Splunk

Cisco · United States

Splunk's query language and app ecosystem run so deep in security operations that ripping them out feels like replacing the nervous system. The lock-in has a price: ingest licensing commonly lists at 100 to 180 dollars per gigabyte per day. Since March 2024 the company is owned by Cisco, which paid 28 billion dollars to fold it into its US portfolio.

Jurisdiction: United States
GDPR by default: Requires DPA + TIA
US CLOUD Act exposure: Yes

Why choose Filigran over Splunk?

The decisive argument is data jurisdiction. Splunk is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

Filigran removes that overhead. As a France-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
