CISA (Cybersecurity & Infrastructure Security Agency)

Overview

CISA is the operational lead for federal cybersecurity. Think of them as the “Cyber FBI” strictly focused on defense and resilience. They issue official alerts regarding massive national vulnerabilities (like critical infrastructure hacks) and provide free, high-quality guidelines for organizations.

Why It Matters

For small business owners and IT professionals, CISA’s “Known Exploited Vulnerabilities Catalog” is the ultimate source of truth. If CISA tells you to patch a server, you drop everything and patch it immediately.
