Convert risk to resilience with Cribl Guard

Does sensitive data flowing through your network feel like a ticking time bomb? Well, it just might be. Legal mandates, security frameworks, and customer expectations have made the stakes higher than ever. One leaked spreadsheet of personally identifiable information (PII) can wipe out years of customer trust, rack up regulatory fines, and invite ransomware actors to your doorstep. And PII is just the tip of the iceberg — internal system configs, application secrets, and other business-critical data are all sensitive and must also stay hidden from the wrong eyes.

Meet Cribl Guard: real-time protection that moves as fast as your data

Cribl Guard sits directly inside Cribl Stream (our telemetry pipeline), scanning every event in real time. Advanced AI features can flag Social Security numbers, credit-card details, passport data, and other sensitive patterns the moment they appear. Cribl’s built-in “human-in-the-loop” checkpoint lets operators maintain control with the final say to approve, override, or even tweak each decision on the fly — then mask, block, or route the data before it exits the pipeline. The result is fewer leaks, reduced false positives, faster response, and airtight compliance without mountains of manual work.

Never have to ask, “Do we know what we have?”

Most teams suspect sensitive data lurks in their logs but can’t pinpoint where or how much. Cribl Guard changes that. It gives you instant visibility, automatic remediation, and an auditable trail for regulators — all while reinforcing customer trust and smoother data-governance practices.

Real-world control in just three steps

  • Out-of-the-box protection — Identify, mask, encrypt, or delete sensitive data before downstream tools ever see it.

  • Smart routing — When an event does contain sensitive data, modify it, forward it to a secure quarantine or to authorized analysis destinations. 

  • Continuous assurance — Monitor live dataflows so you know, in real time, that nothing sensitive is slipping through the cracks.

Five features that make it happen for you

  1. Real-time detection and action — Scan live streams of data and act instantly on customizable rules.

  2. Flexible rulesets — Choose from rich out-of-the-box patterns or roll your own with regex and context tags. 

  3. Seamless pipeline integration — Drop Guard into any Cribl Stream pipeline; target only the fields you care about.

  4. Comprehensive monitoring — Track events, bytes scanned, and detections to fine-tune your policy and prove compliance.

  5. AI-driven insights — Let machine learning adapt to data drift, recommend new rules, and trim false positives.

The bottom line

Manual hunts for sensitive data are slow, error-prone, and expensive. Cribl Guard combines advanced AI with a human-in-the-loop control point to spot sensitive data, such as credit card, passport, and Social Security numbers, as it flows through Cribl Stream. It surfaces the important stuff for human decision-making. Compliance gets simpler, storage costs drop, and your security posture tightens as Cribl Guard helps detect sensitive data contextually (not just regex), reducing false positives and supporting GDPR, CCPA, HIPAA, PCI, and audit requirements. Whether you’re fully cloud or hybrid, Cribl Guard puts you firmly in control of every piece of sensitive information that crosses your pipes.
