Turn Risk into Perimeter
Vulnerability testing simulates real-world cyberattacks on your systems so you can discover and fix weaknesses before someone else does. HTL’s ethical hackers and security specialists help you understand your true risk and prioritise what to fix first.
Vulnerability testing is a vital component of a robust cybersecurity strategy. It helps your organisation:

A Controlled Vulnerability Test. Real-world Results.
Vulnerability testing simulates real-world cyberattacks on your IT systems to uncover vulnerabilities before hackers can exploit them.
Our ethical hackers use the same tools and tactics as cybercriminals to test your defences. The result? Actionable insights you can use to close security gaps and strengthen protection across your systems, applications, and networks.
Beyond simply identifying weaknesses, vulnerability testing provides a clear roadmap for improvement. It helps your IT and leadership teams prioritise remediation efforts based on real-world risk, ensuring that security investments deliver measurable impact. By turning technical findings into practical steps, you gain the confidence that your organisation is prepared for today’s evolving threat landscape.
Vulnerability testing is normally carried out alongside our Cyber Security Services, Internet Security and IT Service Continuity to make sure findings translate into practical improvements and better resilience.

- Need to show due diligence to regulators, auditors or enterprise customers.
- Plan to pursue Cyber Essentials or ISO 27001 certification.
- Have recently migrated to cloud services or expanded remote working.
- Have never had a formal test and want a realistic view of your current exposure.

Frequently Asked Questions
Will vulnerability testing disrupt our business?
Testing is carefully planned to avoid disruption to normal operations. Most checks are carried out remotely and outside peak hours, with clear communication if anything needs to be done differently.
Is vulnerability testing the same as penetration testing?
They’re related but not identical. Vulnerability testing focuses on finding and rating weaknesses; penetration testing goes further, exploring how far an attacker might get. We can advise on which approach is best for you.
How often should we run a vulnerability test?
Many organisations test annually, and after major changes such as new systems, mergers or big cloud migrations. The right frequency depends on your risk profile and regulatory requirements.
