The Comprehensive Guide to Cyber Ranges


From an often ignored IT issue to becoming a boardroom priority, the role of cybersecurity has changed dramatically in the past few years. In the wake of high-profile data breaches, increased regulatory, compliance, and cyber insurance requirements—and the brand damage impact on company valuation—it’s no wonder the game has changed. 

In most cases, good cybersecurity can avoid these issues and lower the cost of cyber insurance premiums for organizations that can demonstrate and quantify security teams’ capabilities, processes, and technology.

For these reasons and more, business leaders and security professionals are looking for every advantage they can get when securing their brand reputations and their customers’ data.

There are undoubtedly many tools, best practices, and training programs that organizations can use to improve their security posture, optimize their technology stack, and dial in their incident response. Each of these security components must work in harmony, to achieve the results security professionals and organizations require to react effectively to real-world threat events. 

Fortunately, as threats have evolved, so have the resources available for organizations to fight back.

One of the most efficient and cost-effective ways to optimize your security teams and overall security posture is integrating a cyber range into a comprehensive security readiness program. But just what is a cyber range and how can your organization use it to your advantage?

Chapter 1

What is a cyber range?

Cyber ranges are high-fidelity, simulated environments where security professionals can train, test, and practice responding to different security scenarios and experiment with security configurations, tools, and products to adjust to the latest security attacks.

For example, cyber ranges are currently being used to

  • Test security stacks and configurations
  • Ensure security policies are being used and enforced.
  • Provide live attack scenarios to train and assess teams and individuals.
  • Provide evidence for compliance with regulatory requirements and security frameworks.
  • Synchronize incident response across people, processes and technology
  • Help security vendors test and develop new products.

A cyber range is made up of a platform that creates a high-fidelity clone of production IT and OT environments, including:

  • Servers
  • Applications, 
  • Cloud instances and servers
  • Networking and IoT devices
  • Security stack products
  • Open-source tools


A fully configured cyber range allows organizations to deploy specific and measurable training red/blue/purple team training scenarios, validate the effectiveness of their security stack, and confirm their processes will be capable of repelling the latest security requirements and ensure compliance.

Chapter 2

Why do organizations use cyber ranges?

The simple reason that organizations deploy ranges is to increase, quantify, and validate cyber readiness and provide evidence of compliance for a wide variety of regulatory demands.

Cyber ranges deploy a selection of testing and training capabilities to enable your security, risk, and vendor management teams to meet the objectives of your business or mission. From helping your team evaluate new tools to measuring staff readiness to pitting your defenses against specific attack scenarios, cyber ranges can be molded to fit your organization’s exact objectives and reporting requirements.

Increase enterprise readiness.

As any security leader knows, all employees across an enterprise must participate in maintaining cybersecurity. Modern cyber ranges can help with these learning and development situations, too.

In fact, simulations can be tailored to fit any industry’s operational environment and be used as part of larger organizational training exercises. For example, executives can practice how they handle media relations, interactions with law enforcement, internal communications, key technical decisions, and business risks. 

In other situations, employees in other functions, such as finance or human resources, can practice how they would respond to phishing emails or updates from security team members to help thwart an attempted attack.

The lessons learned from these simulations can allow your organization to improve how your business units, managers, and security teams respond to attacks in a coordinated way.

Optimize security processes and technology stack.  

Sometimes building and validating a security stack can feel like strategically stacking slices of Swiss cheese and hoping you've covered all the holes. Cyber ranges allow you to test, adjust, stress, and validate your security stack and your existing incident response plans, thereby creating a higher level of security readiness.

To start, organizations can stress-test how existing defenses in their current network environment withstand the pressure of a real attack, how quickly incident detection systems are triggered, and what responses your team initiate. In other situations, an organization can build on its setup with minor modifications or major changes to test how its attack surface changes. 

Evaluate security stacks.

One of the most crucial responsibilities for every security team is choosing which products will make up their organization's security stack.

The decision to invest in and deploy a new security tool can be complex and have many known and unknown downstream impacts. Advanced cyber ranges give your security team the ability to evaluate products, test new patches before they go into production, and monitor them during operation. Cyber ranges give you the ability to know how they will perform and interact with the rest of your current security portfolio. 

Instead of discovering issues after you buy a new tool, you can test out the product in the safety of a cyber range instead of your live environment—all before you buy. 

Replicate attack scenarios.

Cyber ranges allow your organization to simulate any cyberattack scenario your infrastructure can face. In these simulations, security professionals can fully practice their incident response playbooks and go beyond gamification exercises to see how they react when faced with a real threat. 

As cyber range events continue to evolve, your team can immediately apply what they have learned, refine the configurations of their security tools and response protocols, and improve response plans until your incident response team is as ready as it can be.


Provide evidence for compliance.

There are thousands of regulatory and compliance requirements for organizations to follow. They tend to be in four groups:

  • General: From the ubiquitous SOC 2 report for public companies to requirements for publicly traded businesses and even those required of government agencies and educational institutions, an organization must prove that basic security capabilities and best practices are in place.

  • Data Privacy: Across the globe, GDPR, CPPA, CCPA, and many others set strict standards for data privacy and user control of data. To comply with these requirements, organizations must have stringent security practices and data management processes in place.

  • Operational and VRM: The most common examples are ISO 27001 and the U.S. Department of Defense’s CMMC. These and other operational and supply chain standards require that security teams have their security model independently assessed to prove that they can meet the requirements to be a vendor.

  • Industry-Specific: Each industry has its specific compliance requirements that govern how businesses secure and manage data as well as system and network access. For example, financial firms must support PCI DSS and FFIEC, while healthcare organizations must comply with HIPAA and HITRUST.

Cyber ranges provide a comprehensive method to validate that you can meet these requirements.

Provide analytics and reporting required for security measurement.

All security leaders have to report on the state of their security programs, including the people, processes, and technology involved. Sometimes, this is in deep analytics using tools like Splunk, or workforces readiness tools like Workday, or high-level reports for executives and board members. Cyber ranges can provide these core data and required metrics and confirm that the data being captured is accurate and comprehensive.

Evaluate potential hires.

Formal training and certifications in cybersecurity, networking, and computer science provide a solid foundation for any security professional, but organizations often need their new hire to hit the ground running. Cyber ranges are the perfect proving ground for these purposes.

For example, you can build candidate assessments that present different scenarios in a cyber range to evaluate how an applicant reacts, measure their skillset in different security or networking tools, or see how well they can communicate technical topics in operational terms.

You can also use cyber ranges to evaluate your existing team’s strengths and weaknesses in different technical domains. You can then use the results to create personalized training plans for continuous improvement and professional development.

Chapter 3

What are the different cyber range delivery models?

As with other technology solutions today, organizations have options when it comes to how they can create, manage, and leverage their cyber range.

Based on its budget, its training and testing needs, and the resources it has available to administer a cyber range, an organization can choose either an on-premises deployment or one that is cloud-based.

On-Premises Deployment

On-premises implementations give organizations the ability to create and use a cyber range exactly as they choose. Whether by using their own equipment and technology to design a cyber range or by leveraging a cyber range platform provided by a leading industry provider, organizations can segregate their cyber range training and testing environments in their own private cloud or in-house hosted infrastructure.

The administration of an on-premises deployment can be more complex, but the security of knowing the cyber range is hosted internally (or even completely air-gapped) can be worth it.


Cloud-Based Deployment

Like other as-a-service offerings, a cloud-hosted cyber range provides flexible, easily reconfigurable, and cost-effective infrastructure for organizations that need it, without all of the responsibility for management and maintenance put on internal staff.

Choosing this model means having access to advanced training and testing environments in an isolated, safe, and controlled environment that is scalable based on needs and budget.

Similarly, an organization can choose to host its cyber range in an existing cloud infrastructure, deploying and managing it like other on-demand services.

Chapter 4

How does a cyber range simulation work?

The great thing about a cyber range is that it can be set up, used, reset, and rerun as many times and in as many different configurations as needed, all while keeping your production systems safe.

Every scenario or simulation will be different, but the lifecycle of a cyber range simulation generally follows a set pattern. 

Common steps include:

  • Establishing objectives: Whether it is a one-off training event, a candidate evaluation, or a simulation, establishing the objectives for the exercise is vital for identifying the people, processes, technology, and analytics required to measure success and prepare the environment.

  • Building out the infrastructure: Based on the goals and objectives established, identify the number and type of servers and clients needed, the security tools to deploy, and the interfaces and networking to accurately create the cyber range environment.

    At this stage, partnering with a trusted cyber range provider can make the process more efficient. Your team can select from a number of pre-existing scenarios, which include the defensive and offensive elements of the exercise as well as simulated “regular” network activity.

  • Configuration: Next, security tools, clients, servers, and network devices are configured to match the requirements of the scenario, which could include replication of an actual production environment or one that is slightly modified to test the impact of certain changes. 

  • Prepping the scenario: This involves preparing the cyber range event participants for the scenario they are about to be a part of and the attack or test cases. For example, this could include loading up the elements needed to replicate a(n):
    • Malware attack
    • Natural weather event
    • Distributed denial of service (DDoS) attack
    • Insider threat
    • Ransomware attack
    • Training scenarios or cyber range evaluations
    • Advanced persistent threat (APT) situation
    • Red team versus blue team challenge
    • Blended purple team training scenario
  • Documenting and measuring results: Once the scenario is underway, documentation of key actions, outcomes, and events is key to conducting a productive debrief of the event. These key lessons learned and areas for improvement can be used for the next phase of training or evaluation.

    Or, in the case of a candidate assessment, the results of the cyber range scenario can be joined with other elements of the interview process to help organizations make a more informed decision.

  • Resetting and repeating: A key capability of a cyber range is its versatility. As soon as the cyber range event is done, teams can shut off specific virtualized systems, change configurations, and deploy new scenarios quickly and easily. This allows teams to refine their responses or ramp up the pressure for continuous improvement.
