Security Intelligence

💡 Credential Stuffing at Scale

Credential stuffing uses stolen username-password pairs from data breaches to attempt logins across many websites. Since users frequently reuse passwords, these automated attacks achieve success rates of 0.1-2%, which translates to thousands of compromised accounts from millions of attempts.

💡 Satellite Internet Security

Satellite internet introduces unique security challenges including high latency that affects real-time threat detection, shared bandwidth that enables traffic sniffing, and coverage areas that cross multiple jurisdictions complicating legal response.
