Secure Exchanges

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.

Siggy

Siggy is Australian-owned and hosted electronic signature software for professional practices — accounting, legal, allied health and NDIS providers. Upload a PDF, place signature fields and send. Your client signs from any device through a secure link, with no account required. Every completed document comes back cryptographically sealed, with a Certificate of Completion and a full audit trail, aligned with the Electronic Transactions Act 1999 (Cth). Data is hosted in Sydney. Pricing is flat: a free plan, and paid plans from A$10 a month, with envelopes and team seats included rather than charged per signature or per user. Features include reusable templates for engagement letters, service agreements and consent forms, sequential and parallel signing, reminders, folders and search, SMS delivery, access codes, bulk send, and an API. Identity verification runs inside the signing step: a client's identity is checked against official government records, with consent, in minutes.

Sigined

Sigined is an e-signature platform for small firms. Send documents for signature by link, let clients sign from a phone or computer, and manage completed documents in one place. Basic starts at $9 per month for up to 50 documents. Account creation does not require a payment card.

Sign

Sign is an electronic signature platform built for individuals, freelancers, and small teams who need a signature that holds up, not a platform sized for an enterprise procurement team. Upload a document, drag signature, date, initials, text, and checkbox fields onto the page for each signer, and send. Recipients open a private link and sign; no account or app is required on their end. Every view, consent, and signature is timestamped and logged, with a document hash taken before and after signing, meeting ESIGN Act and UETA requirements for a legally binding signature. Unlike most e-signature tools, Sign never charges per seat. Plans run from a permanently free tier (3 envelopes a month, no card required) to $19 a month for unlimited envelopes. Templates save a document's field layout for anything you send repeatedly, and reminders, both automatic and manual, follow up with signers who've gone quiet.

SignaTrust

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.
