Our Splunk Specializations
Three Capabilities. One Unified Analytics Hub.
From setting up initial system data models to coding multi-app workflow integrationsSourceMash engineers scalable pipelines to accelerate security response windows across your modern global infrastructure.
Practice 01
Log Analytics Architecture & Edge Data Ingestion
Data velocity can strain operations and inflate licensing footprints. SourceMash designs scalable data topologies using Splunk Universal Forwarders and Heavy Forwarders to safely gather data from any operating system, cloud layer, or physical host. We focus on normalizing raw text structures via the Splunk Common Information Model (CIM), filtering non-essential events at the network perimeter to lower retention storage investments while maintaining rich trace accessibility.
Data Parsing & Index Sizing Optimization
Configuring custom transforms.d and props.conf files to strip out redundant data structures like verbose web traffic headers at the log boundary before it reaches storage clusters, lowering infrastructure indexing overhead significantly.
Multi-Cloud Log Ingestion
Securing visibility across public cloud setups. We engineer reliable data integrations using event firehoses, webhooks, and storage queues to systematically collect operational logs from AWS CloudTrail, Azure Log Analytics, and GCP Pub/Sub streams.
Indexer Clustering & Storage Tiering
Architecting robust data availability models. We configure multi-site indexer clusters using high-speed flash arrays for hot search paths, automatically moving older trace libraries down to cold cloud-object pools to satisfy multi-year data retention compliance guidelines.
Log Infrastructure Core Capabilities
Practice 02
Splunk Enterprise Security Threat Intelligence
Isolated indicators are easy to miss. SourceMash deploys and optimizes Splunk Enterprise Security (ES) to correlate alerts from distinct systems across your enterprise environment. By building behavioral tracking models and custom risk scores, we map active alert groups to the universal MITRE ATT&CK framework, turning raw text streams into prioritized security alerts.
Correlation Rule Architecture
Engineering security rules inside Splunk. We build custom correlation searches that analyze disparate activitieslike unusual database access combined with sudden outbound connectionsto flag advanced threats while ignoring benign corporate activity.
Risk-Based Alerting (RBA) Deployment
Transitioning operations away from static alert models. We replace traditional system alerts with a modern Risk-Based Alerting setup, tracking threats across individual users or assets over time to surface high-risk patterns cleanly.
Threat Intelligence Feed Automation
Integrating intelligence sources seamlessly. We link real-time threat data directly into your Splunk environment via TAXII, STIX, or custom cloud APIs, cross-referencing outbound network traffic against known malicious hosting vectors automatically.
Enterprise Security SIEM Core Capabilities
Practice 03
Splunk SOAR Engineering & Playbook Orchestration
Manual threat containment is too slow to stop modern attacks. SourceMash builds automated workflows using Splunk SOAR (formerly Phantom) to orchestrate defensive actions across your entire tech stack at machine speed. We integrate third-party APIs directly, building reliable visual and Python-based playbooks that automatically block active attacks within seconds.
Python & Visual Playbook Engineering
Building reliable response automation workflows. We write custom Python structures inside Splunk SOAR to manage alert tasks like parsing attachments, querying file reputations, and managing multi-step approval gates safely.
App Asset API Integration
Linking disparate security products. We deploy and configure verified connection assets to orchestrate actions directly across Active Directory, Microsoft Exchange, CrowdStrike nodes, and Cisco firewalls safely.
Automated Phishing Containment
Streamlining inbox security. We build playbooks that extract URLs and attachments from reported emails automatically, checking reputations through sandboxes and deleting identical malicious variants across all enterprise mailboxes within seconds.
Transforming Incident Timelines: From Hours to Machine-Speed Seconds.
Manual triage often causes critical delays during active attacks. When a compromised credential triggers an alert, standard remediation paths rely on waiting for on-call engineers to log in, review the trace context, and disable access manually. SourceMash engineers Splunk SOAR playbooks to handle these verification sequences automaticallyquerying asset locations, validating abnormal patterns, and disabling compromised accounts via API commands within seconds of discovery.
SOAR Operational Core Capabilities
Our Splunk Engineering & Delivery Lifecycle
A carefully planned, phased engineering approach to onboard critical data sources and build robust automation playbooks safely.
Infrastructure Audit & License Sizing
We analyze your target infrastructure layout and daily log generation models, evaluating structural performance across active data patterns to map out index storage retention buckets and plan license size strategies accurately.
Forwarder Architecture & Secure Ingestion
We deploy lightweight Splunk Universal Forwarders across your assets, configuring secure TLS connections and setting up Heavy Forwarder tier parsing rules to normalize raw machine data before it moves to core indexers.
CIM Normalization & Data Alignment
We map all incoming log streams to the standard Splunk Common Information Model (CIM), aligning variable event fields across cloud networks, identity layers, and endpoints to enable reliable enterprise searches.
SIEM Correlation Rule Customization
We configure tailored correlation rules within Splunk Enterprise Security, tuning baseline behavior models, updating risk-scoring matrices, and linking event patterns directly to MITRE ATT&CK identifiers.
SOAR API Integration & Playbook Engineering
We configure API connections across your infrastructure stack inside Splunk SOAR, building visual and Python-based automation playbooks to manage threat containment loops like active network isolation securely.
Continuous Management & Query Acceleration
Transition to steady-state operations. We monitor cluster health continuously, optimize slow-running SPL queries using summary indexing, upgrade application packs safely, and run regular threat simulations to ensure maximum reliability.
