How HoundDog.ai works

Two products on one deterministic engine.

HoundDog.ai ships two products on the same deterministic dataflow core. Both run static analysis on your code; each is tuned to a different audience and outcome.

Code-based dataflow context

Fast, deterministic analysis with centralized context.

Privacy: code-based GDPR data maps and RoPA evidence
The gap

Keeping processing activities in sync with the codebase fails today: surveys don't scale and produce stale or guessed answers, GRC platforms ship blank templates, and privacy platforms infer flows post-deployment, missing shadow AI and SDKs in code.

The cost

Stale evidence: documentation weeks or months behind the code, and reported processing activities that diverge from implementation with every release.

With HoundDog.ai

GDPR data mapping grounded in code-based evidence across logs, storage, APIs, third-party and AI SDKs, keeping your RoPA current at development speed so you prevent risks instead of reacting after the fact.

Full Sensitive Data Map

One deterministic map across every repo.

Every detected sensitive data flow rendered in one map: PII, PHI, cardholder data, and auth tokens traced from source to every sink, including logs, storage, APIs, third-party SDKs, and AI integrations. Built from code, not surveys.

How it works

Code-level visibility, from IDE to CI.

HoundDog.ai operates inside the development pipeline. Scans run locally. Your code never leaves your machine.

1

Scan code as it is written

Integrates with IDE plugins for VS Code, IntelliJ, and Cursor, and with CI pipelines. Analyzes source code to map sensitive data flows across logs, storage, APIs, third-party and AI integrations, including hidden or "Shadow" integrations.

The taint-flow static analysis detects sensitive data elements by variable, method, function, and field name, tracing them through intermediate transformations across files, functions, and procedures regardless of nesting depth, and flagging them when they reach a sink, whether it is a controlled sink like a database or a high-risk one like an LLM prompt.

Source code defines how application data flows into files, logs, databases, APIs, AI prompts, local storage, and third-party integrations

Trace sensitive data flows

Automated data flow mapping shows exactly which sensitive data elements reach each data sink per repository, from logs and AI services like OpenAI to third parties like Slack, Stripe, and Twilio, with every flow rated safe or risky.

  • More than 100 sensitive data types supported, spanning traditional PII per GDPR's definition, PHI per HIPAA's definition, CHD per PCI's definition, and auth tokens and secrets, which can pose a serious data breach risk when exposed in logs.
  • More than 1,000 integrations supported, including direct and indirect AI SDKs, many of which are embedded in code without an established Data Processing Agreement, and third-party integrations spanning monitoring, SIEM, sales and marketing, payment, and many other categories.

Surface suggested edits

New data flows and subprocessors become suggested edits in your Org RoPA, each traceable to the code that generated it.

For processing activities outside the scope of scanned applications, such as Support or Sales, a collaborative workflow lets you invite stakeholders to review and make suggestions, while the privacy team keeps track of all processing activities in one place with full historical tracking.

Enforce before deployment

Bake your privacy policies into the pipeline by customizing the types of data allowed per data sink and blocking unsafe data flows when they are introduced in pull requests as part of your CI pipeline. Default allowlists are available out of the box, incorporating the standard data types expected in Data Processing Agreements per data sink, e.g. Stripe's allowlist includes bank card details whereas Slack's does not.

For Privacy Teams

Code-based evidence for GDPR data maps, RoPA & privacy reviews.

At development speed. Prevent risks instead of documenting them after the fact, with privacy teams in control: the engine proposes, the DPO approves.

Discover

Every integration, straight from the code

All third-party and AI integrations detected directly in source code, including Shadow AI, whether the data flows through an SDK or API, with 1,000+ integrations covered out of the box.

HoundDog.ai discovers every third-party and AI integration directly from source code, including OpenAI, Anthropic, LangChain, Salesforce, Datadog, and HubSpot

HoundDog.ai follows sensitive data into every sink, including LLM prompts, third-party SDKs, logs, files, local storage, and many others
Trace

Follow sensitive data into every sink

Trace 100+ sensitive data types (PII, PHI, CHD, auth tokens) across code paths and into every data sink, including logs, storage, APIs, third-party, and AI integrations.


Verify & Suggest

RoPA that keeps itself current

Keep your RoPA updated as new categories of personal data and subprocessors are introduced, detected directly from source code.

Validate design-phase privacy reviews with code-based evidence before code is pushed to production.

HoundDog.ai keeps RoPA current by suggesting Org RoPA updates, verifying alignment with PIA, blocking risky data flows, and catching log leaks early
HoundDog.ai vs. reactive DLP

Flagged before exposure, not after the leak.

DLP reacts once sensitive data is already written. HoundDog.ai traces it into the log statement at scan time, before it ever executes.

EXAMPLE 1 Payment card data in a log statement
HoundDog.ai: caught at scan time
String msg = String.format(
  "%s charged %s %s to the %s %s held by %s",
  merchant.getName(), amount, currency,
  card.getType(), card.getLast4(),
  cardholder.getName());
log.warn(msg);
// cardholder + card data traced before it runs
✓ Flagged at scan time. Card data never reaches the log.
Reactive DLP: after the fact
WARN  Uber Eats charged 148.27 USD to
  the CREDIT VISA-4242
  held by Sarah Johnson
  ([email protected])
✗ Card data already written and committed.
EXAMPLE 2 Auth token in a debug log
HoundDog.ai: caught at scan time
log.debug("token refresh failed {}",
  provider, grantType,
  refreshToken, ex)
// secret traced before it runs
✓ Fixed in minutes. Nothing reaches the log.
Reactive DLP: after the fact
DEBUG token refresh failed
  provider=salesforce
  Refresh Token eyJhbGciOiJIUzI1

✗ Token already written. Remediation begins now.
