AI-assisted coding and AI app generation platforms have sparked an unprecedented surge in software development. Enterprises are currently facing rapid growth in both the number of applications and the pace of change within applications. Security and privacy teams are under tremendous pressure as the surface area they must cover expands rapidly, even as staffing levels remain largely unchanged.
Existing data security and privacy solutions are too reactive for this new era. Many start with data already collected in production, but often it’s too late. These solutions often overlook hidden data flows to third parties and AI integrations, and for the data sinks they cover, they can help detect but not prevent risks. The question is whether many of these problems can be prevented early on. The answer is yes. Prevention is possible by building discovery and governance controls directly into development. HoundDog.ai offers a privacy code scanner built for exactly this purpose.
Data security and privacy issues that can be proactively addressed
Leaking sensitive data in logs remains one of the most common and costly problems
When sensitive data appears in logs, relying on DLP solutions can be reactive, unreliable, and time-consuming. Teams may spend weeks cleaning logs, identifying leaks across the systems that ingested them, and fixing code after the fact. These incidents often start with simple developer oversights, such as using tainted variables or printing out the entire user object in a debug function. When an engineering team has more than 20 developers, it becomes difficult to keep track of all code paths, and these oversights occur frequently.
Inaccurate or outdated data maps also pose considerable privacy risks
A core requirement under the GDPR and the US Privacy Framework is that processing activities must be documented, including details about the types of personal data collected, processed, stored and shared. Data maps will be incorporated into mandatory privacy reports such as Record of Processing Activities (RoPA), Privacy Impact Assessment (PIA), and Data Protection Impact Assessment (DPIA). These reports should document the legal basis for processing, demonstrate compliance with data minimization and retention principles, and ensure that data subjects can transparently exercise their rights. However, in a fast-changing environment, data maps can quickly become outdated. Traditional workflows for GRC tools require privacy teams to repeatedly interview application owners, a process that is time-consuming and error-prone. Important details are often overlooked, especially in companies with hundreds or thousands of code repositories. Operations-focused privacy platforms offer only partial automation as they attempt to infer data flows based on data already stored in operational systems. SDKs, abstractions, and integrations embedded in the code are often invisible. These blind spots can lead to violations of data processing agreements and inaccurate disclosures of privacy notices. These platforms only detect problems after data has already started flowing, so they don’t provide proactive controls to prevent dangerous behavior in the first place.
Another big challenge is extensive experimentation with AI within the codebase.
Many companies have policies that restrict AI services within their products. However, when scanning repositories, it is common to find AI-related SDKs such as LangChain and LlamaIndex in 5% to 10% of repositories. Privacy and security teams need to understand what data types are being sent to these AI systems and whether user notices and legal basis cover these flows. The use of AI itself is not the problem. This issue occurs when developers deploy AI without oversight. Without proactive technical enforcement, teams must retrospectively investigate and document these flows, which is time-consuming and often incomplete. As the number of AI integrations increases, so does the risk of non-compliance.
What is HoundDog.ai?
HoundDog.ai provides a privacy-focused static code scanner that continuously analyzes source code to document sensitive data flows across storage systems, AI integrations, and third-party services. Scanners identify privacy risks and sensitive data leaks early in development, before code is merged and before data is processed. The engine is built in memory-safe Rust and is lightweight and fast. Scan millions of lines of code in less than a minute. The scanner was recently integrated with Replit, an AI app generation platform used by 45 million creators, to provide visibility into privacy risks across the millions of applications generated by the platform.
Main features
AI governance and third-party risk management
Reliably identify AI and third-party integrations embedded in your code, including hidden libraries and abstractions often associated with shadow AI.
Proactively detect sensitive data leaks
Build privacy into every stage of development, from an IDE environment with extensions available in VS Code, IntelliJ, Cursor, and Eclipse to a CI pipeline that uses direct source code integration and automatically pushes CI configurations as direct commits or pull requests that require approval. Track over 100 types of sensitive data including Personally Identifiable Information (PII), Protected Health Information (PHI), Cardholder Data (CHD), and authentication tokens throughout their transformation into risky sinks such as LLM prompts, logs, files, local storage, and third-party SDKs.
Generating evidence for privacy compliance
Automatically generate evidence-based data maps that show how sensitive data is collected, processed, and shared. Create audit-ready records of processing activities (RoPAs), privacy impact assessments (PIA), and data protection impact assessments (DPIAs) pre-populated with detected data flows and privacy risks identified by the scanner.
why is this important
Companies need to eliminate blind spots
Privacy scanners that operate at the code level provide visibility into integrations and abstractions that are missed by operational tools. This includes hidden SDKs, third-party libraries, and AI frameworks that never show up in production scans until it’s too late.
Teams also need to discover privacy risks before they occur
Sensitive data in plaintext authentication tokens and logs, or unauthorized data sent to third-party integrations, must stop at the source. Prevention is the only reliable way to avoid incidents and compliance gaps.
Privacy teams need accurate and continuously updated data maps
Auto-generate RoPAs, PIAs, and DPIAs based on code evidence, ensuring documentation is created as you develop without repeated manual interviews or spreadsheet updates.
Comparison with other tools
Privacy and security engineering teams use a variety of tools, but each category has basic limitations.
General purpose static analysis tools offer custom rules but lack privacy considerations. They treat different types of sensitive data as equivalent and fail to understand modern AI-driven data flows. It relies on simple pattern matching, which generates noisy alerts and requires regular maintenance. There is also no built-in compliance reporting.
Once deployed, the privacy platform maps data flows based on information stored in operational systems. You can’t discover integrations or flows where data hasn’t yet been generated in these systems, and you can’t see abstractions hidden in the code. Because they operate post-deployment, they cannot prevent risks and create significant delays between problem occurrence and detection.
Reactive data loss prevention tools intervene only after data has been compromised. Lack of visibility into source code prevents identification of root cause. Once sensitive data reaches your logs or transmissions, cleanup will be slow. Teams often spend weeks remediating and reviewing vulnerabilities across many systems.
HoundDog.ai improves on these approaches by introducing a privacy-specific static analysis engine. Perform detailed inter-step analysis across files and functions to track sensitive data such as personally identifiable information (PII), protected health information (PHI), cardholder data (CHD), and authentication tokens. Understand transformations, sanitization logic, and control flow. Identify when data reaches risky sinks such as logs, files, local storage, third-party SDKs, and LLM prompts. Prioritize issues based on sensitivity and real risk, rather than simple patterns. Includes native support for over 100 sensitive data types and is customizable.
HoundDog.ai also detects direct and indirect AI integrations from source code. This identifies unsafe or unsanitized data flows into your prompts and allows your team to enforce allowlists that define the data types that can be used in your AI service. This proactive model blocks unsafe prompt construction before code is merged and provides enforcement that runtime filters cannot match.
HoundDog.ai goes beyond detection to automate the creation of privacy documents. Always have an up-to-date inventory of internal and external data flows, storage locations, and third-party dependencies. Actual evidence is input to generate audit-ready processing activity records and privacy impact assessments that comply with frameworks such as FedRAMP, DoD RMF, HIPAA, and NIST 800-53.
