What is the main difference between NeuralTrust and AI Security Gateway?

NeuralTrust is an enterprise AI security platform with red teaming, MCP Gateway, agent inventory, and multiple enforcement surfaces — built for companies with dedicated security teams. AI Security Gateway is a developer-first, fully open-source (Apache 2.0) AI governance gateway with two-line integration, transparent pricing, cost routing, and budget enforcement — built for dev teams and startups that need governance today.

Is AI Security Gateway open source?

Yes. AI Security Gateway is fully open source under the Apache 2.0 license. You can read every line of code, self-host it anywhere, contribute to it, or fork it. NeuralTrust's core products are not open source in the same way.

How does AI Security Gateway pricing compare to NeuralTrust?

AI Security Gateway publishes transparent pricing: a free tier with 1M credits, Starter at $9/month, and Pro at $29/month with zero-markup BYOK. NeuralTrust requires contacting their sales team for pricing, which is typical for enterprise security platforms but less accessible for startups and small teams.

Does AI Security Gateway have red teaming or MCP Gateway like NeuralTrust?

No. Red teaming, MCP Gateway, and agent inventory are NeuralTrust strengths that AI Security Gateway does not currently offer. If automated adversarial testing or agent-to-tool security are requirements, NeuralTrust is the stronger choice. AI Security Gateway focuses on PII redaction, prompt injection blocking, cost routing, and budget enforcement with the simplest possible integration.

Can I try AI Security Gateway without a sales call or enterprise contract?

Yes. Sign up, get an API key, and change two lines in your OpenAI SDK (baseURL and apiKey). PII redaction, prompt injection blocking, budget enforcement, and cost routing are active from the first request. The free tier includes 1M credits. No sales call, no POC, no enterprise contract required. You can also self-host the open-source code from GitHub.

NeuralTrust Alternative — Open Source, Transparent Pricing & Cost Routing

Comparison based on publicly available documentation as of May 2026. Features may have changed — check each provider's current docs for the latest.

NeuralTrust is a well-funded AI security company with offices across Europe and the United States. Their product suite — TrustGate (AI Gateway), TrustLens (Agent-SPM), AI Threat Detection, MCP Gateway, and MCP Scanner — is purpose-built for enterprises with dedicated security teams, procurement processes, and compliance mandates like the EU AI Act.

NeuralTrust's strength is breadth and depth of enterprise security: traffic monitoring, threat detection, policy enforcement, red teaming, agent inventory, and multiple enforcement surfaces. If you have a CISO, a security team, and an enterprise procurement process, NeuralTrust is a serious contender.

AI Security Gateway takes a different approach: fully open source (Apache 2.0), two-line integration, transparent pricing, cost routing, and budget enforcement built in. It's designed for dev teams and startups that need AI governance today — without an enterprise sales cycle, without opaque pricing, and with full access to the source code.

Why This Matters

The difference between an “enterprise security platform” and a “developer-first governance tool” is the difference between a product you evaluate for months and one you ship with today.

Enterprise Platform

Schedule a demo. Get a quote. Run a POC with your security team. Negotiate contracts. Deploy across Gateway, Browser, API, and Endpoint surfaces. Integrate TrustLens for observability. Plan for EU AI Act audits. Timeline: weeks to months.

Developer-First Tool

Change two lines in your OpenAI SDK. PII redaction, prompt injection blocking, budget enforcement, and cost routing are active from the first call. Read the source code on GitHub. Pay $0 to start. Timeline: minutes.

What NeuralTrust Does Well

NeuralTrust is a comprehensive AI security platform with capabilities that go well beyond a typical gateway. Credit where it's due:

Red teaming and adversarial testing

A full automated red teaming suite that probes your AI systems for vulnerabilities — prompt injection, jailbreaks, data extraction, and more. This is a dedicated product, not an afterthought. If your compliance framework requires adversarial testing, NeuralTrust delivers it natively.

MCP Gateway and MCP Scanner

NeuralTrust has a dedicated MCP Gateway for securing agent-to-tool communication, plus an MCP Scanner that audits MCP servers for security risks. As agent architectures grow more complex, this is a genuinely differentiated capability.

Observability and agent inventory (TrustLens)

TrustLens provides full tracing, agent discovery, and lifecycle management. If you need to know what agents are running, what tools they're calling, and how they're behaving — TrustLens is purpose-built for that.

Multiple enforcement surfaces

NeuralTrust enforces policies across Gateway, Browser, API, and Endpoint — covering more touchpoints than most competitors. This matters for enterprises with diverse deployment topologies.

EU AI Act compliance positioning

NeuralTrust is explicitly positioned for EU AI Act compliance, with European offices and regulatory expertise. For companies navigating EU regulatory requirements, this is a meaningful advantage.

Where the Approaches Differ

NeuralTrust and AI Security Gateway solve overlapping problems for different buyers. These aren't gaps — they're trade-offs that reflect different design philosophies:

critical

Open source vs proprietary

AI Security Gateway is fully open source under Apache 2.0. You can read every line, self-host anywhere, and fork if needed. NeuralTrust's core products are not open source in the same way — you're trusting a vendor with your security layer. For teams that require source code access for audits, compliance, or vendor risk, this is a fundamental difference.

critical

Transparent pricing vs enterprise-gated

AI Security Gateway publishes pricing on the website: free tier with 1M credits, Starter at $9/month, Pro at $29/month. NeuralTrust requires contacting sales for pricing. If you're a startup or small team, you shouldn't need a sales call to know what something costs.

high

Cost routing and budget enforcement

AI Security Gateway includes real-time cost routing (auto-selects cheapest provider per request) and pre-flight budget enforcement (per-project spend caps with hard 402 rejection). NeuralTrust focuses on security enforcement, not cost governance — you'll need separate tooling for billing control.

high

Two-line integration vs SDK configuration

AI Security Gateway works by changing baseURL and apiKey in your existing OpenAI SDK — two lines, no new SDKs, no configuration files. NeuralTrust's TrustGate requires its own integration setup and policy configuration. Both approaches work; one is faster to start with.

medium

Managed wallet credits

AI Security Gateway offers a managed wallet mode where teams without provider accounts can start immediately — 1M free credits included. The Smart Router handles provider selection and billing. NeuralTrust is geared toward teams that already have enterprise provider relationships.

medium

Free public leak checker

AI Security Gateway provides a free, zero-signup PII leak scanner at aisecuritygateway.ai/ai-leak-checker — useful for quick checks before any commitment. NeuralTrust's security tools require an account and evaluation process.

The AI Security Gateway Approach: Governance in Two Lines

AI Security Gateway is built as a developer-first governance gateway. Security, cost control, and compliance ship as defaults — not as features you configure after procurement:

Request→PII Scan (28 types)→Injection Block→Budget Check→Cost Route→Provider

Fully Open Source (Apache 2.0)

Every line of code is on GitHub. Audit it, self-host it, fork it. No vendor lock-in, no trust-us-it's-secure — verify it yourself. Contributions welcome.

Smart Cost Routing

Real-time price indexing across providers. The Smart Router auto-selects the cheapest available model for each request — savings vary by model and provider mix.

Billing & routing docs →

Pre-flight Budget Enforcement

Per-project spend caps with hard enforcement. Every request is cost-estimated before forwarding — if the wallet is insufficient, a 402 is returned. No surprise bills, no overruns.

Budget enforcement deep dive →

Two-Line Integration

Change baseURL and apiKey in your existing OpenAI SDK. That's the entire integration. PII redaction, injection blocking, budget enforcement, and cost routing are active from the first call.

Enterprise Platform vs Developer-First Tool

The fundamental architectural difference: who is the primary buyer?

Enterprise platform(NeuralTrust)

1. Schedule a demo with the sales team

2. Get a custom quote based on your volume

3. Run a POC with your security team

4. Deploy TrustGate + configure policies

5. Integrate TrustLens for observability

6. Set up red teaming schedules

7. Configure MCP Gateway for agent security

Setup time: weeks to months. Full security suite included.

Developer-first tool(AI Security Gateway)

1. Sign up (or self-host from GitHub)

2. Get your API key

3. Set baseURL + apiKey in your SDK

4. Send your first request

PII redaction, injection blocking, budget enforcement — all active immediately.

Try AI Security Gateway

If you're evaluating NeuralTrust and want to see what a developer-first approach looks like, here's the entire integration. Your existing OpenAI SDK code works as-is — just change two lines:

Before — direct OpenAI SDK

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-xxxxx",
});

After — through AISG (PII + injection blocking + budget + cost routing)

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "os_hub_your_key_here",
  baseURL: "https://api.aisecuritygateway.ai/v1",
});

// That's it. No SDK to install, no policies to configure.
// PII redaction, prompt injection blocking, budget enforcement,
// and cost routing are active from this first call.

No enterprise contract. No sales call. No new SDK. Your existing code, models, and response handling stay exactly the same — with governance added at the proxy layer.

When to Use Each

NeuralTrust

Best for enterprises with security teams and compliance mandates:

•You have a CISO and a dedicated AI security team
•Red teaming and adversarial testing are compliance requirements
•You need MCP Gateway for agent-to-tool security
•Agent inventory and lifecycle management (TrustLens) is a priority
•EU AI Act compliance is a hard requirement and you need a vendor with European regulatory expertise
•You need enforcement across Browser, Endpoint, and API surfaces (not just API gateway)

AI Security Gateway

Built for dev teams that need governance today, not next quarter:

•You want to read and audit the source code (Apache 2.0)
•You need governance in production this week, not after a POC
•Cost control matters — you want cost routing and budget enforcement built in
•You don't want opaque enterprise pricing — you want $0 to start, $29/mo Pro
•Startups without provider accounts (use Managed Credits + Smart Router)
•You need BYOK at 0% markup with no enterprise contract
•Privacy-first: prompts are never stored (stateless architecture)
