This is the closest direct competitor on this site, and pretending otherwise would be useless to you. Straiker does not sit at a gateway watching AI traffic go by and call that agent security. They hook the same place we hook. Their own page for the Anthropic integration says it in one line: “Execution-path hooks stop the risky tool call before it fires.” (straiker.ai/anthropic-claude) Their product page says Defend AI “provides runtime security for coding agents including Cursor, GitHub Copilot, and Claude Code” and that it “detects and blocks destructive actions like file deletion and config changes, prevents data exfiltration of proprietary code and secrets, and identifies malicious MCP server and Skills connections in development environments.” (straiker.ai/products/defend-ai) Read that list. It is our list.
So the difference is not what gets stopped. It is where the decision gets made. MoorAI decides on the machine, from a local threat matrix, and emits category · risk · keyed one-way hash and nothing else. Straiker decides in a detection service. Their integration blog is explicit about the shape of it: “Route model traces or proxy logs to Straiker’s Detection Cloud.” (straiker.ai/blog, Nov 2025) That is not an accusation — it is the architecture their product needs, and it buys them things a local matrix cannot buy.
And “on-prem” does not close that gap the way the word suggests. Their on-prem installer is public, and we read it. It provisions EKS (--install-eks), and its inference chart serves Straiker’s own vLLM build against a model catalogue of seven profiles — antman, hulk, quicksilver, thor, thanos, vision, wanda — scheduled onto GPU node pools whose instance families default to ["g4dn","g5","g6e"], with p4d and p3 profiles alongside. (github.com/straiker-ai/onprem-installer, Apache-2.0) Self-hosted Straiker is a GPU Kubernetes cluster. It is a serious piece of engineering. It is not a laptop.
MoorAI is the laptop. A PreToolUse hook inside the coding agent and an MCP stdio gateway in front of the tool servers, evaluating a 67-entry threat matrix locally, blocking before execution, failing closed when the control plane is unreachable, and landing an ed25519-signed, content-free record of every decision. The agent is AGPL-3.0, so “no content leaves the device” is a claim you can check by reading the code rather than a sentence you have to trust.
Three things are deliberately absent from this page. (1) How their hooks work. “Execution-path hooks” is asserted on their marketing site with no public technical documentation behind it; whether that is a PreToolUse hook, a shell wrapper, an MCP shim or a local proxy, we do not know, and we are not going to guess in public. (2) Their accuracy numbers. Defend AI is marketed as “6-21x lower false positive rates than frontier model judges with 98.1% detection accuracy at <300ms latency”; no methodology, dataset or third-party validation is published, so those are vendor claims and appear here only as vendor claims. (3) Company facts. Funding round, founding year, headcount, headquarters and patents are reported inconsistently across sources we checked, so none of them appear at all. Every Straiker statement below is either a direct quote from their site or a line from a repository they publish, with the source named.
The wedge is where detection runs — and it is provable from artifacts they publish themselves, not inferred from marketing.
fail_open with a default of true, described as: “Unreachable Defend → allow and stamp x-straiker-verdict: fail-open-*.” The same README explains what that stamp means — “fail-open-* means traffic is flowing but inspection is degraded” — and its security section advises operators to “Alert on fail-open-* / webhook errors so a degraded control is visible.” (github.com/straiker-ai/kong, README) That is a defensible availability choice for a gateway, and they document it honestly. It is also the opposite of MoorAI’s: no control plane, no network, no problem — the local evaluation still runs, and if it cannot run, the action does not.get_raw_body() returns nil, and traffic is proxied uninspected — HTTP 200, x-straiker-verdict: fail-open-no-body.” On plugin composition: attach the buffered plugin to a route that also uses ai-proxy and “the buffered plugin silently stops enforcing while still returning 200 with x-straiker-verdict: allow.” (github.com/straiker-ai/kong, README) Publishing that is to their credit — most vendors would not. It is also the structural cost of enforcing in a proxy tier you have to configure correctly. A hook that runs in-process has fewer places to be misconfigured into silence.Their strongest argument against us, stated fairly and then answered. Straiker publishes a whitepaper titled “No Hard Boundaries: The Case for Semantic Detection in Agentic AI”, and its argument is that pattern matching and small classifiers are the wrong primitive against modern semantic attacks. Aimed at a 67-entry, largely deterministic threat matrix, that lands. It is true. A multi-turn, politely-phrased, role-played jailbreak will walk straight past a pattern, and we are not going to claim otherwise. The answer is architectural, not detective. MoorAI is not trying to detect the persuasion. It is standing at the point where the persuasion has to become an action. A PreToolUse hook sees rm -rf /, a read of ~/.aws/credentials, or an MCP call to a server that is not on the allow-list — and it sees the same thing regardless of how eloquently the model was talked into it. You do not have to detect the argument to block the act. That is a genuinely different bet from theirs, and where the act itself is ambiguous — a prompt going out, a document being summarised — their bet is the better one, and the second table below says so.
Almost every row here is the same property restated: the decision is computed where the action happens, with nothing sent anywhere to compute it. That is what makes offline enforcement, fail-closed behaviour, stdio MCP coverage and a content-free evidence trail possible at once — they are not four features, they are one architecture seen from four angles.

Thirteen rows, and they are not padding. This is the vendor against whom MoorAI loses the most, and trimming this section would be the single most dishonest thing this page could do. Straiker is building a security platform for all enterprise AI — the agents you buy, the agents you build, and the chatbot your customers talk to. MoorAI governs one surface: the coding agent on a developer’s machine. If the requirement is broader than that surface, the rows below are the answer and we are not the vendor.

These nine are the rows where a checkmark in each column would be technically accurate and completely uninformative. Both products genuinely do all nine. They do them from different positions, with different failure modes, and the difference is the whole reason you would pick one. Read the cells, not a mark.
| MoorAI does it by… | Straiker does it by… | |
|---|---|---|
| Claude Code coverage | A PreToolUse hook in the agent, evaluating locally and returning a decision before the tool runs. Nothing leaves to reach that decision. | “Execution-path hooks for Claude Code,” in their words, plus OpenTelemetry from Cowork and the Compliance API for Claude Platform and Enterprise. The hook mechanism is not publicly documented, so we describe it no further than they do. |
| Cursor and GitHub Copilot | Narrower, and we will say so. Full hook enforcement is on Claude Code today; Codex and Copilot CLI are detection-only. macOS and Windows. | Named as first-class: “runtime security for coding agents including Cursor, GitHub Copilot, and Claude Code.” Broader assistant coverage than ours, plainly. |
| Blocking destructive actions at runtime | At the tool call, in-process. The hook sees the command and its arguments and refuses. No network path is involved, so nothing about the block depends on reachability. | At their enforcement point, which varies by deployment mode — hook, sensor, proxy or gateway. Their published gateway plugin defaults to fail_open: true; the hook path’s failure behaviour is not documented. |
| Prompt injection, direct and indirect | Deterministic matching in the live flow — injected instructions arriving via tool output, a poisoned rules file, or a cross-server toxic flow — plus the backstop that the injection still has to become a tool call, which is separately governed. | Fine-tuned detection models reading traces and payloads, which is a genuinely stronger primitive for multi-turn and obfuscated attacks. Requires the trace to reach the detector. |
| MCP inventory and risk scoring | What this machine actually runs, including stdio servers with no network presence, scored locally and reported content-free as part of the AIBOM. | A vulnerability database at scale, built from research across the ecosystem — far more known-bad servers than any single endpoint could learn about on its own. |
| Skill and rules-file analysis | Drift detection on a fingerprint. The file is hashed and watched; the content of your CLAUDE.md is never transmitted. |
Identifying “malicious MCP server and Skills connections in development environments,” in their words — classification of what the file is trying to do. |
| Secrets and PII detection | Before it leaves. The prompt, paste or tool argument is checked on the device and blocked at the boundary; only category and a keyed hash are recorded. | By analysing the payload — “prevents data exfiltration of proprietary code and secrets.” Higher-fidelity classification, reached by the payload being analysed somewhere. |
| OWASP LLM Top 10, MITRE ATLAS, NIST AI RMF mapping | Attached to each signed decision, so the compliance artefact is the enforcement record itself — and it contains no prompt content. | Attached to findings and red-team results, across a much wider estate than one developer laptop, with SOC 2 and ISO 27001 behind the platform. |
| Agent discovery | Endpoint-out. Which agents, CLIs, browser tools and MCP servers exist on this machine — including the ones nobody registered and the ones that never open a socket. | Estate-in. Which AI applications and agents exist across the organisation, including ones running in cloud infrastructure where no laptop is involved at all. |
Where MoorAI is stronger. Nothing leaves, and it still works when nothing can. Every MoorAI verdict is computed by code you can read, on the machine where the action is about to happen, from a matrix that needs no GPU and no round-trip. That is what makes offline enforcement real, makes fail-closed the default rather than a flag, makes stdio MCP servers governable at all, and makes an audit trail an auditor can read without reading anybody’s prompts. If your constraint is a regulator, an air gap, or a legal team that will not approve conversation content leaving the endpoint, that constraint is the product.
Where Straiker is stronger. Everything except that. Seven fine-tuned detection models will catch semantic attacks a 67-entry matrix will not. Offensive red-teaming against your live agents is a capability we do not have and are not building. They cover the AI applications your company builds and the chatbot your customers use, neither of which runs on a developer laptop, and they meet enterprise procurement where it actually is — SOC 2, ISO 27001, analyst coverage, and a gateway story for infrastructure teams who will never install an endpoint agent. If your AI risk is broader than “coding agents on developer machines,” theirs is the larger product and this page is not going to pretend otherwise.
Use both, honestly. These two overlap more than any other pair on this site, and they still fail in different places. Run Straiker across the AI estate — the apps you build, the chatbots you expose, the gateways your traffic already crosses — and for adversarial testing of any of it. Run MoorAI on the developer machines, where the tool call has to be refused in-process rather than judged remotely, where stdio MCP servers never generate a trace to route anywhere, and where the evidence an auditor reads must contain no one’s prompt content at all. Their fail-open default and our fail-closed one are not a scandal; they are two reasonable answers to a question you should answer for yourself, per surface.
Straiker capabilities are mapped from Straiker’s own published material, checked in 2026: straiker.ai/products/defend-ai, straiker.ai/anthropic-claude, their integration-models blog, and the public repositories at github.com/straiker-ai — kong, apim, litellm, AgentGateway and onprem-installer. Every quoted phrase is theirs. The mechanism behind “execution-path hooks” is not publicly documented and is not characterised here. Straiker’s published accuracy, false-positive and latency figures are vendor claims with no methodology or independent validation available, and no row on this page depends on them. Funding, patents, founding year, headcount and headquarters are omitted because public sources disagree. ◐ = partial — present but narrower than the other column. — = unconfirmed, not necessarily absent. MoorAI marks reflect shipped capability: full hook enforcement is on Claude Code today with Codex and Copilot CLI detection-only, the agent runs on macOS and Windows, and MoorAI does not ship TLS inspection — it is permitted by the capability spec as an opt-in layer and no row here credits it. The community agent is AGPL-3.0 and uncapped; the console is free for an entire organisation up to 200 users.
