January 23, 2025

In today’s cyber threat landscape, businesses of all sizes and industries are at risk. While tools like endpoint protection and firewalls are critical, they are not enough to prevent advanced cyber-attacks. Organisations need a Managed Detection and Response (MDR) solution to protect against the financial, reputational and operational damage a breach can cause. Here’s why: 

1. Cyber Threats Target All Businesses with Sensitive Data

Any organisation storing valuable information—whether it’s customer payment details, employee records or proprietary intellectual property—is a target for attackers. Small and medium-sized businesses are often at greater risk due to their perceived weaker defences.

In the UK alone, over 250 cyber breaches are reported daily. With ransomware, phishing and credential theft evolving rapidly, no organisation can afford to be complacent.

We’ve spent 20 years partnering with businesses across industries that rely on CyberOne’s expertise.

2. Cyber Threats Never Sleep

Sophisticated attacks operate 24×7 and threat actors often target businesses outside standard working hours. While Security Information and Event Management (SIEM) and Security Orchestration, Automation and Response (SOAR) platforms can automate parts of the defence, human expertise is critical for interpreting alerts, responding appropriately and effectively.

An MDR service ensures continuous monitoring by expert analysts, supported by advanced tools like Microsoft Sentinel and Microsoft Defender XDR. This combination of human intelligence and cutting-edge technology offers businesses the peace of mind that threats are being managed around the clock.

3. Eyes on Screen 24×7 Are Essential

Automated systems can only take your defences so far. A skilled analyst is needed to validate and act on every SIEM-generated alert. Without expert intervention, organisations face the dual risks of missing genuine threats or wasting resources on false positives.


Our experience has shown that combining real-time monitoring with proactive threat hunting significantly reduces incident response times. CyberOne’s approach aligns with best practices like Zero Trust principles, providing automation and human expertise to ensure rapid and accurate threat management.

4. Stopping a Breach in Its Tracks

Detecting and containing a breach as quickly as possible is critical, the average time to identify and contain a breach is 280 days and delays can lead to significant financial and operational losses.

With an MDR service, organisations gain access to a high-functioning Security Operations Center (SOC) capable of:

  • Containing threats before they escalate
  • Stopping lateral movement within the network
  • Preventing sensitive data from being infiltrated

As a Microsoft Advanced Specialisation partner in Threat Protection, we leverage tools like Defender for Endpoint and Sentinel to identify and neutralise threats within the “golden hour,” minimising damage and downtime.

5. The Business Impact of a Breach

The cost of a data breach goes far beyond fines or lost revenue, reputational damage, operational disruption, and regulatory penalties can have long-term consequences for businesses. A single breach can result in:

  • Financial losses from fines and legal fees.
  • Regulatory penalties for non-compliance with laws like GDPR
  • Loss of customer trust and brand reputation.
  • Downtime, which disrupts operations and reduces productivity

With 20 years of experience in managed security and over 250 global customers, we’ve seen firsthand how investing in proactive defences, like MDR, helps organisations avoid these outcomes.

6. Beyond Prevention: Recovery and Lessons Learned

Cyber security isn’t just about preventing attacks—it’s about learning and improving after an incident. A robust MDR service includes:

  • Incident post-mortems to strengthen defences.
  • Updating security playbooks to adapt to emerging threats.
  • Proactive alignment with frameworks like NIST CSF.

Our work with Microsoft technologies ensures that organisations not only recover but emerge stronger, with measurable improvements in their Secure Score and overall resilience.

Conclusion

In today’s world, cyber security is not just about having the right tools but combining technology, expertise and continuous vigilance. Whether you’re a small business just starting your cyber security journey or an enterprise looking to optimise your defences, MDR is no longer optional—it’s essential.
