Security & Safety
That’s a real claim, and we don’t make it lightly. Every major frontier-model provider — Anthropic, OpenAI, Perplexity, xAI — publishes a public trust center, ships an enterprise-grade tier, and meets the certifications federal agencies, healthcare systems, and ISO-certified manufacturers require of their own infrastructure. This page covers what that buys you when you start running export-control data through any of them, why we recommend Claude for the actual compliance work, and the four guarantees ExChek adds on top.
The four trust centers
ExChek isn’t locked to one model. The plugin works inside any major frontier harness, so you inherit whichever provider’s security posture you already trust. Click through to read each provider’s scope letters, audit reports, and continuous-monitoring evidence yourself.
The shared bar
Different providers cover slightly different scopes, but the bar below is what most enterprise frontier tiers meet today. If your compliance team has a checklist of certifications they require before approving a new vendor, this is the list they’ll usually be holding.

Why we recommend Claude
Trust posture is table stakes — all four major providers ship enterprise-grade tiers. Where ExChek picks a side is narrower and more specific: agentic capability for enterprise workflows. Claude is currently ahead on the exact things a compliance agent has to do well — reading long technical documents, calling tools reliably, stringing multi-step reasoning together, and not making things up under pressure.
01
Claude Opus 4.7 hits 77.3% on MCP-Atlas (scaled tool use) and 78% on OSWorld-Verified (computer use) — both ahead of the field. Compliance work is tool-heavy: pull eCFR, screen CSL, generate Word, sign the audit log. Claude does that better than anything else right now.
02
Opus 4.7 leads on GraphWalks (long-context) and posts 80.6% on OfficeQA Pro — 23+ points ahead of the next model on document reasoning. CFR Part 774 is hundreds of pages. That’s the work.
03
Claude is the only frontier model trained from the ground up on a constitution — not prompted into safety after the fact. For high-stakes regulatory work, that means fewer surprises and reasoning that holds up under audit.

What ExChek promises you
Your frontier provider secures the model and the platform. ExChek makes sure the workflow stays yours, stays defensible, and never makes a decision you didn’t approve. Belt and suspenders.
Promise 1
Sensitive lookups — customer names, part specs, denied-party checks — happen on your machine, inside the frontier-model session you already control. We don’t copy your data to a server we run. If your IT lead asks “where does this go?” the answer is short: nowhere new.
Promise 2
The plugin doesn’t send us usage stats, error reports, or sample queries. We can’t see what parts you’re shipping or where. If you uninstall, we don’t even know that. The whole codebase is public — you (or your IT person) can read it.
Promise 3
Every classification, screening, and memo gets a sealed timestamp linked to the one before it. If anyone alters a record after the fact, the seal breaks — and the break is obvious. That’s the kind of paper trail BIS expects on the five-year recordkeeping rule.
Promise 4
ExChek never auto-files anything, never auto-approves a classification, and never puts the AI’s name on the memo. You read the reasoning, you check the citations, you sign off. If a regulator asks who made the call, you can answer with one name — yours.
What you actually get
You ship to Germany. A customer asks for a CCATS letter or an EAR99 self-classification. You run the request through ExChek. Three things happen automatically:
