gate-oc-audit vs SigmaShake

gate-oc-audit and SigmaShake are both guardrails & safety tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

gate-oc-audit

Gate operates as a drop-in proxy: your agent points at one endpoint, Gate inspects every outbound prompt and every inbound response, then enforces the policy you write — blocking injections, redacting secrets and PII, flagging ambiguous cases, and writing every decision to a tamper-evident audit log anchored to a blockchain. The vendor reports 97.4% F1 across 16 public prompt-injection benchmarks and a head-to-head F1 of 96.6% versus Lakera Guard's 83.7% on four matched datasets; methodology and per-benchmark scores are published. Token compression and prefix caching run on every request, and the vendor states users see 20% or more token savings without changing model outputs. Gate is in private beta with no self-hosted deployment option, so teams with hard data-residency requirements hit a wall immediately.

SigmaShake

SigmaShake intercepts tool calls from agents running in Claude Code, Cursor, VS Code Copilot, and Gemini CLI, evaluating each action against a rule set before it executes. The vendor states decisions resolve in roughly 85 ms using deterministic native evaluation — no model inference, no GPU, no token spend. Rules follow an Allow/Ask/Deny pattern, where Ask routes the action to a human approval queue rather than blunting everything with a hard block. The desktop app installs in about 30 seconds with no admin rights; the CLI drops into any shell or CI hook chain. Self-hosting is supported, which means the guardrail layer stays offline and never sends your code or commands to a third-party model.

Pros	Proxy-based architecture means your agent changes one endpoint, not its entire codebase, so you get injection defense without a rewrite and without touching model provider credentials. Bidirectional inspection catches both inbound injections from tool responses and outbound PII or credential leaks in model replies, which means a single misconfigured response cannot silently send a customer's SSN or an AWS key to the wrong place. Vendor-published benchmark methodology with per-dataset scores lets you audit the 97.4% F1 claim yourself rather than taking marketing copy on faith — which matters when you are deciding whether to put this in front of production traffic. Inline token compression and cache-prefix marking run automatically, so teams switching from direct API calls to Gate can offset the added infrastructure cost against token savings the vendor states average 20% or more per request. Policy-driven rule enforcement writes every block, redact, and flag decision to a tamper-evident audit log, so compliance reviews have a verifiable record of what the agent was told and what it said — without manual logging code in your agent.	Deterministic local evaluation at roughly 85 ms per check, so you avoid the latency and per-token cost of routing every agent action through a model-based policy guard. Ask mode holds a risky action in a human approval queue rather than blocking it outright, which means your agent keeps moving on safe tasks while you review the one call that needs a second look. PreToolUse hook integration for Claude Code and MCP server integration for Cursor, Codex, and VS Code Copilot, so the guardrail wires into agents your team is already running without a custom shim. Self-hosted deployment with no model inference, so your code, file paths, and shell commands never leave the machine — critical for teams with data-handling obligations. Per-user install with no admin or UAC rights required, which means individual developers can adopt it without waiting for IT to sign off on an organization-wide rollout.
Cons	No self-hosted deployment option exists on the current vendor page. Teams in healthcare, finance, or government with data-residency or network-isolation requirements cannot use Gate at all — they move to on-premise alternatives or build detection in-house. The 1% false-positive rate reported in the benchmark means Gate will block or flag legitimate requests. At low request volumes this is a minor inconvenience; in high-throughput pipelines where a blocked call means a failed agent task, teams need a human-review queue or a fallback path — neither of which is described in the current docs, adding implementation overhead. Private beta access is invite-only with no stated general availability timeline on the vendor page, so teams cannot schedule Gate into a production roadmap with confidence. Projects that need a committed SLA or guaranteed capacity move to established providers like Lakera Guard despite the lower reported benchmark scores.	No API is exposed, so teams building custom agent runtimes or embedding safety checks inside their own orchestration code cannot call SigmaShake programmatically — they wrap the CLI binary, which introduces a process boundary and complicates error handling at scale. The SHAKEDOWN benchmark that positions SigmaShake as the top-ranked guardrail was authored by SigmaShake, and competitor scores were modeled from public docs rather than measured runs; teams doing their own evaluation should run independent tests before treating the benchmark as a neutral comparison. Fleet management and team-level policy enforcement are paid-only features, which means a free-tier team cannot centrally audit what rules individual developers are running — a gap that matters the moment more than one engineer is using an AI coding agent on shared infrastructure. Windows support is the primary release target based on page emphasis and download prominence; macOS and Linux builds are listed but community reports on edge cases outside Windows are sparse, so teams running heterogeneous developer environments should validate on non-Windows machines before committing.

Bottom line

Gate-oc-audit is open source; only gate-oc-audit exposes a public API. Choose based on which difference matters most for your workflow.
