Alternatives to PromptGuard

{"intro": "PromptGuard places a security layer between an application and its LLM provider, checking requests before they reach the model. It describes 15 detectors across six layers for threats including prompt injection, jailbreaks, PII, data exfiltration, toxicity, fraud, secrets, malware, and tool injection. It detects and redacts 43 PII types with reversible tokenization, supports managed cloud, hybrid self-hosting, and air-gapped deployment, and can instrument supported calls without changing provider code. Integrations span hosted and local providers, while zero-retention mode avoids storing prompt and response content.\n\nReaders may prefer another product when they need model assessment, adversarial testing, benchmark workflows, or regression reports instead of runtime request inspection. PromptGuard's free tier allows 20,000 scans monthly; Team costs $19 a month, and higher plans have different limits and retention periods. It also says five OWASP LLM Top 10 risks are only partially covered, including provenance verification and vector-store isolation, and its hosted service has no EU region. Compare whether you need live protection or testing, which targets and attack methods matter, reporting and customization needs, deployment choices, and how each option handles scan volume, storage, and support.", "rows": [{"ref": "sw:f5-big-ip-apm", "name": "F5 BIG-IP APM", "best_for": "Hybrid access control with device and network policies", "pricing": "Pricing on request", "key_difference": "F5 BIG-IP APM provides SSO, SCIM, device posture, and site-to-site networking rather than PromptGuard's LLM threat scanning.", "choose_when": "Choose it when controlling user and device access across hybrid networks matters more than inspecting model requests."}, {"ref": "sw:opensecureai-scanner", "name": "OpenSecureAI Scanner", "best_for": "Developer-focused prompt injection scanning", "pricing": "Free plan; paid from $49/mo", "key_difference": "OpenSecureAI Scanner returns scored findings through packages, CLI, GitHub Action, and APIs, while PromptGuard adds runtime controls and PII redaction.", "choose_when": "Choose it when you want developer-integrated scans with risk scores and private hosted detections."}, {"ref": "sw:project-moonshot", "name": "Project Moonshot", "best_for": "Open-source benchmarks and red-team reports", "pricing": "Free plan", "key_difference": "Project Moonshot emphasizes benchmark datasets, adversarial prompt generation, custom metrics, and downloadable reports instead of live request protection.", "choose_when": "Choose it when repeatable model or application assessments and custom benchmark tests are your priority."}, {"ref": "sw:airta-red-team", "name": "AIRTA Red Team", "best_for": "Authorized end-to-end attack assessments", "pricing": "Free plan", "key_difference": "AIRTA Red Team runs playbook-driven attacks through browsers or HTTP, captures evidence, and exports severity reports rather than filtering live traffic.", "choose_when": "Choose it when you need authorized black-box assessments covering agents, uploads, tool calls, and custom playbooks."}, {"ref": "sw:promptfoo", "name": "Promptfoo", "best_for": "Cross-model evaluation and CI red teaming", "pricing": "Free plan", "key_difference": "Promptfoo compares outputs across 60+ providers and integrates with CI and security tools, while PromptGuard focuses on request-path detection.", "choose_when": "Choose it when multi-model evaluations, pipeline integrations, and red-team regression checks outweigh runtime redaction."}, {"ref": "sw:pyrit-ai-security-testing-tool", "name": "PyRIT", "best_for": "Custom automated and human-led red teaming", "pricing": "Free plan", "key_difference": "PyRIT offers modular attacks, converters, scorers, datasets, and conversation memory, unlike PromptGuard's deployed security layer.", "choose_when": "Choose it when you need extensive prompt transformations, custom scoring, and repeatable multi-turn attack scenarios."}, {"ref": "sw:augustus", "name": "Augustus", "best_for": "Large vulnerability probe libraries for security teams", "pricing": "Free plan", "key_difference": "Augustus scans 210+ probes across 47 categories with 90+ detectors and multiple report formats, rather than protecting application traffic.", "choose_when": "Choose it when broad adversarial coverage, provider variety, and table, JSON, or HTML vulnerability reports are more useful."}]}
