NVIDIA Flare (Federated Learning Application Runtime Environment) is an open-source, domain-agnostic SDK that enables secure privacy protection during the federated learning (FL) process. This allows organizations to train and fine-tune LLMs and GenAI applications without centralizing sensitive data, which helps to address challenges related to data privacy and regulatory compliance.
In traditional machine learning workflows, aggregating data from multiple sources can introduce privacy concerns, legal restrictions, and logistical complexities. FLARE provides a solution to these challenges by enabling clients to train models directly on their own datasets without sharing raw data. NVIDIA Flare works with PyTorch, TensorFlow, XGBoost, and other popular machine learning frameworks, as well as federated learning algorithms including FedAvg, FedProx, and FedOpt.

Netskope addresses concerns associated with shadow AI through its SkopeAI suite, which delivers extensive visibility and management capabilities over AI activities within an organization. The system monitors AI application user interactions and differentiates between personal and corporate instances to enforce granular policies according to user behavior and data sensitivity.
To protect sensitive data from being inadvertently shared with or used to train public or private LLMs, Netskope employs advanced data loss prevention (DLP) and data security posture management (DSPM) tools. These tools automatically discover, classify, and label data across various storage environments, enabling organizations to set policies that prevent confidential information from being exposed through AI interactions.
Key Features:
The Nightfall AI DLP platform provides robust protection for sensitive data across cloud applications, endpoints, and GenAI tools. The system acts as a trust boundary, protecting both corporate data and customer information during the development and deployment of AI models.
One of Nightfall AI’s core capabilities is its ability to detect and prevent the exposure of sensitive data, such as personally identifiable information (PII), payment card information (PCI), and protected health information (PHI). It addresses risks associated with data exposure, privacy breaches, and prompt-based attacks that can result in accidental data leaks or AI behavior manipulation.
Key Features:
Cyberhaven provides organizations with tools enhanced visibility and control measures to manage and secure their data exchanges with AI applications. It can detect and manage shadow AI usage when employees operate AI tools without the IT department’s knowledge.

This helps prevent sensitive data from being input into unapproved AI tools and tracks the origin of AI-generated content to mitigate the risks associated with malicious or inaccurate outputs.
Key Features:
Symmetry analyzes the risks associated with GenAI deployments, particularly in environments like OneDrive, SharePoint, and Microsoft Teams. The platform ensures that sensitive data is identified and monitored before it can be accessed or embedded by AI models, which helps to prevent data leaks.
The platform also focuses on preserving organizational compliance and ethical standards. By continuously monitoring user access to information through GenAI, Symmetry helps enforce regulatory requirements and uphold ethical standards.
Key Features:
Protecting LLMs and GenAI applications requires solutions beyond conventional security measures. These systems behave differently—they’re dynamic, probabilistic, and often unpredictable. Choosing the right security tools starts with mapping out the threat surface and identifying solutions purpose-built to address it.
Start by identifying your system’s exposure points. Security measures should begin by pinpointing exposure areas, including model endpoints, training pipelines, inference APIs, and the data they consume. Choose security tools that perform active stress tests on each system layer, rather than just monitoring them.
Red teaming capabilities specifically designed for LLMs are essential. Red teaming tools must be able to simulate prompt injection attacks, data leakage issues, and jailbreak scenarios in a controlled, repeatable way.
Next, prioritize visibility. Real-time telemetry should map user behavior, model responses, and detect any atypical patterns. The goal is to observe attacks during their active progression, rather than retrospective logging. Security solutions must work with current SIEM, SOAR, and EDR systems without requiring significant customization.
Look for AI security companies offering solutions that can detect subtle changes in model behavior. Adversarial inputs, poisoned training data, and malformed prompts can degrade performance or extract sensitive information. Defense tools need protective measures like input sanitization, response filtering, and output watermarking that can adapt to evolving threats.
Finally, make sure the solution supports both offensive and defensive measures. Red teams find the cracks, and blue teams fix them. The best tools enable you to handle offensive and defensive tasks quickly.
The AI threat landscape is evolving fast. Traditional tools weren’t built to handle model-level exploits, generative misuse, or runtime vulnerabilities in LLMs. Securing your GenAI systems and LLMs requires you to move beyond surface-level defenses, leveraging specialized tools that understand these systems’ operations and weaknesses.
Unlike static scanners or generic monitoring platforms, Mindgard’s Offensive Security solution is purpose-built for AI adversarial testing. It goes beyond compliance checklists to include emulating real-world attacks, stress-testing LLMs, and detecting runtime vulnerabilities that only appear during execution. With CI/CD integration and a model-agnostic engine, Mindgard embeds security directly into your AI pipeline, from development to deployment.

LLMs and GenAI systems face unique risks including prompt injection, data leakage, model inversion, training data poisoning, and adversarial inputs designed to manipulate outputs or extract confidential information.
Automated red teaming simulates real-world attacks on AI models—like prompt injection, evasion, and data extraction—to uncover vulnerabilities before adversaries exploit them. It enables continuous, scalable testing without relying solely on manual audits.
Federated learning enhances security and privacy by keeping raw training data decentralized. Instead of centralizing sensitive data, it shares model updates, reducing exposure risks and supporting compliance with data protection regulations.
AI security tools can be integrated into CI/CD workflows by embedding automated testing, red teaming, and monitoring steps. This allows real-time scanning for vulnerabilities and continuous model evaluation alongside regular software builds and updates. Solutions like Mindgard and ART offer CI/CD integration, enabling automated security testing during development, deployment, and production stages.
