • Every gate says exactly what's missing — and links to where to fix it
  • POA&M auto-draft turns failing controls into tracked, dated items
  • Full document set on green — SSP · SAR · POA&M · coverage · posture, as OSCAL — plus an AI-written review for the AO
  • Per-application packages — a FedRAMP scorecard and OSCAL bundle for each registered app
  • An authorization recommendation: authorize · with conditions · not ready
How they work together — one change, end to end

ATO Now · Gov

The gate runs the same policy engine twice — early on the proposal for instant feedback, and again to enforce at the merge — so a change is checked whether it originates in GitZero or in TowerControls, and it fails closed: if the brain can't answer, the change doesn't move. One shared sign-on links GitZero and TowerControls, so a person moves between the surface and the brain without a second login.

DevSecOps · one-touch

Stand up a software factory — then a running platform.

Two gated moves take a team from nothing to a private, internal-facing platform. Vend tenant creates the governed accounts; Deploy platform fills one with a running cluster — built foundation-first, air-gapped, and delivered as one reviewed pull request. Nothing is created until you merge.

VEND TENANT

A tenant in one PR

A tooling account plus one account per environment, each isolated in its own OU. One reviewed pull request stands up the whole factory — and Merge & run deploys it in a click.

CHECK READINESS

Image checks, scored

Before you vend, TowerControls reads the container images of a pipeline you already run and scores four gates — the registry itself, scan findings, signing, and a software bill of materials — mapped to the controls a reviewer asks about.

DEPLOY PLATFORM

Private & air-gapped

A private-endpoint container cluster on an internet-isolated network, with the delivery controller mirrored into your own private registry. Infrastructure stays declarative; your apps stay in the repo you own.

Inside the factory

One merge. One digest. A chain you can verify.

The factory isn't a diagram — it's what the merge builds. One gated pull request stands up a tenant's private image registry, its signing key, a reference build and a running service. Nothing is created outside that merge: provisioning is a consequence of a reviewed change, never a console action.

One reviewed pull request the merge is the authorization created only by the merge Tooling account yours, not ours Private image registry immutable tags · scan on push Signing key in your account signs the digest · no public log Reference build builds · records an SBOM · signs Verify what was just signed unverifiable images cannot promote ✓ promote by digest, not by tag Environment accounts dev → prod dev · test · preprod · prod runs the exact digest that was verified pull scoped to one repository · egress only no inbound rule · no standing credentials Assessment reads upward only evidence out · never a path in reads up, never in
01 · Registry
Immutable by construction

The tenant's own private image registry, created by the merge. A tag can never be repointed — every push is scanned on arrival, and the images already in it keep being rescanned as new findings appear.

evidences RA-5 · CM-5 · SI-2
02 · Build
A real service, tagged once

The reference build compiles a real application with a real dependency tree — that is what makes an inventory and a vulnerability scan say something. Immutability forbids tag reuse, so each build gets its own tag.

evidences CM-5
03 · Inventory
An SBOM bound to the digest

The software bill of materials is generated from the build and attached to the image digest, so it travels with the artifact. A document written afterwards is a different artifact and can't be tied to what actually runs.

evidences SR-4 · CM-8
04 · Signature
Signed where you can verify it

The digest is signed with a key that lives in the tenant's account and never leaves it. Nothing is published to a public transparency log, so the chain holds air-gapped and in government regions, and no build metadata crosses the boundary.

evidences CM-14
05 · Verification
Verification is the control

The build then verifies the signature and the inventory it just produced, over the digest. A failure fails the build, so an unverifiable image never becomes promotable. Signing without verification is ceremony — it proves a key was available, not that the artifact carries a usable signature.

evidences SR-11 · CM-14
06 · Promotion
By digest, never by tag

Every environment runs the digest that was verified — dev, then test, preprod and prod, each behind its own approval. A tag can be repointed, so a tag-pinned deployment can't be verified by content and the gate flags it.

evidences CM-3
We build it. We don't run it.

The pipeline is scaffolded into the tenant's own account, under the tenant's own role — off by default until they ask for it. Nothing of ours ever invokes it, and no deployment opens a path back to us. Assessment reads upward only: evidence leaves the tenant's account on the tenant's terms, and there is no inbound path into a customer environment.

evidences AC-4 · SC-7 · AC-6 · IA-5
Nothing legacy deploys.

Every version in the reference build is chosen against its published end-of-life date — the language runtime, the base operating system and the application framework alike — and anything already sunsetting is rejected before it reaches the image. End-of-life status alone is a critical finding in a modern scanner, with no package vulnerability involved at all.

evidences SI-2 · RA-5

Each step is written to evidence a specific assertion under NIST SP 800-53 Rev 5 — registry and scanning RA-5, CM-5, SI-2 · inventory bound to the digest SR-4, CM-8 · signed and verified image CM-14, SR-11 · promotion by digest through a gated merge CM-3 · tenant and boundary isolation AC-4, SC-7 · no standing credentials AC-6, IA-5.

SET UP & RUN

Stand up the zone, then run it

Stand up a brand-new Control Tower landing zone — Day-0 prerequisites through launch — then vend, manage, migrate and close accounts in it. Every action renders the exact YAML diff, dry-runs first, and opens a reviewed pull request.

  • New landing zone: preflight → cost → launch

DEVSECOPS · DSO

Software factory & platform

Vend a governed tenant, then deploy its private, air-gapped platform — detailed above.

  • Vend tenant — tenant OU + env accounts, one PR
  • Image checks, four scored gates — registry, scan findings, signing, SBOM
  • Deploy platform — private network → cluster → apps
  • Signed, verified images promoted by digest
  • Tenant & fleet views — every tenant read live vs what was declared
  • Air-gapped delivery · Merge & run
ACCESS

Identity, tenant & console access

Map who gets what — and vend the console when it's truly needed.

  • LZA-provisioned roles & groups
  • SCIM group → permission set → accounts
  • Just-in-time, time-boxed console sessions
  • Every session audited — AC-2 / AC-6 / AU-2
CHANGE CONTROL

One policy gate for every change

Every landing-zone change flows through one policy engine — run early on the proposal for instant feedback, and again to enforce at the merge. The cockpit tracks each change from proposed to deployed, with the verdict, an event timeline, and separation-of-duties approvals.

  • Policy-as-code: schema, SCP-immutable, no-regression
  • Report mode (shadow) → enforce when you're ready
  • Break-glass: a governed, audited emergency path
  • Fails closed — no verdict, no merge
PR opened→gate ✓ pass→approve→deploys
ASSURANCE

Drift, readiness, quotas, backup

Prove the zone is what the config says — and see the walls coming.

  • Declared-vs-live drift detection
  • Differential checks — what the app shows vs what the accounts hold
  • Service-limit sentinel (amber/red before you hit a wall)

AI & integrations

An expert sits in the console. Your tracker stays in the loop.

TowerControls drafts the work, explains the failures in plain English, and keeps Jira in sync — and it still never merges without you.

AI · AUTOFILL

Describe your org — it fills the form

Type one sentence about your organization and Amazon Bedrock drafts the whole landing-zone plan into the form: home region, governed regions, Security & Sandbox OUs, Log Archive and Audit accounts, and log-retention windows — tightened automatically when you hint at government or regulated environments. Every field stays editable, and if AI is off it falls back to a sensible starter plan you can still deploy.

AI · ASSISTANT

An assistant on every screen, for everyone

Open the assistant from any screen and ask in plain English — how the console works, how to do a task, or what a finding means and exactly how to remediate it. It's there for everyone on the team, whatever their role, and it knows who you are: ask what you're allowed to see or do — or why a screen looks empty — and it explains your access and points you to what you can reach. Inform-only and scoped to your account, it advises but never acts: it won't change a resource or write code, and an off-topic question gets steered back with good humor. When an Accelerator-Pipeline stage fails, one click runs an AI analysis of the error.

AI · BRIEFING

A 7am briefing in every inbox

Each morning TowerControls emails a rich executive briefing — posture score, grade and day-over-day trend, evidence and control status, open alerts, and account and pipeline health — led by an AI-written overview that opens with the headline, what's good, what changed, and anything glaring. Leadership stays current without opening the console; you set the recipients in seconds.

JIRA · 2-WAY SYNC

Work tracked where your team lives

Connect Jira Cloud or Server/DC and every account vend, migration, or closure can open a tracked ticket — labeled, linked to the work item, and updated as it moves. Flag a ticket for the app to pick up, or approve a change with a Jira label, and the loop closes both ways. Polling-based with no inbound webhook, and it degrades gracefully when it isn't configured.

Security & compliance

Prove it, continuously — against NIST 800-53.

Read live posture from Security Hub, track and remediate the findings, and generate the audit package — POA&Ms, policies and OSCAL — without leaving the console.

You don't implement 800-53 — you implement a baseline of it.

Every framework runs as a program — the obligations no scanner can evidence, tracked beside the live controls.

  • SOC 2, ISO 27001, PCI-DSS, HIPAA, HITRUST, CMMC
  • Attestations with expiry — a lapsed one reopens the gap
  • Crosswalks pinned to the publisher's source version
TOWER STATUS

An AI grade of the whole zone

Bedrock judges the live environment — landing zone, guardrails, shared accounts, FISMA posture — and says what's deployed, compliant, and not.

Two editions

One codebase. Two products.

The same operate, change-control and security plane comes in two editions from a single build — pick the one that matches the compliance you need, not the kind of company you are. Everything in the Commercial edition is in the Government edition; Government adds the government-authorization surface on top — so a commercial SaaS pursuing a federal ATO runs the Government edition too. One runtime parameter chooses the edition — no fork, no separate build.

☁Commercial

Commercial

SOC 2 · ISO 27001 · CIS · PCI · HIPAA · HITRUST · NIST 800-53

Run a secure, governed AWS org and stay continuously audit-ready — framed around the frameworks a commercial auditor actually asks for.

  • Operate the org — accounts, OUs, access, migration, no console
  • Live security posture, scored to CIS AWS Foundations / SOC 2 / ISO 27001
  • Frameworks & coverage — SOC 2, ISO 27001, PCI-DSS, HIPAA, HITRUST, NIST 800-53
  • The change-policy gate, break-glass and full audit trail
  • Compliance Summary report · ISO 27001 / SOC 2 policy drafting
  • Remediation tracking with two-way Jira sync
🛡Government

Government

FedRAMP · NIST 800-53 · FISMA · CMMC · OSCAL

Everything in Commercial, plus the full government-authorization surface — the pieces an ATO actually requires. For federal agencies and commercial vendors selling into them.

＋ Government adds
  • ATO Now — a live gate for every authorization prerequisite, and the full document package once every gate is green
  • FedRAMP scorecard — Low / Moderate / High readiness read off your live posture
  • FedRAMP 20x — the ten Key Security Indicators, the automation-first authorization model
  • OSCAL 1.1.2 — SSP / SAR / POA&M as machine-readable packages
  • FISMA-High migration baseline, and AO / 3PAO language throughout

The Government edition is the superset; a Commercial install simply turns the government-authorization surface off and reframes compliance around commercial frameworks. Both editions are fed by one pipeline, so every feature lands in both at once — they can't drift.

Demonstrated, not described

The claims on this page have been run.

Every figure below was measured in real AWS accounts, not modeled. A promotion was carried out end to end across two accounts, and the environment receiving it checked the signature itself before anything started.

PROMOTION

Proven across two accounts

One environment advanced to a new build while the second deliberately lagged, then took the exact digest the first had proven. Each step was a reviewed merge — the lag and its closing are both on the record.

VERIFIED ON ARRIVAL

The receiver checks, not the sender

The receiving account re-verified the signature and the bill of materials against the tenant's own key, from inside its own account, before the workload changed. It never accepts a build on trust.

MEASURED

Zero ways in

Both environments: no internet gateway, no address translation gateway, no public address, no default route. Counted in the live accounts, not asserted in a diagram.

471 TESTS

Every build, or it doesn't deploy

471 tests across 41 files run on each build and block the deploy on failure — including tests that assert the isolation above and refuse a deployment that could reach the internet.

59 CHECKS

Rehearsed before it runs

Before a change is merged, 59 checks rehearse it — including a real change set in every target account, so the platform states what it would build before it builds anything.

SELF-CONTAINED

Nothing phones home

Signing and verification never contact a public transparency service, and images are fetched over private endpoints. The whole chain works in a disconnected region.

Safe & compliant by construction

Built to be trusted.

The safety is in the machine, but the human owns the merge — TowerControls writes to a feature branch and stops; nothing reaches AWS without a pull request a person reviewed. Everything below holds by default.

HUMAN-GATED

You own the merge

The app proposes to a branch and stops. Your merge to main is the only release gesture — no change reaches AWS without it.

IN YOUR ACCOUNT

Single-tenant by design

Deploys into your own AWS account from one pre-filled, one-click launch link. Single-tenant and serverless — your environment data never leaves it.

BASELINE

FISMA-High / CIS

SCPs, Config, Security Hub, GuardDuty, EBS & S3 controls applied on enroll — edition-aware.

EVIDENCE

Full audit trail

Every apply recorded, with snapshots and one-click revert.

LEAST PRIV

Read-scoped access

Cross-account reads via a single least-privilege role; writes gated off by default.

SUPPORT

Support on your terms

Support sees a health heartbeat — never your data — and can change an install only inside a time-boxed window you grant. Closing the window ends every session it issued.
