The Massachusetts Department of Criminal Justice Information Services (DCJIS) will work with vendors interested in becoming approved hardware and/or software vendors for authorized law enforcement and criminal justice agencies.  Approved vendors offer CJIS, National Crime Information Center (NCIC), and International Justice and Public Safety Network (Nlets), access to authorized criminal justice agencies through in-station systems and/or through mobile data terminals and portable handheld devices.  

Connecting Hardware Equipment and/or Software to the CJIS Network

Criminal justice agencies and their selected vendors must get approval from the DCJIS before accessing any information on, or connecting any hardware or software to, the CJIS network. 

The CJIS Vendor Policy Guidelines pdf format of CJIS Vendor Policy Guidelines
provide step-by-step instructions for agencies and their vendors to follow to request and receive approval.  This process must be followed initially as well as at any time an agency/vendor wishes to implement additional CJIS functionality (e.g., implement a new CJIS query in an existing system).

For vendors, the approval process includes, but is not limited to:

  • Agency Support Letter:  Working with one or more criminal justice agencies who will provide a letter of agency support that describes what functionality is being requested and why.  This letter must be signed by the Police Chief or Agency Head.
  • Proposed Scope Template:  Working with the criminal justice agency to develop and submit a proposal of the scope of the technology to be implemented using the CJIS Vendor Proposed Scope pdf format of Proposed Scope Template
file size 1MB template. 

If your scope proposal is approved by the DCJIS for development and testing:

  • Development/Testing:  Developing and testing the functionality for which you are approved.  This includes working with the criminal justice agency and the EOPSS Office of Technology and Information Service (OTIS) to connect to a test CJIS environment.  It also includes preparing for, and participating in, demonstration tests of the functionality with the criminal justice agency and the DCJIS.
  • Security Standards:  Working with your criminal justice agency and the DCJIS to ensure that your personnel understand and comply with DCJIS and FBI security standards both initially and on an ongoing basis.  See the FBI CJIS Security Policy for additional information.
  • Name/Address Changes:   Keeping the DCJIS informed about any changes to your organization, including a change to your organization's name, location, and/or contact person.

CJIS Broker

To facilitate the sharing of criminal justice information in a device and presentation- independent manner, the DCJIS has developed the CJIS Broker.  The CJIS Broker is Message Oriented Middleware (MOM) that is part of a larger initiative at the DCJIS to move towards a service oriented architecture (SOA). 

In Massachusetts, all connections to NCIC, Nlets, and other information sources must go through the CJIS Broker.
