What We Do


Nlets links together and supports every state, local and federal law enforcement, justice and public safety agency for the purposes of sharing and exchanging critical information.

Nlets' role in information sharing in the 21st century continues to expand and evolve. While we have always existed to facilitate criminal justice exchanges, we also serve to push the definition of what that really means. The expectation for the services we provide grows every year as technology improves and the sophistication of our user community increases. At Nlets, we are dedicated to expanding both the capacity and the reach of the network, growing our strategic partnership network with the for-profit community, and taking calculated risks to deliver new services in secure but user-friendly ways at the lowest possible cost.

Today, Nlets is also a proving ground for new and innovative information sharing technology and a trusted source for leading edge grant work to develop breakthrough programs that support the men and women who need the right information, at the right place, 24 hours a day, 7 days a week, 365 days a year.

Nlets utilizes a Multi-Protocol Label Switching (MPLS) for superior connectivity and dependability, providing a minimum of at full T1 speed to all its customers with a robust wireless backup capability to all users to ensure network uptime is at or above the critical needs of the field.  Nlets provides the latest security protocols including AES 256 bit encrypted connectivity to Nlets member agencies, enhancing inter-agency information sharing capabilities.

Nlets Transactions
Through the Nlets network, law enforcement and criminal justice agencies can access a wide range of information, from standard driver license and vehicle queries to criminal history and Interpol information. The array of services we provide is constantly expanding as we strive to meet the growing demands for information by the agencies that protect life and liberty.

Below are just three of over 100 transactions available over the Nlets network.


Interpol Query


By working with Interpol Nlets provides law enforcement the secure and instantaneous means to electronically exchange critical international information between the US and the Interpol database in Lyon, France.  With this tool law enforcement is provided with real-time, roadside access to international warrants, stolen vehicles, stolen passports and other travel documents from around the globe. This access immediately enhances officer safety and makes them more effective on the roadside or in an investigation.

The Interpol queries through Nlets query against the Interpol Automated Search Facility (ASF) for persons (wanted, suspected and missing, as well as some criminal history information), vehicles and lost or stolen travel documents. The information returned from the query will be limited and the USNCB will need to be contacted for additional details on positive matches.

While Nlets is able to support this message key in all states, not every state has implemented the Interpol transaction, and even fewer have federated the message to send the automatic query simultaneously with other queries transmitted across the network.

If you are interested in this transaction, please email messagekeys@nlets.org.

Requests from local agencies interested in using the federated Interpol message key must be reviewed by the Nlets state representative.

General Person Query


A Law Enforcement Information Sharing Service (LEISS) query transaction searches ICE-PIC for person subjects to return complete biographic and biometric data on the subject. The information may be used to assist with investigations, notify requesting officials of past criminal behavior, and validate person subject key biographic and biometric information.

Queries must contain person information, location information, a telephone number, or an identifier (only one from each type may be included in a query). A successful query results in summary information (names, addresses and birth dates) that includes a unique identifier, referred to as a Data Item ID. This can be used on a secondary search to retrieve more detailed information on the individual.

Note: Adding additional elements to a search request does not have the usual outcome of narrowing or constraining the set of returned elements; rather, it could have the opposite effect of increasing the number of results returned. This is because the results are not coming directly from an operational relational database, nor a data warehouse, but actually from data results provided by a sophisticated tool (IBM's Entity Analytics Solutions [EAS]) that collects, analyzes, and resolves the data. The tool performs name recognition with cultural awareness, address cleansing, and entity resolution.

Nlets is working with LEISS to run General Person queries via the Nlets network to destination AX (ICE). These exchanges are currently set up to support queries with name, date of birth (optional), height (optional), weight (optional), location (i.e. address, city, state) and phone number (optional) as primary query fields.

If you are interested in this transaction, please email messagekeys@nlets.org.

Requests from local agencies interested in using the General Person Query message key must be reviewed by the Nlets state representative.

Automated Secure Alarm Protocol


APCO International and Central Station Alarm Association (CSAA) have developed the Automated Secure Alarm Protocol (ASAP) to provide a standard data exchange for electronically transmitting information between an alarm monitoring company and a public safety answering point (PSAP). This protocol has three primary benefit goals: eliminate the telephone calls between the alarm monitoring company operator and the 9-1-1- PSAP call-taker; eliminate miscommunication between the alarm monitoring company operator and the 9-1-1- PSAP call-taker; and realize a decrease in response times to alarm-related calls-for-service with an increase in law enforcement apprehensions made, fires more quickly extinguished, and lives saved. CSAA and APCO determined Nlets as the preferred transport of ASAP for 5 key reasons:

·         Nlets already has infrastructure in place.

·         Nlets offers safe and secure communications.

·         Nlets offers an intelligent routing scheme.

·         Nlets is already in operation with thousands of PSAPs.

·         Nlets is trusted by the PSAP community.

These exchanges average a 15 second or less turnaround time over the interface, and are piloting in Richmond, VA and Houston, TX. Currently, CAD providers and alarm monitoring software providers are starting their ramp-ups to expand the exchange beyond the initial pilot.

Nlets - CSAA High Level Design:

·         XML Firewall housed within the Nlets facility

·         Secure Certificate Authenticated hardware based to VPN's Central Stations

·         CSAA Message Broker Server to consolidate ASAP traffic housed within the Nlets site

·         Nlets routing "wrapper" (use of ORIs)

If you are interested in this transaction, please email messagekeys@nlets.org.

Requests from local agencies interested in using the ASAP message key must be reviewed by CSAA and the Nlets state representative.
