// THREAT DETECTION AND DATA PRIVACY TERM
Security Protocol
A security protocol is a set of rules that governs how computers or other devices securely transmit information over a network. It ensures that data remains confidential, unaltered, and that the parties communicating are who they claim to be.
TECHNICAL DEFINITION
A security protocol is a defined set of rules, algorithms, and cryptographic methods used in communication systems to secure data transmission across a network. Key functions include establishing authentication, ensuring data integrity, providing confidentiality through encryption, and managing session keys, with common examples being TLS/SSL for web traffic, IPsec for network-layer security, and SSH for secure remote access.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.

USAGE NOTE
This is a general term; it's crucial to specify which protocol (e.g., TLS 1.3, SSHv2) is being used for a particular application or security requirement.
DEVELOPERS
Organizations developing technology related to Security Protocol.
A standards organization that develops and promotes voluntary Internet standards, including fundamental security protocols like Transport Layer Security (TLS), IP Security (IPsec), and DNS Security Extensions (DNSSEC).
A U.S. government agency that develops cryptographic standards and guidelines that are the foundational building blocks for secure protocols. They standardize algorithms like AES and are leading the post-quantum cryptography (PQC) standardization process.
A web infrastructure and security company that is a major implementer and proponent of modern security protocols. They have been instrumental in the widespread adoption of TLS 1.3, QUIC (HTTP/3), and encrypted DNS technologies like DNS over HTTPS.
The non-profit organization behind the Signal Protocol, a state-of-the-art cryptographic protocol that provides end-to-end encryption for voice calls, video calls, and instant messaging conversations. It is used by Signal, WhatsApp, and others.
A multinational technology conglomerate that develops, manufactures, and sells networking hardware, software, and telecommunications equipment. They develop and implement numerous security protocols, from VPN technologies like IPsec and AnyConnect to secure routing protocols.
A technology company that has developed and driven the adoption of key web security protocols. It was the original developer of the QUIC protocol, the basis for HTTP/3, and is a major force in promoting universal encryption via TLS and DNS security.
A global cybersecurity company that provides advanced firewalls and cloud-based offerings. Their platforms rely on the deep inspection and implementation of various security protocols to identify and block threats.
The non-profit entity behind Let's Encrypt. ISRG developed the Automated Certificate Management Environment (ACME) protocol, which automated the issuance and renewal of TLS certificates, vastly increasing the adoption of HTTPS across the web.
