Zero Trust
No implicit trust zones. Every request — auth, authorization, context and logging, regardless of source.
Security Architecture · /cyber-security/security-architectureZERO TRUST · DEFENSE-IN-DEPTH
Design security before the first commit is written
Design of SaaS, cloud or corporate networks based on Zero Trust and Defense in Depth. Threat model, architecture diagrams, hardening guides, compliance map.
Fits both new projects and the refactor of existing systems.

Principles
Four pillars of modern security architecture
Defense in Depth
Layered defence: perimeter, network, app, data. Each layer works even if another fails.
Least Privilege
Minimal necessary rights — for people, services, roles. Access is granted per task and revoked automatically.
Auditability
Every meaningful action — a log. SIEM-friendly format, retention, search, correlation and clear alerts.
Deliverables
What you get
Threat model
STRIDE/MITRE breakdown for key processes with countermeasures and prioritised mitigations.
Architecture diagrams
Zones, segments, data flows, trust, control points. Clear to the team, auditor and regulator.
Hardening guides
Checklists for servers, networks, databases, cloud, IAM, containers and Kubernetes.
Compliance map
Mapping your controls to ISO 27001, PCI DSS, SOC 2, GDPR — what's there and what's missing.
Who it's for
Teams building or rebuilding systems
/ 01
New SaaS
Designing security from scratch: architecture, IAM, encryption, logging, secrets management.
/ 02
Cloud projects
AWS / GCP / Azure: landing zones, VPC, security groups, KMS, audit, account organisation.
/ 03
Corporate network
Segmentation, NAC, VPN, remote-employee access, legacy system protection.
/ 04
Compliance projects
Preparing for ISO 27001, PCI DSS, SOC 2 — we set up the processes and documentation.
How it goes
Five steps from inquiry to support
1
Inquiry and context
We learn about the project: stage, technologies, regulation, risks, constraints.
2
Current state
We review existing architecture (if any). Identify growth points and bottlenecks.
3
Threat model + design
Model threats, work through the target architecture. Discuss alternatives.
4
Documentation
Deliver diagrams, threat model, hardening guides, compliance map.
5
Implementation support
We support the implementation team, answer questions, review architecture PRs.
Inquiry
Request a security architecture design
Describe the project and stage — details get discussed in DevBay's secure chat.
- NDA from the first message
- Documentation in formats the team can use
- Implementation support and PR review
- Compliance mapping on request
Project parameters
After submission we open a dialog in the internal chat — that's where we continue.
Ready to build security in from the start?
Describe the project — we'll map the threats, design the architecture, hand over the docs and help implement.
