## Our take

What our shortlists say about the one we picked.

### [Securonix Unified Defense SIEM](https://cybersectools.com/tools/securonix-unified-defense-siem)

Best for: One cloud platform for SIEM, UEBA, SOAR and threat intel

It makes the list because SIEM, UEBA, SOAR and threat intel come as one cloud platform, so a large SOC can drop several separate products. 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.
