Applications and servers are the fundamental components that must be secured in order to protect mission-critical data and operations. However, for their functioning, they rely on network architectures and communication protocols that seamlessly enable operations in an increasingly interconnected world.

Network architectures (from the classic perimeter-based model to the modern zero trust paradigm), communication protocols (wired and wireless, used to transport data or voice) and network devices (switches, routers, firewalls, application proxies, load balancers, etc.) are constantly evolving to support business needs.

Security assessments can be conducted on all types of network architectures and communication protocols, including:

• IPv4 and IPv6
• IPsec and TLS VPNs
• Voice over IP (VoIP)
• Wi-Fi
• NFC and RFID
• Bluetooth
• LoRaWAN

By mapping the attack surface of networks, security assessments allow to identify vulnerabilities and exposures and ensure integration of best practice security controls for the protection of mission-critical communications.
