The problem
AI made fake messages look real.
We used to look for visible mistakes: broken logos, strange domains or suspicious wording. Today a scam can be written by AI, sound perfect and arrive through email, WhatsApp, Telegram, QR, support, invoices, tickets or workflows. The problem is no longer only analyzing the message: it is knowing what action it asks for before acting.
One core, three uses
What do you want to protect?
The same chain — what is asked, who is asking, what gets authorized and what evidence remains — applied to your case.
Personal protection
A scam can cost you much more than a coffee. SecureStamp Personal costs less than one.
Before you pay an invoice, scan a QR code or share a password, SecureStamp shows you what the message is asking for and what is known about who sent it.
- What the message asks for, before you act: pay, sign in, change a bank account.
- Whether a WhatsApp number, a Telegram account or a domain belongs to the official perimeter the organization declared.
- The analysis runs on your device: the message content does not need to leave it.
A simple signal before action.

Possible impersonation, suspicious domain or risky pattern.
For companies
If someone impersonates your company, give your customers a way to notice before they pay.
Register domains, emails, phones, bots and channels so customers, vendors, employees, systems and agents can recognize legitimate communications before replying, paying or sharing information.
Signal verifies membership in the official perimeter. It does not guarantee that every message is true.
- 01
Register official domains, emails and channels.
Declare the perimeter your audience should recognize: domains, senders, phones, bots, links and public trust channels.
- 02
Publish verifiable trust signals.
SecureStamp creates references that customers, vendors, plugins, APIs and agents can query before action.
- 03
Reduce confusion around AI impersonation.
Give people and systems a practical signal before payment requests, vendor changes and sensitive workflows.
Execution Authorization
Your agent may have access. You decide the exact effect.
Access is not authorization to act.
Giving software access to a system is not the same as approving what it may change there. SecureStamp turns an approved decision into a signed, single-use authorization for one exact effect — and keeps the evidence.

Agent may call the payment processor's refund APIs

Authorize the effect, not just access to the tool.
Public BetaWorks with the controls you already have. SecureStamp does not replace identity, policy engines or approval workflows — it binds their approved decisions to exact executable effects, at an execution point you keep.
Test an agent's limits before it acts.
BetaA lab tries to break the limits you declare — by MCP, shell, script or API — and watches the result from outside the agent. Only the exact change you reviewed can leave.
How it works
One trust check before action.
An origin is declared
An organization registers domains, emails, channels, bots, phones, links or official contact points.
SecureStamp checks signals
The system reviews origin, channel, technical signals, registered status and declared intent.
You get a clear verdict
Before clicking, replying, paying, sharing data or allowing an agent to act, SecureStamp shows a trust signal.

Visual layer
The stamp is visual. Verification happens in real time.
Artwork can make registered identities easier to recognize, but operational trust always comes from the live status returned by SecureStamp.
How a stamp is verified
Stamp
Stamps add a visual and collectible layer to registered identities. But trust does not depend on an image: it depends on the token, registry and live verification.
Status indicator
The plugin or checker shows a simple state: verified, probable, review or high risk. The state is queried in real time against SecureStamp signals.
Live backend
The plugin, checker and backend query the real state of the origin before showing a signal.
