Services

The work of a security team, available on contract.

Six practice areas, from building and running defenses to testing them, tracking threats, and deciding what to do next.

Security Engineering & Operations

Detection engineering, log pipelines and SIEM, endpoint and infrastructure hardening, security automation, and incident response readiness. Built so it keeps working after the engagement ends.

Offensive Security & Assessments

Penetration testing, vulnerability assessments, and attack surface reviews. Every finding comes with severity, context, and practical remediation steps.

Cloud & Infrastructure Security

Hardening and review of AWS, Google Cloud, and Azure environments: identity and access, network segmentation, containers, and infrastructure as code.

Threat Intelligence

Monitoring of threat actors, data leaks, and exposed assets relevant to your business, delivered as short reports with clear priorities.

AI Security

Security reviews for AI adoption: LLM applications, prompt injection and data leakage risks, vendor evaluation, and internal usage policies.

Security Advisory

Security roadmaps, policies and standards, compliance readiness for SOC 2 and ISO 27001, and support with customer and vendor security questionnaires.

Approach

Senior work, straight answers.

No handoffs

The person you talk to is the person who does the work, from the first call to the final report.

Right-sized security

Advice proportionate to your risk and your budget. When something is not worth doing, you will hear that too.

Transparent by default

Clear scope, direct reporting, and documentation your team keeps after the engagement ends.
