Privacy Code
Scanning

A privacy code scanner that helps engineering teams identify and stop privacy risks while code is being written, not after an app is already live and data is already flowing.

If your app uses AI, APIs, or third-party integrations, traditional privacy tools are already too late.

Automated Sensitive Data Flow Mapping and Visualization

Problem: Privacy Risks Start in Code - Not After Deployment

Traditional privacy tools detect problems too late, when data is already in motion,
pushing teams into remediation rather than prevention.

Sensitive Data in Logs & Local Storage

  • Sensitive data appearing in logs or local storage forces organizations into reactive cleanup.
  • DLP tools surface problems only after exposure, sending teams into weeks of tracing data paths, cleaning up logs, and rewriting code.
  • Incidents often start with simple oversights like printing full user objects or passing tainted variables into logging functions.
  • As applications scale and code paths multiply, these mistakes become harder to catch and more frequent.

Shadow AI & Third-Party Integrations

  • Data shared with third party or AI integrations must align with Data Processing Agreements and your privacy notice.
  • Silent code changes can redirect sensitive fields to analytics platforms, observability pipelines, or LLM prompts.
  • These hidden shifts erode user trust and increase regulatory exposure long before privacy teams are aware.

Hidden Cross-Service Flows

  • Sensitive data flows between microservices and APIs in ways teams cannot easily track or document.
  • Cross repo dependencies over REST, GraphQL, or gRPC and complex code transformations defeat traditional scanning approaches.
  • As a result, sensitive data exposed through these API protocols often goes undocumented or poorly understood, creating hidden privacy and compliance risk.

Sensitive Data in AI Prompts

  • AI usage is accelerating, increasing the risk of unintentionally sharing sensitive data with external models.
  • Many companies restrict AI services, yet scans routinely uncover AI SDKs like LangChain or LlamaIndex.
  • Current privacy tooling is either too reactive, discovering these flows after the fact, or completely blind to them.
  • Privacy teams scramble to understand what data is sent to AI systems and whether user notices and legal bases cover those flows.

Why Existing Tools Fail

Regulations like GDPR and US privacy frameworks require accurate data maps and reports such as RoPA, PIA, and DPIA. In fast moving engineering environments, those maps quickly fall out of date.

Most data privacy solutions fall into two buckets.

Governance, Risk, and Compliance Platforms

GRC platforms provide blank templates for RoPA, PIA, and DPIA, like this one from Vanta, and ask privacy teams to do the heavy lifting. This usually means interviewing application owners, manually reconstructing data flows, and updating reports, only to repeat the process every time systems change

Production focused Privacy Platforms

Traditional privacy platforms operate only after applications are live. They attempt to infer data flows from information already stored in production systems, which leads to partial automation and limited visibility. These tools also rely on predefined knowledge of third party services, leaving them blind to shadow AI and new third party integrations introduced directly in code

How Privacy Code Scanning Works

Detect and stop sensitive data exposure directly in your development workflow.

Scan Code as It’s Written

HoundDog.ai integrates directly into your development workflow to scan code in IDEs (VS Code, IntelliJ, Cursor) and in CI pipelines as it is written or generated.

Trace Sensitive Data Flows

The scanner maps how sensitive data moves through functions, APIs, third-party services, and AI integrations, revealing hidden exposure paths.

Enforce Privacy Rules Before Deployment

Apply allowlists to define which data types are permitted in LLM prompts and other risky sinks, and automatically block unsafe pull requests to maintain compliance.

Privacy Code Scanner for Sensitive Data Flow Detection in IDE and CI

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 Records of Processing Activities (RoPA), Privacy Impact Assessment (PIA), and Data Protection Impact Assessment (DPIA) pre-populated with detected data flows and privacy risks aligned with GDPR, CCPA, HIPAA, and other regulatory frameworks.
  • 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 modern engineering teams building AI-powered and privacy-critical applications.

Code-Level Data Flow Intelligence

Analyze real data paths across functions, services, and repositories instead of relying on keyword scanning or runtime guesses.

Built for AI & LLM Workloads

Detect and control what sensitive data is sent to prompts, embeddings, and external AI APIs before it ever leaves your environment.

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

Generate RoPA, PIA, and DPIA directly from detected code-level data movement, always up to date with system changes.

Why Shift-Left Privacy Matters

Stop privacy risks at the source — while code is being written, not after it reaches production.

AI Exposure Happens Fast

Sensitive data can be exposed to AI tools
within minutes of code changes.

Post-Production Tools Are Too Late

Fixing leaks after release
doesn’t prevent real damage.

Compliance Requires Prevention

Modern privacy programs must prevent risks,
not just report them after exposure.
