A vulnerability assessment is a systematic scan of your network and infrastructure that identifies and prioritises security weaknesses before attackers can exploit them.
Automated Scanning
Our vulnerability scanner continuously monitors your internal and external infrastructure - identifying weaknesses in systems, network devices, and communication equipment before attackers can exploit them.
Broader Risk Coverage
Unlike penetration testing, a vulnerability assessment uses advanced scanning tools to deliver a high-level view of risks across your entire environment, giving you complete visibility of your attack surface.
Prioritised Findings Report
Every assessment produces a clear, actionable report with findings mapped to risk severity - so your team knows exactly what to fix first and can drive a structured remediation programme without delay.
Fast and Cost-Effective
Scalable and efficient, a vulnerability assessment is the ideal starting point for organisations looking to understand their security posture, meet compliance requirements, and strengthen defences quickly.

Is a Vulnerability Assessment Right for My Organisation?
A vulnerability assessment is the recommended starting point for any UK organisation that wants to understand its security exposure – particularly if you have never undertaken formal security testing, are approaching a compliance deadline, or need a cost-effective way to gain visibility across a large or complex environment.
CyberLab’s vulnerability assessments are suited to organisations of all sizes across the public and private sector. If you handle sensitive customer data, operate critical infrastructure, or are subject to regulatory requirements such as PCI DSS, ISO 27001, or Cyber Essentials Plus, regular vulnerability scanning should form a core part of your security programme. Our fully automated scanning service monitors your internal and external infrastructure continuously, identifying new weaknesses as they emerge rather than providing a point-in-time snapshot.
For organisations requiring independent, accredited assurance, we also deliver CREST-approved vulnerability assessments conducted by our team of certified penetration testers – providing a higher level of rigour and a report suitable for board-level reporting or third-party audit purposes.
Fully-Automated Vulnerability Assessments
CyberLab’s automated vulnerability scanning service, powered by HackRisk, continuously monitors your external attack surface – scanning for new vulnerabilities every 24 to 48 hours across your network, internet-facing systems, and digital infrastructure.
Unlike a one-off assessment, automated scanning gives you ongoing visibility as your environment changes and new CVEs emerge. Sign up to HackRisk today and get a free HackRisk Report with 14 days of portal access.
Penetration Tests vs Vulnerability Assessments
Vulnerability Assessments are used to identify system and software vulnerabilities and provide a high-level overview of overall security posture. They are an effective way for companies who do not have visibility of their security posture to gain a more complete understanding. For organisations with legacy infrastructure, it is a quick and cost-effective way to identify and focus on software and systems that can be fixed easily.
A Penetration Test not only identifies security issues within infrastructure, systems, and operations, but exploits these vulnerabilities and, if necessarily, combines them to achieve a specific objective. For example, if the objective is to gain internal network access, we would find a vulnerability that allows file uploads, then another one that lets us find those files, and another one that marries these up to execute something malicious.
It’s not the testing process that matters the most – it’s implementing the remediation actions from the reports to proactively improve your security posture.
Our team of accredited experts can help you demystify a Pen Test report and incorporate the fixes.
Success Stories
Nottingham City Council
Following a rigorous, detailed process, Nottingham City Council selected CyberLab as their penetration testing partner on a range of criteria including competitive pricing, technical expertise, experience, and supplier fit.
“We needed to find a way to meet very tight budget constraints. Of the suppliers we spoke to, only CyberLab demonstrated what we felt was a genuine desire to engage with us to reach a workable solution for both parties. I’d recommend CyberLab not just for their expertise in the whole cybersecurity area, but for their personalised and professional approach.”

Frequently Asked Questions
A vulnerability assessment is a systematic process of identifying, classifying, and prioritising security weaknesses across an organisation’s IT infrastructure, including networks, systems, applications, and devices. Unlike penetration testing, which actively exploits vulnerabilities, a vulnerability assessment uses automated scanning tools to provide a broad, prioritised view of your attack surface – giving you the visibility needed to drive a structured remediation programme.
For most organisations, a vulnerability assessment should be performed at least quarterly. However, assessments should also be carried out following any significant changes to your IT environment – such as new system deployments, network changes, or cloud migrations – as these can introduce new weaknesses. Organisations subject to PCI DSS are required to run external vulnerability scans monthly via an Approved Scanning Vendor (ASV). CyberLab’s automated scanning service via HackRisk provides continuous coverage between formal assessments.
A CyberLab vulnerability assessment covers internal and external infrastructure, including servers, network devices, firewalls, endpoints, and communication equipment. Our CREST-approved assessments also include web-facing systems and cloud environments where in scope. Every assessment produces a prioritised findings report mapped to risk severity, with clear remediation guidance so your team knows exactly what to fix and in what order.
A vulnerability assessment identifies and ranks known weaknesses using automated scanning tools – it tells you what is exposed across your environment. A penetration test goes further by having certified ethical hackers actively attempt to exploit those weaknesses, chaining vulnerabilities together to demonstrate real-world attack impact. A vulnerability assessment is broader and faster; a penetration test is deeper and more targeted. Many organisations use vulnerability assessments for ongoing monitoring and penetration testing for periodic, in-depth assurance.
Yes. PCI DSS v4.0 Requirement 11 mandates both internal and external vulnerability scanning at least quarterly, and after any significant change to the network. External scans must be conducted by a PCI SSC-approved Approved Scanning Vendor (ASV). Internal scans must be performed by a qualified internal resource or third party. CyberLab can support both requirements – speak with our team to understand how vulnerability scanning fits into your broader PCI DSS compliance programme.
