If you only need to protect forms, use Procaptcha: Free for one site up to 10K requests a month, or Professional (from $39 a month) for more traffic, up to 50 sites, filtering and AI agent rules. If bots hit your pages, API or mobile app directly, or you need more than 1M requests a month, use Enterprise (Prosopo Protect, from £1,500 a month), which learns what normal traffic looks like on your site. Choose Custom (from £2,500 a month) if you need 24/7 support, a custom SLA or data residency.

| What it checks | The forms you add it to | Every request to every page and API |
| Scrapers and API abuse | Not seen: they call your API directly | Stopped before they reach your servers |

Not sure which plan fits?
A Bot Exposure Assessment is a 30-minute call with an engineer. We look at your traffic, show where your current setup leaves gaps, and agree how a trial would be judged. Nothing to install first.

Which Prosopo plan do I need?
How much does Prosopo Protect cost?
Protect is sold as two plans. Enterprise starts at £1,500 a month (€1,750 / $1,990) with business-hours support. Custom starts at £2,500 a month (€2,950 / $3,300) with 24/7 support, a P1 response within 15 minutes, and custom SLAs or data residency where you need them. Both run on a 12-month term and are priced by the number of sites you protect. Traffic is not metered, Procaptcha for your forms is included, and there are no setup, onboarding or professional-services fees. Paying annually upfront takes 15% off.
What is the difference between Procaptcha and Protect?
Procaptcha protects the forms you add it to: login, signup, checkout, contact. It is a script tag on the form and a token check on your server. Prosopo Protect (the Enterprise and Custom plans) covers your forms, API and whole site: you add it as a script tag on your forms, an edge worker on Cloudflare Workers or AWS Lambda@Edge, or both. It checks requests to your site and API before they reach your servers, so it also stops scraping, API abuse, inventory hoarding and credential stuffing that never touch a form. Because Protect sees every request, it also learns what normal traffic looks like on your site, which a check on one form can't. Both use the same portal, and Protect plans include Procaptcha.
How much does Procaptcha cost?
Procaptcha is free for up to 10K requests a month. Professional costs from $39 a month (£30 / €35) for 100K requests, up to $139 a month for 1M, with 15% off when billed yearly and a 30-day free trial. Above 1M requests a month, Enterprise (Prosopo Protect) covers it: traffic isn't metered and your forms are covered too.
Why pay for Protect when Cloudflare Turnstile is free?
Turnstile is a widget that checks the forms you put it on. Bots that scrape pages, call your JSON API directly, hold checkout inventory or test stolen passwords against a login endpoint never load that widget. Protect checks every request to the pages and APIs you choose, names the detector behind every block, keeps processing in the EU on request on Enterprise and Custom, and starts in preview mode so you see your own traffic before anything is blocked.
Can we try Protect before committing?
Yes. Every Protect deployment starts with 14 days in preview mode: Protect checks your live traffic and records what it would have blocked, but blocks nothing. You pick a plan from your own numbers, then switch blocking on.
Which currencies can we pay in?
GBP, EUR or USD. The prices on this page are set in each currency rather than converted on the fly.
