Kayvrn

Kayvrn is an outside-in security-monitoring platform for businesses that need to understand what an attacker can see from the internet. Enter a domain and Kayvrn runs 57 automated external checks across email security, websites, DNS, cloud services, exposed APIs and related attack-surface signals. No agent, internal credentials or network disruption is required. Results are organised into a plain-English, prioritised report—Fix Now, Fix Soon and Observation—so a business can act without first translating a conventional vulnerability dump. Paid plans add weekly monitoring, scan-over-scan comparison, subdomain discovery, staff-email breach monitoring, CVE and known-exploited-vulnerability alerts, PDF reporting and API access. Initial results are designed to arrive in under 30 minutes.
