FEDERAL & NATIONAL SECURITY

Validate mission systems against nation-state tradecraft, continuously, at machine speed.

SIEGE runs as a persistent adversary against federal and national-security environments, built under the DARPA CASTLE program and operationally refined across DoD and U.S. Government programs. It automates red-team operations, validates mission systems, and produces continuous, RMF-aligned evidence for authorizing officials across classified and unclassified networks.

THE ATTACK PATH

This is how the breach actually happens.

FIG.01: ADVERSARY PATH / FEDERALAGENT ACTIVE

From initial access to a mission system. SIEGE emulates nation-state campaigns end-to-end so authorizing officials see real risk, not a checklist.

THE THREAT

Who's actually coming for you.

Federal mission systems face the most capable adversaries in the world, foreign intelligence services with patience, budget, and intent. SIEGE emulates their campaigns as documented in U.S. Government and allied advisories.

APT29 · SVR

Stealthy Espionage Campaigns

Russian SVR-linked actors run patient, low-and-slow intrusions against government networks. SIEGE replays their tradecraft to validate detection deep in the kill chain.

Volt Typhoon · PRC

Critical-Infrastructure Pre-Positioning

PRC state actors embed in networks using living-off-the-land techniques to enable future disruption. SIEGE pressure-tests whether your controls surface this stealthy activity.

Insider · T1078

Insider & Credential Abuse

Valid credentials are the most reliable way into a hardened network. SIEGE validates least-privilege, segmentation, and zero-trust enforcement against credentialed adversaries.

THE MANDATE

FISMA and RMF ask for proof. SIEGE delivers it continuously.

Federal authorization frameworks all ask whether security controls are effective, not just documented. SIEGE produces continuous, control-level evidence that supports RMF authorization and the move toward continuous ATO.

Mandate	Requirement	SIEGE Evidence
FISMA	Effective agency information-security program	Continuous, control-level effectiveness evidence
NIST SP 800-37 (RMF)	Assess & authorize / continuous monitoring	Ongoing adversarial assessment supporting cATO
NIST SP 800-53	Security & privacy control baselines	Exploit-ranked validation per control family
DoD Zero Trust	Target-level zero-trust activities	Adversarial validation of ZT enforcement points
FedRAMP	Cloud service security authorization	Continuous validation of cloud control effectiveness

THE PROOF

Built under DARPA. Validated by DoD.

SIEGE was built under the DARPA CASTLE program and operationally validated across DoD and U.S. Government environments, its agents trained by practitioners with deep cyber-operations pedigree and decades of real cyber-operations experience. For authorizing officials and program offices, SIEGE speaks the language you already use, and proves resilience to the standard your mission demands.

THE MATH

Why continuous beats point-in-time.

Continuous ATO

SIEGE supports the shift from annual assessments to continuous authorization with always-current control evidence.

FY2027

DoD's target for achieving its Zero Trust goals. SIEGE validates ZT enforcement on the way there.

Machine speed

AI agents run red-team operations continuously, covering ground a human team can't match.

FREQUENTLY ASKED

Questions teams ask before a SIEGE engagement.

How does SIEGE support FISMA and the NIST Risk Management Framework (RMF)?

SIEGE continuously assesses the effectiveness of security controls and maps results to NIST SP 800-53 control families and the RMF lifecycle. This control-level, always-current evidence supports authorization decisions and the federal shift toward continuous Authorization to Operate (cATO).

Is SIEGE suitable for classified or air-gapped environments?

Yes. SIEGE is built on a modular, containerized architecture that deploys on-premises, including in isolated and classified enclaves, and was operationally refined across DoD and U.S. Government environments.

What is SIEGE's pedigree for national-security work?

SIEGE was developed under the DARPA CASTLE program, a rigorous adversarial-AI research program, and its agents were trained by practitioners with deep cyber-operations pedigree and decades of real-world cyber-operations experience. That provenance is validated, not marketed.

How does SIEGE automate red teaming?

SIEGE's AI agents autonomously plan and execute adversary campaigns end-to-end: initial access, lateral movement, privilege escalation, and impact, adapting like a real attacker. This lets a small team continuously exercise mission systems at machine speed instead of waiting for periodic manual assessments.
