LevelBlue Security Colony: A Practical Cybersecurity Resource Hub for CISOs

Few cybersecurity knowledge repositories are as broad, deep, or widely respected as LevelBlue Security Colony.

Detect human names in logs with ML in Sensitive Data Scanner

Modern applications generate a constant stream of logs, some of which carry more information than they should. For too many organizations, logs include personally identifiable information (PII) such as customer names that were never meant to leave production systems. Teams try to limit this data exposure by using regular expressions to detect and obfuscate matches, only to discover that names like John O’Connor, Mary-Jane, Jane van der Meer, and A. García slip through.

Staying PCI DSS Compliant: The Annual Checklist

Payment Card Industry Data Security Standard (PCI DSS) compliance isn’t a once-a-year exercise; it’s a year-round effort that requires regular validation to protect cardholder data, manage risk, and maintain audit readiness throughout the year. Compliance failures are rarely caused by a single missing control.

Entity Detection Plus Protection: Nightfall's New Approach to Comprehensive DLP

For years, data loss prevention has meant one thing: finding sensitive entities. Social Security numbers, credit card numbers, API keys—if you could pattern-match it, you could protect it. But this approach has always had fundamental limits. What happens when you need to protect customer IDs unique to your business? What about proprietary source code that doesn't contain any traditional PII?

The CISA ChatGPT Incident Makes the Case for AI-Native DLP

The acting director of America's Cybersecurity and Infrastructure Security Agency—the person tasked with defending federal networks against nation-state adversaries—triggered multiple automated security warnings by uploading sensitive government documents to ChatGPT. If this happened at CISA, it can happen at your organization too.

What does a virtual CISO (vCISO) actually do?

A virtual CISO is your on-demand cybersecurity resource. We provide the same strategic leadership as an in-house CISO, without the full-time commitment. vCISOs are used by organisations that need experienced security leadership to meet their compliance requirements, manage cyber risk, and guide security decisions, but don’t yet have a permanent CISO, or may have an interim requirement for a vCISO.

Manic Monday: A Day in the Life of Threat Hunting

John, a Cyber Threat Intelligence (CTI) analyst, turns to look at his CISO. He seems a bit rattled. John responds, “Yeah. Huge story.” “Massive. The board is worried and wants to know if this puts us at risk. We’re secure, right?” John hesitates.“Let me get back to you on that.” The CISO walks away. John races to his desk.

How to Compare Cloud Security Tools: The Evaluation Framework

You’re not struggling to find cloud security tools. You’re struggling to compare them meaningfully. Every vendor claims “comprehensive coverage” and “real-time detection.” Their feature matrices look identical. Their demos all show impressive dashboards catching simulated attacks.
