Trust Center Compliance Program

Trust Center + Compliance Program (self-hosted Probo)

Give a company a credible security posture quickly: a branded public trust center plus the program behind it — frameworks, controls, policies, a risk register, inventories, a vendor/sub-processor list, and a DPA that are internally consistent. Built on Probo (open-source compliance/trust platform), self-hosted, so there is no per-seat SaaS bill.

This produces the artifacts and public page, not an audit. An actual SOC 2 / ISO 27001 attestation still requires an independent auditor; this gets the company audit-ready and publicly credible.

When to use

• A startup/SaaS needs to show security maturity to customers/partners now.
• You want the underlying program (controls, policies, risk register, RoPA, sub-processors, DPA) authored coherently, not as disconnected templates.
• Self-hosting is preferred over Vanta/Drata/SafeBase pricing.

When NOT to use

• The company needs a signed attestation → engage an auditor (this is prerequisite work, not a substitute).
• A fully managed platform is genuinely wanted and budget exists.

Part 1 — Deploy + brand Probo

Probo runs as containers behind a reverse proxy on a small box (see [[ec2-instance-connect-data-pull]] for keyless prod shell access).

1. Deploy the Probo stack via its docker-compose; put it behind nginx on a dedicated subdomain (e.g. trust.<domain>).
2. TLS — issue/renew the cert via ACME. If issuance breaks, check the ACME http-01 path routing through nginx before blaming the CA.
3. Branding without forking the app: use nginx sub_filter to rewrite the served HTML (product name, logo) at the proxy. Enable it on the right Content-Type and disable gzip on those responses so sub_filter can match.
4. Backups + secrets: confirm DB backups run and the app's secret/vault store is populated before authoring — losing the program later is worse than a slow start.

Gotchas that will bite

• PDF export dumps raw JSON if ProseMirror rich-text (esp. table cells) lacks required node attributes. When authoring policies via the API/DB, produce well-formed ProseMirror (valid attrs on table/cell nodes) or exported PDFs show raw document JSON instead of formatted text.
• Dark mode breaks branding: light-lock the theme (pin the theme CSS variables to light values) unless dark is fully styled, or the trust center renders half-branded for dark-mode visitors.
• Custom domain / www: set the website's canonical/host field to the exact public host (with/without www) so links and canonical URLs resolve.

Verify the public trust center renders correctly (light + dark, mobile) with [[cdp-render-verification]].

Part 2 — Author the program (coherent, not templated)

Build it so controls ⇄ policies ⇄ measures line up. Order that works:

1. Frameworks + controls — enable SOC 2, ISO 27001, and GDPR; import their control sets in Probo.
2. Core policy set — author the standard policies (Information Security, Access Control, Acceptable Use, Data Protection/Privacy, Incident Response, Business Continuity, Vendor/Third-Party, Change Management, Data Retention, Encryption/Key Management, etc.). Write them specific to the company (its real stack and data flows), not generic boilerplate — strip any "template" notices.
3. Risk register + inventories — a risk register, plus asset, data, and RoPA (GDPR Records of Processing Activities) inventories, plus a vendor / sub-processor list. Ground each in the company's actual providers.
4. Map it together — link controls → the policies that satisfy them → the measures/evidence. Unmapped controls are the tell of a fake program.
5. Public content — publish frameworks, policy summaries, a DPA, the sub-processor list, and an Updates timeline so the trust center reads as a living program, not a snapshot. Consolidate contact to a single address (e.g. legal@ / security@).

Writing quality

Policies and privacy content are read by real prospects and lawyers — apply [[beautiful-prose]] / [[humanizer]]: plain, specific, no filler, no invented certifications or dates. Cite the framework clause where relevant. Never claim an attestation the company does not hold.

Deliverables checklist

• Public trust center live on trust.<domain> (TLS valid, branded, light+dark, mobile-verified)
• SOC 2 / ISO 27001 / GDPR frameworks + controls loaded
• Core policy set authored (company-specific, no template notices)
• Risk register + asset/data/RoPA inventories + vendor/sub-processor list
• Controls mapped to policies + measures (no orphan controls)
• Public DPA + sub-processor list + Updates timeline published
• Single canonical contact address
