Cyberseer Managed SIEM Services is an outsourced security monitoring service that provides 24/7 threat detection, investigation, and response capabilities without requiring organizations to build an in-house Security Operations Center. The service operates on a platform-agnostic model, supporting multiple SIEM platforms including Google Cloud Security, Exabeam, and Microsoft Sentinel. The service combines automated workflows with certified Tier 3 security analysts who monitor, triage, and investigate security incidents. It collects and correlates log data from endpoints, cloud environments, identity systems, and networks to detect threats such as insider threats, cloud misconfigurations, phishing attempts, and advanced persistent threats. Key operational capabilities include real-time monitoring, proactive threat hunting, SOAR-ready playbook execution, and MITRE ATT&CK-aligned detection rules. The service provides compliance-aligned dashboards and reporting for frameworks including PCI DSS, GDPR, and ISO standards. Cyberseer offers flexible delivery models including co-managed and fully managed options. The onboarding process includes use-case mapping, log ingestion configuration, rule tuning, and continuous optimization. The service includes management of log ingestion and retention to control costs while maintaining compliance requirements. The UK-based SOC employs analysts with certifications including CISM, CISSP, and SC clearance. Detection capabilities cover behavioral analytics through UEBA, cloud monitoring across AWS, Azure, Google Cloud, and Microsoft 365, and correlation of identity, email, and endpoint data.
