SanShield
Runtime AI Firewall · Independent by design

Put a firewall between your AI and everything trying to break it.

SanShield red-teams your AI to find how it breaks, then turns every finding into a runtime firewall that blocks, redacts, or escalates threats before they reach your users or core systems. RL/ML loops keep folding in new attacks, so the protection keeps re-verifying itself.

The threat

Your existing security stack can't read what your AI is saying.

Network firewalls, cloud gateways, and code scanners inspect packets and source. None of them interpret natural language. So the moment an LLM starts taking instructions, retrieving documents, and calling tools, your whole stack goes blind to the attack.

What legacy tools inspect
  • Malicious code signatures
  • Network traffic and ports
  • Known CVE patterns
  • Source-level vulnerabilities
What they never see
  • Prompts that rewrite the system prompt
  • Instructions hidden in retrieved content
  • An agent talked into a destructive action
  • Secrets escaping in a model response
Direct & indirect

Prompt injection

Users and poisoned content rewrite your system prompt to exfiltrate data or trigger actions you never authorized.

Retrieved content

RAG & context poisoning

A ticket, a web page, or a document carries hidden instructions that your model treats as trusted context.

Agent actions

Tool & tool-chain abuse

An agent chains tools into a destructive query, a payment, or a config change no human ever approved.

Model output

Secret & PII leakage

Credentials, API keys, PHI, and other users' data slip into a response and out to whoever is on the other end.

And the exploits are already in the wild

2025 – 2026
EchoLeak
CVE-2025-32711 · CVSS 9.3

Zero-click indirect injection exfiltrated SharePoint and Teams data from a single incoming email.

ForcedLeak
Agentforce · CVSS 9.4

Indirect injection drained Salesforce CRM data through an expired $5 whitelisted domain.

GeminiJack
Vertex RAG · Dec 2025

RAG context poisoning leaked corporate Gmail and Calendar contents with no user click.

GTG-1002
AI espionage · Nov 2025

Threat actors jailbroke a coding agent to run 80-90% of an intrusion campaign autonomously.

How it works

Two products. One closed loop.

Discovery that never becomes enforcement is just a report. Enforcement that never sees new attacks goes stale. SanShield ties them together: an adversarial arena and RL/ML loops surface the attacks, the firewall enforces against them, and every change gets re-verified.

Signals in

Breakroom red-teaming

Scanners and human red-teamers hammer a sandboxed copy of your AI across 18 languages and 84+ techniques.

Runtime telemetry

Live verdicts stream back from all five surfaces of your real GenAI traffic.

Threat research

Fresh attack families and in-the-wild CVEs get folded in as they surface.

SanShield Engine
RL / ML detection core
Protection out

Runtime firewall

Six inline decisions across five surfaces, with fast-path checks in about 32 ms.

Auto-tuned policies

Confirmed attack paths become live, framework-mapped policy.

Retest Delta

Every change is replayed against your own systems before it ships.

RL/ML loops fold every confirmed attack back in, so each round sharpens the next

REST APISDKMCP Guard
1

Integrate

Add a REST call, the SDK, or an MCP Guard hook at the surfaces you want to protect. A few steps, no model swap, live the same day.

2

Configure policy

Start from a security profile mapped to your framework, then dial it stricter or more permissive and simulate it against historical traffic before it goes live.

3

Observe, then enforce

Watch in observe mode, review recommended verdicts, then flip to enforce surface by surface. No surprise blocks in production.

See it intercept a live prompt-injection attempt against your own setup.

The firewall in action

One inline check. Six ways to respond.

Pick an attack and watch where SanShield catches it and what it does next. The right move is rarely just block. It can be allow, block, redact, transform, quarantine, or route to a human, chosen per surface.

Incomingsurface: input

A user tries to override the system prompt to pull an internal runbook.

The platform

Enforcement across every surface your AI exposes.

Most guardrails watch the prompt and call it a day. SanShield sits on all five runtime boundaries and returns a real decision on each one, with the evidence to back it.

Where it fits

Built for teams where one bad output is a real event.

The attack surface shifts with what your AI is allowed to do. Find the situation that looks like yours.

Healthcare & medical platforms

PHI exposure and unsafe clinical-sounding advice.

Block RAG leaks over patient records, redact PHI before it renders, and stop the model from improvising medical guidance.

Neobanks & fintech

Fraud, social engineering, and money-moving agents.

Gate payment-class tool calls behind human review, hold financial-advice overclaim, and stop transaction data from surfacing in a response.

Customer-facing support agents

Invented policies, prompt manipulation, off-brand output.

Stop users from rewriting the system prompt, and catch refunds or commitments your bot was never authorized to make.

Internal AI agents & knowledge bases

Cross-department leaks and insider misuse.

Enforce who an internal copilot can answer for, and prevent IP from one team surfacing in another team's results.

Proof, not promises

Evidence your security and compliance teams can hand an auditor.

Anyone can claim a detection rate. We would rather show you one: the same attacks replayed against your own system before and after, with decision logs your auditors can verify.

Signature asset

The Retest Delta

We run the same attacks against your system before and after deployment. The delta is the proof: exploits that landed, retested and stopped, with legitimate traffic preserved.

Before
attempts land
After
same attempts, retested

Illustrative. Your delta is measured on your own traffic, not a vendor benchmark.

Audit-ready evidence

  • Every decision is recorded in a tamper-evident hash chain.
  • Reports map to OWASP LLM Top 10, NIST AI RMF, MITRE ATLAS, and more.
  • Evidence supports your own conformity assessment, with no certification theater.

Mapped to the standards in your RFP

conformity-assessment support
OWASP LLM Top 10MITRE ATLASNIST AI RMFEU AI ActISO 42001SOC 2 readiness

SanShield supplies evidence for your governance and conformity assessments. It does not issue certifications or guarantee legal compliance, and we will never claim a detection rate we can't show you.

Why SanShield

The only validator that answers to your roadmap.

AI security is consolidating fast, and the tools you'd evaluate keep getting absorbed by the platforms they were supposed to check. A validator owned by a vendor you also buy from has a conflict baked in. SanShield stays structurally independent, so the firewall guarding your AI isn't reporting to someone else's priorities.

  • Independent ownership, no acquirer's agenda
  • Model-agnostic, works across every model you run
  • We answer to your security needs, not a parent company

Why now

The cheapest time to harden your AI is before the deadline, not after the incident.

Three forces are converging at once, and each one turns runtime AI controls from a nice-to-have into a line item with a date attached.

EU AI Act

Regulation is arriving on a clock

EU AI Act Article 5 bans are already in force. The Annex III high-risk deadline is now set to apply from December 2, 2027, which makes now the cheapest moment to harden and document, not the moment to wait.

Cyber insurance

Insurers are carving out AI losses

Carriers are adding Gen-AI exclusions and sub-limits. One example caps a $5M cyber policy at $250k for LLM-related losses, and underwriters now ask for evidence of runtime controls.

RFP & procurement

Procurement now demands evidence

Enterprise buyers screen AI vendors with ISO 42001 and CSA AI control matrices. Under Article 25, you have to hand your deployers documented testing and controls.

The mini security review

The questions your reviewers ask first.

Answered the way a security or compliance team actually asks them, so you can clear most of your checklist before the call.
