Building Modern Security Operations for the Public Sector with Sophos Taegis MDR
Public sector organisations are under unprecedented pressure to defend critical services against an evolving threat landscape, while operating within tight budgets and complex legacy environments. Traditional security operations models often fall short. East Lothian Council partnered with CyberLab to change that.
This success story explores how a leading Scottish local authority modernised its security operations capability with Sophos Taegis Managed Detection and Response (MDR), delivered and supported by CyberLab, to gain 24/7 threat visibility, faster incident response, and the operational predictability that public sector finance and service delivery demand.
Why the Public Sector Is a Prime Target for Cyber Threats
UK public sector organisations remain a high-value target for cyber criminals and nation-state threat actors.
The reasons are well documented:
- They hold vast amounts of sensitive personal data on residents, staff and service users.
- They deliver essential services where downtime has real-world consequences for communities.
- They operate complex digital estates with significant legacy infrastructure.
- They face increasing regulatory expectations under NCSC guidance, the Network and Information Systems Regulations, and sector-specific frameworks.
At the same time, public sector cyber security teams are routinely stretched. Recruiting and retaining specialist security analysts is difficult, particularly in regions outside major commercial hubs. Building a 24/7 internal Security Operations Centre is rarely viable, either operationally or financially. This combination of high target value and limited internal resource makes Managed Detection and Response one of the most effective ways for local authorities to elevate their security posture quickly and sustainably.
About East Lothian Council
East Lothian Council is the Scottish local authority responsible for delivering essential public services across East Lothian, supporting thousands of residents, communities and businesses. As part of its ongoing digital transformation programme, the council operates a growing and increasingly interconnected digital estate, with a clear commitment to maintaining service availability, protecting sensitive information and upholding public trust.
As cyber threats targeting the public sector have grown in sophistication, the council recognised that traditional perimeter-based defences were no longer sufficient. A modern, proactive security operations capability was required to keep pace with the threat landscape and protect the critical services East Lothian residents rely on every day.
The Business Challenge: Visibility, Speed and Operational Readiness
Before partnering with CyberLab, East Lothian Council had a clear set of operational priorities. The council needed to enhance its ability to detect, investigate and respond to cyber threats around the clock, across a diverse and complex IT environment.
The specific challenges were:
- Real-time visibility of malicious activity across the entire digital estate.
- Faster response capability to potential threats, with reduced time from detection to containment.
- Always-on security operations, beyond the working hours of an internal IT team.
- Speed of procurement and implementation, with the ability to assess, procure and deploy an advanced MDR solution within short timescales.
- A partner with deep public sector understanding, capable of supporting rapid deployment without disrupting essential services.
- Predictable total cost of ownership, with clear and consistent budgeting for long-term security operations.
The council needed a solution that elevated its threat monitoring and incident response capability, while respecting the unique operational and financial constraints of a local authority.
Why Sophos Taegis MDR Was the Right Fit for the Public Sector
Working closely with the council’s security and infrastructure team, CyberLab assessed the available Managed Detection and Response options against East Lothian Council’s specific requirements. Sophos Taegis MDR was selected as the foundation for the council’s modernised security operations capability for several reasons.
First, it delivers true 24/7 threat detection, investigation and response. Sophos security analysts work alongside CyberLab’s team to monitor activity continuously, investigate alerts at depth, and contain threats before they escalate. For a local authority that cannot staff an internal SOC around the clock, this is transformative.
Second, Sophos Taegis MDR delivers something traditional SOC and SIEM-based models often fail to provide: budget certainty. Many MDR or SIEM solutions are priced on data ingestion or consumption, leaving organisations exposed to unpredictable costs as activity grows. Taegis MDR offers a predictable total cost of ownership, with no ingestion tuning, no SIEM build complexity, and no surprise charges. For public sector finance teams managing fixed annual budgets, that predictability is essential.
Third, Sophos Taegis integrates broadly with existing security tools, helping the council maximise the value of investments already made and avoid wholesale replacement of working technology.
The CyberLab Approach
CyberLab supported East Lothian Council through every stage of the project, combining technical expertise with a deep understanding of public sector procurement, governance and operational realities.
Rapid Procurement and Proof of Concept
The council operated under a short procurement window. CyberLab accelerated the process through a structured proof of concept, demonstrating Taegis MDR’s capability against the council’s specific environment and use cases. This allowed informed decision-making at pace, without the delays often associated with public sector technology procurement.
Deployment and Configuration
Once selected, CyberLab fully deployed and configured Sophos Taegis MDR across the council’s environment. Integration was tailored to the council’s existing security tools, maximising coverage while avoiding duplication of capability.
Seamless Onboarding
Public sector environments cannot tolerate operational disruption. Schools, social care, planning, refuse collection and dozens of other critical services depend on the digital estate. CyberLab designed the onboarding process to be seamless, transitioning the council into a fully managed MDR operation without interruption to live services.
Ongoing Strategic Support
Beyond deployment, CyberLab continues to provide strategic support and guidance tailored to public sector challenges. The relationship is consultative by design, with CyberLab acting as an extension of the council’s internal security team rather than a transactional vendor.
The Outcome: Greater Confidence, Stronger Defences
The implementation of Sophos Taegis MDR has materially strengthened East Lothian Council’s security operations capability. With real-time threat insights, expert analyst guidance and streamlined incident response, the council can focus on delivering essential services with greater confidence.
The key outcomes the council has realised include:
- Improved threat visibility, providing deeper situational awareness across the digital estate.
- Increased confidence in response capability, supported by expert MDR analysts working 24/7.
- Rapid and effective deployment, enabling operational protection in a short timeframe.
- Reduced operational strain, with CyberLab acting as an extension of internal security staff.
- Proactive vigilance and early threat identification, strengthening the council’s overall security posture.
- Predictable long-term operational costs, providing the budget certainty public sector teams need.
The partnership has enabled East Lothian Council to modernise its approach to security operations and adopt a robust, future-ready MDR foundation that supports a more resilient digital infrastructure for the communities it serves.
In the Council’s Own Words
“East Lothian Council has been working closely with CyberLab to strengthen our security operations capability. Their support in implementing Sophos Taegis as our managed detection and response solution provided significantly improved visibility of threats across our environment and increased confidence in our ability to respond swiftly and effectively.
The procurement process and proof of concept were progressed at an impressive pace, with CyberLab able to facilitate rapid turnaround and accommodate short-notice requirements without disruption. They provide added value through proactive vigilance, consistently practical support, and a genuine understanding of local authority challenges.

Key Takeaways for Public Sector Leaders
For council CIOs, Heads of IT and security leaders considering how to elevate their security operations:
- MDR removes the need to build an internal SOC, giving public sector teams 24/7 capability without the recruitment burden.
- Predictable pricing matters. Avoid consumption-based MDR models that expose council budgets to unpredictable variance.
- Procurement speed is achievable. With the right partner, even complex MDR deployments can be assessed, procured and operational quickly.
Public sector understanding is essential. Choose a partner who understands legacy environments, service availability constraints, and the realities of local government operations.
