Trace every third-party data flow in code, and catch DPA violations before data starts flowing.

Sensitive data exposures to third parties are rarely intentional. They happen as codebases grow. A developer prints a full user object, a tainted variable carries PII through a chain of transformations, and by the time anyone notices, the data has already been sent to a third party. HoundDog.ai traces every flow into every SDK, API, and AI integration directly in code, so Data Processing Agreement violations are caught at scan time, before any data leaves your application.

How it works

Discover, trace, and guard sensitive data flows to every third party.

HoundDog.ai works the way developers do: in the codebase, in the IDE, and in the pull request. It traces your applications' data flows as defined in the application code logic to track more than 100 sensitive data types (including PII, PHI, CHD and auth tokens) through intermediate transformations across files, functions, and procedures regardless of nesting depth, and flagging them when they reach a third-party sink, whether that is an analytics SDK, a CRM API, or an LLM prompt.

1

Discover every third-party and shadow integration

Uncover all third-party SDKs, APIs, and shadow integrations introduced by engineering teams, often without the knowledge or approval of privacy teams, directly in the codebase before they ship.

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.

Guard against DPA violations before production

Apply precise allowlists per third-party SDK or API to enforce each Data Processing Agreement at the code level, automatically blocking unsafe changes in pull requests that would send unpermitted data elements to a processor. Default allowlists ship out of the box for common processors. For example, Stripe's defaults already include bank card details and exclude SSNs, so the baseline is in place from day one and the privacy team only customizes where the DPA diverges. For continuous visibility into every third-party data flow more broadly, see third-party data flow monitoring.

Full data map

Automated data mapping for GDPR compliance.

Unlike GDPR compliance software that relies on questionnaires, HoundDog.ai builds the data map from code. PII detection covers more than 100 sensitive data types spanning PII, PHI, cardholder data, and authentication tokens, plus custom patterns for proprietary fields that standard scanners miss. Processing purposes are derived from actual application behavior, third-party recipients and AI endpoints are identified from real integration points in code, and the resulting data map holds up when a supervisory authority requests your records.

Customer trust

Build customer trust through transparent data handling.

  • Generate evidence based data maps that show where sensitive data is collected, processed, and shared, including through AI and third party integrations.
  • Auto generate audit ready Privacy Impact Assessments (PIA) and Data Protection Impact Assessments (DPIA) pre-populated with detected data flows and privacy risks, aligned with GDPR, CCPA, HIPAA, and other regulatory frameworks.
  • Keep your Org RoPA current with new data flows and subprocessors surfaced as suggested edits, with the privacy team reviewing and approving every change.
  • Give privacy teams continuous visibility into processing activities without surveys or manual discovery.
  • No production monitoring required. No retroactive cleanup. No guessing.

Key differentiators

What makes HoundDog.ai different.

Purpose built for privacy teams that need data processing agreements enforced from real data flows detected directly from source code, not surveys or assumptions.

Code-level data flow intelligence

Detect and map sensitive data flows directly from source code across APIs, services, and third party integrations without relying on surveys, spreadsheets, or privacy tools that miss hidden integrations and SDKs.

Built for AI & LLM workloads

Discover AI SDKs embedded in code and detect sensitive data flows to LLM prompts and external AI APIs before your apps go live.

Prevent risk before deployment

Catch privacy issues during development and code review, not after data has already been logged, shared, or leaked.

Compliance from real data flows

Automatically generate audit ready PIA and DPIA documentation, and keep your RoPA current through scanner suggested edits, all from detected code level data movement so compliance stays up to date as systems evolve.

Questions

DPA enforcement, answered.

What is a Data Processing Agreement (DPA)?
A Data Processing Agreement is a contract between a data controller and a data processor that defines exactly which categories of personal data may be shared, for what purpose, and under what safeguards. Most third-party vendors (analytics, observability, CRM, AI APIs) act as processors, and your DPA with each one sets the boundary on what your code is contractually allowed to send them.
How does HoundDog.ai catch DPA violations in code?
HoundDog.ai traces every sensitive data element across function calls, transformations, and SDK invocations to detect when data not permitted under a DPA reaches a third-party sink such as Datadog, Salesforce, OpenAI, or any other processor. It runs in the IDE, on pull requests, and in CI so violations are caught before code is merged.
Can HoundDog.ai enforce DPA boundaries per vendor?
Yes. You can define a per-vendor allowlist of permitted data elements that mirrors the DPA, and HoundDog.ai will block pull requests that try to send anything outside that allowlist. Different vendors can carry different allowlists, so Datadog can be limited to metadata while Salesforce is allowed contact fields but not SSN.
Does this cover AI integrations like OpenAI and Anthropic?
Yes. AI integrations are first-class third-party sinks. HoundDog.ai traces tainted variables flowing into prompt templates and LLM calls, so PII that ends up inside an OpenAI or Anthropic prompt is flagged the same way as PII written to an analytics SDK.
How is this different from a network proxy, API gateway, or DLP?
Proxies, gateways, and DLP act in transit or after the fact, once sensitive data is already moving. They cannot prevent a developer from collecting data that should never have been collected. HoundDog.ai works at the code layer before the data starts flowing, which is the only place to enforce true data minimization.
