Cybercriminals continuously search for vulnerabilities. Whether seeking outdated software, misconfigured devices, or unprotected systems, these criminals will search for a way to exploit these vulnerabilities for financial gain, data theft, or disruption. Without proactive measures, these weaknesses can leave your business exposed to devastating security breaches.
One of the most effective ways to mitigate these risks is through regular network vulnerability scanning. Understanding how to scan networks for vulnerabilities enables businesses to identify weaknesses, prioritise risks, and strengthen their defences. This guide provides a step-by-step guide for conducting effective vulnerability scans to ensure your organisation stays secure.
Step 1: Define Your Scanning Scope and Objectives
The first step in conducting a successful vulnerability scan is defining your scope and objectives. Scanning an entire network without proper planning can lead to missed vulnerabilities, operational disruptions, or wasted resources. A well-defined scope ensures that your efforts are focused and effective.
Identify Assets to Be Scanned
Begin by identifying which assets within your network need to be scanned. These could include:
- Servers and workstations.
- Network devices such as routers, switches, and firewalls.
- Applications, including web services and databases.
- IoT devices or connected endpoints.
Prioritise critical assets that store sensitive data or support essential operations, as these are high-value targets for attackers.
Set Security Goals
Clearly define your objectives for the scan. For example, you may want to:
- Identify unpatched systems and software vulnerabilities.
- Ensure systems adhere to secure configuration standards such as
- CIS Benchmarks or Microsoft Baselines
- Ensure compliance with industry regulations such as GDPR or PCI DSS.
By establishing goals, you can tailor the scanning process to address your organisation’s unique risks and requirements. Learn more about vulnerability scanning and detection on our FoxTech Assure page.
Step 2: Select the Right Vulnerability Scanning Tools
Choosing the right tools is crucial for effective vulnerability scanning. The tools you select should align with your organisation’s size, network complexity, and security needs. While some organisations may use off-the-shelf software, others prefer partnering with experts to ensure accurate and thorough assessments.
Consider Your Business Needs
- Small Businesses: Lightweight tools or cloud-based solutions can provide cost-effective and efficient scanning.
- Medium to Large Enterprises: Larger networks require robust solutions capable of handling complex environments and integrating with existing security systems.

Step 3: Perform the Scan and Monitor the Process
Once your scope and tools are defined, it’s time to conduct the scan. This stage requires careful execution to ensure the process runs smoothly without impacting network performance or business operations.
1. Schedule the Scan
Choose a time that minimises disruptions, such as during off-peak hours. Scans can consume significant bandwidth, so planning the timing ensures uninterrupted services for end users.
2. Launch the Scan
Initiate the vulnerability scan using the selected tools or services. During the scan, your system will be assessed for:
- Open ports and services.
- Outdated software or unpatched systems.
- Misconfigurations in devices and applications.
3. Monitor the Scan
It’s essential to monitor the scanning process to ensure it completes without issues. Look for:
- Errors or interruptions during the scan.
- Signs of excessive system strain that may require adjustments to the scanning configuration.
By carefully managing this phase, you can maximise the effectiveness of the scan while minimising its impact on your operations.
Step 4: Analyze the Scan Results and Prioritise Risks
After completing the scan, you’ll receive a report detailing vulnerabilities discovered across your network. Analysing these findings is critical to identifying high-risk areas that need immediate attention.
Review the Findings
Your scan report will typically categorise vulnerabilities by severity:
- Critical: High-impact vulnerabilities that could lead to immediate compromise if exploited. These require urgent remediation.
- High: Significant risks that should be addressed promptly.
- Medium/Low: Lower-priority issues that can be scheduled for later remediation.
Identify Root Causes
Determine why vulnerabilities exist and whether they are due to unpatched software, outdated configurations, or other factors. This information helps prevent similar issues from recurring.
Leverage Expert Insights
If you’re working with a professional vulnerability scanning service like FoxTech Assure, our team will provide detailed guidance on prioritising risks and implementing fixes. Expert-led analysis ensures that your organisation can take effective action without wasting resources.
Step 5: Implement Fixes and Re-Scan to Verify Security
Identifying vulnerabilities is only the first step—remediation is where the real value of vulnerability scanning lies. Addressing identified risks promptly and re-validating your network’s security are essential for ensuring lasting protection.
1. Implement Remediation
Work with your IT or security team to resolve high-priority vulnerabilities. Common remediation actions include:
- Applying patches or updates to software and systems.
- Reconfiguring firewalls, routers, or other network devices.
- Strengthening access controls and user permissions.
Document all remediation efforts to track progress and support compliance reporting.
2. Conduct a Follow-Up Scan
Once fixes have been implemented, run a follow-up scan to confirm that vulnerabilities have been addressed successfully. This process also helps ensure no new risks were introduced during remediation.
3. Build a Continuous Improvement Process
Vulnerability management is an ongoing process, not a one-time activity. Regular scans, combined with lessons learned from previous assessments, ensure that your network remains secure against emerging threats.

Enhancing Security Through Regular Network Scans
Regularly scanning your network for vulnerabilities is one of the most effective ways to protect against cyber threats. Here’s how consistent scanning enhances your organisation’s overall security:
1. Proactive Risk Mitigation
Frequent scans ensure that vulnerabilities are identified and addressed before they can be exploited by attackers.
2. Improved Compliance
Many regulatory standards, such as GDPR and PCI DSS, require regular vulnerability assessments. Consistent scanning helps organisations meet these requirements and avoid penalties.
3. Reduced Downtime
By proactively identifying weaknesses, organisations can prevent incidents that lead to costly downtime or disruptions.
4. Strengthened Reputation
Demonstrating a commitment to cybersecurity builds trust with customers, partners, and stakeholders, enhancing your organisation’s reputation.
