SIEM - Log Ingestion and Management

SIEM - Bigger, Faster, Smarter Cybersecurity

Collecting, Analyzing, and Making Security Data Actionable

Open Systems, a Microsoft Gold Partner, leverages Microsoft Sentinel. Sentinel collects over ten petabytes of security data per day from nearly all their customers worldwide and is one of the world’s most complete SIEMs. The security data we collect from our customer environments is analyzed using AI against that security data to provide a comprehensive threat analysis. When it comes to detecting threats with AI, the more SIEM reference data, the better.

Cloud-scale Insights

When a new threat is identified at one customer, it’s categorized quickly to help protect other customers worldwide from the same threat. Threat data is also correlated and enriched with contextual data and includes feedback from security analysts, making threat assessments and alerts more actionable while continually improving the detection and remediation process.

Data-Driven Outcomes

Our SOC services collect and normalize immense amounts of security logs, system logs, audits, control console logs, alerts, and other threat information in real-time. Relevant data is ingested by high-speed SIEM query engines that sort through millions of records in seconds to provide our SOC engineers with meaningful threat assessments – quickly. Our security experts analyze and prioritize alerts and work with our customers to stop threats before they get started.

More is Better

Existing threat libraries are immense and continually grow so that known threats that enter an environment are easily detected. Security repositories also have known threat remedies to hasten containment and remediation.

Security data is stored and maintained to trace the origin of a security threat back to the root cause. Data retention is required to comply with legal hold mandates and support compliance requirements and audits. Search criteria and inspection engines parse through current and historical data, to help determine the root cause of threats and aid in implementing future security safeguards.
