Colorado Information Sharing Consortium (CISC)

The Colorado Information Sharing Consortium (CISC) is a separate legal government entity created on April 7, 2014, when eleven Colorado law enforcement agencies signed an Intergovernmental Agreement under C.R.S. § 29-1-203(4). The founding members included the Adams, Arapahoe, and Douglas county sheriff's offices, the Board of County Commissioners of Jefferson and Mesa counties, the City and County of Denver, the cities of Aurora, Colorado Springs, Commerce City, and Grand Junction, and the Colorado Department of Public Safety. CISC is governed by an eleven-member Board of Directors drawn from sheriffs, police chiefs, and command staff, and is headquartered in Aurora. It began on the COPLINK platform and later moved its data sharing onto LexisNexis infrastructure.

Agencies join CISC's LexisNexis arrangement by signing a "CISC Member Agency Addendum and Joinder," which makes them a party to the LexisNexis Master Terms. Under that addendum a joining agency agrees to contribute its public safety information — its "Customer Data Contribution" (Section II.2) — and grants LexisNexis a paid-up, irrevocable, worldwide, non-exclusive license to use, adapt, aggregate, and distribute that data (Section III.1). The contributed data is held in the "CISC Data Warehouse," which the contract describes verbatim as "a PSDEX private container database provided by LN" — LexisNexis's Public Safety Data Exchange.

The addendum sets out a three-tier sharing structure. Sharing with other CISC member agencies is automatic. Two further tiers are opt-in, each selected by initialing a box: sharing with LexisNexis PSDEX customers outside the CISC membership, and sharing a de-identified subset with third parties that publish public crime maps. In the Clear Creek County joinder we hold (February 2024), the agency initialed the de-identified public-map tier but left the box to share with outside PSDEX customers un-initialed — a reminder that the scope of sharing can differ from one member agency to the next.

As reported, LexisNexis acquired the Lumen public-safety platform from Numerica in 2019 and cited CISC among its customers. The consortium's footprint is large: CISC lists an estimated 124 member agencies across Colorado, of which 87 are confirmed in our research.
