Network security
Secured connectivity for the AI supercycle
The AI supercycle depends on trusted, secure connectivity across optical, IP, fixed, mobile, core and data center systems. However, new threats are emerging, including AI-enabled and quantum-computer-initiated attacks. Telecommunication providers must secure networks against these dangers to protect services, revenue and customer trust while improving resilience. Secured connectivity enables faster threat detection and response, ensuring continuity, compliance with evolving regulations, and the confidence to advance connectivity and monetize AI-driven opportunities.
Cut SOC noise and speed response
Add visibility and automation to your network to reduce alert fatigue, prioritize incidents, and accelerate investigation and remediation.
Detect and stop DDoS in seconds
Use real-time analytics and automated mitigation to detect DDoS rapidly and sustain service availability, even as attacks grow more complex.
Go quantum-safe and stay compliant
Adopt crypto-agile, standards-aligned security to protect data in flight, manage keys and certificates, and meet evolving regulations.
Enabling trusted connection for AI

Frequently asked questions
Secured connectivity ensures that every layer of the network, across optical, IP, fixed, mobile, core and data center domains, is protected against evolving threats. This includes faster threat detection and response, stronger resilience against disruptions such as DDoS attacks, and the ability to maintain service continuity. It also enables compliance with evolving regulations and standards, helping organizations protect revenue, customer trust and critical infrastructure while supporting AI-driven services at scale.
Preparing for future quantum-computer-initiated attacks requires a shift toward crypto-agile and quantum-safe security. Operators need to adopt a defense-in-depth approach that protects data in flight today while enabling a smooth transition to post-quantum cryptography (PQC). This includes implementing strong encryption, centralized key management and scalable security architectures that can evolve as standards change. By starting early, organizations can reduce long-term risk, maintain compliance and ensure their networks remain secure as quantum computing capabilities emerge.
