Software audit services

We audit your software and give you a written report on every risk. In 7 days.

Security holes, slow queries, architectural debt, dependency exposure. Every finding rated Critical, High, Medium, or Low. Every fix explained. No verbal summaries. Report yours in 5 to 7 business days.

What happens next without an audit

Two teams. Same Tuesday. Very different nine months.

Security incidents, performance failures, and forced refactors all follow the same pattern. Every one of them was preventable. The difference is always the same: one team saw it coming.

Without an audit
MONTH 1
Unknown SQL injection vector in the auth layer
Nobody reviewed the authentication module in 14 months. The team rewrote it under deadline. It shipped. Nobody looked.
MONTH 4
Performance starts degrading. No one knows why.
The N+1 query pattern in the product catalog has run 800,000 queries this month. CDN cache is misconfigured. Load time up 3 seconds.
MONTH 7
Customer data exposed. The breach arrives.
The exact vector that a week-one audit would have flagged Critical. Remediation cost: $80k to $400k. That does not include regulatory fines or customer churn.
MONTH 9
Architectural refactor forced by accumulated debt
The tight coupling in the monolith cannot be worked around anymore. A $180k refactor was always coming. Now it happens under emergency conditions, not on a plan.
With a Redefine audit (week 1)
WEEK 1
SQL injection in auth module flagged as Critical
Finding 04 in the security section of the audit report. Severity: Critical. Estimated fix time: 4 hours. Remediation code included.
WEEK 2
N+1 query pattern and cache misconfiguration flagged
Performance section, findings 12 and 13. Your team fixes both in one sprint. Load time drops 3 seconds before the next feature ships.
MONTH 2
Architecture decoupling plan scoped and sequenced
The architecture section maps every tight dependency. A three-sprint refactor plan is scheduled before the monolith becomes a crisis.
MONTH 9 (SAME MONTH)
No incident. No emergency refactor. No breach.
The $80k incident became a $7k audit. The $180k emergency refactor became a planned sequence. The team ships new work instead of fixing old damage.

Three costs run every day your codebase goes unaudited.

Enter your annual revenue. The three meters show your real-time exposure: security breach risk, technical debt drain, and revenue lost to slow load times. Every number draws from published industry research.

What the audit covers

Four audit domains. Every check performed. Every finding in your report.

Select each domain to see which checks we run and what you receive in your audit report.

01
Security Review
23 checks
02
Architecture Assessment
18 checks
03
Performance Profiling
21 checks
04
Code Quality Analysis
16 checks
We check authentication and authorization logic, SQL injection entry points, cross-site scripting risks, API key and secret exposure in code, dependency vulnerabilities, session management, CSRF protection, and data encryption in transit and at rest. These are the most common vectors in real-world breaches.
Report section covers:
▸ Finding, severity rating (Critical/High/Medium/Low)
▸ Description of the risk this creates
▸ Remediation steps with example fix code
We map service dependencies and coupling, flag single points of failure, and identify what breaks first when traffic spikes 10x. We also review database schema design, API contracts, infrastructure layout, disaster recovery, and deployment pipeline risk.
Report section covers:
▸ Architecture diagram with risk annotations
▸ Scale ceiling: what breaks first at 10x
▸ Recommended refactoring sequence
We identify N+1 query patterns, missing database indexes, memory leaks, cache misconfiguration, large frontend bundles, and slow server response under realistic load. Each finding includes an estimated latency improvement so your team fixes in priority order.
Report section covers:
▸ Query count and timing on critical paths
▸ Estimated latency improvement per fix
▸ Priority order for maximum impact
We measure test coverage on critical code paths, flag duplication hotspots, review dependency version health, identify dead code, and score onboarding risk — how long a new engineer would need to understand your codebase. Poor onboarding scores signal future hiring and delivery cost.
Report section covers:
▸ Test coverage map by module
▸ Dependency vulnerability report
▸ Onboarding risk score

Client result

Shopify V2 migration: 14 security fixes before launch, 41% faster load time, zero downtime.

Security findings remediated
0
before migration began
We found and fixed 14 security issues before a single customer hit the new platform. Zero security incidents after launch.
Performance improvement
0
faster load time
N+1 queries and cache misconfiguration fixed before go-live. The site loaded 41% faster from day one.
Migration disruptions
0
downtime events
We mapped every compatibility risk before the cutover date. The migration went live without a single outage or disruption.

Ecommerce platformPre-migration audit

An ecommerce retailer needed to move from Shopify V1 to V2 without losing a day of revenue. We ran a full software audit before the migration started. The audit found security vulnerabilities in the checkout flow, N+1 query patterns in product collection pages, cache misconfiguration on high-traffic URLs, and compatibility gaps in custom JavaScript components.

Every security finding was fixed before cutover. Performance work was completed two weeks before launch. The migration went live with no downtime, no regressions, and no post-launch incidents. The new platform loaded 41% faster than V1 from the first day.

What sets a Redefine audit apart

A written report you can act on. Not a verbal summary you have to reconstruct.

📋

Written report, not a call

A written report is a roadmap your team uses for months. A verbal summary fades by Friday. Every finding is documented with severity rating, risk description, and remediation steps. Critical findings include example fix code.

🔧

Audit only, or audit plus fixes — your choice

You take the report to your own team. Or you scope a remediation sprint with us. Either works. The audit is never a hook for mandatory follow-on work. You are never required to hire us for fixes.

All development services →
📊

Severity ratings that explain the risk, not just label it

Every finding includes why it is Critical, High, Medium, or Low. A Critical finding explains what an attacker or a system failure could do with that exposure. Your engineering lead and your CTO read the same risk picture. Nobody translates for the room.

7 days. Fixed price. No billing surprises.

The price is fixed before we look at a single file. The report lands in 5 to 7 business days for standard codebases. If scope changes, you hear about it before the price changes. Not after.

Questions buyers ask us

What engineering leads and CTOs ask before they commit to a software audit.

A Redefine audit covers four domains: security review (23 checks including authentication, injection, and dependency exposure), architecture assessment (18 checks), performance profiling (21 checks), and code quality analysis (16 checks). Every finding gets a severity rating, a risk description, and a specific remediation step. Critical findings include example fix code.

Most audits are delivered in 5 to 7 business days. That covers a standard mid-sized application up to 150,000 lines of code. Larger codebases or those with compliance requirements — HIPAA, PCI, SOC 2 — take 10 to 14 business days. We confirm your exact timeline on the scoping call before any work starts.

Pricing depends on codebase size, number of services, compliance requirements, and how deep the audit goes. Most single-application audits run $4,000 to $12,000. You get a fixed price quote before we open a single file. No hourly billing. No surprise invoices. See the code audit services page for a full pricing breakdown.

You receive a written report with every finding organized by severity. Each finding includes what the risk is, what it could lead to, and exactly how to fix it. Critical findings include example fix code. The report is written for both engineers and non-technical decision-makers. You own it outright.

Yes, but only on request. After the audit, take the report to your own team or scope a remediation sprint with us. Both paths work. The audit is not a hook for follow-on work you did not ask for. If you choose remediation with us, we scope it as a separate fixed-price engagement based on your specific report findings.
