A security operations centre (SOC) is the team and tools that continuously monitor an organisation for cyber threats and respond to them. Whether you need 24/7 monitoring depends on your risk, but attacks happen at all hours, so round-the-clock coverage matters for many organisations. For those that cannot run a SOC in-house, managed detection and response provides the same continuous coverage.
What a security operations centre is
A security operations centre, or SOC, is the function responsible for continuously watching an organisation’s environment for signs of cyber threats and responding when they appear. It combines people, security analysts, with tools that collect and analyse security data, and processes for investigating and responding to what they find. The SOC is, in effect, the organisation’s security nerve centre: always watching, ready to act.
The core purpose of a SOC is detection and response. Prevention, patching, access controls, firewalls, aims to stop attacks. But no prevention is perfect, so detection and response exists to catch what gets through, and to act on it before it becomes a serious breach. The SOC is where that continuous watching and rapid response happen.
What a SOC actually does
A SOC carries out a set of ongoing activities. It monitors security data from across the environment, looking for signs of malicious activity. It investigates alerts to determine whether they represent a genuine threat. It responds to confirmed incidents, containing and remediating them. And it continuously improves, learning from what it sees to detect future threats better.
The value is speed and vigilance. Attacks unfold over time, and the sooner malicious activity is detected and acted on, the less damage it does. A SOC exists to shorten the gap between an attacker acting and the organisation responding, which is often the difference between a contained incident and a full-blown breach.
Why 24/7 matters
The question many organisations ask is whether monitoring needs to be around the clock. The uncomfortable answer, for many, is yes, and the reason is simple: attackers do not keep business hours. In fact, they often deliberately act outside them, at night, on weekends, over holidays, precisely because they know defenders may not be watching. An attack that begins on a Friday evening has all weekend to unfold if no one is monitoring until Monday.
This is why 24/7 monitoring matters. Detection and response are only effective if someone is actually watching when the attack happens. Coverage that runs only during business hours leaves large windows, evenings, nights, weekends, when an attacker can operate undetected. For an organisation with meaningful risk, those gaps are exactly where a serious breach can develop unnoticed.
Do you actually need it?
Whether your organisation needs 24/7 monitoring depends on your risk: what you have to protect, how attractive a target you are, and what a breach would cost you. An organisation holding sensitive data, operating critical services, or facing regulatory obligations generally needs continuous coverage, because the cost of an undetected breach is high and attacks can come at any time.
Smaller organisations with lower risk may reasonably start with less, but even they should be honest about the gaps that leaves. The trend across all sizes is toward continuous monitoring, because attacks are constant and the windows left by business-hours-only coverage are real. The right question is not whether round-the-clock monitoring would help, it almost always would, but whether the risk justifies the investment, and for many organisations it does.
The challenge of running a SOC in-house
Running a genuine 24/7 SOC in-house is demanding. It requires skilled security analysts, and enough of them to cover every hour of every day, which is expensive and hard given the shortage of security talent. It requires the tools to collect and analyse security data at scale. And it requires the processes and expertise to investigate and respond effectively. For many organisations, building and staffing all of this internally is simply not feasible.
This is the practical barrier: many organisations understand they need continuous monitoring but cannot realistically run a full SOC themselves. Fortunately, they do not have to.
Managed detection and response as the answer
For organisations that need continuous monitoring but cannot run a SOC in-house, managed detection and response provides the same outcome without the burden. It delivers 24/7 monitoring, investigation and response through an external team and platform, giving you continuous coverage without having to build and staff a SOC yourself.
This is how most organisations realistically achieve round-the-clock protection. Rather than the significant cost and difficulty of an in-house SOC, managed detection and response provides expert, continuous coverage as a service, scaled to your needs. It is often the most practical way to close the gaps that business-hours-only monitoring leaves, and to ensure that when an attack comes, at any hour, someone is watching and ready to respond.

Frequently asked questions
What is a security operations centre (SOC)?
A SOC is the function, combining people, tools and processes, responsible for continuously monitoring an organisation for cyber threats and responding to them. It is the organisation’s security nerve centre, focused on detection and response to catch what prevention misses.
What does a SOC do?
It monitors security data across the environment for signs of malicious activity, investigates alerts to identify genuine threats, responds to confirmed incidents by containing and remediating them, and continuously improves. Its value is detecting and acting on threats quickly, before they become serious breaches.
Do you need 24/7 monitoring?
For many organisations, yes, because attackers do not keep business hours and often act at night and on weekends when defenders may not be watching. Whether it is justified depends on your risk, but business-hours-only coverage leaves real windows for an attack to develop undetected.
How can you get 24/7 monitoring without a SOC?
Through managed detection and response, which provides continuous monitoring, investigation and response via an external team and platform. It delivers the same outcome as an in-house SOC without the significant cost and difficulty of building and staffing one yourself.
