THREE DELIVERY LINES

Senior engineering for systems that are difficult to change, operate, or safely expose.

We enter where systems are difficult to change, incidents cross multiple technical layers, or internal teams need experienced engineering judgment.

WHEN TO TALK

Bring us the system you cannot safely change by guesswork.

01ARCH + REL / 01

Critical Systems Architecture & Reliability

Design and modernize resilient cloud, hybrid and on-premises systems, then operate reliability through explicit SLOs, observable signals, capacity and service-incident management, controlled change and tested recovery.

  • Resilience architecture, modernization and migration
  • SLI/SLO, observability, capacity and service-incident management
  • Controlled change, failover, recovery exercises and handover
02SEC / 02

Security Engineering

Assess exploitable paths, harden systems and verify remediation, then improve detection, containment and recovery.

  • Assessment, penetration testing and verified remediation
  • Identity, privilege and attack-surface reduction
  • Incident readiness, DDoS protection and ransomware recovery
03AI / 03

Private AI & Automation

Design private AI and automation around explicit data flows, provider boundaries and decision rights.

  • AI × human expertise amplifies human experience and imagination
  • Customer data must not be used to train AI models
  • The more powerful AI becomes, the stricter its boundaries should be

SECURITY ENGINEERING / CONTROLLED EXPOSURE

Five modules. One evidence-led security lifecycle.

The first three modules form the core security delivery. DDoS and ransomware are specialist resilience modules added where the threat and business impact justify them.

CORE SECURITY DELIVERY

SEC / 01

Security Assessment & Targeted Penetration Testing

Find exploitable paths, establish business impact and verify remediation under written Rules of Engagement.

BEST FOR
When you need to know which weaknesses are exploitable in the agreed environment and what must be fixed first.
SCOPE
Authorized applications, APIs, identity paths, cloud configuration and network exposure named in the Rules of Engagement.
WHAT WE DO
Combine evidence-led review, automated discovery and controlled manual testing. Validate exploitability only where explicitly authorized and safe, and stop at the minimum evidence needed to prove impact.
DELIVERABLES
Scope and Rules of Engagement record; reproducible findings; business-impact and exploitability ranking; prioritized remediation plan; retest results.
ACCEPTANCE EVIDENCE
Asset-coverage record, tested-path log, minimum sufficient reproduction evidence and before-and-after retest status.
SCOPE NOTE
Testing is limited to the signed Rules of Engagement; automated findings require manual validation, while social engineering, red-team activity, destructive testing, denial-of-service and persistence require separate authorization.
SEC / 02

Hardening & Attack-Surface Reduction

Reduce unnecessary exposure and privilege, then prove the before-and-after state.

BEST FOR
When external exposure, privilege or configuration drift has expanded faster than ownership and review.
SCOPE
Internet-facing exposure, identities and privileged paths, cloud services, networks, operating systems, containers, applications, secrets handling and administrative workflows.
WHAT WE DO
Establish the baseline, remove or isolate unnecessary exposure, reduce privilege, harden configuration, control egress and stage changes with acceptance and rollback gates.
DELIVERABLES
Before-and-after attack-surface and privilege map; hardened configuration baseline; change plan and record; exceptions and residual-risk register.
ACCEPTANCE EVIDENCE
Configuration diff, verified exposure checks, privilege-path comparison and rollback or exception evidence.
SCOPE NOTE
Implementation follows the approved systems, access and change windows; external dependencies and residual risks are recorded in the deliverables.
SEC / 03

Detection & Incident Readiness

Turn telemetry into owned, tested detection, escalation and containment paths.

BEST FOR
When alerts exist but ownership, escalation, containment authority and recovery decisions have not been tested.
SCOPE
Priority attack paths, telemetry sources, detection logic, alert routing, incident roles, communications, containment actions and decision gates.
WHAT WE DO
Map high-consequence scenarios, tune actionable detections, define triage and escalation, build response runbooks and exercise the response path.
DELIVERABLES
Detection-coverage map; tuned rules and test cases; incident roles and escalation matrix; response runbooks; exercise report and improvement backlog.
ACCEPTANCE EVIDENCE
Synthetic-event or approved-replay results, alert-to-owner evidence, timed tabletop or technical-exercise results and assigned gap owners.
SCOPE NOTE
This module covers detection and incident readiness; continuous monitoring requires separate coverage.

SPECIALIST RESILIENCE MODULES

SEC / 04

DDoS Protection

Protect public services through layered provider, edge, origin and degraded-service controls.

BEST FOR
When a public service has material availability or cost-exhaustion risk and current protection depends on one provider setting or perimeter.
SCOPE
DNS, CDN/WAF, upstream-provider and origin dependencies; L3/L4 capacity; L7 resource exhaustion; quotas, autoscaling and cost-amplification risk.
WHAT WE DO
Review upstream capacity and dependencies, isolate origins, define rate, queue and admission controls, test failover, set degraded-service objectives and establish provider escalation paths.
DELIVERABLES
Dependency and exposure map; DDoS protection design; origin-isolation and control configuration; failover and degraded-mode runbook; provider escalation matrix; quota and cost-risk register.
ACCEPTANCE EVIDENCE
Origin-reachability checks, rate/queue/admission-control results, controlled failover exercise, provider-contact validation and measured degraded-mode behavior.
SCOPE NOTE
Validation uses controlled scenarios; traffic scrubbing and upstream capacity remain with the contracted provider.
SEC / 05

Ransomware Containment & Recovery

Separate recovery authority, protect clean copies and rehearse a measurable path back to service.

BEST FOR
When identity compromise, backup deletion or administrative-plane takeover could stop the business or make restoration untrustworthy.
SCOPE
Identity and privilege recovery; management-plane isolation; backup administration and deletion authority; retention lock or immutable copies; clean-room, golden-image or infrastructure-as-code recovery; restoration order; application and data validation.
WHAT WE DO
Map the blast radius, separate recovery authority, harden backup paths, define clean recovery, rehearse prioritized restoration and record observed gaps.
DELIVERABLES
Ransomware dependency and blast-radius map; protected-recovery design; controlled-recovery runbook; recovery sequence; exercise report and gap register.
ACCEPTANCE EVIDENCE
Agreed RTO/RPO targets, measured recovery time, observed data loss, integrity results and gap register.
SCOPE NOTE
Recovery capability is measured against the agreed scenario, available clean copies and system dependencies.

WAYS TO ENGAGE

Three explicit commercial shapes.

Scope, decision rights, evidence and exit conditions are agreed before work begins.
01

Assessment & Design

Time-bounded investigation and design for a defined system, risk or decision.

Output: verified current state, target design, priorities, acceptance conditions and implementation scope.
02

Implementation & Remediation

Delivery against an agreed plan, with controlled change, validation, rollback evidence and customer handover.

Output: implemented controls, change record, acceptance evidence and residual-risk register.
03

Bounded Engineering Retainer

Reserved senior engineering capacity for an agreed system and backlog, with defined scope, service window, decision rights and review cadence.

Service windows, response expectations and escalation paths are defined in the retainer.

HOW WE WORK

From defined authority to customer-owned evidence.

Our delivery history includes client systems designed and operated against availability objectives up to 99.99%. Each engagement defines the objective, measurement method, responsibilities and remedies for the actual system.
  1. 01
    Authorize & Bound

    Before technical work begins, confirm lawful authority, outcomes, scope, decision rights and stop conditions. Work stays in the customer environment where practical; required access is approved, least-privileged, task-limited and expiring, while service-side technical copies follow published deletion deadlines.

    AUTHORITY / SCOPE / STOP
  2. 02
    Map & Prioritize

    Trace dependencies, data and identity paths, failure domains and business impact; separate observed facts from assumptions.

    DEPENDENCY / TRUST / RISK
  3. 03
    Design & Plan

    Define the target state, controls, service objectives, acceptance conditions, rollback and the sequence of change.

    TARGET / CONTROL / PLAN
  4. 04
    Implement & Control

    Apply agreed changes in stages, verify each gate and preserve a safe path back.

    CHANGE / GATE / ROLLBACK
  5. 05
    Validate & Exercise

    Test the resulting state, exercise response or recovery paths, measure outcomes and record residual risk.

    TEST / MEASURE / RETEST
  6. 06
    Handover & Prove

    Return ownership through customer-held documentation, operational runbooks, evidence, known gaps and an explicit exit path.
