What is Zero Trust Security?

An ever-evolving IT environment and cyber-threat landscape have made legacy security infrastructures ineffective. Based on the outdated assumption that anything within the security perimeter can be trusted, they leave organizations exposed to cyber attacks.

Across the industry, security professionals are designing and rebuilding their strategies around a Zero Trust approach, one that trusts no user, device, or system, neither inside nor outside the perimeter.

What is Zero Trust Security? Types of Zero Trust Principles

The Evolution of Remote Work

Today, you no longer have to set foot in the office building to come to work. Advancements in technology have expanded what is now classified as “the office,” with companies able to interface through mobile devices and cloud software regardless of where their employees are located.

However, these developments pose a cybersecurity dilemma. The security perimeter is no longer confined to the walls of an office building. Valuable business data transfer continuously between SaaS applications, IaaS, data centers, remote users, IoT devices, and more. This means cyber-criminals have access to broader attack surfaces and more entry points than ever before. As evidence, in 2018, 34% of cyber-attacks were perpetrated by insiders1.

To complicate matters even more, once these cyber-criminals are inside your perimeter, they seek and steal valuable and sensitive data for months before being detected. In fact, in most cases, it takes six months to detect a data breach.

Alarmingly, most incumbent security infrastructures are generationally outdated and dangerously behind the level of attacks they must protect against. Clearly, it’s time for a new security paradigm.

The Zero Trust Security Approach: Never Trust, Always Verify!

Across the industry, security professionals are shifting to a Zero Trust Security state-of-mind: No device, user, workload or system should be trusted by default, regardless the location in which it is operating from, neither inside or outside the security perimeter.

But Zero Trust is more than just a concept. The Zero Trust Extended Security model, introduced by Forrester analysts, offers seven essential principles of implementation that organizations should focus on when moving toward a Zero Trust security model. Implementing these principles enables the adoption of a security posture of “Default Deny” where systems are hardened and isolated until a level of trust is established

Types of Zero Trust Principles

Let’s see what each of the zero trust security principles means:


When moving toward Zero Trust Security, it is crucial you “Divide and Rule” your network. Identifying your valuable assets and defining “Micro-segments” around them create multiple junctions and inspection points that block malicious or unauthorized lateral movement, so that the threat is easily contained and isolated in the event of a breach.


Securing workloads, particularly those that are running in the public cloud, is essential since these cloud assets (e.g., containers, functions, and VMs) are vulnerable and attractive targets to malicious actors.


Zero Trust is all about protecting the data while it is shared continuously between workstations, mobile devices, application servers, databases, SaaS applications, and across the corporate and public networks.


With 81% of data breaches involving stolen credentials2, it is clear that username and passwords no longer prove the identity of a user. Identities are easily compromised, so access control to your valuable assets must be strengthened.


With 70% of breaches involving compromised devices1, every device connected to your network should be treated as a threat vector, whether it’s a workstation, a mobile, or an IoT/OT device. Security teams must be able to secure every device on their network and isolate it if compromised.


You can’t protect what you can’t see or understand. A Zero Trust Security model continually monitors, logs, correlates, and analyzes every activity across your network.


A Zero Trust Security architecture must automatically integrate with the organization’s broader IT environment to enable speed and agility, improved incident response, policy accuracy, and task delegations.

Deploying Zero Trust Security

There’s a common misconception that achieving Zero Trust is expensive and complex. However, it doesn’t have to be. It can be designed in such a way that it works with your existing architecture. But you have to follow an orderly plan of implementation and execution. This involves five major steps:

  1.     Identify your protect surface
  2.     Map out the transaction flows
  3.     Construct a proprietary Zero Trust architecture
  4.     Develop a unique Zero Trust policy
  5.     Monitor and maintain the system (optimizing over time)

Obviously each of these five stages can be broken down into dozens of smaller action steps, but it’s helpful to organize them according to these headings. If nothing else, this will streamline your approach.

The concept of implementing Zero Trust may still seem foreign, but you don’t have to do it alone. Check Point can help you get there with the industry’s first Zero Trust security workshop. Here, experts will review your existing security architecture, customize a Zero Trust strategy for your business needs, create a detailed implementation plan and blueprint, and provide recommendations for operational efficiency and cost reductions.

Zero Trust Security with Check Point

Implementing Zero Trust using disparate technologies may result in inherent security gaps and complexities. That is why Check Point now offers a holistic and practical approach to implementing Zero Trust based on Check Point Infinity, a consolidated security architecture.

Absolute Zero Trust Security is the Check Point interpretation of the Zero Trust security. Check Point Infinity offers a complete, efficient, and preventive implementation of the Zero Trust security model, enabling organizations to:

  1. Implement all of the Zero Trust security principles: The Check Point Infinity architecture consolidates a wide range of security functions and solutions that will allow you to implement the Extended Zero Trust Security Model.
  2. Efficiently manage Zero Trust using centralized security management and a unified policy- resulting in a 50 percent reduction in security person-hours.
  3. Empower Zero Trust with Real-Time Threat Prevention, focusing on threat prevention and protecting against Zero-day attacks.
