A side-by-side read for procurement evaluators shortlisting safety monitoring software vs SCADA in the same evaluation cycle. The matrix below names five gaps raw IoT and generic SCADA tools leave open — EHS compliance reporting, audit-trail integrity, permit-to-work workflows, incident alerting, and role-based access — and what Pactwell's always-on correlator changes about each one.
Positioning
Generic sensor dashboards, standalone SCADA tools, and a purpose-built EHS IoT platform were built for different problems. The cards below name what each one is actually doing — so the shortlist reads against claims a reviewer can verify.
Generic sensor dashboards
Sensor readings stream into a dashboard; thresholds fire alerts. There is no compliance mapping to named OSHA/EPA citations, no permit awareness, and no tamper-evident evidence pack at the moment of the breach. The person who reads the alert decides what it means and what to file.
Standalone SCADA tools
SCADA was designed to control industrial processes — not to file OSHA-ready reports. There are no OSHA-ready report outputs, no tamper-evident log, and the permit registry lives in a separate paper system the SCADA data never sees.
EHS IoT platform
Always-on correlator across sensor + permit + CCTV, reasons before it files, ships a tamper-evident evidence pack at the moment of the breach, maps each alert to the relevant EHS rule, and scopes every view by role — the same loop enterprise buyers ask for in the FAQ.
What changes
The four cards below pair the raw IoT or SCADA status-quo with the Pactwell surface that closes the gap. Each card is written against a concrete procurement question, not a feature-by-feature spec sheet.
With generic IoT / SCADA
Raw sensor data with no EHS rules layer — a threshold breach fires a number, not an incident. There is no classification, no regulatory reference, and no permit awareness attached to the alert.
With Pactwell
The correlator reasons sensor + permit + CCTV through EHS rules; the alert arrives as a classified incident with regulatory context already attached — not a number someone must manually triage.
With generic IoT / SCADA
No OSHA-ready output — compliance reports are assembled by hand from sensor exports after the fact. The person who assembles the report decides what the cells say.
With Pactwell
Audit-ready PDF written at the breach moment, cross-referencing sensor reading, CCTV frame, and permit state — the PDF the auditor opens is the PDF the platform wrote, not a hand-compiled reconstruction.
With generic IoT / SCADA
Raw IoT logs are mutable; a corrected reading overwrites the prior value with no co-signed record. Whoever holds database access can back-date a threshold breach or remove a sensor event.
With Pactwell
Append-only evidence pack, co-signed at the moment of the alert — the breach record cannot be back-dated by whoever holds database access. The log is the log.
With generic IoT / SCADA
SCADA has no permit-to-work registry; hot-work and confined-space permits live in a separate paper system the sensor data never sees. A permit-vs-atmosphere mismatch goes undetected until someone walks the bay.
With Pactwell
Native permit registry correlated in real time against sensor readings — a permit-vs-atmosphere mismatch fires the correlator before the supervisor walks off the bay. Sensor data and permit state share the same record.
Side-by-side
The matrix below mirrors the seven procurement questions enterprise buyers ask when sizing an EHS IoT platform against generic tools — EHS compliance reporting, audit-trail integrity, permit-to-work workflows, incident alerting, role-based access, OSHA-ready reports, and cross-signal correlation. Every Pactwell column maps to a shipped surface.
| Feature | Generic IoT / SCADA | Pactwell |
|---|---|---|
| EHS compliance reportingWhether the platform maps sensor events to named OSHA/EPA citations or leaves compliance mapping to a separate team after export. | No mapping to named OSHA/EPA citations. Sensor thresholds fire numbers; a separate team maps them to regulatory standards after the fact. | Cross-signal correlator classifies each breach against the relevant EHS rule at the moment of the alert. The incident record names the standard, not just the reading. |
| Audit-trail integrityWhether the event record is tamper-evident and co-signed at the moment of the breach, or a mutable log entry any database operator can correct. | Mutable log. A corrected reading overwrites the prior value; there is no co-signed record and no append-only guarantee. | Append-only evidence pack co-signed at the moment of the breach. The record cannot be back-dated by whoever holds database access. |
| Permit-to-work workflowsWhether the platform reasons sensor readings against an active permit registry, or treats permits as a separate out-of-band system. | No permit registry. Hot-work and confined-space permits live in a separate paper or ERP system the sensor data never sees. | Native permit registry correlated in real time against sensor readings. A permit-vs-atmosphere mismatch fires the correlator before the supervisor walks off the bay. |
| Incident alertingWhether an alert surfaces a classified EHS incident or a raw threshold breach that someone must manually triage. | Threshold breach alert — a number fires to a dashboard or a PLC. Classification, regulatory context, and corrective routing are left to the person who reads the alert. | Classified EHS incident with regulatory context, permit state, and CCTV frame attached. The supervisor dashboard surfaces the breach already reasoned — not a raw number. |
| Role-based accessWhether views are scoped by operator/supervisor/auditor role, or every user sees the full dataset. | No role-scoping by default. The same sensor dashboard every operator sees is the same dashboard the auditor opens. Access tiers require custom engineering. | Role-scoped views by default. Operators see their bay; supervisors see their shift; investigators see the open ticket; audit reviewers see the audit pack. |
| OSHA-ready reportsWhether the platform generates a print-ready evidence pack citing the relevant standard at the moment of the breach. | No OSHA-ready output. Compliance reports are assembled by hand from sensor exports — whoever compiles the report decides what the cells say. | On-demand PDF written at the alert step with the CCTV frame, sensor reading, and permit state already cross-referenced. The PDF the auditor opens is the PDF the platform wrote. |
| Cross-signal correlationWhether the platform correlates sensor + permit + CCTV into a single reasoned incident, or fires independent single-signal alerts. | Independent single-signal alerts. A gas sensor fires its alert; the CCTV frame stays in a separate VMS; the permit lives in a paper binder. No one correlates until after the incident. | Always-on correlator across sensor + permit + CCTV. A single reasoned incident record — not three independent alerts — arrives at the supervisor channel the moment the correlator fires. |

Run the comparison on a single bay
Start the same pilot the matrix is written against — connect sensors, register permits, point Pactwell at the CCTV feeds you already run, and watch a classified incident arrive the second the correlator fires. No SCADA rip-and-replace. The EHS context layer runs alongside what you have.
Cross-check the correlator against refineries, construction, logistics yards, chemical plants, manufacturers, the broader competitor matrix, the spreadsheet comparison, enterprise FAQ, or pricing.
