Agentic Security puts every AI agent and LLM behind one Pavii gateway. Pavii checks each call at six security gates before the call can do harm. Important rules live as smart contracts on Hyper 0X, the post-quantum-resistant blockchain from Buckleson. Each action gets a receipt that nobody can secretly change.

Follow one request through Agentic Security
Each request moves down the layers. A safe request reaches the end. A harmful one stops at the layer that catches it, and you see why.
- 01 One gateway, every agent Every prompt and tool call from every agent comes in through one entry point, so each call has a known sender. ClaudeCodexChatGPTCustom
- 02 Injection gate Text from web pages, files, emails and tool results is data. Pavii never runs it as an instruction. Hidden promptsJailbreaks
- 03 Privacy gate Pavii removes personal data, keys and secrets before a model sees them. Personal dataAPI keys
- 04 Supply-chain gate New packages, plug-ins and MCP servers must be on the allow-list, match a pinned hash or pass a sandbox test. MCPPackages
- 05 Budget gate Each agent has limits on tokens, spend and call rate. TokensSpendLoops
- 06 Egress contract A smart contract on Hyper 0X decides what an agent can send and do. Nobody can secretly change it. On chainApprovals
- 07 Output gate Pavii removes scripts, secrets and system-prompt text from what the agent returns. ScriptsSecrets
- 08 Kill switch An agent that breaks rules moves from observed, to restricted, to stopped. A person can stop any agent. ObservedRestrictedStopped
- Signed receipt on Hyper 0X Pavii links each decision, allowed or blocked, to the decision before it. A deleted entry shows as a gap.
- 01 Who is asking Each agent acts for a known person. Pavii attaches that person and their role to every question. PersonRoleTeam
- 02 Company brain A shared graph of documents, decisions and code that grows from daily work. Graph memoryProduct graph
- 03 Access contract on Hyper 0X A smart contract checks the role against each piece of knowledge before the agent can read it. On chainNo escalation
- 04 Privacy gate Personal data and secrets leave the answer before the model sees it. Personal dataSecrets
- Answer with only what this person can see Each read gets a receipt, so the team can see which agent read which knowledge.
- 01 You use an AI app Prompts, files and tool results can hold names, numbers and secrets. PromptsFiles
- 02 Privacy gate Pavii replaces personal data with tokens before the request leaves your side. MaskingSecrets
- 03 Proofs, not documents A zero-knowledge proof shows a fact, such as "over 18" or "verified", without the data behind it. ZKPFacts only
- 04 Usage signals The provider gets patterns that help it improve the model, not personal records. AggregatesNo raw data
- 05 Egress contract A smart contract on Hyper 0X decides which data can leave. Raw personal data cannot. On chain
- The model improves, your data stays yours Each data release gets a receipt that you and the provider can both check.
Rules and receipts live on Hyper 0X, the post-quantum-resistant blockchain from Buckleson. See how Hyper 0X works or read why receipts need a blockchain.
Protect Your Agents, Your Data and Your Users
AI agents read data, call tools and send messages for you. Pavii checks each of these actions and blocks the harmful ones. Pavii stops malicious activity, or at least makes it visible. Personal data does not leak. Model providers and agent vendors can still learn from usage, but they never get data that can harm your users.
Six gates on every call
Pavii checks each call for prompt injection, private data, unsafe packages, cost, outgoing data and unsafe output. A prompt injection is hidden text that tries to take control of an agent.
Rules that the model cannot forget
Your important rules live as smart contracts on Hyper 0X. They still apply when the context window of a model fills up and the model forgets an instruction.
A record that nobody can change
Pavii links each receipt to the one before it and anchors the chain on Hyper 0X. Nobody can secretly change or delete a record.
Injection Gate
Finds hidden instructions in prompts, files, web pages and tool results, and blocks them.
Privacy Gate
Removes personal data and secrets before a model sees them. Zero-knowledge proof designs let a provider check a fact without seeing the data.
Supply Chain Gate
Checks the tools, packages and MCP servers that an agent wants to use before it uses them.
Budget Gate
Sets limits on tokens and spend for each agent, and stops a call that goes over the limit.
Egress Gate
An egress smart contract on Hyper 0X decides what an agent can send out and what it can do.
Output Gate
Checks the answer of the model before it reaches a user or a tool.
Kill Switch
An agent that breaks rules moves from observed to restricted to stopped. A person can stop any agent at any time.
Agentic Observability
See each call, tool, blocked action and cost for every agent. Use this record to find problems and make agents better.
Company Brain
A shared graph memory built from usage. Pavii checks access on the blockchain, so the agent of a junior employee cannot read restricted knowledge.
Your Own Chain
Use the Pavii chain, run your rules on-chain or deploy your own chain inside your organization. You do not change your business logic.
