How I Built NexTrace: An AI Security Guard That Actually Fixes Cloud Breaches Using FalkorDB

Description and use

NexTrace leverages FalkorDB to automatically detect and remediate attack paths in cloud environments, swiftly quarantining vulnerable services and proving zero remaining threats.

Problem

A hacker can exploit a small flaw in an unimportant service to jump through internal permissions and reach highly confidential data, while traditional security tools only alert without showing the attack path or fixing it.

Outcome

NexTrace reduced breach containment time from hours to seconds, automatically quarantining services and severing attack paths, and providing mathematical proof of zero remaining paths.

Workflow

• Upload cloud setup or simulate attack
• Query FalkorDB for blast radius (services reachable in 1‑4 hops)
• Use shortestPath() to map exact attack route
• Send Cypher write to quarantine the vulnerable service
• Delete CALLS/CAN_ASSUME edges to sever connections
• Re‑run path algorithm to confirm zero remaining paths

Evidence

Traditional security tools only send a boring email saying: "Hey, there is a bug on service X." They don't show you the road to your secrets, and they don't fix it.

Source

NexTrace doesn't just watch—it acts! It sends a live Cypher write command to FalkorDB: MATCH (s {name: 'PaymentService'}) SET s.status = 'QUARANTINED'

Finally, NexTrace runs FalkorDB's path algorithm one more time. It checks if any open roads still exist between the public internet and your private databases. When the answer is 0, it gives the security team mathematical proof that the breach is completely contained.
