Protect your IT infrastructure
Network security broadly encompasses the various methods and technologies used to protect network infrastructure and the data that flows through it from unauthorized access, misuse and theft.
Spanning the entire connected infrastructure, from core applications and systems to the very edge of the IT perimeter, network security is essential for any organization that relies on its network for operations, services or communication. It involves using software, hardware, policies and processes to protect against external cyber attacks, and ensuring authorized users have secure access to work effectively.
With decades of experience in network infrastructure and design, WWT has deep insight into how to defend against threats both known and unknown.

Network segmentation
Network segmentation is the practice of dividing a large network into smaller sub-networks, each with specific security protocols and rules. Controlling access to network segments helps improve network performance, limit cyber attack damage, protect vulnerable devices and reduce the scope of compliance.
- Macro-segmentation divides the network into broader segments or zones, significantly enhancing the overall security posture by compartmentalizing the network infrastructure.
- Micro-segmentation offers a more refined level of control, allowing for the regulation of traffic down to the workload or process level within each segment.
- Network access control (NAC) forms the cornerstone of monitoring and managing access to the network, offering critical insights into network-connected devices and user activities.

Network observability
Network observability involves gaining deep visibility into network activities to enable proactive management, swift anomaly detection and efficient troubleshooting. In the process of designing, configuring, monitoring and maintaining network devices and services, communication and data should be exchanged in a secure environment. This ensures the availability, performance, security and scalability of the network infrastructure, which supports the critical functions and operations of an organization. It also helps prevent adversaries from exploiting vulnerable network services and access points, while reducing the impact of incidents in case of a compromise.
- Network detection and response (NDR) uses artificial intelligence, machine learning and behavioral analytics to better identify anomalies and suspicious patterns that indicate known or unknown attacks.

OT and IoT security
Digital innovations in IoT-based asset management, analytics, supply chain optimization, demand-driven offerings and intelligent forecasting drive transformation in OT security. Relying on network isolation alone cannot guarantee secure operations. As business demands enhanced operational efficiency and maximized profitability, organizations must also rigorously manage risks across IT and OT security networks to avoid costly outages, catastrophic failures and theft of trade secrets.

Application and API security
Applications (both web and mobile), by design, increase your attack surface in today's digital-first economy. It's increasingly important to secure these business-critical applications and the application programming interfaces (APIs) that support them. Every code commit introduces risk, such as a new or changed endpoint (API), the exposure of sensitive data (PII, PCI, PHI), new open-source dependencies, new technologies (DB, authentication framework), business logic, data flows, and more. These applications and APIs require high availability and performance yet demand the highest level of security and observability.
