Secure Web Development
Websites and web applications built secure from the first line of code.
Most web applications are built for features first and secured later, if at all. We design, build, analyze and customize websites and web applications with security built in from the start: threat modeling, secure coding, code review and testing at every release, so what you launch doesn't become your weakest link.
Who this is for
Built for organizations like yours
Organizations Launching Something New
A website, customer portal or internal web application that has to be secure and dependable from day one.
Teams With an Existing Application
Applications that grew quickly and now need an honest analysis of their code, architecture and security.
Businesses Running Off-the-Shelf Platforms
CMS, e-commerce and SaaS platforms that need customizations, extensions or integrations done safely.
The problem
Risks we address
Vulnerable web applications
Injection, broken access control and misconfigurations that expose customer data through the website itself.
Risky customizations
Plugins, scripts and quick fixes added without review that open holes in an otherwise secure platform.
Code nobody fully understands
Applications with outdated dependencies, missing documentation and no clear picture of how data flows.

FAQ
Common questions
Do you only build security software?
No. We build general websites and web applications too. The difference is that every project is designed, coded and tested with security in mind.
Can you analyze or customize an application someone else built?
Yes. We review existing code and platforms, explain what we find in plain language, and can take on customizations, fixes and ongoing maintenance.
Who owns the code?
You do. Custom code is delivered with its source and documentation.
