Instant CSIRT simulations

Train your incident response team in hours, not months

Launch a realistic DeepDive scenario, based on sector-relevant threat intelligence, whenever you need one. Built to challenge your leaders as much as your responders, it ends with an audit-ready report and a clear plan to strengthen your response.

Live, branching incident simulation

DeepDive attack map with the Leeds operations centre compromised, inbound traffic converging on it from across Europe, and a decision path branching to refuse contact

Fine-tuned simulation control

Facilitator console with the inject timeline, severity, incident stage and running regulatory clocks

Realistic live injects

A cascade of incoming injects: a critical security alert, SMS, voicemail, news story, emails and chat messages

Deep, audit-ready insights

Simulation report with a response score of 78, NIST incident response phase scores, HSEEP capability ratings and key moments
  1. Launch in seconds

    Choose a prebuilt scenario, such as ransomware, supply chain attacks or web defacement, and start instantly. Or, work with us to build you something custom.

  2. Scenarios that bite

    Branching injects that react to your team’s decisions, built by the same experts who run our pentests. Designed to expose gaps in your response, and help you fix them.

  3. Audit-ready feedback

    Every run is scored on a framework built on NIST, HSEEP and SIM3 guidelines, with actionable feedback and a tailored improvement strategy.

Our guarantee

Measurable improvement, guaranteed

Run DeepDive for 90 days and put our feedback into practice. If your team’s response scores haven’t improved from your first simulation, we’ll give you a year of access free.

  1. Preparation

    We evaluate your incident response plan, playbooks, and team preparation before a simulation even begins.

  2. Detection & Analysis

    Get a read on your team’s ability to investigate an incident, and their capacity to understand the root cause of cybersecurity breaches.

  3. Containment, Eradication & Recovery

    Develop and assess your organisation’s ability to apply practical incident response measures to close an incident.

  4. Post-Incident Activity

    Assess your incident management, team communication, and ability to apply feedback to improve your response.

Continuous pentesting

Continuous pentesting, with experts in your corner

DeepDive turns pentesting from a shallow, one-off snapshot into a continuous process with free retesting. Security that works with your business, not against it.

  1. Pentests, not PDFs

    Continuous testing that grows with your business, plus a live dashboard and tracking support to help your team close its backlog.

  2. Direct line to an expert

    Get direct support from OSCP-certified professionals, with no barrier between you and the expertise.

  3. Remediation support

    We help you fix what we find, then retest for free to confirm it’s closed, so findings don’t sit until next year’s audit.

The stakes

Data breaches can sink your business

The impact of a breach goes far beyond data compromise. It can grind your operations to a halt. But the real loss is much harder to reverse: damaged customer trust, regulatory fines and a reputation that takes years to rebuild.
