Everyone agrees that sharing threat intelligence is a good idea. Fewer organisations manage to actually do it. The challenge is not technology; it is trust, governance, legal risk, and the hard work of getting busy people to contribute consistently. A platform alone does not create a community. People do.
When your community is working well, it does not just produce more indicators. It gives every member organisation a clearer picture of who is targeting them, how attacks unfold, and what to prioritise. We know what that looks like in practice.
Newer members consume intelligence through reports, email advisories, and curated briefings. They are building awareness and internal processes before they automate.
Members at this level pull structured indicators from a portal or feed — IOC lists, CSV exports, or SFTP downloads — and use them in their own detection and response workflows.
More mature members connect directly to the community MISP instance via API or STIX/TAXII, ingesting intelligence into their own TIP, SIEM, or SOAR for automated detection and enrichment.
The most mature members contribute their own intelligence to the community. They run bidirectional syncs, share sightings, and help curate and contextualise intelligence for others.
Every community we build is designed to support members across the full maturity spectrum.
Start a successful communityCosive co-designed and developed Australia’s national Cyber Threat Intelligence Sharing (CTIS) platform: a bi-directional sharing hub bringing together government agencies, critical infrastructure organisations and the private sector for real-time threat sharing.
CTIS leverages MISP and the STIX/TAXII standards so members can connect with the tools they already run, whether that's a threat intelligence platform, a SIEM, or a SOAR. No one has to adopt a brand new stack to take part, which is what makes joining realistic for a busy team.
Building the platform was never the hardest part. What made CTIS work was a focus on the human factors most communities underestimate: agreeing what gets shared and with whom, getting legal and compliance teams comfortable, and setting clear TLP and confidentiality rules. This framework created the necessary conditions for trust between organisations that wouldn't otherwise work together.
A fully managed MISP instance deployed in your preferred AWS region, with enterprise-grade reliability and support.
Consulting to help you design the rules, processes, and culture that turn a platform into a functioning community.
Custom integrations that connect member security tools to the community, plus ongoing support to keep everything running.
Real results from real engagements across threat intelligence sharing, national programmes, and community operations.
Designed the governance framework, deployed the platform, and operated a national-scale sharing programme connecting government agencies with critical infrastructure operators across energy, transport, finance, and telecommunications.
Worked with a major UK rail operator to establish structured threat intelligence sharing with industry peers, creating new integrations that connected their internal security tools to a sector-wide community platform.
Helped a consortium of banks across the Asia-Pacific region build a cross-border threat intelligence sharing community — from governance design and legal frameworks through to CloudMISP deployment and analyst onboarding for member organisations.
