What is EDR (Endpoint Detection and Response)
What EDR actually detects, how it differs from antivirus, XDR, and MDR, and why supply chain attacks like XZ Utils and 3CX slip past it entirely.
What is SIEM
SIEM explained: how it works, what data feeds it, how it differs from SOAR/XDR, and where reachability-based supply chain security fills its blind spots.
FAQ: How Much Does Supply Chain Security Cost?
Real numbers for supply chain security in 2026 — tool spend, headcount, hidden costs, SMB vs enterprise ranges, and where teams over- and under-invest.
What is SOAR
SOAR explained: what Security Orchestration, Automation, and Response actually does, how it differs from SIEM, and where it fits in supply chain security.
Board-Level Supply Chain Security Reporting
A practical template for reporting software supply chain risk to the board, including the three slides that work, the language that does not, and common traps.
What is an Intrusion Detection System (IDS)
An IDS detects malicious network or host activity after it happens. Learn what an IDS is, how it differs from an IPS, and why supply chain attacks need more.
What is an Intrusion Prevention System (IPS)
An IPS blocks malicious traffic inline in real time, but it can't stop supply chain attacks hidden inside trusted code and dependencies.
What is Network Segmentation
Network segmentation limits breach blast radius by isolating systems into enforced zones. Learn the types, common mistakes, and how to implement it in hybrid clouds.
What is Multi-Factor Authentication (MFA)
MFA blocks over 99% of credential-based attacks, but Uber, Cisco, and Twilio breaches show how push-bombing and AiTM phishing still get around it.
What is Single Sign-On (SSO)
SSO lets users log in once to access many apps — but it also concentrates identity into one high-value target. Here's how it works and its real risks.
What is a Security Operations Center (SOC)
A clear breakdown of what a Security Operations Center (SOC) is, how it's staffed, the tools it runs, and how it differs from a NOC or CSIRT.
What is Incident Response
What incident response actually means, its four NIST phases, and why supply chain attacks like Log4Shell and SolarWinds break traditional response assumptions.
