VERDICT

Should I use Home Page | CISA?

Cybersecurity and Infrastructure Security Agency: America's Cyber Defense Agency - cisa.gov

Skip. Nothing to buy: CISA is the U.S. federal cyber defense agency, not software — its free KEV catalog and advisories suit any organization's threat intel. Skip it if you're shopping for a security product with support, SLAs, and a contract.

Confidence

Medium. Based on 6 relevant public sources; most returned search results were unrelated noise, and no independent product reviews exist because CISA is not a product.

Gotchas - check before you buy

KEV is US-government prioritization; it supplements rather than replaces your vulnerability process

No pricing or procurement path: as a federal agency, there is nothing to buy
