Application Security Services

Your software is only as secure as its last test. Arvo’s application security services give businesses a clear picture of where their systems are exposed and what needs to be fixed – before those gaps become incidents.

Who this service is for

This service is built for businesses that have a web application, internal system, or custom-built software and want to know how it holds up under scrutiny. That includes:

SMBs and startups that have built or commissioned a custom web application and need independent validation before launch or after significant changes

Government bodies and publicly listed companies with compliance obligations or procurement requirements around security assurance – Arvo holds Local Buy prequalification under the Queensland Government’s procurement framework

Businesses handing off to a new development team and wanting a baseline security assessment before work continues

Organisations that have had an incident, a near-miss, or an external audit recommendation and need to act on it

If your software handles sensitive data, financial transactions, personal information, or government records, this is not optional work. It is the kind of assessment that should happen before production, not after a breach.

What a software security audit covers

Arvo’s security audits are assessments of your software system – how it is built, how it handles data, where access controls are implemented, and where they are not.

The scope varies based on the system, but a typical engagement covers:

  • Authentication and authorisation vulnerabilities (who can access what, and whether that access is actually enforced)
  • Input validation and injection risks (SQL injection, XSS, and related attack vectors)
  • API security (endpoints, authentication tokens, exposed data)
  • Session management and credential handling
  • Data exposure risks at the application layer
  • Dependencies and third-party library vulnerabilities

At the end of the engagement, you receive a written report detailing what was found, how serious each finding is, and what remediation looks like. The goal is not a pass/fail score – it is a clear, prioritised list of what to fix and in what order.

How it works

Scoping

Every engagement starts with a scoping conversation. We need to understand what the system does, how it is built, what data it handles, and what your specific concerns are. This determines the depth and focus of the assessment.

Assessment

Our team works through the application systematically, testing for known vulnerability classes and looking for issues specific to your system’s architecture and implementation. Testing can be conducted as black-box (no prior access or code), grey-box (partial access, mimicking a credentialed attacker), or white-box (full code and architecture access), depending on what is most useful for your context.

Reporting

You receive a detailed written report covering every finding, its severity, and practical remediation guidance. We do not produce reports full of technical jargon and leave you to figure out the rest – findings are written so your development team can act on them directly.

Follow-up

If you need help interpreting findings or want Arvo to oversee remediation through our systems and software development team, that is an option. Security assessments and development work sit under the same roof, which means you are not managing two separate vendors across the same problem.

Why work with Arvo on application security

Arvo is a full-service digital agency, which means application security sits alongside web development, cloud hosting, and managed IT – not as a standalone service from a specialist firm with no visibility into how the rest of your digital environment is built.

That matters in practice. When our security team identifies a vulnerability at the application layer and the recommended fix involves your hosting environment or your deployment process, we can connect those dots directly. You are not receiving a security report that then requires a second engagement with a different team to implement.

For businesses operating in or supplying to the Queensland Government, Arvo is a prequalified supplier under the Local Buy framework. This simplifies procurement and means engagements can move faster than they would with a provider that has not been through the accreditation process.

Frequently Asked Questions

What is the difference between application security testing and a security audit?

Application security testing refers to the active process of probing a system for vulnerabilities – running tools, manual checks, and exploit simulations against the application. A security audit is the broader engagement: it includes testing, but also covers documentation review, access control policies, dependency analysis, and a formal written report. Most businesses that ask for one actually need the other, or both. Arvo’s engagements cover the full scope.

Do you test web applications only, or other software systems too?

Web applications are the most common scope, but Arvo’s software security assessments can cover APIs, internal business systems, and custom-built software regardless of whether it is publicly accessible. Scope is confirmed during the initial conversation.

How long does a security assessment take?

It depends on the complexity and size of the system being assessed. A focused web application assessment for a small or medium system typically takes one to two weeks from scoping to report delivery. Larger or more complex engagements take longer. We will give you a realistic timeline during scoping, not an optimistic one.

Will the testing affect our live system?

This is confirmed during scoping. Most assessments are conducted against a staging or test environment to avoid any impact on production. Where testing must be done against a live system, timing is agreed in advance and activities that carry disruption risk are either excluded or scheduled for low-traffic periods.

We have already had a penetration test done. Do we need a security audit too?

A penetration test and a software security audit are not the same thing. A penetration test focuses on whether an attacker can get in. A security audit focuses on why they might be able to, and what the systemic issues are that create that risk. If you have a pen test report with findings that were not fully remediated, or if the test was done more than 12 months ago, an audit is a reasonable next step.

Is Arvo able to support government procurement processes?

Yes. Arvo is a prequalified supplier under the Queensland Government’s Local Buy framework, which streamlines procurement for government agencies and bodies that use that framework. Contact us directly to discuss your procurement requirements.

Get an application security assessment

If you have a software system that has not been independently assessed, or if you have findings from a previous audit or test that need to be acted on, the next step is a scoping conversation.
