Why on-premise for phone CDRs

Phone CDRs are sensitive: they contain extension numbers, calling parties, durations, and destinations. Sending them outside your network is rarely a choice, often a constraint.

Your CDRs stay inside your networkWhiteboard illustration: Alcatel PBX, Natalia appliance and your teams stay inside your premises; the public cloud is blocked at the perimeter.Your premises Alcatel PBX Natalia appliance Your teams RGPD ✓  NIS 2 ✓DPA art.28: noneCISO ✓ sovereignNetwork boundaryPublic cloudblocked at perimeter

Natalia On-Premise vs the market

Most legacy on-premise phone analytics tools predate GDPR. They do not articulate a Strict / Connected modes choice, and they rarely expose an immutable audit log out of the box.
