In-House vs Managed SOC: Which Is Right for You?
We’re seeing cyberattacks grow in frequency and complexity. The need for round-the-clock security monitoring has never been more critical for businesses. However, deciding whether to build an in-house Security Operations Centre (SOC) or outsource to a managed SOC service provider can feel like a daunting choice.
This decision isn’t just about using the latest tech, it’s about operational, strategic, and financial implications as well as finding the right fit for your organisation’s goals, budget, and risk tolerance. As an IT leader or CISO, you must weigh the benefits of full control against the advantages of expert outsourced services.
In this article, we’ll be discussing the differences between an in-house SOC vs a managed SOC, the pros and cons of each option, and most importantly, how you can evaluate which is best for your business.
Key Takeaways
- In-house SOCs offer full control but come with high costs, staffing challenges, and lengthy setup times.
- Managed SOCs provide 24/7 expert monitoring with faster deployment, reduced overhead, and built-in compliance support.
- Cost and scalability are major advantages of outsourcing, with managed services available for as little as £5/hour.
- UK organisations are turning to MSSPs like DigitalXRAID to combat skills shortages and reduce alert fatigue.
- Hybrid SOC models can work — but only with clearly defined roles, especially during transitions to full outsourcing.
What Is a Security Operations Centre (SOC)?
A Security Operations Centre (SOC), also sometimes called a cybersecurity operations centre, is the nerve centre of your organisation’s cyber security posture. It’s a centralised team responsible for monitoring, detecting, investigating, and responding to cyber threats in real time. A SOC typically combines advanced technologies with skilled human expertise to ensure that your infrastructure and operations are protected 24/7.
The Role of a SOC in Cybersecurity
You just have to look at the news headlines to see that cyber threats are more sophisticated, persistent, and damaging than ever before. A SOC can help your business combat these risks by providing continuous visibility and fast response times.
Core Functions and Technologies Involved
A SOC ingests and correlates data from multiple sources, which can include firewalls, DNS, email gateways, databases, cloud platforms, and even third parties, to identify suspicious activity and mitigate attacks before they escalate.
The core technologies of a Security Operations Centre (SOC) include SIEM (Security Information and Event Management), SOAR (Security Orchestration, Automation, and Response), EDR (Endpoint Detection and Response), Asset Management, Intrusion Detection Systems (IDS) & Intrusion Protection Systems (IPS), Threat Detection, Threat Intelligence (CTI), Dark Web Monitoring, Continuous Vulnerability Monitoring and File Monitoring, to name just a few.
These tools enable the SOC team to detect, analyse, and respond to threats with speed and precision, providing you with:
- 24/7 threat monitoring and alert triage
- Incident response and digital forensics
- Proactive threat hunting
- Compliance and audit reporting (e.g. ISO 27001, NIS2)
- Vulnerability management and regular risk assessments
What Does an In-House SOC Look Like?
An in-house SOC is a security team built and managed internally by your organisation. This does give you full control, but also requires significant investment in infrastructure, skilled personnel, and time resource for deployment and management.
The cost to set up an in-house SOC that can monitor your infrastructure on a 24/7 basis is upwards of £500,000 per year. For many businesses, this isn’t achievable, either due to a lack of resource or a lack of interest in building out a full cyber security function that distracts from the core focus of your business.
Infrastructure and Staffing Requirements
The average salary of a security analyst in the UK is around £60,000 per year. When you factor in the need for a 24/7 operation with a full team of, realistically, at least 10 analysts, the cost can easily exceed £500,000 per year. This doesn’t even include the necessary tooling and ongoing training required to keep your SOC running, effective, and up-to-date.
Setting up an in-house SOC means sourcing and managing:
- Advanced technology platforms
- Secure physical or cloud infrastructure
- Skilled analysts, engineers, and SOC managers
- 24/7/365 staffing with shifts and holiday cover
Pros of an In-House SOC: Full Control, Internal Alignment
- Customise tools and processes to your exact needs
- Seamless integration with internal teams
- Direct governance over incident handling and data access
Cons: Cost, Complexity, Skills Shortage
Implementing an in-house SOC requires high CAPEX outlays, but this isn’t just about hiring the right people and buying the right tools. It requires a fundamental shift in business priorities, with a top-down focus on enhancing your organisation’s overall security posture. This might include ensuring compliance with regulations, developing incident response playbooks, running table-top exercises, and continuously updating your security strategies.
A self-managed SOC can also shift strategic focus away from core business goals, requiring leadership buy-in and significant changes to your business culture.
With a well-documented global cyber skills crisis, it’s very difficult for businesses to acquire and maintain in-house teams, especially as they battle with alert fatigue. The intense and high-pressure environment of a SOC can lead to burnout, making staff retention even more difficult.
What Is a Managed Security Operations Centre (Managed SOC)?
A Managed Security Operations Centre (Managed SOC) is an outsourced cyber security service delivered by a specialist provider, known as a Managed Security Service Provider (MSSP). You may also hear this called “SOC as a Service”. It offers the same or more advanced capabilities as an in-house SOC, but without the complexity, cost, and personnel retention issues.
How Managed SOC Services Operate
A managed SOC operates 24/7/365, staffed by highly certified analysts and SOC engineers. It continuously monitors your entire business environment, responds to threats in real-time, and provides you with reporting and threat intelligence that support your regulatory compliance and audit needs.
Pros: 24/7 Monitoring, Cost Efficiency, Expert Access
By partnering with a specialist MSSP, you get the benefits of a fully operational SOC without the associated costs and complexities.
- Lower Total Cost of Ownership (TCO): Partnering with an MSSP gives you immediate access to the expertise of a fully staffed and equipped SOC, without the need for a significant upfront investment. In fact, you can implement a managed SOC service for as little as £5 per hour.
- Access to Cutting-Edge Technology: Managed SOC providers invest heavily in the latest security technologies and tools. This includes advanced machine learning (ML) capabilities and generative AI models that enhance threat detection and response. You benefit from these technologies without the need for continuous investment, maintenance and upgrades.
- Speed, Scalability and Flexibility: A managed SOC can be deployed very quickly, with the guidance of seasoned experts to define design documents and understand what your most critical assets are. As your business grows and your cyber security needs evolve, a managed SOCscales and flexes to adapt quickly to your changing business.
- Focus on Core Business: By outsourcing SOC operations, you can focus on your core business activities, confident that your cyber security needs are in expert hands.
- Enhanced Compliance Support: Managed SOCs typically offer built-in support for key frameworks and regulations such as ISO 27001 and NIS2. With specialist knowledge of regulatory frameworks and audit requirements, a managed SOC ensures your organisation remains audit ready, without adding burden to your internal teams.
Cons: Vendor Dependence, Data Sharing Concerns
- You need a trusted, transparent partner with a clear SLA
- Some organisations may be cautious about outsourcing sensitive functions, although working with a CREST and NCSC accredited provider gives assurance
In-House vs Managed SOC: Key Differences
Here’s a breakdown to help guide your evaluation:
Cost and Resource Commitment
In-house: High setup CAPEX costs, recruitment, and retention challenges. Expensive tooling and 24/7 staffing required.
Managed: Subscription or tier-based pricing with tailored service options. Clear ROI and scalability.
Speed of Deployment and Scalability
In-house: 6-12+ months to stand up, especially with hiring and tool procurement.
Managed: Deployment in 4-6 weeks. Scales instantly with changing business needs.
Depth of Expertise and Coverage
In-house: Limited to internal team capability, difficult to keep pace with evolving threats.
Managed: 24/7 access to certified SOC analysts and threat hunters, with real-time updates to playbooks and tooling.
Compliance and Reporting Capabilities
In-house: Requires dedicated resources for audits, reporting, and policy management.
Managed: Built-in compliance support including ISO 27001 Certification and audit-ready reporting.
Which SOC Model Fits Your Organisation Best?
Every business is different, from size, to industry, to risk appetite. These are some of the key strategic considerations you must take into account when making a decision to build or buy your SOC:
SOC Cost Comparison
If you have budget flexibility and a strong security team, an in-house SOC might work. But for most UK organisations, a managed SOC offers lower and more predictable costs that scale with your business, and a stronger ROI.
SOC Staffing Challenges
If you have a strong existing in-house security team, it might make sense to optimise your resources to create your own security operations centre. However, if you have staffing challenges or shortages and are looking for an alternative solution, a managed SOC takes the operational challenge off your hands.
Regulatory Requirements and Sector Demands
If you’re in a highly regulated industry (such as finance, healthcare, or energy) you probably need fast, scalable compliance support. Managed SOCs align with standards like NIS2 and DORA by default.
Hybrid Options: Is There a Middle Ground?
There is a hybrid option when it comes to SOC, but it must be very clearly defined in order to work efficiently. Co-managed SOCs blend in-house oversight with external expertise. You do get control and compliance with less overhead. However, if roles and responsibilities aren’t clear, you could be at risk, both in terms of your business security and wasting money or resources. Our recommendation would be to only work on a co-managed SOC if you’re transitioning toward full outsourcing.
Why More UK Organisations Are Choosing Managed SOC
Addressing the Cybersecurity Talent Shortage
The global cyber skills shortage is a huge challenge which isn’t going to change in the short-term. Partnering with an outsourced Security Operations Centre ensures uninterrupted expert coverage without recruitment delays.
Reducing Alert Fatigue and False Positives
Managed SOC analysts reduce noise and enhance focus by combining advanced automation with human-led threat monitoring and detection. Real-time triage ensures they mitigate the most important high-fidelity alerts immediately.
