Detection & Mitigation

Every log in one place. Every threat in context.

Cybergen designs, deploys and runs cloud-native SIEM that turns millions of log events into the handful of incidents that matter, with behaviour analytics, automated response and the retention your auditors expect.

Signal and noise

Too much data. Not enough signal.

Security teams drown in logs while the attacks that matter look like routine activity. A well-run SIEM reverses that.

Correlation in action

Four alerts. One attack.

On their own, each event looks minor. Correlated, they tell a clear story. Try it.

Capabilities

Everything a modern SIEM should do for you

raw{ user, ip, action }

Collection and parsing

Connect cloud, on-premises and SaaS sources. Normalise data into a consistent schema so it can be searched and correlated.

Search and threat hunting

Search across recent and historical data in one place, and pivot straight from a result into a detection or dashboard.

Detection engineering

Analytics rules mapped to attacker techniques, tuned to your environment and reviewed as threats change.

Behaviour analytics

Baselines for users and devices highlight anomalies such as unusual access, insider risk and lateral movement.

AlertEnrichAct

Automated response

Playbooks that revoke sessions, isolate devices or open tickets automatically, with approval steps where you want them.

Dashboards and compliance reporting

Executive and operational dashboards, with reports that evidence monitoring for ISO 27001, Cyber Essentials, PCI DSS, NIS2 and DORA.

Retention and cost

Log what matters. Keep what you need.

SIEM costs grow with data volume. We design ingestion and retention so you keep the visibility and the evidence, without paying to analyse noise.

  • Ingest what improves detection, filter what doesn't
  • Route verbose logs to lower-cost tiers
  • Set retention by data type and regulation
  • Review ingestion and cost every month
Analytics tierDetect

Hot, fully searchable data for detection and investigation. Kept for the period your threat detection needs.

Archive tierRetain

Low-cost long-term storage for compliance and forensic look-back, restored when needed.

SIEM FAQ

Your questions, answered

Can't see your question? Ask our team.

What is a SIEM?

Security information and event management collects log and event data from across your estate, correlates it to detect threats, and supports investigation, response and compliance reporting from one place.

Which SIEM platform do you use?

We recommend a cloud-native SIEM that integrates natively with the identity, productivity and cloud platforms you already use. We will advise on the best fit after understanding your environment, licensing and existing tools.

How do you keep SIEM costs under control?

By designing ingestion around detection value, routing verbose data to lower-cost tiers, setting retention by data type and reviewing usage every month.

Do we need people to watch the SIEM?

A SIEM raises alerts that someone needs to act on. You can run it yourselves, co-manage it with us, or have Cybergen's 24x7x365 SOC monitor and respond for you.

Can a SIEM help with compliance?

Yes. Centralised logging, retention and reporting support evidence for frameworks including ISO 27001, PCI DSS, NIS2 and DORA. Compliance also depends on your wider controls and processes.

What is the difference between SIEM and MDR?

A SIEM is the platform that collects and correlates data. MDR is a service where experts monitor, investigate and respond. Many organisations use both, with the SIEM feeding the MDR service.
