data classification schema

sensitivity level definitions

integration with data pipeline

Limitations

requires predefined data classification rules

may reduce LLM context quality if over-filtering

cannot detect all sensitive data types automatically

output filtering and content restriction

Medium confidence

Filters and restricts LLM outputs based on user permissions and organizational policies, preventing unauthorized users from seeing sensitive information in model responses. Applies post-generation filtering rules to ensure outputs comply with access controls.

Solves for

Best for

enterprise security teams

compliance officers

multi-tenant LLM deployments

Requires

user permission definitions

output classification rules

content filtering policies

Limitations

cannot prevent all forms of information leakage through creative prompting

may require manual review of complex outputs

multi-user llm environment isolation

Medium confidence

Isolates data and interactions between different users and teams within a shared LLM deployment, ensuring that one user's data or queries don't leak to another user. Maintains separate data contexts and access boundaries across the organization.

Solves for

organizations with limited ML expertise

Requires

existing LLM deployment

API access to LLM

integration infrastructure

Limitations

requires API integration

may add latency to LLM responses

limited to control layer capabilities

sensitive data detection and classification

Medium confidence

Automatically detects and classifies sensitive data types (PII, financial data, health records, etc.) within inputs and outputs. Applies predefined or custom classification rules to identify what data requires protection.

Solves for

I need to automatically identify PII in user inputs before they reach the LLMI want to classify data sensitivity levels automaticallyI need to detect when sensitive data appears in LLM outputs

Best for

compliance-focused organizations

healthcare and financial institutions

data governance teams

Requires

data classification rules

sensitivity level definitions

training data for custom classifiers

Limitations

may have false positives/negatives

requires training on organization-specific data types

cannot detect all sensitive data without context

audit logging and access tracking

Medium confidence

Records comprehensive audit logs of all LLM interactions, including who accessed what data, when, and what results they received. Provides detailed tracking for compliance and security investigations.

Solves for

I need to track who accessed which data through the LLMI want to generate audit reports for compliance inspectionsI need to investigate potential security incidents or data breaches

Best for

compliance officers

security teams

regulated enterprises

Requires

logging infrastructure

log storage

audit analysis tools

Limitations

generates large volumes of log data

requires log storage and analysis infrastructure

doesn't prevent unauthorized access, only records it

hallucination prevention through data access control

Medium confidence

Reduces LLM hallucinations by restricting the model's access to only verified, authorized data sources. Prevents the model from generating false information by limiting its context to trustworthy data.

Solves for

I need to prevent the LLM from hallucinating about sensitive data it shouldn't knowI want to ensure the LLM only uses authorized data sourcesI need to reduce false information in regulated industries like healthcare

Best for

healthcare organizations

financial institutions

regulated enterprises

Requires

verified data sources

data access policies

source authentication

Limitations

doesn't eliminate all hallucinations

may reduce model capability if over-restricting data

requires careful data source curation

About

Secure, tailored access control for large language models

Unfragile Review

Knostic addresses a critical gap in LLM deployment by providing granular, role-based access control and data filtering for enterprise teams using large language models. It's a specialized security layer that lets organizations restrict what data models can access and what outputs users can see, making it invaluable for regulated industries.

Pros

+Fine-grained permission controls prevent unauthorized data exposure in multi-user LLM environments
+Seamlessly integrates with existing LLM workflows without requiring model retraining
+Built specifically for compliance-heavy sectors like healthcare and finance that can't risk LLM hallucinations accessing sensitive information

Cons

-Narrow use case means it only solves one problem—won't help teams that need general LLM optimization or cost reduction
-Requires significant setup and security architecture planning, not suitable for teams wanting plug-and-play solutions
