Security Operations Centre: Enhanced Cybersecurity for Your Organisation
Cyber threats don’t follow working hours, and most organisations lack the resources to monitor and respond continuously.
A Security Operations Centre (SOC) is the function responsible for detecting, analysing, and responding to cyber threats across your environment.
It brings together people, processes, and technology to provide ongoing visibility, reduce risk, and support fast, structured security incident response when issues arise.
What Are Managed SOC Services (SOCaaS)?
A managed SOC delivers these capabilities as an outsourced service, without the cost of hiring an in-house team.
Instead of recruiting, you gain access to experienced cyber security analysts, maintaining 24/7 coverage, established processes, and advanced tooling.
Evalian’s UK-based SOC as a Service integrates with your existing environment to provide continuous monitoring, threat detection, and rapid response.
“I have used multiple security partners over the years, but finally feel I’ve found one I can rely upon for multiple cyber services. Every consultant we worked with is an industry-leading expert, and this is backed up by exceptional and responsive account management.” – Thomas Turner, Head of IT Infrastructure, Asta Capital
“Most organisations choose a managed SOC because running one internally is difficult to sustain. Recruitment is slow, costs are high, and maintaining coverage is challenging. A managed model provides immediate capability, predictable cost, and consistent coverage.” – Matt Gerry, Head of Cybersecurity
Ongoing training to keep pace with evolving cyber threats
Most organisations struggle to maintain this effectively.
A managed cyber SOC provides immediate access to expertise, scalable coverage and faster implementation.
What does a managed SOC do?
A managed SOC provider handles:
24/7 Security monitoring across endpoints, networks, & cloud
Detection of suspicious activity using SIEM & XDR
Incident triage & response
Ongoing threat hunting to identify hidden risks
Reporting aligned to compliance & governance requirements
Automated response & workflow orchestration
In practice, many organisations adopt a co-managed or fully managed SOC model, depending on internal capability.

Who Is A Fully Managed Or Co-Managed SOC Service For?
Our SOC is ideal for organisations across a wide range of critical industries, whether you need a managed SOC for financial institutions, healthcare, education, leisure and transport, and professional services such as legal and insurance.
These sectors face increasing pressure to protect sensitive data, maintain operations, and demonstrate resilience against sophisticated cyber threats. While each industry has unique risks and compliance drivers, they all share a common challenge: the need for 24/7 threat monitoring and response.
Our service is designed to support the needs of CISOs, Heads of IT and Risk, Information Security Managers, and Compliance Leads who are responsible for safeguarding their organisation’s systems and data.
Whether you’re aiming to meet regulatory standards like ISO 27001, NIS2, or Cyber Essentials, reduce alert fatigue, or gain clearer visibility into your threat landscape, we work as an extension of your internal team, helping you detect, respond and report on threats with confidence and clarity.
“Threats are more targeted, persistent, and harder to detect. Advanced Persistent Threats (APTs), phishing campaigns, and credential abuse often bypass traditional controls.
A managed SOC shifts you from reactive security to continuous detection and response.”
Kristen Kadach, Security Operations Lead
Key Benefits Of Managed SOC Services
Detect & Respond To Threats Around The Clock
Continuous monitoring ensures that threats are identified as soon as they emerge, not after the damage is done. With defined response processes, incidents are investigated and contained quickly, reducing impact and improving overall resilience.
Reduce The Cost Of Building & Running A SOC
Building an in-house SOC means significant investment in people, tools, and 24/7 coverage. A managed SOC reduces costs, giving you enterprise-level security operations without the overhead of hiring, training, and ongoing infrastructure.
Reduced Alert Fatigue & Improved Efficiency
A managed SOC filters and prioritises alerts, allowing your team to focus on real threats. This reduces noise, improves efficiency, and supports robust compliance with your organisation's standards such as GDPR and ISO 27001 through structured reporting.
Access To Experienced SOC Analysts

What are managed SOC services?
Managed SOC services provide outsourced security operations, including 24/7 monitoring, threat detection, and incident response. A managed security operations centre combines technology such as SIEM and XDR with experienced security analysts to identify and respond to cyber threats in real time.
Why use a managed SOC service?
Most organisations lack the resources to operate a 24/7 SOC internally. A managed SOC provides continuous monitoring, faster incident response, and access to specialist expertise without the cost of building and maintaining an in-house team.
How does a managed SOC work?
A managed SOC collects and analyses security data from across your systems using SIEM and XDR tools. Security analysts investigate alerts, prioritise incidents, and respond based on defined playbooks. This includes containment, remediation, and ongoing monitoring.
What types of threats can a managed SOC protect against?
A managed SOC helps detect and respond to threats, including phishing attacks, ransomware, credential compromise, insider threats, and advanced persistent threats (APTs). It also identifies misconfigurations and unusual behaviour that may indicate early-stage attacks.
What tools are essential in a managed SOC?
Effective SOC managed services rely on a combination of:
SIEM (Security Information and Event Management) for log analysis
XDR (Extended Detection and Response) for endpoint and network visibility
Threat intelligence platforms
Automation and orchestration tools (SOAR)
These tools enable faster detection and a more consistent response.
Do I still need an internal security team if I use a managed SOC?
Yes. A managed SOC complements your internal team rather than replacing it. Your team remains responsible for governance, risk decisions, and business context, while the SOC handles monitoring and response.
Can a managed SOC replace my existing security team?
No. It reduces operational burden but does not replace internal ownership of security strategy, compliance, and decision-making.
What's the difference between SOC, SIEM and MDR?
Here’s a breakdown of the differences between SIEM (Security Information and Event Management – a platform for real-time analysis of security alerts.), MDR (Managed Detection and Response), XDR (Extended Detection and Response – tools for intrusion detection and prevention, endpoint protection, and network security) and SOC, explaining how each supports threat detection, response, and visibility.
From SIEM’s log correlation to MDR’s managed response, XDR’s integrated protection and the 24/7 coverage of a SOC, it helps you understand how these capabilities fit together to strengthen your security posture.

Organisations wanting external expertise to respond to threats
Organisations wanting unified view of modern attack surface
Organisations wanting 24/7 cover, centralised security team
Evalian’s SOC service uses SIEM and EDR to provide a managed SOC and MDR service.
What’s the difference between a managed SOC and an MSSP?
An MSSP (Managed Security Service Provider) typically delivers predefined security services such as firewall or endpoint management. A managed SOC provides continuous monitoring, threat detection, and active incident response, making it more focused on real-time threat management.
How much does a managed SOC provider cost in the UK?
SOC setups vary widely from one organisation to another. Some choose to build a fully in-house SOC, others outsource the function entirely, and many operate a hybrid or co-managed model.
In-house SOC: offers greater control but comes with significantly higher costs.
Outsourced SOC / SOCaaS: more cost-effective and scalable.
Hybrid / co-managed: balances control and cost.
If you’re still weighing your options, it’s important to understand the benefits of each approach, the initial investment required, and the ongoing costs needed to ensure your SOC delivers real value for your budget.
Implementation usually takes a few weeks. This includes onboarding systems, configuring monitoring tools, and aligning response processes with your environment.
How quickly do managed SOC providers respond to incidents?
Response times depend on SLAs, but critical incidents are typically investigated within minutes. Effective SOC services prioritise high-risk alerts to reduce impact quickly.
