Managed SIEM
Managed SIEM for clear, actionable threat detection
A managed SIEM turns scattered logs from your firewalls, servers and applications into one clear picture of your security posture, without you needing to read a single log file yourself.
Book Your Free Security Gap CheckSecurity Information and Event Management (SIEM) is the engine behind good threat detection. It collects data from every corner of your IT environment, firewalls, servers, applications and more, and correlates it to spot the patterns a single log entry would never reveal on its own.
DJC's managed SIEM service takes care of the collection, correlation and analysis for you. We tune it to your environment so alerts are relevant and actionable, rather than a flood of noise that gets ignored. That feed is what makes our managed SOC and detection and response service effective in the first place.
A SIEM on its own is just data. What matters is what happens when it flags something, which is why we run it as part of a coordinated cyber security program rather than a standalone tool nobody watches.
What our managed SIEM service covers
Centralised log collection
Ingesting data from firewalls, servers, applications and endpoints into a single, correlated view of your environment.
Anomaly and correlation analysis
Identifying potential threats by connecting seemingly unrelated events across your infrastructure, not just flagging isolated alerts.
Real-time visibility
Giving you and our security team live insight into your security posture, so incidents are caught early rather than discovered after the fact.
Customised alerting
Alert thresholds tuned to your business, so the team only sees notifications that genuinely require action.
If IT is your responsibility
An owner, not an account manager
You deal with Daniel or Julian Church directly. We keep the client list deliberately short so the people who answer already know your environment.
Numbers you can defend
Every engagement starts with a costed IT roadmap: what technology should cost this year and next, in business terms you can take to a board or a budget meeting.

If you already have an IT manager or a small team, we are not here to replace them. Co-managed IT adds tooling, escalation and after-hours cover around them.
How co-managed IT worksWhy DJC
- SIEM feeds our SOC, not a separate silo. The data our managed SIEM collects flows directly into DJC's co-managed SOC, so detection and response work from the same picture.
- Tuned, not just turned on. We configure correlation rules and alert thresholds around your actual environment, avoiding the alert fatigue that makes many SIEM deployments useless within months.
- Backed by an SMB1001 Diamond and ISO 27001 certified team. DJC holds SMB1001 Diamond, ISO 27001 and ISO 9001 certification, reflecting the discipline behind how we manage security data and infrastructure.
Quick answers
What is a managed SIEM service?
A managed SIEM (Security Information and Event Management) service collects and analyses security data from across your IT environment, such as firewalls, servers and applications, to detect threats in real time. DJC manages the collection, tuning and analysis so your team receives clear, actionable alerts instead of raw logs.
Do we need a SIEM if we already have a managed SOC?
A SIEM is the data engine that a SOC relies on to detect threats. DJC's managed SIEM feeds directly into our managed SOC, so the two work together rather than being separate purchases.
How does DJC avoid SIEM alert fatigue?
DJC tunes correlation rules and alert thresholds to each client's specific environment, so alerts reflect genuine risk rather than routine activity. This is reviewed on an ongoing basis as your environment changes.
What systems can a managed SIEM monitor?
DJC's managed SIEM can ingest data from firewalls, servers, cloud platforms, applications and endpoints, giving a single correlated view across on-premises and cloud environments.
