The internet-facing systems that represent your business are often the first place attackers look for weaknesses
For many UK organisations, the NCSC Web Check service quietly provided an important layer of security visibility. Developed by the UK’s National Cyber Security Centre, Web Check allowed businesses and public sector organisations to quickly assess whether their websites had common security issues or misconfigurations that could expose them to cyberattacks.
But with the retirement of the NCSC Web Check tool, organisations have lost a simple, accessible way to evaluate the security posture of their public-facing websites. For CEOs and business leaders responsible for protecting their organisation’s digital presence, this change highlights an important reality: monitoring your external attack surface is becoming both more critical and more complex.
The internet-facing systems that represent your business are often the first place attackers look for weaknesses — and without the right monitoring tools, vulnerabilities can go unnoticed until it’s too late.
What the NCSC Web Check Tool Did
NCSC Web Check was designed to help organisations quickly understand how their websites appeared to attackers scanning the internet. The tool analysed public-facing websites and provided insights into common security weaknesses. For smaller organisations without dedicated security teams, the tool offered an easy way to spot potential risks without needing specialist expertise.
While Web Check was never intended to replace professional security assessments, it provided a useful first layer of visibility into publicly accessible vulnerabilities. With its retirement, that visibility gap becomes more noticeable.
Why Website Security Monitoring Matters
Your website is more than just a marketing platform. It is often the primary digital identity of your organisation. Customers interact with it. Partners trust it. Employees rely on it. And attackers study it. Public-facing websites can reveal far more than most organisations realise. Attackers routinely scan the internet looking vulnerabilities. Even small misconfigurations can provide an entry point for attackers.
Once inside, cybercriminals may attempt to steal data, manipulate your website, install malware or direct your customers to a completely separate site. The outcomes are all bad for your business. These risks can quickly escalate into reputational damage, regulatory scrutiny, and financial loss.
The Growing Importance of External Security Visibility
One of the challenges organisations face is that many of these risks exist outside traditional security monitoring tools. Most security systems focus on internal networks, endpoints, and user activity. But attackers rarely start inside the organisation. They begin by analysing the organisation from the outside. Without visibility into these external signals, organisations may not realise how exposed their digital footprint really is.
The Gap Left by the NCSC Web Check
With the retirement of NCSC Web Check, organisations lose a simple way to perform basic external assessments of their websites. For many businesses particularly SMEs this raises important questions. How often should our website be checked for vulnerabilities? Are our web technologies up to date and secure? Could attackers identify weaknesses in our infrastructure? Are we monitoring for new exposures as our digital footprint evolves?
Without automated monitoring, these checks often become manual, infrequent, or overlooked entirely. Yet the threat landscape continues to evolve rapidly.
Why Attackers Focus on Public Web Infrastructure
Cyber criminals prefer attacking the easiest entry point. Public web infrastructure often provides that opportunity. Unlike internal systems, public websites are easily discover able and continuously accessible. Attackers use automated scanning tools to analyse millions of websites for vulnerabilities. If a weakness is detected, it may be exploited within hours.
Why CEOs Should Pay Attention
Cybersecurity is often viewed as a technical issue handled by IT teams. But when website vulnerabilities lead to breaches, the consequences quickly become business issues. A compromised website can result in customer data exposure and business disruption. For organisations operating in regulated sectors, failing to identify known vulnerabilities can also raise compliance concerns.
For CEOs, the key challenge is ensuring their organisation has continuous visibility into external risks rather than relying on periodic audits.
Moving Beyond Basic Website Checks
While tools like NCSC Web Check provided useful insights, modern cyber threats require a broader approach. Today’s organisations need to monitor not only their websites but their entire external digital footprint. This includes their executive personal digital exposure, social media signals and dark web leaks. Together, these factors shape how attackers perceive and target your organisation.
How CyberSentrx Helps Fill the Gap
With services like NCSC Web Check no longer available, businesses need new ways to monitor their external risk landscape. CyberSentrx provides an external identity threat detection platform designed to give organisations continuous visibility into how their digital presence appears to attackers.
The platform monitors several key areas:
Public Web Vulnerabilities
CyberSentrx continuously scans internet-facing assets to identify vulnerabilities and mis-configurations that attackers could exploit.
Executive Digital Exposure
Executives and leadership teams are frequent targets of social engineering attacks. The platform identifies publicly available information that could be used to impersonate or manipulate them.
Dark Web Intelligence
CyberSentrx monitors underground forums and breach databases for stolen credentials, leaked data, or brand mentions linked to your organisation.
AI-Driven Remediation Guidance
Rather than simply highlighting problems, the platform provides actionable recommendations to help organisations fix vulnerabilities quickly.
This combination of visibility and guidance helps businesses reduce risk across their external digital footprint.

From Reactive Security to Proactive Visibility
The retirement of tools like NCSC Web Check reflects a broader shift in cyber security responsibility. Organisations can no longer rely on free or ad-hoc tools alone to monitor their digital exposure. Instead, businesses need a proactive approach that continuously monitors the signals attackers use to identify targets. External identity protection platforms provide this visibility by transforming scattered data into meaningful security intelligence.
For organisations that want to stay ahead of evolving threats, this kind of insight is becoming essential.
Final Thought
Your website is often the first thing customers see when they interact with your business. It is also often the first thing attackers analyse when planning an attack. With the retirement of NCSC Web Check, organisations have lost a simple way to assess their web security posture. But the need for monitoring has not disappeared if anything, it has become more important than ever.
Understanding how exposed your organisation is on the public internet is the first step toward reducing cyber risk.
