Protect real estate listings, agent contacts, and inquiries from bots
Property portals publish exactly the data other people want to take: prices, photos, and the agent's phone number. Centinel evaluates the automation behind those requests, so home seekers and approved partners keep using the portal while scrapers and spam scripts get a different response.
Request a site auditA listing page is both a public page and a data product
Listing data is expensive to collect and easy to copy. A competing portal or lead reseller can pull it page by page, and inquiry forms attract scripted spam that ends up in agents' inboxes. Blocking all automation is not the answer either, because search engines and syndication partners need the same pages. The decision is which client gets which data.
Read the researchWhat the traffic looks like
Listing data copied page by page
Scrapers walk search results and detail pages to copy prices, photos, and availability, often spreading requests across residential proxies so no single address stands out.
Agent phone numbers in bulk
Contact details revealed on a listing can be collected across thousands of pages, then resold or used for cold outreach.
Accounts and inquiries on autopilot
Scripted sign-ups can post duplicate rental listings. Inquiry forms can be submitted at scale to send spam or fake leads.
What runs against this traffic
Evidence on listing and search routes
In supported browser deployments, Centinel evaluates request and browser evidence on search, listing, and map routes.
A portal can rate-limit or challenge a scraping session without adding friction for every home seeker.
Read moreA stricter policy for contacts and inquiries
The contact-reveal action and inquiry or message submission can carry a stricter route policy than a public listing page.
Revealing an agent's number or sending an inquiry can require stronger evidence than viewing a listing. Centinel does not judge whether a message is spam; that stays with your moderation.
Read moreEvidence around account creation
In supported sign-up flows, Centinel evaluates the session around the form, not only the submitted details.
Automated account creation behind duplicate listings can be challenged or reviewed. Centinel does not verify property ownership or a landlord's identity.
Read moreKeep search crawlers and syndication partners
Centinel can compare a declared crawler identity with the verification data its operator publishes, and known partners can keep an explicit policy.
Search engines and feed partners keep their access. A scraper that copies a crawler name gets no trust from the name alone.

Real estate & proptech: common questions
What platform and security teams ask before they deploy.
What is real estate scraping?
Real estate scraping is the automated copying of property listings (prices, photos, availability, and agent contact details) from portal search and detail pages. It is usually run by competing portals, data resellers, and lead brokers, often through residential proxies.
Why do scrapers target property portals?
Listing data is costly to collect and valuable to resell. A copied listing set can seed a competing portal, and harvested agent phone numbers and emails are sold as leads or used for cold outreach.
Can a portal stop scrapers and keep search engines and syndication partners?
Yes. Search crawlers can be verified against the data their operators publish, and syndication partners can keep an explicit policy. Everything else on listing routes is judged by how the request was made, so a scraper using a crawler's name gets no free pass.
Does Centinel stop rental scams?
Not directly. Centinel does not verify property ownership or a landlord's identity. It evaluates the automation behind account creation and listing submission, so the scripted sign-ups that duplicate rental listings at scale can be challenged or held for review.
How do you stop inquiry form spam without friction for home seekers?
Give the inquiry and contact-reveal routes a stricter policy than public listing pages. A request with weak evidence can be challenged at that step, while home seekers browsing listings never see the check.
