MISP vs TheHive

The documented TheHive MISP integration works in three directions, and only some of them are automatic. TheHive imports MISP taxonomies by default, so analysts see the same tag vocabulary in both platforms. It can connect to one or more MISP servers and turn MISP events into TheHive alerts, which then wait in the alert queue for an analyst to review. In the other direction, TheHive can export a case to MISP as an event so that IOCs from an investigation reach the sharing community. Each direction depends on how the connection is configured, so the team should map which MISP servers are connected, which events flow in, and which case data may leave TheHive before anything goes live.

Teams pair the two platforms because they hold different parts of the workflow. MISP keeps the shared indicator context: the event, its attributes, its distribution level and sharing group, and the rules that decide which partners receive it. TheHive gives analysts a place to triage alerts, assign work, record observables and run analysis, with Cortex supplying analyzers and responders alongside it. Used together, an indicator set in MISP can become an alert in TheHive, and a confirmed finding in a case can return to MISP as a shareable event. The pairing works best when the security operations lead can explain which platform is the sharing record and which is the working record.

The integration does not decide the important operating questions. It does not choose which MISP events are worth an alert, how alerts are prioritized or closed, or whether a given case should be shared at all. Those rules sit with the team, and they carry the sharing risk: an IOC exported from a case can leave the organization under the distribution level the team sets. Before deployment, confirm the exact connection, filtering and export settings in the TheHive MISP integration documentation for your version, and document who approves exports to MISP. Record that owner in the runbook, because the integration itself will not record it.

The MISP software itself carries no license fee, because MISP is licensed under AGPL-3.0, so the running cost sits in the people and infrastructure around it. Your team or your implementation partner pays for the hosting, the MySQL or MariaDB database, the Redis instance, and the time to keep synchronization with partner instances working. Recurring work includes managing sync rules and distribution levels as trusted communities change, reviewing taxonomy and galaxy updates, and watching feed health. Upgrades are the largest recurring item. MISP 2.5 is the recommended line and the project has moved its database to a new migration system with PostgreSQL support, so plan a regular upgrade window and a test instance. Ask any partner to price these as separate line items: initial build, recurring upgrades, and on-call coverage for sharing outages.

TheHive is different because its cost is largely per-user licensing above the Community tier. TheHive 5 on-premises Community is free for 2 users, while Gold and Platinum are priced per user, and the price of any plan must be obtained from StrangeBee, since it is not stated in the supplied material. The platform stack adds recurring cost regardless of license: TheHive, Apache Cassandra and Elasticsearch each run on the JVM with their own heap settings, and StrangeBee recommends 100 GB of storage for most use cases. Storage, heap sizing and node count drive hosting cost up as case volume grows. Cortex needs no license, but it still runs infrastructure of its own. The staff needed to run three stateful services is the cost most teams underestimate.

Separate one-time costs from recurring ones before you compare totals. One-time work includes the initial build, the MISP-to-TheHive alert integration, taxonomy import, and any migration of existing cases or events. Recurring costs include licenses, hosting, storage growth, upgrades across both products, and on-call rotation. For a written quote, ask both vendors and partners for: the hosting assumptions and storage sizing; the named upgrade and patch approach; the support and on-call hours covered; the number of users and license tier for TheHive; and the handover documentation. Ask StrangeBee directly for current TheHive plan pricing, and confirm with the MISP community or your partner which support options fit your sharing obligations.

Implementing MISP 2.5 starts with a choice of install path. The project recommends MISP 2.5 on Ubuntu 24.04 with its provided installer, and also lists Docker images, Ansible roles, Puppet and RPM packages. Whichever path you take, the work after the install is where the time goes: defining distribution levels and sharing groups, agreeing which attributes can leave your organization, configuring synchronization with each partner, and tuning correlation and default feeds so analysts are not buried in noise. Identity is a separate task. MISP's OidcAuth plugin README describes OpenID Connect login, so confirm the identity provider, claim mapping and role assignment with your identity team before go-live. The DeployOpen approach is to plan and implement these steps inside your own infrastructure under a fixed-scope written agreement, with timelines taken from that scope.

TheHive 5 is a larger deployment. It runs TheHive with Apache Cassandra and Elasticsearch, each on the JVM with its own heap configuration, and StrangeBee recommends 100 GB of storage for most use cases, so capacity planning and backup design come early. Cortex is a separate component that needs deploying and connecting, and its analyzers need network and credential decisions. Licensing is a step people forget. Installing TheHive on-premises starts a 14-day Platinum trial, after which the platform goes read-only until a valid license is applied, and Community users must request a Community license from the StrangeBee license portal. Request licensing early in the plan. The MISP connection is configured last, once both sides are stable.

Projects usually run long in four places. Sync agreements with partner organizations are negotiated outside your control, and every partner's distribution rules must be settled before data flows. Data quality is the second risk: imported indicators from feeds and partners often carry stale, duplicate or poorly typed attributes, which creates alert noise in TheHive if left unfiltered. Third, licensing lead time can delay a go-live if it is not requested at the start. Fourth, the operational setup of Cassandra and Elasticsearch, including clustering, heap sizing, snapshots and upgrades, is often underestimated by teams that have only run MISP. Ask any implementation partner for a written scope that names these items, who owns each one, and what is excluded.
