Handling and securing sensitive data is a practice fraught with potential pitfalls such as inadvertent leaks, compliance violations, and the ever-present threat of cyberattacks.

Modern organizations must manage ever-growing data volumes while striving for regulatory compliance and protecting sensitive information. Traditional [data loss prevention](https://www.paloaltonetworks.com/cyberpedia/data-loss-prevention) (DLP) methods haven't kept pace with today's modern data landscape encompassing new data types, formats, and sources.

Legacy solutions can't deliver the diverse classification techniques needed to support modern data security outcomes, often leading to inaccurate identification of sensitive data, false positives, or missed data breaches. Traditional data classification methods rely on predefined patterns that lack the context needed to identify leaks accurately.

Enter Palo Alto Networks [Data Security](https://www.paloaltonetworks.com/sase/ai-powered-saas-and-data-security) with AI-powered discovery and classification, a game-changing solution revolutionizing how businesses discover, manage, and protect their data assets.

## **100+ Pretrained ML Classifiers Automate Discovery and Classification**

Palo Alto Networks Data Security provides 100+ Deep Neural Network (DNN) based classifiers out-of-the-box to automate data discovery and classification.

These models train on diverse data corpora encompassing a wide range of languages to interpret semantics with contextual understanding for near-perfect accuracy. DNN classifiers for documents or text data are available across financial, healthcare, legal, and source code categories. Image-based [machine learning](https://www.paloaltonetworks.com/cyberpedia/machine-learning-ml) (ML) classifiers are also available for categories such as driver's licenses, passports, and national IDs. Analyzing images without extracting or scanning their content allows organizations to detect and protect personal information efficiently.

At Palo Alto Networks, a dedicated team of data scientists has worked diligently over the past several years, researching new ways and techniques to improve DNN and ML models. We're proud to disclose that these efforts have come a long way, and we're now at the fifth generation of DNN models.

*Figure 1: Pretrained ML classifiers available as predefined document types*

## **AI and ML Augmentation Increase Detection Accuracy**

Pattern matching with only regular expressions and keywords can be prone to false positives. Our approach, however, augments these DLP data patterns with ML models.

These models then undergo training using diverse datasets, leveraging [large language models](https://www.paloaltonetworks.com/cyberpedia/large-language-models-llm) (LLMs) to establish ground truth. With these AI-powered improvements, we're seeing markedly accurate detections with more than a 90% reduction in potential false positives.

Today, over 250 out-of-the-box data patterns are augmented with ML and LLMs across personally identifiable information (PII), general data protection regulation (GDPR) requirements, financial, and other predefined categories.

Lastly, in the quest to deliver industry-leading accuracy for DLP detections, Palo Alto Networks has created a customer-driven feedback loop. Within the context of a data security incident, customers can report false positives for specific detections, along with its reasoning for context. This feedback loop and reporting mechanism allows us to analyze and re-train our ML models, leading to even higher accuracy.

## **Customer-Trainable AI Models Protect Unique Intellectual Property**

You almost assuredly put considerable time and resources behind protecting your organization's "crown jewels": data. Today, high-value data is considered digital currency, including trade secrets, financial projections, client lists, proprietary source code, and more.

Palo Alto Networks enables customers to train their own ML models with sample intellectual property (IP) to find exact matches or similar datasets based on custom thresholds. These models can be tuned and retrained to ensure high accuracy and expanded over time to cover new types of IP.
