# Alternative data > Reliable, fresh, defensible access to the dynamic and protected web sources your alternative-data signals depend on. One production platform instead of a scraper farm you babysit. ## Turn the live web into investment-grade signal. The dynamic and protected sources your signals depend on, delivered as one production feed. Not a scraper farm you babysit. - hiring velocity +412 roles fresh · 6m - listing supply 18,204 live fresh · 6m - price index $49.00 fresh · 6m - review sentiment 4.31 avg fresh · 6m Illustrative · refreshed on your run ## The source breaks. The series rots. Protected pages block. Dynamic apps return empty shells. Gaps and lag corrupt the time series your model trusts. ## Four primitives keep the feed alive. The reliability layer between your models and the human web. Open a line to see what it does. - 01 Extract Raw pages become structured rows. Dynamic, protected pages in. Clean JSON out, with the schema your series expects, every run. - 02 Batch The whole universe, not a sample. Push an open queue of sources. Workers drain in parallel and deliver per source, at the scale a signal needs. - 03 Fetch Protected pages become readable input. Anti-bot bypass and JS rendering retrieve the page reliably, so extract always has clean input to work from. - 04 Browser Sessions Interactive sources stay reachable. Logins, clicks, and multi-step flows run in a real browser session when a static fetch can't reach the data. ## A signal you can stand behind in review. In finance, defensible beats clever. Public web data, policy-aligned access, and a trail your compliance desk can read. - 01 Public web data Access aligned to our public web data policy. - 02 Auditable access Every run logged, inspectable per source. - 03 Procurement-ready SOC 2, DPA, SSO, and RBAC in the box. - 04 One platform One vendor to review, not a scraper farm. Read the posture in full. [Public web data policy](https://www.zenrows.com/legal/terms) ## Pick a signal.

Review volume and sentiment parsed into a clean series. Location and activity signals pulled through a live browser session, on demand. ## Investment-grade signal, from the first call.
