The most useful software audit is the one that tells you what you do not want to hear, before it becomes expensive. We produce that audit.
Independent engineering assessment of risk, debt, and delivery capability.
BNS delivers structured software audits that give leadership, investors, and acquirers an honest engineering picture — code quality, architecture risk, security posture, and delivery capability assessed by principals who have seen comparable programs.
BNS software audits provide an independent engineering assessment for leadership decisions, M&A transactions, vendor evaluations, and strategic program reviews. The worst software audits confirm what the sponsor already believes. The most valuable ones surface what the delivery team cannot say to the business, or has stopped noticing. Our audit principals assess code quality, architecture risk, security posture, delivery capability, and total cost of ownership — and produce findings packs that a CTO, CFO, and board can all act on.
Our audit scope covers the full engineering system — not just the code. Architecture decisions, delivery practices, observability, test coverage, dependency risk, and team capability are all in scope. Every audit ends with a risk-prioritised findings pack, a remediation roadmap, and an honest cost-to-fix model. If the findings require a remediation program, our quality engineering practice and application development team provide a continuous path from audit to improvement.
Define audit objectives, access requirements, and the decision the findings must inform.
Code analysis, architecture review, security scan, delivery metrics, and stakeholder interviews.
Risk-prioritised findings with evidence, root cause, and cost-to-fix for each.
Sequenced remediation roadmap with effort estimates and a business case for the investment.
Technical debt quantification, code health metrics, and maintainability risk across the production codebase.
Structural risk, coupling analysis, scalability constraints, and architectural decision quality.
OWASP Top 10, dependency CVEs, secrets management, and infrastructure security controls.
DORA metrics, CI/CD maturity, test coverage, deployment risk, and release predictability.
Third-party dependency risk, licence exposure, SBOM, and end-of-life software inventory.
Risk-prioritised findings with effort estimates, cost-to-fix model, and sequenced remediation plan.
BNS is technology-neutral by policy — our engineers work across the open-source and commercial stacks that enterprise platforms actually run on.
Independent audit gives leadership the engineering truth that internal teams are sometimes positioned to soften or defer. BNS audit findings are written for the decision-maker, not the delivery team — with risk quantified, evidence cited, and recommendations that are actionable.
Technical due diligence for acquisition or investment requires the depth to read the code and the experience to interpret what it means commercially. BNS audit principals have assessed comparable systems and know the difference between fixable debt and architectural risk that reprices the deal.
Software audits surface OWASP Top 10, dependency CVEs, secrets management failures, and infrastructure security control gaps before a penetration test or regulatory examination does. The cost of a finding inside an audit is the remediation; the cost outside an audit is the incident.
Risk-prioritised findings with effort estimates and sequencing give the delivery team a backlog they can defend to the business — not a list of problems without a plan. The audit ends with a cost-to-fix model that the CFO can use to fund the remediation.
The code is only part of the risk. DORA metrics, CI/CD maturity, test coverage, and deployment risk are assessed alongside code quality — because a high-quality codebase with a broken delivery process is still a risk to the next release.
Our audit leads have built, run, and modernised the platforms they assess. The risk assessment reflects production reality — not the findings a static analysis tool produces without context.
BNS audit reports are written for a CTO, a CFO, and a board member to read in the same sitting. Technical findings are translated into delivery risk, cost risk, and strategic risk without losing the engineering precision that makes them credible.
Software audits across finance, healthcare, energy, logistics, and the public sector — with experience of the regulatory requirements, audit standards, and evidence expectations that apply in each.
Client code, architecture, and production data accessed during the audit are handled under ISO 27001 and SOC 2 Type II controls. Audit access is scoped, logged, and revoked on engagement close.
Measurable outcomes from the platforms our engineers shipped this year.
The organisations that land zero-trust treat it as a product with a roadmap, SLAs, and consumer teams — not a two-year migration project.
Quality engineering is not a department. It is the operating system that decides how quickly leadership can green-light a release.
Why fixed-price is rarely the right answer, outcome-based contracts are harder than you think, and the model that wins is neither.
Two to three weeks for a standard product audit. Large enterprise codebases with multiple systems run three to four weeks.
Yes — we can run quarterly or annual audits as part of a continuous assurance program.
Continuous quality that gives leadership confidence to ship faster.
Custom business applications engineered for the load, risk and scale of your organisation.
Engineering-grade security: embedded into the platform, not bolted on top.
