Safeguarding Sensitive Data in the Age of Generative AI: Harmonic Security’s Innovative Approach

In our increasingly digital world, the surge in generative AI tools presents a double-edged sword for organizations. While these tools offer remarkable opportunities for innovation and efficiency, they also elevate the stakes in data privacy and cybersecurity. With this in mind, a group of experts from Harmonic Security, including Bryan Woolgar-O’Neil, Jamie Cockrill, and Adrian Cunliffe, have developed a revolutionary AI governance and control layer designed to protect sensitive data as employees leverage these AI advancements.

The Challenge: Data Protection Amid Technological Upsurge

Organizations are grappling with the challenge of safeguarding sensitive data while adopting third-party generative AI tools. As these resources become increasingly embedded in day-to-day operations, the risks of exposing personally identifiable information (PII), source code, and payroll details have risen significantly. To counter this risk, Harmonic Security has developed a cutting-edge solution that ensures data security without hindering productivity.

Real-Time Detection of Data Leakage

Harmonic Security’s software tool stands out in its ability to identify data leakage types, effectively spotting sensitive information such as Employee PII, Employee Financial Information, and Source Code in real-time. This has empowered security teams to act swiftly and decisively, ensuring that sensitive data remains protected while innovation continues to thrive.

Integration with AWS for Enhanced Service Delivery

Further advancing their capabilities, Harmonic Security’s solution is now available on the AWS Marketplace, making it easier for organizations to deploy enterprise-grade data leakage protection seamlessly integrated with AWS services. This platform offers prompt visibility into generative AI usage and real-time coaching at the point of risk—crucial elements for maintaining secure and compliant data use.

The Technological Backbone: Optimizing Performance with AWS

Initially, Harmonic Security’s data leakage detection system operated with a detection latency of 1–2 seconds, which risked impacting user experience. To enhance performance, they partnered with the AWS Generative AI Innovation Center, setting four key optimization goals:

1. Reduce detection latency to under 500 milliseconds at the 95th percentile
2. Ensure detection accuracy across monitored data types
3. Support EU data residency compliance
4. Establish scalable architecture for production loads

Fine-Tuning Models for Low Latency and High Accuracy

The team employed Amazon SageMaker AI and Amazon Bedrock, alongside their proprietary ModernBERT model, to achieve low-latency data leakage detection. They implemented two classification approaches:

1. Binary Classification Model: Initially focused on detecting Mergers & Acquisitions (M&A) content, making it an effective first step in preventing sensitive data leaks.
2. Multi-Label Classification Model: Explored for future scalability, allowing the identification of multiple sensitive data types in a single passage, ultimately enhancing efficiency while managing resource demands.

Key Architectural Features

• Model Artifacts: Stored in Amazon S3
• Inference Code: Hosted in Amazon ECR using custom containers
• SageMaker Endpoint: Utilizing ml.g5.4xlarge instances for GPU-accelerated inference
• Monitoring: Continuous monitoring through Amazon CloudWatch, with automatic scaling based on demand

Generating Synthetic Data for Model Training

Utilizing Meta Llama 3.3 and Amazon Nova Pro, Harmonic Security tackled the challenge of scarce high-quality training data by generating synthetic examples for sensitive data categories, including M&A and financial information. Their framework incorporated advanced techniques for example selection and validation, ensuring a robust dataset for model fine-tuning.

Enhancing Model Performance

Harmonic Security leveraged advanced fine-tuning techniques for their ModernBERT models to achieve the desired performance improvements:

• Binary Classification: Achieved notable improvements in latency and accuracy.
• Multi-Label Classification: Demonstrated advantages in handling various sensitive information categories, paving the way for future advancements.

Results and Next Steps

The collaboration between Harmonic Security and AWS has yielded impressive results:

• Latency Reduction: From 1-2 seconds to under 500 milliseconds, achieving a remarkable 76% reduction at the median.
• Throughput Increase: An added capacity of 48%-640%, enhancing performance during peak usage.
• Accuracy Improvement: A +1.56% gain in accuracy for binary classification.

As Harmonic Security’s solution becomes available through AWS Marketplace, organizations can now adopt advanced AI-driven cybersecurity measures while maintaining strong data protection protocols.

Conclusion

With the rapid evolution of generative AI, organizations must prioritize data security without sacrificing productivity. Harmonic Security’s innovative approach exemplifies how tailored AI solutions can address pressing cybersecurity challenges, ensuring that both security and efficiency go hand in hand.

To learn more about harnessing AI for cybersecurity, consider the following next steps:
