Prompt Security & Threat Prevention
Attackers and careless users craft inputs that override system instructions or embed hidden characters. Spro detects and neutralizes prompt injections, jailbreaks, and zero-width attacks before they reach models.
The Spro Advantage
Normalize and strip invisible/zero-width characters
Static and dynamic prompt analysis for injection patterns
Behavioral filters to block instruction-override attempts
ML + heuristic scanning pre-run with logging and neutralization
Key Benefits
- Dramatic reduction in jailbreak and exfiltration incidents
- Preserves integrity of system prompts and model instructions
- Actionable signals for security teams
- Fewer high-risk outputs reaching users or systems
Success Scenario
"Input containing `\u200b` attempts to retrieve system prompts — Spro detects and rejects it."
"Hidden-instruction injection is neutralized and logged for triage."
"Heuristic scan flags suspicious sequence and rewrites to a safe prompt."
