garak vs NVADER

garak is a command-line scanner for probing language models and systems that use them for security weaknesses. Its checks cover issues such as hallucination, data leakage, prompt injection, misinformation, toxicity generation, and jailbreaks. Probes try to elicit failures, while detectors inspect responses for patterns such as unsafe content or a failure to refuse. A standard scan can run without supervision and produce a report, with scan settings available for customization. Integrations include OpenAI, Hugging Face, Cohere, Replicate, AWS Bedrock, LiteLLM, REST-accessible models, and custom Python integrations. Hugging Face models can run locally or be accessed through an inference API or private endpoint. Output includes screen results, a detailed report log, a hit log, and a debug log. garak assesses text output only. It is developed in Linux and OSX and can be installed with pip or from source; listed platforms include Linux, macOS, Windows, and self-hosted use. It is free, with a free plan and no free trial. Listed capabilities include custom metrics, LLM-as-a-judge, and safety evaluations.

NVADER is a cloud-based security scanner for AI apps, code, agents, integrations, MCP servers and dependencies. Its five scanners cover apps, repositories, MCP servers, skills and hallucinations, with automated attacks including prompt injection, jailbreaking, data extraction, code and agent vulnerabilities, and hallucinated dependencies. Reports rank findings by severity, highlight critical issues and provide fix guidance. Findings can be mapped to OWASP LLM Top 10, MITRE ATLAS, CWE, OWASP Top 10 and NIST AI RMF. Visitors can run a free app scan by entering a link without creating an account. The Free plan covers one app and App Scan; Starter costs $49 a month for one app and all five scan types, while Pro is $149 a month for up to five apps. Specialist reviews, assessments and managed services are also listed at separate prices. NVADER says source code is scanned in an isolated container and deleted, prompts are not retained after processing, and findings are kept for 12 months. SCAN is available now; WATCH and DEFEND are described as coming.
