Cyber attacks are only becoming more frequent, more sophisticated and more damaging than ever, leading to an increase in the need for managed detection and response (MDR) as a critical component your cyber security strategy. It’s not just about prevention anymore, it’s about detection, response and resilience. Learn why MDR is no longer optional in our recent blog post.
What is MDR?
Managed detection and response (MDR) is a fully managed cyber security service that combines advanced threat detection technologies with human-led investigation and response. Unlike traditional security tools that simply alert you to threats, MDR actively hunts, analyses, and neutralises them, 24/7.
At CSG, we deliver MDR through our trusted partner Sophos, a global leader in cybersecurity. Sophos MDR provides:
- 24/7 threat monitoring by expert analysts
- Proactive threat hunting to identify hidden risks
- Rapid incident response to contain and neutralise threats
- Detailed reporting and compliance support
- Integration with existing IT environments
This means your organisation is protected not just by software, but by a dedicated team of cyber security professionals. CSG recently celebrated our Sophos Platinum partnership, meaning we provide our customers access to the highest level of support, training and resources from Sophos, enabling us to deliver top-tier security solutions for our customers.
Not only are we Sophos Platinum partners, we also won Sophos Partner of the Year award, a statement to our dedication to providing the highest quality of cyber security services to our customers. The award took into consideration all partners across the UK and Europe, expressing our achievement.
Legal sector: protecting confidentiality and compliance
Law firms are built on trust, discretion and the ability to manage highly sensitive information. From contracts and case files to intellectual property and personal data, legal practices are custodians of information that cyber criminals are eager to exploit, putting emphasis on why MDR is no longer optional. Yet many firms, especially small to mid-sized practices, still rely on outdated or reactive cyber security measures.
Why MDR is urgent for the legal sector:
- The legal sector is a high-value target for cyber criminals due to the volume and sensitivity of the data it holds. Threat actors often use ransomware to lock firms out of their systems, demanding large sums to restore access.
- A breach can expose client communications, litigation strategies, M&A documents and confidential agreements, potentially leading to legal liability, regulatory fines and loss of client confidence.
- Law firms must comply with strict data protection regulations such as GDPR, SRA guidelines, and ISO standards. Failure to demonstrate adequate cyber security measures can result in disciplinary action, reputational damage, and loss of business.
- The rise of remote work, the introduction of AI in legal firms, cloud-based case management, and digital court systems has expanded the attack surface, making it harder for internal IT teams to monitor and secure every endpoint.
How MDR helps the legal sector:
- CSG’s MDR solution, powered by Sophos, delivers 24/7 threat detection, investigation and response, ensuring that any suspicious activity is identified and neutralised before it can escalate.
- Sophos MDR combines machine learning, threat intelligence and human-led analysis to detect even the most sophisticated attacks, including zero-day exploits, credential theft and insider threats.
- The service includes compliance-ready reporting, helping your firm demonstrate due diligence to regulators, insurers and clients.
- MDR also supports incident response planning, ensuring that if a breach does occur, your firm can recover quickly and minimise disruption to client services.
In a profession where reputation is everything, cyber security must be proactive, not reactive. With CSG and Sophos MDR, legal firms gain the confidence that their data, their clients, and their reputation are protected: 24 hours a day, 365 days a year.
Facilities services: protecting operational systems and client contracts
The facilities services industry is the backbone of safe, functional and efficient environments across commercial, industrial and public spaces. From building maintenance and HVAC systems to security, cleaning and energy management, these organisations manage a vast array of physical and digital assets, often across multiple sites and clients.
As the industry becomes more connected through IoT, smart building technologies, and cloud-based management platforms, the risk of cyber threats grows exponentially.
Why MDR is urgent for the facilities services sector:
- Facilities services companies are increasingly reliant on digital systems to manage access control, maintenance schedules, asset tracking, and client reporting. A cyber attack can disrupt these systems, leading to downtime, contractual breaches and safety risks, putting emphasis on why MDR is no longer optional within the facilities services industry.
- Many organisations in this sector handle confidential client data, including building blueprints, security protocols and service-level agreements (SLAs). A breach could expose sensitive information and damage long-standing client relationships.
- The industry often operates with mobile workforces, remote access tools, and third-party integrations, all of which expand the attack surface and make traditional perimeter-based security ineffective.
- Compliance with standards such as ISO 27001, Cyber Essentials, and client-specific security requirements is becoming a prerequisite for winning and retaining contracts, especially in government and corporate sectors.
How MDR helps the facilities services sector:
- CSG’s MDR solution, provides 24/7 monitoring and response across all endpoints, cloud environments and network infrastructure, ensuring that threats are detected and neutralised before they impact operations.
- Sophos MDR uses AI-driven threat detection and human-led investigation to identify unusual activity, such as unauthorised access to building systems or lateral movement across client environments.
- The service includes compliance-ready reporting, helping facilities services providers meet contractual obligations and demonstrate effective cyber security practices during audits and tenders.
- MDR also supports incident response planning, ensuring that if a breach occurs, the organisation can respond quickly, minimise disruption and maintain service continuity.
In an industry where uptime, safety, and client trust are non-negotiable, cybersecurity must be proactive. With CSG and Sophos MDR, you can protect your systems, your clients and your reputation, while continuing to deliver seamless, high-quality service across every site.
Charity sector: defending limited resources and donor trust
Charities and non-profits are driven by purpose, not profit, but that doesn’t make them immune to cyber threats. In fact, their limited budgets, reduced IT teams and high-value data make them attractive targets for cyber criminals. Whether it’s a local community organisation or a national charity, the consequences of a cyberattack can be devastating, not just financially, but operationally and reputationally.
Why MDR is no longer optional for the charity and not-for-profit sector:
- Cyber criminals are increasingly targeting charities, through strategies such as phishing scams, and they often lack the resources to implement robust cyber security. Attacks range from phishing and ransomware to business email compromise and donor fraud.
- A breach can expose donor databases, beneficiary records, volunteer information and financial systems, potentially violating GDPR and other data protection laws.
- The fallout from an attack can be severe: funding may be frozen, services disrupted, and public trust eroded, all of which directly impact the charity’s ability to deliver on its mission.
- Many charities rely on third-party platforms for donations, communications and service delivery. These integrations, while convenient, introduce additional vulnerabilities if not properly monitored.
- Cyber insurance providers are increasingly requiring evidence of active threat monitoring and response capabilities, something many charities struggle to provide without external support.
How MDR helps the charity and not-for-profit sector:
- CSG’s MDR solution delivers 24/7 threat detection, investigation, and response, ensuring that even the most resource-constrained charities are protected by a team of cyber security experts.
- Sophos MDR combines AI-driven threat intelligence with human-led analysis, detecting and neutralising threats before they can cause harm, whether it’s a phishing attempt targeting a fundraiser or ransomware aimed at donor databases.
- The service includes compliance-ready reporting, helping charities demonstrate due diligence to trustees, regulators and funding bodies.
- MDR is cost-effective and scalable, making it accessible to charities of all sizes. It removes the burden of building an in-house security team while delivering enterprise-grade protection.
- CSG works closely with charity clients to ensure the solution is suited to charity’s operational model, risk profile and regulatory obligations, providing not just protection, but peace of mind.
For charities, every pound counts, and every breach threatens more than just data. It threatens the ability to serve communities, support vulnerable people and deliver life-changing work. With CSG and Sophos MDR, charities can protect their mission, their people, and their future, while staying focused on what matters most: making a difference.

Accountancy sector: protecting financial data and client confidence
Accountancy firms are entrusted with some of the most sensitive data in the business world: financial records, tax filings, payroll information and confidential client communications. This makes them prime targets for cybercriminals seeking to exploit financial systems or steal identities.
Why MDR is urgent:
- Cyber attacks on accountancy firms are on the rise, with ransomware, phishing and business email compromise (BEC) among the most common threats. These attacks can lead to fraudulent transactions, data theft and regulatory breaches.
- Firms must comply with strict data protection regulations such as GDPR, HMRC guidelines and industry-specific standards. A single breach can result in hefty fines, legal action and loss of professional accreditation.
- The reputational damage from a cyber incident can be severe. Clients expect their financial data to be handled with the highest level of security. A breach can lead to client churn, loss of referrals and long-term brand damage.
- Many accountancy practices, especially small to mid-sized firms, lack the internal resources to monitor threats around the clock or respond effectively to incidents.
How MDR helps accountancy firms:
- CSG’s MDR solution, powered by Sophos, provides 24/7 threat detection, investigation and response, ensuring that any suspicious activity is identified and neutralised before it can cause harm.
- Sophos MDR uses AI-driven analytics and human-led threat hunting to detect even the most subtle signs of compromise, such as credential misuse, lateral movement or data exfiltration.
- The service includes compliance-ready reporting, helping accoutancy firms demonstrate due diligence to regulators, insurers and clients.
- MDR also supports incident response planning, helping accountancy firms recover quickly and minimise downtime in the event of a breach.
In a profession built on trust, accuracy and confidentiality, cybersecurity is not just an IT issue, it’s a business priority. With CSG and Sophos MDR, accountancy firms can protect their clients, their reputation, and their future, without the need to build an in-house security team.
