Let’s start where the shoe pinches the most. Micro-segmentation is known to be somewhat challenging in the security world. It is said that the solutions are complex to set up, involve time-consuming work and that user organizations complain about the additional security layer in their daily operations.
There might have been some truth to the talk. Micro-segmentation is a relatively advanced technology to implement, particularly a few years ago when the first products hit the market. Since then, Micro-segmentation solutions have matured, and ongoing efforts have simplified the setup by integrating functionality into the technology.
Introduction to implementation of micro-segmentation in network
Despite its tarnished reputation, our advocacy for using Micro-segmentation persists because the technology holds significant potential. Micro-segmentation is, in many ways, a timely security technology. As businesses become increasingly digital and migrate more workloads, applications, and data to the cloud, the escalating pace of digitization and the desire for more flexible workflows contribute to a growing cyber threat that can instantly undermine a company. All these trends make it challenging for security professionals to construct a security model that meets the company’s needs while simultaneously managing users, devices, and business-critical information.
The ability to construct a contemporary security model is precisely what makes Micro-segmentation a popular technology. It can be part of the solution when the board or top management seeks solutions to elevate IT security to the next level. Micro-segmentation aligns, among other things, with the Zero Trust security paradigm, which involves integrating automated control mechanisms into a company’s security architecture. Instead of building a security architecture based on principles that allow users and devices to move freely within the network, the Zero Trust approach insists on building according to principles that make it difficult or, in some cases, impossible to move freely within the network. This is done to best protect the company against attacks and, if the worst happens, minimize the risk of a cyber attack spreading across the application portfolio.
As stated, we don’t portray ourselves as the consultancy that suggests implementing Micro-segmentation in an organization is a quick and easy task because it’s not. The purpose of this whitepaper is to illustrate how to facilitate a smoother and faster initiation of micro-segmentation. A blueprint for a successful implementation and anchoring process exists, and that’s what we distill here. The white paper outlines seven steps on how to approach the implementation of micro-segmentation, covering:
Where and how does the implementation of micro-segmentation in network begin?
- The methodological and product-related choices your organization needs to make.
- What does Micro-segmentation demand from your organization?
- At what organizational level should micro-segmentation be anchored?
- The competencies required to monitor and respond to incidents.

FAQs about micro-segmentation:
Micro-segmentation is a technical discipline within network security. It allows security architects to divide the data center into logical segments. Specific security controls are defined for each segment to protect the data and applications, making it inaccessible to other segments. This way, any potential data breach in the data center would only affect one segment, minimizing the risk of the attack spreading to other data and applications.
Micro-segmentation aligns with security frameworks such as ISO, NIST, and CIS. For instance, CIS Control 3, focusing on data protection, recommends segmenting networks so that assets with the same classification are in the same segment and separated from assets with a different sensitivity class. If possible, access to each segment should be controlled. The same control point also explicitly states the need to separate applications and storage in the data center.
