Geolocation Intelligence

Problem

Security and statistics pipelines needed geographic context for traffic (country/continent) so policies and DLP/threat systems could act on where flows originate or terminate — not just IP addresses.

How it works

• IP addresses from live flows are looked up against a MaxMind GeoIP database loaded into memory.
• Lookups return structured location metadata such as country and continent codes (and optionally richer city/subdivision data when enabled).
• Matching is direction-aware: policies can evaluate source-side or destination-side geography independently for ingress vs egress traffic.
• Matched geo attributes enrich network statistics and security logs, and feed geo-filtering rules used by threat detection and data-loss protection.

What I built / owned

• Implemented direction-aware geolocation enrichment for egress/ingress traffic flows.
• Integrated MaxMind-backed geo lookup into the policy/asset matching path so rules can filter by country or continent.
• Enabled geo metadata on statistics and security logs for better operational visibility and incident analysis.

Impact

Operators can apply geo-based controls and investigate incidents with clear geographic context on both sides of a flow, improving threat detection and DLP effectiveness.
