If your business relies increasingly on digital systems, there could be more suspicious activity to track.  Without continuous oversight of your IT environment, cyber security threats can go unnoticed.

Utilising cyber security monitoring can help you identify and investigate potential threats early.  However, what does that mean, and does your business need it?

This guide explains:

• How 24/7 managed IT security services work
• Why cyber security monitoring matters for regulated businesses
• How proactive cyber security can help reduce the risk of security incidents
• Why managed cybersecurity services can strengthen digital resilience for businesses

What is cyber threat monitoring?

Cyber threat monitoring is a managed IT security service.  It provides continuous oversight of an organisation’s networks, devices, users and systems.  This helps spot potential cyber threats.

An external cyber security provider usually carries out cyber threat monitoring for regulated businesses.  IT security specialists investigate suspicious activity, identify potential threats and recommend what to do next.

What tools are used for cyber threat monitoring?

The most common tools for cyber threat monitoring are SIEM, EDR and XDR.

These tools help cyber threat intelligence specialists identify unusual behaviour.  They flag potential threats and provide the information they need to investigate further.

Let’s take a closer look:

• Security information and event management (SIEM) – collects and analyses security data from across an organisation’s IT environment, helping identify and flag suspicious activity.
• Endpoint detection and response (EDR) – monitors individual devices, such as laptops and servers, for malware, suspicious behaviour and other security threats.
• Extended detection and response (XDR) – brings together threat data from multiple sources, such as endpoints, cloud services and servers, to provide a broader view of potential attacks.

Good to know: Managed cybersecurity services, such as those provided by the IT experts at David Allen, combine specialist technology with expert human oversight.  

How cybersecurity threat detection works

Managed cybersecurity threat detection works by combining continuous monitoring with automated technology and human expertise to help businesses identify and respond to potential cyber threats.

Here are the steps involved in our managed cybersecurity services:

1. Monitor.  We monitor your systems using security tools to continuously scan your network, devices, applications, cloud services and user activity.  This is done by collecting data from security logs and alerts to assess risks within the context of your organisation.
2. Detect.  We use automated tools to search for known threats, unusual patterns and suspicious activity that could indicate a cybersecurity issue.
3. Triage.  Alerts flagged by our automated tools are reviewed by our SOC (Security Operations Centre) and cybersecurity specialists.  They determine whether these alerts represent a genuine threat and prioritise issues based on severity.
4. Respond.  When genuine threats are confirmed, we take appropriate action and escalate as required to contain and neutralise the issue.
5. Review.  Following an incident, we analyse findings, identify any breaches and strengthen security controls to improve monitoring and reduce the risk of similar issues recurring.

Worth knowing: Cyber security services like this are sometimes confused with data or digital compliance checks.  In reality, they serve quite different purposes.  Keep reading.  

The difference between managed security and compliance audits

Compliance audits assess whether an organisation meets requirements at a point in time, while managed security provides continuous, active protection against cyber threats.  This table breaks down the key differences:

Why regulated businesses need proactive threat monitoring

In the UK, regulated businesses need proactive threat monitoring because they often have additional responsibilities around protecting sensitive information, maintaining essential services and managing cybersecurity risk.

Proactive cybersecurity threat detection can support these responsibilities by helping organisations identify potential security issues in real-time.

The Information Commissioner’s Office (ICO) is responsible for monitoring GDPR compliance in the UK.  For organisations handling personal data, security monitoring can identify unusual activity and respond appropriately to potential threats.

Incident response: What happens when a cyber threat is detected?

A business with security monitoring in place can identify and investigate threats immediately.  One without it must work backwards after the fact, often at a slower pace and higher cost.

This table compares what happens at each stage of incident response, depending on whether a business has managed security monitoring in place.

The cost of undetected cyber security threats

Cyber attacks come at a cost: financial loss, prolonged service disruption, and exposure of customers’ personal data.  Early detection is key to limiting the scope and impact of potential security breaches.

The 2025 National Cyber Security Centre’s (NCSC) annual review reveals that its Incident Management Team handled 429 cyber incidents during 2024-25, including 204 highly significant or significant incidents.

Research by the Department for Science, Innovation and Technology (DSIT) estimates that the average cost of a significant cyber attack to an individual business is approximately £195,000.

In addition, the potential negative effects of an undetected threat can include:

• Operational downtime.  This affects systems, productivity and revenue.
• Recovery and cleanup.  Costs associated with outside experts to investigate breaches, clean and restore data.
• Reputational damage.  Customers can lose trust, leading to revenue loss and negative brand recognition.

How managed IT security services support business resilience and growth

Managed IT security services help businesses protect against threats while supporting long-term growth, giving organisations the confidence to focus on what matters most.

In our increasingly digital world, businesses that adopt new technologies to protect and improve their organisation are more resistant to potential security threats.

The benefits of managed IT security services include:

• Better data protection
• 24/7 monitoring and threat detection
• Access to specialist expertise
• Support with regulatory compliance
• Cost savings compared to building an in-house solution
