Epic, Real-World

Adversarial Intelligence

Our solutions outperform industry benchmarks because they're powered by data drawn from a decade of real-world adversarial research, enabling you to act before abuse becomes news.

The Rabbit Hole

Data Moat

With billions of continually updated toxic examples, we train sharper classifiers and fuel stronger red-teaming, giving you unmatched accuracy and coverage.

Adaptive, Customizable

Policy Alignment

Keep your policies front and center, tuning coverage to your regulatory needs and risk tolerance - across every modality, so each interaction stays trusted and aligned.

The internet is a wonderful place. Mostly.

Wherever people and technology meet, powerful tools can be manipulated to do harmful things. And you’re held accountable.

Unintended GenAI Behavior

GenAI can produce harmful or misleading content at a scale traditional security and safety controls can’t reliably manage.

Application-Level Exploitation

Prompt injection, jailbreaks, and model exploits expose applications, agents, and integrations to data leakage or abuse.

Governance and Compliance Gaps

Abusive, harmful, or non-compliant interactions undermine security and safety policy enforcement and responsible AI governance.

Reputational and Trust Exposure

A single failure can trigger legal liability, regulatory scrutiny, stalled innovation momentum, and lasting damage to brand trust.

‍Rabbit Hole

Alice is powered by Rabbit Hole, built on billions of toxic, manipulative, and abusive data samples and cross-cultural expert analysis. Rabbit Hole adapts in real time, foreseeing emerging threats, surfacing unseen risks, and feeding guardrails, enabling Alice to test, harden, and protect systems of every kind: from UGC to GenAI and soon enough, humanoid robots.

It’s what enables us to protect half the world’s online users from harm, and why leading technology companies and frontier model labs rely on Alice at scale.

What’s New from Alice

Securing Agentic AI: Meeting the 2026 Federal Assurance Bar
Learn how the FY2026 NDAA and new NIST frameworks are shifting agentic AI from experimental to regulated. Master the security controls and Zero Trust principles required to win federal AI contracts this year.
Learn MoreWe Audited the OpenClaw Marketplace. We Found a Trojan.
A malicious “Skill” for the OpenClaw AI framework, titled “RememberAll”, is currently being distributed via the ClawHub marketplace. While purporting to be a personal reminder utility, the skill contains hidden instructions to download a secondary payload (secure-sync) that harvests sensitive credentials (API keys, .env files) and exfiltrates them to a public ntfy.sh dead-drop resolver.
