A decade of online closings taught us exactly what you need
From national lenders to the country's largest title underwriters, the most forward-thinking companies in real estate run their digital closings on Proof. Here's what they found.
Shorter closing timelines
Eliminate scheduling delays, overnight shipping, and wet-ink re-signs. Online closings happen on your borrower's timeline — nights, weekends, across state lines.
Industry-leading fraud protection
Hundreds of identity checks with a complete, tamper-evident audit trail. Proof gives you more confidence in every signer than any in-person closing can.
Built for lenders and title together
Proof is designed to align lenders and title agents on one platform. From eNote setup to closing package delivery, both teams work in sync — no dropped balls, no duplicate data entry.
Plugs into your existing workflow
Native integrations with Encompass, Resware, and other leading LOS and title platforms mean your team doesn't have to change how they work — just how fast they close.
A closing experience borrowers love
4.7 out of 5 stars from over 20,000 verified reviews. Proof helps lenders and title agents offer a closing that stands out.
Robust identity verification
Proof runs credential analysis, liveness detection, and knowledge-based authentication to meet signer verification requirements across states and underwriters.
“Proof makes it easier to serve our borrowers, especially when speed matters. It’s a seamless experience for brokers and clients alike.”
The only closing platform with real-time deepfake detection
Deed fraud and seller impersonation have always been a risk. Now fraudsters are using AI to fake identities on live video calls. Defend is the only closing platform that detects deepfakes during an online notary meeting — plus flags risk signals across every transaction automatically.
