Why Ransomware

Ransomware attacks have become the most disruptive cyber threat. Organizations that test their defenses recover faster and reduce impact when attacked.

The Challenge

Ransomware Readiness Challenges Organizations Face

Most organizations believe they're prepared for ransomware—until an attack proves otherwise. These challenges leave you vulnerable.

Untested Detection

You've deployed EDR, SIEM, and security tools, but have you verified they actually detect ransomware behaviors? Most organizations haven't.

Detection

Slow Response Times

Ransomware can encrypt thousands of files per minute. If your team takes hours to respond, the damage is already done.

Response

Unverified Backups

Backups exist, but can you actually restore from them? Many organizations discover backup failures during the worst possible moment.

Recovery

Paper Plans

Your incident response plan looks great on paper, but has it ever been tested under pressure? Untested plans fail when you need them most.

Planning

Team Readiness

When ransomware strikes, does your team know exactly what to do? Panic and confusion cost precious time and make bad decisions worse.

People

Regulatory Pressure

NIS2, DORA, and cyber insurance all demand proof of ransomware resilience. "We think we're ready" isn't evidence.

Compliance

Unknown Attack Surface

Where would ransomware spread in your network? Understanding lateral movement paths is critical but rarely mapped.

Architecture

Privilege Escalation Gaps

Ransomware operators seek domain admin. Can they get it in your environment? Most organizations don't know.

Access Control

Security Control Bypass

Modern ransomware includes techniques to disable security tools. Are your controls resilient against tampering?

Evasion

Common Questions

Frequently asked questions

Absolutely safe. We simulate ransomware behaviors without actual encryption. Our tools execute the same techniques real ransomware uses—file enumeration, lateral movement, privilege escalation—but stop before any destructive action. You get the detection validation without the damage.
Yes, with appropriate safeguards. We can conduct simulations in production, staging, or dedicated test environments depending on your risk tolerance. Production testing provides the most realistic results, but we establish strict safety boundaries and can pause or abort at any time.
We simulate techniques used by major ransomware groups including LockBit, BlackCat/ALPHV, Royal, Cl0p, and others. We select techniques based on threat intelligence about which groups target your industry, ensuring relevance to your actual threat landscape.
Penetration testing focuses on finding vulnerabilities. Ransomware simulation focuses on detection and response validation. We assume initial access and test whether your security stack detects ransomware behaviors, whether your team responds effectively, and whether you can recover.
That's exactly what we're testing for! Finding detection gaps in a controlled simulation is far better than discovering them during a real attack. We provide specific recommendations and detection rules to close the gaps we identify.
Yes, we can integrate IR plan testing into the simulation. You can choose whether your team knows when the simulation will occur (announced) or run it unannounced to test real-world response. Either approach provides valuable insights.
Technical simulations typically run 3-5 days of active testing, plus planning and reporting time. Tabletop exercises are 2-4 hours. Full ransomware readiness assessments take 2-3 weeks. We can scope engagements to match your timeline and objectives.
Depends on simulation type. For detection validation, we need endpoints with your security tools installed. For full simulation, we may need network access similar to an attacker post-compromise. We work with you to define appropriate access levels.
Absolutely. Many cyber insurers now require evidence of ransomware resilience testing. Our reports document your detection capabilities, response procedures, and backup validation—exactly what insurers want to see.
We can start with a Ransomware Readiness Assessment to evaluate your current state before running simulations. This gives you a baseline and prioritized improvements. You don't need to be mature to start—you need to start to become mature.

"We thought we were ready for ransomware—EDR deployed, backups in place, IR plan documented. The simulation revealed our EDR only caught 40% of the techniques, our backup restoration took 3x longer than expected, and our team didn't know the escalation path. Six months later, we tested again and scored 85%. When we were actually attacked, we contained it in 4 hours."
