SIEM as a Service
Security Information and Event Management (SIEM) as a Service
Accel Cybersecurity offers Managed SIEM solutions to bolster your organisation’s cyber defences.
What is SIEM as a Service?
Security Information and Event Management (SIEM) as a Service is a cloud-based solution that integrates security services, log management, and monitoring tools. It delivers real-time threat detection and incident response capabilities.
Managed SIEM, also known as SIEMaaS, empowers businesses to swiftly detect network attacks and data breaches.
Benefits of a SIEM Solution
Deploying a SIEM solution offers several advantages:
Data Aggregation
Collects data from diverse sources like network devices, servers, databases, and applications.
Correlation
Analyses events and groups them into meaningful clusters using correlation rules.
Alerting
Automates analysis of correlated events, generating alerts for immediate security issues. These alerts can be displayed on dashboards or sent via email or SMS.
Dashboards
Visualize collected event data using informative charts and graphs. This aids the SIEM team in identifying patterns and anomalies in network activity.
Compliance
Applications can automate compliance data collection, generating reports that align with existing security, governance, and auditing processes.
Retention
Enables long-term storage of historical data for extended data correlation and compliance requirements. This data is also crucial for forensic investigations.
Reduced Data Volume
Processing can be applied at collection agents to ensure only relevant information reaches the central server, minimizing data storage and transmission requirements.
Components & Capabilities
While SIEM systems offer significant benefits, initial deployment costs can be high. However, these costs are typically one-time expenses.
Furthermore, compliance mandates and industry standards, such as PCI-DSS, have driven widespread SIEM adoption across organizations. SIEM also serves as a valuable detective control for identifying Advanced Persistent Threats (APTs) within a network.

Why Choose SIEM as a Service?
Organisations deploying on-premises SIEM solutions often face resource constraints. Managing such systems requires a large team of security specialists for deployment, analysis, and response to the high volume of alerts, including identifying false positives.
Alert fatigue, a common challenge, can lead to overlooking crucial security alerts.
SIEM-as-a-Service bridges this resource gap by providing access to the latest SIEM technology and a team of security professionals for 24/7 management and monitoring. The ability to rapidly detect and identify security events is just one of the many advantages that make SIEM-as-a-Service a vital security resource for businesses and IT departments.
Here’s a closer look at some key benefits:
SIEM-as-a-Service gathers event logs from multiple network devices, empowering security personnel to identify potential issues more readily. This simplifies activity checks, expedites file analysis, and frees up employee time for other tasks. Additionally, SIEM systems can enhance reporting processes and potentially reduce staffing costs.
By aggregating and normalising an organisation’s security data, SIEM-as-a-Service facilitates analysis and utilisation within incident response workflows. The normalised data enables extended analytics and reporting, improving both visibility and compliance.
Managed SIEM solutions collect security event data from across an organisation’s network, mitigating the risk of threat actors remaining undetected. Data analysis aids in the detection and response to network threats as soon as possible.
SIEM-as-a-Service offers a swift response to detected security events, significantly reducing the potential impact of a security breach. Early breach detection or even pre-emptive identification of security events can significantly minimise financial losses, business disruptions, and the overall scale of a security incident.
SIEM-as-a-Service offers in-depth reporting on the security status of the entire network, providing a cohesive overview. This is achieved by collecting and storing logs from various security tools and generating reports that encompass the entire network, rather than individual components.
SIEM-as-a-Service significantly simplifies the process of meeting compliance obligations. It streamlines data collection from all network hosts, eliminating the need for manual compilation. This reduces the time required for compliance activities and eases the process of passing compliance audits. Additionally, many SIEM tools offer built-in functionalities that assist organizations in implementing controls that meet specific standards like ISO 27001.
