AI Can Build Your App. It Won’t Secure It.
AI coding assistants and “vibe coding” have dramatically lowered the barrier to building software. Today, almost anyone can generate a web application, deploy it in minutes, and iterate faster than ever before.
However, one challenge remains largely unchanged: security.
As privacy regulations and data protection laws continue to evolve across the world, shipping a secure application is no longer optional. Whether you’re building a side project or a SaaS product, security should be considered from the very first commit—not after your first incident.
In this article, I’ll share some practical lessons we’ve learned while deploying production applications.
1. Start with secure code
Before your application ever reaches production, ask yourself a simple question:
Has my code actually been reviewed for security?
Modern CI/CD pipelines should include automated security checks such as:
- OWASP ZAP for Dynamic Application Security Testing (DAST)
- Static Application Security Testing (SAST) tools
- Dependency and vulnerability scanners
- Secret detection to prevent API keys and credentials from being committed
Finding these issues before deployment is significantly cheaper than fixing them after an attack.
2. Keep secrets out of your repository
One of the most common mistakes in young projects is storing secrets directly inside the repository.
Imagine onboarding a new developer. They should be able to clone your project and start working using their own configuration, without ever receiving production credentials.
Good practices include:
- Using environment variables
- Using a secrets manager
- Rotating compromised credentials immediately
- Never committing API keys, database passwords or cloud credentials
A clean repository makes collaboration safer and deployment easier.
3. Choose the right deployment platform
The deployment model you choose has a huge impact on your operational security.
If you use managed platforms such as Cloud Run, Heroku or other serverless providers, much of the infrastructure maintenance is handled for you.
If you prefer managing your own infrastructure, Platform-as-a-Service (PaaS) solutions like Dokploy or CapRover provide an excellent balance between flexibility and ease of deployment while keeping you in control of your servers.
The important question isn’t which platform is “best”, but whether you’re prepared to secure the infrastructure you’re responsible for.
4. Protect your application after deployment
Deployment is only the beginning.
Like many teams, we initially relied on Cloudflare for protection. While it provides excellent features, we found that some advanced security capabilities were locked behind higher-priced plans.
As an alternative, we implemented CrowdSec on our own infrastructure.
CrowdSec analyses logs from your services and collaborates with a community-driven threat intelligence network to identify and block malicious IP addresses, brute-force attempts and abusive bots.
For self-hosted environments, it’s an excellent addition to your security stack.
5. Monitor and respond to attacks
Once CrowdSec was deployed, we started seeing something interesting.
A significant amount of unwanted traffic originated from a small number of regions where scraping and automated scanning were particularly aggressive. While it’s important not to make assumptions based solely on geography, monitoring attack patterns allowed us to apply additional protections where appropriate.
Security isn’t only about blocking traffic—it’s about understanding what is happening on your infrastructure.
6. Improve visibility
One limitation of many self-hosted security tools is the user experience.
Fortunately, the community has created several modern dashboards that make managing CrowdSec much easier.
If you’re running multiple servers, a central interface greatly simplifies monitoring decisions, remediation and day-to-day administration.
Final thoughts
AI has made building applications incredibly fast.
Unfortunately, attackers are using AI as well.
The difference between a successful application and a compromised one often comes down to the practices you adopt before and after deployment.
Security is not a product you install once—it’s a continuous process.
If you’re deploying your own applications, start with automated security testing, keep your secrets out of your repository, choose an infrastructure you can confidently manage, and monitor your systems continuously.
Building software has never been easier.
Building secure software is still a discipline.
At HOMESCRIPT, we help businesses build secure applications from day one. By integrating security into the development lifecycle—from architecture and automated testing to deployment and monitoring—we help teams anticipate risks before they become costly production issues. If you’re planning a new project or want to strengthen the security of an existing one, we’d be happy to help. Get in touch with us through our contact page: HOMESCRIPT CONTACT
