Who We Are

Security That
Actually Works

RETACH is a digital governance and cybersecurity firm focused on helping organizations fix foundational technology risks. We work with businesses that are growing, digitizing, or facing compliance pressure — but lack a clear structure for managing risk.

We bridge the gap between strategy and execution, policy and implementation, tools and actual security outcomes. Using the S.I.N.S. Framework™, RETACH provides a practical path from risk exposure to resilient operations.

Our Philosophy
Visibility over assumption
Know what you have before you secure it
Control over complexity
More tools is not the answer — better governance is
Discipline over dependence
Build internal capability, not vendor lock-in
Continuous improvement
Security is a journey, not a destination

Built for African Realities

  • Limited budgets with maximum exposure
  • Hybrid infrastructure across cloud and on-premise
  • Rapid digitization outpacing security maturity
  • Growing compliance pressure from local and global regulators
  • Shortage of in-house cybersecurity expertise

RETACH is not a framework competitor — we are an implementation alignment layer that translates global standards into practical, executable security programs.

Paul N. Nduati, CISSP, CASP+ is a certified cybersecurity practitioner and digital governance strategist with over a decade of experience securing enterprise systems across critical infrastructure and regulated sectors.

His career spans the full technology governance lifecycle — from designing secure identity and access frameworks and hardening enterprise Active Directory environments, to implementing firewall policy, cloud security posture management, and organisational compliance programmes aligned to ISO 27001, NIST CSF, and applicable data protection and cybercrime legislation.

The S.I.N.S. Framework™ was built from that practice — not from theory. Every methodology RETACH applies was first tested inside real enterprise environments, including mission-critical national infrastructure. That practitioner foundation is what separates RETACH from advisory-only firms.

RETACH Digital Ltd exists to make enterprise-grade security governance practical, measurable, and affordable for any organisation navigating growth, digitisation, or compliance pressure — wherever they operate.

The S.I.N.S. Framework™

Four Pillars.
One Approach.

Most firms sell tools or give high-level advice. RETACH focuses on execution — identifying real issues, fixing configurations, and aligning your technology with your business needs.

S
Systems
Foundation Layer

Establishing secure, well-governed enterprise systems that form the backbone of your digital operations.

  • ERP & business system hardening
  • Identity & access management
  • Endpoint configuration & control
  • Asset inventory & lifecycle management
I
Infrastructure
Operational Layer

Securing the underlying infrastructure that supports all your business services and applications.

  • Cloud security posture management
  • Server hardening & configuration
  • Backup & disaster recovery design
  • Hybrid environment governance
N
Network
Connectivity Layer

Designing and protecting the communication fabric that connects your people, systems, and data.

  • Network segmentation & zoning
  • Perimeter defense & firewall policy
  • Secure remote access (VPN/Zero Trust)
  • Traffic monitoring & anomaly detection
S
Security
Governance Layer

Building the policies, people, and processes that sustain security outcomes over time.

  • Security policy & procedure development
  • Risk assessment & treatment
  • Compliance program management
  • Awareness training & culture
Strategy → Execution
We don't just advise — we implement. Every engagement ends with working controls, not slide decks.
Policy → Implementation
Governance without operational grounding is theater. We make policy real through practical implementation.
Tools → Outcomes
Technology only matters when it produces measurable security outcomes. We connect the two.
The S.I.N.S. Process

Assess. Quantify.
Remediate.

A structured five-step journey — from your first score to continuous assurance.

01
S.I.N.S. Assessment
Complete the free 20-question scanner. Get your instant resilience score across all four pillars.
02
Health Scan
Our consultants run a structured deep-dive. Every gap is found, scored, and documented.
03
Risk Quantification
The CRQ Engine produces your financial risk position — Expected Annual Loss, 75th/95th percentile loss bands, and regulatory fine exposure — in your currency.
04
Remediation
We implement the fixes — configurations, policies, and controls — not just recommendations.
05
Continuous Assurance
Ongoing virtual CISO support, monitoring, and quarterly reviews to sustain your posture.
How RETACH Arrives at Your Number

The math behind
the model.

No black boxes. Every figure RETACH produces traces back to a calculation you can verify — in plain English.

01
Count how often attacks happen
We start with the annual probability of each attack type — phishing, ransomware, fraud, data breach, business continuity failure, insider threat. These base frequencies come from Serianu Africa Cybersecurity Report 2023, CBK incident data, and Communications Authority of Kenya quarterly reports. A SACCO faces attacks 1.8× more often than a baseline organisation. A Fintech, 2.4× more. These are not assumptions — they are published sector frequencies.
02
Estimate how much each event costs
Severity is modelled as a percentage of annual revenue — because an organisation's revenue is the most reliable proxy for the scale of data held, transactions processed, and operational complexity. Ransomware typically costs 18% of annual revenue when it hits. A data breach costs 12%. These percentages are calibrated to East Africa incident cost data and validated against global benchmarks from IBM Cost of a Data Breach 2023 and Zurich Insurance emerging markets loss data.
03
Multiply: Expected Loss = Frequency × Severity
This is the same formula an insurance actuary uses to price a premium. If ransomware has a 30% annual probability of hitting your organisation and costs KES 9M when it does, your expected annual loss from ransomware is KES 2.7M. We calculate this for six attack types and sum them. That total is your Expected Annual Loss — what you should expect to lose, on average, in any given year.
EAL = Σ (Frequency × Severity) across all six S.I.N.S. scenarios
04
Adjust for your specific controls
Your controls reduce your risk. Full MFA cuts overall exposure by 38%. A tested and documented backup procedure cuts it by 30%. ODPC registration reduces regulatory fine exposure by 12%. Your S.I.N.S. score — derived from the four-pillar assessment — applies a continuous modifier: a score of 100 produces 85% risk reduction; a score of 0 produces 85% risk amplification. Every organisation retains a minimum 12% residual risk floor — no organisation is immune. Control efficacy percentages are sourced from NIST SP 800-53 and CIS Control implementation benchmarks.
05
Show three scenarios, not one number
Losses are not smooth. Some years are quiet. Some are catastrophic. We model this using a lognormal distribution — the same statistical shape that insurance actuaries use for catastrophe losses — because cyber losses have a long tail: most years cost less than average, but rare years cost far more. The spread of that distribution is calibrated by sector: Fintechs have higher variability (σ=0.95) than County Governments (σ=0.65). Critical Infrastructure sectors carry the highest dispersion (σ=1.10) — reflecting nation-state threat exposure and OT/IT convergence — and the highest regulatory tier, where Data Protection Act 2019 and Computer Misuse & Cybercrimes Act 2018/2024 s.18 penalties can apply simultaneously for a single failure. This gives you three outputs: your median year, a bad year (75th percentile), and a very bad year (95th percentile — 1 in 20 chance).
95th percentile = exp(ln(EAL) + 1.645 × σ)  ·  The stress-test figure for board reporting and insurance sizing.
