Throughput. Latency.Cost. The Three-Way Tug of War Every AI Team Faces
NEYSA AEGIS LLM SHIELD
Enforce Security Policy at Every LLM Endpoint
Aegis LLM Shield sits between your users and your AI models. It blocks prompt injection, jailbreaks, redacts PII, and enforces your security policies on every request — without changes to your application code.
THE CHALLENGE
Unguarded LLM Endpoints are a Compliance
and Security Problem
Prompt Injection Is the #1 LLM Risk
One crafted prompt can override your model’s instructions, extract data, or hijack its behavior entirely. It is the #1 threat to LLM applications according to OWASP.
Data Leakage Kills Trust
Sensitive information disclosure moved up to #2 on the OWASP LLM Top 10 for 2025. LLMs with access to PII, financial data, or IP can inadvertently expose it in responses.
Compliance Can’t Wait
~60% of enterprise AI initiatives stall before production due to data privacy and governance concerns. Regulatory frameworks (GDPR, HIPAA, DPDP) now demand enforceable AI safeguards.
Scattered Guardrails Don’t Scale
Hard-coding safety checks into every app creates fragile, inconsistent protection. Security teams have no central visibility or control over what flows through LLM endpoints.
INTRODUCING NEYSA AEGIS LLM SHIELD
A Single Pane of Glass to Control What Your LLMs Can See and Say
Aegis LLM Shield gives security teams a single place to define, enforce, and monitor LLM policies. Input filtering, output controls, PII redaction, topic restrictions – all configurable without touching application code.
Aegis LLM Shield is integrated directly into the Velocis Developer Hub – the same console where teams provision GPUs, deploy models, and manage inference endpoints.
Available as an add-on to your Velocis plan
HOW IT WORKS
From Endpoint to Shielded Endpoint in Minutes
Step 1 : Pick your LLM endpoint and workspace
In the Velocis Developer Hub, select any inference endpoint and attach an Aegis Shield configuration. Aegis picks up the endpoint’s model, environment, and workspace automatically.
Step 2 : Set the rules for every incoming prompt
Set the policies that apply to every prompt before it reaches the model.
Prompt injection detection & blocking - PII/sensitive data filtering (redact or block)
- Topic restrictions and content moderation
- Custom keyword and regex filters
- Rate limiting per usergroup, app, or endpoint
Step 3 : Configure output guardrails
Set the policies that apply to every model response before it reaches the user:
- Toxic/harmful content filtering on responses
- PII redaction in model outputs
- System prompt and instruction leakage protection
- Configurable guardrail refusal responses
- Non-sensical output and noise suppression
Step 4 : Enable & monitor
Activate Shield on the endpoint. From that point, every request is inspected in real time. Review violations, see which rule fired and why, refine policies, and iterate.
CAPABILITIES
Built to Defend the Runtime Risk
of OWASP LLM Top 10
PLATFORM-NATIVE
Native Integration with the Neysa Velocis Platform
Standalone LLM firewalls sit outside your infrastructure. They add a proxy hop, require their own access control, and have no context about your workspace structure or team roles. Aegis LLM Shield is built into the Velocis Developer Hub, the same console where your teams provision compute, deploy models, and manage inference endpoints.
What that means in practice:
Up and running in minutes
Enabling or disabling Shield on any endpoint is a single toggle. No DNS changes, no proxy config, no SDK updates required.
Workspace-aware policies
Inherit project and workspace for contextual governance.
Security and endpoint health, together
Shield status, policy config, and violation logs are visible directly in your endpoint view, alongside endpoint health and deployment info.
Uses the RBAC you already have
Shield follows your existing RBAC model. No separate access control system to set up or maintain.
No separate invoice
LLM Shield usage is billed through your existing Velocis statement. No separate vendor invoice.

Secure your LLM app with a simple API call. Get instant security verdicts for prompts and responses across any environment in just few lines of code.
ENTERPRISE-READY
Security and Compliance, End to End
Security and compliance are embedded into every layer of Neysa’s platform — both at the cloud infrastructure and model level.
- OWASP LLM Top 10 Security — Aegis is purpose-built to secure all inference-time risks in production, defending against LLM01, LLM02, LLM07, LLM10, with additional LLM06 safeguards.
- GDPR / PCI-DSS / HIPAA / DPDP / PCI-DSS alignment — PII detection and redaction configurable per regulation
- Full audit trail — every blocked prompt, modified response, and policy violation is logged and exportable
- Zero-trust by default — inherits Velocis infrastructure-first security (encryption at rest and in transit, RBAC, SSO integration)
