Network Vulnerability Assessment
Business networks connect employees, applications, servers, devices, offices, cloud services, and external partners. This connectivity supports daily operations, but it also creates routes that attackers can use if systems are outdated, incorrectly configured, or unnecessarily accessible.
Network weaknesses are not always obvious. A vulnerable service may continue to operate normally, an old device may remain connected after its original purpose has changed, and access rules introduced for a temporary project may never be removed.
A Network Vulnerability Assessment from CA helps you identify and understand weaknesses across your internal and external network environment. We combine technical scanning with practical analysis to show which issues create a genuine risk and what should be done to address them.
Why This Matters
Networks develop over time. New systems are connected, offices are opened, remote access is introduced, cloud services are adopted, and equipment is replaced. Documentation and security controls do not always keep pace with these changes.
As a result, organisations may have systems they no longer recognise, services that should not be accessible, or vulnerabilities that have remained unresolved for months. An attacker only needs one suitable entry point to gain initial access and begin moving through the environment.
A network vulnerability assessment helps you:
Find vulnerable systems and services
Identify known vulnerabilities, unsupported software, outdated protocols, and configurations that can expose the network to attack.
Understand network exposure
Determine which systems can communicate with one another and where unnecessary access could allow a threat to spread.
Prioritise remediation work
Focus attention on vulnerabilities that are realistically exploitable and affect important systems or business processes.
Improve the quality of asset information
Discover devices and services that may be missing from existing inventories or are no longer under active management.
Our Approach
We do not treat a vulnerability scan as a complete assessment. Automated tools can identify many potential issues, but they do not always explain whether a finding is relevant, how it could be exploited, or what it means for the organisation.
Our approach combines automated discovery and scanning with manual validation, network context, and business risk. We examine how systems are connected, which services they support, and what could happen if a vulnerability were successfully exploited.
Define the scope and understand the network
We begin by agreeing which locations, networks, systems, and device groups should be included in the assessment.
The scope may cover internal networks, externally accessible infrastructure, servers, workstations, network devices, wireless environments, virtual systems, remote-access services, and selected operational technology.
We review available network diagrams, asset inventories, technical documentation, previous assessment results, and known business constraints. We also identify critical systems that require special handling to avoid unnecessary disruption.
This preparation helps ensure that the assessment covers the relevant environment and that testing is performed safely.
Discover assets and assess vulnerabilities
We identify active devices, accessible services, operating systems, applications, open ports, and other technical characteristics within the agreed scope.
The identified systems are assessed for known vulnerabilities, missing security updates, unsupported software, weak protocols, configuration problems, exposed management services, and other conditions that may increase the likelihood of compromise.
Where appropriate, authenticated assessment methods are used to provide a more accurate view of installed software, missing updates, and local security configurations.
We also compare discovered assets with existing records. This can reveal unknown systems, incomplete inventories, and devices that are no longer actively managed.
Validate findings and evaluate business risk
Automated results are reviewed to confirm that the identified vulnerabilities are present and relevant to the environment.
We consider the accessibility of the affected system, the availability of known exploitation methods, existing security controls, network segmentation, and the importance of the supported business service.
For example, the same technical vulnerability may create very different levels of risk on an isolated test device and on a server containing sensitive customer information.
This analysis separates urgent issues from lower-risk findings and helps prevent technical teams from spending time on vulnerabilities that have limited practical significance.
Prioritise actions and support remediation
We provide a clear report describing the confirmed weaknesses, affected systems, potential consequences, and recommended actions.
Findings are prioritised according to technical severity, exploitability, exposure, asset importance, and possible business impact. Recommendations may include applying updates, replacing unsupported systems, disabling unnecessary services, strengthening configurations, restricting network access, or improving segmentation.
Where immediate remediation is not possible, we help identify temporary safeguards that can reduce risk until a permanent solution is available.
CA can also perform follow-up testing to confirm that corrective actions have been applied successfully.
What Sets CA Apart
More than an automated scan
We validate findings and explain their practical significance rather than providing an unfiltered list produced by a scanning tool.
Risk considered in context
We assess vulnerabilities in relation to network exposure, security controls, system importance, and potential business consequences.
Clear remediation priorities
We distinguish urgent vulnerabilities from issues that can be addressed through a planned improvement programme.
Practical and independent advice
Our recommendations are based on the needs of your environment and are not tied to the sale of a particular product.
The Business Value
A Network Vulnerability Assessment from CA gives your organisation a clearer understanding of the weaknesses present across its network environment.
Confirmed findings and practical priorities help technical teams focus their time and budget on issues that create the greatest risk. Unsupported systems, unnecessary services, weak configurations, and missing updates can be addressed before attackers use them to gain access or move through the network.
The assessment can also reveal wider management issues, such as incomplete inventories, inconsistent patching, weak network segmentation, and unclear ownership of equipment. Addressing these underlying problems helps prevent the same weaknesses from returning.
The result is a better-protected network, stronger control over connected systems, and a more reliable basis for security planning, audits, customer assessments, and future investment decisions.
Next Step
A vulnerability can remain unnoticed for a long time while the affected system continues to operate normally.
