Would you like a personalized demonstration of how Wiztrust Protect can protect your reputation and ensure your message is trusted by investors and markets?
Below are the most frequently asked questions communications teams have about how Wiztrust Protect works.
Wiztrust Protect is a product of Wiztrust that uses blockchain technology to certify the authenticity, integrity, and timestamp of corporate content at the moment of publication. When an organization publishes a press release, financial document, or official statement through Wiztrust, Wiztrust Protect creates a cryptographic hash of that content and records it permanently on the blockchain, producing an unalterable proof of origin.
This matters because corporate communications are increasingly vulnerable to manipulation: documents are screenshot-edited, statements are misquoted out of context, AI-generated deepfakes are weaponized as misinformation, and fake news spread faster than corrections. Blockchain certification solves the provenance problemby proving what it said, when it was published, and that it hasn’t been modified since.

Wiztrust Protect is designed for any organization that publishes sensitive or high-stakes content, regardless of listing status. Unlisted companies, private equity firms, and asset managers use Wiztrust Protect to certify financial communications, fund documentation, and investor disclosures where authenticity and traceability are non-negotiable. Whether or not you are subject to AMF or SEC disclosure obligations, if you publish content that could be altered, misquoted, or contested, Wiztrust Protect provides the blockchain-based certification layer that proves your version is the original.
Wiztrust Protect certifies a broad range of content formats typically used in corporate and financial communications. This includes press releases, earnings announcements, financial reports, PDF documents, images and videos. Each piece of content receives a unique cryptographic fingerprint recorded on the blockchain at the moment of publication. This means that if a document is subsequently altered, screenshot-edited, or misrepresented, the discrepancy can be detected instantly by comparing it against the certified original.
For organizations managing crisis communications, investor relations content, or ESG reports, format-agnostic certification ensures that every asset carries verifiable provenance.

No account is required. Wiztrust Protect is built around open verification: any journalist, analyst, or investor can verify the authenticity of a certified document directly from the verification portal, without registering or logging in. They simply upload the document or drag-and-drop the content, and the system instantly cross-references it against the blockchain record to confirm whether it matches the certified original, and when it was first published.
This frictionless verification model is deliberate. Trust only works if third parties can verify independently. For media professionals tracking fast-moving stories, or institutional investors performing due diligence, the ability to authenticate a source document in seconds, without any dependency on the issuing organization, is what gives Wiztrust Protect its credibility.
Misinformation targeting listed companies is a documented, recurring threat with measurable financial consequences. In 2015, a fake press release falsely attributed to Vinci announced the dismissal of its CFO and a major accounting restatement. Within minutes of the document circulating, Vinci’s stock dropped nearly 20% before trading was suspended. The damage in market value, investor confidence, and media coverage was immediate.
Wiztrust Protect addresses this attack vector directly by certifying every official communication at the moment of publication using blockchain technology, creating an immutable, timestamped proof of authenticity. When a document claiming to come from your organization surfaces, journalists, investors, and regulators can verify in seconds whether it matches the certified original on record. If it doesn’t, the fake is exposed before it can move markets.
To date, Wiztrust Protect has certified over 1.2 trillion euros worth of protected content across its client base, reflecting both the scale of adoption and the stakes involved in corporate communications integrity.
