The US Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) has assembled an online list of free and open source security tools and services — including its own — in an effort to help organizations improve their security posture.
CISA calls the list a "living repository" of free tools and services provided by private- and public-sector organizations that will updated as needed with new resources. The freebie list maps to four goals from the agency's "CISA Insights: Implement Cybersecurity Measures Now to Protect Against Critical Threats" recommendations:
- Reducing the likelihood of a damaging cyber incident
- Detecting malicious activity quickly
- Responding effectively to confirmed incidents
- Maximizing resilience
Among the types of free tools in the list compiled by CISA: CISA's vulnerability scanning and incident response services, Microsoft's Defender Application Guard, Microsoft Defender Antivirus, Google Safe Browsing, Cloudflare Zero Trust Services, and Mandiant Attack Surface Management.
