Whose claims these are
The column describing another product paraphrases that vendor’s own published material, on a date printed at the top of each table. Nothing here has been independently tested, products in this category ship quickly, and a capability absent from a vendor’s documentation is not the same thing as a capability the product lacks. Every page links to the vendor’s own documentation so you can check what decides it for you.
AI security platforms and AI firewalls
Token Observe is not a complete AI security suite, and the product’s own strategy document forbids selling it as one. The category argument is the better page if you have not yet shortlisted a product.
Keycard
Keycard decides whether the agent gets a credential. Token Observe decides the call and then proves what the call actually did.
On agent authorisation itself, Keycard is the better purchase for most readers, and the roadmap says so before this page does
Palo Alto Prisma AIRS
Prisma AIRS decides whether the content is malicious. Token Observe decides whether the agent that sent it was allowed to.
On detection, on estate coverage, and on the assurance a procurement team can actually read — Prisma AIRS is the better purchase for most readers
Cisco AI Defense
AI Defense attaches a policy to an application’s connection and inspects what crosses it. Token Observe attaches permissions to an agent and decides what it may do.
For most readers shopping an AI security platform, Cisco AI Defense is the better purchase, and Token Observe’s roadmap says so before this page does
Zenity
Zenity gets into the path the agents are already on. Token Observe is the path the agents are pointed at.
On estate coverage and on assurance, Zenity is the better purchase for most readers, and the gap is not close
Noma Security
Noma decides from what the agent appears to be doing. Token Observe decides from what the agent was allowed to do, before anything is scored.
On coverage, on detection and on the assurance a procurement team asks for, Noma is the better purchase for most readers
Lakera
Lakera tells your application the content is an attack. Token Observe is the thing that refuses to send it.
On prompt-injection defence itself — the category this page sits in — Lakera is the better purchase, and it is not close
WitnessAI
WitnessAI stands in front of the interaction and classifies the intent. Token Observe stands in front of the API call and decides the action, its cost and its evidence.
On coverage of the estate and on detection quality, WitnessAI is the better purchase for most readers, and Token Observe’s own roadmap names it as a source to consume from rather than a rival
LLM gateways and AI proxies
Token Observe is a gateway in delivery. The gateway is how it arrives, not what it is for. The category argument is the better page if you have not yet shortlisted a product.
LiteLLM
If you already run LiteLLM, keep it. The question that decides whether you need anything more is about the actions your agents take, not about the proxy.
For most teams shopping for a gateway, LiteLLM is the better purchase, and it is not a close call
Portkey
Both hold the payload before it reaches a provider. One is built to carry it to more than 250 models; the other is built to refuse it and prove afterwards who said it could go.
For most teams shopping for an AI gateway, Portkey is the better purchase, and the reasons are not close
Kong AI Gateway
Kong governs the traffic. Token Observe governs the action. If you already run Kong, the first one is nearly free and the second one is the only reason to read further.
If Kong is already your data plane, Kong AI Gateway is the better purchase for most readers
Cloudflare AI Gateway
Cloudflare’s gateway decides what the payload contains. Token Observe decides whether the agent that sent it was allowed to.
For most teams putting a first control in front of model traffic, Cloudflare is the better purchase, and it is not close
Envoy AI Gateway
Both hold the request. One charges the token budget once the response completes; the other reserves the money before the request leaves your network.
For connectivity at scale on Kubernetes, Envoy AI Gateway is the better purchase, and it is free
MuleSoft AI Gateway
Both refuse the call inline. One refuses on behalf of an endpoint, the other on behalf of an agent that has an owner.
If you already run Anypoint Platform, MuleSoft is the better purchase and it is not close
LLM observability, tracing and evaluation
One refuses the call inline. The other scores it afterwards. Most estates need both, and they are not substitutes. The category argument is the better page if you have not yet shortlisted a product.
LangSmith
LangSmith’s callback handler watches the call from beside it, and their newer LLM Gateway now stands in it too. The remaining differences are narrower than they were, and worth stating precisely.
For the loop a developer actually works in, LangSmith is the right tool and Token Observe is not competing for it
Langfuse
Langfuse says in its own documentation that its SDKs are asynchronous and that blocking is a guardrail library’s job. That sentence is the whole comparison, and it is not a criticism.
For most teams shopping for LLM observability, Langfuse is the better purchase, and the certification gap alone decides it for many
Arize
Arize is instrumented into your application and reads what it did. Token Observe is a hop your agents call through and decides what they may do.
For the work an AI engineering team does every day, Arize is the right purchase, and it is not close
Datadog LLM Observability
Datadog puts LLM spans beside the rest of your telemetry. Token Observe puts a verdict in front of the call. Datadog also sells a verdict — and where it is made is the whole comparison.
If you already run Datadog, Datadog wins the observability half and it is not close
Braintrust
Braintrust is in the request path too. What it does there is deliver the call and record it; what it blocks is the release that would have made the call worse.
On evaluation, on assurance and on deployment maturity, Braintrust is ahead, and for most readers it is the right purchase
Cloud-provider native agent controls
If every agent, model and tool lives in one cloud, use that cloud’s controls. The argument here is for the estate that does not. The category argument is the better page if you have not yet shortlisted a product.
Amazon Bedrock AgentCore
AgentCore enforces Cedar at its own gateway boundary. Token Observe enforces one rule set across six providers from a process you run. The estate decides which you want.
If your agents, tools and targets are inside AWS, AgentCore is the better purchase and it is not close
Microsoft Entra Agent ID
Entra decides which identity the agent holds and whether it may be issued a token. Token Observe decides the individual call that token does not cover.
For agent identity itself, Entra Agent ID is the better purchase for most readers, and Token Observe’s roadmap concedes it in writing
Microsoft Agent 365
Agent 365 governs the agent as an identity in your tenant. Token Observe governs the payload that agent sends to a model provider.
For an organisation already on Microsoft 365, Agent 365 is the better purchase, and it is not close
ServiceNow AI Control Tower
AI Control Tower governs an AI asset through a lifecycle. Token Observe governs one request before it leaves your network.
If you already run ServiceNow, AI Control Tower is the better purchase, and the roadmap named ServiceNow before this page did
The category arguments
Six pages about what a whole class of product does and does not do. If you are still deciding which kind of thing you need, start there rather than here.
LLM gateways
Token Observe is a gateway in delivery. The gateway is how it arrives, not what it is for.
LLM observability
One refuses the call inline. The other scores it afterwards. Most estates need both, and they are not substitutes.
AI security platforms
Token Observe is not a complete AI security suite, and the product’s own strategy document forbids selling it as one.
cloud-native controls
If every agent, model and tool lives in one cloud, use that cloud’s controls. The argument here is for the estate that does not.
building it yourself
For a small estate, a few hundred lines of proxy is usually the right answer. The cost arrives later, and it arrives in specific places.
doing nothing
With three agents, no regulated data and no incident, doing nothing is often the correct decision. This page is about what changes it.
Tell us what is already in your stack.
Most of these comparisons end in running both, so the useful question is usually not which to buy but where the seam between them sits. Say what you already run and you will get a straight answer, including when the answer is that you do not need a second thing.
