In response, SIEM vendors are developing advanced platforms that ingest more data, provide greater context, and deploy machine learning and automation capabilities to augment security analysts’ efforts. These solutions deliver value by giving security analysts deeper and broader visibility into complex infrastructures, increasing efficiency and decreasing the time to detection and time to respond.

Vendors offer SIEM solutions in a variety of forms, such as on-premises appliances, software installed in the customers’ on-premises or cloud environments, and cloud hosted SIEM-as-a-Service. Many vendors have developed multi-tenant SIEM solutions for large enterprises or for managed security service providers. Customers often find SIEM solutions challenging to deploy, maintain, or even operate, leading to a growing demand for managed SIEM services, whether provided by the SIEM vendor or third-party partners.

SIEM solutions continue to vie for space with other security solutions, such as endpoint detection and response (EDR), security orchestration automation and response (SOAR), and security analytics solutions. All SIEM vendors support integrations with other security solutions. Many vendors also offer tightly integrated solution stacks, allowing customers to choose the solutions they need most, whether just a SIEM, a SIEM and a SOAR, or some other combination. Other vendors are incorporating limited EDR- or SOAR-like capabilities into their SIEM solutions for customers who want the extra features but are not ready to invest in multiple solutions.

With so many options, choosing a SIEM solution is challenging. You will have to consider several key factors, starting with your existing IT infrastructure. Is an on-premises SIEM the right choice for you, or do you want a cloud-based or hybrid solution? Which systems and devices will be sending data to your SIEM, and how much data will it need to collect, correlate, analyze, and store? You should also consider the relative importance of basic capabilities and advanced features, bearing in mind that the basic capabilities may be considerably easier to deploy, maintain, and operate. Will your IT and security teams be able to deploy, maintain, and operate the solution on their own, or should you look for managed services to handle those tasks?

This GigaOm Radar report details the key SIEM solutions on the market, identifies key criteria and evaluation metrics for selecting a SIEM, and identifies vendors and products that excel. It will give you an overview of the key SIEM offering and help decision-makers evaluate existing solutions and decide where to invest.

SIEM solutions can be deployed on-premises, in the cloud, or a mix of the two. Deployment models must be weighed with regard to the environments the SIEM solution will protect. With more and more digital infrastructure and services becoming mission critical to every enterprise, SIEMs must handle higher volumes of data. Vendors and customers are increasingly focused on cloud-based solutions, whether SaaS or cloud-hosted models, for their scalability and flexibility.

The latest developments for SIEM solutions include machine learning capabilities for incident detection, advanced analytics features that include user behavior analytics (UBA), and integrations with other security solutions, such as security orchestration automation and response (SOAR) and endpoint detection and response (EDR) systems. Even though additional capabilities within the SIEM environment are a natural progression, customers are finding it even more difficult to deploy, customize, and operate SIEM solutions.

Other improvements include better user experience and lower time-to-value for new deployments. To achieve this, vendors are working on:

• Streamlining data onboarding
• Preloading customizable content—use cases, rulesets, and playbooks
• Standardizing data formats and labels
• Mapping incident alerts to common frameworks, such as the MITRE ATT&CK framework

Vendors and service providers are also expanding their offerings beyond managed SIEM solutions to à la carte services, such as content development services and threat hunting-as-a-service.

There is no one-size-fits-all SIEM solution. Each organization will have to evaluate its own requirements and resource constraints to find the right solution. Organizations will weigh factors such as deployment models or integrations with existing applications and security solutions. However, the main decision factor for most customers will revolve around usability, affordability, and return on investment. Fortunately, a wide range of solutions available in the market can almost guarantee a good fit for every customer.
