Protect your website from spam and abuse
Secure your registration process using our proprietary dataset of people, companies and IP addresses. Receive a risk score for every signup to prevent bad actors and account abuse.
Strength in numbers
By applying machine learning to hundreds of data sources and key indicators like signup velocity and device fingerprints, we'll generate an accurate risk score that you can act on.
A flexible solution
Build the perfect solution for your business! We give you all the ingredients to easily integrate customized abuse prevention into your existing signup flow.
Enforce higher quality signups
Completely block or require additional information from low quality signups by identifying disposable email addresses, free email providers, proxy servers and VPNs. You can even require that all signups use professional email addresses to ensure your leads are high quality.
Save time and protect your assets
Don’t let spammers waste valuable resources by taking advantage of free trials, and stop manually combing through your signup lists for signs of fraud. Automatically block bad actors based on advanced heuristics like email age, social media activity, and behavior before they gain access.
Shorten your forms and increase conversion by removing CAPTCHAs for authentic signups. Allow your sales team to focus on selling instead of wasting time sifting through spam accounts.
