Trust & Data Integrity

Audience: enterprise IT, security, legal/compliance, and procurement reviewers — including public-sector and higher-education buyers. See Education specifics below for FERPA and accessibility detail.

A note on the name. "SOCIII" (pronounced "so-chee") is our product name. It is not a reference to SOC audit frameworks (SOC 1/2/3). SOC 2 attestation is on our roadmap (§8); until then, please read "SOCIII" as a product name, not a compliance claim.

One line: *SOCIII is a tamper-evident audit trail that your governed AI workers write to. The record is the product; the workers are the interface.*

---

1. The mental model

Underneath the AI workers is an append-only system of record: every action is written as an immutable event, hash-chained, periodically anchored to an independent ledger, and attributable. The AI proposes; the rules engine validates; events append. Nothing is silently overwritten.

Two layers, governed independently:

1. The record — append-only, tamper-evident event store. The durable asset your auditors care about.

2. The workers — AI agents that read context and propose actions, never bypassing the rules engine.

The right frame for a large institution: *a governed audit trail with an AI interface*, not "AI agents loose in our data."

2. Data residency — where it lives, who controls it

· Tier · What it is · Isolation · Keys ·

· ------ · ----------- · ----------- · ------ ·

· Shared (standard) · Logical multi-tenant; every record scoped to your tenant ID · Logical · Platform-managed ·

· Dedicated · Your own isolated project/database, region-pinned · Physical (separate project) · Customer-managed (CMEK) — you hold keys in your KMS, can revoke ·

· Customer-hosted (BYOC) · Deployed into *your* cloud tenancy via infrastructure-as-code · Full — runs in your account · Yours ·

For most institutions, Dedicated + CMEK + DPA clears the security review without the burden of self-hosting.

BYOC — set expectations honestly. BYOC is maximum control *and* maximum responsibility: you take on patching, scaling, monitoring, and uptime of the deployment in your own cloud. It is the right choice for sovereignty mandates, but it is not "more control for free" — it is an operational commitment on your side, with a shared-responsibility matrix we provide before you choose it.

3. Data integrity — and the precise claim

We make two distinct guarantees; conflating them is a mistake, so we separate them:

1. Tamper-evidence within the store (hash-chaining). Records are chained by hash. Any alteration breaks the chain and is *detectable*. On its own this detects tampering after the fact; it does not, by itself, stop an actor with deep infrastructure access from rewriting history *and* recomputing the chain.

2. Tamper-resistance against that actor (independent anchoring). Periodically we publish a Merkle root of the record set to an independent, append-only register outside our control. Because the external anchor is not ours to rewrite, an inside-infrastructure actor *cannot* silently rewrite history and re-anchor — the divergence is provable. This is the guarantee that actually holds, and it is the one to lean on.

The honest bound — the anchor interval. Anchoring is periodic, so the insider-resistance in (2) protects everything *up to the last anchor*. Records created since the last anchor are protected only by the weaker hash-chaining in (1) until the next anchor publishes. Our current anchor cycle runs at minimum daily; the exact frequency is disclosed in the service documentation and updated as our infrastructure evolves.

Which anchor gives which property — no sleight of hand. These are different trust models and we don't blur them:

Our current production default is RFC-3161 trusted timestamping via an independent TSA, with Merkle-tree inclusion proofs published to an append-only transparency log. Public-chain anchoring is available as a configuration option on Dedicated tier. The insider-resistance argument holds in its strongest form under public-chain anchoring; under a TSA it reduces to "a trusted third party attests the timeline."

Verify it yourself — current state, stated plainly. Today the record is independently verifiable against a published proof: we publish the inclusion proof and the external anchor reference, and your team (or an auditor) can confirm a record against the public anchor by hand. A standalone one-command verifier (CLI/API) is on the roadmap — until it ships we do not claim a turnkey "click to verify" tool; we claim verifiability against a published proof, which is the property that actually matters for an audit.

Immutability ≠ cryptocurrency. You hold no token, run no wallet, and take on no treasury/accounting exposure. Anchoring targets, in order of how easily they clear an institutional audit:

1. No-crypto (default for regulated buyers): RFC-3161 trusted timestamping + a public transparency log. Cryptographic proof, zero crypto exposure. This is our default; we do not foreground a blockchain unless you ask.

2. Public-chain anchoring with platform-sponsored fees: the "anchored to a public ledger" story, you never touch a token, any cost is a metered platform fee.

3. Customer-operated anchor: available only if you require it; the only path that would put crypto operations on your side — we steer institutions away from it.

5. Identity & attribution

Every event records who/what initiated it, under which capability, at what time. Attribution is only as strong as the identity layer beneath it:

We state the basis explicitly per tier rather than implying directory-grade attribution everywhere.

---

6. Internal access controls (insider threat)

---

7. Retention, deletion & the anchor tension

- Dedicated / BYOC (CMEK): "right to be forgotten" uses crypto-shredding — destroying the per-tenant CMEK key renders the encrypted data permanently unrecoverable while the residual anchor remains a meaningless hash.

- Shared / Standard (platform-managed keys): crypto-shredding is not available per-record on this tier, so hard-delete is performed by purging the plaintext record from primary stores and backups within the cascade window above, leaving only the non-reversible anchor leaf. For institutions with strict expungement requirements (e.g., FERPA record correction/deletion), we recommend the Dedicated tier, where deletion is cryptographically provable.

8. Security posture, incident response & disclosure

---

9. Subprocessors

A current subprocessor list is part of the DPA. At minimum it discloses, for each: name, role, region, and what data category it touches. Model vendors your workers call (e.g., Anthropic/Claude, OpenAI/GPT) are subprocessors and are listed as such with their data-handling terms.

Model training — the precise claim. No model vendor we use trains on your data. This is the consistent, contractual guarantee across every model subprocessor: we operate under enterprise API terms that prohibit training on inputs/outputs, and we will not route your data to any tier that permits it.

The thing that varies per vendor — and is disclosed exactly in the subprocessor exhibit — is transient retention (how long, if at all, a prompt is held for abuse-monitoring before deletion). Some vendors offer zero-retention; others hold for a short, bounded window. "No training" is the headline and it holds everywhere; "retention window" is the per-vendor detail, listed in the exhibit so the two are never conflated.

10. Onboarding a large institution

Two tracks, both delivered through SOCIII:

1. Governance setup (with your IT/security): guided selection of tier, region, CMEK, DPA, SSO, and the export/exit plan → a documented governance configuration for your institution.

2. Enablement: your team learns to build and govern their own workers on the SDK — so one engagement expands across departments without bespoke vendor work. You own the build; we provide the substrate and rails.

Shared responsibility — who guarantees what. SOCIII guarantees the substrate: the append-only record, the rules engine, the approval gates, anchoring, and isolation. When *your* team authors workers and rules on the SDK, the correctness of those workers and rules is yours — a misconfigured customer-built worker is the customer's exposure, exactly as a misconfigured query against any platform would be. The engine still enforces capability declarations and approval gates underneath every worker, customer-built or not.

On maturity, honestly: this governance + enablement path is how we run every institutional engagement. For a first university-wide commitment we typically recommend a scoped departmental deployment that expands, which is both lower-risk for you and a more credible footing than "bet the institution on an early-stage vendor."

11. Honest maturity statement

We are an early-stage enterprise vendor with production infrastructure and an honest roadmap — not a pilot program, and not a decade-old platform.

13. Talking points (short version)

14. Education-sector specifics

This section exists because a public university's review surface is not the generic enterprise one.

FERPA. Where SOCIII processes student education records, we act as a "school official" with a "legitimate educational interest" under 34 CFR §99.31(a)(1) — meaning we use education records only under your direction, only to perform the service you've contracted, and we do not re-disclose them except as you authorize. Our subprocessors (including model vendors, §9) operate under the same direct-control and no-training terms. A FERPA addendum / DPA captures the school-official designation, direct-control language, the audit-and-evaluation provisions, and subprocessor re-disclosure handling. The FERPA addendum is available on request and executed as part of the standard DPA for education customers.

Data classification & minimization. We support — and recommend — sending the minimum necessary category for each workflow, and we document what data classes are appropriate for each tier. Highly sensitive categories (disciplinary, disability/accommodation, health) belong on Dedicated + CMEK, where deletion is cryptographically provable (§7).

Accessibility — Section 508 / WCAG / ADA. We commit to WCAG 2.1 AA as the conformance target and will provide a VPAT. A VPAT is currently in preparation; contact us for the current conformance gap disclosure and remediation timeline.

Customer audit rights. Pending SOC 2 (§8), the MSA grants you a right to audit on cause plus an annual security questionnaire; once SOC 2 is available, the report satisfies the standing audit right with audit-on-cause preserved.

Data residency for AI calls. Beyond storage region (§2), prompts that may contain student PII are processed in US East (us-east1) by model subprocessors; the per-vendor processing region is named in the subprocessor exhibit (§9).

Pricing — plain language. Education tier: $99/month base + $5 per active student per month (first 5 students included). Students use their existing institutional Google or email account — no separate credential purchase, no single-vendor email lock-in. Above 1,000 active students, we switch to a flat site license — contact us. A standard DPA + FERPA addendum are included at no extra charge. This is the same pricing and agreement we offer every education customer; there is no secret enterprise negotiation track.
