Zero Trust

Zero Trust Network Access (ZTNA) has quickly become more than a cybersecurity buzzword. It’s the modern blueprint for secure, flexible, and scalable remote access. For organizations balancing hybrid work, multi-cloud deployments, and a growing list of connected devices, ZTNA represents a fundamental shift in how we think about trust on the network. At Portnox, that…

Zero trust network security represents a major evolution in how organizations defend their data and systems. Rather than assuming trust based on location or network boundaries, this model enforces verification at every point of access. In this article, we’ll explain what zero trust means in practice, why it’s become essential to modern cybersecurity strategies, and…

What does Zero Trust for Multi-Cloud mean?  Zero trust for multi-cloud environments means extending the core principles of zero trust security to networks that span multiple cloud providers, ensuring that no user, device, or application is inherently trusted and that access is granted based on continuous verification and least privilege, regardless of location or network.   Here’s…

As enterprises move away from VPNs and perimeter-based access models, Zero Trust Network Access (ZTNA) is quickly becoming the gold standard for secure, scalable remote access. But not all ZTNA solutions are created equal. Some require agents. Others only focus on identity without device context. Many promise “zero trust” while offering little more than access…

For decades, the Virtual Private Network (VPN) was the de facto standard for remote access. But with today’s workforce operating from everywhere—and applications no longer confined to on-prem environments—VPNs are falling short. That’s where Zero Trust Network Access (ZTNA) steps in. This guide breaks down the key differences in the ZTNA vs. VPN debate, and…

What is BYOD Onboarding?  Bring Your Own Device (BYOD) onboarding is the process of securely connecting employee-owned devices—like smartphones, laptops, and tablets—to a corporate network or system, typically for work-related tasks. It is a critical component of Bring Your Own Device (BYOD) programs, which allow employees to use personal devices for business purposes.    Why BYOD Onboarding Matters  As…

What is a non-human entity? A non-human entity (NHE) in cybersecurity and identity management refers to anything that interacts with digital systems but isn’t a person. These entities still need identities and permissions—just like users—but they operate automatically or programmatically. Why non-human entities matter in cybersecurity Just like human users, non-human entities can be exploited…

What is ZTNA Security? ZTNA Security (Zero Trust Network Access Security) is a cybersecurity framework designed to provide secure and controlled access to an organization’s applications, data, and resources. It is based on the principle of “zero trust,” meaning no user or device is trusted by default, even if they are within the network perimeter.…

What does zero trust mean in cybersecurity? Zero Trust in cybersecurity is a security framework that operates on the principle of “never trust, always verify.” It assumes that no user, device, or system—whether inside or outside the network—can be inherently trusted. Instead, it requires continuous validation of identity, access permissions, and device security posture before…

What is SIEM? SIEM (Security Information and Event Management) is a cybersecurity solution that provides organizations with the ability to monitor, detect, analyze, and respond to security incidents in real time. It combines Security Information Management (SIM) and Security Event Management (SEM) capabilities into a single platform to provide a comprehensive view of an organization’s…

What is a zero trust extended framework? A Zero Trust Extended Framework (ZTX Framework) builds upon the traditional Zero Trust model to create a more comprehensive, holistic approach to securing enterprise networks, data, and resources. It extends beyond simply verifying user identity and device health to ensure every component, including applications, data, network infrastructure, and…

What are zero trust edge solutions, and how do they enhance network security? Zero Trust Edge (ZTE) solutions are an evolution of the Zero Trust security model, integrating network security principles with cloud-based architecture. ZTE aims to secure users, devices, and resources regardless of their location, providing unified access control and threat prevention. It operates…
