A digital twin can be a helpful tool to help companies test and validate concepts ahead of their launch or to analyze the impact of potential changes to existing entities. These virtual models are designed to replicate wide ranging physical objects as well as entire cities or regions. Engineers and planners use digital twins to […]

Endpoint detection and response (EDR), network detection and response (NDR), and extended detection and response (XDR) are closely related categories of threat detection technology. Each of these tools can detect and respond to cyberattacks originating from a variety of sources, but they vary in their sophistication.  This guide will help you understand how these tools […]

At a high level, firewalls are positioned to create a protective barrier between external, potentially dangerous traffic sources and internal networks as well as within the enterprise perimeter, between segmented parts of a network. Firewalls should be placed throughout these segmented networks to ensure comprehensive protection across large enterprise networks.  Firewalls control traffic between: External […]

Network vulnerability scanning is the process of pinpointing weaknesses and vulnerabilities across a network, including evaluating network assets like computers and other devices — any potential target that could be exploited by threat actors should be included in these scans.  The basic steps for performing a network vulnerability scan are: Plan and define the scope of […]

A firewall audit is a multistep process that gives organizations insight into the status and effectiveness of the firewalls installed throughout their network. These audits provide visibility into potential vulnerabilities and the health of connections going to and from firewalls. They also uncover information about firewall changes since the last audit.  Firewalls are critical elements […]

Firewalls are network security devices that monitor and filter traffic as it flows to, from, and across networks based on a given enterprise’s pre-established security policies. Ideally, firewalls block dangerous traffic and allow non-threatening traffic. While virtually every networked organization should have some level of firewall control, not every network will require the most expensive, […]

Network detection and response, or NDR, is a cybersecurity tool that continuously scans traffic for potential risks by using machine learning and artificial intelligence (AI). When risks are encountered, NDR systems initiate an immediate counterattack and begin to repair any damage. Enterprise networks that rely solely on legacy network security tools like firewalls are much […]

Managed detection and response (MDR) adds an additional layer of protection and elevates the security postures of organizations relying on legacy solutions. Managed detection and response is becoming more popular as organizations look to outsource some elements of their cybersecurity approach. As bad actors become more adept at bypassing traditional network security platforms, managed services […]

Network Detection and Response (NDR) is a network security approach that identifies and stops network threats that have gone otherwise undetected by traditional network gatekeeping tools. NDR is sometimes called Network Traffic Analysis (NTA). At a high level, NDR tools examine traffic for unusual or unexpected traffic and network behaviors that could indicate an imminent […]

Internet of Things (IoT) edge computing trends reflect the recent increase in the adoption of both edge computing and IoT among enterprises and individual consumers.  Gartner predicts that 75% of enterprise-generated data will be processed outside a traditional data center or cloud by 2025, and IDC reports that more than half of new enterprise IT […]
