Software vulnerability detection and remediation
DepthFirst builds intelligence for detecting and remediating critical software vulnerabilities, carrying through to the fix rather than stopping at the alert. That second half is where most security tooling leaves off, and where the backlog accumulates. Its premise is that software now underpins most functioning infrastructure, which makes unresolved vulnerabilities a question of resilience and integrity rather than of hygiene.
