In their own words
Giskard
Giskard provides tools for assessing AI agents before production, with coverage for prompt injection, data disclosure, inappropriate content, hallucinations, contradictions, and omissions. Its Hub performs black-box testing of conversational text-to-text agents available through an API endpoint. An assessment produces a structured report with a deploy-or-fix verdict, ranked vulnerabilities, and functional scenarios; passing agents receive a Giskard Label. Giskard describes a remediation process in which its team qualifies findings, discusses severity, prioritizes issues, opens workflow tickets, and reruns tests to check fixes. Enterprise evaluation options include adversarial probes, domain-specific datasets, RAG quality metrics, customizable metrics, and human review interfaces. Deployment choices include on-premise, private cloud, and SaaS. Giskard lists EU or US data residency, access controls, audit trails, identity-provider integration, encryption, and a zero-training policy, alongside GDPR, SOC 2 Type II, and HIPAA compliance. The free plan includes a local open-source library, basic vulnerability scanning and RAG evaluation, community support, and best-effort maintenance.
NVADER
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.
