# Guardoster

*/Startups/Guardoster*

## Startup Overview

This inline filtration layer intercepts and strips adversarial prompts and hallucinations from large language model pipelines. The system processes both inbound user queries and outbound model responses, evaluating text against strict safety boundaries before it reaches the application layer.

Engineering teams deploying generative AI face constant threats from prompt injection attacks and unpredictable model fabrications. Relying on manual prompt tuning leaves production applications vulnerable to jailbreaks and structural failures. This engine removes the risk by evaluating traffic programmatically without disrupting core application logic.

Unlike alternatives such as Nvidia NeMo Guardrails or Azure Content Safety that introduce noticeable processing lag, the architecture is latency-optimized for real-time inference. It functions as a schema-aware firewall, enforcing strict output formatting rules so downstream systems receive exact data structures alongside guaranteed safety.

## Startup Offer

**Proof**:
- Targeting a less than 50ms latency overhead for real-time inference applications.
- Aiming to enforce 100% strict schema adherence before payloads reach the end user.
- Designed to intercept known jailbreaks and injection attacks before they consume downstream LLM compute.
**Tiers**:
- Name: Developer Pipeline · Price: ~$0.001–$0.003 per API evaluation · Inclusions: Standard adversarial prompt filtering, basic JSON schema validation, and up to 100k evaluations per month.
- Name: Production Guard · Price: ~$400–$800/mo + ~$0.005 per overage evaluation · Inclusions: 1 million evaluations, custom schema enforcement, hallucination checks, and priority routing for sub-50ms latency.
- Name: Enterprise Edge · Price: Custom: ~$30k–$70k/yr · Inclusions: Unlimited volume, VPC peering, zero data retention guarantee, and custom fine-tuned evaluation models.
**Guarantee**: If an adversarial prompt successfully bypasses the active filters or an output fails the enforced strict schema, we will refund your API usage fees for that billing cycle.
**Business Function**: ProvideService
**Objection Handlers**:
- Objection: Adding another API layer will introduce unacceptable latency to our chatbot. Rebuttal: Guardoster is explicitly latency-optimized, running lightweight evaluation models at the edge aimed at adding less than 50ms to the round trip.
- Objection: We already use system prompts and native JSON modes to control output. Rebuttal: Native JSON modes ensure syntax but do not prevent hallucinated values or malicious payload injections; we filter intent and strict schema parameters independently.
- Objection: We cannot send sensitive user prompts to a third-party security tool. Rebuttal: The Enterprise tier is designed for zero-retention, processing payloads entirely in memory so no proprietary text is ever logged or stored.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A 14-day shadow API deployment mirroring production chatbot traffic to validate the less than 50ms latency overhead claim under peak load.
- A 30-day staging integration running known jailbreak attack libraries against the evaluation models to prove zero bypassed adversarial prompts before full enterprise rollout.
**Target Metrics**:
- Target: less than 50ms latency overhead per API round trip during real-time inference.
- Aim: 100 percent strict schema adherence before payloads reach the end user.
- Target: 0 proprietary user payloads logged or retained in memory during Enterprise processing.
- Aim: 100 percent interception of known jailbreaks and injection attacks before downstream compute is consumed.
**Target Case Studies**:
- A mid-market fintech VP of Engineering implementing Guardoster to intercept jailbreak attempts before they consume expensive LLM compute, ensuring automated financial advisory bots output strict JSON without prompt injections.
- An enterprise healthcare CISO adopting the zero data retention tier to filter hallucinated medical data in memory, achieving strict schema compliance without logging sensitive patient data.
- A consumer AI startup Lead Developer routing high-volume chatbot traffic through the edge API, maintaining sub-50ms latency while blocking adversarial prompts at scale.
**Testimonial Targets**:
- Head of AI Development highlighting how intercepting malicious payloads at the edge significantly reduces wasted LLM token spend.
- Chief Information Security Officer praising the zero-retention memory architecture for passing rigorous internal compliance audits without friction.
- Senior Backend Engineer expressing relief that hallucinated values are caught before crashing the downstream application database.

## Startup Top Risks

**Risks**:
- Severity: existential · Description: Foundation model providers natively implement flawless schema-enforcement and prompt-injection defenses that make third-party guardrail middleware obsolete. · Mitigation Status: unmitigated
- Severity: high · Description: The added inference latency from the filtering layer exceeds strict real-time application thresholds, causing application builders to abandon the tool. · Mitigation Status: in-progress
- Severity: moderate · Description: High false-positive filtering rates block valid user inputs and harmless LLM responses, degrading the end-user experience and causing customer churn. · Mitigation Status: in-progress
- Severity: low · Description: Security-conscious enterprise customers demand isolated on-premise deployments, fracturing the engineering codebase and slowing down core product iteration. · Mitigation Status: mitigated
