Security monitoring that turns logs into answers

SIEM and security monitoring is one layer of our managed cybersecurity and compliance stack, and the one that ties the others together. Every prevention tool sees its own slice: the endpoint agent watches the device, the mail filter watches the mailbox, the identity platform watches sign-ins. Monitoring collects what all of them report into one place, and looks for the pattern that only shows up when you read them side by side.

• One searchable timeline across endpoints, servers, identity and Microsoft 365
• Correlation that connects events no single system could see on its own
• Detection, threat hunting, and the evidence trail an investigation runs on

From raw logs to a detection you can act on

A log is a record that something happened. On its own it is close to useless: one sign-in, one script, one file copy. Even a small office produces far more of them in a month than anyone is ever going to read.

A SIEM (security information and event management platform) is what makes them useful. It collects logs from every source worth watching, normalizes them into a common shape, keeps them searchable, and runs detection rules against them as they arrive. What comes out the other side is not a log. It is a short list of things worth a person's attention, with the surrounding events already attached.

What it catches that nothing else does

Single-point tools are good at what they recognize. What gets past them is usually spread across systems, and quiet. The same account failing sign-ins from three countries in one afternoon. An ordinary administrative script that ran on four machines and was never scheduled. A mailbox rule created at 2am that forwards invoices to an outside address. Each of those looks unremarkable in the system that produced it, and obvious the moment you line them up.

Monitoring is also what closes an investigation. When something does happen, the first question is always scope: which accounts, which machines, what was reached, and when it started. That answer comes out of collected logs, or it does not come at all. How long that evidence is kept, and what an auditor is shown, is the job of the compliance logging layer next door.

When a business actually needs its own SIEM

Not every business does, and running a SIEM badly is worse than not running one. The platform needs log sources wired in, detection rules tuned to your environment, and somebody reading the output on a schedule. Bought and left alone, it becomes an expensive archive.

So we place it where it earns its cost. Day-to-day detection and response lives with the staffed SOC in our managed detection and response layer, which runs on Advanced plans and up, where an alert reaches an analyst instead of a dashboard nobody has open. A full SIEM deployment lands on the Compliance plan, and only where it is genuinely required: when an auditor, a regulator or a cyber-insurance questionnaire asks for centralized log collection, correlation across systems, and evidence that somebody reviews what it finds.

How we deliver it today

Where a client needs one, we build it on the Compliance plan using Microsoft Sentinel (formerly Azure Sentinel), fed by Microsoft Defender for Endpoint telemetry on the clients where that agent is deployed, alongside Microsoft 365 and identity sign-in activity from your own tenant.

Monitoring only pays off next to the layers that feed it and act on it. Endpoint protection and EDR is where most of this telemetry starts, managed detection and response is the human layer that acts on what turns up, and compliance logging is where the same events are retained as audit evidence.

For the part your team actually touches, our knowledge base covers how email threat protection works day to day, including what happens after someone reports a suspicious message, one of the signals that lands in the monitoring queue, and where to look when a legitimate email does not arrive.
