NVADER vs RedFang

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.

RedFang is a cloud AI red-team scanner aimed at indie builders. It scans AI agents, GitHub repositories and application URLs, including listed customer-service chatbot targets. Before scanning, it requires a TXT-record or file-upload challenge to verify target ownership. RedFang says scans take five minutes and return grades from A+ to F. Seven v1 categories cover direct prompt injection, tool misuse, sensitive data leakage, output-as-attack-vector, agent overreach, denial-of-wallet and system-prompt extraction. Repository scans look for exposed keys, broken authentication and AI-introduced bugs. The stated methodology follows the OWASP LLM Top 10 threat model and tests 12 known direct prompt-injection patterns per scan. Reports can include plain-language findings, the successful prompt, a curl reproduction command, fix code and a retest. PDF and HTML exports are listed. Free preview costs nothing; Full report costs $19 a month. A shareable badge shows the latest grade, with weekly, daily or continuous scan cadence by tier.
