What This Assessment Delivers

A comprehensive toolkit for documenting and communicating legacy risk to leadership.

Executive Risk Heat Map

Clear red, amber, green visibility across all systems for board-level reporting.

Evidence Checklist

What auditors and regulators actually expect to see documented.

Phased Roadmap

30, 60, 90-day risk reduction plan without requiring downtime.

Sample Output

Why Legacy Risk Belongs on the Board Agenda

Legacy risk is no longer a maintenance concern. It is an operational, security, and governance issue.

End-of-life frameworks and runtimes

Security vulnerabilities with unclear ownership

Inability to produce audit evidence

Inability to produce audit evidence

"Most legacy systems do not need an emergency rewrite. They need clarity."

This assessment documents exposure, constraints, and control gaps so leadership can decide timing and sequencing safely.

How the Scoring Model Works

Each system is evaluated across five dimensions: Security posture, Operational resilience, Release and rollback safety, Dependency concentration, and Compliance readiness.

0–15

Controlled

Risk is documented, monitored, and actively managed. Evidence is available. No urgent action required.

16–30

Elevated

Gaps exist in documentation, controls, or evidence. Remediation should be prioritized within 90 days.

31–40

Critical

Material exposure exists. Immediate board visibility and executive sponsorship required.

Evidence Checklist

What auditors and regulators expect to see documented.

  • MFA coverage
  • Dependency vulnerability scans
  • Access control model
  • Patch cadence

  • Incident response plan
  • Backup and recovery testing
  • Monitoring and alerting
  • Mean time to recovery metrics

  • CI/CD pipeline presence
  • Rollback and canary capability
  • Test coverage visibility
  • Release approval process

  • Audit artifacts
  • Change logs
  • Data handling documentation
  • Third-party risk visibility

If evidence cannot be produced, the risk is treated as present.

From Assessment to Control

A phased approach to reducing exposure without disruption.

Day 0

Chaos

Undocumented exposure, unclear ownership, hidden risk

First 30 Days

Visibility

Risk visibility, dependency mapping, evidence gaps identified

Next 60 Days

Control

High-risk items addressed, rollback and release controls added

By 90 Days

Reduced Exposure

Reduced exposure, documented posture, modernization options clarified

How This Assessment Informs Decisions

This framework is often used to:

Decide modernization vs stabilization

Choose refactor over rewrite

Prioritize zero-downtime controls

Validate whether outsourcing is safe

Designed For

  • CIOs and CTOs accountable for uptime and risk
  • Boards evaluating technology exposure
  • Audit and compliance stakeholders
  • Engineering leaders preparing for modernization
