Services

Brasstower provides advisory across six practice areas. Each scales up or down within the retainer based on the client's needs and roadmap priorities. The work is both leadership-driven — designed to align to the client's revenue and business objectives — and technical: hands-on deliverables including code, prototypes, architecture reviews, threat models, policy design, and written documentation.

Practice Area 01
Executive Advisory & Due Diligence
Security strategy, risk communication, and board-level advisory. Due diligence for M&A, investment, and partnership decisions — assessing target company security posture, identifying material risks, and producing actionable findings.
  • Quarterly risk briefings and board decks
  • Investor-facing security narratives
  • M&A and investment security due diligence
  • Security program maturity assessments
Practice Area 02
AI & Agentic Security
Security architecture for AI/ML systems, agentic workflows, model deployment pipelines, and tool-chain authorization. Covers the full lifecycle from training data integrity through inference-time controls to multi-agent coordination security.
  • Agentic architecture threat modeling
  • Tool-chain authorization and policy design
  • Model deployment pipeline security review
  • AI compliance and governance frameworks
Practice Area 03
Product Security & Architecture
Design reviews, architecture assessments, and threat modeling for production systems. Embedded in the engineering workflow — reviewing PRs, participating in design discussions, and producing written threat models for new features, services, and infrastructure changes.
  • Architecture and design reviews
  • Threat modeling for new capabilities
  • Secure development lifecycle integration
  • Infrastructure and cloud security review
Practice Area 04
Cryptologic Services + Identity & Authentication
Cryptographic protocol design and review, key management architecture, attestation systems, and identity infrastructure. Covers both the selection and implementation of cryptographic primitives and the authentication systems built on top of them.
  • Cryptographic protocol review and design
  • Key management and HSM architecture
  • Authentication and identity system design
  • Attestation and hardware root-of-trust
Practice Area 05
Standards & Governance
Compliance program design, gap assessments, and audit preparation across SOC 2, HIPAA, PCI-DSS, GDPR, and emerging AI-specific frameworks. Focused on building programs that satisfy auditors without creating bureaucratic overhead that slows engineering.
  • SOC 2, HIPAA, PCI-DSS, GDPR compliance
  • AI governance and ISO 27090/91 alignment
  • Policy design and documentation
  • Audit preparation and remediation
Practice Area 06
R&D & Security Product Development
Novel security research, prototyping, and product development for problems where off-the-shelf solutions don't exist. From concept through working prototype — code, architecture, and documentation delivered as client-owned IP.
  • Novel security tooling and prototype development
  • Research into emerging threat classes
  • Custom security feature design and implementation
  • Patent-ready architecture and documentation
