Threat intelligence sharing sounds simple. The reality is anything but.

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.

We have done this before. Let us help you do it right.

A well-run threat intelligence community changes how your members defend

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. Here is what that looks like in practice.

  • A defined mission — The community knows exactly what intelligence it produces, what is in scope, and what is not. Members are not trying to boil the ocean — they are focused on the threats that matter to their sector or region.
  • Members who trust each other — Vetting is rigorous, expectations are explicit, and every participant has confidence in who they are sharing with. Trust is built through contribution, not just agreements.
  • Intelligence that informs decisions — What members receive goes beyond raw indicators. It includes context: who is behind the activity, what their objectives are, and what actions members should take. Analysts interpret and enrich intelligence before it reaches the community.
  • Governance that people actually follow — Sharing agreements, TLP handling rules, and escalation procedures are documented and practical. Legal and compliance teams have signed off, not just been informed.
  • Operations that do not depend on one person — The community has a clear operating model, dedicated funding, and a team responsible for platform management, member support, and quality assurance.
  • Active participation, not passive consumption — Members attend meetings, share intelligence back to the community, mentor newer participants, and champion the programme within their own organisations.

Meet every member where they are on the maturity journey

1
Reading and learning
Newer members consume intelligence through reports, email advisories, and curated briefings. They are building awareness and internal processes before they automate.
2
Structured consumption
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.
3
Automated integration
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.
4
Producing and sharing back
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.

Where are you on this journey? We use the CTI-CMM Framework to measure maturity and identify your next steps. Learn more here.

Every community we build is designed to support members across the full maturity spectrum.

We work with every type of organisation that shares threat intelligence

GOVERNMENT
National Cyber Security Centres
National cyber security agencies building or scaling programmes that distribute threat intelligence to government networks, critical infrastructure operators, and the private sector.
ISACISAO
Sector ISACs & Trust Groups
Industry-led sharing communities that are formalising how their members exchange threat intelligence — moving beyond email alerts and ad hoc calls to structured, automated sharing with accountability.
ENTERPRISE
Enterprise threat intelligence teams
Organisations with established threat intelligence capabilities that want to share what they learn with trusted peers and contribute to collective defence beyond their own perimeter.
CRITICAL INFRASTRUCTURE
Critical Infrastructure Sharing
Energy, transport, water, and telecommunications operators coordinating threat intelligence across their sector to defend against adversaries who target shared supply chains and interdependencies.
REGIONAL
Regional Sharing Communities
Cross-sector and cross-border communities that bring together organisations within a geographic region to share intelligence on threat actors, campaigns, and tactics relevant to their part of the world.

Questions about building a threat intelligence sharing community

How do you help us get started with a new sharing community?

We work with you from the very beginning. That means defining the community’s purpose and scope, identifying the right founding members, designing governance and legal frameworks, choosing a platform, and planning how you will onboard members and keep them engaged. Whether you are a national cyber security centre, an ISAC, or an enterprise team wanting to share with peers, we tailor the approach to your context and constraints. We have done this at national scale and for smaller, sector-specific groups.

Our community already exists but sharing is still mostly manual. How do you help us automate?

Many communities start with email, spreadsheets, and PDF reports. That is a perfectly valid starting point. When you are ready to automate, we help you deploy a platform like CloudMISP, configure MISP or STIX/TAXII integrations for each member, and build ingestion and dissemination pipelines. The key is meeting each member at their maturity level. Some will connect via API on day one; others will need a simpler path. We take an incremental approach so no member gets left behind.

How do you handle the legal challenges around sharing threat intelligence?

Legal concerns are consistently the biggest barrier to getting a sharing community off the ground. We help you draft data-handling agreements, define TLP and classification rules, and design sharing workflows that give legal and compliance teams confidence that sensitive information stays within agreed boundaries. We have navigated these conversations with government agencies, regulators, and enterprise legal teams across multiple jurisdictions. In our experience, the goal is not to eliminate risk — it is to make the risk well-understood and manageable.

Which platforms and standards do you support?

We support MISP (including our own CloudMISP managed platform), STIX/TAXII-based exchanges, and custom API integrations. Many communities use a combination — MISP as the core sharing platform with STIX/TAXII endpoints for members who need them. We create the new integrations that connect these to members’ internal tools, whether that is a TIP, a SIEM, a SOAR platform, or something else entirely.

Can you also help me consume cyber threat intelligence from external sources?

Yes. The same platform and expertise we use for community sharing also supports individual organisations that want to consume threat intelligence from external feeds, open-source intelligence, and commercial providers. Learn more about consuming and sharing threat intelligence.

Where can I find good threat intelligence feeds to bring into my programme?

We maintain a curated list of open-source and commercial threat intelligence feeds, and we can help you evaluate which ones are most relevant to the threats your organisation actually faces. We also help you integrate those feeds into your security tools so your analysts can act on the intelligence rather than just collecting it. Learn more about threat intelligence feeds.
