Deploy AI with Confidence.
AI Security Guardrails.
Raw AI models are unpredictable, prone to hallucinations, and vulnerable to malicious attacks. Vistaran engineers low-latency AI guardrails that act as an impenetrable firewall around your LLMs ensuring your AI stays on-topic, protects sensitive data, and adheres strictly to corporate compliance.
The Massive Liability of Unfiltered AI
Releasing a raw Large Language Model (LLM) to your customers or employees is a massive corporate liability. Without strict security layers, malicious users can exploit prompt injections to hijack your AI workflows.
Jailbreaks, system prompt leaks, and toxic advice. Raw model outputs cannot be natively governed without an active runtime filter.
We don't just prompt the AI to "be safe." We engineer a dedicated, programmable security layer that sits perfectly between the user and the LLM. Every input is scrutinized, and every output is validated before it ever reaches the screen.
Multi-Layered Protection for Generative AI
True AI security requires a defense-in-depth approach. Vistaran utilizes industry-leading frameworks like NVIDIA NeMo Guardrails, Llama Guard, and custom semantic routers to build a multi-layered shield.
Input Filtering & Prompt Injection Defense
Before a user's prompt ever reaches your core AI, our security classifiers analyze it for malicious intent. We instantly block jailbreak attempts, role-playing exploits, and malicious code injections, shutting down attacks at the perimeter.
PII / PHI Redaction & Anonymization
We build intelligent scrubbers that scan user inputs for credit card numbers, Social Security Numbers, patient names, and private addresses. Sensitive data is anonymized into secure tokens before reaching the LLM, and safely de-tokenized only upon final output.
Topical Restrictions & Semantic Routing
We define strict conversational boundaries for your AI. By using advanced semantic analysis, our guardrails detect when a conversation is drifting out of scope. If a user asks your e-commerce bot for financial advice, the guardrail instantly intercepts and gracefully redirects.
Output Validation & Anti-Hallucination
We don't trust the LLM's response blindly. Before the user sees the answer, our output guardrails cross-reference the AI's generated text against your approved corporate knowledge base. If the AI makes a claim that cannot be verified, the response is blocked or rewritten.
Shielding Your Most Critical Workflows
Vistaran's guardrails protect enterprise teams across their most vulnerable user touchpoints.
Customer-Facing AI Agents
Prevent PR disasters by ensuring your customer support AI never hallucinates a fake company policy, swears at a user, recommends competitors, or promises unauthorized refunds.
Internal HR & Copilots
Ensure that internal employee chatbots respect Role-Based Access Control (RBAC). Prevent a clever prompt injection from tricking the AI into summarizing confidential files, passwords, or payroll.
Healthcare & Fintech Assistants
Enforce rigid compliance. Ensure medical AI strictly provides informational summaries without attempting to clinically diagnose a patient, and financial AI refrains from offering unverified advice.
Maximum Security. Minimum Latency.
The biggest flaw with most AI guardrails is that they make the AI incredibly slow. Vistaran engineers for high-performance throughput, maintaining maximum speeds.
Latency-Optimized Architecture
We use highly optimized, lightweight classifier models that process guardrail checks in parallel, adding mere milliseconds to your response times.
Comprehensive Threat Dashboards
We don't just block attacks; we log them. We provide your CISO with a real-time dashboard showing prompt injections blocked and PII redacted.
Seamless Integration
Whether using OpenAI, Anthropic, or a locally hosted open-source model, our guardrails act as an API proxy. No core application rewrite needed.
Don't Let a Chatbot Mistake
Cost Your Enterprise.
Generative AI is powerful, but power without control is dangerous. Lock down your AI infrastructure today before an exploit or hallucination damages your brand reputation.
