DNS Filtering
The internet is full of traps.
We make sure your team
doesn't walk into them.
Secure DNS and web filtering blocks malicious websites, ransomware delivery, and phishing pages before they ever reach your devices — whether your team is in the office, working from home, or connecting from a coffee shop.

What It Does
Your first line of defence
against the web's worst corners
Most security tools try to clean up a mess after something bad has already happened. Secure DNS stops threats before they even load — no file downloaded, no malware executed, no damage done.
Block threats before they load
When something breaks, your team needs help now — not a ticket queue. We provide unlimited support hours with a single, consistent team that already knows your environment.
Enforce usage policies, everywhere
Most IT problems don't appear out of nowhere — they build. 24/7 infrastructure monitoring and automated maintenance catch issues before they become outages.

Get clear reporting on browsing activity across your organization — what sites are being visited, what's being blocked, and whether anyone's device is showing warning signs of compromise.
How It Works
It happens in the background.
You'll only notice what's missing — threats.
DNS is the internet's address book. Every time you visit a website, your device looks up that site's address. We intercept that lookup and check it against our threat intelligence before it resolves.
Someone clicks a link or types a web address
The request goes through our filtering layer before anything loads — takes under a millisecond.
We check it against real-time threat intelligence
The destination is compared against live databases of known malicious domains, phishing sites, malware distribution points, and policy categories.
Blocked or allowed — instantly
Dangerous destinations are blocked with a clear explanation. Safe sites load normally. No slowdown, no disruption to legitimate work.
We review the logs so you don't have to
Lumitiv monitors your filtering data for patterns that suggest a compromised device or high-risk behaviour — and alerts you before it becomes a problem.

What We Block
Threat categories we watch for
around the clock
Threats aren't just obvious malware sites. Modern attacks use sophisticated techniques — lookalike domains, compromised legitimate sites, and newly registered domains that haven't made it onto blocklists yet.
Phishing sites
Fake login pages designed to steal usernames and passwords
Malware
Sites that attempt to download malicious software onto your devices
Ransomware
Blocks already-infected devices from "calling home" to attackers
Cryptojacking
Sites that hijack your hardware to mine cryptocurrency
Policy Categories
Adult content, gambling, social media — configured to your policy
New Domains
Brand-new domains are frequently used for attacks before lists catch up
What's included
Common attack vectors
and how DNS filtering stops them
From password resets at 8am to a ransomware scare at 4:55pm — here's what your team gets access to.
CRITICAL
Phishing Sites
Fake login pages built to look exactly like your bank, Microsoft 365, or email provider — designed to steal credentials the moment someone types them in.
CRITICAL
Malware Distribution
Some sites exist for one purpose: to push malicious software onto your device the moment you land on them. DNS filtering stops the connection before anything downloads.
CRITICAL
Ransomware
Once ransomware is on a device, it needs to reach an attacker's server to activate. DNS filtering cuts off that call — often stopping an attack that's already begun.
High
Malvertising
Legitimate websites can unknowingly serve dangerous ads. DNS filtering blocks the malicious domains behind those ads before the code ever runs on your device.
High
Illegal Content
Torrent sites and piracy platforms are riddled with malware and create real legal exposure for your business. DNS filtering keeps your network — and your liability — clean.
Moderate
Shadow IT
Employees using unsanctioned apps or services bypass your security controls without realizing it. DNS filtering gives you visibility and control over what's actually connecting to the internet.
Remote & Mobile Coverage
Your office firewall doesn't protect your team at home.
This does.
When employees work from coffee shops, home offices, or hotels, they're connecting through networks you don't control — and your traditional office firewall does nothing to protect them there.
A lightweight agent on each device routes DNS queries through our filtering system regardless of network. Same protection in the office, at home, at the airport, or anywhere else.
Straight Talk
What you should know before you decide
This is a layer — not the whole picture.
DNS filtering is highly effective at stopping network-based threats, but it doesn't replace endpoint protection or email filtering. Think of it as one strong layer of a multi-layer approach. We'll tell you what else you need, honestly.
