AI Security

Articles on AI agent security, adversarial testing, posture management, and enterprise AI risk.

Humanbound cover for "One Link Away: What 1,350 Runs Taught Us About Prompt Guardrails," a controlled study of 9 models. A terminal window for a pricing agent on SKU-4471 shows three tool calls: a clean competitor listing, a fetch of "this week's offer," and a final fetch that leaks the £118.40 unit cost disguised as 1x1x8.4.

One Link Away: What 1,350 Runs Taught Us About Prompt Guardrails

We gave nine models a pricing agent's job and a competitor page one link away from a trap. Four leaked a confidential unit cost on every run. Here is what 1,350 runs say about how much a system-prompt guardrail actually buys you.

Beyond AI Security: The Rise of AI SecOps: Splunk + Humanbound

Splunk is where most SOCs already live. Here's how Humanbound streams AI agent security findings into Splunk as structured, HMAC-signed webhooks, so agent security gets the same real-time alerting and incident response as everything else the SOC already handles.

Beyond AI Security: The Rise of AI SecOps: Microsoft PyRIT + Humanbound

PyRIT is Microsoft's open-source, research-grade red teaming framework. Here's how a point-in-time PyRIT engagement and Humanbound's continuous, compliance-mapped monitoring plug into each other, including how PyRIT's findings can train the Humanbound Firewall directly.

Beyond Moderation: Why LLM Systems Need a Policy Layer

Moderation APIs catch harm and injection attempts but fail to enforce domain-specific policy. A cross-domain evaluation shows why production LLM systems need both moderation and policy reasoning layers.

You're Still Alt-Tabbing to a Security Tool

AI agent security won't be adopted through better dashboards. It'll be adopted when it disappears into existing workflows. Embed adversarial testing into your terminal via MCP - security becomes a conversation, not a context switch.

Claude Code Security Found the Bugs. The Agents Are Next.

Claude Code Security didn’t kill security tooling—but it did signal that frontier AI labs are now security providers, and that our current models don’t cover the behavioral, contextual, and systemic risks of autonomous agents. This is where security needs to go next.

Shadow AI: The Gap Your CISO Dashboard Doesn’t Show

Your CISO dashboard tracks vulnerabilities across infrastructure, apps, and cloud—but may miss the fastest-growing risk surface: Shadow AI. See how it shows up, why legacy tools miss it, and how Humanbound reveals AI use in a governed, continuously monitored registry.
