Service 3
Requirements Feasibility Assessment
Too many organisations have the wrong people in the wrong roles and the right people are overlooked entirely. We go on-site to perform in-depth capability assessments of your security teams, audit daily activities, processes, and procedures, and then deliver a clear, actionable plan to restructure and build the teams your organisation actually needs. This service extends across cybersecurity, AI/ML, blockchain, and development teams.
Cybersecurity Team Assessment
Preliminary security audits on existing teams and individuals. We evaluate skills, gaps, and readiness, then recommend restructuring for maximum effectiveness.
AI & Machine Learning Teams
Assess whether your organisation has the right people to implement AI and ML initiatives. We identify skill gaps and map roles to your strategic objectives.
Blockchain Implementation Teams
Evaluate technical readiness for blockchain adoption, from smart contract developers to consensus architecture specialists and integration engineers.
Development Teams
Assess developer capabilities across Python 3, Rust, Node.js, .NET, Java, C++, and emerging frameworks. We scope team composition for current and future projects.
Process & Procedure Analysis
We observe and document daily workflows, operational procedures, and team interactions to identify inefficiencies, misaligned roles, and untapped potential.
Social Engineering & Security Awareness
Assess staff susceptibility to social engineering attacks and deliver tailored awareness training programmes to strengthen your organisation's human-layer defences.
Team Building Roadmap
A detailed, prioritised plan for building or restructuring your teams, including role definitions, hiring recommendations, training paths, and timeline milestones.
Talent Misalignment Analysis
Decades of consulting experience have shown that the right people are often in the wrong seats. We identify high-potential individuals who would be far more effective in security, AI, or development roles.
