NetGuard Network Security

Secure your radio and core network domains

Nokia NetGuard Network Security lets you use access policies and proven practices to protect your network assets and operations from a wide range of threats. 

Our solution helps you monitor network elements and prevent unauthorized access, misuse, and modification of data. It also helps you guard against distributed denial-of-service (DDoS) attacks.

With NetGuard Network Security, you can build a comprehensive security solution that combines the capabilities of three products:

  • Certificate Manager: Ensure that only authorized base stations can access the network
  • Core Network Security: Protect against attacks through the internet (Gi interface) and roaming access (Gp interface)
  • Signaling Security: Identify and mitigate threats created by exploiting known SS7 vulnerabilities

Threat Scenario: Video call interception

Certificate Manager

  • Address 3GPP security requirements with an automated, scalable, and cost-effective solution
  • Ensure that your 3GPP standardized LTE network provides the same level of security as your 3G network
  • Unify security across access technologies (macro and small cells)

Core Network Security

  • Prevent unauthorized access to core network elements
  • Prevent eavesdropping and theft of subscriber data
  • Protect your business and brand image by preventing security breaches and theft of user data

Signaling Security

  • Prevent churn by shielding customers from hackers that seek to use SS7 vulnerabilities to disrupt their service or commit fraud
  • Improve subscriber privacy with SS7 protection that keeps hackers from tracking customers’ activities or intercepting their calls
  • Protect against service disruption with a signaling firewall that blocks suspicious SS7 requests
