How this list was built
A company is on this list if LeadWave tags it as cybersecurity, or its description or website presents a security product. A SOC 2 badge alone doesn't count.
The data comes from LeadWave's database of SaaS and AI companies, last updated in October 2026. Companies that share a website are counted once. Headcount, funding and CEO come from public sources, so some fields are blank for smaller companies.
