Should Malaysian SMEs deploy a cloud-based or on-premises SIEM?

For most Malaysian SMEs, a cloud-based SIEM is the more practical choice — it eliminates the need for dedicated hardware, reduces upfront capital expenditure, and scales with log volume. On-premises SIEM remains relevant for organisations with strict data residency requirements or highly classified environments. Simply Data helps clients evaluate both models against their regulatory obligations and budget before recommending an architecture.

How long must Malaysian organisations retain SIEM logs under RMiT and PDPA?

Bank Negara Malaysia RMiT requires financial institutions to retain security event logs for a minimum of three years, with critical audit trails accessible for at least one year online. Under PDPA, log data containing personal information must be protected and not held longer than necessary — meaning retention policies must balance compliance and data minimisation. Simply Data configures log retention tiers in your SIEM to satisfy both RMiT and PDPA obligations simultaneously.

What does a managed SIEM service cost for a Malaysian SME?

Managed SIEM pricing in Malaysia typically depends on daily log ingestion volume, the number of monitored data sources, and whether 24/7 SOC analyst coverage is included. Compared to building an in-house SIEM — which requires licensed software, hardware, and at minimum two trained analysts — a managed service from a NACSA-licensed provider like Simply Data is almost always lower in total cost of ownership. Contact Simply Data for a quote tailored to your log volume and compliance scope.

What is the difference between managed SIEM and running SIEM in-house?

An in-house SIEM requires your team to handle rule tuning, threat feed updates, false-positive triage, and 24/7 alerting — a significant operational burden for most Malaysian SMEs that lack a dedicated security operations team. A managed SIEM service transfers that operational responsibility to a specialist provider, with SLA-backed response times and continuous expert oversight. Simply Data operates a NACSA-licensed Cyber Security Service Provider (CSSP) SOC that monitors client SIEM deployments around the clock.

How does Simply Data SOC use SIEM for 24/7 threat monitoring?

Simply Data SOC ingests client log sources — endpoints, firewalls, cloud workloads, and identity platforms — into a centralised SIEM, applying continuously updated detection rules and threat intelligence feeds to surface high-fidelity alerts. Analyst teams triage every alert in real time, suppress false positives, and escalate confirmed incidents with context-rich reports and recommended containment steps. Simply Data holds NACSA CSSP Licence 20007-01 (SOC) and is a CREST member (ID 6960553-2), providing an internationally recognised standard of SOC operations.
