HEALTHCARE

Validate the path to PHI is closed, before an investigator asks.

SIEGE runs as a persistent adversary against your environment, emulating the ransomware and data-extortion crews that have made healthcare the most-breached industry in the country. It validates network segmentation, access controls, and lateral movement to PHI, and generates HIPAA- and HHS 405(d)-aligned evidence mapped to MITRE ATT&CK.

THE ATTACK PATH

This is how the breach actually happens.

FIG.01: ADVERSARY PATH / HEALTHCAREAGENT ACTIVE

From a single phished credential to the EHR. SIEGE finds the route to PHI before ransomware does.

THE THREAT

Who's actually coming for you.

Healthcare is the most-targeted industry for ransomware. SIEGE emulates how these actors actually operate, as documented by CISA and HHS HC3.

ALPHV / BlackCat

Healthcare Ransomware Crews

CISA and HHS have issued repeated advisories on ransomware groups specifically targeting hospitals and health systems. SIEGE replays their phishing-to-encryption playbook against your controls.

T1486 · Extortion

Double-Extortion of PHI

Modern operators exfiltrate PHI before encrypting, then extort on both. SIEGE validates the exfiltration and lateral-movement paths to your records, where you can still stop them.

T1190 · Third-Party

Vendor & Device Footholds

Unmanaged medical devices and third-party connections are common entry points. SIEGE extends validation into the segments where asset visibility ends.

THE MANDATE

Every requirement asks if your controls work. SIEGE proves it.

Each requirement below asks whether your controls actually hold. SIEGE produces the evidence one time and maps it to every framework your auditors use.

Mandate	Requirement	SIEGE Evidence
HIPAA §164.308(a)(8)	Technical evaluation of safeguards	Continuous technical evaluation with dated evidence
HIPAA §164.308(a)(1)	Risk analysis	Real attack-path risk ranked by exploitability
HHS 405(d) HICP	Recognized security practices	Validation that HICP controls hold under attack
NIST CSF 2.0	Protect / Detect outcomes	Mapped control validation across the framework
OCR investigation	Evidence of reasonable diligence	Pre-incident proof of segmentation to PHI

THE PROOF

Built under DARPA. Validated by DoD.

When SIEGE confirms the path to PHI is closed, that finding carries the weight of the DARPA CASTLE program and validation across DoD and U.S. Government environments. For your board, your auditors, and the patients who trust you with their records, it is proof your safeguards hold, not a checkbox.

THE MATH

Why waiting is the expensive option.

$10.93M

Average healthcare data breach cost, the highest of any industry for 14 consecutive years.

Healthcare is the most-targeted sector for ransomware, per CISA and HHS reporting.

Pre-incident

SIEGE produces OCR-ready evidence of diligence before an investigator ever asks.

FREQUENTLY ASKED

Questions teams ask before a SIEGE engagement.

How does SIEGE support HIPAA Security Rule compliance?

SIEGE validates the technical safeguards behind the HIPAA Security Rule, segmentation, access controls, and the path to electronic protected health information (ePHI), and produces dated evidence of a technical evaluation (§164.308(a)(8)) and risk analysis (§164.308(a)(1)) mapped to real attack paths.

What is HHS 405(d) HICP and how does SIEGE help?

HHS 405(d) Health Industry Cybersecurity Practices (HICP) are recognized security practices for healthcare. SIEGE validates that those practices actually hold under attack, giving you evidence that recognized practices are not just documented but effective.

Will SIEGE disrupt clinical systems or EHR access?

No. SIEGE runs in simulated or mirrored environments and never touches production systems, so clinical care and EHR availability are never affected.

How does SIEGE help if the Office for Civil Rights (OCR) investigates?

SIEGE produces pre-incident evidence of segmentation and reasonable diligence toward PHI, dated, attack-path-based proof you can present to demonstrate your safeguards were tested and effective before any investigation.
