Inside Our Virtual SCIF: Sophos Intercept X vs. Ransomware

USMC/NSA-honed tradecraft applied to a software-defined SCIF with Sophos Intercept X—keeping high-profile investigations uncompromised.

How we turned Sophos into a “virtual SCIF”

Sensitive investigations can’t afford ransomware, data leakage, or even a single compromised laptop. To protect federal agents and partner investigators, we engineered a virtual SCIF (a software-defined secure compartmented information facility) using Sophos Intercept X and Sophos Central as the control plane. Practically, that meant zero-trust workstation builds, hard application allowlists, deep anti-exploit controls, CryptoGuard anti-ransomware, device isolation on demand, and airtight identity/RBAC across enclaves.

The core: Sophos Intercept X Anti-Ransomware

• CryptoGuard detects and rolls back malicious encryption attempts in real time.
• Exploit prevention blocks the techniques attackers use before malware lands.
• XDR/MDR elevates visibility and 24×7 response when a human-on-the-loop matters.
• Application Lockdown and Malicious Traffic Detection disrupt “living off the land” pivots.

The architecture (pattern we deploy)

• Enclave workstations: clean images, device encryption, no local admin, phishing-resistant MFA.
• Network micro-segmentation: dedicated VLANs, least-privilege egress, outbound intel/DNS controls.
• Content controls: DLP policies, blocked removable media, signed-artifact publishing only.
• Golden path for evidence: sealed shares with write-once workflows and tamper-evident logging.
• Rapid isolation: one-click host quarantine from Sophos Central; auto-ticket + IR playbooks.
• Forensics-friendly: timeline, root-cause graphs, and artifact capture without polluting evidence.

Case impact

Using this virtual SCIF approach, our teams helped investigative partners operate securely while pursuing major corruption and medical fraud probes in California. We can't reveal operational details, but the public record includes the arrest and later conviction of a California state senator on federal charges, as well as the multi-year “Billion-Dollar Back Surgery” healthcare scheme (Operation Spinal Cap) that produced numerous convictions. Our role: keep endpoints, identity, and data flow uncompromised so investigators could move fast without fear of ransomware, insider sabotage, or external nation-state interference.

Results you can measure

• Zero ransomware incidents inside the enclave across the engagement.
• Minutes-to-isolation MTTC for suspicious hosts via Sophos Central.
• Fewer false positives thanks to exploit-centric blocking and CryptoGuard rollback safety net.
• Repeatable blueprint now adapted for high-risk teams worldwide (public sector & regulated industries).
