Announcement 02 · The networkProtective DNS filtering

The safest malicious website is the one that never loads.

Every time you open a site, your computer first asks a directory service to turn the name into an address. That lookup happens before a single byte of the page arrives — which makes it the cheapest place to stop something dangerous. The new layer answers those lookups, checks the destination's reputation, and simply declines to answer for known-bad ones.

Step one
Lookups get redirected
On the office network and on laptops that leave it. Protection follows the device to home offices, hotels, and coffee shops.
Step two
Each name is scored
Against live threat feeds and behavioral signals — including domains registered hours ago, which is a hallmark of phishing campaigns.
Step three
Bad ones get a block page
A plain page explaining why, with a way to request review. Everything else resolves normally, in milliseconds.
What this catches — three real patterns
The near-miss domain. A link in an email points to a login page whose address is one character off from your real provider — a swapped letter, an extra hyphen, a different ending. The page is a pixel-perfect copy. You click; the lookup is refused; you get a block page instead of a credential theft.
The call home. If something malicious does land on a machine, its first move is to contact a control server for instructions. That contact starts with a lookup — and a device asking for a known control domain is both blocked and reported, turning an infection into an alert before anything is stolen.
The brand-new domain. Phishing sites are often registered the same morning they're used and abandoned by evening, to stay ahead of blocklists. Age itself is a signal: a domain that didn't exist yesterday and is asking for a password today gets treated as hostile by default.
What you'll notice
Browsing feels the same
Often marginally faster. Occasionally a site you need is blocked by mistake, especially small vendor portals and niche tools. That is a five-minute fix, not a policy argument.
What we need from you
Report blocks, don't route around them
If a legitimate work site is blocked, send us the exact address from the block page. Don't route around it with a personal hotspot or a VPN — that removes the protection for everything else you do that day.
Is my personal browsing being logged?
Lookups from company devices are recorded so blocks can be investigated. It is domain-level only — the site name, not the pages, searches, or anything you type. Use personal devices for personal browsing.
Does this replace the firewall?
No. The firewall guards the office perimeter; this follows the laptop everywhere else. Together they cover both.
Will it block social media or shopping?
Only if your organisation asks for category filtering. The default posture is security-only: malicious and fraudulent destinations, not lifestyle categories.

Questions about any of this

Ask before you work around something. If a block, a prompt, or a new step is getting in the way of your job, that's worth a two-minute conversation — the fix is usually immediate, and the workaround usually isn't safe.
