Straiker, measured.

Straiker red-teams your agents before they ship and blocks attacks against them once they run. This page scores that architecture across 16 capabilities against the same capabilities in Agen.co — with the sources, the scoring ladder, and the three rows Straiker wins all on the page.

The short answer

  • Straiker enforces at runtime, and the score says so. Every request, tool call and agent-to-agent handoff is inspected inline and blocked the instant it crosses a line, at a published sub-300ms. This is not posture work relabelled.
  • The verdict is about the attack. It answers whether an interaction is malicious — injection, exfiltration, tool abuse, hijacking. It does not answer whether the action was permitted, because nothing in the model holds who the action belongs to.
  • They win three rows of sixteen. Adversarial red teaming before an agent ships is the clearest: it runs continuously against the agent stack with build-pipeline hooks, and we do not offer it. They also take prompt-injection detection and marketplace reach.
  • Four rows are level, and they are load-bearing ones: audit records generated per decision, coverage of agents built on anybody's stack, and stopping regulated data leaving in an action.
  • No agent carries a named accountable human. The inventory records what an agent is connected to and what it can reach; an interactive session logs its initiating user. Agen issues a named owner per agent and attributes every individual action back to them, autonomous runs included.
  • The enforcement point is deliberately not the device. Coverage arrives through sensors, hooks, an extension and a gateway, with detection routed to their cloud — which is also why deployment model and data residency score the way they do.
The long read

What Straiker's verdict decides.

Two products can both render a verdict at the moment an agent acts and still be answering different questions. Straiker asks whether the interaction in front of it is an attack. That is a genuinely hard question, they answer it well, and it is not the same question as whether this agent was allowed to do this on behalf of that person.


Three modules over one detection engine

The product is organised as three modules mapped to the agent lifecycle, all served by the same detection engine. They are worth scoring separately, because a buyer evaluating runtime governance is often shown the red teaming.

  • Discovera continuous inventory of agents, the MCP servers, tools and skills they connect to, and what each one can reach. It runs posture assessment over that inventory — over-permissioned agents, risky integrations, misconfigurations — and covers builder platforms and coding agents alike, including agents nobody registered.
  • Ascendautomated adversarial testing. Purpose-built offensive models ingest the app's context, run reconnaissance across MCP servers, tools and infrastructure, then execute live attacks, with hooks into the build pipeline and findings mapped to the public control frameworks.
  • Defendruntime protection. It inspects every prompt, reasoning step and tool call, maintains state across a whole conversation, and blocks injection, exfiltration, tool manipulation and agent hijacking inline. A separate control takes a compromised agent fully offline: revoke its tools, freeze its memory, suspend the session, or halt a fleet.

Where Straiker is strongest

Three of the sixteen rows below go to Straiker and four more are level — the most either count has run on a comparison we publish. They follow from a real difference in where each product starts: theirs is the attack, ours is the action.

  • Adversarial testing before an agent shipsthis row goes to them outright and it is not close. Continuous automated red teaming against the agent's own tools, MCP servers and workflows, wired into the build pipeline so a prompt change or a new configuration triggers a fresh assessment. We govern agents once they are running; we do not attack them beforehand, and the table scores us accordingly.
  • Detecting the attack inside the contentdirect and indirect prompt injection, across text, code, images, audio and uploaded files, on detection models trained for the job rather than general-purpose judges. We govern the action a compromised agent attempts rather than inspecting the prompt that induced it. Both stop the same incident; only one of them reads the payload, and that row is theirs.
  • Where you can buy itboth modules are transactable through a major cloud marketplace against committed spend, and they hold a named partner designation with a frontier model provider. We are a focused platform rather than a marketplace presence, and that row is scored at a 2 for us on every comparison we publish.
  • Level, not lostfour rows come out even, and they matter. Audit evidence is generated per decision and streamed to the SIEM. Agents built on anyone's stack are covered, because Straiker builds no agents. And regulated data leaving inside an agent action is caught semantically, across connectors — a genuine strength of theirs that stands beside ours rather than below it.

A trace records a user. It does not carry an owner.

Every integration mode collects the same raw material: traces. An interactive session's trace names the user who started it, and that is real attribution as far as it goes. It goes as far as the session.

An accountable owner is a different object. It is durable, it belongs to the agent rather than to a session, and it survives the case that matters most — the long-running agent that acts at three in the morning with nobody in front of it. A trace of that run has a model, a tool chain and a result. There is no user in it to name, because there was no user. The published data model records what an agent is connected to and what it can reach; it does not record who answers for it.

This is why every row in the identity group goes one way while the runtime group is close. Accountability is not a stricter grade of logging. It is a different thing to hold, and it has to be held before the action, not reconstructed after it.

Malicious and permitted are different questions

Consider an agent that reads a customer record and posts it to an internal channel. Nothing is injected, no exfiltration signature fires, the tool call is well formed and the content is unremarkable. A threat verdict returns clean, correctly. The question that has not been asked is whether the person this agent acts for is entitled to that record.

Straiker does surface over-permissioned agents — that is posture work in the discovery module, assessed against the inventory and reported to a security team. It is the right control in the wrong tense for this case: it tells you the permission is too broad, some time after the action already used it.

Agen evaluates entitlement in the moment, against the human behind the agent, with five verdict types rather than allow and deny — including step-up authentication and a human approval step. Those two rows in the table are not scored against a missing feature; they are scored against a model that has no principal to evaluate.

Where the enforcement point sits

Five integration modes are documented, and the differences between them do real work in the table. An SDK exports traces from first-party agents. An eBPF sensor captures cloud and Kubernetes workloads with no instrumentation. A gateway mode routes requests through for evaluation, positioned for simpler applications. Those three are inline.

Two are not. Proxy mode ingests proxy logs for third-party SaaS, and the browser mode is documented as lightweight monitoring that collects input and output from web agents. That mix is exactly why the moment-of-action row scores a 4 rather than a 5, and why endpoint and browser enforcement score where they do: the architecture explicitly ships no thick client, and the enforcement point is a sensor, a hook or a gateway rather than the device the work happens on.

Detection itself runs in their cloud. Traces and proxy logs are routed there for analysis, which is a sound design and a real constraint for a buyer with residency requirements. No self-hosted or in-region detection option is published, which is the whole of the deployment row.

What is not published

Seven of the rows we score were dropped rather than published, because no primary source supports them in either direction. Two of those are the pricing rows: there is no pricing page, no pricing unit and no tiers anywhere on the site, so the cost of governing a hundred agents cannot be modelled before a sales conversation. That is a normal enterprise motion and it is not a criticism — but it means a row that usually publishes on every comparison could not publish here.

One more row was dropped on fairness rather than evidence. Connector and tool breadth measures a broker, and Straiker brokers nothing — it observes the connectors an agent already has. Scoring that row would have measured our architecture rather than a capability theirs was built to have.

The scored comparison

Sixteen capabilities, scored side by side.

Runtime enforcement, identity and accountability, coverage, and what it costs to operate — each scored 0–5 on capability depth against vendor documentation, including the three rows Straiker wins.

What the table says

Both products act at runtime. Only one of them knows whose action it is.

The runtime group is close, and it should be. Straiker inspects every request and tool call and blocks inline in under 300ms; the gap on that row is the two integration modes that read logs rather than sit in the path. Read the four groups in order and the shape is clear: enforcement is close, coverage is close in places and level in others, and the identity group is not close at all.

That is not an accident of feature scope. A detection engine is built to reason about content and behaviour, and it does that well enough to tie us on data-loss protection and beat us on injection. Reasoning about entitlement requires an object it does not have: an agent identity with a named human behind it, evaluated at the moment of the action rather than assessed as posture afterwards.

The findings

Four groups, four boundaries.

One per group in the table above, each traceable to the rows beneath it.

01

The verdict is about the attack

Injection, exfiltration, tool manipulation and hijacking are caught inline and blocked the instant they happen, with fine-grained control over the actions that matter. What the verdict does not evaluate is entitlement — whether this agent, acting for this person, was permitted to do this. Guardrails are customisable within threat and safety classes, not written as arbitrary policy.

published verdict latency<300ms
policy scopethreat classes
02

Nothing in the trace owns the action

Traces span user, model, tool chain and agent-to-agent calls, so an interactive session carries the user who started it. No documented object assigns a named human who answers for an agent, and an autonomous run has no session user to log. Attribution ends where the session does, which is before the case that needs it most.

accountable owner per agentnone
autonomous run attributionno user
03

The enforcement point is not the device

By design: the architecture ships no thick client, no proxy and no infrastructure change. Coverage arrives through an SDK, an eBPF sensor, a gateway, a proxy-log feed and a browser extension. Three of those are inline; the proxy feed reads logs and the browser mode is documented as monitoring. Discovery of unapproved agents, by contrast, is a real strength and scores a 4.

Priced and hosted on request

There is no pricing page, no published unit and no tiers, so both pricing rows were dropped rather than guessed — the only comparison we publish where the pricing row could not be scored at all. Detection runs in the vendor's cloud with no self-hosted or in-region option published, which is a live question for a buyer with residency requirements.

Watch it happen

Every action resolved to the human who answers for it.

Not the user who happened to open the session, and not a trace reconstructed afterwards — a named accountable owner carried on every agent, and every individual action attributed back to them, including the agents that run with nobody watching.

What closes the gap

Keep the red team. Add the layer that knows whose action it is.

Nothing about testing your agents adversarially or catching an injection in a document conflicts with governing the action itself. Agen adds what the trace cannot carry: every agent discovered without being routed anywhere first, a named accountable human behind each one, and every action judged against your policy at the moment it happens — internal agents and the ones facing your customers, on the same plane.

Methodology

How these scores were reached.

Sixteen capabilities publish from a worksheet of thirty-seven scored rows, on one 0–5 ladder applied to both columns. Seven rows were dropped rather than guessed: both pricing rows, because no pricing unit, tier or rate is published anywhere; delegated access and identity-provider compatibility, unsourced in either direction; new-integration SLA, unpublished; our own audit-first rollout row, held pending internal confirmation; and connector breadth, dropped on fairness because Straiker brokers no connectors. Ties and the rows Straiker wins are printed rather than filtered.

FAQ

Questions, answered.

What is Straiker?
It is an agentic AI security product organised as three modules over one detection engine. Discover builds a continuous inventory of agents, MCP servers, tools and skills, and runs posture assessment over it to surface over-permissioned agents, risky integrations and misconfigurations. Ascend runs automated adversarial testing — offensive models that ingest the application's context, run reconnaissance across its MCP servers and infrastructure, then execute live attacks, with hooks into the build pipeline. Defend provides runtime protection, inspecting every prompt, reasoning step and tool call to block prompt injection, data exfiltration, tool manipulation and agent hijacking.
Does Straiker block agent actions at runtime?
Yes, and it is worth being unambiguous about it: this is real runtime enforcement, not posture work relabelled. Every request, tool call and agent-to-agent handoff is inspected, with fine-grained controls that block remote code execution, data exfiltration, destructive commands, system file access and connections to high-risk MCP servers the instant they happen — at a published sub-300ms, with every decision traced to the SIEM. A separate control takes a compromised agent fully offline. The bound is which paths are inline: of five documented integration modes, the SDK, sensor and gateway sit in the path, while proxy mode ingests logs and the browser mode is documented as monitoring.
Where does Straiker score better than Agen.co?
Three rows of sixteen outright, and four more are level. Adversarial testing before an agent ships is the clearest: continuous automated red teaming against the agent's tools, MCP servers and workflows, wired into the build pipeline. We do not offer that, and we score a 1 on the row. Prompt-injection and content-threat detection, on models purpose-trained for it and covering text, code, images, audio and file uploads. And ecosystem reach, on the strength of cloud-marketplace availability and a frontier-model partner designation. Level with us on audit records per decision, on covering agents built on any stack, on data-loss protection, and on first-party depth inside the productivity suite, where neither of us lives inside the suite we govern.
How does Straiker identify the human behind an agent?
Through the trace, for as long as the trace lasts. Traces span user, model, tool chain and agent-to-agent calls, so an interactive session carries the user who initiated it, and behaviour analytics flag unusual usage patterns across the workforce. What the published model does not describe is a named human accountable for each agent as a durable property of that agent, or an individual action attributed back to that person. The distinction shows up hardest on autonomous agents: a long-running agent acting overnight produces a trace with no session user in it to name.
How is Straiker priced?
It is not published. There is no pricing page, no pricing unit and no tiers anywhere on the site, and every commercial path is a demo request or a free risk assessment. Both modules are separately transactable through a major cloud marketplace, which lets a buyer draw the spend against an existing cloud commitment, but no rate is listed there either. This is a normal enterprise motion, and it is why the two pricing rows were dropped from this comparison rather than guessed. Agen is priced per governed agent with no prerequisite tier.
Can Agen.co run alongside Straiker?
Yes, and given how little the two overlap it is the natural shape. Straiker keeps red-teaming your agents before they ship and catching the attacks aimed at them once they run — neither of which we do the way they do. Agen governs the action from a layer that holds identity: every agent discovered agentlessly across five surfaces, a named accountable human behind each one, and every action judged against your policy in under 30ms with five verdict types including step-up authentication and human approval. Nothing you already run has to be removed.
What is the difference between detecting a threat and governing an action?
A threat verdict asks whether an interaction is malicious. A governance verdict asks whether it was permitted. The two diverge on ordinary work: an agent that reads a customer record and posts it to an internal channel triggers no injection signature and shows no exfiltration pattern, so a threat verdict correctly returns clean — while the question of whether the person that agent acts for was entitled to that record has not been asked. Both controls are worth having. Only one of them can answer to an auditor who wants to know who authorised a specific action.
How current is this comparison?
It is scored against vendor public documentation and re-scored on a schedule we hold ourselves to. Every published row is backed by at least one primary vendor source, all of which are listed on this page — so any row can be checked against the vendor's own docs rather than taken on trust. Where a row could not be sourced in either direction, it was dropped rather than guessed, and this page says which ones and why.
