What is Sophos Next-Gen SIEM?
Sophos Next-Gen SIEM is a compliance-focused add-on for Sophos XDR Powered by Secureworks and Sophos MDR. It extends the same system you use for threat detection and response with long-term data retention, expanded data ingestion and audit-ready compliance reporting, without deploying a separate SIEM platform.
It includes 13 months of data retention as standard, extendable to 3, 5, 7 or 10 years. AI-assisted parsers bring in data from legacy systems, regional tools and internal applications, and built-in dashboards, such as ISO 27001, show auditors and security leaders how consistently your controls are operating.
Unlike traditional SIEMs, Sophos Next-Gen SIEM is priced per user and server, with no ingestion-based fees. It cannot be bought on its own: it extends an existing Sophos XDR or Sophos MDR subscription, and the number of licences matches the users and servers you already cover.
Sophos Next-Gen SIEM is part of Sophos Fusion, the Sophos AI-Native Cybersecurity Defense System. Because it uses the same unified context lake, years of retained data also enrich investigations in Sophos XDR and Sophos MDR.

How CyberLab Delivers Sophos Next-Gen SIEM
The value of a SIEM depends on the data you put in it. We make sure the right sources are connected and retained for the right length of time.
Supporting UK Compliance Requirements
Most UK security frameworks expect you to collect, retain and review logs, and to prove it. Sophos Next-Gen SIEM gives you the retention, reporting and evidence to support that, alongside expert guidance from CyberLab.
Sophos Next-Gen SIEM supports your compliance programme but does not certify you against a framework on its own. Our consultants can help you close the gaps.
Sophos Next-Gen SIEM vs a Traditional SIEM
Traditional SIEMs were built for log storage. Sophos Next-Gen SIEM is built for security and compliance outcomes.

How Much Does Sophos Next-Gen SIEM Cost?
Sophos Next-Gen SIEM is priced per user and server, so your cost is predictable however much data you send it. The number of licences matches the users and servers already covered by your Sophos XDR or Sophos MDR subscription. The main variable is how long you need to keep data: 13 months is included as standard, and longer retention of 3, 5, 7 or 10 years is an optional add-on. We will help you match your retention period to your actual regulatory needs, so you do not over-buy. Speak with our team for a tailored quote.

FAQs:
Security information and event management (SIEM) collects, stores and analyses logs from across your IT estate, so you can investigate incidents and prove to auditors that security controls are working. A next-gen SIEM adds automation, AI and integration with detection and response tools, rather than acting only as a log store.
Sophos Next-Gen SIEM is a compliance-focused add-on for Sophos XDR and Sophos MDR. It adds long-term data retention of up to 10 years, AI-assisted ingestion of custom data sources and built-in compliance dashboards, all within Sophos Fusion and priced per user and server.

Sophos Next-Gen SIEM includes 13 months of data retention as standard. You can extend this to 3, 5, 7 or 10 years to meet regulatory and audit requirements. Retention covers both threat-related and compliance-focused data.

Sophos Next-Gen SIEM helps organisations meet the logging, retention and reporting requirements of frameworks including ISO 27001, PCI DSS, UK GDPR and SOC 2. For UK public sector and NHS organisations, it supports evidence for the NCSC Cyber Assessment Framework and the Data Security and Protection Toolkit. It supports your compliance programme but does not certify you on its own.

XDR is built for real-time detection, investigation and response. SIEM is built for collecting and retaining logs for investigations and compliance. With Sophos, Next-Gen SIEM extends Sophos XDR, so you get both in one system.
Yes. With Sophos MDR, years of retained security and compliance data give Sophos analysts more context to validate, contain and respond to threats, for example checking whether an attacker or account has been seen before.
