Why managed SIEM

A SIEM only helps if someone runs it

A security information and event management platform collects logs, correlates events and raises alerts. Buying one is the easy part. Keeping log sources connected, writing and tuning correlation rules, managing storage and reviewing alerts every hour of the day is where most internal SIEM projects stall.

With SIEM as a service, Triden takes on that work. We onboard your log sources, keep them healthy, tune detections to your environment and have analysts review what the platform surfaces. When a correlated alert points to a real threat, we investigate and respond as part of our 24/7 MDR service.

For credit unions, healthcare organizations and public agencies, the logs themselves are often a requirement. We set retention and reporting so you can answer an auditor’s question without a scramble.

What’s included

Managed log monitoring from collection to response

Log source onboarding

We connect servers, firewalls, network devices, identity providers, cloud platforms and Microsoft 365, and monitor that each source keeps reporting.

Correlation and detection

Rules that link related events across systems, such as a risky sign-in followed by unusual file access, tuned to cut noise.

24/7 alert review

Analysts review correlated alerts around the clock, investigate what looks real and escalate or contain through agreed runbooks.

Log retention

Storage and retention periods set to your frameworks, contracts and internal policy, with searchable history for investigations.

Compliance reporting

Reports and evidence for log review, access monitoring and incident handling controls in the frameworks you follow.

Managed Microsoft Sentinel and cloud logs

For Microsoft-centric environments, our team supports Microsoft security services, including Sentinel, alongside AWS and Azure cloud logs.

How it works

Standing up managed SIEM

1

Define requirements

We review your frameworks, contracts and investigation needs to decide which logs matter and how long to keep them.

2

Onboard log sources

We connect sources in priority order, starting with identity, firewalls and critical servers, and confirm data quality.

3

Tune and monitor

Detections are tuned to your environment, then analysts begin 24/7 review of correlated alerts.

4

Report and review

You get regular reports for leadership and auditors, plus reviews that adjust coverage as your systems change.

FAQ

Managed SIEM questions

Managed SIEM services are an outsourced way to run a security information and event management platform. The provider onboards log sources, tunes correlation rules, manages retention and has analysts review alerts. You get the detection and record keeping of a SIEM without staffing it yourself.

It depends on the framework. PCI DSS sets a specific rule of at least 12 months of audit logs, with the most recent three months immediately available. HIPAA, CMMC, NIST and NCUA guidance require audit logging and review but leave much of the retention period to your policy, contracts and regulators. We help you set a retention period you can defend, then configure the SIEM to match.

A SIEM is a platform that collects and correlates logs. MDR is a service in which analysts monitor, investigate and contain threats using tools such as a SIEM and endpoint detection. Our managed SIEM feeds our MDR and SOC services, so log alerts lead to investigation and response.

Our team supports Microsoft security services, including Sentinel. We can onboard sources, tune analytics rules, manage retention and review alerts in your existing workspace.

The main drivers are the number and type of log sources, daily log volume, how long you retain data and the level of 24/7 review and response you want. We estimate volume during scoping and give you a fixed monthly price.

Start with identity and sign-in logs, firewall and VPN logs, email and Microsoft 365 activity, and your most critical servers. Those sources catch most of the early signs of an attack and answer most audit questions.
