The ransomware simulation platform built for defenders
Runstrike safely emulates real ransomware behavior against your environment — encryption, ransom notes, and impact — so you can prove your defenses work before attackers test them for you.
How Runstrike compares
| Capability | Runstrike | Cobalt Strike | BAS Platforms* |

| Custom binary generation | Yes | No | No |
| Sandbox-verified payloads | Yes | No | No |
| Safe simulation mode | Yes | No — always live | Yes |
| Policy-gated live execution | Yes | Unrestricted | Limited |
| Forensic artifact detection | Built-in forensic agent | No | EDR-dependent |
| Real-time monitoring | Yes | Yes | Yes |
| Onboard in minutes | Register one agent | Manual setup | Cloud integration |

What sets us apart
Ransomware-agnostic
Not tied to one strain or playbook. Emulate the behavior of any ransomware family — encryption patterns, ransom notes, and impact — without writing a single exploit.
Custom binary generation
Generate purpose-built simulation payloads on demand, then verify them in an isolated sandbox before anything touches your environment.
Safe by default
Start in simulation mode where actions are logged, not executed. Promote to policy-gated live runs only when you choose to.
Forensic verification
A built-in forensic agent hunts the artifacts ransomware leaves behind — encrypted files, dropped ransom notes, deleted shadow copies, persistence. Measure real impact, not just whether a command ran.
Zero infrastructure
Nothing to stand up or maintain. Register a lightweight agent on the machines you want to test and you're running simulations in minutes — we run the platform.
