ActiveFence

Enterprise AI red-teaming and runtime guardrails for GenAI apps, agents, and models—from build to production.

68/100MonitorCustom pricingContact Sales

Alice is the most research-backed AI safety platform we've seen, with a proprietary data moat powering real-time adversarial detection across 120+ languages. It's the right call for large deployments needing full-lifecycle coverage—but sales-led pricing and enterprise focus exclude small teams. If you need pre-launch red-teaming and runtime guardrails at scale, Alice beats standalone tools and moderation APIs.

Skip Alice if you're a small team or startup needing a self-serve, low-cost moderation API—Alice is sales-led, enterprise-focused, and designed for large deployments with serious compliance and safety requirements.

The 30-second take
Price reality

It's the right fit for large enterprises and AI labs that need data-moat-grade safety; smaller teams should compare with simpler API-based moderation (e.g., OpenAI Moderation) which is far cheaper but lacks red-teaming depth.

In short

About ActiveFence

Contact SalesAdvancedAPI availableAPI · Web

Alice (formerly ActiveFence) is an enterprise AI governance platform that tests, protects, and monitors AI applications and agents from build to production. Purpose-built for frontier model labs, large platform companies, and regulated industries like finance, healthcare, and child safety, Alice addresses the full spectrum of GenAI risk: harmful content, prompt injection and jailbreaks, governance gaps, and reputational exposure. The WonderSuite platform includes WonderBuild for pre-launch automated red-teaming, WonderFence for dynamic runtime guardrails on live apps and agents, and WonderCheck for continuous red-teaming and drift detection in production. All are powered by Rabbit Hole, an adversarial intelligence engine with billions of toxic, manipulative, and abusive samples across 120+ languages, supporting multi-modal detection and real-time adaptation to emerging threats. Key differentiators include adaptive policy alignment that tunes coverage to regulatory needs and risk tolerance, agentic AI guardrails for autonomous systems, child safety protections for AI toys, and a Financial Benchmark that flags unauthorized financial advice. The platform reports protecting over 3 billion users and handling over 1 billion daily AI-human interactions. Integrations span major cloud and model providers: AWS, Azure, Google Cloud, OpenAI, Anthropic, Cohere, Meta, Amazon AGI, NVIDIA, and Databricks Unity AI Gateway. With a Red-Team Lab for hands-on adversarial testing and a technical docs hub, Alice recently raised $140M led by Apax Digital, bringing total funding to $280M and working with 8 of the 10 top AI labs. Compared to standalone red-teaming tools or simple content moderation APIs, Alice's unified approach and data moat make it the choice for organizations with serious compliance and safety requirements—not for teams wanting a self-serve moderation API.

Behind the Verdict

Alice (formerly ActiveFence) has carved out a distinct niche: it's not a content moderation API you can plug in over a weekend; it's a full-lifecycle AI trust, safety, and security platform for organizations where a single safety failure is existential. Strengths include the Rabbit Hole data moat—billions of toxic, manipulative, and abusive samples across 120+ languages, updated in real time—which gives its classifiers a level of adversarial understanding that generic moderation APIs can't match. The WonderSuite trio (WonderBuild, WonderFence, WonderCheck) covers pre-launch stress-testing, runtime guardrails, and ongoing drift detection, making it a one-stop shop for GenAI governance. Agentic guardrails for autonomous systems and the Financial Benchmark are ahead of many competitors. Weaknesses: pricing is sales-led only; there's no self-serve tier or free trial, so small teams can't evaluate it without a sales call. Integration effort is significant—this isn't a turnkey API. It may be overkill for simple toxicity filtering, where something like OpenAI's moderation API or Perspective API would be cheaper and easier. Where it fits: frontier model labs (works with 8 of the top 10), platform companies with millions of users, and regulated industries like finance, healthcare, and child safety. Recent $140M funding round (August 2026, led by Apax Digital) signals strong market confidence. Where it doesn't: small teams, hobby projects, or anyone needing a self-serve moderation solution under $50K/year.
