Software that enables IT security analysts to detect and respond to threats is the core function of security event and information (SIEM) software. This software platform functions by gathering and integrating information from all assets on the organization’s network such that the information can be presented in a user interface to identify potential threats, also known as indicators of compromise (IoC).

In a 2020 survey of cybersecurity professionals conducted by Cybersecurity Insiders, 75% of respondents believed that SIEM is very important or extremely important to their organization’s security posture. Respondents listed the top three benefits to SIEM as: faster detection and response, better visibility, and more efficient security operations.

SIEM solutions are a combination of legacy IT security resources: Security Event Management (SEM) software and Security Information Management (SIM) software. By combining these two tools, IT security professionals are empowered with real-time incident monitoring, threat detection, and additional features that enable prompt analysis and reaction by security staff.

Common deployment of a SIEM solution was commonly on servers within the organization’s data center. In this environment, management of the hardware and software is usually the responsibility of local IT staff.

Effectively protecting your data from cyber threats demands a combination of deep technical security experience as well as up to date knowledge about online threats. This responsibility has been assigned to internal resources. Cybersecurity expertise is a must if you want to keep your organization safe from cybercriminals and online attacks.

SIEM platforms are inherently complex and require a great deal of experience spanning multiple system vendors, multiple device types, network and telecommunications topologies, computer and server operating systems, protocols, and much more.


Regulatory compliance with Gramm Leach Bliley Act, HIPAA, Sarbanes Oxley Act, and PCI DSS are required based upon the type of business operations your organization conducts.

  • The Gramm Leach Bliley Act, also known as the Financial Services Monetization ACT, applies to US financial institutions and governs the handling of private personal information.
  • The Health Insurance Portability and Accountability Act (HIPAA) was developed to protect the privacy and security of an individual’s health information.
  • The Sarbanes-Oxley Act of 2002 (SOX) is a United States federal law which sets standards for all U.S. public company boards, management and public accounting firms and includes data protection.
  • Payment Card Industry Data Security Standards (PCI DSS) mandate that all organizations that accept, acquire, transmit, process, or store cardholder data must take appropriate steps to safeguard customer information.

SIEM System Ownership and Responsibilities

In many cases, organizations can’t handle or don’t want to assume the entire responsibility for implementing and managing the complex SIEM solution along with all cybersecurity monitoring tasks.  However, you might not want to give a third-party company complete control over your cybersecurity. And, without an intimate understanding of your organization’s networks and standard operating procedures, the application of technology and manpower may fall short. Many feel the best option in a situation such as this is to consider (Co) Managed SIEM.

More than half of StratoZen clients have migrated from unsuccessful self-deployed SIEM attempts.  In each case, the client underestimated the time, effort, and expertise needed to stand up and manage an on-premise, in-house SIEM solution.  Each were told by the SIEM vendor that their solution would be simple and easy to deploy with little to no additional impact on their technical staff. The fact is, SIEM systems are complicated and require specialized technical knowledge to deploy and maintain.  A project and program of this complexity and critical importance should not be underestimated. Failure to properly implement and manage will create an otherwise avoidable liability to the organization. It will also result in significant extra work for your security and IT teams. The resulting damage to brand and balance sheet could cost hundreds of thousands of dollars more each year.

(Co)Managed SIEM

On-premise hosting by the client requires data room space and server availability or new hardware purchase. Management of the hardware can be handled by the client or a third-party provider.

Managed SIEM is a dedicated instance solution that can be deployed anywhere. Some common scenarios are where a client wants to host the platform themselves or have StratoZen build them an off-site instance. Hoff-site, or hosted SIEM is commonly deployed in Amazon Web Services (AWS) or Azure, removing the space allocation, power cost, maintenance, and capital investment from the client’s list of responsibilities.

With StratoZen (Co)Managed SIEM, we take over the management, monitoring, and
maintenance of your SIEM as if it were our own while your team maintains administrator access. You decide how much your team wants to learn versus how much you want to outsource to our cyber security experts who focus on SIEM. We can manage the entire system or share any responsibilities with your team as you see fit. We call it (Co)Managed as this is a team approach. We handle most or all day-to-day operations of your SIEM environment remotely, ensuring that your platform stays up to date and healthy. We also continuously perform rule and alert tuning to minimize false positives and provide custom rule enrichment including response / remediation assistance.

The StratoZen Security Advantage

StratoZen offers custom tailored SIEM services and solutions to address the cyber security needs of your organization and ensure that your SIEM solution provides the highest level of value and security.

Common challenges that we alleviate include:

  • Alert fatigue
  • SIEM complexity
  • Staff supplementation
  • Data privacy
  • Capital cost reduction

Alert Fatigue
Alert, or alarm, fatigue occurs when system operators are exposed to frequent and large numbers of alerts, thereby desensitizing them. This can lead to response delays or even failing to recognize significant events.

SIEM Complexity
A SIEM system is not as simple as plug-and-play. And, off the shelf systems can leave an organization vulnerable to otherwise avoidable threats.

Staff Supplementation
With (Co)Managed SIEM, StratoZen cybersecurity experts can take some or all fo the workload off of your staff level demand.

Data Privacy
StratoZen knows the current compliance regulations, can implement strategies to meet and exceed those guidelines as they apply to your organization. This removes non-compliance liability.

Capital Cost Reduction
BY choosing a hosted, (co)managed solution, your organization can reduce or eliminate significant initial capital investment. Likewise, ongoing expenses are also kept in check, resulting in a budget-friendly, predictable overall cybersecurity protection program.

By allowing StratoZen to (co)manage your SIEM, your internal staff can focus on managing the network and incident response rather than keeping the SIEM environment running and healthy. It’s your SIEM, customized to your processes and operations, managed by StratoZen’s unmatched expertise.
