Generic page-change monitors like Visualping, Distill, or Wachete are good tools. If your job is "tell me when this web page changes," they do it well and cheaply. Plenty of compliance teams begin exactly there — pointing a page monitor at a vendor's privacy policy and waiting for the email.
The question isn't whether they work. It's whether "a page changed" is the thing you actually need to know.
What a generic monitor tells you
A page monitor watches a URL and pings you when the pixels or the text change. That's genuinely useful — it's the difference between finding out about a policy change today versus at your next annual review.
But the alert stops at the diff. It says "this page is different." It doesn't say whether the difference matters. And with vendor compliance documents, most changes don't — a reformatted footer, a new cookie-banner, a marketing line. The monitor flags all of them with equal confidence, and after the third false alarm, people stop reading the alerts.
Where compliance-native monitoring is different
Thorgate is built for one document class — vendor privacy policies, terms, DPAs, subprocessor lists, and security pages — and that focus is the whole point.
- It knows what it's reading. A DPA is not a pricing page. Thorgate treats document types differently and knows which changes carry compliance weight.
- It classifies by impact. Every change is tagged major, moderate, or minor. A new subprocessor is major; a reworded sentence is minor. You read the majors and skim the rest.
- It filters cosmetic noise. Whitespace, reformatting, and version-number bumps are detected but suppressed from alerts — the thing that makes generic monitors exhausting.
- It keeps version history. Every past version is stored and timestamped, so you can show an auditor exactly what a vendor's DPA said in March versus November.
- It produces audit evidence. CSV and PDF exports formatted for SOC 2 CC9.2 and ISO 27001 Annex A.5 — not something a general-purpose monitor even attempts.

When a generic monitor is the right call
If you track a couple of vendors, don't have audit obligations, and just want a heads-up when something moves — a generic monitor is the pragmatic choice, and it's cheaper. There's no reason to over-buy.
The line to watch for: the moment you find yourself manually interpreting every alert — opening the vendor's page, figuring out what actually changed, deciding whether it matters, and writing it down for evidence — you've started doing by hand exactly what compliance-native monitoring does automatically. That manual interpretation is the real cost, and it's the cost Thorgate removes.
