Zero Outbound Network

Air-gapped GRC for CUI environments with no internet egress

For the contract that prohibits all outbound network calls. Same platform, deployed inside your isolated boundary.

Some DoD contracts prohibit any tooling that makes outbound network calls: license checks, telemetry, auto-updates, error reporting, even DNS lookups outside the boundary. Most GRC platforms can't deploy in that posture. Readyline ships an air-gapped variant with zero outbound dependencies: no phone-home, no auto-update, no license server check. Updates arrive as signed artifact bundles you stage manually inside your boundary. Audit logging goes to your SIEM, not ours.

Why most GRC platforms can't deploy air-gapped

Three hidden dependencies that disqualify a "self-hosted" platform from a true air-gap.

Phone-home license check

Many "self-hosted" platforms periodically validate the license against a vendor server. That outbound call disqualifies the deployment from air-gapped environments. Contract violation, even if the call is benign.

Auto-update mechanism

Most self-hosted platforms pull updates from the vendor's CDN. Air-gapped boundaries block CDN access. The platform either breaks (no updates) or violates contract (outbound calls).

Error reporting / telemetry

Sentry, Bugsnag, vendor analytics, all common in self-hosted platforms, all blocked by air-gap firewalls. The platform throws errors trying to report errors. Operationally hostile.

How the Readyline air-gapped variant works

Six design choices that make true air-gap feasible.

Zero outbound by default

No license check, no telemetry, no error reporting to vendor, no auto-update poll. Verifiable with egress firewall logs: zero packets leave your boundary attributable to Readyline.

Signed update bundles

When you want to update: download the signed bundle on a connected machine, transfer via approved media, verify signature, stage in dev tenant, promote to prod. Your process, your timing.

Offline license model

License is a signed file you receive at contract signing. Validated locally at startup against an embedded public key. No outbound check.

Your MySQL, your backups

Standard MySQL 8.0 backend. Your DBA owns the backup schedule, the restore drills, the replication topology. We document patterns; you implement.

Logs to your SIEM only

Audit events emit to syslog / JSON file. Your SIEM (Splunk, Sentinel, Elastic, etc.) ingests them. Nothing flows to a vendor-hosted log aggregator.

Your IdP, your auth

SAML / OIDC integration with your existing identity provider (AD FS, Okta on-prem, Keycloak). Per-role access controls. No vendor-side user accounts.

FAQ

Air-gapped GRC questions

What contracting officers and security architects ask before approval.

Yes. Run it in a network namespace with no egress route and watch your firewall logs. We provide a published list of zero-egress expectations; you confirm it with your network team during the proof of concept.

Same signed-bundle process as feature updates. We publish security bulletins via your existing vendor communications channel (email, phone, encrypted file transfer). You decide cadence: monthly, quarterly, or only-when-CVE. We commit to publishing security-relevant patches within a defined SLA in the contract.

Lose: AI policy drafting (which requires outbound calls to the Anthropic Claude API by design). Gain: data sovereignty, zero outbound, contract compliance for environments where SaaS GRC is out of scope. For environments that need AI features and air-gap, we're scoping a future air-gapped LLM hosting model, out of scope today.

Scoped per contract. A typical air-gapped deployment runs in phases: (1) infrastructure prep with your team, (2) initial install + smoke test in dev, (3) configuration aligned to your CMMC scope, (4) UAT, (5) production cutover. We provide the runbooks; you execute on your timeline.

Yes, on request. We can provide an SBOM in CycloneDX format for a given release, which your vulnerability management team can ingest into your SBOM tool of choice. Ask for it during deployment scoping.
