October is Cybersecurity Awareness Month, and we’re launching an educational one-pager series spotlighting the policies and frameworks that shape our collective defense. The first edition, CISA 2015: What It Is and Why It Matters, unpacks the now-expired Cybersecurity Information Sharing Act of 2015 (CISA 2015), a landmark law that made it safer for public and private organizations to share threat intelligence. Its expiration raises pressing questions about the future of cyber defense. Check out our one-pager to understand why renewing CISA 2015 isn’t just procedural — it’s critical to maintaining the resilience of our national cybersecurity ecosystem.
