Our Cyber Security Services
Managed Cyber Security Services
Cyber security isn’t a one-time setup; it requires continuous management.
Our Managed Cyber Security Service provides ongoing protection across your environment, ensuring your systems, users, and data are secured against evolving threats. The service includes:
- Endpoint and user protection
- Security configuration and management
- Ongoing monitoring and improvement
- Alignment with recognised security standards.
With a proactive protection approach, we help UK businesses strengthen defence systems, maintain business continuity, and preserve their reputations.
Managed SOC — 24/7 Cyber Security Monitoring
Most cyber attacks occur outside working hours.
With the help of our Security Operations Centre (SOC) services, we provide 24/7 monitoring, detection, and response, identifying and stopping threats before they cause damage:
- Real-time threat monitoring
- Incident detection and response
- Continuous log analysis (SIEM)
- Expert-led investigation and escalation protocols.
This enterprise-grade security helps detect malicious and suspicious activity, even when you’re away. It’s accessible to mid-sized organisations.
Cyber Security Essentials and Compliance Support
Achieving compliance and protecting your business shouldn’t be complex.
At Nexus, we’ll help you prepare for and achieve Cyber Essentials and Cyber Essentials Plus, ensuring your business meets recognised security standards. We help with the following:
- Gap analysis and readiness assessments
- Remediation and security improvements
- Certification support
- Ongoing compliance guidance.
Our team helps UK businesses navigate breach risks, avoid GDPR fines, secure supply chains, and gain a competitive advantage.

We help you identify and fix security weaknesses before attackers do.
Our automation penetration testing services simulate real-world attacks to identify vulnerabilities before attackers do. We do this by:
- Automated, hybrid, and manual testing
- Web application testing
- Actionable reporting and remediation guidance
- Improved security posture and assurance.
Our penetration testing system helps you demonstrate compliance with industry regulations, identify security vulnerabilities, and improve confidence in your systems.

- Ongoing visibility of your security posture.
Vulnerability scanning helps your business identify and prioritise emerging system weaknesses, apply timely patches, and reduce exposure to cyber threats.
Business Continuity and Disaster Recovery (BCDR)
Even with strong cyber security, data can still be lost.
Our BCDR solutions ensure your business can recover quickly and continue operating with minimal disruption. Each system aims at protecting UK businesses against physical, virtual and cloud attack by:
- Disaster recovery planning
- Rapid system and data restoration
- Business continuity strategies
- Reduced downtime and operational impact.
Our BCDR system provides comprehensive protection to UK businesses against all threats, from malware and human error to physical disasters and malicious activity.
