Corporate communications are under unprecedented pressure. The rise of generative AI has dramatically accelerated the production and circulation of fake news: fabricated press releases, manipulated earnings announcements, altered regulatory filings.
A fraudulent document can move markets, damage reputations, and trigger regulatory scrutiny before the originating company even becomes aware of the forgery. Journalists, investors, and financial analysts can no longer rely solely on a document appearing in an email or on a third-party site as proof of its legitimacy.
The consequences are particularly acute for listed companies and regulated entities. A manipulated quarterly report or a falsified press release attributed to a CAC 40 group can create immediate and measurable reputational and financial harm. Traditional verification methods, such as contacting a press office or cross-checking against a corporate website, are too slow for today's real-time information cycles.
Wiztrust Protect is a blockchain-based certification and verification product developed by Wiztrust, a PR software specializing in corporate communications and PR management for financial institutions, insurance companies, and large industrial groups.
Every press release, financial disclosure, or corporate document published through Wiztrust is automatically anchored to a blockchain at the moment of publication. This creates a tamper-evident digital fingerprint that is permanently and immutably recorded. The document's integrity can be verified at any time, by anyone, at no cost.
Wiztrust Protect is a free verification tool open to everyone, including:
Verification requires no account, no registration, and no technical expertise. The entire process takes under one minute.
Open your browser and navigate to protect.wiztrust.com/en. The platform is publicly accessible and requires no login.
On the homepage, click the "Check your file" button. This opens the document upload interface.
Select and upload the press release or corporate document you received. Wiztrust Protect computes the document's cryptographic hash and cross-references it against the blockchain record created at the time of the original publication.
The result is immediate and unambiguous:
Wiztrust Protect does not require journalists or investors to trust a vendor's word. The verification is performed against an immutable blockchain record that no party, including Wiztrust itself, can retroactively alter. This makes it a genuinely independent verification mechanism.
For communications teams at listed companies, every document published through Wiztrust automatically inherits this verification infrastructure. For the recipients of that content, whether a financial journalist working under deadline or an analyst conducting due diligence, the tool provides a definitive answer in under a minute.

Why does blockchain matter for corporate communications?
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. Learn more on how to protect yourself against fake news.
Is Wiztrust Protect free to use?
Yes. Wiztrust Protect is a free verification service open to anyone who receives a corporate document and wants to confirm its authenticity. No account, subscription, or login is required.
What types of documents can be verified?
Any document distributed online including press releases, earnings announcements, regulatory filings, investor communications, and other official corporate publications.
What should I do if a document fails verification?
A failed verification means the document in your possession does not match the original certified version. You should contact the issuing company directly through official channels to obtain the authenticated original, and treat the unverified document as potentially modified until confirmed otherwise.
How does blockchain certification prevent document tampering?
At the moment a document is published via Wiztrust, the platform computes a unique cryptographic hash of the file and records it on a blockchain. This hash acts as a digital fingerprint. Any modification to the document, even a single character, produces a different hash, making alterations immediately detectable during verification. Wiztrust Protect certifies a broad range of content formats including press releases, earnings announcements, financial reports, PDF documents, images and videos.
