What is a Crown Jewel in Cyber Security?

A crown jewel in cyber security refers to an organization’s most valuable information assets, systems, applications, or services that require the highest level of protection. Crown jewel cyber security focuses on identifying these critical assets so organizations can prioritize security controls, reduce business risk, and strengthen resilience against cyberattacks. Because attackers often target high-value assets, protecting crown jewels is a fundamental part of risk management and cybersecurity strategy.

Why do organizations identify crown jewels?

Not every asset carries the same level of business or security risk. Some systems directly support revenue, intellectual property, customer trust, regulatory obligations, or critical operations.

Organizations identify crown jewels to:

• Prioritize security investments
• Reduce business risk
• Protect critical information
• Improve incident response planning
• Support business continuity

This approach helps security teams focus resources where they have the greatest impact.

How do organizations identify crown jewels?

Organizations evaluate assets based on their importance to business operations, the sensitivity of the information they contain, and the potential consequences of compromise.

A typical process includes:

• Inventorying critical assets
• Assessing business value
• Evaluating cyber risks
• Identifying dependencies
• Applying appropriate security controls
• Reviewing asset criticality regularly

This process helps organizations align cybersecurity priorities with business objectives.

Which assets are commonly considered crown jewels?

Crown jewels vary between organizations depending on their industry, operations, and regulatory requirements.

Organizations typically apply stronger security controls to these high-value assets.

How can organizations protect their crown jewels?

Protecting critical assets requires multiple layers of security rather than relying on a single control. Common protective measures include:

• Applying least privilege access
• Implementing strong authentication
• Encrypting sensitive information
• Monitoring high-value assets
• Segmenting critical systems
• Conducting regular risk assessments

These controls help reduce the likelihood and impact of attacks targeting essential business assets.

Supporting protection for critical assets

Protecting crown jewels requires continuous visibility into the endpoints that access critical systems. Organizations should ensure that managed devices remain compliant with security policies and that security teams can quickly investigate suspicious activity involving high-value assets.

Hexnode can support these operational needs through:

• Device compliance monitoring
• Security policy enforcement
• Access-related configurations
• Centralized visibility into managed endpoints
• Hexnode XDR workflows for endpoint investigations involving critical assets

These capabilities help organizations strengthen endpoint security around their most valuable business resources.
