Privacy  (1)

Data privacy is a major concern for organizations in every industry, thanks to frequent high-profile data breaches, new and pending data privacy laws, and an explosion in genAI (generative artificial intelligence) usage. While traditional data security strategies focus on preventing breaches from external hackers or disgruntled insiders, the popularity of genAI and other LLMs (large language models) has shifted the threat landscape.

As illustrated by a recent ChatGPT data leak, LLMs often train on personally identifiable information (PII) that’s either unintentionally scraped from the web or intentionally input by end-users who don’t understand the risks. Companies that build or operate AI models must remove sensitive information from training data and end-user prompts to remain compliant with new and existing privacy laws, but the volume, nature, and unpredictability of genAI training data sets make this a daunting task.

Luckily, tech innovators are rising to the challenge with a large, constantly evolving marketplace of data privacy tools to streamline, automate, and optimize privacy management. This guide compares the top data privacy tools for 2024 to help companies choose the right solution for their unique privacy challenges.

What do data privacy tools do?

Data privacy tools help companies streamline or automate privacy management and stay compliant with any applicable regulations. The most cutting-edge tools allow companies to efficiently manage privacy for extremely large-scale deployments, particularly for LLMs, artificial intelligence applications, and DSML (data science and machine learning) platforms. These tools work in concert with intrusion prevention solutions like network firewalls that protect private data from unauthorized outsiders, and security monitoring solutions like user and entity behavior analytics (UEBA) that prevent data exfiltration by compromised accounts or malicious insiders. As part of a comprehensive security tech stack, data privacy tools help streamline compliance and mitigate breach risks.

Different solutions can cover a wide range of features and solve a variety of AI data privacy challenges. Below is a list of the most common data privacy features, but many vendors offer additional capabilities that are described later.

Manage Privacy and Achieve Compliance

Data privacy feature Description
Sensitive data discovery, classification, and masking Scans AI training data to find sensitive information, classify the data appropriately, and mask personally identifiable information.
AI data visibility Monitors AI data inputs and outputs to identify problems and enable optimization.
AI firewall Protects LLMs and other AI models against attacks, harmful and unethical prompts, and unexpected model behavior.
Data encryption Makes sensitive data unreadable to unauthorized users without a decryption key.
Data loss prevention (DLP) Prevents unauthorized data transfers and, often, helps detect suspicious data movements from potential insider threats.
Data privacy/security posture management Analyzes information about the location of sensitive data, its security controls, who accesses it, and how it’s used to give companies an accurate data privacy and security assessment.
Data access governance Allows security teams to apply and enforce lead-privilege data access policies.
DSR and consent management Streamlines and/or automates Data Subject Request (DSR) processing and consumer opt-ins and opt-outs.
Risk prevention, detection, and remediation Detects vulnerabilities and other security risks; automatically prioritizes issues based on severity; and notifies remediation teams for accelerated response.
Data breach management Analyzes the impact of data breaches and provides logging and recommendations to streamline response efforts.

Granica

Granica is an AI infrastructure platform for building traditional and generative AI that is safe, effective, and low-cost. It is optimized for structured, semi-structured, and unstructured data in AWS and Google Cloud data lakes. Granica Screen offers real-time sensitive data discovery, classification, and masking for both data lakes and end-user LLM prompts. It also doesn’t sample the data it processes, reducing privacy and security risks. Other products include Granica Chronicle AI, a training data visibility service for data lake exploration and cost optimization, and Granica Crunch, a cloud cost optimization service that optimizes the compression of columnar files (such as Apache Parquet) in data lakehouses to lower the cost of storing and accessing large-scale data sets. Granica Screen uses high-efficiency, ML-powered scanning algorithms to process and safely unlock data for training and prompting at high accuracy and without driving up compute costs.
