What AI Security Gateway does
AI Security Gateway (AISG) is a Naperville, USA-based software company founded in 2025 that operates an OpenAI-compatible governance proxy for LLM traffic. The platform scans every inbound prompt for 30+ PII entity types (SSNs, credit cards, emails, API keys, addresses, and others) using Microsoft Presidio as a base NLP engine extended with 15+ proprietary detection signatures, then redacts or blocks sensitive data before requests reach any underlying model provider. Additional core capabilities include heuristic prompt-injection blocking, hard budget enforcement (HTTP 402 on cap breach), fingerprint-based recursive agent-loop protection, semantic prompt caching, smart cost routing across 600+ models on 8 providers, and tamper-evident hash-chained audit logs aligned with EU AI Act Article 12 (effective August 2026). The product supports text, image (via direct base64 OCR), code, and multimodal requests, and is offered as managed cloud, on-prem Hybrid VPC deployment, or fully self-hosted Apache 2.0 open source.
The company monetizes through a four-tier model: a free managed-credits tier (1,000,000 free credits, no credit card), a $9/month Starter BYOK plan capped at three projects, a $29/month Pro BYOK plan with unlimited projects at 0% markup, and a custom-priced Enterprise tier bundling Hybrid VPC, SAML SSO, RBAC, and SIEM connectors. Go-to-market is product-led, targeting developers through self-serve onboarding, free tooling, GitHub distribution, and explicit comparison pages against Cloudflare AI Gateway, Portkey, Helicone, LiteLLM, OpenRouter, and Vercel AI Gateway. Enterprise sales motion addresses regulated industries — healthcare (HIPAA), financial services (PCI-DSS), and EU deployments (GDPR, EU AI Act) — that require data sovereignty, compliance audit trails, and integration with Splunk, Datadog, Microsoft Sentinel, Okta, Azure AD, and Google Workspace.

AI Security Gateway product offering
Product offeringCore offering
AI Security Gateway provides an OpenAI-compatible governance proxy that sits between applications and any LLM provider, scanning every prompt and image for PII, blocking prompt injections, enforcing hard per-key spend caps with HTTP 402, smart-routing to the cheapest of 600+ models across 8 providers, and emitting tamper-evident audit logs for EU AI Act Article 12 compliance. The platform is sold as a managed cloud, an on-prem Hybrid VPC (compiled Go proxy inside the customer's network), or an Apache 2.0 self-hosted open-source build, and is complemented by a free AI Leak Checker web tool.
Product overview
AI Security Gateway is a single unified governance platform for LLM infrastructure, combining an OpenAI-compatible proxy with DLP firewall, SSO, SIEM connectors, and Hybrid VPC deployment. The core product (AI Security Gateway) is complemented by the free AI Leak Checker tool, a native Python SDK (pip install aisg), and EU AI Act compliance logging. The platform offers four pricing tiers: Free Managed Credits (1M credits), Starter BYOK ($9/mo for 3 projects), Pro BYOK ($29/mo for unlimited projects), and Enterprise (custom with Hybrid VPC, SAML SSO, and SIEM connectors). Smart cost routing routes requests across 600+ models from 8 providers, while the AI Firewall provides 30-entity PII redaction, vision OCR scanning, prompt injection blocking, and per-project versioned DLP policies. The entire stack is available as managed cloud, hybrid VPC, or fully self-hosted (Apache 2.0 open source).

AI Security Gateway competitors and assessment
Company assessmentBroad incumbents
- Microsoft Azure AI Content Safety: Native Azure service providing content filtering, PII detection, and groundedness detection for Azure OpenAI deployments. Represents provider-side risk where native PII controls could commoditize proxy-layer DLP like AISG's.
- Portkey: AI gateway focused on LLM routing, failover, and observability, acquired by Palo Alto Networks in May 2026. Named competitor; AISG positions against it by emphasizing native DLP, SSO, SIEM, and on-prem deployment that Portkey lacks.
- Vercel AI Gateway: AI gateway integrated into the Vercel platform providing caching, routing, and observability for deployed AI applications. Named competitor; benefits from Vercel's frontend deployment ecosystem rather than security/governance focus.
- Cloudflare AI Gateway: Cloudflare's LLM proxy offering caching, routing, and observability. Directly named by AISG as a peer; broader platform with no native DLP, SSO, or Hybrid VPC — represents the incumbent AISG competes against in routing/caching.
Emerging players
- WhyLabs: AI observability and guardrails platform for LLM applications with monitoring, policy enforcement, and security features. Adjacent to AISG with more emphasis on observability and policy authoring rather than inline PII redaction.
Direct peers
- Helicone: Open-source LLM observability platform with prompt logging, caching, and analytics. Named competitor; focuses on passive observability rather than AISG's active DLP/intervention model.
- OpenRouter: Multi-model LLM routing service aggregating models from many providers behind a single API. Named competitor on AISG comparison pages; competes on routing breadth rather than governance/security.
- Protecto: AI data privacy and PII redaction platform that masks sensitive data before it reaches LLMs. Directly comparable core capability to AISG's AI Firewall; competes in the same enterprise PII-redaction-for-AI segment.
- Lakera Guard: AI security platform specializing in prompt injection defense, PII detection, and content moderation for LLM applications. Closely comparable to AISG's AI Firewall feature set, with deeper specialization on adversarial prompt defense.
- LiteLLM: Open-source LLM proxy/gateway providing unified API across 100+ models with routing and load balancing. Named competitor on AISG's comparison pages; overlapping routing functionality but lighter native security feature set.
