How we prove every number, protect every resident, and keep THG honest.
Sentinel is the always-on system that runs underneath everything Triad Holdings Group does. It watches, verifies, redacts, and reports — so that city officials, auditors, journalists, and investors can trust what we say without having to take our word for it.
What Sentinel actually is
Think of Sentinel as a tireless head of security, head of compliance, head of data, and internal auditor — all running 24/7, all in one system.
Most organizations need five separate teams to do what Sentinel does on its own: a Security Operations team to catch threats, a Compliance team to mask private resident data, a Data Quality team to make sure every number is reproducible, a Fraud/Integrity team to flag tampering, and an Audit team to package proof for outsiders. Because THG is new — we officially opened in April 2026 — we built Sentinel from day one so we could operate at the standard of a much larger institution while staying small, fast, and honest.
The five jobs Sentinel does, every minute of every day
Watches every login, every API call, and every page load for suspicious activity. If something looks like an attack or a stolen account, Sentinel can lock the door before damage happens.
No staff member — including admins — ever sees a full name, address, account number, or phone number in normal use. Sentinel automatically masks PII (showing 'J. D.***' instead of a full name) so privacy is enforced by the system, not by trust.
Every economic figure THG publishes can be traced back through the exact data sources, cleansing steps, and formulas used. Each report is sealed with a cryptographic hash so anyone can confirm it hasn't been altered after the fact.
Sentinel monitors public social sentiment, news, and incident alerts across Danville and correlates them with foot traffic and spending in nearby zones — so we can show real cause-and-effect, not guesses.
If a number changes without a logged reason, if a file is touched outside normal hours, or if two data sources disagree, Sentinel raises a flag and pauses the affected report until a human reviews it.
When Sentinel detects a broken integration or a degraded service, it can apply a documented repair and log exactly what it did, so nothing is fixed quietly in the dark.
How smart is it, and how accurate?
We hold ourselves to a simple rule we call "truth before scale": we would rather publish fewer numbers slowly and correctly than impressive numbers quickly and sloppily. Sentinel is the system that enforces that rule when no one is watching.
How Sentinel ties into the rest of THG
Sentinel isn't a page — it's the layer every other page sits on top of.
What's new: the Intelligence Engine
The latest module makes Sentinel's work visible to outsiders for the first time.
Until now, everything Sentinel did happened behind the scenes. The new THG Audit, Verification & Sentiment Intelligence Engine is a dedicated console where a city auditor or council member can:
- Ask plain-English questions like "How much local tax was generated in zone 24541 last month?" and see the answer, the formula, and the data sources side by side.
- Open the Verification Ledger — every transaction with masked source IDs, the exact tax math (Danville's 5.3% sales + 1% meals), and an audit status on every row.
- Watch the Sentiment Monitor overlay community incidents against local spending patterns, so policy decisions can be tied to real economic impact.
- Generate a signed executive brief (Deficit Remediation, Missing Middle, Opportunity Zone Audit) as a PDF with a verification hash printed on the last page.
Every download from the Intelligence Engine carries a cryptographic fingerprint. Anyone who receives a THG report can paste that fingerprint back into the portal and confirm, in one click, that the document hasn't been edited.
Why we built it this way
THG is eight weeks old. We know that earning the trust of Danville, its leaders, and its residents isn't something we can claim — it has to be something anyone can check. Sentinel is how we make checking easy. It's also how we promise to grow responsibly: as we add more neighborhoods, more vendors, and more municipal partners, the same verification, the same masking, and the same audit trail will apply to every single new record.
If a council member, journalist, or resident ever wants to see the math behind a number we published, the answer is always the same: open the Intelligence Engine, run the query, download the proof.
Auditors and city staff can request portal access for live verification.
