Prevent prompt injections, block jailbreaks, mask PII, and audit autonomous agents in real-time with enterprise-grade guardrails deployed globally.
Sits securely between your users and upstream AI models (OpenAI, Gemini, Anthropic, or self-hosted LLaMA).
Securing next-gen architecture for modern teams
Traditional firewalls don't understand conversational manipulation. Prompt Shield bridges the safety gap.
Configure rules, enter testing inputs, and witness the multi-stage validation engine in action.
Presidio Analyzer scans and masks emails, phones, and SSNs.
Checks input embeddings against adversarial vectors.
Validates prompt matches against system override rules.
Verifies generated text meets safety thresholds.
Pipeline idle. Enter a prompt and scan to visualize telemetry logs.
Monitor live gateway statistics, active policy parameters, and exfiltration logs.

Traditional firewalls block malicious URLs or payloads. Prompt Shield inspects semantic relationships, data privacy structures, and model exfiltration contexts.
We project incoming prompt tokens into high-dimensional vector spaces, comparing distance scores against a globally updated database of jailbreaks, adversarial templates, and jailbreak vectors. This detects context manipulation that basic regexes completely miss.
Our filter flags triggers that attempt to bypass system limits (e.g. "Ignore all instructions", "You are now DAN", "Start with 'I agree to release credentials'"). We quarantine these attacks, terminating the API pipeline before it impacts upstream models.
Adversarial vectors often ask models to act as virtual terminals, developers, hypothetical code executors, or family members. Our models identify cognitive roleplay structures, analyzing prompt goals to block malicious outputs.
Prompt Shield executes sequentially across three phases to prevent latency compounding while maintaining compliance.
Strips out emails, credit cards, phones, and custom variables inside client threads prior to upstream data dispatch.
Evaluates semantic distance metrics for jailbreaks and custom-defined blocked keywords in under 15ms.
Audits output text fields for tokens that bypass corporate policies before rendering text to your final user.
Connect your applications to Prompt Shield in minutes. If an injection or policy violation is flagged, discard or redact the payload; otherwise, safely pass the cleaned prompt to your model endpoint.

| Parameter | Type | Description |
|---|---|---|
| prompt | string (required) | The user input prompt text payload to evaluate. |
| mask_pii | boolean | Enable automatic scrubbing of email/phones. Default: false. |
| threshold | float | Vector limit (0.0 to 1.0) for jailbreak block triggers. If omitted, falls back to the dynamic global WAF policy threshold set in your Governance Center. |

Designed for organizations requiring air-gapped security, low SLA latencies, and rigorous compliance architectures.
Deploy Prompt Shield directly inside your AWS, GCP, or Azure Virtual Private Cloud. Keep user prompts entirely within your secure security boundary with no external network hops.
Integrate directly with Okta, Active Directory, or Google Workspace via SAML/OIDC. Enforce roles, control who can update policies, and audit admin activities.
Our contracts include dedicated support channels, customized SLAs for edge GPU clusters, and prompt responses from security engineers.
Prompt Shield is architected to satisfy stringent compliance guidelines. We help security audits verify that data passed to Large Language Models is masked and monitored for risks.
Scale your AI shield with transparent monthly volumes. Custom VPC deployments available for enterprise.
For testing, hobbyists, and early-stage prototypes.
For production applications, scaling agents, and startups.
For corporate architectures requiring VPC deployments and compliance.
We do not automatically shut down your API keys. We apply a soft grace limit and email your team to upgrade to a higher tier with no service interruptions.
Yes. Standard plans (Developer and Growth Pro) are billed month-to-month and can be canceled at any time from your account settings.
Absolutely. Contact our sales department to custom outline a pricing structure aligned with high-volume agents or high-volume user apps.
Generative AI represents a paradigm shift in software development. However, letting external text control model output exposes corporate pipelines to severe security vulnerabilities.
We founded AI Prompt Shield to solve this exact problem. By inspecting prompt interactions semantically in under 50ms, our edge nodes protect backend systems from injections, data exfiltration, and privacy compliance violations without bottlenecking development.
We build with transparency and high-performance engineering to provide safety infrastructure for the next generation of autonomous web systems.
We are always looking for passionate engineers, safety researchers, and customer champions.
