Pillar 05

Quality Engineering, Security & Privacy

AI red-team testing, application security reviews, release-readiness checks, test automation and privacy engineering.

When to involve us
When you need to reduce technical risk and release with more confidence.
Usually for
CTO, QA, security and product leaders

What does Quality, Security & Privacy cover?

Quality Engineering, Security & Privacy is the Directrix Technologies practice for reducing technical risk before and after release. It covers functional, automated, API and performance testing, accessibility checks, application security reviews, threat modelling, AI red-team testing against the OWASP Top 10 for LLM Applications, access-control reviews and privacy engineering. Every finding is reproducible, severity-rated and paired with fix guidance, and each report states exactly what was and was not tested.

Recommended starting pointAssessment / project

AI red-team and abuse-case testing

Probe a defined AI application for prompt injection, data leakage, unsafe tool use and other relevant failure modes.

What you get

  • Test plan
  • Observed failures
  • Risk ranking
  • Mitigation recommendations
  • Retest

Sounds familiar?

AI features may be vulnerable to adversarial inputs or unintended actions.

Typical uses

RAG assistants, agents, support bots, document workflows.

Usually for

AI lead, security, product

Good to know: Coverage is bounded by agreed scope and test environment.

Discuss AI red-team and abuse-case testing
Recommended starting pointAssessment

Application security review

Review a defined application scope for common security weaknesses and remediation priorities.

What you get

  • Scope statement
  • Findings
  • Risk ratings
  • Remediation guidance

Sounds familiar?

Security risks may be introduced through code, configuration or access design.

Typical uses

Web applications, APIs, admin panels.

Usually for

CTO, security lead, product owner

Good to know: A scoped review is not a guarantee of security or a substitute for a required independent certification.

Discuss Application security review
Recommended starting pointAssessment

Release readiness and production check

Use a structured checklist for tests, rollback, access, monitoring and operational ownership before release.

What you get

  • Readiness checklist
  • Open-risk list
  • Go/no-go inputs
  • Launch plan

Sounds familiar?

Features ship without an agreed operational readiness review.

Typical uses

MVP-to-production transitions, major releases.

Usually for

Engineering manager, product owner, operations

Recommended starting pointAssessment / project

AI governance and documentation support

Document use cases, data sources, model choices, limitations, human oversight and monitoring responsibilities.

What you get

  • System inventory
  • Risk notes
  • Technical documentation
  • Monitoring responsibilities

Sounds familiar?

Teams cannot clearly explain how an AI feature is built or controlled.

Typical uses

Enterprise AI deployments, internal assistants, customer features.

Usually for

AI lead, risk, compliance, product

Good to know: Does not by itself certify compliance with any law or standard.
