Introduce your SIEM to the most effective threat detection and response solution available. 

SIEM Security Solutions: Achieve optimal security and business performance

Security Information and Event Management (SIEM) systems are complex, making them difficult to optimize and maintain for comprehensive compliance and security monitoring. In fact, 80% of organizations recently surveyed experienced a security breach in the past two years, and 53% of respondents stated that their SIEM solution was ineffective in detecting or responding to the breach.1 

Critical Start SIEM Security Solutions helps you reach the full operating potential of your SIEM investment for threat detection and response by maximizing value, maintaining compliance, closing security gaps, increasing security maturity and mitigating risk. 

Stay ahead of cyberthreats without breaking the bank 

Accelerate the return on your SIEM investment

Get the highest combined value between log sources and threat detections. Our experts help you prioritize your ingest data and tune log sources to drive threat detection and enrich content needed for investigations.

Reduce the noise

Boost efficiency and productivity by reducing false positives. We ingest high-fidelity data sources into ZTAP®, our Zero Trust Analytics Platform™, which looks for known good behaviors first before sending the potentially threatening alerts to our SOC analysts for further investigation. 

Improve security posture & minimize risk

We map your threat detection content and validate MITRE ATT&CK® Framework coverage to ensure relevance as new security initiatives arise. 

Boost SOC productivity & efficiency

Offload Tier 1 and Tier 2 SOC support and let us do all the heavy lifting. The combination of our ZTAP and seasoned  SOC and Threat Detection Engineering teams frees up your time to keep your business safe

Maximize breach reduction

Keep moving forward on your security maturity journey with full transparency into your data and detections, backed by dashboards that measure KPIs, ensuring the best ROI per dollar invested.

Integration with the leading security tools

Our MDR services integrate with SIEM tools from the following vendors:

Rest assuredwe’ve got your back

From onboarding through maturity, we’re with you every step of the way.

Onboard and Personalize 

  • We use a proven process to get you up and running as fast as possible so you begin to realize value in a matter of days. 

  • Onboarding is just the beginning. We continue to add value to your implementation by confirming your SIEM is working effectively, ensuring the highest fidelity of your log sources through configuration and tuning and creating playbooks adapted to your environment to reduce false positives. 

  • The total onboarding/personalizing process normally takes 4-6 weeks, depending on the SIEM tool you’re using. 

Investigate and Resolve

  • Our ZTAP seamlessly integrates with your SIEM platform to automate the investigation and triage of every alert across users, devices, applications and infrastructure. 

  • After you’re up and running, our seasoned security analysts will monitor your environment 24x7x365 for potential threats. (Expect an approximately 90% reduction in false positives on the first day of production monitoring!) 

  • We prioritize data based on what we have observed with other customers and MITRE ATT&CK® Framework coverage to mitigate risk and then use our trust-oriented approach to MDR to eliminate false positives at scale and streamline investigation and response processes, escalating less than 0.01% of alerts and reduce alert volumes by more than 99%. 

  • Your named Customer Success Manager will check in with you regularly and conduct Quarterly Service Reviews to ensure that, as your company evolves and changes, our services are still meeting your needs.  


  • Optimize your SIEM solution (and therefore your threat detection) with health and ingest cost analyses, zero-log ingest alerts, customization and configuration for a more efficient allocation of your resources. 

  • Simplify resource management and improve team efficiency by staying on top of current changes—even if your SIEM vendor is continuously updating your platform. We make sure your SIEM is up-to-date, address hotfixes and review any out-of-the-box content, allowing your analysts  
    to stay focused on real and emerging threats and help you avoid costly downtime. 


  • Effective response guidance requires investigation and correlation across multiple security tools, making it difficult for many businesses to realize the full operating potential of their SIEM for threat detection. We want to help you get the most out of your SIEM services, so we’re with you every step of the way to verify coverage and add more data sources as your business changes, such as cloud migration, bring your own device (BYOD) and multi-factor authentication. As your security ecosystem evolves and grows, we evolve and grow with you. 

  • Leverage contextual threat intelligence to make decisions that improve threat detection and response outcomes. 

  • Use custom and pre-populated dashboards to understand your threat resilience level and prove value to your business.
