Prompt-injection and agent-action firewall
Put LLM assistants and agents into production without letting a document talk them into acting for someone else.
PromptShield sits between your apps and your own model account. Built for teams at banks, insurers, law firms and hospitals who have to explain every decision.
The sandbox is a throwaway organisation with synthetic traffic. No sign-up needed.
Agent actions, with proof
Every tool call your agent tries is traced to what caused it — the user, a document, a tool, or nowhere — then allowed, held for approval or blocked, with a signed receipt your tool servers can verify.
Multi-turn attacks
Sessions are scored turn by turn. A drift statistic, calibrated on your own traffic, raises an alarm when a conversation slowly turns into an attack.
Data that stays put
Customer and patient data is redacted or withheld before a reply leaves. The console shows categories and fingerprints, never the values.
Evidence for reviewers
A hash-chained audit log, MITRE ATLAS technique ids on every decision, and exportable evidence packs.
How we report numbers
Detection and false-alarm rates are published in the measured scorecard, with the datasets and confidence intervals behind them. Inside the console, every number comes from your organisation's own traffic. New organisations start in monitor mode and only enforce drift after calibrating on their own sessions.
