Pricing

Two products, one core

Two products on one post-quantum core. ParaSend for encrypted file transfer and ParaSign for document signing. All start free with a Paramant account; scale when you need higher limits, API access, or a dedicated relay.

Free for everyday and community use, forever. Heavy users and businesses pay for the higher limits (longer links, more reads, more devices, a dedicated relay), not to unlock features. The community tier stays free.

Every plan gets the same encryption, the same post-quantum signatures and the same public proof log. Pay for volume, never for security. And pay per organisation, not per user.

Limits

Every tier stores transfers in RAM. What differs by tier is how long the link lives, how many times it can be read, and how many devices can register for verified transfers. Enterprise customers running a dedicated relay can configure limits within the RAM budget of their deployment.

Encryption

Every tier uses the same cryptography. Verified transfers via ParaShare use ML-KEM-768 plus ECDH P-256 hybrid key exchange with ML-DSA-65 signed receipts. There is no lesser encryption at lower tiers. Cryptography is not a paywalled feature at Paramant.

Compliance

All tiers meet NIS2 and GDPR requirements by design. NEN 7510, eIDAS, and IEC 62443 mappings ship with Pro and Enterprise. A signed Data Processing Agreement under GDPR Article 28 is available on request for all paid tiers.

Support

Free tier is self-service via public documentation and the CT log. Pro tier includes email support with published response targets. Enterprise customers get a named contact, a 99.9% SLA, priority incident handling, and deployment assistance for air-gapped and regulated environments.

Frequently asked questions

What happens to my file after the recipient downloads it?

All files are RAM-only. They exist only in server memory and are wiped immediately on download (burn-on-read) or on TTL expiry. Nothing persists after expiry on any tier. There is no disk storage.

Can I self-host Paramant for free?

Yes. The relay is available on GitHub under BUSL-1.1. Community self-hosting is free forever. The license prevents competitors from reselling the relay as a managed service without a commercial license. See the license page for full terms.

Is there a free trial for Pro?

There is no separate trial: every product has a free tier forever, so you can try the core flow at no cost and upgrade to Pro or Business when you need higher limits. Create a free account to start, no card required; the Pro and Business buttons above take you straight to checkout.

How does ParaSign pricing work?

ParaSign is priced by signature volume, not by feature. Free covers 2 signatures a month; Pro (€49/mo or €499/yr) includes 100 a month, then €0.40 each, with API access; Business (€299/mo) includes 1,000 a month with named support and an exportable audit log. Every tier uses the same ML-DSA-65 post-quantum cryptography and public CT-log verification. Signatures are advanced (AES), not qualified (QES). QES is coming via an EU QTSP partner.

Do all plans include a GDPR Data Processing Agreement?

The standard DPA is publicly available at /dpa and applies to all plans. Enterprise customers can negotiate custom DPA terms as part of their contract.

What does "IEC 62443 / NEN 7510 / NIS2 compliance documentation" mean?

Architecture documents, security controls mappings, and technical reference materials aligned to these frameworks. This is documentation you can use as input for your own compliance process. Paramant does not hold third-party certification for these frameworks.

What happens if Paramant shuts down?

Paramant is published under BUSL-1.1. If the managed service ever closes, every self-hosted relay keeps running indefinitely. The source code is permanently available on GitHub. No vendor lock-in by design.
