# Token Observe versus AI security platforms

Use Token Observe to govern the requests you route through its gateway. Broader AI security coverage belongs alongside it; pattern-based detection remains heuristic.

## The comparison

Use Token Observe alongside a broader AI security platform to control requests routed through the gateway. Configure action-level permissions, payload-bound approvals, spend ceilings and a kill switch for registered agents. Its pattern-based injection and personal-data detection is heuristic, can miss sensitive data and is a compensating control, not your only DLP. The shipped detectors cover nine weighted injection patterns and eleven sensitive-data classes; they do not detect arbitrary free-text personal data. Review the complete detection limits before enforcing a policy.

## Named products in this category

- Palo Alto Prisma AIRS
- Cisco AI Defense
- Zenity
- Noma
- WitnessAI
- Lakera

## Facts

- Injection detection: Nine weighted patterns, scored 1.25× on tool results
- Sensitive data: Eleven classes; card, IBAN and NHS checksum-validated
- Stated role: A compensating control, not the customer’s only DLP
- Feed direction: Your consoles push inwards; no standing broad credential

## The limit

Not a classifier: Injection scoring is fixed patterns, not a model

## Where they win: On detection, coverage and the estate that never touches a gateway, they win.

Detection quality is these vendors’ product and it is not Token Observe’s. Palo Alto publishes Prisma AIRS as a runtime firewall with discovery, model scanning, red teaming, MCP inspection and DLP, plus an AI gateway with budget limits, rate limits and rules on what each registered agent may do; Cisco publishes AI Defense as asset and MCP discovery, supply-chain scanning and runtime protection; Noma, Zenity, WitnessAI and Lakera each publish their own on prompt-injection defence and intent-aware enforcement. Every one of those descriptions is the vendor’s, untested here. Against a nine-pattern heuristic, a maintained detection product ought to win, and this product’s documentation concedes it rather than arguing: the residual risk carries a named CISO’s written acceptance.

Coverage is the larger advantage. Token Observe sees what routes through the gateway and nothing else, while a platform on the network path or in the browser sees traffic that never presents a Token Observe credential: most of the shadow AI in a real organisation. Procurement is the third: these vendors can generally hand you a certification and Token Observe cannot, and if that is your gate the comparison ends here in the other product’s favour.

## The difference, dimension by dimension

### What detection is for

Them: Detection is the product: trained classifiers, red teaming, supply-chain scanning.

Token Observe: Detection is one policy input among seven trigger kinds, published with its confidence scores so a policy can set its own threshold.

### What stops the action

Them: Runtime filtering of the traffic that matched, and in several, published rules on which tools or operations an agent may use.

Token Observe: Deny-by-default action-level permissions, an approval bound to the exact payload, a hard USD ceiling and a kill switch — the damage bounded rather than the string caught.

### Scope of the estate

Them: The whole AI estate, including browsers, unmanaged devices and agents no gateway sees.

Token Observe: Only what presents a credential to the gateway. Everything else is a radar finding, and chasing it is your work. The endpoint seat hook is preview and not production-eligible.

### Direction of integration

Them: You grant the platform access to inspect.

Token Observe: You configure an outbound feed in a console you already administer, on a credential this deployment issued. No standing broad credential runs the other way; the two shipped pull connectors, GitHub Copilot and Cisco Umbrella, are the named exception and stay off until you supply the key.

### Assurance you can buy today

Them: Ask each vendor which certifications and test results it holds, for what scope and to what date.

Token Observe: None held. A source-available licence — itself a template pending counsel — a published residual-risk register, and a 30-day evaluation written so your security team may attack it before you buy.

### What the detectors can identify.

Prompt-injection scoring is nine weighted heuristics over sanitised text, scored 1.25 times higher when the text arrived as a tool result, because indirect injection arrives through tool output far more often than through the user turn. It is not a model and it has false negatives. Sensitive-data detection is patterns too: eleven classes, three checksum-validated, confidence published per kind rather than averaged into a marketing number, and free-text personal data not detected at all.

### Limit the actions an injection can trigger.

Assume the detection missed it, because sometimes it will. What remains is the deterministic layer, and this is the part Token Observe is arguing for. Permissions are action-level and deny-by-default: an action no role names is refused, an explicit deny beats every allow, and a delegation chain intersects rather than unions. A hijacked agent inherits the authority it already had, and nothing more.

- An approval bound to one payload: Bound to the SHA-256 of the canonical action plus its execution context, single-use through a compare-and-set, expiring at 60 minutes by default. A retry with one argument changed is a mismatch rather than near enough.
- Ceilings reserved before egress: Hard USD limits per request, per rolling hour, per UTC day and per UTC month, reserved in one per-agent transaction before the call leaves. A kill switch is checked first in the pipeline.
- What it still cannot refuse: A proposal it is never shown. Tool calls the model proposes are evaluated on the way back, but an agent that routes none of its traffic through the gateway is caught by the radar, if you have fed it, or not at all.

## Choose the alternative when

- You need coverage of the whole AI estate — browsers, unmanaged devices, SaaS copilots — rather than of the agents that hold a credential you issued.
- Detection quality is the requirement: supply-chain scanning, red teaming, or a maintained injection classifier rather than nine published heuristics.
- Your procurement process requires SOC 2, ISO certification or an independent penetration test from the vendor. Token Observe has none of those.
- You are consolidating security vendors, and a second contract for a control that overlaps at the edges is a harder sell than a wider deployment of one you have.

## Choose Token Observe when

- You have one of these platforms already and the gap is the action rather than the content — what the agent was allowed to do, who approved it, whether it happened.
- The refusal has to be deterministic and explainable: a named permission, a named policy, a named approver, not a score you have to defend to an auditor.
- You want your security stack’s verdicts to become policy inputs, with your consoles pushing outwards rather than a new vendor holding a standing key.
- Self-hosted with zero vendor egress is a hard requirement, including air-gapped environments, which the licence is drafted to permit though it remains a template.

## Questions and answers

Q: Is Token Observe an AI firewall?
A: No, and the roadmap names a generic AI firewall, prompt scanner or red-team platform as one of seven strategic non-goals. The stated consequence is to consume threat and identity signals from those systems rather than lead with a complete AI security platform. Token Observe does inline PII and secret detection and injection heuristics, because a decision point that cannot see the payload cannot decide about it, but those are policy inputs rather than the product.

Q: How do we feed our security tooling into Token Observe?
A: You configure an outbound feed in a console you already administer, pointing at a receiver on a credential Token Observe issued. Vendor-shaped receivers exist for six: Cloudflare Logpush, Palo Alto Strata Logging Service, Zscaler, Netskope, Elastic and Splunk. Token Observe holds no standing broad credential into your security stack, and the two shipped pull connectors are the named exception: GitHub Copilot seat spend and Cisco Umbrella activity each hold a narrow, read-scoped key you supply into that vendor’s console and can withhold by not setting it. Everything else points inwards, so the worst a compromised deployment can do to your SIEM is stop receiving from it.

Q: Have you tested Prisma AIRS, Cisco AI Defense or Lakera against this?
A: No. Every strength attributed to those products here is their vendor’s own public material, untested, and there has been no witnessed bake-off. Nor should the absence of a capability from this page be read as its absence from a vendor’s product. What is available instead is a thirty-day evaluation so your security team, or a third party you commission, can read, run and attack the software on your own deployment. Publication rights are narrower than the testing right: benchmark results with no pre-approval provided the version and configuration are named, security findings after coordinated disclosure. All under a licence still pending counsel.
