In the fast-paced digital environment of today, businesses and institutions confront an array of cyber risks that can jeopardize their sensitive information, disrupt operations, and harm their reputation. Among these hazards, insider threats stand out as a notable danger, emanating from individuals within the organization who possess access to valuable systems and data. Whether intentional or accidental, these insiders have the potential to inflict substantial damage.

To counteract this persistent peril, organizations are progressively adopting the implementation of Zero Trust Network Architecture (ZTNA), a robust cybersecurity framework that provides a comprehensive and proactive strategy for mitigating insider threats. By adopting a Zero Trust approach, organizations can establish a security model grounded in the principle of “never trust, always verify.”

Understanding Insider Threats

Insider threats can emerge from various sources within an organization, including employees, contractors, and even business partners. These threats manifest in different forms, such as data breaches, unauthorized access to sensitive information, and deliberate or inadvertent data leaks. Insiders usually possess legitimate access to critical data and systems, making their detection and prevention challenging. Consequently, organizations must employ advanced security measures to effectively guard against these internal hazards.

Zero Trust Network Architecture: An Overview

Zero Trust Network Architecture (ZTNA) is an advanced security framework built upon the foundational concept of never placing trust without constant verification. Unlike traditional perimeter-based security models that rely on trust within the network, ZTNA adopts a cautious stance by treating every user, device, and application as potentially untrusted, regardless of their physical location. By enforcing rigorous identity verification and access controls, ZTNA ensures that only authorized individuals can gain entry to designated resources. Furthermore, ZTNA places significant emphasis on the principle of least privilege, guaranteeing that users are granted only the necessary access required for their specific tasks. This innovative security framework transforms the way organizations approach network security. By challenging the conventional notion of trust, ZTNA offers a strong defense against potential threats and vulnerabilities.

Mitigating Insider Threats with ZTNA

Precise Access Controls: Zero Trust Network Access (ZTNA) enforces meticulous access controls tailored to individual roles, ensuring that employees are granted access solely to the resources essential for their job functions. This approach effectively reduces the risk of employees inadvertently encountering sensitive data beyond the scope of their authorized access privileges. By strictly adhering to this principle, organizations can uphold a robust security posture and protect their valuable information assets.

  • Micro-Segmentation: Zero Trust Network Access (ZTNA) divides the network into smaller, distinct segments, significantly impeding the ability of malicious insiders to move laterally within the network. Even if an unauthorized insider breaches one segment, their ability to traverse the network is severely restricted. This robust security measure ensures that even if an insider gains access to a specific segment, their capability to navigate the entire network is effectively limited.
  • Continuous Monitoring and Authentication: Zero Trust Network Access (ZTNA) mandates continuous monitoring and multi-factor authentication (MFA) to verify user identities. This robust security measure ensures that only authorized individuals can access valuable resources while their actions are constantly monitored for signs of suspicious activity. By embracing ZTNA, organizations can bolster their security posture and defend against potential threats.
  • Behavioral Analytics: ZTNA employs behavioral analytics to identify unusual user behavior patterns. If an insider’s behavior deviates from the norm, the system triggers alerts and takes immediate action to prevent potential threats.
  • Secured Remote Access: With the rise of remote work, ZTNA proves particularly valuable in securing remote access to an organization’s resources. It ensures that remote employees adhere to the same security standards as on-site personnel, reducing the risk of insider threats originating from remote locations.
  • Data Loss Prevention (DLP): Zero Trust Network Access (ZTNA) seamlessly integrates with Data Loss Prevention (DLP) solutions, thwarting unauthorized data transfers or leaks. This pivotal feature strengthens the security of sensitive information, shielding it from both deliberate and inadvertent insider threats. This integration empowers businesses to proactively identify and prevent any unauthorized attempts to transfer or disclose sensitive information, thereby mitigating the risk of data breaches and potential reputational damage.

Industry Facts:

  • Growing Insider Threat Landscape: According to various industry reports, insider threats are on the rise. A report by the Ponemon Institute revealed that insider threats constituted 60% of all cyber attacks in 2020, highlighting the significance of this threat vector.
  • Variety of Insider Motivations: Insider threats can stem from a variety of motivations, including financial gain, personal grievances, espionage, and unintentional errors. This diversity in motivations makes detecting and mitigating insider threats even more challenging.
  • Impacts of Insider Threats: The impacts of insider threats can be devastating. The 2020 Cost of Insider Threats Global Report estimated that the average cost of an insider-related incident was around $11.45 million for companies surveyed, including both direct and indirect costs.
  • Regulatory and Compliance Pressure: Industries that handle sensitive data, such as healthcare and finance, are subject to stringent regulatory requirements for protecting customer information. Failing to secure data from insider threats can lead to substantial fines and legal consequences.

Implementing Zero Trust Network Architecture:

  • Zero Trust Adoption: The adoption of Zero Trust Network Architecture (ZTNA) is gaining momentum across industries. A Gartner survey predicted that by 2023, 60% of enterprises will have phased out their remote access virtual private networks (VPNs) in favor of ZTNA.
  • Remote Work Acceleration: The rapid shift to remote work due to global events like the COVID-19 pandemic has accelerated the need for robust remote access security. ZTNA’s principles align well with securing remote work environments, ensuring that users and devices are verified before accessing sensitive resources.
  • Behavioral Analytics on the Rise: Insider threat detection mechanisms are becoming more sophisticated. Behavioral analytics, which involve monitoring user activity for deviations from normal patterns, are being increasingly integrated into security frameworks like ZTNA to identify potentially malicious actions.
  • Vendor and Partner Ecosystems: Insider threats aren’t limited to employees; they can extend to third-party vendors and partners with access to an organization’s systems. ZTNA’s approach of verifying every user, device, and application aligns with the need to secure these extended ecosystems.
  • Investment in Cybersecurity: Organizations are increasing their cybersecurity investments in response to the growing threat landscape. A report by Cybersecurity Ventures projected that global spending on cybersecurity products and services would exceed $1 trillion cumulatively from 2017 to 2022.


Insider threats continue to be a critical concern for organizations across industries. The adoption of Zero Trust Network Architecture (ZTNA) presents a proactive approach to mitigating these threats. By adhering to the principle of “never trust, always verify,” ZTNA helps organizations establish strong defenses against insider-related risks. This approach emphasizes stringent access controls, continuous monitoring, and behavioral analytics, providing a robust and multi-layered defense mechanism against insider threats.

As the cybersecurity landscape evolves, organizations must proactively adopt innovative approaches like ZTNA to protect their valuable assets and maintain stakeholder trust.

ZTNA – Zero Trust Network Architecture is also known as software defined perimeter (SDP). It includes the solutions that are implemented by an organization to give its employees access to only those resources that are used by them. This reduces the risk of a possible cyber attack or data leakage issue for the organization.

The ZTNA solution identifies the authenticity of the user and links the identity to their collection of roles defined within the organization.

The access controls within the ZTNA solution ensure that all traffic passing through the organization’s network go through the ZTNA solution for enhanced security.

With the flexible working environment being introduced post-pandemic, it has become inevitable for organizations to choose an approach that offers scalability and agility to secure the distributed workforce. 

Benefits of ZTNA implementation within organizations

The Zero Trust Network Access solution can be implemented within the organization through a set of use cases that are specific to every individual organization.

These use cases are implemented within the organization based on their functionality and network usage.

  • Secure Remote Access: VPNs are used by most of the organizations to support a remote workforce. The major drawback of VPNs is that they provide access to the complete network to an authenticated user. Through the effective use of ZTNA solutions the accessibility of remote workers can be restricted to only a few functionalities of the network that are necessary for accomplishing their jobs.
  • Secure Cloud Access : The use of a cloud infrastructure is increasing as many enterprises have realized the multiple benefits of cloud storage solutions. It is necessary for organizations to limit the access of cloud-based resources for a secure and intrusion free network.

Reduce the risk of a possible intrusion

The most common goal of intrusion for cybercriminals is through a compromised account. A user account that has been compromised allows an attacker to move through the organization network and access multiple resources thereby leading to potential damages. Implementation of ZTNA helps to minimize the intruder’s access level and reduce the amount of damage caused to the resources. 

Ways to implement ZTNA within an organization

ZTNA solution can be implemented within an organization through the following ways:

  • Gateway Integration: ZTNA can be implemented within the network as part of the network gateway access policy. The traffic entering the network is filtered based on the permissions and the access control policies. Any user attempting to access the network needs to have authentication for using the various resources within the organization.
  • Secure SD-WAN: SD-WAN within an organization is used to implement optimized networking access within the organizational WAN. Secure SD-WAN is used to integrate a secure stack into each appliance within the network. Implementation of ZTNA into this SD-WAN stack helps to provide a centralized access management within the organization.
  • Secure Access Service Edge (SASE): The SASE functionality includes making the SD-WAN functionality available as a virtual appliance in the cloud. It helps organizations to maximize both network efficiency and security, including ZTNA functionality.


Implementing ZTNA within an organization helps reduce the risk of cyberattacks. Allowing employees with limited access to resources based on their roles and responsibilities helps reduce the damage caused by potential intruders or a malicious insider.
