You don't need to be technical to sell this, but you do need to explain it simply. Each card says what the thing is, gives an everyday comparison, and offers a line you can use with a client. The rest of the guide builds on these.
The basics
DNS filtering
Before a computer opens a website it looks up the site's name, such as bbc.co.uk, to find where it lives. A DNS filter checks that lookup against lists of dangerous or banned sites and refuses to answer for the bad ones, so the page never loads.
Think of it as a receptionist who won't put calls through to known scammers. Quick and cheap, but they only hear the name, not the conversation.
Say it like this "We stop staff reaching dangerous or inappropriate sites before the page even loads."
The basics
Web filtering and secure web gateways
A step beyond DNS filtering. All of a device's internet traffic goes through a checkpoint in the cloud, which applies rules per person or team. Microsoft's is Entra Internet Access. With extra setup it can see full web addresses and some content.
Think of it as all post going through the company post room, where some parcels are turned away.
Say it like this "Your internet traffic is checked against your company rules, wherever staff are working."
DefensX
A browser security extension: DefensX
A small add-in inside Chrome, Edge or Firefox, plus a light agent on the computer. Because it sits inside the browser, it sees what happens on the page: the login box, the upload button, what is pasted into an AI chat. It can allow, warn or block each action. The agent also does DNS filtering for the whole device.
Think of it as a supervisor sitting at the desk beside you, rather than a guard at the front door.
Say it like this "Staff can use the web and AI tools freely, but company passwords and client data can't be handed to the wrong site."
The problem
Shadow AI
AI tools staff use without the business approving them, often on personal accounts: ChatGPT, Claude, Gemini, free summarising sites. Anything pasted into them leaves the business's control, and some use it to train their models.
Think of it as staff taking work home in a carrier bag, with nobody knowing what was in it.
Say it like this "Do you know which AI tools your staff use, and what they put into them? Very few businesses do."
The basics
DLP, data loss prevention
Rules that recognise sensitive information, such as card numbers, National Insurance numbers, client lists or documents marked Confidential, and warn or block when someone tries to send, upload or paste it somewhere it shouldn't go.
Think of it as the airport security scanner, but for data leaving the business.
Say it like this "If someone tries to paste client details into ChatGPT, they're stopped or warned first."
Microsoft
Purview
Microsoft's family of data protection and compliance tools: sensitivity labels on documents, DLP rules, retention, eDiscovery and reports on AI use. Business Premium has the basics for email, SharePoint, OneDrive and Teams. The Purview Suite extends the rules to devices, desktop apps and other websites, including AI tools.
Think of it as the company rule book and records office, applied by Microsoft across its products.
Say it like this "Purview decides what counts as sensitive and where it's allowed to go."
Microsoft
Defender for Cloud Apps
Microsoft's catalogue of over 31,000 cloud apps, each with a risk score. It finds out which apps staff use, lets you mark each one approved or banned, and can watch what happens inside the approved ones, such as blocking downloads on a personal laptop. Sometimes shortened to DfCA or MDCA.
Think of it as a guest list with a background check on every guest.
Say it like this "We can see every cloud app in use, how risky it is, and switch off the ones you don't want."
Microsoft
Defender for Business
The antivirus and threat detection on each device, included in Business Premium. It spots and stops malware, records what happened for investigation, and blocks known dangerous websites. Defender for Endpoint is the enterprise version of the same thing.
Think of it as the burglar alarm and CCTV on each computer.
Say it like this "Every device already has Microsoft's antivirus and detection; this sits alongside it."
Microsoft
Intune app protection
Rules that live inside company apps such as Outlook, Teams and OneDrive on phones. They can stop company data being copied, pasted or saved into personal apps like the ChatGPT app, even on a personal phone the business doesn't manage. Included in Business Premium.
Think of it as a locked briefcase on the phone: work stays in the briefcase.
Say it like this "Staff can use their own phones for email without company data leaking into their personal apps."
Technical, but it comes up
TLS inspection
Almost all web traffic is encrypted. To look inside it, a web gateway has to decrypt it, check it and encrypt it again, which needs a company certificate installed on every device. Some apps refuse to work when this happens and have to be left uninspected. DefensX avoids this by working inside the browser.
Think of it as the post room opening sealed envelopes to check them, then resealing them.
Say it like this "To look inside encrypted traffic, Microsoft's route needs extra setup on every device; DefensX doesn't."
The problem
Credential phishing and passkeys
Credential phishing is a fake login page, often a copy of the Microsoft sign in, built to steal passwords. New ones appear hourly and aren't on any blocklist yet. A passkey is a sign in method tied to the device and the real website, so it can't be typed into a fake page.
Think of it as a fake bank branch, and a key that only fits the real bank's door.
Say it like this "With passkeys and the right browser protection, even a convincing fake login page can't get a usable company password."
Microsoft
Conditional Access and the compliant network check
Conditional Access is Business Premium's rule book for signing in: who can sign in, from what device, and with what checks, such as MFA. The compliant network check adds one more rule: Microsoft 365 sign ins must come through the client's own Global Secure Access tunnel. A password or session stolen by a fake login page then fails when an attacker tries to use it from their own computer. It needs only the Microsoft traffic profile, which Business Premium includes.
Think of it as a key card that only works when you come in through the staff entrance.
Say it like this "Even if someone's login is stolen, it won't work from anywhere but your own devices."
People
Security awareness training
Short, regular training so staff recognise scams, plus phishing simulations: realistic fake emails, sent by Huntress on M-Tech's behalf, to see who clicks, followed by quick coaching. Huntress runs this for M-Tech clients and reports results.
Think of it as a fire drill for email.
Say it like this "Your people become a defence rather than the weak spot, and you have the reports to prove it."
People
Password manager: Keeper
A secure vault for every password, shared safely within teams, filled in automatically only on the genuine website it belongs to. Staff open it with their Microsoft sign in, and leavers lose access automatically.
Think of it as a key safe that only opens at the right door.
Say it like this "No more passwords in spreadsheets or on sticky notes, and nothing walks out when someone leaves."
DefensX step ups
Remote browser isolation
Opening a risky website in a browser that runs in the cloud, so only a picture of the page reaches the user's computer. Anything harmful on the site never touches the device. In DefensX Premium.
Think of it as handling a suspicious parcel through a glove box.
Say it like this "Finance can open the odd unknown link safely without risking the whole network."
DefensX step ups
Private access to office systems
Letting someone reach a specific internal system, such as an office file share or accounts server, after checking who they are, without connecting them to the whole office network like a VPN does. The industry files this under ZTNA, zero trust network access; DefensX sells it as ZTNA or ZTBA in Premium+, and Microsoft's version is Entra Private Access. How DefensX private access works.
Think of it as a key to one room rather than to the whole building.
Say it like this "Staff and contractors get exactly what they need from home, and nothing else, without a VPN."
The big idea
Zero trust
A way of designing security, not a product. Nobody is trusted just because they're on the office network or signed in once. Every request is checked against who the person is, what device they're on and what they're trying to reach; people get only the access they need; and the checks keep going, on the assumption that something may already be compromised.
Think of it as a building where every door checks your badge, not just the front entrance.
Say it like this "Zero trust isn't something you buy in one box. We build it in at every layer: sign in, devices, the web, your data and remote access."
In the M-Tech stack: Conditional Access and MFA check every sign in; the compliant network check ties sessions to the client's devices; Intune checks device health and protects data in phone apps; DefensX checks every web page, upload and AI prompt; private access replaces network-wide VPNs with access per system.
