Everything between you and the bad internet.

Threat blocking, tracker removal, family filters, per-device rules, time-based schedules, and a dashboard that shows exactly what was stopped. Here is what is live today, and what is on the way.

Stops scams before they load

Phishing pages, fake bank logins, malware downloads, and ransomware sites are blocked at the DNS level, before your browser ever connects. Curated threat blocklists update automatically, and you can block entire top-level domains (like .xyz or .top) that scammers love. When something is stopped, you get a clear explanation page instead of a mysterious failure.

How our blocking works

Available now

Ads and trackers, gone

The invisible trackers that follow you across the web are cut off at the source, along with pop-ups and auto-play ad networks. Pages load faster, your battery lasts longer, and nobody builds a profile on you.

Available now

Family protection that just works

Turn on the family filter once to block adult content, gambling, and known scam sites across every device in the house. Give each kid their own profile with per-device rules, enforce SafeSearch and YouTube Restricted Mode, and set homework-time and bedtime schedules that apply automatically. Rules can differ by device, so the living-room TV and a teenager's phone do not have to share the same policy.

Available now

A dashboard that shows everything

See blocked threats, top trackers, and per-device activity in real time from your dashboard at my.korushield.com. Drill into query logs by device, domain, or time, allow or block a domain right from the log with one click, and export your history to CSV whenever you want.

Available now

Encrypted and fast by default

Every lookup travels over encrypted DNS (DoH) through our US servers in Northern Virginia and Oregon. Each device gets its own private resolver token, so policies follow the device without leaking who is who. Checks complete in milliseconds, and plain unencrypted DNS is refused entirely, so nothing leaks around the protection.

Available now

Schedules that parent for you

Set it once and forget it. Block social media during homework hours, shut off gaming at bedtime, or open everything up on weekends. Schedules attach to any rule or profile, respect daylight saving time, and warn you before overlapping rules fight each other.

On the roadmap

Preview changes before they go live

Wondering what happens if you block a whole category? The policy simulator shows you exactly which domains would be affected, on which devices, before you commit. Every change is versioned too, so you can roll back to any earlier policy in one click.

For people who tinker

Built for people who tinker.

Policy simulator

Before you publish a rule change, preview exactly which domains it would affect and on which devices. No more guessing what a category block will break.

Versioned policies, staged rollouts

Every policy change is versioned automatically. If a change does not behave the way you expected, roll back to any earlier version in one click.

TLD blocking

Block entire top-level domains outright, like .xyz or .top, the ones scammers love to register in bulk. One rule covers a whole category of throwaway domains.

On the roadmap

Lookalike domain detection

Mark a domain as protected and Koru Shield will watch for typosquat variants designed to impersonate it, catching lookalikes aimed at your bank, workplace, or favorite sites.
