AI content filtering
The prompt firewall protects inputs. Content filtering protects outputs. Together, they provide bidirectional security for every AI interaction.
Why outputs need filtering
AI models can generate harmful, biased, or policy-violating content even from benign prompts. Jailbroken models may produce inappropriate responses. RAG-augmented responses may contain PII from retrieved documents. Malicious injection attacks may manipulate model output for social engineering.
Filtering categories
- Toxicity — Detect and block hate speech, threats, harassment, and abusive language
- PII in responses — Catch sensitive data generated or echoed by the model
- Factual safety — Flag demonstrably false claims in critical domains (medical, legal, financial)
- Policy compliance — Ensure responses align with organizational use policies and brand guidelines
- Code safety — Detect insecure code patterns, hardcoded credentials, and vulnerable dependencies in AI-generated code
Bidirectional protection
Complete AI security requires both input and output inspection. PromptWall provides the prompt firewall for input protection and content filtering for output protection — governed by the same policy engine with consistent enforcement across all surfaces.
Deploy content filtering
Protect users from harmful AI responses with real-time output filtering.
Frequently asked questions
What is the difference between content filtering and content moderation?+
Content filtering is proactive — it blocks harmful content before it reaches the user. Content moderation is reactive — it reviews content after delivery. PromptWall provides real-time filtering that prevents harmful AI outputs from ever being displayed.
Can I customize content filtering rules?+
Yes. Tenant administrators configure filtering rules based on content categories (toxicity, violence, sexual content, PII), severity thresholds, and enforcement actions. Different departments can have different filtering profiles.
Does content filtering apply to both input and output?+
PromptWall provides full bidirectional protection: the prompt firewall inspects inputs (PII masking, injection detection), and content filtering inspects outputs (toxicity, policy violations, harmful content). Both directions use the same policy engine.
