The idea of a cybersecurity mesh as the way forward in this evolving digital landscape isn’t new. In fact, several security providers have been providing comprehensive and consolidated security solutions over the last few years based on the cybersecurity mesh approach including the Fortinet Security Fabric, Checkpoint Security Infinity, and Arhamsoft

However, the concept gained traction when Gartner tagged it as a top strategic technology trend in 2022. The firm noted that the rapid evolution and sophistication of cyberattacks in tandem with organizations migrating to hybrid multicloud systems creates a “perfect storm” of security risk that needs to be addressed. 

What is Cybersecurity Mesh Architecture?

As described by the firm, a Cybersecurity Mesh Artchitecture (CSMA) is a “composable and scalable approach to extending security controls, even to widely distributed assets”. This approach is said to be incredibly suitable for modular networks that are consistent with hybrid multi-cloud architectures. 

In traditional cybersecurity approaches, security controls are typically implemented at the network perimeter or within specific devices or applications. However, as organizations and their digital ecosystems become more complex and distributed, this perimeter-centric approach becomes less effective.

Cybersecurity mesh takes a more adaptive and dynamic approach. It envisions a security framework where security controls are woven into every aspect of the digital environment, forming a “mesh” of interconnected security services and capabilities. This approach allows for more granular and context-aware security, enabling protection at various layers, from individual devices and endpoints to applications and data.

Key features and principles of cybersecurity mesh architecture include:

  • Distributed and pervasive security: Security controls are distributed across multiple components and devices, extending protection beyond the traditional perimeter.
  • Identity-centric security: The focus is on securing individual identities and devices, rather than just protecting the network as a whole. This approach helps mitigate risks associated with unauthorized access and compromised credentials.
  • Dynamic and adaptive security: The mesh adapts to the changing security landscape and evolving threats, adjusting security controls based on real-time risk assessments and contextual information.
  • Scalability and flexibility: The cybersecurity mesh architecture allows for scalable deployment and integration of various security solutions, accommodating the diverse needs of modern digital environments.
  • Interoperability: Cybersecurity mesh promotes interoperability between different security technologies and services, enabling seamless communication and collaboration between them.

By adopting this cyber mesh architecture, organizations can achieve a more resilient and responsive security posture. It helps address the challenges posed by distributed architectures, cloud services, IoT devices, and the increasing sophistication of cyber threats.


Cybersecurity Mesh Architecture: Overview

In essence, each tool in the IT infrastructure within the CSMA operates as a cog in a greater machine. The framework proposed by Gartner is based on four layers: 

  1. Security analysis and intelligence: which analyses past cybersecurity attacks, as well as data and lessons from other tools, to inform future trigger responses and actions 
  1. Distributed identity fabric: a decentralization of identity management, identity proofing and entitlement management, creating an environment of adaptive access 
  1. Consolidated policy and posture management: the ability to translate central policy into native configuration of each individual security tool 
  1. Consolidated dashboards: offering a holistic view of the entire security ecosystem 

The CSMA framework appears to offer significant benefits over the traditional IT security model. 




Fortinet highlights the benefits of cybersecurity mesh, emphasizing that CSMA is poised to help organizations transition from obsolete legacy security systems to an integrated cybersecurity approach. This integration is vital as it enhances security, promotes operability among different security tools, and fosters agility.

This novel approach offers several crucial benefits, according to cybersecurity providers. 


Responsive Security 


The intelligent security design of a CSMA increases the agility and resilience of an organization’s security setup. With security tools working together on the same standards of zero trust, this approach ensures that an organization’s network receives the best real-time defense against known and evolving threats.  

A cybersecurity mesh is better able to handle more IAM (identity access management) requests, allowing for more mobile, adaptive, and unified access management. This means an organization will have a more reliable approach to managing access and control of its digital assets that is more spread out now than ever before.

This is especially significant as IBM reported that companies with a workforce that is more than 50% remote took 58 days longer to identify and contain breaches than those with less than 50% remote employees.  


Improved collaboration 


CSMA extends security across the entire organizational network while allowing IT departments to secure all systems and access points with a single set of interoperating tools and technologies.  

With the shift towards hybrid cloud solutions and remote work, organizations are making efforts to not only integrate third-party applications and services but also to ensure that those technologies are appropriately secure. 

This setup also improved the speed and efficacy of threat detection, and consequently response and prevention strategies as well. The information gathered by each security tool can be leveraged within the ecosystem to quickly address each security threat that may crop up. 


Flexibility and Scalability 


A key feature of CSMA is its distributed nature, creating individual security perimeters around each access point within an entire network and ecosystem. What this allows is deep visibility of the network edges, ensuring that all areas are protected in equal measure.  

The flexibility that this creates in a security system also gives organizations more agility to build new IT infrastructure and introduce new solutions as needed without compromising protection. An IT department is better able to keep up with the evolution of expanding and distributed IT infrastructure within the CSMA. 


Redefined cybersecurity perimeter 


Switching from the traditional “walled city” approach of cybersecurity where a perimeter is set up around the network may have been effective when it was first introduced. However, now that applications, data, devices, and users are operating outside of the traditional data centers and offices, CSMA becomes vital. 

The redefined cybersecurity perimeter that is key in the CSMA reduces the time taken to deploy security measures and responses as it offers a distributed identity fabric that establishes trusted access at each entry point into the network.  

On that note, CSMA is also expected to reduce insider threat incidents according to Gartner. These include credential thefts and attacks by malicious insiders which can cost organizations about $15.38 million per incident.

There has been an increase in the frequency of insider threats from 60% in 2020 to 67% in 2022, in part due to the dramatic shift to remote and hybrid working as well as the “Great Resignation”. People are leaving organizations but still have access to critical data, systems, and infrastructure within the organization – this creates more vulnerabilities. 

The CSMA approach of building new perimeters and layered defenses around each device and network access point could make all the difference in mitigating this issue.  


Simplified Deployment and Management 


The agility of a CSMA also benefits organizations by making it easier and quicker for security teams to deploy and configure new solutions. Gartner’s proposed consolidated dashboard, which makes up one of the layers of CSMA, would enable organizations to better adapt their security structure to meet evolving business and security needs.  

An integrated security architecture would remove the need for security teams to switch between and operate various tools, which takes up precious time. Instead, it frees them up to focus on deploying and configuring solutions and frees them up for other critical security tasks, thereby improving efficiency overall. 


Challenges of CSMA 


While the benefits are many, totally overhauling the approach to security can pose several challenges. 

Some key challenges include:  

Ensuring proper training and support 

This is a relatively new framework and implementing it requires a significant change in the mindset. Organizations that want to build a CSMA will have to make significant investments in ensuring that their IT personnel are prepared and well supported during the transition.  

Ensuring secure and simple identity-based system 

A key aspect of CSMA, as mentioned before, is the newly defined security perimeter. Organizations will have to ensure that users are able to securely and easily access the network without it being a distraction that would lead to reduced productivity.  

Difficult and costly to apply to an existing ecosystem 

The CSMA would be much easier to incorporate during the planning stage of a security ecosystem, conducting discussions and reviews of security procedures with cloud and platform providers. Organizations that are looking to make this shift with an existing ecosystem may find it more challenging to do so. 

Cybersecurity mesh is at the core of zero trust philosophy. This shift in mindset required to make the shift could pose a significant hurdle, not to mention the cost that it might incur to implement a system based on this approach. 

Though the CSMA seems to bring with it many benefits, the challenges of making such a major shift in the security framework remain. Despite that, will CISOs and security leaders make the leap?
