Subscription Tiers · Layer 03 · Operate

Compliance for the system you already run.

Sentinel doesn't replace your billing software, your ERP, or whatever stack you've spent years getting your team trained on. It adds the compliance layer on top of it. AWIA, EPA SDWA §1433, CISA OT, CIRCIA, and every active state mandate — tracked, evidenced, and certifiable from the system you already use every day.

Why this matters: Most utilities aren't ready to swap out the platform that runs their billing, work orders, or operations. They need compliance that meets them where they are. Sentinel does that — runs alongside your current systems, owns the regulatory layer, and gets you compliant in a weekend without disrupting anything else.

Integration · Available inside Radeus

Sentinel comes built into Radeus at preferred pricing.

If your utility runs on Radeus Pro or Radeus Enterprise, the Sentinel compliance module is available as an integrated add-on — same engine, same regulatory coverage, sold inside the Radeus subscription at a tier-matched rate. Compliance lives where your billing and operations already do, not in a separate tab.

Pick the tier that matches your scale.

Every tier includes the regulatory engine. The difference is how many users, how much advisor time, and which higher-tier modules — multi-plant dashboards, audit support, governance reporting — you need.

Subscription questions, answered.

Most utilities don't run a single software stack — they run several, accumulated over years. Sentinel is built for that reality. Here's how it fits.

Do I have to switch off my current ERP or billing software?
No. Sentinel is purpose-built to run alongside whatever you already use — Tyler, Munis, Caselle, BS&A, Springbrook, custom-built, spreadsheets, all of it. Sentinel owns the compliance layer; your existing systems keep doing what they do. Most customers connect Sentinel to their utility data via simple CSV upload or read-only API connection.
How do I know which tier I qualify for?
Service connections is the primary metric — it's how state regulators (notably NY PSC Part 1200) draw the line. Population served is the alternate identifier and matches AWIA's tier structure. If your utility falls in a gray zone or has multiple service areas, pick the higher tier or contact us — we'd rather under-quote than have you pay for capacity you don't need.
What if my utility grows past my current tier?
You upgrade — month-to-month, prorated, no penalty, no contract restart. We don't lock customers into multi-year commitments to capture growth. If you cross 1,200 connections or 3,300 population from Lite to standard, we'll flag it in your dashboard and let you decide when to step up.
Is there a contract or can I cancel?
Month-to-month subscription. Cancel any time, takes effect at the end of your current billing period. No early termination fee. The only caveat: deliverables you've generated stay yours, but live access to AXIOM and the dashboard ends at cancellation. Export your audit packet and evidence files before you cancel — we make that one click.
Does Sentinel cover wastewater, or just drinking water?
Drinking water is the core. Wastewater coverage exists for combined utilities (drinking + wastewater under one PWS) on the standard tier and above — including NY DEC 6 NYCRR 616/650/750 reporting. Wastewater-only utilities aren't our primary fit today; we're focused on the drinking-water-cyber gap. If wastewater is your only operation, talk to us before subscribing.
How does this compare to hiring a consultant?
A typical mid-tier utility pays consultants $15K–$60K for a single AWIA RRA + ERP cycle, then $10K–$40K/year for ongoing maintenance. Sentinel runs $18,000/year on the standard tier — and produces evidence the consultant can't, because the artifacts live in your system, not theirs.
What about the one-time products (Layer 01, Layer 02, AWIA Bundle)?
Different products, different jobs. The Risk Snapshot ($250) tells you where you stand. The Implementation Plan ($1,995) gives you the roadmap. The AWIA Bundle ($3,500–$10,000) handles the recertification for you. The subscription is for ongoing operation — the system that keeps you compliant cycle after cycle. Most customers buy Layer 01 first, then either subscribe immediately or run Layer 02 + the bundle, then subscribe.

The deadline is June 30, 2026.
The system you already run can be ready.

Pick a tier, subscribe, and connect Sentinel to your existing stack. No platform swap, no consultant engagement, no six-week implementation. Compliance starts the same day your subscription does.
