Keep the form open. Close it to bots.
A contact form or quote request is usually the least-defended page on a site, and the most directly connected to sales pipeline. MTCaptcha verifies it invisibly, so the form stays easy for a real prospect and closed to the scripts that would otherwise fill a CRM with noise.
This is the real widget, live, not an illustration. Try it above the way a visitor to yoursite.com would.
What form spam costs beyond the annoyance
Form spam is the oldest bot problem on the web and still one of the most underrated, because the damage is diffuse rather than dramatic: no breach, no outage, just a slow accumulation of fake leads, throwaway-email signups, and scripted comment submissions that someone eventually has to sort through by hand.
On a sales-facing form specifically, the cost compounds, a scripted submission looks like a real inquiry until a rep spends time on it. On a signup form, it inflates account counts with users who never arrive. Both distort the numbers a team makes decisions from.
Where it actually shows up
Sales time goes to fake leads
Every scripted submission that reaches a CRM as a "new lead" is a real prospect's inquiry sitting in the same queue, competing for the same follow-up time.
Signup funnels get diluted
Throwaway-email and scripted signups inflate top-of-funnel numbers without ever becoming real usage, making the funnel look healthier, or worse, than it is.
Comment and review sections carry reputational risk
Unmoderated spam in public-facing comments or reviews reflects on the site hosting it, not just on whoever posted it.
It scales for free, for the attacker
A form with no verification costs an attacker nothing extra to hit at ten times the volume, the cost all lands on whoever has to process what comes through.
How MTCaptcha keeps the form open
No puzzle for the visitor who was always going to fill it out honestly.
Invisible NoCAPTCHA by default
Verifies the submission in the background, most real visitors complete the form exactly as they would with no protection on it at all.
Adaptive risk engine
Scores submission velocity and behavioral pattern per form, so a burst of scripted submissions gets caught even when each one looks superficially valid.
WCAG 2.1 AAA-conformant fallback
On the rare submission that does need a visible challenge, it stays solvable for every visitor rather than trading spam-protection for lost real submissions.
GDPR-compliant, no invasive tracking
Filters scripted traffic without adding cookies or fingerprinting to a form that's often a visitor's first contact with the site.
