Technology Glossary

Plain-English IT

Speak fluent IT in five minutes

The technology industry produces acronyms faster than products — here’s what the important ones actually mean for your business, no decoder ring required.

Security

MDR — Managed Detection & Response

A team of security analysts watching your environment 24/7, hunting threats and responding to incidents. Think of it as renting a world-class security operations center instead of building one.

SASE — Secure Access Service Edge

Networking and security delivered together from the cloud, so protection follows your people wherever they work. It’s the office perimeter, minus the office.

ZTNA — Zero Trust Network Access

A security model built on “never trust, always verify” — every user and device proves itself before touching anything. One stolen password shouldn’t open every door, and with ZTNA it doesn’t.

EDR — Endpoint Detection & Response

Behavior-based protection for laptops and servers that spots an attack in progress and isolates a compromised machine in seconds. Traditional antivirus checks IDs at the door; EDR watches what everyone does once they’re inside.

Cloud & infrastructure

IaaS — Infrastructure as a Service

Renting compute and storage from a provider instead of buying and maintaining your own servers. You get capacity on demand, and the hardware headaches become someone else’s job description.

Colocation

Your servers, housed in a professional facility with enterprise-grade power, cooling, and connectivity. You keep control of the hardware without babysitting the building it lives in.

DRaaS — Disaster Recovery as a Service

A continuously updated copy of your critical systems, standing by to take over in minutes when disaster strikes. It’s the insurance policy that actually pays out.

FinOps — Cloud Financial Operations

The discipline of making cloud spend visible, accountable, and optimized. Cloud bills grow like garden weeds — FinOps is how you keep the garden.

Network

SD-WAN — Software-Defined Wide Area Network

Smart routing across all your internet connections, sending traffic down the best path automatically. Your applications stay fast even when one circuit is having a bad day.

DIA — Dedicated Internet Access

Internet bandwidth that’s all yours, with guaranteed speeds and service levels. Unlike shared broadband, where “up to” does a lot of work in the sales brochure.

NaaS — Network as a Service

Your entire network — hardware, management, and monitoring — delivered as a subscription. Predictable costs, current equipment, and no forklift upgrade every five years.

Communications

UCaaS — Unified Communications as a Service

Phone, video, chat, and meetings in one cloud platform — minus the closet of blinking boxes. Your team communicates from anywhere, and your phone system stops being a maintenance project.

CCaaS — Contact Center as a Service

A cloud contact center with intelligent routing, analytics, and AI built in. Better customer conversations, and numbers your operations team can actually see and manage.

CPaaS — Communications Platform as a Service

APIs that let your applications send texts, make calls, and verify users. It’s the plumbing behind every “your table is ready” text you’ve ever received.
