NVADER vs PromptRedTeam

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.

PromptRedTeam is an open-source tool that scans user input before it reaches a large language model. It detects direct injection, role manipulation, zero-width injection, delimiter injection, and encoded payloads. Direct-injection checks examine override keywords, conflicting instructions, and prompt structure. Role checks cover known jailbreak patterns, role-play scenarios, and bypass attempts. The tool detects hidden zero-width characters, normalizes Unicode, analyzes Base64 and other encodings, and can decode suspicious text before scanning again. Delimiter checks look for context-breaking markers, Markdown abuse, and structural manipulation. Applications can call the hosted API with a POST request to https://api.promptredteam.com/test, or run PromptRedTeam through self-hosted deployment. The live tester accepts up to 1,000 characters and allows 10 requests per minute; self-hosting provides unlimited usage. Python, JavaScript, and cURL examples are provided. The suggested workflow is to scan incoming text, then block detected threats or log them for review. PromptRedTeam is available through web, API, and self-hosted platforms, with automated detection and hybrid deployment. It is released under the MIT License.
