Your guide to vulnerability prioritisation: What it is and why it matters

It’s easy to find vulnerabilities in your organisation; today, there are many great tools available that can help you find them. It is what you do with your findings that really matters. 

Most end up on the mountain of technical debt or a risk register, never to be seen again. Many of the tools and frameworks provide a generic rating of the severity of the vulnerability. You also have limited resources and time to patch or remediate even the critical vulnerabilities; there is always an opportunity cost associated. So, where do you start?

This is where vulnerability prioritisation comes in; it is an excellent first step to understanding the immediate cyber risk in your business. This blog covers the basics of vulnerability prioritisation, including the benefits it brings to your cyber security strategy. 

What is vulnerability prioritisation?

Vulnerability prioritisation identifies, evaluates, and ranks the security weaknesses in a system or network to address the most dire issues first. The process involves assessing the potential impact of each vulnerability, the likelihood of its exploitation, and the resources needed to fix it.

Think of it like triage in a hospital emergency room. Doctors prioritise which patients to treat first based on the severity of their injuries. Similarly, vulnerability prioritisation helps you identify and prioritise the vulnerabilities in your business that pose the greatest threat so that you can address them first.

By prioritising vulnerabilities, your organisation can allocate resources more effectively, focusing on high-risk weaknesses first to maximise overall security. Without a structured approach to prioritisation, it can be challenging to determine which weaknesses demand immediate attention and which can be dealt with later. Vulnerability prioritisation guides this decision-making process, enabling your business to make informed choices about allocating time and resources.

Vulnerability prioritisation can:

Inform decision-making

Identifying, evaluating, and prioritising vulnerabilities gives you the insight to allocate resources effectively, focus on critical threats, and strengthen your security posture.

Risk assessment and management are integral to vulnerability prioritisation. When you engage with a cyber security provider, they will conduct a risk assessment to understand the gaps and potential consequences. So you can make informed decisions about your next steps and the risk management strategies you will leverage.

Reduce cyber security costs

Gartner has forecasted that global security and risk management spending will increase by 11.3% this year. So, as more of us spend on cyber security, keeping costs low is imperative.

Vulnerability prioritisation plays a vital role in cost reduction by minimising the expenses associated with cyber security. It enables you to allocate resources efficiently by first focusing on the most significant threats. Optimising resource allocation improves security posture and allows your organisation to resolve high-impact areas, even on a tight budget.

Streamline IT operations

Vulnerability prioritisation simplifies and optimises IT processes by providing a structured approach to identifying and addressing security weaknesses. Focusing on critical vulnerabilities ensures IT teams direct efforts towards the most significant impact areas, contributing to a streamlined and optimised IT environment.

Providing a clear roadmap for addressing security weaknesses enables IT teams to focus on areas with the most significant impact, maintaining a secure environment and contributing to a streamlined, optimised IT operation, ultimately supporting long-term growth and success.

Maintain compliance with regulations

Prioritising vulnerabilities based on potential impact and likelihood of exploitation ensures timely remediation as required by regulatory bodies like GDPR, APRA CPS234 and PCI DSS. This structured approach demonstrates your company’s commitment to protecting sensitive data and maintaining a secure environment, which is often crucial for regulatory compliance.

Non-compliance can result in severe consequences, such as financial penalties, reputational damage, and legal consequences. Vulnerability prioritisation is essential for maintaining compliance and avoiding these issues. By addressing the most critical vulnerabilities, your organisation demonstrates a commitment to security, minimising the risk of non-compliance and associated penalties.

Enable business continuity

Vulnerability prioritisation highlights opportunities to improve business continuity should you experience a cyber attack. Addressing high-priority vulnerabilities reduces the likelihood of successful attacks so that you can maintain business continuity.

Vulnerability prioritisation informs disaster recovery planning by highlighting your most significant risks. With these insights, you can minimise incident impact and build a resilient organisation with an increased chance of maintaining operations.

Increase customer confidence

A secure and trustworthy environment is vital for customers entrusting sensitive information to your business. Prioritising cyber security demonstrates a commitment to protecting customer data and maintaining a safe online experience. With data breaches and cyber attacks becoming more sophisticated, a robust cyber security posture is crucial in building customer trust.

Vulnerability prioritisation builds trust by addressing critical security weaknesses. Proactively identifying and remediating high-risk vulnerabilities reduces successful cyber attacks, protecting customer data and maintaining a secure digital environment. This commitment to cyber security reassures customers that your company treats sensitive data with care.


Vulnerability prioritisation is an excellent starting point for organisations planning to enhance their cyber security posture. By taking a structured approach, your business can effectively address the most critical risks and create a robust and resilient security strategy.

Vulnerability prioritisation addresses current risks and paves the way for a more secure future and long-term growth. It enables you to proactively identify and remediate vulnerabilities, reducing the likelihood of breaches, financial losses and reputational damage.
