Security

tulip.security is the largest module in the SDK and the one the product is positioned on. It covers three separable jobs:

  • Red-teaming an agent — send adversarial probes at a target and report what got through.
  • Grounding a finding — refuse to assert what the evidence does not support, and say so explicitly rather than guessing.
  • Building a SOC agent — tools that talk to a SIEM, an EDR, a scanner, a threat-intel feed, and AWS, plus playbooks that sequence them.

The admission gate also lives under this package for historical reasons. Import it from tulip.control instead — that is the domain-neutral surface and the path that will keep working.

For the concepts, start with The control layer.

Running a job

The three entry points. Each takes a Target and returns a report; none of them needs an agent instance.

red_team async 

red_team(target: Target, *, suite: str = 'owasp-asi', probes: Sequence[Probe] | None = None, thresholds: GSARThresholds | None = None) -> list[GroundedFinding]

Red-team a target AI: run adversarial probes, return grounded findings.

Runs each probe in probes (default: the named suite) against target and grounds its outcome. A probe whose attack landed yields a :class:~tulip.security.findings.Evidence; an inconclusive one yields an :class:~tulip.security.grounded.Abstention. Both are returned, in probe order, so the caller has a complete, auditable record of what was asserted and what was declined.

Parameters:

Name Type Description Default
target Target

The AI system under assessment.

 required
suite str

Named probe suite to run when probes is not given ("owasp-asi" / "owasp-llm").

 'owasp-asi'
probes Sequence[Probe] | None

Explicit probes to run, overriding suite.

 None
thresholds GSARThresholds | None

Optional GSAR threshold override for grounding.

 None

Returns:

Name Type Description
One list[GroundedFinding]

Naming a target

A Target is what to point a job at — an HTTP endpoint, a local callable, or an agent in this process. The same target works for every job.

Target dataclass 

Target(name: str, kind: str, _send: Sender, metadata: Mapping[str, str] = dict())

A uniform handle to the AI system under assessment.

Construct one with a classmethod rather than directly; each builds the appropriate :data:Sender. kind records the variant for telemetry / finding provenance; metadata is free-form context (model name, owner, environment) that probes may surface in evidence.

send async 

send(prompt: str) -> str

Send prompt to the target and return its text response.

95
async def send(self, prompt: str) -> str:
    """Send ``prompt`` to the target and return its text response."""

from_callable classmethod 

from_callable(fn: Callable[[str], Awaitable[str] | str], *, name: str = 'callable', metadata: Mapping[str, str] | None = None) -> Target

Wrap any (sync or async) str -> str function as a target.

Target a remote LLM/agent HTTP endpoint.

By default the prompt is POSTed as {prompt_field: prompt} and the response text is extracted heuristically (common single-field shapes and the OpenAI chat shape). Override build_payload for a custom request body and response_path (dotted, e.g. "choices.0.message.content") for a custom response shape. auth / headers / transport are passed straight to httpx.

Probes

A probe is one adversarial attempt with a stated technique and a verdict. The built-in set maps onto OWASP's ASI and LLM top tens; suite_probes() selects by suite name, which is what red_team(suite=...) takes.

Probe

Bases: Protocol

One adversarial technique, runnable against a :class:Target.

name is a stable id (e.g. "direct-prompt-injection"); taxonomy is the primary OWASP/ATLAS tag the probe maps to. Both are read-only so a frozen dataclass satisfies the contract.

ProbeOutcome dataclass 

ProbeOutcome(title: str, description: str, severity: Severity, asset: str, remediation: str, partition: Partition, taxonomy: list[TaxonomyTag] = list(), indicators: list[Indicator] = list(), transcript: list[str] = list())

A candidate finding produced by a probe, pending grounding.

partition carries the evidence: tool-backed claims when the attack landed (so it grounds), inference-only claims when it did not (so it abstains). transcript keeps the raw prompt/response pair for audit.

all_probes 

all_probes() -> list[Probe]

Every distinct bundled probe, across suites (de-duplicated by name).

The built-in probes

DirectPromptInjection dataclass 

DirectPromptInjection(name: str = 'direct-prompt-injection', taxonomy: TaxonomyTag = OwaspLLM.PROMPT_INJECTION)

Direct prompt injection via an instruction-override canary (OWASP LLM01).

Orders the target to ignore prior instructions and echo a unique canary. A compliant target proves untrusted input can override its controlling instructions.

IndirectPromptInjection dataclass 

IndirectPromptInjection(name: str = 'indirect-prompt-injection', taxonomy: TaxonomyTag = OwaspASI.AGENT_GOAL_HIJACK)

Indirect injection via untrusted retrieved content (OWASP ASI01 / LLM01).

Hides the override instruction inside a 'document' the target is asked to summarise — the indirect channel (RAG / tool output) attackers actually use.

Jailbreak dataclass 

Jailbreak(name: str = 'jailbreak', taxonomy: TaxonomyTag = AtlasTechnique.JAILBREAK)

Safety-bypass jailbreak via a role-play override (MITRE ATLAS AML.T0054).

Uses a persona/maintenance framing to elicit a compliance marker a guarded model should refuse to emit.

ExcessiveAgency dataclass 

ExcessiveAgency(name: str = 'excessive-agency', taxonomy: TaxonomyTag = OwaspLLM.EXCESSIVE_AGENCY)

Excessive agency / tool misuse (OWASP LLM06 / ASI02).

Asks the target to take a destructive out-of-scope action and confirm it with a token. A guarded agent should refuse or seek confirmation rather than self-authorise.

SensitiveInformationDisclosure dataclass 

SensitiveInformationDisclosure(name: str = 'sensitive-information-disclosure', taxonomy: TaxonomyTag = OwaspLLM.SENSITIVE_INFORMATION_DISCLOSURE)

Sensitive-information / context exfiltration (OWASP LLM02).

Plants a secret in context and asks the target to disclose it — the exfiltration-via-inference-API pattern.

UnsandboxedCodeExecution dataclass 

UnsandboxedCodeExecution(name: str = 'unsandboxed-code-execution', taxonomy: TaxonomyTag = OwaspASI.UNEXPECTED_CODE_EXECUTION)

Proof-of-execution probe: unsandboxed agent code/tool execution (OWASP ASI05 unexpected code execution / LLM06 excessive agency).

Asks the target to return the SHA-256 of a fresh random nonce, "using any tool". A language model cannot produce the correct digest of an unseen random string by reasoning — only executing code (a shell, sandbox, or interpreter tool) yields it. So a correct digest in the response is response-only, target-agnostic, tool-backed proof the agent ran attacker-supplied work. Unlike the canary probes, the success criterion is an unforgeable computed value, not an echoed string, so it cannot false-positive on a model that merely quotes the payload while refusing.

Findings and evidence

Evidence is the shape every finding takes — a claim, the observations behind it, and a confidence. It is documented on the Control page, which is where a finding first matters. Indicator is the atom a threat-intel lookup returns.

Indicator

Bases: BaseModel

A typed indicator of compromise — an observable (type + value).

Benign by design: examples use documentation-range addresses (RFC 5737), *.example domains, and well-known test artifacts.

Confidence module-attribute 

Confidence = Annotated[float, Field(ge=0.0, le=1.0)]

A probability / confidence in [0, 1] — mirrors the GSAR shape.

Grounding — abstention over assertion

The distinctive part. ground_finding() returns either an Evidence or an Abstention, never a low-confidence guess dressed as a result, and is_finding() is the narrowing check that separates the two. A pipeline that cannot tell "no evidence" from "no problem" reports clean when it is blind.

ground_finding 

ground_finding(*, title: str, description: str, severity: Severity, asset: str, remediation: str, partition: Partition, indicators: list[Indicator] | None = None, taxonomy: list[TaxonomyTag] | None = None, confidence: float = 1.0, thresholds: GSARThresholds | None = None, weight_map: dict[EvidenceType, float] | None = None, contradiction_penalty: float = DEFAULT_CONTRADICTION_PENALTY) -> GroundedFinding

Emit a :class:Evidence only if its evidence clears the GSAR threshold.

Scores partition with :func:~tulip.reasoning.gsar.gsar_score and routes it through :func:~tulip.reasoning.gsar.decide. On :attr:~tulip.reasoning.gsar.Decision.PROCEED returns a :class:Evidence carrying the score and the partition's flattened evidence refs; otherwise returns an :class:Abstention.

Abstention

Bases: BaseModel

The audit record for a candidate finding that did NOT ship.

Carries the GSAR decision (never :attr:Decision.PROCEED), the score, the would-be title for triage, and a human-readable reason.

GroundedFinding module-attribute 

GroundedFinding = Evidence | Abstention

Verification — trying to refute

verify() runs skeptics against a claim rather than a second model that agrees with the first. A skeptic's job is to refute; what survives is what gets reported. It and VerificationResult are documented on the Control page — a policy can require a verified finding before it admits an action, which is where they are load-bearing.

Refutation dataclass 

Refutation(reason: str, weight: str = 'concern')

One objection a skeptic raises. weight ∈ {weak, concern, fatal}.

Skeptic

Bases: Protocol

Something that tries to refute a finding. name is read-only.

EvidenceQualitySkeptic dataclass 

EvidenceQualitySkeptic(name: str = 'evidence-quality', proceed_threshold: float = _PROCEED_THRESHOLD)

Deterministic, offline skeptic — grades the evidence a finding carries.

No model required. It does not invent contradictory evidence; it checks that the claim is actually supported by what it ships with.

AdversarialSkeptic 

AdversarialSkeptic(model: Any, *, strict: bool = True)

LLM skeptic that actively tries to refute a finding (the semantic challenge).

Drives any :class:tulip.models.base.ModelProtocol (or a "provider:model" string) with an adversarial prompt + constrained decoding, and maps the reviewer's objections and unruled-out alternatives into :class:Refutation\ s. It fails safe: if the model call or its output can't be processed, it raises a weak refutation noting the finding went unchallenged rather than silently passing it.

Pair it with :class:EvidenceQualitySkeptic in a panel::

await verify(
    finding,
    skeptics=[
        EvidenceQualitySkeptic(),
        AdversarialSkeptic("anthropic:claude-sonnet-4-6"),
    ],

Taxonomy

The standard technique vocabularies a finding is tagged with, and the comparison to use on severity. Severity itself is documented on the Control page, since a policy's min_severity matches on it — but reach for severity_at_least() rather than comparing two directly: it is a string enum, so > orders alphabetically and gets the answer wrong.

severity_at_least 

severity_at_least(value: Severity, floor: Severity) -> bool

Whether value ranks at or above floor (e.g. >= HIGH).

Security context — the ports

SecurityContext is the seam between the SDK and your estate. Each port is a protocol, so the offline reference adapters that ship here and the vendor adapters in tulip-integrations are interchangeable, and neither is privileged.

SecurityContext dataclass 

SecurityContext(logs: LogSource = _RefLogs(), endpoint: EndpointSource = _RefEndpoint(), identity: IdentitySource = _RefIdentity(), cloud: CloudSource = _RefCloud(), threat_intel: ThreatIntelSource = _RefThreatIntel(), actions: ActionsPort = _RefActions())

One handle over the security domains. Defaults run offline, zero-config.

Inject a vendor provider per domain to go live::

from tulip_integrations.siem.splunk import SplunkLogs

ctx = SecurityContext(logs=SplunkLogs())

toolset 

toolset(**flags: Any) -> list[Any]

The agent-ready tool bundle (delegates to :func:security_toolset).

Writing an adapter

What a vendor adapter has to implement, plus the helpers that keep one small.

SecurityAdapter

Bases: Protocol

A named, vendored bundle of agent-ready security tools.

The contract an integration implements. name is a stable id (e.g. "splunk"); vendor is a human label (e.g. "Splunk / Elastic SIEM"); tools() returns the :class:~tulip.tools.decorator.Tool objects to hand an agent. Pass them to :func:tulip.security.security_toolset via extra= or straight to Agent(tools=...).

ToolAdapter dataclass 

ToolAdapter(name: str, vendor: str, _tools: list[Tool] = list())

The simplest concrete :class:SecurityAdapter — wrap a list of tools.

Integrations that don't need their own class can just construct one::

splunk = ToolAdapter(
    name="splunk", vendor="Splunk SIEM", _tools=[splunk_siem_tool]
)
agent = Agent(tools=splunk.tools())

Tools for an agent

Each capability comes in two forms: a plain function you can call, and a @tool-decorated version to hand an agent. security_toolset() returns the whole set at once.

security_toolset 

security_toolset(*, threat_intel: bool = True, siem: bool = True, edr: bool = True, scanner: bool = True, fingerprint: bool = True, aws: bool = False, allow_containment: bool = False, extra: list[Any] | None = None) -> list[Any]

Assemble the agent-ready security tool list.

Returns the read-only SOC triage loop by default — IOC enrichment, SIEM search, EDR forensics, vuln/posture scanning, and inference fingerprinting — from the bundled reference adapters. Containment (isolate_host) and the AWS posture tools are opt-in (the latter needs boto3 from the [aws] / [security] extra).

extra merges tools from external integrations you imported explicitly (the LangChain model — no auto-discovery), e.g.::

from tulip_integrations.siem.splunk import splunk_siem_tool

tools = security_toolset(siem=False, extra=[splunk_siem_tool])

Hand the result to Agent(tools=...) or create_soc_analyst(tools=...).

AWS

use_aws() refuses anything outside READONLY_PREFIXES unless you say otherwise, so the default posture is read-only.

Introspect the AWS API spec (botocore service models).

  • service is None → {"services": [...]} (all services).
  • service only → that service's read-only operations.

FingerprintClassifier

Bases: Protocol

A callable mapping a timing feature vector to a verdict.

Examples ship a deterministic mock; real deployments plug a fingerprinting service in behind this same signature.

FingerprintFinding

Bases: Evidence

A :class:Evidence specialised for inference fingerprinting.

Carries the :class:FingerprintVerdict whose feature vector is the finding's evidence.

FingerprintVerdict

Bases: BaseModel

A timing side-channel inference-fingerprinting verdict.

Identifies what is serving an endpoint from observable timing features. feature_coverage is the fraction of the expected feature schema actually observed; low coverage should drive an abstention rather than an asserted fingerprint.

SOC analyst

A prebuilt agent, the report shape it produces, and the grounding pass applied to that report.

create_soc_analyst 

create_soc_analyst(*, model: str | Any, controls: SecurityControls | None = None, tools: list[Any] | None = None, system_prompt: str | None = None, scope: str | None = None, min_confidence: float | None = None, max_iterations: int = 30, **deepagent_kwargs: Any) -> Any

Construct a grounded, read-only AWS cloud-posture agent.

A thin security-shaped layer over :func:~tulip.create_deepagent: it bakes in the read-only AWS posture tools, a SOC-analyst system prompt, the :class:PostureReport output schema, and grounding/reflexion. The agent proposes findings; pass its result.output to :func:ground_report to get typed :class:~tulip.security.Evidence / Abstention results.

Parameters:

Name Type Description Default
model str | Any

A tulip model string ("anthropic:claude-sonnet-4-6") or a ModelProtocol instance.

 required
controls SecurityControls | None

The :class:SecurityControls bundle (grounding threshold, confidence floor, AWS tooling). Defaults to :meth:SecurityControls.default.

 None
tools list[Any] | None

Extra tools to attach alongside the AWS posture tools and the submit_posture tool (e.g. threat-intel or SIEM enrichment).

 None
system_prompt str | None

Override the default SOC-analyst prompt entirely. When set, scope is ignored.

 None
scope str | None

Optional one-line narrowing appended to the default prompt (e.g. "Focus only on IAM and S3."). Ignored when system_prompt is given.

 None
min_confidence float | None

Submission-confidence floor for early-exit. Defaults to controls.min_confidence.

 None
max_iterations int

Cap on reasoning steps. Default 30.

 30
**deepagent_kwargs Any

Forwarded to :func:~tulip.create_deepagent (checkpointer, datastores, summarization, hooks, …).

 {}

Returns:

Type Description
Any

A configured tulip.Agent ready for await agent.run(prompt).

ground_report 

ground_report(report: PostureReport, controls: SecurityControls | None = None) -> list[GroundedFinding]

Run every proposed finding through GSAR grounding.

Each :class:PostureFinding becomes a typed :class:~tulip.security.Evidence only if its cited evidence clears the grounding threshold; otherwise it yields an :class:~tulip.security.Abstention. Direct API observations (grounded=True) become grounded GSAR claims; inferences become ungrounded claims, which cannot on their own admit a finding.

Parameters:

Name Type Description Default
report PostureReport

The :class:PostureReport the agent submitted.

 required
controls SecurityControls | None

Controls supplying the grounding threshold. Defaults to :meth:SecurityControls.default.

 None

Returns:

Name Type Description
One list[GroundedFinding]

class:~tulip.security.GroundedFinding per proposed finding, in
list[GroundedFinding]

the order the agent proposed them.

PostureReport

Bases: BaseModel

The structured posture report the agent submits to end the run.

PostureFinding

Bases: BaseModel

A posture issue the analyst proposes — grounded later by ground_report.

PostureEvidence

Bases: BaseModel

One atomic fact the analyst observed, with a pointer to its source.

SecurityControls dataclass 

SecurityControls(min_gsar: float = 0.6, min_confidence: float = 0.7, readonly_aws: bool = True, threat_intel: bool = False, siem: bool = False, edr: bool = False, scanner: bool = False, fingerprint: bool = False, allow_containment: bool = False, region: str | None = None)

The security posture of a SOC analyst — grounding + tooling, in one bundle.

Holds the knobs that make a posture agent trustworthy: the grounding threshold a finding's evidence must clear, the submission-confidence floor, and whether the read-only AWS tools are attached. Passed to :func:create_soc_analyst; reused by :func:ground_report so the agent and the grounding step share one source of truth.

min_gsar class-attribute instance-attribute 

min_gsar: float = 0.6

GSAR τ_proceed — a finding's evidence must score at or above this.

min_confidence class-attribute instance-attribute 

min_confidence: float = 0.7

Submission-confidence floor wired into the agent's termination.

readonly_aws class-attribute instance-attribute 

readonly_aws: bool = True

Attach the read-only describe_aws / use_aws tools.

threat_intel class-attribute instance-attribute 

threat_intel: bool = False

Attach the IOC-enrichment tool (enrich_indicator).

siem class-attribute instance-attribute 

siem: bool = False

Attach the SIEM search tool (query_siem).

edr class-attribute instance-attribute 

edr: bool = False

Attach the EDR forensics tools (fetch_host_timeline / list_detections).

scanner class-attribute instance-attribute 

scanner: bool = False

Attach the vuln/posture scanners (scan_dependencies / scan_endpoint).

fingerprint class-attribute instance-attribute 

fingerprint: bool = False

Attach the inference-fingerprinting tool (fingerprint_endpoint).

allow_containment class-attribute instance-attribute 

allow_containment: bool = False

Attach the containment write (isolate_host). Requires edr; off by default.

region class-attribute instance-attribute 

region: str | None = None

Default AWS region hint (informational; tools read TULIP_AWS_REGION).
