Engineering Case Studies
Long-form architecture write-ups from our engineering team — reference designs for secure, regulated, and AI-driven systems, at the depth we build them. Capability, not client name-drops: no confidential details, no invented numbers.
Designing an Incident-Response and Forensic-Readiness Platform
A reference architecture for an evidence plane, case-centric detection and reversible containment that preserves volatile state, built to survive an attacker who holds production admin rights.
Tamper-Evident Audit Logging for Defensible Evidence Retention
How to architect an append-only audit log whose integrity can be mathematically proven later, not just trusted at write time.
Reference Architecture: Kubernetes Runtime Security & Admission Control
How to layer admission control, workload isolation, and runtime detection into Kubernetes clusters so misconfigurations and compromised containers are caught before and during execution.
Identity and Access Management with Least-Privilege Enforcement
A reference architecture for IAM that treats every credential as attack surface: short-lived tokens, policy-as-code, and provable least privilege instead of static roles.
A Defence Architecture for Prompt Injection and Tool Abuse in LLM Agents
How to contain an LLM agent that reads untrusted content and calls tools, so a poisoned document or web page can't hijack its actions.
Software Supply-Chain Integrity: SLSA Provenance and Signing
A reference architecture for build provenance, hermetic builds, and cryptographic signing that makes a tampered artifact detectable before it reaches production.
A Zero-Downtime Secrets Management and Rotation Architecture
How to design a secrets platform where every credential is short-lived, every access is attributable, and rotation never causes an outage.
Architecting a Threat-Detection and Alerting Pipeline for a SOC
How to design a detection-and-alerting pipeline that turns noisy telemetry into triage-ready alerts a SOC can actually act on, without drowning analysts.
Multi-Tenant Isolation Architecture for a SaaS Platform
How tenant boundaries are designed to survive a compromised neighbor: pooled infrastructure with enforced isolation, scoped keys, and contained blast radius.
Designing a Passwordless Authentication System with WebAuthn and Passkeys
How we architect passwordless login: WebAuthn/FIDO2 credential flows, passkey sync trust boundaries, recovery paths, and the failure modes teams underestimate.
Zero-Trust Network Segmentation for a Regulated Cloud Workload
How we replace a flat, perimeter-trusted VPC with identity-based microsegmentation, policy-as-code enforcement, and tamper-evident audit trails for regulated workloads.
Data-Protection Architecture for Clinical Research
How sensitive clinical and research data is architected for least-privilege access, layered encryption, tamper-evident audit trails, and GxP/HIPAA/GDPR-style regulatory alignment.
Email Security and Anti-Phishing Architecture
How SPF, DKIM and DMARC, gateway filtering, business-email-compromise defenses, and awareness training combine into a layered anti-phishing architecture for a professional-services firm.
OT/ICS Security Architecture for a Smart Factory
How a smart-factory floor is segmented into IEC 62443 zones and conduits, given protocol-aware monitoring and brokered remote access, without pretending the plant can be patched like IT.
PCI DSS Forensic Investigation Architecture
How a PFI-style payment-card investigation is architected: evidence preservation, chain of custody, cardholder-data-environment scoping, and a defensible workflow that survives scrutiny.
Pre-Launch Security Architecture Review for a Mobile Banking App
How a mobile banking app is threat-modeled, hardened against a hostile device, and made pen-test-ready before launch — treating the client as untrusted and the backend as the real boundary.
Ransomware Containment for a Multi-Site Network
How we architect rapid segmentation, blast-radius limiting, identity lockdown, and EDR isolation to stop ransomware spreading across many sites — the hospitality multi-site pattern, generically.
Ransomware Recovery and Resilience Architecture
How we design detection, isolation, immutable backups, and clean-room rebuild so a network like a school district's can recover from ransomware without paying and without guessing.
Security Architecture and Audit Methodology for a Cross-Chain Bridge
How a cross-chain bridge's trust model, validator/relayer set, and replay defences are architected and audited — treating the bridge as the highest-value target in DeFi.
Security Architecture for a Fleet Management / Telematics Platform
How a telematics platform is architected for device identity, signed OTA updates, API hardening, and tenant isolation when the endpoints are vehicles you cannot physically trust.
