What is Zero Trust?

Zero trust is a cybersecurity strategy wherein security policy is applied based on context established through least-privileged access controls and strict user authentication, so each user is granted just enough access to complete their tasks. A well-tuned zero trust architecture leads to simpler network infrastructure, a better user experience, and improved cyberthreat defense.


Zero Trust Security, based on John Kindervag's principle of "never trust, always verify," grants users only the necessary access to complete their tasks. It relies on context like user role, location, device, and requested data to enforce strict access policies, preventing unauthorized access and lateral movement. Establishing a zero trust architecture requires visibility and control over users and encrypted traffic, continuous monitoring and verification of internal traffic, and strong multifactor authentication like biometrics or one-time codes.


Critically, in a zero trust architecture, a resource's network location isn't the biggest factor in its security posture anymore. Instead of rigid network segmentation, your data, workflows, services, and such are protected by micro-segmentation, enabling you to keep them secure anywhere, whether in your data center or in distributed hybrid and multi-cloud environments.

According to Garner, more than 60% of organizations will embrace zero-trust principles as a starting place for security by 2025.

Three Core Principles of Zero Trust

Three Core Principles of Zero Trust

Least Privilege Access

This foundational principle of granting the least privilege necessary to complete your tasks is the core of the Zero Trust model. This careful allocation of privileges is crucial for minimizing the attack surface and limiting the potential damage from security breaches or insider threats.

Always Verify

In the Zero Trust model, the concept of implicit trust is completely abandoned in favor of constant verification. This approach operates under the assumption that a security breach is already present within your system.

Risk Mitigation

To effectively minimize the blast radius within a network, the Zero Trust framework advocates for an 'assume breach' approach. By segmenting the network into smaller, secure zones, this strategy enhances control over access and sharply curtails the possibility for threats to move laterally within the system.

With the rise of cybersecurity threats and remote work, VPNs are becoming obsolete.

With the rise of cybersecurity threats and remote work, VPNs are becoming obsolete.

Historically, organizations have relied on the perimeter defense model, creating a digital "fortress" around their network resources. Within this fortress, everything was considered safe, while everything outside was deemed a threat.


VPNs played a crucial role in this model by extending the perimeter to remote users, but there are several limitations. Learn more by downloading the ZTNA vs VPN guide.

Zero Trust Architecture Explained

How Does Zero Trust Work?

How Does Zero Trust Work?

How Does Zero Trust Work?

As a core concept, zero trust assumes every component or connection is hostile by default, departing from earlier models based on secure network perimeters. This lack of trust is technologically defined by:

The underlying architecture

Zero Trust models used approved IP addresses, ports, granular access controls and remote access VPN for trust validation.

No implicit trust

This considers all traffic as potentially hostile, even that within the network perimeter. Traffic is blocked until validated by specific attributes such as a fingerprint or identity.

Context-aware policies

This stronger security approach remains with the workload regardless of where it communicates—be it a public cloud, hybrid environment, container, or an on-premises network architecture.

Multifactor authentication

Integrate multiple factors like user credentials, unique identity characteristics, familiar devices, and safe geographic locations to provide a comprehensive security layer.

Security for all environments

Protection applies regardless of communication environment, promoting secure cross-network communications without need for architectural changes or policy updates.

Surface area reduction

The number of unnecessary resource access granted to users is directly correlated to the size of the attack surface and the opportunity for lateral movements.

Future Proof Security

What is Zero Trust Network Access?

Zero Trust Network Access (ZTNA) addresses your visibility and risk management challenges head-on by abandoning the outdated trust assumptions of legacy solutions. ZTNA operates on the principle that trust must never be implicit and that verification is required from anyone and anything trying to access resources in your network. This approach fundamentally changes how you manage visibility and risk.

Granular Visibility and Control

ZTNA provides you with detailed insights into who is accessing what resources, from where, and under what conditions. This granular level of visibility ensures that any unauthorized or suspicious activities can be detected and mitigated promptly.

Seamless Management Across Environments

ZTNA solutions are designed to function across your diverse and complex IT ecosystems, offering visibility and control whether resources are hosted on-premises or in the cloud.

Proactive Risk Management

By continuously monitoring network activities, paired with least privilege access, ZTNA enables you to proactively identify and prevent security risks before they escalate into breaches.

Zero Trust Architecture Explained

How to Get Started with Zero Trust

How to Get Started with Zero Trust

How to Get Started with Zero Trust

When designing a zero trust architecture, your security and IT teams should first focus on answering two questions:


  1. What are you trying to protect?

  2. From whom are you trying to protect it?


This strategy will inform the way you design your architecture. Following that, the most effective approach is to layer technologies and processes on top of your strategy, not the other way around.


In its zero trust network access (ZTNA) framework, Gartner recommends leveraging zero trust delivered as a service. You can also take a phased approach, starting with either your most critical assets or a test case of non-critical assets, before implementing zero trust more broadly. Whatever your starting point, an optimal zero trust solution will offer you immediate returns in risk reduction and security control.

Everyone wants to know what product to buy to implement Zero Trust best suited to each organization. The truth is that you won't know the answer to that until you've gone through the process.

Here are the 5 Steps to Implement Zero Trust

Here are the 5 Steps to Implement Zero Trust

1

Define the Protect Surface

Every Zero Trust environment is tailor-made for each protect surface. Until you know what you need to protect and how it works, you wont know the most effective solution. So first Identify what critical data, assets, applications, and services you need to protect.

2

Map the Transaction Flows

Understand how data moves within your organization to design appropriate access policies. There is never a time that any resource on your internal network should go outbound to an unknown server on the internet.

3

Architect Your Zero Trust Network

What protections do you have so far? Assess or reassess your existing solutions within the context of a Zero Trust environment. Implement the necessary technology solutions, such as identity and access management (IAM), multi-factor authentication (MFA), and micro-segmentation tools.

4

Create a Zero Trust Policy

Think about the who, what, where, when and why. Define policies based on user roles, data classification, and context. Only ensure that users have the least privilege access necessary to complete their tasks.

5

Monitor and Maintain

Continuously monitor network activity and adjust policies as needed to address emerging threats and changing business needs. Every security stack should be future proof and a system should be in place to for Continuous Threat Management (CTEM).
