WheelGroup was a computer security company with approximately 65 employees based in San Antonio, Texas. The 10 founders originally met and worked together at the US Air Force Information Warfare Center and many of them subsequently worked at Trident Data Systems. Taking technology out of what they'd been working on at Trident, they started Wheelgroup in November 1995. WheelGroup was one of the first companies to specialize in network security and penetration testing[citation needed].
The company developed and sold the first[citation needed] commercial intrusion detection system, NetRanger, which was the flagship intrusion detection software at Cisco Systems and which has now been re-engineered, and re-branded, as the Cisco Systems Adaptive Security Appliance.
WheelGroup also created the first[citation needed]Python based network vulnerability scanner, NetSonar, which was later re-branded and sold as the Cisco Network Security Scanner. WheelGroup was acquired by Cisco Systems for $124million on March 12, 1998. Since the acquisition of WheelGroup, the original founders have all moved on to positions at other computer security companies, or started their own computer security companies. Kevin Ziese passed in February, 2017

An intrusion detection system is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms.
Antivirus software, also known as anti-malware, is a computer program used to prevent, detect, and remove malware.
A personal firewall is an application which controls network traffic to and from a computer, permitting or denying communications based on a security policy. Typically it works as an application layer firewall.
Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly. Deep packet inspection is often used for baselining application behavior, analyzing network usage, troubleshooting network performance, ensuring that data is in the correct format, checking for malicious code, eavesdropping, and internet censorship, among other purposes. There are multiple headers for IP packets; network equipment only needs to use the first of these for normal operation, but use of the second header is normally considered to be shallow packet inspection despite this definition.
ESET, s.r.o., is a Slovak software company specializing in cybersecurity. ESET's security products are made in Europe and provide security software in over 200 countries and territories worldwide, and its software is localized into more than 30 languages.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: it secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.
Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS) created in 1998 by Martin Roesch, founder and former CTO of Sourcefire. Snort is now developed by Cisco, which purchased Sourcefire in 2013.
A host-based intrusion detection system (HIDS) is an intrusion detection system that is capable of monitoring and analyzing the internals of a computing system as well as the network packets on its network interfaces, similar to the way a network-based intrusion detection system (NIDS) operates. This was the first type of intrusion detection software to have been designed, with the original target system being the mainframe computer where outside interaction was infrequent.
Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network. The most common type is Wi-Fi security, which includes Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is an old IEEE 802.11 standard from 1997. It is a notoriously weak security standard: the password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP was superseded in 2003 by WPA, a quick alternative at the time to improve security over WEP. The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device that encrypts the network with a 256-bit key; the longer key length improves security over WEP. Enterprises often enforce security using a certificate-based system to authenticate the connecting device, following the standard 802.11X.
Network Chemistry was a Wi-Fi security startup based in Redwood City, California. The firm was founded in 2002 by several co-founders including Gary Ramah, Rob Markovich and Dr. Christopher Waters and is backed by venture capital firms such as San Francisco-based Geneva Venture Partners, Innovacom and In-Q-Tel, the investment arm of the CIA.
