Key Takeaways
- Sensitive Data Discovery Across Environments — According to Commvault, 99% of organizations have sensitive data sitting exposed right now. Commvault Cloud scans and classifies that data across structured, unstructured, cloud, and on-premises environments so you can see exactly what you need to protect.
- AI Security With Inline Prompt Redaction — Your AI models should never leak what they should not have access to. Satori-powered AI security intercepts prompts containing PII, salaries, and SSNs, then applies inline masking and redaction — maintaining productivity instead of blocking entire queries like traditional DLP tools.
- Unified Data Security for Users and AI — One policy governs who and what can access your data — whether it is a person or an AI model. You control sharing, manage retention, and remediate risk with least-privilege access enforced everywhere, from cloud to SaaS to on-premises.
- Real-Time Audit Logs for Compliance— Every interaction — user, dataset, policy applied, redactions — is captured in unified audit logs in near real time. You get the visibility you need to stay ahead of GDPR, HIPAA, and privacy regulations from a single platform.
About This Video
According to Commvault, 99% of organizations have sensitive data exposed right now, and AI makes discovering those gaps faster than any manual audit ever could. The convergence of cloud sprawl and AI adoption has created an urgent reality for CISOs and data security teams who need visibility they can act on.
Commvault Cloud walks you through how to discover, classify, and govern sensitive data across hybrid environments — whether structured or unstructured, cloud or on-premises. You will see how unified policy enforcement gives both users and AI models least-privilege access from a single control plane.
Satori-powered masking and redaction intercept sensitive data before it reaches AI models, monitoring every prompt and response in real time. This shifts your security posture from reactive controls to proactive governance — a critical move as AI workloads scale across your organization.
The regulatory landscape around GDPR, HIPAA, and emerging AI mandates demands unified audit trails and consistent data controls. Commvault Cloud provides centralized policy enforcement across structured and unstructured data, as well as AI prompts and access events, giving compliance, security, and IT leadership a single authoritative record covering live data, backups, and AI activity.

Frequently Asked Questions
How does Commvault find sensitive data?
Commvault scans and classifies sensitive data across structured, unstructured, cloud, and on-premises environments. You gain full visibility into where your risk lives and can act on it immediately from a single platform.
What is policy-aware prompt redaction?
Policy-aware prompt redaction uses Satori-powered inline masking to intercept sensitive data before AI models process it. Unlike traditional DLP that blocks entire prompts, this approach redacts only the sensitive elements so your teams stay productive.
How does Commvault prevent AI data leakage?
Commvault monitors AI prompts and responses in real time, detecting sensitive data before it leaves your environment. Inline redaction stops exposure at the point of interaction, giving you control without slowing down AI workflows.
What compliance standards does Commvault support?
Commvault Cloud helps support GDPR, HIPAA, and other privacy regulations through unified audit logs capturing user actions, dataset access, policy changes, and redaction in near real time. A single platform gives compliance and security teams visibility needed to demonstrate governance is operational, not just documented.
How does one policy govern users and AI models?
Commvault applies a single policy framework that enforces least-privilege access for both human users and AI models. You manage governance across clouds, SaaS, and AI workloads from one platform, eliminating gaps between separate tools.

Your organization runs on data. And so does AI. But here’s the problem: 99% of organizations have sensitive data that’s exposed, and AI can surface it instantly. PII. Health records. Financial data. Sitting where it shouldn’t be. Accessed by people and systems that shouldn’t have it.
Commvault gives you control. Our data and AI security capabilities are built for CISOs, Chief Data Officers, and the teams responsible for knowing what data exists and keeping it protected.
It starts with discovery. Commvault scans and classifies sensitive data across your entire environment — structured, unstructured, cloud, and on-premises. You see what you have. And where it’s exposed. Then you govern it. Apply access policies based on who or what is trying to use the data. Restrict sharing. Manage retention. Remediate risk.
And with AI changing how data gets used, Commvault goes further. It monitors AI prompts and responses for sensitive data so your models can’t inadvertently access or leak what they shouldn’t.
It’s not just about seeing your data. It’s about protecting and governing it more effectively. Commvault extends beyond protection by enabling policy-aware enforcement that governs AI prompt responses alongside data access — unifying capabilities that typically require separate tools. That’s the advantage. One simple unified policy that helps keep your organization compliant and AI safe without slowing innovation.
Imagine a common scenario. An employee uses an AI assistant to enhance their productivity. They input actual employee data into the chat, requesting that the model summarize performance and identify the top and bottom performers. While this may seem like a productivity boost, the prompt contains sensitive, regulated information such as salaries, social security numbers, and home addresses.
Before any data leaves the environment or is processed by the AI model, Commvault’s AI security, powered by Satori, intercepts it. The system automatically detects sensitive fields and applies inline masking and redaction, enforcing the same access governance policies defined earlier for our data stores.
Commvault, powered by Satori, offers a policy-aware prompt redaction feature that differs from tools that rely on data loss prevention or block entire prompts. This approach allows you to maintain productivity while helping to keep sensitive data under your control. Because redaction occurs before the model processes the data, it helps prevent sensitive information from influencing or contaminating the large language model’s dataset. This helps protect both your users and your AI environment.
The result is that the AI generates a meaningful summary that identifies your highest and lowest performers while protecting confidential details. This is how we make AI security practical. Governance that safeguards without disrupting how people work.
It’s audit week. The CISO and CIO are reviewing how internal users and AI assistants handle sensitive data. They need answers fast. Who accessed what? Were the masking policies applied correctly? Were any AI queries touching regulated fields?
Commvault’s AI security, powered by Satori, captures every interaction. The audit log records each query, including the user, dataset, applied policy, and redactions performed in near real time. Here, they can see a specific user prompt from the AI chat demo, including both the original and redacted versions, along with details like access level, rule creator, and execution time.
Unlike point tools that only handle backup activity or DSPM scans, Commvault offers unified audit visibility across live data, AI prompts, and governed access events, helping provide leadership with a single authoritative record. For the CISO, this means rapid compliance reviews. For the CIO, it helps provide proof that governance is operational, not just theoretical.
You understand your data. You control who uses it. And you can prove it. Data and AI security that helps comply with GDPR, HIPAA, and privacy regulations. That gives you confidence in your AI. That protects your data and keeps pace with your business. That’s Commvault.
With Commvault, you’re not just protecting AI, you’re transforming data security. Unified visibility allows you to view sensitive data across clouds, SaaS, and AI from a single platform. One policy for users and AI models enforces least-privilege access automatically everywhere. Dynamic masking, redaction, and policy-aware AI responses protect live data in motion, not just at rest. Unified audit trails quickly demonstrate compliance, helping transform oversight into confidence.
Security, IT, and compliance leaders can now shift from reactive controls to proactive governance, responsibly adopting AI, protecting sensitive data, and building a resilient data security posture for the future.
