The short version
Who Prompt Security is for
Enterprises that want broad visibility and control over how employees and applications use GenAI, with real-time blocking of risky prompts and data leaks across many LLM providers.
Visit Prompt SecurityThe honest verdict
Prompt Security and AxioRank both sit inline and both want to stop a bad AI interaction before it causes harm. The difference is what each is built to do. Prompt Security is a strong GenAI runtime-security and data-protection layer: it inspects every prompt and response in real time, blocks injections and data leaks, gives security teams visibility into shadow AI, and runs an MCP gateway in front of known servers. It is now part of SentinelOne. AxioRank is an inline control plane that issues the agent a short-lived identity of its own, decides allow, deny, or hold on every tool call against your policy, tracks how a sequence of calls composes into an attack, and writes a tamper-evident, offline-verifiable receipt for each action. If you want enterprise-wide GenAI visibility and real-time content controls, Prompt Security is an excellent fit. If you need provable evidence of every agent action and identity that an auditor can check independently, that is where AxioRank is built to win. The two operate at different layers and many teams run both.

On the hot path
Inspect the prompt, then decide the call and prove it
Prompt Security inspects every AI interaction in real time and blocks high-risk prompts before they reach the model. AxioRank sits inline on the agent's tool calls and goes one step earlier and one step later. It issues the agent a short-lived identity of its own, decides allow, deny, or hold on every tool call against your policy while it scores the payload, and writes a receipt for the decision. Walk a real call through the gateway below and watch each stage make its decision.15

Content inspection
What the detectors see, and what gets stored
Both products inspect inputs and outputs for prompt injection, secrets, and PII, and Prompt Security can redact or tokenize sensitive values on the fly. AxioRank runs its own detectors inline, then redacts sensitive values before they are written to the audit record, so the evidence trail never becomes a second copy of your secrets. Paste a payload and see exactly what AxioRank flags and what it would store.16

Beyond a single payload
From flagging a message to tracking the chain
Prompt Security flags the risky prompt or response in the moment. AxioRank tracks how a whole sequence of calls composes into an attack: read a secret, then exfiltrate it; list a table, then delete it. Build a sequence of agent actions and watch the kill-chain detector fire on the pattern, not just one risky message.17

When risk spikes
Decide what happens next, then prove it happened
Blocking a prompt stops it in the moment. AxioRank also lets you wire what happens after: quarantine the agent, revoke its keys, alert a channel, or open a ticket, in monitor mode first and then armed. Every action it takes is written to the same tamper-evident log as the call that triggered it, and an auditor can verify it offline. Build a response rule and replay a stream of events against it.15

Switching
Moving onto AxioRank
If you already run Prompt Security on your prompts and responses, AxioRank slots in at the tool-call layer without replacing it. Route an agent through AxioRank as an inline gateway or an SDK adapter, keep Prompt Security for content inspection and data protection, and let AxioRank add identity, per-call policy, and provable evidence. Most teams run the two side by side.
- 01
Point one agent at the gateway
Drop in an SDK adapter or set AxioRank as the agent's MCP endpoint. Your existing content layer stays where it is.
- 02
Run in monitor mode
Watch decisions, signals, and receipts accrue with nothing blocked, so you can tune policy against real traffic.
- 03
Arm policy and response
Turn on deny and hold, then wire automated responses. Every action is written to the tamper-evident log.
- 04
Hand an auditor the receipts
Export per-action receipts and verify them offline with the open-source verifier, independent of AxioRank.
A fair shake
Where Prompt Security fits better
A comparison is only useful if it is honest. Here is where Prompt Security is the stronger choice.
Prompt Security gives security teams enterprise-wide visibility into GenAI use, so they can adopt AI tools while keeping shadow AI and data-privacy risk in check.11
Prompt Security is fully model-agnostic, covering all major LLM providers including OpenAI, Anthropic, and Google, plus self-hosted and on-prem models.12
Prompt Security can redact or tokenize sensitive data on the fly, a data-protection capability that goes beyond what AxioRank does at the tool-call layer.13
Prompt Security is now backed by SentinelOne, folding GenAI security into the Singularity platform alongside endpoint protection. AxioRank is an independent runtime control plane and does not provide endpoint security.14
FAQ
Common questions
Is AxioRank a replacement for Prompt Security?
Not exactly. Prompt Security is a GenAI runtime-security and data-protection layer that inspects prompts and responses for injection, data leakage, and toxic content, with an MCP gateway in front of agents. AxioRank is an inline control plane focused on agent identity, per-call policy, and provable evidence. The two sit at different layers, and many teams run Prompt Security for content control alongside AxioRank for enforcement and a tamper-evident trail.
Prompt Security already blocks injections and data leaks. Why add AxioRank?
For identity, policy, and proof. Prompt Security's real-time inspection is a genuine strength. AxioRank adds a short-lived identity minted for the agent, per-tool allow and deny rules, information-flow control across a sequence of calls, and a tamper-evident receipt for every action that an auditor can verify offline without trusting AxioRank.
Where is AxioRank genuinely different?
In what it can prove. AxioRank writes each agent action to a tamper-evident, RFC 6962 style log and signs an offline-verifiable receipt for it. A public tool-definition transparency log and a published protocol coverage tracker are not features we found documented for Prompt Security as of June 2026.
Can I run AxioRank alongside Prompt Security?
Yes. They operate at different layers, so you can keep Prompt Security inspecting content and route agent tool calls through AxioRank for identity, policy, and receipts. Start with a single agent and leave your Prompt Security setup in place.
