system audit
Find out what your system is actually doing.
A comprehensive review of an existing application across maintainability, scalability, security, and performance — with findings written up for every audience from the engineer who has to fix it to the board that has to fund it, and a remediation plan that says what to do first.
when it is worth doing
You probably already suspect something.
An audit turns a suspicion into a specific, ranked, actionable list.
- Delivery has slowed down and nobody can point to a single cause
- You are about to raise, sell, or be acquired, and technical diligence is coming
- The original engineers have moved on and confidence went with them
- Incidents are recurring, and each fix seems to surface another
- You are planning a rewrite and want to know whether it is genuinely warranted
scope it
Four dimensions. Choose what matters to you.
Most engagements cover all four, because the findings interact — a performance problem is often a schema problem wearing a disguise. Narrow it if you already know where the pain is.
Your audit
Covering
- Maintainability
- Scalability
- Security
- Performance
Indicative only. The real range depends on system size, codebase age, and how much context already exists in documentation.
Request this auditwhat you receive
The same findings, written three times.
A stack trace does not help a board decide, and a risk summary does not help an engineer fix anything. Each audience gets the artefact it can actually act on.
Engineering
Technical findings report
- Every finding with file and line references
- Reproduction steps and supporting evidence
- Concrete remediation, not just a description of the problem
- Severity rated by exploitability and blast radius
Engineering leadership
Prioritised remediation plan
- Findings sequenced by risk against effort
- Dependencies between fixes, so work is not started in the wrong order
- Effort estimates in engineer-weeks
- What is safe to defer, stated explicitly
Executive
Risk and investment summary
- Current risk exposure in business terms, not stack traces
- What each class of finding could cost if it is left alone
- Recommended investment with a phased timeline
- A clear read on whether the system supports the next stage of growth
And then the part that matters
Remediation, not just diagnosis.
A list of problems is easy to produce and hard to use. Every audit ends with concrete remediation steps to get the application where your business needs it — sequenced, estimated, and specific enough that your team can start on Monday. If you would rather Null Vertex carried out the remediation, that becomes its own engagement.
