Cyber threats are becoming more sophisticated and persistent, making it increasingly important for organisations to invest in robust security measures. A key component of a modern cybersecurity framework is the Security Operations Centre (SOC). When it comes to establishing a SOC, businesses often face a critical decision: should they build a physical, on-premise SOC or opt for a virtual SOC delivered remotely?
In this blog, you’ll gain a clear understanding of what a SOC is, the differences between on-premise and virtual deployments, the advantages and disadvantages of each model, and how to determine which approach is best suited to your organisation’s needs. We’ll also provide a set of criteria to guide your decision-making and explain how Rewterz can support you in deploying the right solution.
What Is a Security Operations Centre (SOC)?
A Security Operations Centre (SOC) is a dedicated unit responsible for defending an organisation’s information systems against cyber threats. It acts as the central hub for security monitoring, threat detection, incident response, and compliance management. Staffed by skilled cybersecurity professionals, a SOC operates continuously—often 24/7—to identify and respond to threats in real time.
SOC teams use a variety of advanced tools and technologies, such as Security Information and Event Management (SIEM) systems, threat intelligence platforms, and endpoint detection and response (EDR) solutions. Whether managed in-house or outsourced, the SOC’s mission is to reduce the time it takes to detect and mitigate threats, minimising damage and ensuring business continuity.
What Is an On-Premise SOC?
An on-premise SOC, also referred to as a physical SOC, is a dedicated security operations facility located within the organisation’s own infrastructure. The organisation is responsible for staffing, equipping, and managing this centre with internal cybersecurity experts. These professionals use in-house systems and policies to continuously monitor the network, investigate threats, and respond to incidents.
Organisations that opt for an on-premise SOC often do so because it gives them full control over their cybersecurity environment. All hardware, software, and data remain on-site, allowing for complete oversight of systems and processes. This level of control is especially important in industries that have strict data governance or regulatory compliance requirements.
A physical SOC can also be highly customised. Security tools, monitoring workflows, and response procedures can be tailored to the organisation’s specific needs, including the integration of legacy systems and proprietary platforms. However, this level of control and customisation comes at a cost. Establishing and maintaining an on-premise SOC requires significant capital investment in infrastructure, tools, and skilled personnel.
Additionally, managing a physical SOC places a heavy burden on internal teams. They must stay on top of patch management, upgrades, and continuous monitoring—responsibilities that can strain resources, especially in the face of a cybersecurity talent shortage. Scaling an on-premise SOC to meet growing needs is also time-consuming and expensive, as it often involves expanding physical space and hiring additional staff.
What Is a Virtual SOC?
A virtual SOC (vSOC) delivers all the core functions of a traditional SOC—such as monitoring, detection, incident response, and compliance—but it does so remotely. Instead of building a physical facility, organisations subscribe to SOC services from a managed security service provider (MSSP) like Rewterz. The provider’s cybersecurity experts operate from an off-site location, using cloud-based tools and platforms to protect the client’s environment.
One of the primary advantages of a virtual SOC is cost-effectiveness. Because the infrastructure and personnel are managed by the provider, organisations can avoid the large upfront capital investment associated with physical deployments. Instead, they pay for the services they need, often through a monthly subscription model, which makes budgeting more predictable.
Virtual SOCs are also quicker to deploy. Rather than spending months setting up infrastructure and hiring staff, organisations can onboard a vSOC provider within weeks. This makes the model particularly attractive for businesses that need rapid security improvements or are responding to regulatory requirements.
Furthermore, a vSOC provides access to a broader and more diverse pool of cybersecurity talent. Service providers often employ teams of experts with specialised skills and global threat intelligence capabilities. This enables businesses to benefit from continuous monitoring, advanced analytics, and real-time threat detection without having to recruit and retain those experts themselves.
However, there are trade-offs. Virtual SOCs may not offer the same level of customisation as an on-premise deployment, particularly for organisations with complex or unique security environments. There can also be concerns about data privacy and sovereignty, especially if sensitive data must cross borders or be stored in third-party cloud environments. Additionally, some companies may prefer the immediacy of having their security team physically present, particularly during critical incidents.
Which Model Is Better for Your Organisation?
The choice between a virtual and an on-premise SOC depends largely on your organisation’s size, industry, internal capabilities, and strategic goals. For large enterprises with robust IT teams and significant compliance demands, an on-premise SOC may be the better fit. These organisations often value the ability to control every aspect of their security environment and are more likely to have the resources needed to maintain such a complex operation.
On the other hand, small to mid-sized businesses, or those with limited cybersecurity personnel, may find that a virtual SOC offers the ideal combination of affordability, scalability, and expertise. These businesses often need to act quickly to address growing threats and regulatory requirements, and a vSOC allows them to do so without the delays and costs associated with building a physical facility.
Even for enterprises, a hybrid model may be attractive—maintaining an internal security presence while outsourcing some functions to a virtual SOC to augment their capabilities and reduce costs.
How to Choose Between Virtual and On-Premise SOCs
To determine the best fit for your organisation, it’s important to evaluate your specific needs and constraints. Begin by considering your budget: can your organisation support the capital and operational costs of a physical SOC, or would a subscription-based virtual model be more feasible?
Next, assess the complexity of your threat landscape. If your organisation faces sophisticated, targeted attacks or operates in a highly regulated environment, an on-premise SOC might offer the necessary control and depth. However, if you need rapid deployment, flexibility, and access to advanced tools without a significant upfront investment, a virtual SOC is likely the better choice.
Scalability is another key factor. If you anticipate rapid growth or fluctuating security needs, a virtual SOC provides the agility to scale services up or down as required. Conversely, an on-premise SOC may require considerable investment to expand.
You should also consider your internal capabilities. Do you have—or can you attract and retain—the specialised talent required to run a SOC 24/7? If not, outsourcing to a provider with a dedicated, experienced team can be a more effective approach.
Data privacy and compliance concerns must also be taken into account. Some organisations may be subject to data sovereignty laws or industry-specific regulations that necessitate on-premise control over certain data or systems. Finally, think about your existing infrastructure and integration needs. A virtual SOC must be able to integrate seamlessly with your systems, or you may find yourself facing compatibility challenges.
Security Operations Centres are essential for detecting and responding to modern cyber threats. Both on-premise and virtual SOCs offer compelling advantages, and the best choice depends on your organisation’s size, sector, resources, and risk profile. On-premise SOCs provide greater control and customisation but come with high costs and complexity. Virtual SOCs offer flexibility, affordability, and rapid deployment, making them an attractive option for many organisations.
Choosing the right model is a strategic decision that should align with your overall cybersecurity goals. If you’re uncertain about which SOC model is right for your business, expert guidance can make all the difference.
