Cyber Security
24/7 cyber security monitoring & response
Most security tools generate alerts. We investigate and respond to them.
Spot suspicious activity, understand what matters and coordinate a response. Our managed cyber defence brings together endpoint, email, identity and Microsoft 365 threat monitoring, with 24/7 security operations and clear monthly reporting, without the need to build your own security operations team.
Prevention is not enough. Who responds to the alerts?
Security tools are one part of the picture. Your business also needs suspicious activity to be monitored, alerts to be investigated and response activity to be coordinated when an incident is identified. Your Secure Defend brings those capabilities together without asking you to build an internal security operations centre.
Most security tools generate alerts. We investigate and respond.
Layered protection across endpoint, email, network, identity and Microsoft 365, delivered through one managed platform rather than a patchwork of separate tools.
Is this you?
You need security operations, not another tool
You want continuous cyber defence capability, but do not have an internal security operations centre or want to build one. You need monitoring, investigation and escalation managed for you.
A cyber incident would disrupt your business
Ransomware, email fraud, account compromise or endpoint threats represent a material risk to your operations. You need layered protection and a coordinated response when suspicious activity is identified.
You need clearer incident readiness
Your leadership team wants better cyber insurance readiness and confidence in how incidents will be handled. You need clearer risk visibility, reporting and response coordination.
Your internal IT team needs specialist support
Your IT team needs additional threat monitoring, investigation and response capability. You want specialist cyber defence alongside the team you already have, without replacing its role.
What better Microsoft 365 security means for your business
Clearer control over access, fewer unnoticed changes and better evidence for leadership. These are the business outcomes our Microsoft 365 security service is designed to support.
A stronger security foundation
Your Microsoft 365 environment is reviewed and managed against a structured security baseline, giving you a clear starting point for ongoing improvement.
Lower identity and access risk
Multi-factor authentication, Conditional Access and administrator permissions are actively managed, helping reduce the risks around who can access your systems.
Clearer improvement priorities
Microsoft Secure Score is monitored and reviewed so you can see progress and focus effort on the security actions that matter most.
Fewer unnoticed security changes
Security settings are reviewed and monitored to identify configuration drift, so changes do not silently weaken the controls your business relies on.
Better evidence for cyber insurance
You can demonstrate that Microsoft 365 security is being actively governed and reviewed, supporting conversations with your insurer.
Safer Copilot and AI adoption
Data exposure, permissions and sharing risks are considered before wider AI adoption, helping you understand what needs attention before rollout.
Reporting your leadership can use
Plain-English summaries explain your security position, improvement actions and priorities, so decisions do not depend on interpreting technical reports.
What active cyber defence means for your business
Earlier visibility of threats, stronger protection and a coordinated response. These are the business outcomes our managed monitoring and response service is designed to support.
Earlier threat detection
Suspicious activity is monitored and investigated, helping you identify threats before they develop into a wider business incident.
Reduced ransomware risk
Layered endpoint, DNS and ransomware protection helps reduce exposure to encryption-based attacks and the disruption they can cause.
Stronger email defence
Protection against phishing, malicious links and attachments, impersonation and business email compromise helps reduce the risks reaching your people through email.
Clearer Microsoft 365 threat visibility
Microsoft 365 security alerts and identity-related signals are monitored and investigated, including suspicious sign-ins and potential account compromise.
Security operations without building a SOC
Gain monitoring, alert triage, escalation and response coordination without having to build and run an internal security operations centre.
Clearer confidence for leadership
Monthly reporting and incident coordination give your leadership team a clearer view of security events, actions taken and recommendations.
A simpler security stack
Multiple protection layers are managed through the Heimdal unified platform and delivered as one service, rather than a collection of disconnected tools.
Layered protection. Active investigation. Coordinated response.
Your Secure Defend brings protection, monitoring and investigation together through the Heimdal Unified Cybersecurity Platform. Instead of managing disconnected security tools, you get one service covering endpoint, email, network, identity and Microsoft 365 threats.
One managed platform, monitored 24/7
Security operations combine continuous monitoring, alert validation, threat investigation and escalation. When an incident is identified, response activity is coordinated so findings lead to action, not just another alert.
- 24/7 monitoring and alert validation
- Threat investigation and security escalation
- Incident coordination and containment guidance
- Monthly reporting and security recommendations
The layers working together
Endpoint protection and response
Protect the devices your people use with next-generation antivirus, endpoint detection and response, behavioural monitoring and malware remediation. Automated threat containment is used where supported by policy.
Predictive DNS security
Help stop devices communicating with malicious infrastructure. Threat intelligence-driven filtering blocks malicious domains and command-and-control activity, with network-level protection where deployed.
Ransomware encryption protection
Reduce exposure to encryption-based disruption with dedicated ransomware controls. Signature-free behaviour monitoring and automated containment of suspected ransomware activity provide another layer of protection.
Email security and fraud prevention
Strengthen protection against phishing, spam, malicious attachments and links. Email Fraud Prevention and business email compromise controls help reduce impersonation and social engineering risks.
Microsoft 365 threat monitoring
Watch for compromise, not just configuration. Microsoft 365 alerts, suspicious sign-ins, privileged accounts and identity-related activity are monitored and investigated, with escalation when required.
Threat hunting and unified monitoring
Bring security events together for investigation and prioritisation. Centralised alert triage, threat hunting workflows, event correlation and evidence gathering support coordinated response activity.
Clear response scope. The service includes escalation, containment guidance and incident response coordination. Major incident remediation or recovery projects are scoped separately where required. Microsoft 365 security governance sits with Your Secure 365; user and device support sits with Your Workplace.

Frequently Asked Questions
Your questions about 24/7 cyber security monitoring, incident response and working with our security team.
What does 24/7 cyber security monitoring and response include?
The service combines endpoint, DNS, ransomware and email protection with Microsoft 365 threat monitoring. Security operations monitor alerts, investigate suspicious activity and coordinate response when an incident is identified. Monthly reports explain security events, actions and recommendations.
We already have antivirus. Why do we need monitoring too?
Antivirus is one protection layer, but it does not replace the need to investigate suspicious activity across email, user accounts and Microsoft 365. Monitoring and response adds alert review, threat investigation and escalation, so your business is not left to interpret and act on security warnings alone.
Who do we speak to if something happens?
Fern Ritchie and Narayan Dosanjh provide the business-facing link to the 24/7 security operations centre team. They help explain findings and coordinate response activity with your internal IT team or provider. The round-the-clock coverage refers to the security operations service, rather than either individual’s personal availability.
What happens when a security incident is identified?
The service includes escalation, containment guidance and coordination of response activity. Automated containment is used where supported by policy. Major incident remediation or recovery projects may require a separate scope of work, rather than being included automatically in the monthly service.
Can you work alongside our existing IT team or provider?
Yes. The service can add specialist monitoring, investigation and response capability without replacing your existing IT support arrangements. Our security team helps coordinate findings and recommended actions with the people responsible for your systems.
Is this the same as Microsoft 365 security management?
No. This service monitors Microsoft 365 threats, including suspicious sign-ins and potential account compromise. Microsoft 365 Security, delivered through Your Secure 365, focuses on ongoing governance, configuration, access policies and improvement. The two services can work alongside each other.
Does this guarantee we will not suffer a cyber attack?
No service can guarantee that. Layered protection, continuous monitoring and investigation help reduce risk and support a coordinated response, but they do not remove every threat. The aim is stronger protection, earlier visibility and clearer action when suspicious activity is identified.
