A part of the Cisco Unified Services Delivery Solution that will include hosted versions of Cisco Unified Communications Manager (UCM), Cisco Unified Contact Center, Cisco Unified Mobility, Cisco Unified Presence, Cisco Unity Connection (unified messaging), and Cisco Webex Meeting Center.

Network Emergency Response
The company maintains several Network Emergency Response Vehicles (NERV)s which are staffed by Cisco employees during natural disasters and other public crises. The vehicles are self-contained and provide wired and wireless services including voice and radio interoperability, voice over IP, network based video surveillance and secured high definition video conferencing for leaders and first responders in crisis areas with up to 5 Mbit/s of bandwidth via a 1.8-meter satellite antenna. NERVs are normally stored at Cisco facilities in San Jose, California and Research Triangle Park, North Carolina for strategic deployment in North America and are capable of being fully operational within 15 minutes of arrival, running for 72 hours continuously. The NERV has been deployed to incidents such as the October 2007 California wildfires; hurricanes Gustav, Ike, and Katrina; the 2010 San Bruno gas pipeline explosion, tornado outbreaks in North Carolina andAlabama in 2011; and Hurricane Sandy in 2012. In 2011, Cisco received the Innovation Preparedness award from the American Red Cross, Silicon Valley Chapter for its development and use of these vehicles in disasters.

Cisco Career Certifications
Cisco Systems also sponsors a line of IT Professional certifications for Cisco products. There are five levels of certification: Entry (CCENT), Associate (CCNA / CCDA), Professional (CCNP / CCDP), Expert (CCIE / CCDE), and recently Architect, as well as eight different paths, Routing & Switching, Design, Network Security, Service Provider, Service Provider Operations, Storage Networking, Voice, and Wireless.

A number of specialist technician, sales and datacenter certifications are also available.

Cisco also provides training for these certifications via a portal called the Cisco Networking Academy. Qualifying schools can become members of the Cisco Networking Academy and then provide CCNA level or other level courses. Cisco Academy Instructors must be CCNA certified to be a CCAI certified instructor.

Criticisms and controversy
Shareholder relations
A class action lawsuit filed on April 20, 2001 accused Cisco of making misleading statements that "were relied on by purchasers of Cisco stock" and of insider trading. While Cisco denied all allegations in the suit, on August 18, 2006, Cisco's liability insurers, its directors, and officers paid the plaintiffs US$91.75 million to settle the suit.

Intellectual property disputes
On December 11, 2008, the Free Software Foundation filed suit against Cisco regarding Cisco's failure to comply with the GPL and LGPL license models and make the applicable source code publicly available. On May 20, 2009, Cisco settled this lawsuit by complying with FSF licensing terms and making a monetary contribution to the FSF.

Censorship in China
Cisco has been criticized for its involvement in censorship in the People's Republic of China. According to author Ethan Gutmann, Cisco and other telecommunications equipment providers supplied the Chinese government with surveillance and Internet infrastructure equipment that is used to block Internet websites and track Chinese online activities. Cisco says that it does not customize or develop specialized or unique filtering capabilities to enable governments to block access to information and that it sells the same equipment in China as it sells worldwide.

Wired News had uncovered a leaked, confidential Cisco power point presentation that details the commercial opportunities of the Golden Shield Project of Internet control. In her article, journalist Sarah Stirland accuses Cisco of marketing its technology "specifically as a tool of repression."

Tax fraud investigation
On October 16, 2007, the Brazilian Federal Police and Brazilian Receita Federal (equivalent to the American IRS), under the "Persona Operation", uncovered an alleged tax fraud scheme employed by Cisco Systems Brazil Chief Carlos Roberto Carnevali since 2002 that exempted the company from paying over R$1.5 billion (US$824 million) in taxes.

Antitrust lawsuit
On December 1, 2008, Multiven filed an antitrust lawsuit against Cisco Systems, Inc. in an effort to open up the network maintenance services marketplace for Cisco equipment, promote competition and ensure consumer choice and value. Multiven's complaint alleges that Cisco harmed Multiven and consumers by bundling and tying bug fixes/patches and updates for its operating system software to its maintenance services (SMARTnet) and through a series of other illegal exclusionary and anticompetitive acts designed to maintain Cisco's alleged monopoly in the network maintenance services market for Cisco networking equipment. Cisco responded by accusing the person who filed the anti-trust suit, British-born Peter Alfred-Adekeye, with hacking and pressured the US government to extradite him from Canada, where he was giving evidence against Cisco in an anti-trust hearing. Canadian Judge Ronald McKinnon, who oversaw the extradition hearing, stated the real reason for the extradition proceedings was because Alfred-Adekeye "dared to take on a multinational giant."

He also condemned the US prosecutor for hiding the fact that Alfred-Adekeye was in legal proceedings against Cisco Systems, for stating that Alfred-Adekeye had left the USA in a time period when he had not and a formal request for extradition was not filed against Alfred-Adekeye when he was taken into custody. Judge McKinnon described the information provided by Cisco and the US prosecutor as "full of innuendo, half-truths and falsehoods," adding that "This speaks volumes for Cisco's duplicity" and accused them of "unmitigated gall" in using such a heavy-handed move as an unsupportable arrest and jailing to pressure Alfred-Adekeye to drop or settle his civil antitrust complaint.

Intimidation
Cisco has been reported as using intimidation tactics in several news reports.

Remotely monitoring users' connections

Cisco's Linksys E2700, E3500, E4500 devices have been reported to be remotely updated to a firmware version that allows Cisco to monitor their network use.
