Zero-Trust Architecture

Deterministic Systems and Zero-Trust Architecture

We build and refactor backends where resilience is mission-critical. We design systems with data-level access isolation (Row Level Security, Security Definer), strict ACID transactional integrity, and delivery pipelines where every change passes verifiable security controls before reaching production.

The challenge

Transactional systems and backends for regulated environments have a minimal margin for error. A misconfigured access policy, an uncontained privileged function, or a pipeline that skips controls during a hotfix can irreversibly compromise data or financial assets.

What we can deliver

Row Level Security (RLS) policies in PostgreSQL with isolation by tenant, role, and session context
Audited Security Definer functions to control privileged access without exposing internal schemas
ACID integrity audits: transactions, rollbacks, deadlocks, and consistency under concurrent writes
CI/CD pipelines with integrated security controls (SAST, SCA, secrets management, branch protection)
Infrastructure hardening: runners, IAM roles, network policies, and service segmentation
Infrastructure as code (Terraform/Pulumi) with full change traceability

Target outcomes

Data access isolated with verifiable policies at the database level
Auditable releases with risk visible before changes reach production
Infrastructure ready to meet regulated environment compliance requirements

A zero-trust architecture starts from the assumption that no component is trusted by default — not even internal services. Every access, every transaction, and every infrastructure change is designed to be verifiable, reversible, and traceable.

Your critical infrastructure deserves an honest technical assessment.
