Case Studies.
Selected engagements from across our global practice. Client names, exact scopes, and identifying metadata are intentionally redacted — what remains is the work, the methodology, and the measurable outcome.
DISCLOSURE PROTOCOLEvery engagement Alexa undertakes is governed by a strict mutual NDA and, in regulated sectors, by sovereign disclosure rules. The narratives below have been anonymised, generalised across multiple clients of the same profile, and approved for release. Any resemblance to a single identifiable client is unintentional.

Red Team for IT — Assumed Breach
End-to-end emulation of a state-aligned threat actor against a regional retail bank.
Challenge
Internal audit and regulator both flagged a maturing-but-untested SOC. Leadership wanted irrefutable evidence of how a sophisticated actor would move from initial foothold to core banking systems — without disrupting live transactions.
Approach
Six-week TIBER-EU style operation: OSINT, spear-phishing on a controlled cohort, compromise of a supplier laptop, lateral movement via Active Directory abuse, and a covert pivot toward the SWIFT segment. All actions executed under joint white-team oversight with hard kill-switches.

Security Assessment for OT (IEC 62443)
Safety-first OT visibility across a national-grid operator under active threat-actor interest.
Challenge
After regional incidents targeting energy operators, the utility needed an honest baseline of cyber-physical risk across SCADA, DCS and substation automation — without ever putting plant safety or grid stability at risk.
Approach
Three-month assessment combining read-only passive captures (Modbus, DNP3, IEC 61850, OPC-UA), engineering-station configuration review, IT/OT boundary audit, and tabletop exercises with operations crews. All hands-on activity scheduled inside maintenance windows.
Measured Outcomes
From generation sites to transmission grids — securing the systems nations depend on.

NIST 2.0 + CMMC L2 Continuous Compliance
Replacing a binder-driven audit cycle with a continuously-evidenced compliance fabric.
Challenge
The agency was burning thousands of staff-hours per cycle on manual evidence collection across overlapping FISMA, NIST 800-53, and CMMC obligations — with mounting findings on control drift between audits.
Approach
Mapped controls into a single canonical catalogue, instrumented infrastructure with policy-as-code (OPA, Checkov), automated evidence capture into an immutable store, and stood up a real-time control-health dashboard for both engineering and the IG.

Secure SDLC by Design (BSIMM-aligned)
Embedding security into a 200-team engineering org without slowing delivery.
Challenge
A two-year vulnerability backlog, unclear ownership, and an engineering culture that treated AppSec as a release-day blocker. Leadership wanted measurable improvement inside one year — without adding gating that would push teams to bypass.
Approach
BSIMM diagnostic, threat modelling cadence in sprint rituals, SAST / SCA / IaC / secrets scanning wired into PR gates with severity-based blocking, a Security Champions program across all 14 product lines, and an executive scorecard surfacing vulnerability burndown by line.
Measured Outcomes
Where federal mandates, classified workloads, and national security converge.

Orchestrated Defense Fabrics — Tool Sprawl Remediation
Collapsing 28 disconnected security tools into a single coherent defense fabric.
Challenge
Years of tactical procurement had produced 28 partially-overlapping security products generating ≈ 4M alerts/day, with analysts triaging less than 9% of them. SOC fatigue was driving high attrition.
Approach
Inventoried the toolchain, designed a unified data fabric with normalised telemetry, built SOAR playbooks for the top 12 alert classes, retired or consolidated 11 tools, and rebuilt the SOC operating model around a tier-less analyst pod structure.

DevSecOps + Continuous Compliance
Hardening the trading-platform pipeline without adding a single second to release latency.
Challenge
Regulators across two jurisdictions were sharpening expectations on software supply chain integrity for trading systems. The bank needed evidence — not a policy document — and could not tolerate added release latency on time-sensitive trading code.
Approach
Re-architected the build pipeline with provenance attestations (SLSA L3-aligned), signed artefacts, isolated build runners, and break-glass review only for high-impact components. Compliance evidence emitted directly from the pipeline into the audit store.
