What this actually is

Sometimes the answer is not another assessment, it is building the thing properly. A new office, a data centre migration, a cloud landing zone, or an estate that has never had a coherent design.

We design and implement the corporate security architecture end to end. Segmentation, identity, endpoint, email, remote access and monitoring, built as a system rather than as seven products bought at different times.

Then we document it, so the next person to touch it understands why it looks the way it does.

What we go after

  • Security architecture design and review
  • Network segmentation and zero-trust access
  • Identity and access management implementation
  • Endpoint and mobile device management rollout
  • Email security and anti-phishing controls
  • Remote access and VPN replacement
  • Backup and recovery architecture
  • Monitoring and logging design

How we run it

  1. 01

    Onboard

    Log sources, agents and integrations connected, with a baseline of what normal looks like for you.

  2. 02

    Tune

    Detection rules written for your environment. We would rather spend two weeks tuning than send you noise for a year.

  3. 03

    Monitor

    Round the clock triage with severity-based response times, including nights and weekends.

  4. 04

    Respond

    Playbook-driven containment with approval gates on anything that touches production.

  5. 05

    Report and improve

    Monthly reporting your board understands, and detection coverage that grows every quarter.

What you receive

  • Target architecture with design rationale
  • Phased implementation plan
  • Build and configuration documentation
  • Operational runbooks and handover
  • Post-implementation validation testing

Who needs this

Organisations building or rebuilding infrastructure, opening new sites, or consolidating after an acquisition.

How long it takes

Six weeks to six months depending on scale.

Standards this satisfies

  • ISO 27001
  • CIS Controls
  • NIST CSF
  • Zero Trust principles

Why it matters

Detection is not a product you buy, it is a capability you operate. Most organisations that have bought the tooling still do not have the capability, because coverage thins overnight and at weekends, which is precisely when intrusions begin.

Dwell time is the single largest driver of what a breach costs. Everything managed defence does is aimed at that one number: seeing it sooner, understanding it faster, and containing it before it becomes a recovery exercise.

Choose how you want this delivered

Most of the price difference between quotes comes down to this one choice, and it is rarely explained. Pick one to see what it covers, what it suits and what it costs you.

We take monitoring, triage, investigation and first response, around the clock, with a named service lead who knows your environment. Escalation reaches a person with context rather than a queue, which is the difference that matters at three in the morning.

Choose this when

  • No internal security operations capability
  • Regulatory expectation of continuous monitoring
  • You want one accountable party for detection and response

Effort and cost

Monthly, scaled by estate size and log volume. Predictable, which is usually the point.

Scope it yourself, before you call anyone

Answer a few questions and you get an indicative number, the working behind it and what your answers tell us. It runs in your browser, so nothing you type reaches us.

What we look for, and keep finding

These are the classes of problem this work exists to surface. Not every engagement finds all of them, but these are the ones that turn up often enough to be worth naming.

  • Exposed management interfaces

    Administrative panels, database ports and remote access services reachable from places they should not be. Usually the result of a firewall rule added for a project and never removed.

  • Weak and reused credentials

    Default passwords still in place, service accounts sharing a password across systems, and credentials that survive in scripts and scheduled tasks long after the person who wrote them left.

  • Missing patches on reachable services

    We prioritise by what is actually reachable and actually exploitable rather than by scanner severity, because a critical on an unreachable host matters less than a medium on your perimeter.

  • Flat internal networks

    Once inside, an attacker can reach everything. We test lateral movement explicitly: from a compromised workstation, what can we get to, and how long does it take.

  • Active Directory weaknesses

    Kerberoastable accounts, unconstrained delegation, excessive privilege and stale administrative groups. Domain escalation is usually a chain of small misconfigurations rather than one flaw.

Who runs your engagement

A named service lead and a real team behind them

You get a named lead who knows your environment, backed by an analyst team running around the clock. Escalation reaches a person who has context rather than a queue, which is the difference that matters at three in the morning.

Questions we get asked

Do you resell the hardware and licences?

We can, through our OEM partners, and we will be transparent about margin. If buying direct is better for you we will say so.
