Today’s episode digs into the scariest cybersecurity threat in NG911…
the one sitting INSIDE your network.
Session Border Controllers and Firewalls keep your ESInet safe — until they don’t. And too often, the biggest disruptions to 9-1-1 call delivery come not from nation-state attackers or ransomware groups, but from misconfigured security rules designed with the best intentions.
In this episode, Fletch explores:
- How SIP SBCs can block legitimate 9-1-1 calls
- Why silent drops are so dangerous
- The hidden impact of rate-limiting and DPI engines
- The difference between generic VoIP rules and NG911-aware rules
- How firmware updates break PSAP call flow
- Real examples from the field (no naming names!)
- What every ECC should audit quarterly
- Why NG911 security must be both strict and aware of public safety protocols
If you’ve ever wondered how a single unchecked firewall or SBC rule can disrupt emergency services for an entire county, this episode is going to open your eyes.
