Securing SIP Remote Worker with Assertion® Secure Voice™

In today’s remote working world, securing SIP (Session Initiation Protocol) connections is key to protecting enterprise communications across all industries. Assertion® Secure Voice™ is the solution to protect your remote worker infrastructure from cyber-attacks and keep communications flowing and secure. 

The Growing Threat 

With the rise of remote working, reliance on Session Border Controllers (SBCs) to manage and secure voice communications has grown. Unfortunately, these internet-exposed devices are also a target for attackers – hackers exploit vulnerabilities using stolen credentials or brute force to get in. Once in, they can make abusive calls, commit toll fraud, or even eavesdrop on sensitive conversations. Toll fraud costs Enterprises over $12 billion annually – it’s time to take advanced security seriously. 

Why Proactive Security 

Traditional methods of monitoring telecom bills for fraud indicators or tracking abnormal call patterns are reactive and often not quick enough. By the time a threat is detected, the damage is already done. Proactive real-time monitoring systems detect and mitigate threats before they get out of control and compromise your communications. 

Assertion® Secure Voice™ 

Assertion® Secure Voice™ protects your SIP remote worker infrastructure with: 

  • Cyber Attack Prevention: Blocks enumeration, brute force, and time travel attacks by blocking attacker IPs on the SBC or Firewall. 
  • Geo-Fencing: Restricts registrations to specific countries for added security. 
  • Comprehensive Call Screening: Provides traffic visibility and protects against scam calls, toll fraud, and TDoS attacks

By connecting to a global intelligence network Assertion® Secure Voice™ aggregates threat intelligence from multiple sources such as government-published block lists, crowd-sourced threat databases, and Assertion’s Secure Voice attack database collected by numerous installations, so it’s always up to date with the latest threats. 

Benefits 

Assertion® Secure Voice™ benefits many industries including finance, healthcare, technology, and more: 

  • Real-Time Threat Detection: AI-driven analysis of SIP registration messages detects attack patterns and blocks suspicious activity in near real-time. 
  • Increased Security Visibility: Provides visibility into active threats, unauthorized access attempts, and potential data breaches. 
  • Cost Savings: Prevents toll fraud incidents and reduces inflated telecom bills and operational costs. 

By using Assertion® Secure Voice™ organizations can harden their SBCs against multi-vector cyber-attacks and keep communications flowing and secure across all industries.
