IT & Technology Glossary
Technology is full of confusing acronyms. Use our comprehensive A-Z dictionary to translate complex IT jargon, cybersecurity concepts, and cloud computing principles into plain English.
API (Application Programming Interface)
A set of rules that allows two different software applications to talk to each other. For example, when you use PayPal to buy something on an e-commerce website, an API is what allows the store to securely communicate with PayPal. In modern enterprise architecture, APIs are the foundational building blocks that allow disparate systems (like an ERP and a bespoke mobile app) to share real-time data seamlessly.

A set of policies and procedures designed to ensure that an organization's critical business functions continue to operate during and after a disaster (such as a ransomware attack or hardware failure). True BCDR doesn't just back up data; it dictates exactly how quickly systems can be restored (Recovery Time Objective) and how much data loss is acceptable (Recovery Point Objective).
Learn more about our related servicesBlockchain
A digital ledger distributed across a network of computers. It records transactions immutably (meaning they cannot be altered or deleted), providing absolute transparency and security without the need for a central authority. It is widely used beyond cryptocurrency for smart contracts, supply chain provenance, and secure data sharing.
Learn more about our related servicesCI/CD (Continuous Integration / Continuous Deployment)
A software engineering practice where developers frequently merge code changes into a central repository (Continuous Integration), after which automated builds and tests are run. Continuous Deployment then automatically releases these validated changes to production environments, drastically speeding up the software release cycle and reducing bugs.
Learn more about our related servicesCloud Computing
The delivery of computing services (servers, storage, databases, networking, software) over the internet ('the cloud') rather than hosting them on local, physical servers in your office. The three leading public cloud providers are AWS, Microsoft Azure, and Google Cloud Platform (GCP).
Learn more about our related servicesContainerization (Docker & Kubernetes)
A modern software deployment method where an application and all its necessary dependencies (libraries, frameworks) are packaged together into a 'container'. Unlike traditional virtual machines, containers are incredibly lightweight. Kubernetes is the orchestration tool used to automatically manage, scale, and deploy thousands of these containers in production environments.

A UK Government-backed certification scheme that helps organizations protect themselves against common cyber attacks. Achieving Cyber Essentials (and the more rigorous Cyber Essentials Plus) is often mandatory for bidding on UK government contracts and demonstrates baseline cybersecurity hygiene.
Learn more about our related servicesDDoS Attack (Distributed Denial of Service)
A malicious attempt to disrupt normal traffic to a web server or network by overwhelming it with a massive flood of internet traffic, causing the site to crash or become unresponsive to legitimate users. These attacks are typically executed using networks of compromised computers (botnets).
Learn more about our related servicesEDR (Endpoint Detection and Response)
Advanced cybersecurity software installed on individual devices (endpoints like laptops, servers, and mobile devices). Unlike legacy antivirus that only stops known threats, EDR uses behavioral analysis to constantly monitor for and automatically respond to advanced, previously unknown cyber threats like zero-day ransomware.

A type of artificial intelligence capable of generating novel text, images, code, or other media in response to prompts. Examples include ChatGPT, Claude, and Midjourney. In enterprise environments, GenAI is typically integrated via APIs to automate customer service, generate reports, or assist in complex data analysis.
Learn more about our related servicesIaaS (Infrastructure as a Service)
A cloud computing model where you rent raw computing infrastructure (like virtual servers, storage, and networking) from a provider like AWS or Azure, rather than buying physical hardware. You are responsible for managing the operating systems and applications running on this infrastructure.
Learn more about our related servicesISO 27001
The international gold standard for Information Security Management Systems (ISMS). It provides a rigorous framework for keeping information assets secure through strict organizational policies, risk assessments, and technical controls. Achieving certification is a powerful trust signal for enterprise B2B sales.

An enterprise cloud architecture that utilizes two or more public cloud providers (e.g., using AWS for machine learning and Azure for Windows workloads) to avoid vendor lock-in, optimize costs, and increase redundancy and disaster resilience.
Learn more about our related servicesPenetration Testing (Pen Test)
An authorized, highly skilled simulated cyberattack on a computer system, performed by ethical hackers to evaluate the security of the system and proactively identify complex logic flaws and vulnerabilities before malicious hackers can exploit them.
Learn more about our related servicesPhishing
A type of social engineering attack where criminals send fraudulent emails designed to trick people into revealing sensitive information, such as passwords or bank details. Spear-phishing is a highly targeted version aimed at specific executives or departments.
Learn more about our related servicesRansomware
Malicious software that infiltrates a network and violently encrypts a victim's files, rendering them unreadable. The attacker then demands a ransom (usually in cryptocurrency) to provide the decryption key. Modern ransomware gangs also steal the data and threaten to leak it publicly if the ransom is not paid (double extortion).
Learn more about our related servicesSaaS (Software as a Service)
A software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted in the cloud. Users access the software via a web browser. Examples include Microsoft 365, Salesforce, and Google Workspace.
Learn more about our related servicesSLA (Service Level Agreement)
A formal, legally binding contract between a service provider and a client that dictates the specific standards of service expected. In IT, an SLA typically guarantees specific uptime percentages (e.g., 99.99%) and maximum response times for technical support tickets.
