Cybersecurity & Digital Protection.
Most security problems are architectural. They are decided long before an assessment finds them — in how a service authenticates, where a secret is stored, what an API returns when it is asked the wrong question, and which internal system can reach which database. Reviewing that after launch is the expensive way to discover it.
We work on the side of the problem where it is still cheap to change: the design of the system. That means threat surface considered while the architecture is being drawn, controls implemented as part of the build rather than bolted to the outside of it, and the operational visibility to know what is actually happening once the platform is live.
Where a system already exists, the work starts with understanding it honestly — what it runs, what it exposes, who can reach it, and what the realistic consequences of each weakness are — and ends with remediation you can verify rather than a document you file.
Security architecture
Security is a property of the whole stack.
A request crosses five tiers before it becomes data at rest. Each one has its own failure modes, its own controls, and its own way of being got around — which is why security applied at a single tier is a boundary rather than a posture.
Security perimeter
05 tiers · continuously validated
- 01
Application
What the user touches
The web and mobile surface, and everything reachable from it. Input handling, session management, output encoding, dependency hygiene, and the client-side assumptions that turn into server-side problems.
- Input validation
- Session management
- Output encoding
- Dependency review
- Secure defaults
- 02
API
The contract between systems
Every endpoint is an entry point. Authorisation is enforced per object rather than per route, rate limits and quotas are treated as security controls rather than billing features, and error responses are written so they do not answer questions they were not asked.
- Per-object authorisation
- Rate limiting
- Schema validation
- Token handling
- Error hygiene
- 03
Identity
Who is allowed to do what
Authentication, multi-factor enrolment, role and permission design, service-to-service credentials, and privileged access. Most breaches are an identity problem before they are anything else, and permission models are the part of a system that quietly rots as a team grows.
- Authentication flows
- Multi-factor
- Role design
- Privileged access
- Service credentials
- 04
Cloud
Where it runs
Network boundaries, workload isolation, storage exposure, secret management, and the configuration drift that turns a correct deployment into an incorrect one over six months. Infrastructure defined as code so its security posture can be reviewed like any other change.
- Network boundaries
- Workload isolation
- Secret management
- Configuration review
- Infrastructure as code
- 05
Data
What is worth taking
Encryption in transit and at rest, key handling, retention and minimisation, backup and restore that has actually been tested, and the access paths that decide whether a single compromised component becomes a single compromised record or all of them.

Capabilities
What we actually do.
Engagements are usually a subset of this list, scoped to the system in front of us. Nothing here is a product we resell — it is engineering work carried out on your platform.
- 01Application Security
- Security work across the development lifecycle of web and mobile applications: threat modelling during design, secure implementation patterns, code review of security-relevant paths, and verification before release.
- 02Cloud Security
- Review and hardening of cloud infrastructure, workload configuration, network boundaries, storage exposure, secret management, and the access controls that govern the environment itself.
- 03Security Audits
- A structured review of a system's architecture, configuration and controls to identify gaps, misconfigurations and design weaknesses — with findings written so an engineer can act on them, not only a manager.
- 04Vulnerability Assessment
- Discovery of vulnerabilities across applications, dependencies and infrastructure, triaged by realistic exploitability and business consequence, with remediation guidance for each finding rather than a scanner export.
- 05Penetration Testing
- Authorised security testing of applications, APIs, infrastructure and systems, carried out under written scope and permission from the system owner. Results are reproducible: every finding comes with the steps to confirm it and the steps to close it.
- 06Identity & Access Security
- Authentication and authorisation design, multi-factor enrolment, role and permission models, privileged access controls, and the service-to-service credentials that are usually the least examined part of a platform.
- 07API Security
- Protecting APIs against unauthorised access, broken object-level authorisation, abuse and enumeration, insecure configuration, and the common application-layer weaknesses that scanners rarely reach.
- 08Data Protection
- Encryption in transit and at rest, key management, secure storage design, data minimisation and retention, and backup strategy — including restore procedures that have been tested rather than assumed.
- 09DevSecOps
- Security controls integrated into the software delivery lifecycle: dependency and secret scanning in CI, policy checks on infrastructure changes, signed and reproducible builds, and security review as part of the normal pull-request path.
- 10Security Monitoring & Incident Readiness
- Logging that captures what an investigation will need, alerting tuned to be acted on rather than ignored, detection coverage for the paths that matter, and the response preparation that decides how a bad day goes.
Penetration testing and any other active testing is performed only with the documented authorisation of the system owner, under an agreed scope. Moonpie does not claim security certifications or compliance accreditations it does not hold; where an engagement needs to align with a specific framework, that is scoped explicitly at the outset.
Approach
Five stages, in this order.
The order matters more than the length. Assessing a system you have not mapped produces findings you cannot rank, and hardening before ranking spends the budget on whatever was found first.
01
Discover
Map the real system.
Applications, infrastructure, data flows, identities, integrations and third parties — what exists, what talks to what, and what is exposed. Documentation and reality are rarely the same system, and the difference between them is usually where the risk lives.
02
Assess
Find what is wrong.
Vulnerabilities, misconfigurations, weak controls and architectural risks, identified through review and — where authorised — active testing. Every finding is recorded with the evidence needed to reproduce it.
03
Prioritise
Rank by consequence.
Findings are ordered by realistic exploitability and business impact, not by scanner severity. A theoretical issue behind three controls does not outrank an exposed credential, and treating them as equal is how remediation budgets get spent badly.
04
Harden
Fix it properly.
Remediation and control implementation, at the layer where the problem actually is. Fixes are verified after the change rather than marked closed on report, and the ones that are architectural are treated as architecture.
05
Monitor
Keep the posture.
Logging, detection, alerting and response readiness, plus the review cadence that keeps a hardened system hardened as it changes. Security posture decays by default — this is the stage that decides how quickly.
Connected work
Security is not a separate department.
This work is done by the same practice that builds the systems, which is the point: the fastest way to secure an architecture is to be in the room while it is being designed.
- Software EngineeringSecure implementation patterns, reviewed code paths, and dependency hygiene as part of normal delivery.
- Cloud & InfrastructureNetwork boundaries, workload isolation and secret management, defined as code and reviewable as change.
- AI & Intelligent SystemsAccess control and data handling for model inputs, retrieval sources, tool use, and everything an agent can reach.
- How we workSecurity posture is a stage of the delivery process, not a gate bolted to the end of it.
Build with securityfrom the beginning.
