Broad log collection
Ingestion from network, identity, endpoint, email, and cloud sources — visibility is only as wide as the inputs.
Layered Defence — Layer 6 of 7
The Monitoring Layer
Seeing what is happening across every layer, all the time.
Every layer of defence produces signals — login attempts, blocked connections, endpoint alerts, email verdicts. Individually they look like noise. The Monitoring layer brings them together, because attacks rarely trip one alarm loudly; they trip several quietly, across different systems.
This layer is what turns a collection of controls into a defence that can actually be operated: one place where the organization sees what is happening, investigates what matters, and keeps the records that compliance and insurance increasingly require.
SIEM
Security Information and Event Management collects, analyzes, and correlates security data from across an organization to detect, respond to, and mitigate threats in real time.
Every layer of defence produces logs — the firewall, the identity platform, the endpoints, the email gateway, the cloud services. Individually, a failed login or an odd network connection looks like noise. A SIEM brings those streams together and correlates them, revealing the pattern: the failed logins, then the successful one from a new country, then the unusual data transfer — a sequence no single tool would flag on its own.
Beyond detection, the SIEM is the investigation workbench. When an alert fires, analysts pivot through the correlated history to establish what happened, when it started, and what was touched. Retained logs also serve compliance: many frameworks and cyber-insurance policies expect centralized logging with defined retention.
A SIEM is only as good as its tuning. Connecting the right sources, writing correlation rules that reflect real attack paths, and suppressing the noise are what separate a system that catches intrusions from one that generates a thousand ignored alerts a day — which is why the operational discipline around a SIEM matters as much as the platform itself.
What to look for
Correlation rules
Logic that connects individually-innocuous events across systems into a detection of the actual attack.
Investigation tooling
Fast search and pivoting across retained data, turning an alert into a timeline.
Defined retention
Log retention that satisfies the compliance frameworks and insurance requirements that apply to you.
Tunable signal-to-noise
The ability to suppress and refine alerts, so real intrusions are not buried under false positives.
Part of a Layered Defence
No single technology can protect against every threat. The Monitoring layer works alongside six other security layers, each creating another barrier an attacker has to defeat — and another opportunity to detect them.
- 1. Human
- 2. Devices
- 3. Network
- 4. Identity
- 5. Data
- 6. Monitoring
- 7. Response
