See it. Understand it. Control it.

ShadowLatch shows which programs on your Windows devices connect where, tells you who owns each destination, lets you block what shouldn't be there, and gives servers a way to block intruders themselves. The same console works on your phone. Running devices for clients? See ShadowLatch for MSPs.

Home

Start with what changed.

A summary of your fleet: open Review items, devices that are offline or need an update, what was blocked in the last day, the apps and devices moving the most data, and the top destinations and services.

  • Review, device and blocked-traffic cards
  • Top talkers and busiest devices
  • One click into the detail behind each card

Flow

See every relationship at once.

Devices, applications and destinations in three connected columns. Select anything and its connections light up. Filter by device, time and service, or watch it live as new connections arrive.

  • Live mode with new connections highlighted
  • Owner and hostname for every destination
  • Blocked links shown in red

Activity

Watch it happen, then search the history.

One page for both. With Live on, every connection appears the moment it opens: time, outcome, application, destination, owner, service, location, device and user, paused while you hover and with repeats collapsed so a busy network stays readable. With Live off it is the searchable record of every connection, as far back as your plan keeps: filter by device, user, application, destination, outcome, direction and time, and export it for reports.

  • Live toggle: allowed, blocked and blocked-at-DNS side by side as they happen
  • Filters that remember themselves
  • Inbound and outbound, with the peer on either side
  • CSV export for reports

Network

Know who is on the other end.

Destinations, Services and Applications in one page. Every address your devices talked to, one row each: the names devices resolved for it, its owner and location, the category, which devices and applications reached it, on which ports, how often, how much data, and when it was first and last seen. Block the address, its owner or its whole country from the same row.

  • Owner, country and reverse DNS for each address
  • Traffic grouped by service, with what depends on it
  • Every destination an application reached, on every device

Review

Catch new behavior the day it starts.

ShadowLatch learns what's normal for your account and queues what isn't: a new application, a new destination, a new port or protocol, or an unusually large transfer.

  • No rules to write
  • Create a policy straight from an item
  • Dismiss one item or everything like it

Reports

See the month, not just the minute.

Totals and trends for any range up to a year: connections, blocks and data against the period before, a device-by-day map that shows when each machine was busy and when something was blocked, and the busiest applications, destinations and devices. Narrow it to blocked activity, the local network or inbound connections, and export it for an audit.

  • Last 7, 30 or 90 days, a year, or your own range
  • A click on any day opens it in Activity
  • CSV export of every section

Rules

One profile for each kind of device.

A profile holds everything a group of devices should do: protections, blocked categories, policy folders and alerts. Every device follows Default until you give it another profile, by company, group or device, and a single device can still differ where you allow it. Changes are staged, reviewed and applied together, with a note in the history.

  • Protections, Categories, Policies, Alerts and Applies to on one page
  • Policies live in folders that several profiles can share
  • Lock a setting so groups and devices can't change it

Policies

Say what you mean.

Block or allow from any row in Activity, Network, Review or Home: the sheet names exactly what will be blocked and where, and files it into the right profile. For anything more, the policy wizard takes a site, a URL, a service, a country or a network owner and shows in a sentence what the policy does and what it would have matched in the last seven days. Save it as report-only to watch first, and enable it when you have seen enough.

  • Report-only when you want to watch first
  • Schedules: weekdays 8 to 5, or overnight, applied by the device itself
  • Undo straight from the confirmation

Library

Categories, feeds and lists, defined once.

The building blocks profiles use. Look up which category a site falls in, add sites to a category or leave them out, and create your own. Choose which threat feeds devices match and whether each one alerts or blocks, and keep lists of countries and network owners for your policies.

  • Adult, gambling, social media, streaming, file sharing, AI services and more
  • Spamhaus, abuse.ch, FireHOL and Tor exit lists, refreshed automatically
  • Devices label names locally and never send the domain

Names, not just numbers

Every connection keeps its name.

Each device resolves its own names through ShadowLatch, so browsers stay on the system resolver and every connection keeps its name instead of hiding behind encrypted DNS. That is also where devices refuse known-bad and newly registered names before a connection starts. Send public names to Cloudflare, Quad9 or Google over encrypted DNS while internal names stay on your network, and refuse other encrypted-DNS services so nothing leaves unseen. Adapters return to their own DNS servers whenever the agent stops.

  • A block on a name or a category takes effect at the lookup, whatever program asked
  • Known bad and newly registered names refused per profile
  • Internal names never leave the network

Devices

Every device, its state, its seat.

Versions, groups, companies, the protected-data badge, the DNS resolver's state and intruder blocking at a glance. Build the installer with the options you want: group, company, tray icon, DNS resolver, server profile.

  • Change several devices at once: posture, profile, groups, updates
  • Installer options baked in, no command line
  • One-click updates, automatic by default

Intruders

Devices that defend themselves.

Any managed device that sees repeated failed logons or a port sweep blocks the address on the device within seconds. Blocks are temporary, grow longer when an address comes back, and every device in the account learns from each block. The exposure view shows what a device listens on, who connected inbound, and what it blocks right now.

  • Report-only first, then block mode; the account default, overridable per group or per device
  • Never-block list, pardons, account-wide reputation and an opt-in shared feed
  • Email and webhook alerts

Policies

Control the traffic that matters.

Block an application, a destination, a content category, everything a network owner announces, or a whole country. Decide who may reach a device (Remote Desktop, SSH, file sharing): ShadowLatch mirrors each inbound policy as a Windows Firewall rule and puts it back if anyone changes it. A policy is active as soon as devices pick it up. Not sure yet? Save it as Report only: devices record what it would have blocked, you check Review, then you switch it to Enabled. Apply it to one device, a group, a company or everyone, and remove it when it's no longer needed. Every change lands in the audit log.

  • Report only when you want to watch first; enable when you are sure
  • Application, destination, category, owner (ASN) and country policies; inbound policies with Windows Firewall
  • Content categories (social media, streaming, file sharing, adult): devices label names locally and never send the domain
  • Threat-intelligence feeds (abuse.ch, Spamhaus DROP, FireHOL, Tor exits and more): alert-only or block, per feed
  • Protocol controls: turn off QUIC, IPv6 or IPv4 as the account default, per group or per device; ShadowLatch's own traffic and the basics a device needs stay allowed, so a policy can never strand a managed device
  • Scheduled policies: permanent by default, or weekdays 8 to 5 and overnight, applied by the device itself
  • Local-network privacy: hide a device from discovery and ping on the network it is on, and use a random Wi-Fi hardware address per network; the account sets the default, a group or a device can override it
  • Device postures: Managed, Paused for an hour or a day, Quarantine, or Lockdown (only what an Allow policy permits gets through)
  • Device, group, company or fleet-wide scope; policy folders shared by several profiles

Where it fits

Built to sit beside what you already run.

Works alongside your antivirus and EDR

ShadowLatch is the network layer. It shows and controls what applications connect to, and leaves file scanning and threat hunting to the tools you already run.

Sees connections, not content

It records which program reached which address, port and name, and when. It never captures packets or opens HTTPS traffic, so it's safe to run where privacy matters.

Reports what the device observed

An allowed connection means the device tried and was permitted; a blocked one means ShadowLatch stopped it. Counts are observations, which is exactly what an investigation needs.

History as long as your plan keeps it

Every page searches the full retained window, 30 days to six months depending on plan (longer on request). Choose the length that matches how far back your team looks.

See it on your own devices.

The closed beta begins on November 1, 2026.
