Part 1. Purpose & Positioning

The Cybersecurity Advisory service provides a high-touch security architecture program that embeds a single, dedicated security expert early in the development process. The engagement keeps delivery aligned to pre-defined security milestones and measurably reduces exploitation risks across smart contracts, web applications, decentralized applications, layer-1/layer-2 components, and supporting infrastructure.

Expected Outcomes

Organizations engaging Hacken's Cybersecurity Advisory service receive comprehensive security support throughout their software development lifecycle:

During Development:

• Embedded Security Expertise — Dedicated security architect integrated into your development workflow, providing real-time guidance and threat modeling.
• Defined Security Objectives — Clear success criteria, risk thresholds, and security milestones aligned with your project roadmap.
• Continuous Risk Assessment — Ongoing identification and documentation of threats, attack surfaces, and vulnerabilities as your architecture evolves.

Pre-Deployment:

• Mitigation Strategy Development — Concrete, prioritized security controls and remediation plans tailored to identified risks.
• Audit Readiness Support — Guidance on documentation, code preparation, and scope definition to streamline formal security assessments.
• Audit Process Ownership — During formal security assessments, manages day-to-day execution, tracks findings resolution, and owns regression testing and remediation verification to closure.

Post-Deployment:

• Operational Security Continuity — Advisory support for secure upgrade procedures, governance controls, and change management.
• Incident Response Preparedness — Documented response playbooks, escalation procedures, and periodic incident simulation exercises.

Built for Mid-Stage Teams Shipping at Scale

This service is designed for protocol teams, financial institutions, exchanges, wallets, L1/L2 foundations, and Web2/Web2.5/Web3 product companies that require security to advance in parallel with delivery—not act as a bottleneck.

Your team will benefit from this approach if:

• Security-by-design is a priority — Your team wants to identify and address risk during active development, not after code is finalized.
• You need embedded, iterative security controls implemented — Security validation must align with sprints, milestones, and deliverable ownership rather than one-time assessments.
• You require objective, third-party expertise — Your internal security posture needs independent validation free from organizational bias or delivery pressure.

Part 2. Service Model: Single Dedicated Advisor, Flexible Capacity Tiers

Each engagement assigns at least one embedded cybersecurity advisor as the point of continuity throughout the project lifecycle. The tier controls weekly capacity and depth—not which person you get.

Weekly Dedication Tiers

The service offers flexible engagement levels based on project complexity and risk surface:

• Consultant (6 work hours weekly) — Oversight, guardrails, risk tracking, and light reviews.
• Architect (1 work day weekly) — Full design partnership with hands-on reviews, control choices, and CI/CD integration guidance.
• Custom — Tailored engagement structure based on unique project requirements, complex multi-workstream architectures, or extended full-time embedded advisory. Duration, scope, and time allocation designed collaboratively with Hacken.

Single Accountable Owner Model

Your embedded Security Advisor serves as the dedicated point of accountability throughout your security lifecycle:

• Provides multi-role support — Delivers hands-on technical guidance, security review oversight, process orchestration, and stakeholder communication as development needs shift.
• Maintains end-to-end continuity — Ensures consistent security posture and institutional knowledge across all workstreams, sprints, and project phases.
• Manages security documentation — Owns the creation and maintenance of threat models, risk registers, security requirements, and audit trails.
• Coordinates external assessments — When third-party audits or penetration tests are required, your advisor defines scope, selects vendors, manages engagement logistics, and serves as the single point of contact between your team and external security providers.
