Who Robust Intelligence is for
Teams that want pioneering algorithmic red teaming and runtime AI guardrails, now delivered at Cisco scale as part of Cisco AI Defense.
Visit Robust IntelligenceThe honest verdict
Robust Intelligence and AxioRank both guard AI at runtime, but they were built for different jobs. Robust Intelligence pioneered the AI Firewall and algorithmic red teaming, and its technology is now the core of Cisco AI Defense: it inspects model inputs and outputs for prompt injection and data leakage, red-teams models and agents with techniques like Tree of Attacks with Pruning, and turns threat intelligence into in-product guardrails. AxioRank is an inline control plane focused on the agent's tool calls: it issues the agent a short-lived identity of its own, decides allow, deny, or hold on every 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 pioneering AI red teaming and runtime guardrails at Cisco scale, Robust Intelligence 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
Screen the input, then decide the call and prove it
Cisco AI Defense screens model inputs and outputs at runtime and enforces guardrails. 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 AI inputs and outputs for injection, secrets, and PII at runtime. 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 one guardrail to the whole chain
Cisco AI Defense includes a Tool Exploitation guardrail that stops a single hijacked tool call. 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

Policy you can read
Guardrails, and per-agent, per-tool rules
Cisco AI Defense lets you specify how your application handles the violations its guardrails detect. AxioRank lets you write the rule the other way around: per-agent and per-tool allow and deny, scoped to a short-lived identity and evaluated on every call. Build a policy below and watch it decide allow, deny, or hold against live traffic.18

Switching
Moving onto AxioRank
If you already run Cisco AI Defense to red-team and guardrail your AI, 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 Cisco AI Defense for red teaming and runtime guardrails, 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 guardrail 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 Robust Intelligence fits better
A comparison is only useful if it is honest. Here is where Robust Intelligence is the stronger choice.
Robust Intelligence introduced the first-ever AI Firewall to the market, a category it pioneered ahead of the field.11
Robust Intelligence pioneered algorithmic red teaming, including the Tree of Attacks with Pruning technique, which AxioRank does not. AxioRank is a runtime control plane and does not run offensive red teaming.12
Cisco AI Defense runs adaptive, multi-turn validation of models and agents before they ship, pre-deployment testing that complements rather than overlaps with AxioRank's runtime enforcement.13
Robust Intelligence is now delivered at Cisco scale as the core of Cisco AI Defense. AxioRank is an independent runtime control plane.14
FAQ
Common questions
Is AxioRank a replacement for Robust Intelligence or Cisco AI Defense?
Not exactly. Robust Intelligence, now the core of Cisco AI Defense, pioneered the AI Firewall and algorithmic red teaming and enforces runtime guardrails. 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 Cisco AI Defense for red teaming and guardrails alongside AxioRank for tool-call enforcement and a tamper-evident trail.
Cisco AI Defense already red-teams and guardrails AI. Why add AxioRank?
For identity, policy, and proof at the tool-call layer. The algorithmic red teaming pioneered by Robust Intelligence is a genuine strength AxioRank does not try to match. 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.
Where is AxioRank genuinely different?
In what it can prove about the agent's actions. 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 Cisco AI Defense as of June 2026.
Can I run AxioRank alongside Cisco AI Defense?
Yes. They operate at different layers, so you can keep Cisco AI Defense red-teaming and guardrailing your AI and route agent tool calls through AxioRank for identity, policy, and receipts. Start with a single agent and leave your Cisco AI Defense setup in place.
