Q: Can OpenCTI automatically push indicators to our defensive tools?

Yes — OpenCTI connectors and API enable automated distribution of indicators to firewalls, SIEM platforms, endpoint protection tools and DNS security services. We build automated pipelines that push curated, validated indicators from OpenCTI to your defensive infrastructure, ensuring new threat intelligence translates into active protection without manual intervention or delay.

We can help you automate your business with OpenCTI and hundreds of other systems to improve efficiency and productivity. Get in touch if you’d like to discuss implementing OpenCTI.

About OpenCTI

OpenCTI is an open-source threat intelligence platform designed to help organisations collect, store, analyse and share cyber threat intelligence in a structured, actionable format. Built on the STIX 2.1 standard and maintained by Filigran, the platform provides a knowledge graph approach to threat intelligence that maps relationships between threat actors, malware families, attack techniques, indicators of compromise and targeted sectors — giving security teams contextual understanding rather than disconnected indicator lists.

For Australian organisations building threat intelligence capabilities, OpenCTI provides a practical foundation without the licensing costs of commercial platforms. The platform ingests intelligence from multiple sources including MISP feeds, TAXII servers, RSS feeds, CSV imports and direct API submissions, normalising everything into a consistent STIX format that enables meaningful correlation and analysis. This multi-source approach lets security teams combine commercial threat feeds, industry sharing groups and internal incident data into a unified intelligence picture.

Where OpenCTI becomes particularly valuable is in operationalising threat intelligence — turning curated intelligence into defensive actions. Through its connectors and API, OpenCTI can push indicators to firewalls, SIEM correlation rules, endpoint detection platforms and automated blocking systems. Our consulting team helps organisations build these automated intelligence pipelines so threat data moves from analysis to protection without manual copy-paste operations that introduce delays and errors.

The platform includes role-based access control, marking definitions for intelligence classification, and workflow capabilities for managing the intelligence lifecycle from ingestion through analysis to dissemination — essential features for organisations that share intelligence with partners, industry groups or government agencies like the Australian Cyber Security Centre (ACSC).

OpenCTI FAQs

Frequently Asked Questions

Common questions about how OpenCTI consultants can help with integration and implementation

How does OpenCTI differ from a SIEM platform?

A SIEM processes your internal security event logs to detect threats in real time, while OpenCTI manages external threat intelligence — knowledge about threat actors, their techniques, malware tools and indicators of compromise. The two platforms are complementary: OpenCTI curates the intelligence that informs your SIEM correlation rules, and SIEM detections can feed back into OpenCTI as internal intelligence. We typically integrate both platforms to create a closed-loop security operations workflow.

What threat intelligence sources can OpenCTI ingest?

OpenCTI supports ingestion from TAXII servers, MISP instances, RSS/Atom feeds, CSV files, STIX bundles and direct API submissions. Pre-built connectors exist for popular intelligence sources including AlienVault OTX, MITRE ATT&CK, abuse.ch, VirusTotal and commercial threat feeds. We configure the connector stack based on your threat landscape and the intelligence sources most relevant to your industry and geography.

Can OpenCTI automatically push indicators to our defensive tools?

How does OpenCTI use the knowledge graph approach to threat intelligence?

OpenCTI models threat intelligence as a graph of interconnected entities — threat actors linked to malware, malware linked to attack techniques, techniques linked to indicators, indicators linked to targeted sectors. This relationship mapping lets analysts trace connections between apparently unrelated indicators, understand threat actor capabilities and assess whether specific campaigns are relevant to their organisation.

Is OpenCTI suitable for organisations with small security teams?

OpenCTI is well-suited to lean teams because it automates the collection and normalisation work that would otherwise consume analyst time. With properly configured connectors, intelligence arrives pre-structured and ready for analysis. The key is having the initial deployment configured correctly and automated pipelines built to operationalise intelligence. We handle that setup so your team can focus on analysis rather than platform maintenance.

Can AI enhance threat intelligence analysis within OpenCTI?

AI models can process the volume of intelligence flowing through OpenCTI to identify patterns, classify emerging threats, predict campaign evolution and prioritise indicators based on relevance to your specific environment. Our AI development team builds classification and enrichment systems that augment OpenCTI with machine learning capabilities, helping analysts focus on the intelligence that matters most.

How it works

We work hand-in-hand with you to implement OpenCTI

As OpenCTI consultants we work with you hand in hand build more efficient and effective operations. Here’s how we will work with you to automate your business and integrate OpenCTI with integrate and automate 800+ tools.

Step 1

Threat Intelligence Requirements Analysis

We assess your current threat intelligence practices, security tool landscape and intelligence consumption needs. This analysis identifies which intelligence sources are relevant to your threat profile, what defensive tools need indicator feeds and how intelligence should flow through your security operations.

Step 2

Platform Architecture Design

Based on your requirements, we design the OpenCTI deployment architecture including infrastructure sizing, connector selection, integration points with defensive tools and access control policies. The architecture accounts for your intelligence volume, retention requirements and any intelligence sharing obligations with partners or industry groups.

Step 3

OpenCTI Deployment and Configuration

We deploy the OpenCTI platform on your preferred infrastructure — on-premises Docker or Kubernetes, or cloud-hosted. Configuration includes user accounts, role-based access controls, marking definitions for intelligence classification and the organisational taxonomy that structures your threat knowledge base.

Step 4

Connector Setup and Intelligence Ingestion

We configure and activate the intelligence connectors for your selected sources — open-source feeds, commercial providers, industry sharing groups and internal data sources. Each connector is tuned for ingestion frequency, confidence scoring and automatic enrichment to ensure intelligence quality from the start.

Step 5

Defensive Tool Integration

Our team builds the automated pipelines that push curated indicators from OpenCTI to your defensive infrastructure — SIEM correlation rules, firewall blocking lists, endpoint detection rules and DNS security policies. These integrations close the gap between intelligence analysis and active protection.

Step 6

Analyst Training and Handover

Your security team receives training on OpenCTI daily operations including intelligence analysis workflows, entity relationship exploration, indicator management and report generation. Documentation covers the deployment architecture, connector configuration, integration pipelines and procedures for adding new intelligence sources as your program matures.
