That suits firms that ship software to others or must answer for the licenses in their code. Plan setup time and skilled people for the first rollout, because event-based scans across many repositories need care to set up.

That fits mid-market and enterprise teams with heavy event volumes. Vista Equity Partners has owned Securonix since 2022, so ask how the ThreatQuotient platform will merge into the main product.
