PXL AUDIT TECHNICAL
An independent technical audit of your platform or project.
We review the code, architecture, infrastructure, basic security, observability and processes of your product. The deliverable is an actionable executive diagnosis.

What's included
A modular scope, set by urgency and the surface of the code
Source code review
Analysis of quality, maintainability, test coverage, accumulated technical debt and review practices.
Architecture audit
The current diagram, identification of bottlenecks, scalability risks and proposals for how it should evolve.
Infrastructure review
Cloud configuration, observability, backups, cloud costs, CI/CD and operational practice.
Basic security review
OWASP top 10, secret handling, authentication, authorisation and data exposure. For deep pentesting we complement this with PXL Security.
Team and process analysis
Real velocity, engineering practice, rituals, incident management and team satisfaction (where access is permitted).
Dependency and obsolescence analysis
Out-of-date libraries, known vulnerabilities (CVEs) and an update plan prioritised by risk.
Executive diagnosis
A 15 to 30 page document with findings classified by severity and impact, actionable at C-level.
Prioritised remediation plan
A roadmap with quick wins, structural improvements and deeper refactors, with an estimate of investment and time.
AI systems audit
We evaluate agents and models before and after they go into production: accuracy, hallucinations, bias, data leaks and resistance to manipulation. We deliver an assessment with prioritized risks.
Who it's for
Is PXL Audit Technical what you need?
We'll help you decide quickly. If we are not the right match,
we point you to who is.
This is not for you if…
- You need us to validate what you have already decided to do (that is consulting, not auditing)
- The project is very new (less than 4 months of code) and there is nothing significant to audit
- You are looking for specific predetermined conclusions (independent audits do not work that way)
- You cannot give access to the repository, the infrastructure or the documentation
This is for you if…
- You are about to invest significant capital in a product you did not build
- You have technical debt you cannot size and need to present it to the board
- You are going to buy or invest in a company and need technical due diligence
- Your product suffers frequent incidents and you cannot find the root cause
- You are changing supplier and need to know what you inherited before signing the handoff
- You hired a supplier who used pure AI with no judgement or technical supervision and you do not know what is inside your product
Problem
The price of deciding without seeing the code
Without an external audit, technical problems are described in the voice of the same team that created them. That almost always understates how serious they are. Internal teams can be normalised to the pain, founders can be caught in confirmation bias, and suppliers have every incentive to paint the state better than it is.
Technical investment decided on biased information
Buying a company where the technical debt multiplies the real cost
Acquired products that will not survive the next 18 months of roadmap
Teams that confuse 'it works' with 'it is well built'
Stack decisions taken without understanding the real constraints
Changes of supplier without knowing what is being inherited
Outcomes
Clarity to decide.
A well-made independent technical audit can save millions in decisions about investment, merger or product continuity. More importantly: it turns a conversation of 'I think something is wrong' into a conversation with data, severities and a plan of action.
Technical investment decisions made with data, not intuition
Robust due diligence for M&A or raising capital
A remediation plan prioritised by impact and cost
A clear conversation with the board and stakeholders about the real state
Early identification of risks before they turn into incidents
Independence from the current supplier, and freedom to decide
Process
The 5 steps of a typical engagement.
Scope and access
We define what will be audited (code, infrastructure, security, team) and secure the read-only access needed.
Technical analysis
A review of code, architecture, infrastructure, dependencies, observability and processes. Automated tooling plus senior manual review.
Interviews with the team
Sessions with technical leads, engineers and business stakeholders to validate findings and understand context.
Synthesis and prioritisation
Findings classified by severity, impact and cost of remediation. Quick wins identified separately.
Executive presentation
A 60 to 90 minute session with C-level and stakeholders to hand over the diagnosis and discuss the plan of action.

Frequently asked questions
What almost everyone asks.
Do you audit projects built mainly with AI?
Yes, it's one of the audits we're asked for most. We assess the quality of the generated code, the architecture, security, and future maintainability, regardless of whether the project was built with AI assistance, vibecoded, or in a traditional way.
How long does an audit take?
It depends on the size and complexity of the project being audited. In general, it typically takes 2 to 6 weeks. Reach out to us through Contact for a specific estimate.
What does it cost?
It depends on the size and complexity of the project. Reach out to us through Contact and we'll give you a clear quote based on scope.
Do we need to give you access to the code?
Yes, we need read access to the repository to run a real technical audit. We sign the necessary confidentiality agreements before starting.
Can you audit projects you did not build yourselves?
Yes, most of our audits are on projects built by other teams or providers. That's actually the most common case.
What happens after the audit?
You receive a report with findings prioritized by risk and impact. If you want, we can help you implement fixes through the corresponding service.
Do you also do deep security audits?
For security findings that require deeper analysis (a formal pentest), we do it together with PXL Security.
Do you also audit AI agents and models?
Yes. Beyond the code, we evaluate how they behave: how accurate their answers are, whether they hallucinate, leak information or can be manipulated. Ideally this happens before going to production and again whenever the model or data changes.
