What’s included
A SIEM that earns its keep, managed end to end.
Centralised log collection
Logs from across your estate brought into one place: endpoint, cloud, network, identity and more.
Correlation and prioritisation
Events correlated and ranked by real risk, so your team sees the threats that matter, not noise.
24×7 monitoring
Your SIEM watched around the clock, with alerts triaged by analysts before they reach you.
Proactive threat hunting
Active searches for hidden activity, rather than waiting for an alarm to fire.
Compliance-ready retention
Log retention that satisfies audit and regulatory requirements, with recent data kept readily accessible.
Vendor-agnostic integration
Works across the tools you already run. We do not tie you to a single platform.
How it works
- 01
Onboard
We profile your environment, define your assets and agree escalation procedures.
- 02
Implement
Log collection is deployed, your sources connected and the data confirmed as flowing.
- 03
Baseline
A baseline of normal activity is established and the rules tuned to cut false positives.
- 24×7 live
Operate
Continuous monitoring, triaged alerts and regular reviews to keep it sharp.
Operated by a 24×7 managed SOC, with evidence that feeds your continuous compliance, so detection and proof come from one service.
What a SIEM is
One place to collect, correlate and keep your security logs.
A SIEM (security information and event management platform) gathers logs from across your estate, normalises them, correlates related events into alerts, and keeps the record for investigations and audits.
Why managed
Most SIEMs fail through neglect, not design.
Sources quietly stop sending logs, detection rules go stale, and noise buries the alerts that matter. A managed SIEM keeps sources connected and checked, rules tuned to your environment, and alerts triaged around the clock, so the platform keeps doing the job you bought it for.
What to log
The sources that matter most.
- Identity: directory sign-ins, MFA events and admin changes
- Endpoints: detection and response telemetry from laptops and servers
- Email security: blocked, delivered and reported messages
- Cloud and SaaS: audit logs from your cloud platforms and key applications
- Network edge: firewalls, VPN and remote access
- Critical servers and line-of-business applications
Retention and compliance
How long to keep logs depends on who is asking.
Some requirements are explicit: PCI DSS requires at least 12 months of audit log history, with the most recent three months immediately available. Frameworks such as ISO 27001, DORA and NIS2 require logging and monitoring but leave the retention period to your risk assessment and any legal, regulatory or contractual duties, which in some sectors or countries set a minimum.
Set retention from those requirements, then keep recent data quick to search and older data in cheaper storage.
What drives cost
Volume and retention, mostly.
SIEM cost is driven mainly by how much data you send and how long you keep it. Filtering out low-value logs before they are ingested, and tiering older data, usually does more for the bill than changing platform.
FAQ
Questions buyers actually ask
- A SIEM is the platform that collects and correlates logs. A managed SOC is the team and process that watches what the SIEM and other tools surface, investigates it and escalates incidents. A SIEM without people watching it rarely delivers its value.
- Not always. MDR covers threats on endpoints and connected sources well. A SIEM adds correlation across your wider estate and the long-term log retention that audits, regulators and investigations often need. Which you need depends on your compliance obligations and environment.
- PCI DSS sets a 12-month minimum. Most other frameworks leave the period to your risk assessment and any legal, regulatory or contractual duties.
- Mainly data volume and retention. We scope it on a call rather than against a list price.
