The challenge of managing the patching process in-house, combined with the costs of hiring in-house staff, can leave many organizations feeling overwhelmed and at risk.
Organizations of all sizes face the risk of unpatched vulnerabilities impacting their security.
From small businesses to large enterprises, every company is at risk of a cyber attack if vulnerabilities are left unpatched.
The average time to patch a critical or high vulnerability is 90 to 180 days.
The consequences of not properly managing vulnerabilities can be devastating; with two-thirds of small and medium-sized businesses (SMBs) going out of business after suffering a major cyber attack.
To sum it up:
Organizations choosing to scan and patch once per month are choosing to accept the risk of a vulnerability compromising their systems for the other 29 days.

What Is Patch Management?
Patch management refers to the process of identifying, acquiring, testing, and installing software updates (also known as patches) to an organization’s systems. These patches aim to fix vulnerabilities and improve the overall security posture of the system.
As part of a comprehensive security program, organizations must manage vulnerabilities to prevent cyber attacks and protect sensitive data.
The Benefits Of A Patch Management
- The first benefit of having a patch management program is that it helps to improve an organization’s security posture. By staying up-to-date with the latest patches, an organization can reduce its exposure to vulnerabilities and lower its risk of a data breach. Regularly applying patches ensures that an organization’s systems and applications are secure from known threats.
- The second benefit is that a patch management program is cost-effective compared to the cost of a data breach. The cost of a data breach can be significant, including not just the cost of restoring systems and data but also the loss of business and damage to an organization’s reputation. Investing in a patch management program helps to prevent a data breach and reduces the overall cost of managing risk.
- Finally, a patch management program can help organizations comply with regulatory requirements. Many regulations, such as the GDPR and HIPAA, require organizations to implement security measures to protect sensitive data. A formal patch management program demonstrates that an organization is taking its security responsibilities seriously and helps to ensure compliance with these regulations.
How The Patch Management Process Works
Patch management is a step in a vulnerability management program.
Vulnerability management is a holistic approach to managing cyber risk and encompasses the entire lifecycle of a vulnerability.
The goal of patch management is to keep software and systems:
- Up-to-date
- Secure
- Performing optimally
Patch management is a critical step in this process, as it helps organizations address the security vulnerabilities that threaten their systems and data.
By staying current with patches, organizations can minimize their risk and protect themselves against known threats.
However, many other factors contribute to an organization’s overall security posture, including network security, access controls, user training, and incident response.
By incorporating patch management into a broader vulnerability management program, organizations can effectively manage their security risk and maintain the confidence of their customers, partners, and stakeholders.

Step 1: Identify and Assess Vulnerabilities
The first step in the patch management process is to identify and assess the vulnerabilities in your systems and applications.
This involves using vulnerability scanning tools to identify potential weaknesses in your IT infrastructure.
The goal is to identify all vulnerabilities that could impact your security posture and prioritize them based on their severity.
This helps to ensure that the most critical vulnerabilities are addressed first.
It’s important to note that vulnerabilities with a lower risk score shouldn’t be ignored.
Often times these lower-scored vulnerabilities can be the entry of a greater attack path that threat actors use to compromise an organization’s network.
Step 2: Evaluate Available Patches
Once you have identified the vulnerabilities, the next step is to evaluate the available patches.
This involves reviewing the patches that are available to address the vulnerabilities and determining which ones are appropriate for your organization.
Factors such as the age of the patch, the number of vulnerabilities it addresses, and the impact on your IT infrastructure will be considered.

Step 3: Test and Deploy Patches
After evaluating the available patches, the next step is to test and deploy them.
This involves testing the patches in a controlled environment to ensure that they do not cause any unintended consequences or disruptions.
Once the patches have been tested and validated, they can then be deployed to the production environment.
Step 4: Monitor And Verify
The final step in the patch management process is to monitor and verify that the patches have been successfully deployed and are functioning as intended.
This involves monitoring your systems for any issues or unintended consequences and verifying that the vulnerabilities have been addressed.
Ongoing monitoring is critical to ensure that new vulnerabilities are identified and addressed in a timely manner.
