Read & Sign is a digital signature platform for signing documents, managing policy acknowledgments, and tracking compliance. It allows users to send, receive, and store signed documents while maintaining records of engagement and approvals
Secure Exchanges is a Canadian cybersecurity company founded to address the growing need for secure digital communications in Canada and internationally. The company develops and operates a cloud platform dedicated to protecting sensitive data exchanges. Its solutions serve businesses, professional firms, financial institutions, government agencies, and healthcare organizations that need to safeguard the confidentiality of their daily communications. The platform is available in English and French. The platform offers three core capabilities: end-to-end encrypted email, secure large file transfer supporting files up to 25 GB, and Adobe AATL-certified digital signatures. All communications are protected by AES 256 encryption and a zero-knowledge architecture, meaning neither Secure Exchanges nor any third party can access exchanged data or encryption keys. The solution integrates directly into Outlook and Gmail as a plugin, requires no IT team for deployment, and allows recipients to receive and reply securely without a license. Secure Exchanges addresses a critical challenge for organizations subject to confidentiality requirements: securing sensitive data exchanges without adding complexity to existing workflows. By integrating into the email tools already in use, the platform eliminates the friction typically associated with encrypted communications. Compliance with Quebec's Law 25 and the European GDPR, combined with SOC 2 Type II certification, enables organizations to meet their regulatory obligations for personal information protection and data security.
SignaTrust is a zero-custody e-signature platform that anchors every signed document to the blockchain, creating immutable proof of execution verifiable without any vendor. Every signing generates a cryptographic hash on a public blockchain that no party can alter, creating court-admissible permanent evidence. Three-tier signer verification with SMS OTP, biometric, and device-bound passkeys closes the bearer-token vulnerability where forwarded signing links are exploited, included on every plan. AI-powered analysis flags risks, unusual clauses, and hidden terms in plain language before signing. Documents and signing keys never touch our servers, leaving nothing to breach, subpoena, or lose. Compliance-ready for HIPAA, SOC 2, RFC 3161 timestamps, and 21 CFR Part 11 across healthcare, finance, and legal. API-first with REST API, TypeScript SDK, embedded signing, and webhooks. Native iOS and Android apps with QR scanning, offline signing, and blockchain verification.

Signatura is an e-signature platform for sending, signing and sealing documents online. Upload a PDF, DOCX, PNG or JPG up to 25MB, place the fields, and send to unlimited signers in sequential or parallel order. Signers never need an account and never pay: they open a link, sign, and get their copy. AI-assisted field placement detects signature, date and text fields and scores its confidence on each before you send. Nine field types: signature, initials, date, text, checkbox, dropdown, attachment, auto-number and image. Recipients can decline or request changes, not only sign. Every completed document is sealed with a SHA-256 hash and a full audit trail of who signed, when and from where, delivered as a Certificate of Completion that anyone holding the file can verify without an account. TLS 1.3 in transit, AES-256 at rest, 2FA. App, signing pages and emails run in seven languages, chosen per recipient. Imports from Google Drive, Dropbox and OneDrive. Custom branding throughout.
