For Enterprise IT

# One org-wide policy for every team

Deploy once on managed SaaS, in your VPC or air-gapped. Rules are scoped by repository; for several business units, we scope the rollout with you.

Rollout for shared services

## Org-wide governance in three steps

1.  01
    
    Stand up one instance
    
    Managed SaaS, your cloud or air-gapped. Same binary, same API.
    
2.  02
    
    Publish the policy centrally
    
    One org-wide policy for vulnerabilities, licenses, provenance and supply-chain signals.
    
3.  03
    
    Scope rules by repository
    
    Target a rule at specific repositories. Exceptions carry an expiry and optional two-person approval.
    

Availability

## HA without a platform team

Two replicas behind a health check, and fail-over is automatic.

Part

Behaviour

Proxy

Stateless. Any Kubernetes, ECS or Nomad scheduler; no sticky sessions.

Control plane

Your managed database: RDS, Cloud SQL or self-managed.

Cache

Local disk for dev, S3-compatible blob store for prod.

Degraded data

Fails open with an audit row by default. CHAINSAW\_COVERAGE\_MODE=closed refuses anything not fully checked against your mandatory sources.

Upstream outage

Served from cache.

Metrics

50+ Prometheus counters. OpenTelemetry tracing is opt-in.

Identity

SAML 2.0, OIDC and SCIM 2.0 on Team and Enterprise. Admin, manager and viewer roles with fine-grained API scopes. [Supported IdPs](https://chain305.com/integrations/)

Hardening levels

## Four levels, one rollout path

Each level is additive: same proxy, same policy, more tooling around it. [Each level in detail →](https://chain305.com/product/enterprise-rollout/)

Effect

L1

Monitor only

How Chainsaw fits

Artifactory / Nexus

Keep them. Chainsaw fronts the public registries they proxy. Zero dual-publish.

Cloudsmith / JFrog SaaS

Point Chainsaw's upstream at it; your URLs stay.

Verdaccio / npm mirror

The mirror stays; Chainsaw replaces the public hop. No .npmrc change.

Snyk / SCA scanners

Run both. Chainsaw decides what enters; SCA reports what is there.

## Long form

The full text behind this page, including detail the page itself leaves out.

For Enterprise IT

### One org-wide policy for every team

Deploy once — managed SaaS, your own VPC, or fully air-gapped. One org-wide policy set, with rules scoped by repository and exceptions that carry an expiry and optional two-person approval. For estates with several business units, we scope the rollout with you.

The pain

-   Dependency policy lives with individual teams — no central rollout path.
-   Tooling requires either a cloud footprint or a heavy on-prem install with no path between them.
-   Every new control adds latency to developer workflows.
-   Air-gapped networks need a story that isn't "rebuild from scratch every release".
-   A public attack like Shai-Hulud lands — or a security questionnaire does — and there's no install-time control to point to.

What changes

##### Central rollout, local enforcement

Deploy once; teams inherit the baseline with room for local additions. Governance without flattening.

##### Managed, cloud, or air-gapped

Managed SaaS, your own Kubernetes or Docker, or fully air-gapped. Same binary, same API, same policy format.

##### Cache-backed performance

Repeat installs answer from cache. Rollout doesn't become a new helpdesk ticket queue.

Availability

#### HA topology that doesn't need a platform team

Chainsaw's proxy tier is stateless. Scale it horizontally behind any load balancer. The management plane runs on a managed relational database with an optional Redis or NATS queue for webhook delivery at scale. Stand up two replicas, put a health check in front, and fail-over is automatic.

-   **Stateless proxy:** any Kubernetes, ECS, or Nomad scheduler works. No sticky sessions.
-   **Managed-database control plane:** bring your own RDS, Cloud SQL, or self-managed instance.
-   **Blob-store cache:** local disk for dev, S3-compatible for prod. Purge and re-populate without downtime.
-   **Fail-open or fail-closed:** a deployment-level setting, fail-open by default. CHAINSAW\_COVERAGE\_MODE=closed makes Chainsaw refuse any package it could not fully evaluate against the data sources you declare mandatory; left unset, a degraded source fails open with an audit row. Upstream-registry outages are served from cache.
-   **Prometheus metrics:** 50+ counters out of the box. OpenTelemetry tracing is opt-in.

Identity

#### SSO, SCIM, and RBAC without custom code

SAML 2.0, OIDC, and SCIM 2.0 ship on Team and Enterprise. Any compliant IdP works; these are the ones we see most often. RBAC has admin, manager, and viewer roles with fine-grained API scopes, and SCIM drives provisioning and deprovisioning automatically.

**Okta** SAML 2.0 · OIDC · SCIM 2.0

**Microsoft Entra (Azure AD)** SAML 2.0 · OIDC · SCIM 2.0

**Google Workspace** OIDC · SCIM 2.0

**Auth0** OIDC

**Keycloak** OIDC

**Generic SAML 2.0 / OIDC** Any compliant IdP

Air-gapped

#### Disconnected from the public internet, end to end

Chainsaw runs fully air-gapped [on Enterprise](https://chain305.com/pricing/). The server URL can be baked into the CLI at build time, so your engineers never see a public origin. Sync the malware index, the typosquat seed lists, and the CVE database into your environment on whatever cadence you want; Chainsaw reads them from the local filesystem.

`CHAINSAW_WEB_UI_URL`, `FORCE_HTTPS`, and `NEXT_APP_BASEPATH` let the dashboard live on a subpath of your internal domain. Cross-platform binaries ship for macOS, Linux, and Windows, each with a published SHA-256 checksum for download verification.

Migration

#### Front your existing registry — don't rip it out

Most teams already run something: Artifactory for internal artifacts, Cloudsmith for a subset of public packages, a Verdaccio mirror, or an SCA tool doing post-install reporting. Chainsaw [slots in front](https://chain305.com/product/how-it-works/) of whichever you have.

-   **Artifactory / Nexus** Keep them. Chainsaw sits in front of the public registries they proxy. Internal artifacts keep resolving out of Artifactory; public installs route through Chainsaw's policy. Zero dual-publish.
-   **Cloudsmith / JFrog SaaS** Point Chainsaw's upstream at the Cloudsmith registry. Your team keeps using Cloudsmith URLs; Chainsaw enforces policy on every fetch.
-   **Verdaccio / internal npm mirror** Chainsaw replaces the public-upstream hop and keeps the mirror in place. No change to the developer's .npmrc.
-   **Snyk / SCA scanners** Run both. Chainsaw decides what can enter; your SCA tool reports on what's already there. They target different stages.

Hardening levels

#### Four levels of enforcement, one rollout path

Most teams start at Level 1 (monitor) and stop at Level 2. Regulated environments push to Level 3 or 4. Each level is additive — same proxy, same policy, more tooling around it. On Team and Enterprise, the /onboarding/hardening wizard generates the manifests, firewall snippets, and MDM payloads ready to apply.

1.  L1
    
    ### Monitor only
    
    Audit every install. Block nothing.
    
    The proxy logs every package decision with a structured row. Rules ship in monitor mode by default; the daily report tells you which installs would have failed. Zero developer disruption — every CI job, every laptop install passes through the audit log.
    
     Tooling: proxy + dashboard.
    
2.  L2
    
    ### \+ Admission webhook
    
    Cluster-side enforcement on Kubernetes.
    
    Add a Kubernetes ValidatingAdmissionWebhook so workloads pulling images outside policy are rejected at apply-time. Closes the 'CI sneak-around via direct kubectl apply' gap that monitor mode can't see. Helm chart and Kustomize overlay shipped with the runbook.
    
     Tooling: + K8s admission controller.
    
3.  L3
    
    ### \+ Network egress allowlist
    
    Block direct registry access at the network edge.
    
    Push a firewall / egress-policy snippet that allowlists Chainsaw's proxy and denies direct egress to npmjs.org, pypi.org, registry-1.docker.io, etc. Now the proxy is the only path — no developer can fall back to the public registry by editing one line of .npmrc.
    
     Tooling: + network egress policy.
    
4.  L4
    
    ### \+ MDM payloads on managed laptops
    
    Lock the developer machine.
    
    Distribute MDM (Jamf, Intune, Workspace ONE) payloads that pin the package-manager registry config, prevent override, and bake the proxy URL into the laptop image. Air-gapped variant available for regulated environments. The CLI ships with a baked server URL so engineers never see a public origin.
    
     Tooling: + MDM profile + checksum-verified CLI build (SHA-256).
    

Rollout for shared services

#### Org-wide governance in three steps

1.  ### Stand up one Chainsaw instance
    
    Managed SaaS, self-hosted on your cloud (Docker or Kubernetes), or fully air-gapped. Same binary, same config surface, same API.
    
2.  ### Publish the policy centrally
    
    Define one org-wide policy for vulnerabilities, licenses, provenance, and supply-chain signals.
    
3.  ### Scope rules by repository
    
    Target a rule at specific repositories. Exceptions carry an expiry and optional two-person approval.
