Stop prompt injection before it lands

An employee opens an AI tool to draft a proposal. A prompt injection hidden in a web page is now riding their session. SalienceCyber.ai catches it at the browser plane — before it lands.

A web page the employee opens carries a hidden instruction. The assistant reads that page and cannot distinguish the instruction from the user's own request — there is no signature to match, because the text is novel. Salience Cyber reads the intent at the browser plane and neutralizes the interaction there. The steps that would have followed — reading the user's mail, and posting its contents to an attacker-controlled endpoint — never occur.

Catch it in the session

Direct and indirect prompt injection — including payloads hidden in a web page — surfaced at the browser plane as the interaction happens.

Comprehend

Read the intent

The CognitionAI Engine reads the intent inside the prompt, distinguishing a benign request from an injected instruction with no known signature.

Neutralize

Before it lands

Neutralize the injected interaction at the point of use — before it exfiltrates data or opens a connection — with no analyst in the loop.

Intent Inside the Interaction

The captured exchange, scored for anomaly, sentiment, and hostility — read at the semantic layer rather than matched against a signature.
