Systems fail.

State corrupts.

Users misinterpret.

Irreversible actions happen.

We build for that.

audit --scope production
Active

Systematic review of production systems. Identifies vulnerabilities, failure modes, and security gaps. Findings are prioritized by blast radius and exploitability.

Code reviewArchitecture auditThreat modelRisk register

Duration: 2-4 weeks

Constraint:

Not a compliance checkbox. Findings require remediation commitment. We do not produce shelf-ware.

pentest --mode offensive
Active

Controlled offensive testing against live systems. We think like attackers so you can defend like one. Comprehensive reports with exploitation paths and verified fixes.

Penetration testingRed team operationsExploitation pathsRemediation plan

Duration: 1-3 weeks

Constraint:

Live system access required. No sandboxed demos. Results may be uncomfortable.

harden --policy fail-closed
Active

Implementing fail-safe defaults, rate limiting, input validation, and defense-in-depth controls. Building systems that fail closed, not open.

System hardeningGuardrail implementationFail-safe controlsIncident runbooks

Duration: 2-6 weeks

Constraint:

Requires architectural authority. Cannot bolt security onto systems with no ownership.

// known_failure_modes

Known Failure Modes

SILENT_STATE_CORRUPTION

Data mutates without detection. No alerts fire. Users discover the damage after the fact.

PERMISSION_ESCALATION

A regular user performs an admin action. The system allowed it because nobody tested the boundary.

IRREVERSIBLE_ACTION_WITHOUT_CONFIRMATION

A destructive operation executes on a single click. No undo. No confirmation gate.

CASCADING_TIMEOUT_FAILURE

One service times out. Retry logic amplifies the failure. The system enters a death spiral.

ASSUMED_TRUST_BOUNDARY

Internal services trust each other implicitly. An attacker inside the perimeter moves laterally without resistance.

RECOVERY_PATH_UNTESTED

Backup exists on paper. Nobody has run a restore. When the incident happens, the runbook fails.

If you recognize these patterns in your systems, that is the signal.

// engagement_protocol

Engagement Protocol

01

Threat Assessment

Define critical paths, assets, and failure boundaries.

PrerequisitesSystem access. Architecture documentation. Stakeholder availability.
OutputScoping document. Initial risk surface.
Duration1-2 weeks
02

Adversarial Mapping

Threat model the system. Identify attack surface. Challenge assumptions.

PrerequisitesPhase 01 complete. Technical team available for walkthroughs.
OutputThreat model document. Prioritized risk register.
Duration1-3 weeks
03

Controlled Testing

Test boundaries, permissions, and misuse cases against live systems.

PrerequisitesWritten authorization. Testing window agreed in advance.
OutputExploitation report. Verified vulnerability list.
Duration2-4 weeks
04

Hardening + Handover

Ship guardrails. Validate fixes. Deliver runbooks and incident playbooks.

PrerequisitesPhase 03 findings accepted. Remediation resources allocated.
OutputRemediation report. Verified fixes. Recovery procedures.
Duration1-2 weeks

Prerequisites

  • Production systems with real users or real assets at risk
  • Willingness to act on findings, not just collect reports
  • Technical stakeholder available for the duration of engagement
  • Written authorization for adversarial testing phases

Exclusions

  • Compliance-only engagements with no remediation intent
  • Pre-MVP products with no production risk surface
  • Organizations seeking a pentest PDF without engineering follow-through
  • Engagements without executive or technical sponsorship
