Deterministic dataflow analysis, right from your codebase.

Two products on one engine. Privacy Code Scanner for proactive shift-left privacy and GDPR data mapping at dev speed. Dataflow Context Engine that maps every service, API, and field across monorepos and microservices, so AI coding agents run 5× faster and cheaper on average.

Code-based dataflow context

Fast, deterministic analysis with centralized context.

Engineering: cross-repo API and service context for your AI agents
The gap

API specs alone don't cover the services and fields consuming your APIs.

The cost

Without centralized dataflow context, agents burn tokens grepping repos and writing ad-hoc bash scripts to parse code relationships, often on code not even checked out locally, leaving AI with an incomplete picture.

With HoundDog.ai

An MCP server and Skills continuously fetch the exact cross-repo context, so prompting your agent to update a service or API runs 5× faster and cheaper, with the full picture.

Privacy Code Scanner

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.

Optional AI analysis layered on static findings auto-closes false positives, adjusts severities, and adds context. Scanning still runs locally on cheap CPU; AI only interprets traces the scanner already detected.


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

Dataflow Context Engine - for AI Coding Agents

Map every API dependency across your services for AI coding agents.

For engineering teams & AI coding agents. HoundDog.ai builds a full service catalog of every API, every field, and every downstream consumer across your repos. Local tools see one repo; the Context Engine sees the whole organization, so your AI coding agent changes a service or field knowing exactly what depends on it.

The business case

Cost of the gap vs. cost of closing it.

Cost of the gap
~100 hrs
per log-leak incident: scrubbing logs, auditing access, halting SIEM ingestion.
6,000+ hrs
a year on manual remediation at five leaks a month.
3 months
average documentation lag, a full quarter behind the code.
Value with HoundDog.ai
90%
less manual data-mapping effort (Fortune 500 outcome).
$2M
saved by one customer in eng hours and masking tooling.
< 5 min
to remediate a flagged exposure, fix suggested in the PR.
$200 / developer / year
Predictable per-developer pricing. No token meter, a fraction of a single remediation cycle, and it prevents the incident instead of cleaning it up.
