New capability detects PII, identifies prompt injection attempts, and flags toxic content so you can block risky AI outputs before they reach downstream systems

Zapier, the leading AI orchestration platform, today announced “AI Guardrails by Zapier”, a set of builder-added safety checks that run directly inside automated workflows. AI Guardrails lets teams detect personally identifiable information (PII), identify prompt injection attempts, and flag toxic or harmful content before AI outputs ever touch a CRM, database, or customer inbox.

As companies push AI deeper into daily operations, the gap between "we use AI" and "we trust our AI outputs" keeps getting wider. Most organizations have AI policies on paper. What they don't have is a way to enforce those policies right where the work happens. AI Guardrails closes that gap by embedding real-time safety checks directly into Zaps, Agents, and MCP-connected tools.

"Every company using AI in production has the same question: how do we know the outputs are clean before they hit our systems?" said Brandon Sammut, Chief People & AI Transformation Officer. "AI Guardrails gives teams an actual enforcement layer, not a policy document sitting in a shared drive somewhere. It runs inline, in production, on every single workflow that needs it."

How AI Guardrails Works

AI Guardrails allows you to add a safety step directly into any workflow. After an AI model generates output, the guardrail checks it against the selected detection type and returns structured results. From there, teams can use paths and filters to route, block, or escalate, all without writing code. Current capabilities include:

• PII Detection: Scans AI-generated text for more than 30 types of personally identifiable information, including Social Security numbers, credit card numbers, bank details, email addresses, and physical addresses. Detected PII can be automatically blocked or redacted before it moves downstream.
• Prompt Injection Blocking: Reviews user or external input before it reaches an AI model, catching attempts to manipulate the model's behavior.
• Jailbreak Detection: Flags attempts to bypass an AI model's built-in safety controls.
• Toxicity Detection: Screens content for hate speech, threats, insults, and other harmful language before it gets published, forwarded, or stored.
• Sentiment Analysis: Gauges the tone of AI-generated or user-submitted content with confidence scores, so teams can route negative or mixed-sentiment outputs for human review.

AI Guardrails works across Zapier's platform. In Zaps, teams add a guardrail step after any AI action. In Agents, it functions as a tool the Agent is instructed to use before acting on AI output. And through MCP, AI clients like Cursor and Claude can call guardrail actions directly.

Closing the Trust Gap in AI Automation

AI Guardrails represents a unique capability in the automation space. While other platforms rely on documentation and manual review processes to manage AI safety, Zapier offers inline, automated safety checks that run as part of the workflow itself. Every check returns structured output, making it straightforward to build conditional logic around safety results without any custom code.

"The conversation around AI safety usually stops at 'we wrote a policy,'" said Sammut. "What teams actually need is something that runs in the background and catches problems before they become incidents. That's what this does."
