Testing your business systems, networks and applications.
Your IT systems hold data, support daily operations and connect your people, customers and suppliers. Penetration testing helps identify weaknesses before they can be exploited.
Your Digital Services can support carefully scoped testing across external networks, internal environments, web applications, APIs, cloud services and wireless networks.
Common IT testing areas
OT security testing with a risk-aware approach.
Operational Technology environments can support physical processes, smart buildings, monitoring systems and critical operations. Testing these environments requires careful scoping, controlled activity and a focus on avoiding disruption.
Controlled OT security assessment
OT environments are not tested in the same way as standard office IT systems. Where live systems are involved, YDS can support a cautious approach that considers system sensitivity, operational safety, uptime and business continuity.
- ✓OT network and segmentation review to understand how operational systems are separated and protected.
- ✓Firewall, remote access and supplier access review to identify unnecessary exposure.
- ✓Passive or controlled assessment options where aggressive testing would not be appropriate.
- ✓Clear recommendations that support risk reduction without unnecessary operational disruption.
Vulnerability scanning that supports deeper security testing.
Vulnerability scanning can help identify known weaknesses, missing patches, exposed services and configuration issues before or during a penetration testing engagement.
Where appropriate, YDS can use licensed scanning tools such as Nessus, combined with professional review and validation, so your organisation receives useful findings rather than only raw automated output.
Scan, validate, prioritise
Automated scanning is useful, but the value comes from understanding which issues matter, how they affect the business and what should be fixed first.
If you only need a website vulnerability scan, YDS also offers a dedicated Web Vulnerability Scanning service.
View Vulnerability ScanningHow we scope your penetration test.
Penetration testing is not a one-size-fits-all service. Each engagement is scoped around your systems, objectives, risk level, access requirements and business priorities.
Discovery call
We discuss what you need tested, your business objectives, deadlines and any compliance or assurance requirements.
Scope definition
We confirm systems, applications, networks, sites, users, access routes and any areas that should be excluded.
Rules of engagement
Testing boundaries, safe testing windows, escalation contacts and sensitive systems are agreed before work starts.
Testing activity
YDS carries out the agreed testing activity using controlled methods appropriate to the environment and scope.
Report and guidance
You receive clear findings, business risk context and practical remediation guidance for your team or suppliers.
Retest or closure review
Where required, YDS can support retesting or a closure review once remediation work has been completed.
Why Penetration Testing Matters
Cyber criminals and opportunistic attackers are constantly looking for weaknesses. Penetration testing helps your organisation understand where it may be exposed before those weaknesses become costly incidents.
Penetration testing helps you:
- Identify weaknesses before attackers do
- Understand real-world business risk
- Support tenders, compliance and supplier assurance
- Protect systems, data and reputation
- Prioritise remediation based on impact
- Give senior stakeholders clear visibility
- Support technical teams with practical next steps
Clear findings, practical guidance and next steps.
A penetration test is only valuable if the results are easy to understand and realistic to act on. YDS reporting is designed to support both senior decision-makers and the teams responsible for fixing issues.
For leadership teams
Senior stakeholders need to understand what the findings mean for the organisation, not just the technical detail behind them.
- ✓Plain-English executive summary.
- ✓Clear explanation of business risk and likely impact.
- ✓Prioritised actions to help focus time and budget.
- ✓Board-level presentation or remediation workshop where required.
For technical teams
IT teams, developers and suppliers need enough detail to understand, reproduce and remediate the issues identified.
- ✓Technical findings with supporting evidence where appropriate.
- ✓Risk ratings and remediation priority.
- ✓Practical guidance for fixes, configuration changes and hardening.
- ✓Retesting or closure review options after remediation.
