Your CASB Sees AI as Just Another SaaS App
Cloud Access Security Brokers manage access, enforce policies, and monitor cloud usage. But they treat ChatGPT the same as Salesforce — missing the entirely different risk profile of conversational AI.
The Challenge
Why CASBs Are Not Enough for AI Governance
CASBs were built to solve the shadow IT problem for SaaS applications — discovering unsanctioned cloud apps, enforcing access policies, and preventing data leakage through API-level controls. AI tools present a fundamentally different challenge. Unlike traditional SaaS where data flows through structured fields and APIs, AI interactions are freeform conversations where any data can be shared at any moment. A CASB can tell you that an employee logged into an AI tool and how long they used it. It cannot tell you they just pasted your product roadmap into the prompt.
- CASBs monitor SaaS at the API and session level — not the conversation level
- AI interactions are unstructured and conversational, unlike traditional SaaS data flows
- CASB inline controls (block, allow, coach) do not extend to prompt content
- Shadow AI discovery requires understanding AI-specific interaction patterns, not just SaaS discovery heuristics
Visibility Gaps
Where CASBs Fall Short with AI Tools
Access Without Content Awareness
CASBs control who can access an AI tool and from which device. But once access is granted, they have no visibility into what the employee shares with the AI model — the CASB's job is done at the door.
SaaS Policies Do Not Map to AI Risks
CASB policies are designed for structured SaaS actions: file uploads, sharing permissions, admin configuration changes. AI risk is about conversational content — something CASBs have no framework to evaluate.
Incomplete AI Tool Discovery
CASBs discover cloud apps through network traffic analysis and SSO logs. Many AI tools are accessed via browser extensions, CLI tools, IDE plugins, or embedded features in other apps — channels CASBs often miss.
No Model Output Monitoring
CASBs focus on data flowing into cloud apps. AI tools also generate data — code suggestions, document drafts, analysis results — that may contain hallucinated sensitive information or reproduce training data. CASBs do not monitor this output vector.

Oximy complements these platforms by adding the AI-aware content inspection layer they were not designed to provide.
Why Oximy
How Oximy Adds What CASBs Cannot
Your CASB governs cloud access. Oximy governs what happens inside AI conversations — the layer CASBs were never built for.
Conversation-Level Governance
Oximy operates at the conversation level, not the session level. It understands the content of every prompt, the context of every interaction, and the sensitivity of every piece of data shared.
AI-Native Data Classification
Purpose-built classifiers that detect sensitive data in natural language prompts — not just structured patterns. Oximy understands when an employee describes a customer situation, even without explicit PII fields.
Complete AI Tool Discovery
Oximy discovers AI usage across every access vector — browsers, IDE extensions, CLI tools, API integrations, and embedded AI features in existing SaaS apps. Not just the tools that route through your proxy.
AI-Specific Risk Scoring
Every AI interaction receives a risk score based on data sensitivity, tool risk profile, user context, and organizational policy. CASBs score cloud apps; Oximy scores AI interactions.
FAQs
Frequently asked questions
No. Your CASB remains essential for cloud access governance — SSO enforcement, conditional access, SaaS discovery, and cloud DLP. Oximy addresses a specific gap: the inability of CASBs to inspect and govern the content of AI interactions. The two solutions serve different but complementary purposes in your security architecture.
