SIEM & Threat Detection
Splunk Enterprise Security deployed with a detection library tuned for Saudi banking threats and regulatory evidence requirements.
Crux delivers end-to-end Splunk services for Saudi banks and financial institutions — from architecture and deployment through compliance use-cases, SOC enablement and day-two tuning, aligned with SAMA, NCA ECC and PDPL.
Splunk Enterprise Security deployed with a detection library tuned for Saudi banking threats and regulatory evidence requirements.
Splunk SOAR playbooks that close the loop on high-volume alert types — cutting analyst workload while keeping full case history.
Splunk Observability Cloud for application performance, infrastructure health and real-user monitoring across digital banking channels.
Splunk unifies security, IT operations and application observability on a single search and analytics engine. For a Saudi bank this means threat detections, application SLAs and infrastructure health all draw on the same indexed data — no separate toolchains to correlate by hand.
Enterprise Security is the detection and investigation layer. Crux deploys it with a detection library that maps directly to the threat categories Saudi bank supervisors examine — and produces the evidence artefacts their assessors look for.
Pre-built and custom searches covering account takeover, insider threat, payment fraud, API abuse, lateral movement and privileged account misuse — tuned to your transaction volumes to keep false-positive rates workable.
Risk scores accumulate across a user or system over time. Analysts are paged on a risk threshold crossing, not every individual event — so high-confidence cases surface while noise stays suppressed.
Every alert generates a notable event with a full investigation timeline, asset and identity enrichment, and a documented close-out — producing the audit trail compliance teams need without manual effort.
MISP, Anomali and commercial feeds enriched against every search — IPs, domains, file hashes and TTPs mapped to MITRE ATT&CK for context analysts can act on immediately.
Every device and account in scope is mapped to a risk tier. Splunk's UBA module adds behavioural baselines so deviations are caught even when no specific rule exists.
Glass tables and adaptive response actions let analysts contain a threat from inside Splunk — blocking a user, isolating an endpoint, or submitting a ticket — without switching tools.
Compliance reports on log coverage, mean-time-to-detect, unresolved notables and control effectiveness are generated on a schedule and shared with risk, audit and the CISO automatically.
Every Splunk detection we deploy is mapped to the control it satisfies. The result is a living compliance artefact — not a report assembled before an assessment, but evidence produced continuously by the platform itself.
| Use case | What Splunk detects / produces | Regulation |
|---|---|---|
| Privileged account monitoring | All admin actions logged, alerted on off-hours access and configuration changes, with maker-checker evidence for auditors. | SAMA NCA ECC |
| Payment fraud detection | Anomalous SWIFT and domestic payment patterns flagged in real time with risk scoring and auto-hold workflow. | SAMA SWIFT CSP |
| Failed authentication spikes | Brute-force and credential stuffing detected across all authentication logs; auto-lockout playbook fires on threshold breach. | NCA ECC SAMA |
| Data exfiltration indicators | Bulk data queries, unusual export volumes and off-hours API calls correlated to identify potential PDPL-relevant data movement. | PDPL NCA ECC |
| Configuration and change control | All system changes captured and alerted on; deviations from approved baselines produce a notable with the change diff attached. | NCA ECC SAMA |
| Dormant account activation | Accounts inactive beyond policy threshold flagged on first use; SOC triages before session continues. | SAMA |
| Third-party / API access monitoring | All partner and vendor API calls monitored for rate, scope and data touched — required for open banking environments. | SAMA PDPL |
| Incident response timelines | Automated evidence collection from detection to containment, meeting SAMA's mandatory 72-hour incident reporting timeline. | SAMA |
SOAR automates the first-response steps that currently consume analyst time. Each playbook is authored, version-controlled and approved before production — and every automated action is logged with its trigger and outcome for the audit trail.
On threshold breach: lock the targeted account, submit enrichment to threat intel, open a case with full context, and notify the customer via the bank's notification channel — all within seconds.
Unusual card spend detected: flag the transaction, trigger a real-time authorisation block request, create a case for the fraud team with the merchant, amount and device fingerprint pre-populated.
Anomalous data access correlated with HR signals: capture a full session transcript, escalate to a dedicated queue, and notify the data protection officer for PDPL obligations.
When a mobile banking app slows down or a payment API degrades, the bank needs to know before customers call. Splunk Observability gives engineering teams full-stack visibility — from the customer's browser through the microservice layer to the database query.
CPU, memory, network and storage across on-premise, cloud and hybrid deployments — with dashboards per team and alerts on any deviation from a dynamically set baseline.
Distributed traces across every microservice in the digital banking stack. Latency, error rates and throughput tracked per service, with the specific slow span highlighted automatically.
Session-level data from the customer's browser or mobile app: page load times, API call durations, JavaScript errors and the full sequence leading to a transaction failure.
When a threshold is breached, Splunk can page the on-call engineer via PagerDuty or Opsgenie with full context, reducing the time from alert to investigation from minutes to seconds.
Continuous scripted tests of the mobile app login, transfer and payment flows run from multiple Saudi regions — so degradation is caught before a real customer hits it.
Security and observability data share the same index. When an application anomaly and a security event co-occur, analysts and engineers can see the same event sequence without context-switching.
A SIEM is only as good as the data feeding it. Crux runs a structured onboarding process for every log source — from initial collection planning through field normalisation against the Splunk Common Information Model (CIM) to coverage verification against the control list.
Map every system in scope to a log type, collection method and retention requirement. Produce a coverage matrix against the SAMA and NCA control list before a single log is ingested.
Deploy Splunk Universal Forwarders, syslog receivers or API-based inputs depending on the source. All data in transit is encrypted; credentials are managed in Splunk's credential vault.
Each data source is mapped to a Splunk CIM data model — Authentication, Network Traffic, Endpoint, Change, Transactions. Normalised fields mean every detection works across every source without custom queries.
Log volume is measured at source and compared at index. Gaps and delays are identified and resolved. Expected event-per-second ranges are documented so future anomalies are caught automatically.
After onboarding, each correlation search in the library is run against the new source. Coverage gaps are documented and either filled by a new search or accepted with a risk sign-off.
Every data source is documented: collection method, parser, expected volume, known quirks and escalation path. The SOC team receives a runbook and a training walkthrough before the source goes live.
Deploying the platform is half the work. The other half is ensuring the SOC team can operate it confidently — understand what a notable event means, know how to investigate efficiently, and close cases with the right documentation.
Role-based Splunk training for L1 triage, L2 investigation and L3 threat hunting — delivered in Arabic or English, with exercises built from Saudi banking threat scenarios.
Every correlation search ships with a runbook: what triggered it, the initial triage questions, the investigation steps, the escalation path and the documentation requirements for SAMA incident reports.
Custom dashboards and saved searches for proactive hunting on the data sources the bank has — looking for patterns that do not fire a rule but indicate low-and-slow compromise.
Access is configured by role from day one — L1 analysts see triage queues and enriched notable events; L2 investigators have search access scoped to relevant indexes; L3 threat hunters have broad search permissions; team leads have reporting and performance dashboards; compliance officers see control evidence views. No single account has unnecessary breadth.
Every engagement follows the same four-phase structure. Phases can overlap where timelines require it; each phase ends with a documented sign-off before the next begins.
Architecture review, log source inventory, control mapping, sizing and deployment topology. Deliverable: signed-off design document.
Platform deployment, data onboarding, CIM normalisation and initial detection library. Deliverable: production platform with verified log coverage.
Compliance use-case build-out, SOAR playbook authoring, SOC training and runbook delivery. Deliverable: trained SOC and documented detection library.
False-positive reduction, content updates, health monitoring, capacity reviews and quarterly compliance reporting. Deliverable: retained operational service.
On-premise (bare metal or VM), private cloud on-KSA infrastructure, hybrid, or Splunk Cloud — licensed and operated within Saudi Arabia's data residency requirements.
Crux helps size the daily ingest volume accurately and advise on the licence model — ingestion-based or infrastructure-based — to avoid over-licensing while leaving room for growth.
If you already have Splunk but are not getting value from it, we run a structured health check: data coverage gaps, performance issues, unused content and licensing waste — with a prioritised remediation plan.
For banks that want Crux to operate the monitoring function, we provide a managed detection and response service on top of the deployed platform, with defined SLAs and escalation paths.
Saudi financial institutions operate under SAMA's Cybersecurity Framework and NCA's ECC, both of which require specific control evidence — log retention, alerting on privileged account behaviour, API abuse detection and incident response timelines. Splunk Enterprise Security ships with a content framework built for exactly this kind of evidence production and has the broadest Saudi bank reference base in the region.
A core SIEM deployment covering the primary log sources, an initial detection library and the first SOC dashboards runs eight to twelve weeks. SOAR and observability workstreams can run in parallel. Day-two tuning and content expansion are ongoing; we structure these as a retainer so the platform keeps pace with your threat environment.
Core banking transaction logs, Active Directory / Entra ID authentication events, network firewall and IPS feeds, privileged access management (PAM) sessions, SWIFT messaging, and endpoint detection telemetry. These cover the controls SAMA and NCA assessors most frequently examine and produce the highest-fidelity detections against insider threat, account takeover and payment fraud.
Yes. We maintain a control-to-use-case mapping for NCA ECC and SAMA CSF. Each use case is implemented as a named correlation search in Splunk ES with evidence collection built in, so compliance artefacts are generated continuously rather than assembled manually before each assessment.
Yes. We offer a managed detection and response add-on as well as a lighter health-and-tuning retainer. Both include regular review of detection coverage, false-positive reduction, content updates when Splunk ships new threat content, and capacity planning ahead of licence renewals.
SOAR playbooks handle the repeatable first-response steps automatically — account lockout on confirmed credential stuffing, ticket creation and enrichment from threat intelligence, firewall block requests, and customer notification on card fraud — so analysts work on cases that genuinely need human judgement. Banks typically reduce mean-time-to-respond by 60–80% on high-volume alert types within the first quarter of production.
Whether you are deploying Splunk for the first time, replacing a SIEM that is not delivering, or looking to extend an existing deployment with SOAR and observability — talk to the team that has done it for Saudi banks.
