Ransomware Is a Business-Critical Risk

Ransomware incidents today involve lateral movement, data exfiltration, and prolonged operational downtime - not just file encryption.

A significant portion of modern incident-response engagements across enterprises involve ransomware-driven breaches.

Real-world ransomware recovery costs frequently reach multi-million-dollar impact when accounting for downtime, response, legal, and recovery efforts.

Cyber insurers, boards, and regulators now explicitly ask:

"Do you test ransomware detection and recovery?"

Simulation and preparedness are no longer optional. Organizations either test ransomware readiness on their own terms - or attackers will do it for them.

Impact varies by industry, scope, and environment. Sources available on request.

Ransomware Readiness Can't Be a Checkbox

Traditional controls such as endpoint protection, backups, and firewalls remain necessary - but they are no longer sufficient on their own.

Today's Reality

  • •Attackers rehearse: automated playbooks, tested tooling, and repeatable campaigns
  • •Defenders often don't: many organizations have never exercised a full ransomware scenario end-to-end
  • •Insurers are tightening requirements: evidence of tested backups, recovery plans, and response workflows is increasingly mandatory

The Gap

This gap between policy and practice is where ransomware causes the most damage. Organizations need a way to safely test their ransomware readiness without risking production systems.

What Good Looks Like

  • •Proven detection coverage across the kill chain
  • •Measured response timelines and playbook outcomes
  • •Recovery validation (RTO/RPO evidence)

Introducing SecGrid RSX™

SecGrid RSX™ (Ransomware Simulation eXperience) is a high-performance, enterprise-grade ransomware simulation framework, built in Go, designed to help organizations safely experience a ransomware attack in controlled environments - before a real one occurs.

RSX™ enables security teams to simulate the full ransomware kill chain, from initial access to encryption impact and recovery validation, without risking production systems or real business data.

CRITICAL WARNING (Intentional & Explicit)

NEVER: Run in production environments

ALWAYS: Execute inside isolated virtual machines or lab environments

Restricted Real Mode: Performs actual operations, including file encryption and system modification

Governance: RSX™ is governed by technical safeguards, policy controls, and contractual restrictions to prevent misuse

Designed for authorized defensive security testing only.

RSX™ Is

  • • A controlled ransomware adversary-simulation framework
  • • A platform to validate detection, response, and recovery in real conditions
  • • A way to rehearse ransomware "fire drills" with SOC, IR, and IT teams

RSX™ Is Not

  • • Not ransomware, not a builder, not intended for production
  • • Not commodity malware or a crimeware builder
  • • Not licensed or designed for production use
  • • Not a generic breach-and-attack simulation (BAS) tool

How SecGrid RSX™ Works

1

Step 1 — Plan

Define scope, select ransomware scenarios, validate lab controls, and align execution with organizational security policies.

Includes scenario selection, environment validation, and policy alignment.

2

Step 2 — Execute

Safely simulate ransomware behavior using simulation-first execution, with optional Restricted Real Mode in hardened environments.

Controlled execution with real-time monitoring and safety guardrails.

3

Step 3 — Report

Generate actionable findings covering detection gaps, response timelines, recovery readiness, and governance evidence.

Executive and technical reports with actionable remediation guidance.
