Ransomware readiness simulation
Find out what your ransomware defences detect, what they miss, and what to improve next. A controlled, isolated assessment of how your endpoint detection, logging, alerting and investigation respond to ransomware activity. It is validated with your defensive team and mapped to MITRE ATT&CK
Challenges we solve
Move from confidence in your tooling to evidence of how your detection and response work together.
Unclear ransomware remediation priorities
Give technical teams and decision-makers the same evidence, with risk-linked recommendations that focus effort where it matters most.
Gaps between alerts and action
A detection is only useful if your analysts can investigate it. Find missing telemetry, weak correlation, and unclear triage before an incident tests them.
Unproven ransomware defences
Your security tools are in place. You still need evidence that they recognise ransomware behaviour on a build that reflects your own endpoints.
Ransomware testing without production disruption
Evaluate selected live ransomware samples in an isolated copy of your standard build, rather than encrypting production systems.
What is ransomware readiness simulation?
Claranet’s Ransomware Readiness Simulation is a controlled technical assessment of your ability to detect, investigate, and respond to ransomware activity. We execute selected live ransomware samples and behaviour-based techniques against a copy of your standard gold-build image (the approved endpoint build you deploy across your estate) inside an isolated environment, not your production estate.
Working in a purple team model, where offensive and defensive specialists work together on the same exercise, our offensive specialists collaborate with your defensive team to validate detection, alerting, and response across the agreed ransomware scenarios. Each executed technique is mapped to the MITRE ATT&CK framework, it is a widely used knowledge base of adversary tactics and techniques. Mapping each executed technique to it gives your technical and security teams a common reference for what was tested and what was observed.
You receive evidence for technical decisions and a clear account of business risk: an executive summary, technical findings, a detection-and-response matrix, and a prioritised improvement roadmap. The result is a practical plan for strengthening your ransomware readiness, not a guarantee that every attack will be detected.

What’s included
Connect the attack behaviour, the security signal, and the action your team can take.
Sector-aligned ransomware threat modelling.
We research the ransomware groups and malware families relevant to your sector, document the simulation plan, and map the selected tradecraft to MITRE ATT&CK before execution, so the scenarios are agreed and relevant before anything runs.
Controlled, isolated execution
Selected live ransomware samples and behaviour-based techniques run against a copy of your standard gold-build image. Execution uses agreed windows and safety checks in a segregated sandbox, so you see how your tooling responds without encrypting production systems.
Collaborative purple team validation
Our offensive specialists work alongside your defensive team to observe alerts, severity classification, telemetry, and triage as techniques execute. Visibility gaps become a practical discussion, not a surprise in the report.
MITRE ATT&CK coverage mapping
Every executed technique is mapped to its tactic and technique identifier, then recorded as detected, partially detected, or not detected. The result is a clear view of tested coverage: where it holds and where it needs attention.
Detection and response gap analysis
We assess endpoint detection, log coverage, alert quality, event correlation, investigation, and containment readiness, so you can see where telemetry, correlation or triage need work. Where the data is available, we capture time to detect and time to investigate.
Reporting and an improvement roadmap
You receive a consolidated report with an executive summary and detection maturity rating, technical findings, a detection-and-response matrix, and a prioritised 30/60/90-day improvement roadmap. A senior colleague reviews the report before release.
Optional extensions and scope limits
Optional extensions. A defensive detection workshop, additional ransomware family coverage, recurring simulations, and a findings debrief are available as separately charged options.
Scope and limitations. This is a point-in-time assessment of the agreed techniques and test configuration. It is not a production encryption exercise, backup recovery test, or ongoing monitoring service. A strong result does not guarantee that every future attack will be detected.
Accreditations and partnerships
Part of Claranet's wider cybersecurity practice. These organisational credentials are not a certification of the assessment result.

Ransomware readiness simulation: frequently asked questions
-
No. Selected live ransomware samples and behaviour-based techniques run against a copy of your standard gold-build image in an isolated environment, separate from your production estate. It is not a production encryption exercise.
-
A ransomware readiness simulation is designed for organisations that already have security tools in place and need evidence of how well they detect and respond to ransomware behaviour on their own endpoint build. It supports:
- Security and technical teams who want to find missing telemetry, weak correlation and unclear triage before a real incident does.
- Decision-makers who need risk-linked recommendations and a prioritised plan that focuses effort where it matters most.
- Organisations that cannot disrupt production, because the testing runs on an isolated copy of the standard build rather than encrypting production systems.
-
No. It is a point-in-time assessment of the agreed techniques and test configuration. It is not a backup recovery test or an ongoing monitoring service.
-
No. The simulation shows what your defences detected, partially detected and did not detect for the agreed techniques and test configuration. It is not a guarantee that every attack will be detected.
-
A gold-build image is the standard, approved endpoint build an organisation uses as the basis for its devices. The simulation runs against a copy of yours, so the results reflect how your own build and tooling behave.
