automated llm vulnerability scanning with multi-detector pattern
Giskard implements a modular detector architecture that automatically scans LLM outputs against 10+ vulnerability classes (hallucination, prompt injection, harmful content, sycophancy, information disclosure, stereotypes, faithfulness violations, implausible outputs, character injection, output formatting). Each detector inherits from a base scanner class and uses LLM-as-judge evaluation to identify issues without manual test case creation. The framework orchestrates detectors through a ScanReport that aggregates findings and generates remediation test suites.
Unique: Uses a pluggable detector architecture where each vulnerability class (hallucination, injection, bias, etc.) is a separate detector inheriting from a base scanner, enabling independent scaling and customization. The ScanReport abstraction automatically converts scan findings into executable GiskardTest suites, closing the gap between vulnerability discovery and test automation.
vs alternatives: More comprehensive than point-solution tools like Promptfoo (which focus on output comparison) because it detects structural vulnerabilities like hallucination and prompt injection through LLM-as-judge evaluation rather than regex or keyword matching.
rag system component-level evaluation with automated test generation
The RAG Evaluation Toolkit (RAGET) provides end-to-end evaluation of retrieval-augmented generation systems by decomposing them into evaluable components (Generator, Retriever, Rewriter, Router). It automatically generates diverse question types from a knowledge base (factual, multi-hop, reasoning-based) and measures component performance using metrics like correctness, faithfulness, relevancy, and context precision. The framework uses LLM-as-judge to score outputs against reference answers and generates comprehensive evaluation reports with component-level breakdowns.
Unique: Decomposes RAG systems into independently evaluable components (Retriever, Generator, Rewriter, Router) rather than treating them as black boxes, enabling root-cause analysis of performance degradation. Automatically generates diverse question types from knowledge bases using LLM-based generation rather than requiring manual test curation.
vs alternatives: More granular than generic LLM evaluation frameworks like LangSmith because it provides component-level metrics and automatic test generation specific to RAG architectures, rather than generic output comparison.
stochasticity and calibration analysis for model reliability assessment
Giskard detects stochasticity (inconsistent outputs for identical inputs) and calibration issues (overconfidence or underconfidence in predictions) by running models multiple times and analyzing output variance and confidence distributions. The framework identifies models that produce different outputs for the same input (indicating non-deterministic behavior) and detects overconfident models (high confidence on incorrect predictions) or underconfident models (low confidence on correct predictions). Results are reported with statistical measures of inconsistency.
Unique: Detects both stochasticity (output inconsistency) and calibration issues (confidence miscalibration) through repeated model runs and statistical analysis, enabling reliability assessment beyond single-run evaluation. The framework provides per-sample inconsistency detection rather than aggregate statistics.
vs alternatives: More comprehensive than single-run evaluation because it detects non-deterministic behavior and calibration issues that only appear across multiple runs, rather than assuming deterministic behavior from a single evaluation.
data leakage detection with feature correlation and information disclosure analysis
Giskard detects data leakage by analyzing feature correlations (identifying spurious correlations between features and targets that indicate data leakage) and information disclosure vulnerabilities (detecting when models reveal sensitive training data or unintended information). The framework uses statistical analysis to identify suspicious correlations and LLM-as-judge to detect information disclosure in model outputs. Results identify potentially leaked features and suggest remediation.
Unique: Combines statistical correlation analysis (detecting spurious correlations indicating leakage) with semantic analysis (LLM-as-judge detection of information disclosure), enabling detection of both statistical and semantic data leakage. The framework provides per-feature leakage risk assessment.
vs alternatives: More comprehensive than statistical-only leakage detection because it combines correlation analysis with semantic information disclosure detection, enabling detection of leakage that manifests as both statistical anomalies and semantic information revelation.
harmful content and toxicity detection with semantic classification
Giskard detects harmful content (hate speech, violence, illegal activity, sexual content) and toxicity in model outputs using LLM-as-judge evaluation with configurable harm categories. The framework classifies detected harmful content by type and severity, enabling risk-based filtering. Detection results identify problematic outputs and can trigger automated remediation (output filtering, model retraining).
Unique: Uses LLM-as-judge evaluation with configurable harm categories to detect harmful content semantically rather than relying on keyword matching or regex patterns. The framework provides per-category harm classification and severity scoring.
vs alternatives: More flexible than keyword-based content filters because it uses semantic analysis to detect harmful content that evades keyword matching, and more comprehensive than single-category detectors because it classifies multiple harm types (hate speech, violence, sexual, illegal).
stereotype and bias detection in llm outputs
Giskard's stereotype detector identifies when LLM outputs contain stereotypical or biased representations of groups (demographic, occupational, etc.). The detector uses LLM-as-judge evaluation with bias-specific prompts to assess whether outputs reinforce stereotypes or exhibit discriminatory language. This enables detection of subtle biases that are difficult to capture with keyword matching.
Unique: Implements stereotype detection using LLM-as-judge with bias-specific evaluation prompts, enabling semantic understanding of stereotyping beyond keyword matching. Supports evaluation across multiple demographic dimensions through configurable judge prompts.
vs alternatives: More nuanced than keyword-based bias detection because it understands context and intent; more comprehensive than single-dimension bias detection because it evaluates multiple demographic groups; more integrated than standalone bias detection tools because detection is part of the unified testing framework.
information disclosure and privacy leak detection
Giskard's information disclosure detector identifies when LLM outputs inadvertently reveal sensitive information (personal data, credentials, proprietary information). The detector uses LLM-as-judge evaluation to assess whether outputs contain information that should not be disclosed, enabling detection of privacy leaks that are difficult to capture with pattern matching. This is critical for applications handling sensitive data.
Unique: Implements information disclosure detection using LLM-as-judge with privacy-specific evaluation prompts, enabling semantic understanding of sensitive information beyond pattern matching. Supports domain-specific sensitive information definitions through configurable judge prompts.
vs alternatives: More semantic than regex-based PII detection because judge understands context and intent; more flexible than fixed PII patterns because sensitive information definitions can be customized; more integrated than standalone privacy tools because detection is part of the unified testing framework.
output format validation and parsing
Giskard's output formatting detector validates that LLM outputs conform to expected formats (JSON, XML, structured text, etc.). The detector uses LLM-as-judge or parsing-based validation to assess whether outputs are parseable and match specified schemas. This is critical for applications that depend on structured outputs for downstream processing.
Unique: Implements output format validation through both parsing-based checks (for performance) and LLM-as-judge evaluation (for flexibility). Supports multiple format types (JSON, XML, CSV, etc.) through pluggable validators.
vs alternatives: More flexible than hardcoded format checks because validators are pluggable; more practical than manual format validation because validation runs automatically; more integrated than standalone format validation libraries because validation is part of the unified testing framework.
