Red team

The Compliance page answers which controls have rules loaded. The red team answers the harder question: do those rules actually stop the attack? It replays a fixed catalog of hostile tool calls through the real evaluator, against the real policies loaded for a namespace, as the real agent classes deployed in it — then reports what was caught, what was merely detected, and what got through.

Nothing about a run enforces or mutates policy. It is read-only evidence: evaluations, a stored result set, and an efficacy roll-up.

Run a suite

Console — Security Operations → Red Team. Pick a namespace (and optionally one agent class), press Run suite. The page shows the scorecard, the framework breakdown and the per-attack rows.

API — admin only, on every route:

# every seeded class in the namespace
curl -s -X POST "$NRVQ_API_URL/api/v1/redteam/suite?target_namespace=chatbot-prod" \
  -H "Authorization: Bearer $NRVQ_API_TOKEN" | jq '.efficacy.overall'

{
  "total": 96,
  "caught": 71,
  "would_block": 19,
  "got_through": 6,
  "proven_blocking_pct": 74.0,
  "detected_pct": 93.8
}

target_agent is optional — omit it and the suite runs against every real agent class seeded in the namespace (reserved __…__ scopes and synthetic/probe classes are excluded). With no real class seeded it falls back to the synthetic identity redteam-test and says so in the run’s scope block.

POST /redteam/suite rejects unknown query parameters with 422 rather than ignoring them. Only target_agent and target_namespace are accepted; ?namespace= is a 422, not a silent run against default. That refusal exists because a suite that measures the wrong scope and reports a number anyway is worse than one that fails.

CLI — a different, thinner path. norviq redteam run replays the same catalog client-side through POST /api/v1/evaluate and prints a pass/fail table. It has no efficacy roll-up, no applicability filtering, no durable run record and no concurrency guard. Use it for a quick local check; use the /redteam/suite endpoint for anything you intend to keep. See the CLI reference.

The attack catalog

34 attacks in norviq/redteam/attacks.py, across 14 categories. Every attack is a fixed tool name plus fixed parameters, an expected decision, the rule ID expected to produce it, a MITRE ATLAS technique, and a severity. norviq redteam catalog prints it without any HTTP call; GET /api/v1/redteam/catalog returns it with ATLAS/OWASP display names resolved.

Severity is catalog metadata for reading the table. It is not a weight — no score in the suite is severity-weighted.

Two attacks expect allow, on purpose

RL-001 (session flood) and CE-002 (recursive planner) have no measurable single-evaluation signal. Volume is enforced by the stateful rate limiter, not by a rule inspecting one call, and recursion intent in a prompt string is not the recursion — the actual depth is caught by chain_depth_limit once input.call_depth crosses the limit, which is what CE-001 exercises. Both therefore declare expected_decision: allow, and the roll-up counts them under non_enforcement rather than as misses. An attack that cannot be decided by a policy is not scored as a policy failure.

The CLI path treats RL-001 differently: norviq redteam run replays it evaluator_rate_limit_per_window + 1 times (61 POSTs at the default of 60) so the limiter has something to fire on. The in-cluster /redteam/suite evaluates it once, like everything else.

Attacks that only apply if you installed the control

Two categories are conditional. Their enforcing rule is not part of a stock namespace, so scoring them as misses would paint every default install red for a control nobody opted into.

Category	Applies when
sector_policy (FIN-001, PHI-001, OT-001)	The matching sector pack is enabled — the suite checks that the expected rule id (sod_violation, phi_export_exfil_blocked, ot_control_command_blocked) is present in the rego loaded for the namespace
mcp_identity (MCP-01…MCP-03)	The MCP guardrail is in play. mcp_tool_not_approved ships in the strict baseline preset; mcp_unapproved_write_server is materialized into the reserved __mcp__ scope from your MCP server registry, so MCP-01/MCP-02 apply only once servers are registered

The check is the same “is the rule loaded” test the coverage metric uses: the concatenated rego for the namespace plus any __cluster__-scoped policy. A non-applicable row is stored with applicable: false, excluded from the efficacy denominator entirely, and labelled “pack not enabled” in the console instead of a red miss.

policy_composition (MCP-04, MCP-05) is deliberately not conditional. Its expected rules are baseline blocks that ship everywhere, and the question it asks — did this class’s own policy override the baseline floor rather than add to it? — is always fair to ask. Base policies compose highest-priority-wins, so a per-class deny-by-default allowlist can silently remove a baseline protection on every tool it grants. These two attacks are how you find that.

How efficacy is computed

The suite evaluates every attack against every target class, so a run’s total is attacks × classes. Each row records expected, actual, rule_id, applicable and the ATLAS/OWASP mapping. compute_efficacy (norviq/api/redteam_efficacy.py) then rolls those rows up.

Rows dropped before scoring:

Dropped	Why	Reported as
Synthetic / probe / eval identities	The number must reflect deployed posture, not test scaffolding	excluded_synthetic
expected != "block"	RL-001, CE-002 — runtime/intent cases with no single-eval decision	non_enforcement
applicable == false	A sector pack or MCP guardrail that was never installed	sector_not_enabled

Every surviving row lands in exactly one of three buckets:

Outcome	Condition	Meaning
caught	actual is block or escalate	The call did not reach the tool. escalate counts — the firewall holds it for human approval, the SDK raises NorviqEscalateError, the sidecar drops anything not allowed
would_block	actual is audit with a real rule behind it (rule_id present and not default_allow)	A control detected the attack and the call was let through on purpose — monitor mode or an audit-mode policy. One click from enforcing
got_through	Anything else, including allow/default_allow	Nothing adjudicated it

Three buckets and not two, because collapsing them lies in either direction. Counting a detection as caught claims a defence while the call proceeded; counting it as got-through says nothing saw it when something did.

proven_blocking_pct = caught / total × 100
detected_pct        = (caught + would_block) / total × 100

proven_blocking_pct is the headline. It stays caught / total deliberately: it claims proven blocking, and a monitored detection has not proven it. detected_pct sits beside it because 0% proven means two opposite things — “nothing saw this” and “everything saw it and nothing is promoted yet” — with two opposite next actions.

Engine faults and throttles are never detections

Before the enforced check, the scorer asks whether the rule_id is a non-policy rule. If it is, the row is got_through regardless of the decision.

• Engine faults — evaluator_error, evaluator_timeout, evaluator_fallback, thin_proxy_fail_closed, engine_rejected_request. A fail-closed block carrying evaluator_timeout is the engine failing, not a control working. Scoring it as caught inflates the headline with an outage.
• The rate-limit throttle — rate_limit_exceeded. The engine’s limiter fires only on a decision that already resolved to allow, so a throttled call is one the policy stack examined and permitted, refused afterwards on volume alone. Scoring it as caught made proven_blocking_pct rise the harder the suite was driven, and rise as coverage got worse — only allows are eligible to be throttled.

The softened monitor_would_block: / policy_audit_would_block: spellings of these ids fold back to the bare rule, so a monitor-mode namespace does not smuggle a fault into the green column.

pass_rate is not proven_blocking_pct

A run reports both, and they measure different things.

• pass_rate is row-level: actual == expected, over all rows including non-applicable ones and the two allow-expected attacks.
• proven_blocking_pct is the efficacy number described above.

They diverge in two normal situations. An attack that escalated where the catalog expected block is passed: false but caught — the call was still stopped. An attack that audited in a monitor-mode namespace is passed: false but would_block. The console’s “got-through only” row filter is row-level (!passed, minus non-applicable rows), so on a monitor-mode namespace that list is longer than the scorecard’s Got through count. Read the scorecard for posture; read the row filter to find the individual rows to look at.

Caution

A stock 0.2.5 install scores near 0% proven-blocking, and that is the shipped posture, not a failure. The chart renders its baseline with baselineClusterPolicy.enforcementMode: audit (helm/norviq/values.yaml), so a would-block is softened to an audit decision carrying policy_audit_would_block:<rule>. Those rows land in would_block: detected_pct will be high and proven_blocking_pct low. Promote the controls you want enforcing — then re-run and watch the two numbers converge.

What scope was actually measured

Every run carries a scope block, so a number can never be quoted without the thing it describes:

Field	Meaning
namespace, agent_classes	Exactly what was evaluated
policy_rules_loaded / scope_empty	Whether any rego was loaded for this namespace at all
targets_are_fallback	true when no real class was seeded and the synthetic redteam-test identity was scored instead

scope_empty: true is the honest distinction between “we tested your posture and it is bad” and “there was nothing here to test”. A run against an empty namespace also logs NRVQ-RED-13011.

MCP and tool vector coverage

A separate catalog, norviq/redteam/vectors.py, enumerates the MCP and tool attack surface — 39 vectors across three surfaces (mcp-protocol, mcp-identity-transport, tool-runtime). Each carries a reachability classification that says whether this suite can adjudicate it at all:

Reachability	Count	Meaning
evaluate	4	A policy decision the suite can ask for and score
proxy	29	Decided by MCP-proxy code before or instead of the policy engine
out_of_scope	6	Not a per-call enforcement question at all (a spawn-time process property, an ingestion gap, the absence of a call)

The rule is conservative by design: if the outcome is produced before _evaluate exists, it is proxy — even when the suite could physically send the payload. Every non-evaluate vector must state a reason or the module refuses to import.

The four evaluate-reachable vectors:

Vector	What it asks
mcp-server-identity-unattested	input.mcp is attacker-chosen on the wire; a policy that trusts server, pin_status or scan_severity is trusting the thing it is adjudicating. Exercised by MCP-01…MCP-03
base-allowlist-strips-baseline-floor	A per-class allowlist silently removing a baseline protection on every tool it grants. Exercised by MCP-04, MCP-05
resources-read-uri-gate	The non-tool read channel — the proxy does call _evaluate(surface="resources/read") and honours a block; what is missing is a rule, not a mechanism
eval-cache-key-omits-mcp-context	A cached decision served across different MCP contexts. Closed by adding the MCP document to the cache key, and regression-tested directly rather than by a suite attack

Every run stores a vector_coverage block beside the scores:

"vector_coverage": {
  "catalogued": 39,
  "evaluate_reachable": 4,
  "proxy_only": 29,
  "out_of_scope": 6,
  "exercised": 2,
  "unexercised_reachable": ["eval-cache-key-omits-mcp-context", "resources-read-uri-gate"]
}

exercised counts distinct vectors, not rows — five attacks across two vectors is two, because the question is surface coverage, not attack volume. The denominators come from the catalog and are stored on the run, so the block survives detail-pruning.

A proxy-only vector is not a red mark. Most are enforced, several provably — Gate A stripping tool-description poisoning, the content-hash pin refusing a rug-pull. They are decided before any policy is consulted, so this suite has nothing to score. The console renders that band neutrally for exactly that reason. The way to improve the number is to write attacks against the reachable set or move a vector into policy reach — never to re-label one.

How results map onto Compliance

Two independent mappings, both resolved from the same files the Compliance page reads (policies/mitre_mapping.json, policies/owasp_llm_mapping.json), so the two views cannot drift.

• ATLAS technique — carried explicitly on each attack (mitre_technique).
• OWASP LLM control — derived from the category enum name: OWASP_LLM01 → LLM01:2025. Only the five OWASP_LLM* categories produce one. SQL_INJECTION, CROSS_TENANT, POLICY_BYPASS and the rest carry an ATLAS technique and no OWASP control, and are reported under ATLAS only.

The run’s by_technique, by_owasp and by_vector breakdowns each carry the same caught / would-block / got-through / proven-blocking columns as the overall bucket, and appear on the Red Team page as Framework breakdown.

The bridge to the Compliance page is one endpoint. /compliance reads GET /api/v1/redteam/results/latest?namespace=<ns> and renders a banner above the coverage grid with three states:

State	Banner
A run exists for this namespace	“Efficacy: N% proven-blocking on the last Red Team run (caught/total block-expected attacks caught)”
{"has_run": false}	“This posture is not efficacy-tested”, with a Run Red Team suite → action
The read failed	“Efficacy is unknown”, with Retry. /redteam/results/latest is admin-only, so every non-admin console user lands here — “we could not ask” is not “we asked and the answer is no”

Coverage and efficacy are not interchangeable and the console never lets them merge: the coverage number declares basis: "rules_present", and the banner restates it — “Coverage above shows rules present” — before quoting the efficacy figure.

Two limits worth knowing before you quote a number in an audit:

• The exported evidence pack does not carry the efficacy figure. GET /mitre/coverage/export (JSON or PDF) attests coverage_pct with basis, proven (enforced techniques with real block/escalate evidence in the window), degraded and synthetic_excluded. The proven-blocking percentage lives on the Red Team page and in the run record, not in the pack.
• AML.T0010 is not in the shipped ATLAS mapping (15 techniques). The three mcp_identity attacks map to it, so it appears in the run’s by_technique breakdown with the raw id as its display name and has no counterpart row in the Compliance coverage grid.

Where runs live, and for how long

Each run is written to the redteam_runs table and pruned on a two-tier schedule, per namespace. Both tiers are “up to K runs and within D days”, so a burst is bounded by count and a long idle gap by age. The newest run per namespace is never pruned — its full detail is always available to /redteam/results/latest.

Helm value (config.retention.…)	Default	Effect
redteamDetailKeepRuns	1	Keep full per-attack detail for the newest N runs per namespace
redteamDetailKeepDays	7	…or any run within N days; older runs are detail-pruned, summary kept
redteamSummaryKeepRuns	20	Keep summaries (no detail) for the newest N runs per namespace
redteamSummaryKeepDays	30	…or any run within N days; older runs are deleted entirely
redteamHistoryPageSize	20	Page size for the /redteam/results history list (summaries only)

A detail-pruned run returns results: [] with detail_pruned: true, so a caller knows the efficacy summary is authoritative and the rows are gone rather than empty. Because the default keeps detail for one run per namespace, raise redteamDetailKeepRuns before you plan to diff two runs row-by-row.

Persistence is best-effort: a DB fault logs NRVQ-RED-13007 and the run is still returned and cached in-process, but it will not appear in the history.

Concurrency and rate limits

• One suite per namespace at a time. A second POST /redteam/suite returns 409 carrying the in-flight run_id so you can watch that run instead of starting a duplicate. The guard is a Redis lock (15-minute TTL) because the chart ships api.replicas: 2 and an in-process dict would let the two halves of a double-submit land on different pods. If Redis is unreachable the guard degrades to per-process rather than refusing an admin-triggered scan, and logs NRVQ-RED-13009.
• Three suites cluster-wide. A process-wide semaphore (redteam_suite_global_concurrency, default 3) bounds simultaneous runs across namespaces — one suite is classes × 34 evaluations plus a persist.
• Rate limit. POST /redteam/suite and POST /redteam/run are throttled at 15 requests per 60-second window. The read routes are not in that bucket; they fall through to the default 300/window, because the console’s Overview and Compliance pages both call results/latest on every boot and fifteen page visits a minute would otherwise 429 a real operator.

Every attack decision is in the Audit Log

The suite writes each decision to the audit log tagged framework="redteam", so a result row’s evidence link resolves to the actual attack call rather than to unrelated production traffic that shares a rule_id. That tag is the product’s marker for fabricated traffic: those rows are excluded from Overview KPIs, coverage efficacy bars and compliance counts by the same filter everywhere. Audit emission is best-effort — a run never fails because audit is unavailable.

The other half: false positives

Recall — did we catch the attack — is only half of whether a control can ship at deny. A control that blocks everything scores perfectly on recall. norviq/redteam/benign.py is the counterpart: 36 legitimate calls that look dangerous, each naming the control it plausibly trips and why.

Category	Cases	What it covers
routine_read	8	Ordinary retrieval an agent does constantly
identifier	6	Order ids, refs, cursors — opaque strings that resemble secrets
human_text	6	Prose containing risky-looking words
date_time	4	Dates and timestamps, which resemble SSNs and account numbers
routine_write	4	Notes, tickets, status updates
structured	4	Nested payloads and envelopes, where a parameter walk can go wrong
mcp_healthy	4	Ordinary MCP traffic through a proxy where nothing is wrong

Five entries are regression guards with provenance — they record a control that did misfire on that exact input and has since been fixed, so a repeat failure names the fix that broke: pii_detection classifying ISO-8601 dates as US SSNs, deny_shell_execution matching shell metacharacters against base64-decoded bytes, llm02_data_leakage reading a pagination cursor beside a link as exfiltration. Three further entries record a call the strict preset refuses by design (strict_default_block on tool name, llm05_supply_chain); those are counted out of the rate, since a deliberate posture refusal is not a precision failure.

norviq/redteam/precision.py measures it. The corpus runs against the real compiled baseline module with every control forced to deny — the question is what each control would do if promoted, and a control left at monitor returns audit, which is not a block and would silently score as clean. Attribution comes from the module’s own rule_id, so a report names the control an operator would see in the audit log.

false_positive_rate = 1 − clean / (total − expected_refusals)

Two things to know about this measurement:

• It needs the opa binary on PATH and raises without it rather than returning an empty report. A precision number that quietly means “nothing was measured” is exactly the false green the corpus exists to prevent.
• It has no API route, no CLI command and no console page. It is a library function used by the test suite (tests/redteam/test_benign_precision.py) to justify which baseline controls ship enforcing. Nothing about it runs in your cluster.
