Plain-English definitions for web, search, AI and cyber security.
The terms Caribbean business owners meet most often — explained clearly, with no jargon and no sales pitch.
Content Delivery Network (CDN)
A Content Delivery Network (CDN) is a distributed network of servers positioned around the world that cache and deliver website content from a location physically close to each visitor, reducing loading time.
Core Web Vitals
Core Web Vitals are a set of Google-defined metrics — Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift — that measure real-world loading speed, responsiveness and visual stability of a webpage.
Cyber Essentials
Cyber Essentials is a UK government-backed certification scheme, run by the NCSC via IASME, that verifies an organisation has implemented five fundamental technical controls to protect against common internet-based cyber attacks.
Domain Name System (DNS)
The Domain Name System (DNS) is the internet's directory service, translating human-readable domain names such as phoenixcaribbean.com into the numeric IP addresses that computers use to locate servers.
Endpoint Detection and Response (EDR)
Endpoint Detection and Response (EDR) is security software installed on laptops, servers and other devices that continuously monitors for suspicious behaviour, alerts on likely threats, and can isolate or roll back an affected device automatically.
Generative Engine Optimisation (GEO)
Generative Engine Optimisation (GEO) is the practice of structuring a website so AI answer engines such as ChatGPT, Copilot, Gemini and Perplexity can find, understand, trust and cite it in generated answers.
Headless CMS
A headless content management system (CMS) stores and manages content through an API, separated from the presentation layer, so the same content can be delivered to a website, app or any other channel without being tied to a single front-end template system.
LLM Citation
An LLM citation is a mention, quote or reference to a specific source that a large language model includes when generating an answer, sometimes shown to the user as a clickable source link.
Multi-Factor Authentication (MFA)
Multi-factor authentication (MFA) requires a user to prove their identity with two or more independent methods — typically something they know, something they have, and something they are — before granting access to an account or system.
Phishing Simulation
A phishing simulation is a controlled, authorised fake phishing email or message sent to an organisation's own staff to measure and improve how well they recognise and report real phishing attempts.
Recovery Time Objective and Recovery Point Objective (RTO/RPO)
Recovery Time Objective (RTO) is the maximum acceptable time to restore a system after a disruption, and Recovery Point Objective (RPO) is the maximum acceptable amount of data, measured in time, that an organisation can afford to lose.
Retrieval-Augmented Generation (RAG)
Retrieval-Augmented Generation (RAG) is an AI technique in which a large language model retrieves relevant documents from an external source at the moment it answers a question, then uses them to ground its response instead of relying only on what it learned during training.
Schema Markup
Schema markup is structured data, following the shared vocabulary published at schema.org, that is added to a webpage's code to explicitly label what its content means — such as a business, a service, a review or a question and answer — so search engines and AI systems can parse it reliably.
Search Engine Optimisation (SEO)
Search Engine Optimisation (SEO) is the practice of improving a website's structure, content and authority so it ranks higher in unpaid search engine results for relevant queries.
Zero Trust
Zero Trust is a cyber security model that assumes no user, device or network location should be trusted by default, requiring every access request to be verified explicitly regardless of whether it originates inside or outside the organisation's network perimeter.
