Ship Security Fixes in Days, Not Weeks
AI now finds software flaws faster than most organisations can fix them. We help banks and fintechs upgrade old systems, test every change and release fixes safely and fast.
Finding Flaws Got Cheap. Fixing Them Is the Hard Part.
AI models now find serious flaws in software faster than most teams can fix them. Attackers use the same tools. What decides whether a bank or fintech gets hurt is how fast it can ship a fix it trusts.
That speed comes from engineering: knowing what runs where, tests around the paths that move money, release pipelines that ship a fix with the same checks in days and old systems moved onto versions that still get security fixes. That is the work we do.
Challenges We Solve
- ✕
Core systems on versions that no longer get security fixes
✓We upgrade them in small, tested steps. Tests go around the paths that move money first and every step is easy to undo.
- ✕
A critical fix waits weeks for the next change window
✓We build a fast lane through your release pipeline: the same tests and checks, a gradual rollout and a rehearsed rollback. A security fix can then go live in days.
- ✕
Nobody can say for sure which servers run what
✓We help you build an inventory that updates itself from your systems. When the next critical flaw lands you know where to look straight away.
- ✕
Patches marked done that never reached the live servers
✓We check every fix from the outside: which server, which build, serving which site. A patch isn't done until it's verified.
What We Build for Banks and Fintechs
Legacy Upgrades
Old frameworks and language versions such as PHP 7 moved onto supported releases in small, tested steps.
Automated Tests
Tests around logins, payments and statements first. Every change is checked before it ships.
Patching & Verification
Security fixes applied, then checked from the outside on the servers that actually serve your traffic.
Monitoring & Recovery
Alerts on what matters, backups you've actually restored and a rehearsed plan for the bad day.
Who You'll Work With
Zunderdog's founder, Zubin Souza, spent a major chunk of his career on banking and payment systems. He worked on State Bank of India's core banking system as an engineer at TCS, then spent five years on eBay and PayPal's architecture team.
He has been talking to major banks about what has to change now that AI finds flaws faster than teams can fix them. You speak with him before anything is signed.
How We Help
Here's how we help banks and fintechs ship fixes faster without cutting corners.
How We Work
Before we dive in, we'll work closely with you to understand your project goals, target audience and desired functionalities. This ensures we're on the same page from the start.
Our design team utilizes cutting-edge tools to craft user interfaces (UI) that are both aesthetically pleasing and intuitive. We prioritize a user-friendly experience (UX) to keep your audience engaged.
After solidifying the design, we'll create an interactive prototype that allows you to visualize and interact with the future product. This provides valuable feedback before development begins.
We leverage the latest technologies and tools to build your mobile app or website. Transparency is key, so you'll be kept in the loop throughout the development process.
Quality is non-negotiable. Our dedicated QA team rigorously tests every aspect of your project to ensure it's bug-free and delivers a flawless experience.
Once everything is tested and perfected, we'll guide you through a smooth launch process, getting your product in front of your target audience.
Our commitment extends beyond launch. We offer ongoing support and maintenance to ensure your project continues to function flawlessly and our team is always ready to answer your questions.
Frequently Asked Questions
No. We are a software company. Security teams find and rank the risks. We do the engineering that fixes them: upgrades, tests, release pipelines and patching, alongside your team and your vendors.
Yes, where your contract and the vendor allow it. Where only the vendor can change the code, we work with them on the upgrade plan and the tests.
That depends on your tests and pipeline today. The aim is days for a critical fix, with the same checks as any other release. We start by finding what slows a fix down and remove that first.
Yes. Fintechs often have newer code and fewer approvals. They still run on the same open-source building blocks and get hit by the same flaws. The work is the same: know what you run, test it and ship fixes fast.
