Prevent
quantum computers
from modifying your
digitally signed
documents
SignQuantum is the post-quantum security add-on which protects your digitally signed business-critical documents against the time travel cybersecurity attack posed by quantum computers.
Integrates seamlessly with top e-signature software or your custom solution.
Malicious actors will be able to backdate
and modify the content and signature
of digitally signed documents.
Every single document you sign digitally today is now proven to be tamperable with a retroactive effect.
Highly valuable legally binding documents are guaranteed to lose authenticity in the future, meaning that the obligations contained within them will become impossible to enforce by law.
Any expert witness will confirm with absolute certainty that the fake document was signed by the same representative (private key) as the original one.
Quantum computers will be able to break current digital signatures and modify the content of your digitally signed documents.
Quantum computing will soon break today's security standards such as cryptography protecting digital signatures. This poses immediate legal and financial dangers to you and your organization.
Digital signature providers aren’t addressing the quantum threat yet.
Despite not being enforced by law yet, companies that genuinely prioritize their customers' cybersecurity (like Apple, Google) already implemented the necessary post-quantum cryptography, since they recognized the retroactive effects.
Current regulations already mandate quantum resistant encryption. New regulations will mandate quantum resistant digital signatures too.
Stay ahead of regulations and competitors who still rely on outdated technology. Future-proof your workflows to ensure compliance and maintain the integrity of digitally signed documents.
Lock down your digitally signed documents and agreements with quantum-safe technology. Don't risk paying the price in courtrooms and balance sheets tomorrow.
SignQuantum use cases: securing digitally
signed documents against modifications.
Organizations rely on SignQuantum to safeguard their assets while strengthening the security and trust of partners and clients.
Enhance trust and resilience with quantum-resistant cryptography and timestamps, protecting mission-critical agreements from quantum computing enabled fraud.
Bank loan agreement
Life insurance agreement
Waiver of Intellectual Property Rights
Government procurement agreement
Manufacturing and Supply chain agreements
You are working for a bank and someone modifies a loan agreement that you signed digitally by changing the amount from $700,00 to $7,000 and changes the loan maturity date.
The same can happen with credit contracts or mortgage agreements.
Quantum computers will soon be able to alter these documents, exposing your bank to fraud and costly legal disputes.

How does SignQuantum protect your digitally
signed documents from quantum attacks?
SignQuantum is unique in the market in solving two problems at once: maintaining digital signature authenticity and securing timing proof.
Self-hosted quantum-resistant e-signature add-on
Guarantees the digital signature authenticity by integrating with existing e-signature software without requiring modifications to current processes or workflows. The add-on automatically cross-signs the document signed with today's standard algorithm by your current provider with NIST's recommended post-quantum algorithm.
Quantum-resistant blockchain technology
Provides timestamps that can be trusted without a third party. The original document to be cross-signed with post-quantum cryptography, will have its hash uploaded to the quantum-resistant QAN Enterprise Blockchain hosted on-premises. Additionally, document hashes can be added to a public blockchain as needed.
Highlighted features of SignQuantum
Self hosted on your infrastructure
Self-hosting puts you in complete control of your cryptographic keys and post-quantum signing workflows. Run it on bare metal or in the cloud of your choice depending on your infrastructure model.
Using NIST's PQC standards
SignQuantum uses NIST’s primary-recommended FIPS 204 standard ML-DSA, a digital signature scheme based on CRYSTALS-DILITHIUM post-quantum algorithm to cross-sign documents.
Branded certificate
Branding is essential to your identity, which is why the software enables you to generate fully customized certificates that reflect your organization’s visual identity.
Configurable to meet all applicable regulatory requirements
The software’s flexible configuration options enable compliance with data protection laws like GDPR, industry standards, and regional regulations by adapting to your specific legal requirements.
How does SignQuantum work?
Fully automated, self-hosted solution designed for enterprise needs.
SignQuantum integrates with top e-signature software (e.g.: DocuSign, Signaturit, Dropbox Sign, PandaDoc, Adobe Sign) and is customizable for any digital signature provider.
SignQuantum automatically signs the document with today's standard algorithms and a secondary post-quantum signature, using NIST's recommended post-quantum algorithms.
The original document hash is recorded using immutable quantum-resistant blockchain technology which makes tampering with timestamps mathematically impossible.
Document hashes and timestamps can be queried at any time on the self-hosted QAN Enterprise Blockchain. Document bodies are accessible in the software's self-hosted database.
SignQuantum and the QAN Enterprise Blockchain run on your own servers installed with Kubernetes, Docker Swarm, or Virtual Machines (VMs).
Key components like storage (S3), databases, email services, and logging tools are bundled with SignQuantum but can be easily replaced with your existing solutions to fit your requirements.
