We offer Adobe-trusted organizational verification (OV) that adds a visible green checkmark in Acrobat, indicating that a document is sealed, tamper-evident, and issued by a verified entity. Trusted Signatures makes this process fast, affordable, and accessible—even for small and mid-sized teams. Our service is ideal for use cases where the document doesn’t require interactive signing, but still must be trusted, compliant, and verifiable. Examples include financial reports, client disclosures, healthcare forms, insurance notices, internal compliance records, audit documentation, and real estate communications. If your organization produces documents that need to stand up to scrutiny—by auditors, regulators, clients, or internal leadership—Trusted Signatures can help. \*\*Key benefits for Software Advice users:\*\* - Adobe-recognized OV signatures with green checkmark verification - Seals prove origin, authenticity, and integrity—no plugins needed - Simple to implement with CLI, API, or Zapier—no complex IT project - Documents never leave your infrastructure during sealing - FIPS 140-3 Level 3 compliant HSM key protection and zero-trust security model - HIPAA- and audit-ready by design - Use Trusted Signatures’ OV certificate (like DocuSign) or bring your own - Pay-as-you-go model—no subscription, no lock-in Unlike DocuSign or Adobe Sign, we don’t manage signer routing or require user interaction. Instead, we help teams cryptographically seal and validate finalized documents that are ready to be sent, stored, or submitted. We make enterprise-grade trust possible without needing enterprise-grade budget, staffing, or setup. Legal, compliance, finance, and business operations professionals choose Trusted Signatures when they need security and proof—not complexity. We help you build trust into your documents in a way that’s simple, verifiable, and scalable. If your organization creates high-value PDFs but doesn’t need full e-signature workflows, Trusted Signatures gives you the protection you need—with tools built for the way your team already works. > > Verdict: Rated \*\*\*\* by 0 users. Top-rated for **Overall Quality**. ----- ## About the vendor - **Company**: Trusted Signatures ## Commercial Context - **Starting Price**: US$10.00 - **Pricing model**: Usage Based (Free version available) - **Pricing Details**: Pay-As-You-Go — No Subscriptions Required Every PDF you seal is billed individually, with rates that adjust automatically based on your monthly usage. You can get started with as few as 10 seals, and there are no user limits or subscription fees. There's no need to pre-purchase a plan or commit to a contract — you only pay for what you use, and pricing scales automatically as your volume increases. Cumulative Tiered Pricing Trusted Signatures uses a monthly billing cycle with automatic volume-based tiering. Each document you seal using our Trusted Signatures OV certificate (just like DocuSign) contributes toward your usage total for the month. The more seals you generate within a billing cycle, the lower your per-seal rate becomes. Every signature is billed at its tier’s rate, and your cost adjusts automatically as your usage grows — no manual plan changes required. Example: - First 100 seals might cost $0.10 each - Next 400 may drop to $0.05 each - Beyond 1,000, you might pay as little as $0.001 per seal Use the estimator tool on our website to forecast your expenses with different scenarios. By default, documents are sealed using Trusted Signatures’ OV certificate, backed by Adobe and listed on the AATL. This allows teams to benefit from cryptographic verification without purchasing or managing their own digital certificate. For organizations that require their own branded OV certificate, we offer managed certificate provisioning and integration. Reach out to our team to learn more about using your own certificate with Trusted Signatures — we handle the heavy lifting. Secure, Accessible, and Affordable At Trusted Signatures, we believe best-in-class security shouldn’t come at enterprise-only prices. Every document sealed through our platform is backed by Adobe-trusted Organizational Verification (OV), powered by the same cryptographic infrastructure used by industry leaders like DocuSign and Adobe e-Sign. That includes FIPS 140-3 Level 3 HSM protection, zero-trust architecture, and key management built on AWS — one of the most secure and compliant environments commercially available. We never expose your signing keys. They’re created, stored, and used entirely within hardened, audit-ready HSMs—just like the gold-standard providers. And yet, our cost is often a fraction of what others charge. Why? Because there’s no technical reason digital sealing needs to be expensive. We’ve removed unnecessary workflows, user-based pricing, and manual support overhead to offer enterprise-grade trust tools at a price point that actually makes sense for engineering and compliance teams. With Trusted Signatures, you're getting the same level of assurance—from cryptographic security to Adobe recognition—without paying for bloated features or legacy pricing models. Real-Time Usage Transparency Every subscriber gets access to a live usage log and a secure billing dashboard. You can see seals issued, tiered pricing applied, and usage trends in real time — no guesswork or hidden charges. Your billing page also includes complete usage history for auditing and cost tracking. Designed to Grow with You This model rewards higher volume users without penalizing those who are just getting started. Whether you’re sealing 20 documents a month or 20,000, your cost is tied directly to value—not to arbitrary flat fees. We intentionally avoided “per user” pricing or bundled subscription plans. Our goal is to help engineering, compliance, and ops teams adopt cryptographic trust tools without waiting for budget approvals, contract negotiations, or sales demos. If you ever have questions about pricing, billing, or technical usage, our support team is available and knowledgeable. We’ll help you interpret your usage logs, optimize your integration, or prepare a custom volume estimate based on projected needs. - **Target Audience**: 2–10 - **Deployment & Platforms**: Cloud, SaaS, Web-based - **Supported Languages**: English - **Available Countries**: Albania, Andorra, Austria, Belarus, Belgium, Bosnia & Herzegovina, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Faroe Islands, Finland, France, Germany, Gibraltar, Greece, Greenland, Guernsey and 34 more ## Features - API - Access Controls/Permissions - Activity Dashboard - Approval Process Control - Audit Trail - Authentication - Compliance Management - Data Security - Drag & Drop - Electronic Signature - Encryption - Mobile Access ## Integrations (1 total) - Zapier ## Support Options - Email/Help Desk - FAQs/Forum ## Category - [Digital Signature Software](https://www.softwareadvice.co.uk/directory/4235/electronic-signature/software) ## Links - [View on SoftwareAdvice](https://www.softwareadvice.co.uk/software/529530/Trusted-Signatures) ## This page is available in the following languages | Locale | URL | | en | | | en-AU | | | en-GB | | | en-IE | | | en-NZ | | ----- ## Structured Data
