AppShield was an early Web application Firewall. [1] AppShield was conceptualized by Eran Reshef and Gili Raanan and was introduced to the market by Perfecto Technologies (now Sanctum) in the summer of 1999. [2] AppShield worked by inspecting incoming HTTP requests and blocking malicious attacks based on a dynamic policy which was composed by analyzing the outgoing HTML pages. [3] [4] [5] A 2002 ZDNet article noted that in the three years following its launch, it had been used by 60 Fortune 100 companies. [6]
Watchfire acquired Sanctum in 2004, and subsequently sold the intellectual property for AppShield to F5 Networks, which discontinued the product in favor of its competing TrafficShield product. [7]
Instant messaging (IM) technology is a type of synchronous computer-mediated communication involving the immediate (real-time) transmission of messages between two or more parties over the Internet or another computer network. Originally involving simple text message exchanges, modern IM applications and services tend to also feature the exchange of multimedia, emojis, file transfer, VoIP, and video chat capabilities.
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.

Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet is an inherently insecure channel for information exchange, with high risk of intrusion or fraud, such as phishing, online viruses, trojans, ransomware and worms.
An application firewall is a form of firewall that controls input/output or system calls of an application or service.
