Proof Notarize vs Secured Signing

Proof Notarize provides remote online notarization for business workflows and important documents. Proof says its Notarize Network is available on demand 24/7, 365 days a year, and that its notarizations are accepted in all 50 states. Identity checks use credential analysis, knowledge-based authentication, and biometric comparison. A business can bring its own notaries or use the network, and a notary can request an on-demand witness during a signing. Businesses can apply their logo and colors. Proof lists use in real estate, financial services and lending, business contracts, legal and estate planning, and insurance. Its Defend service analyzes video frames in real time for deepfake signals. Signers can use a phone browser without downloading an app for most transactions, though real estate transactions cannot be completed in the Notarize app. Pro+ costs $199 a month plus transaction fees and includes API access, custom branding, forms, and signing rules. Pro is billed at $0 per month plus transaction fees; higher business tiers have custom pricing.

Secured Signing is a cloud-based service for digital signatures, video signing, and remote online notarization. It supports signing alone or with others, assigning signing order, batch signing, witnessing, reminders, and editing a process after sending. Video Signing enables signatures during live video calls to verify identities and prevent later document changes. Invitees can sign without paying or creating accounts. The REST API uses JSON and supports API key or OAuth2 authentication; a.NET/C# client SDK and webhook callback are also available. Listed integrations include Bullhorn, Tracker, Duo, Okta, Active Directory Federation Services, and Microsoft Entra ID. Security details include encryption at rest and in transit, SOC 2 Type II compliance, and ISO/IEC 27001 certification. The service states alignment with ESIGN and UETA requirements in North America and eIDAS compliance in Europe. The free account allows three documents per month without a credit card. Notary Business Annual Plan costs $430 billed annually and includes 600 document uploads, with uploads up to 50 MB. Platforms listed are Android, API, iOS, macOS, web, and Windows.
