Part of our ongoing Guide to Penetration Testing
With easier access to AI tools and a flood of "vibe coded" apps hitting the market, vulnerable applications are becoming more and more common. This doesn't just put you, the creator, on the line. It puts every single person who trusts you and uses your app at risk too.
A poorly secured AI-built application can lead to personal credential leaks, dumped passwords, and, most costly of all, exposed API keys. These are the three biggest risk outcomes we see. Newer models like GLM-5.2 and Anthropic's Claude models are genuinely brilliant, but they are not perfect, and they were never designed to be your security team.
The only way to be fully confident in the security of an app, site, or anything else you've vibe coded is to understand, to at least a foundational technical level, what you're actually building. That gap in understanding is, sadly, what causes most of these issues in the first place. Vibe coding tools are excellent at producing something that works. They are far less reliable at producing something that's safe.
"What if I can't be bothered learning it, but I still want to be secure?"
This is the question a lot of founders and solo vibe coders land on eventually. The short answer: you need a security assessment or a penetration test, depending on what exactly you're building.
The good news is there are plenty of budget-friendly options out there, so you can get peace of mind without going bankrupt in the process.
Aussie Pentest offers Automated Penetration Testing, which is significantly cheaper than traditional manual penetration testing while still delivering a lightning-fast turnaround time of 24 to 72 hours.
Most people don't actually know what they need
Here's where a lot of founders get stuck before they've even started: there's no single "penetration test" that covers everything, and picking the wrong type wastes both time and money.
- ▸A vibe-coded MVP or side project with no sensitive user data usually just needs an automated security assessment. It's fast, affordable, and catches the common mistakes that vibe coding tends to introduce, like exposed API keys, misconfigured storage buckets, and weak authentication.
- ▸An app handling real user data, like logins, personal details, or payment information, needs a proper penetration test. This goes deeper than automated scanning and looks for logic flaws, broken access controls, and the kind of issues a scanner alone will miss.
- ▸An app targeting enterprise or government clients will often need to meet a recognised standard, such as Essential Eight, before anyone will sign a contract with you. This is less about finding every possible bug and more about proving, on paper, that you take security seriously.
If you're not sure which of these describes your app, that's completely normal. It's exactly the kind of question a quick chat with a security team should answer for you, before you spend a cent.
The real cost of skipping this step
A breach doesn't just cost money to fix. It costs trust, and trust is far harder to rebuild than code. For an early-stage app, a single leaked API key or an exposed database can be enough to end things before they've really begun, whether that's through direct financial loss, a regulatory headache, or simply losing users who no longer feel safe on your platform.
Compared to that, the cost of a pentest is small. Think of it less as an expense and more as insurance for the thing you've spent months building.
Don't launch blind
If you've vibe coded your way to a working product, that's genuinely impressive, and it's a real achievement. But "working" and "secure" are two different things, and the gap between them is exactly where most breaches happen.
Before you launch, get a proper look under the hood. Book an Automated Penetration Test with Aussie Pentest and find out where your app actually stands, before someone else does.
