Building Secure Web Applications

When we talk to clients about their digital goals, “security” often comes up with a mix of urgency and uncertainty. It’s one of those things everyone knows they need, but few know how to approach confidently. That’s where we come in—not with a one-size-fits-all solution, but with a shared commitment to doing it right, together.

Web application security is not a checklist. It’s an ongoing conversation between your team, our developers, and the ever-evolving digital landscape. Here’s how we approach it at Bloom—with transparency, craft, and empathy at the core.

Start With the Basics, But Don’t Stop There

The foundation of web application security starts with industry standards. Implementing HTTPS, sanitizing user input, and using secure authentication methods are no longer “nice to haves.” They are non-negotiables. According to OWASP, some of the most common vulnerabilities include injection flaws, broken access controls, and security misconfigurations. These aren’t rare edge cases, they’re issues we actively guard against in every project.

But meeting basic security requirements isn’t our finish line. We build beyond the basics because we know your users—and your business—deserve more than default settings.

Collaboration Is Key to Security

We believe in transparency not just in pricing or process, but in protection. “Security isn’t just about firewalls and passwords. It’s about shared responsibility,” as noted by Mozilla’s Web Security Guidelines. That means we involve you in our strategy conversations and code reviews. We’ll flag the risks. We’ll ask the hard questions. We’ll also make sure you understand what’s happening under the hood, because this isn’t just our job, it’s your site.

Design With Security in Mind

Our designers and developers work hand in hand from day one. This is where our craft-driven mindset really shows up. We don’t tack security onto the end of a build. It’s woven into every layout decision, every API call, every database schema.

We incorporate Content Security Policy (CSP) headers to guard against cross-site scripting (XSS). We adopt secure cookies and proper session management to reduce the risk of hijacking. And when we’re working with third-party services, we vet them just as thoroughly as we would our own code.

Keep Humans in the Loop

Even the best code can’t protect against a weak password or a phishing email. That’s why we always encourage clients to invest in training and awareness. If your team isn’t familiar with best practices, you’re leaving doors unlocked.

The National Institute of Standards and Technology (NIST) outlines strong identity proofing and authentication practices that we often reference. But we also explain these standards in plain language, because what’s secure should also be accessible to understand.

Ongoing Maintenance Is Part of the Partnership

Web application security doesn’t end at launch. We provide regular audits, dependency updates, and vulnerability scanning. More importantly, we stay in touch. “Security is a journey, not a destination,” as we like to say—and we’re here for the long haul.

We use tools like Snyk and Dependabot to proactively address risks in your dependencies. But we also prioritize human review. Automated tools help, but nothing replaces the sharp eye of a developer who knows your system inside and out.

Final Thoughts: We Don’t Know It All—And That’s Why We’re Good At This

There’s no single perfect solution to web application security. And we’re okay with that. What we offer is something better: a thoughtful, collaborative process where we work with you to protect what matters most.

We won’t pretend to have all the answers, but we’ll always ask the right questions. And we’ll keep showing up, checking in, and improving together—because building secure web applications is not just our job. It’s a shared responsibility.
