What is managed SIEM?

Managed SIEM is an alternative to on-premise deployment, setup and monitoring of a SIEM software solution where an organization contracts with a third-party service provider to host a SIEM application on their servers and monitor the organization's network for potential security threats. Organizations choose managed SIEM for their corporate security needs to deploy faster, reduce setup and training costs and leverage the expertise of cyber security specialists.

Key takeaways

  • Managed SIEM is an alternative to on-premise deployment, setup, and monitoring of a SIEM software solution.
  • Organizations choose managed SIEM for their corporate security needs to deploy faster, reduce setup and training costs, and leverage the expertise of cyber security specialists.
  • When choosing whether to contract with a managed SIEM provider or MSSP, assess their overall service offerings to ensure you're getting good value-for-money and security coverage that complements the capabilities of your existing SecOps team.

Why managed SIEM?

Cyber security is a growing concern as the number of high-profile data breaches climbs yearly and even small and medium-sized organizations recognize a greater need to secure their IT assets against external threats. When it comes to deploying a SIEM tool, organizations can choose to set up and monitor an on-premise SIEM tool or contract with a third party for managed SIEM services.

About managed SIEM services

Several strategic benefits lead organizations to partner with a third-party managed SIEM provider, including:

Outsourced security expertise - managed SIEM providers focus on enterprise security as their primary value driver. They hold a wealth of cyber security expertise to enhance IT security for their customers.

Strategic partnerships - managed SIEM providers are well-connected within the cyber security industry, including with other major security technology vendors. This gives them access to more tools, resources and expertise, along with the latest innovations and timely alerts about the latest detected threats.

Reputation - a reputable managed SIEM provider that offers a proven track record of securing its clients from cyber attacks through effective setup and monitoring of security tools. Managed SIEM can give you peace of mind that industry-leading experts are managing your business security.

What are the benefits of managed SIEM?

The business case for managed SIEM centers on reducing costs and leveraging outsourced security expertise to help manage security operations and protect the business from cyber security threats and data breaches.

Reduced SIEM deployment costs

If an organization chooses to deploy a SIEM tool on-premises, it must purchase the IT infrastructure needed to support it. Purchasing additional IT assets to support a SIEM deployment can be expensive for small or medium-sized businesses. With managed SIEM, organizations pay a monthly subscription fee.

Streamlined daily security operations

Managed SIEM providers offer the core services of SIEM, such as security monitoring and incident response, but they can also take over tasks that your in-house SecOps team would normally be responsible for. Delivering monthly security reports, installing patches and updates, managing compliance, and maintaining the SIEM configuration and asset inventory functions can all be offered by managed SIEM providers.

Rapid deployment

Managed SIEM providers have existing infrastructure to facilitate your SIEM solution's rapid deployment. Instead of customizing your own SIEM deployment, you may consider partnering with a managed SIEM that has developed the know-how to deploy SIEM quickly and efficiently to start protecting your IT infrastructure.

Access to expertise

Leading managed SIEM providers maintain a skilled staff of cyber security experts that will collaborate to analyze your enterprise security logs, investigate incidents and provide threat detection and response services. Managed SIEM is a cost-effective alternative to recruiting, hiring, training and managing your team of cyber security experts.

Access to technology

Managed SIEM providers use industry-leading tools to offer customers the best security standard. These technologies might cost your organization hundreds or thousands of dollars to license annually, but your managed SIEM provider will implement them to protect your IT infrastructure as part of your normal subscription fee.

SIEM-as-a-Service

SIEM as a service is a collection of SaaS tools that provide real-time incident monitoring and threat detection. Using real-time correlation and data log analysis tools, SIEM as a service provides a centralized solution for automating your security log information and threat detection.

Managed security services vs. SIEM

What's the difference between a managed SIEM and a managed security service provider (MSSP)?

The most basic managed SIEM providers host your SIEM tool, coordinate the collection of security and event logs and report on the results. These providers may manage a centralized SIEM that monitors the networks of multiple customers, or they may choose to configure and manage individualized SIEM platforms for each of their customers.

An MSSP typically offers a greater variety and level of service. In addition to hosting and managing a SIEM tool, they may play a more prominent role in analyzing log data and investigating security threats. They may also offer an expanded suite of services, including anti-malware software and vulnerability scanning.

When choosing whether to contract with a managed SIEM provider or MSSP, the most important thing is to assess their overall service offerings to ensure you're getting good value-for-money and security coverage that complements the capabilities of your existing SecOps team.
