Where audits usually start

Code risk rarely announces itself cleanly.

It shows up as slower releases, unclear ownership, brittle features, security concerns, failed handoffs, and rising maintenance cost.

01

Delivery keeps slowing down

Small changes take longer because architecture, dependencies, tests, and ownership are harder to reason about.

See the audit story
02

Risk is hard to prioritize

Teams know there is debt, but not which issues matter most or what should be fixed first.

View scorecard
03

Security concerns are scattered

Auth, permissions, dependencies, data flows, and logging often need a structured review before scale.

Review audit areas
04

Modernization needs a clear map

Before refactoring, migrating, or adding AI, leadership needs a grounded view of what the code can support.

Who the audit is for

Built for decision-makers, not just developers.

Each audit is scoped around the business decision the codebase needs to support, whether that is modernization, investment, acquisition, compliance, or release readiness.

CTOs and engineering leaders

Validate the inherited codebase.

Identify architecture risk, team process gaps, modernization needs, and delivery blockers before they compound.

Plan an engineering audit →
PE firms and investors

Quantify technical risk before closing.

Understand debt load, staffing needs, remediation cost, scalability concerns, and deal exposure with an independent view.

See due diligence examples →
M&A and acquirers

Know what integration will really cost.

Evaluate code quality, architecture, security, compliance, and integration risk before signing or scaling the asset.

Review acquisition cases →
The audit story

From unknown code risk to a ranked remediation plan.

The goal is not to shame the codebase. The goal is to create a clear operating picture for what to fix, what to monitor, and what can safely wait.

A useful code audit connects technical findings to business consequences: what blocks delivery, what creates risk, what affects reliability, and what should be fixed before the next major investment.

What Sphere analyzes

Six dimensions. One complete picture.

Sphere’s senior engineers go beyond surface-level review, assessing every layer of the technical stack so the final report is useful to both engineering and leadership.

Security and vulnerabilities

Authentication, authorization, sensitive data handling, injection risks, dependency exposure, and OWASP-style vulnerability patterns.

Surfaces exploitable gaps before they become incidents.

Performance and scalability

Bottlenecks, N+1 queries, memory leaks, infrastructure constraints, and architectural blockers that show up under load.

Shows what breaks at scale.

Architecture and design

Separation of concerns, modularity, coupling, boundaries, extensibility, and whether the system can evolve without heavy rework.

Connects structure to delivery speed.

Dependencies and licensing

Outdated packages, abandoned libraries, incompatible licenses, vulnerable dependencies, and hidden third-party liabilities.

Finds risk in plain sight.

Test coverage and quality

Unit, integration, and E2E coverage gaps, flaky suites, release confidence, and whether existing tests protect the business logic.

Reduces release anxiety.

Standards and compliance

HIPAA, PCI-DSS, SOC 2, GDPR, coding standards, documentation quality, and audit-readiness requirements where applicable.

Supports regulated decisions.

Executive scorecard

Translate technical findings into business decisions.

The audit output should not be a pile of tickets. It should show which findings affect security, release speed, operational risk, modernization, and product investment.

How the audit runs

Structured enough for leadership. Technical enough for engineering.

Sphere combines repository review, architecture interviews, automated checks, and senior engineering judgment into a clear delivery plan.

01

Scoping call

Align on goals, stack, risks, decision context, and deliverables in a focused kickoff.

02

NDA and access

Set up secure, read-only repository access under confidentiality before review begins.

03

Deep analysis

Senior engineers review code, architecture, dependencies, process, security, and operational signals.

04

Report delivery

Deliver a scored scorecard, findings summary, and prioritized remediation roadmap.

05

Consultation

Walk through the findings live with your lead auditor and align on next steps.

Audit packages

Choose the depth that matches the decision.

All audits are performed by senior engineers and scoped around the business question behind the review.

Why Sphere

Senior engineers. Not junior auditors.

Sphere auditors are seasoned developers who understand the underlying causes, business impact, and practical remediation paths behind codebase risk.

18+ years

Software development history behind the audit practice.

NDA first

Confidentiality and secure read-only access before code review begins.

Business alignment

Findings are tied to goals, not just technical metrics.

Actionable output

Scorecard, findings, roadmap, and post-audit consultation.

Questions before you start

Code audit, explained plainly.

CTOs, engineering leaders, business owners, PE firms, acquirers, and investors benefit when code quality, architecture, security, or modernization risk is material to a business decision.

No. Code audits are useful for legacy modernization, pre-release risk reviews, AI-assisted development quality checks, M&A technical due diligence, and teams that need to improve delivery speed.

A High-Level audit can deliver results in about 1 week. A Deep Dive audit is typically 4 weeks. Customized engagements are scoped individually and often run 4 weeks or longer.

Sphere can provide the audit as a standalone deliverable, or continue into a remediation sprint to address the highest-priority findings.

Sphere signs an NDA before accessing code, uses secure read-only repository access, does not modify your codebase, and delivers findings exclusively to your team.

Turn codebase uncertainty into a clear remediation plan.

Start with a code risk snapshot, a full technical audit, or a remediation sprint focused on the issues that matter most.
