Public Sector

Secure by design, the way the mandates now expect.

Government directives increasingly ask agencies and their vendors to design security in and to show their work. ThreatModeler^® Nexus™ captures the intended design as a model and produces the evidence behind it, so meeting a secure-design mandate becomes a repeatable practice instead of a documentation drill.

Designed in, documented, and ready when asked.

The public-sector reality

Mandates to meet, legacy to modernize, and scrutiny throughout.

Agencies carry decades of systems while modernizing under directives that expect security by design and the evidence to prove it. The work has to be defensible and consistent, across new builds and systems already in service.

"The directive says design security in. In practice, we're assembling that evidence after the fact for every system."

Make secure design a model. The System Mapping Agent captures the intended design from artifacts or from the code, so secure design is recorded work, and the Reporting Agent turns it into the documentation a review expects.

"We're modernizing systems that have run for years and have no current threat model at all."

Start from what's running. The System Mapping Agent infers the design from existing systems, and the Secure Design Graph grounds it in real context, so a legacy system gets a current model as modernization begins.

"Every program documents differently, so nothing lines up when oversight comes asking."

Standardize the practice. Prebuilt templates and approved content give every program the same secure starting point, so evidence is consistent across the agency instead of program by program.

Defensible by construction

Meet the mandate, and prove you met it.

ThreatModeler Nexus is a threat modeling platform first: it shows what could go wrong in a system so you can design the risk out. The agents do the mechanical work and produce the evidence, so compliance follows from the design rather than a separate effort.

By design

Intent on the record

The intended design becomes a model built from artifacts or inferred from code, so secure design is documented and repeatable across programs.

Traceable

Evidence on demand

Every threat, control, and decision traces to the architecture and the framework it satisfies, with timestamps and version history that survive turnover.

Governed

Accountable AI

Role-based access, approval workflows, and a deterministic framework keep people accountable for decisions while the AI accelerates the work.

Mandates and directives

The directives that require threat modeling by name.

Federal agencies and their suppliers now face explicit requirements to adopt secure software development practices, and threat modeling is named in the standards that underpin them. ThreatModeler Nexus operationalizes compliance with these mandates at the design level: so the evidence is produced as the work is done, not reconstructed when oversight arrives.

Regulation & Compliance

✓

Executive Order 14028 (May 2021). Required federal agencies to adopt zero-trust architecture, secure development practices, and supply chain transparency. ThreatModeler Nexus implements the threat modeling component of secure software development required by EO 14028.

✓

NIST SSDF 1.1 (SP 800-218). Control PW.1.1 explicitly requires threat modeling as part of a secure development process. The OMB memo (May 2022) requires federal software suppliers to demonstrate compliance with SSDF.

✓

FedRAMP. Cloud service providers seeking FedRAMP authorization must demonstrate continuous risk assessment. The Secure Design Graph provides the application-level risk record FedRAMP requires.

✓

NIST CSF 2.0. The updated Cybersecurity Framework explicitly includes identify-function activities that threat modeling addresses, including business environment, risk assessment, and risk management strategy.

✓

FISMA and DISA STIGs. Federal Information Security Modernization Act requirements and Defense Information Systems Agency security technical implementation guides, mapped to controls and findings in the Secure Design Graph.
