Nixle is the first authenticated service for location based information. It is a secure and indentity-certified communication service that allows local, county and state law enforcement and government agencies to connect with local residents over cell phone, email and web. Information is delivered in real time to geographically targeted consumers.
Nixle's primary publishers are local public safety agencies, municipal governments, schools and affiliated municipal agencies (e.g., emergency management, local government, public works, hospitals and recreation departments.) Nixle plans to set the foundation for a comprehensive set of location based information, which is the core of Nixle for every location throughout the world.
Nixle was founded in 2007 by Craig Mitnick.
In June of 2008, Nixle partnered with the non-profit organization NLETS, a computer-based message switching system that links together all local, state and federal law enforcement agencies throughout the United States.
Under the relationship, Nlets will house Nixle servers in their secure facilities and integrate Nixle technology into their network.
Nixle tested its technology in the winter of 2008 in Chula Vista, California. The test included publishers from the Chula Vista Police Department, Communications Department and various other Chula Vista municipal agencies. After the 45 day test, the City of Chula Vista formerly became the first municipality to adopt the Nixle platform. 
Chula Vista Mayor Cheryl Cox had this to say about the test:
"thanks to Nixle, our residents know what's happening in their city--from local emergencies and traffic advisories to upcoming cultural events and public workshops. And they get their information instantly.."
"Thousands of Chula Vistans are getting secure, reliable messages directly from our departments. Wherever I go, I run into satisfied Nixle subscribers. Residents are pleased their city is communicating with them."
In the Spring of 2009, agencies in eight states tested the new communication platform. 20 municipalities in California, following Chula Vista's lead, gained secure access to the service for testing, including Beverly Hills, Pasadena, Napa, San Diego, Sonoma, National City, Escondido and Walnut Creek.
Shortly thereafter, Nixle partnered with VeriSign Messaging and Mobile media, a division of VeriSign, Inc. VeriSign provides Nixle users with short message services (SMS), or text messaging that is built on authenticated and secure foundations.
Later that month, Nixle was one of four select sponsors at the 2009 Police Executive Research Forum's (PERF) annual meeting in Washington, D.C.  The conference was held on March 26th and 27th of 2009, hosting the nation's top 200 law enforcement executives from the largest cities in the country. 
Nixle partnered with the National Sherrif's Association (NSA) at the 69th Annual Conference held in Fort Lauderdale. At the conference, users could text the word "sheriff" to a phone number and receive alerts to their cell phones throughout the Greater Fort Lauderdale Convention Center.
After some strategic partnerships with NLETS, VeriSign, and Hillard Heintze, Nixle began rolling its service out to agencies nationwide.
By the summer of 2009, Los Angeles, Baltimore, Chicago, Virginia Beach, Minneapolis, and another 800 cities in 43 states had either adopted the program or were testing it.
At the 2009 G20 Summit , Nixle's services enabled the Pittsburgh police department to communicate with 30 agencies for the event, quelling protester hot spots and keeping the damage to the city at a minimum.
Nixle's public safety alerts have reached residents and communities across the country. One of the earliest examples of the Nixle service occurred in Chula Vista.
Chula Vista Missing Woman
A senior citizen went out to check the mail and never came back in. Her husband, worried about her recent episodes, called police. CVPD issued the first of two Alert messages, asking folks to keep an eye out for a disoriented elderly woman wearing yellow shorts. The message was sent within a ½ mile of her home. 45 minutes later, CVPD sent a follow-up message with a complete description of the woman and a picture, widening out the message distribution area to 2.5 miles. A citizen received the message and saw the woman, allowing CVPD to bring her home safely.
Nixle's servers are all located at NLETS, providing added security from would-be-hackers. This enables local police departments nationwide to send immediate alerts and advisories using their secure police terminals.
Nixle does not access Nlets' law enforcement information, they access their infrastructure. Nixle is designed on an emergency-grade platform hosted directly at the Nlets data center in Phoenix, Arizona, which features an on-site diesel generator for power failover, a Cisco firewall system and highly secured and tightly regulated physical access to the facility. Nixle's partnership with Nlets allows Nixle to provide access to police and fire agencies across the United States on their private network in their vehicle or handhelds without internet access.
Nixle's technology platform creates a database of community information that builds upon itself. As municipal and community oriented groups push out their location-specific information directly to communities, the system also archives. This creates the foundation for databases of local news and information.
Information is disseminated to any point or address in a desired geographic area. This technology is also available to consumers.
The municipal wire delivers information exclusively from public safety agencies and municipal governments. Advertising and other sets of information are not comingled within the Municipal wire so as not to diminish the integrity of public safety and government information.
The Community Wire
Residents within community groups like sports leagues, youth organizations, or any socially oriented groups are eligible to publish information into the community wire through Nixle.
The Restaurant and Retail Wires
Users choose to receive notices local from restaurants and retailers. Allows companies to market products and services in a way that is both time-sensitive and location-sensitive.
Secure Group Text Messaging
Nixle's Private Messaging application allows agencies and organizations to use the same trusted Nixle platform for public messaging to communicate internally via private groups. Agencies and organizations can define custom groups and use mobile phone texts messages (SMS) to keep group members up-to-date with real-time messages on mobile phones. Nixle's Private Messaging application will be rolled out at the multi-nation/multi-agency G-20 Summit in Pittsburgh in September 2009.
