About Us

Why?

Content Security Policy is known to be difficult. But so are lots of topics. We believe that any topic can be made easier when presented in the right way.

So we built a tool to make Content Security Policy easier for all.

Csper was built out of frustrations.

  • Frustrated at the existing 'feel-good' security tools and documentation. The tools and documentation that will give you an A+ rating even though the policy is providing no security value.
  • Frustrated that even after years of CSP being released, it's still difficult for non-security-experts get started with Content Security Policy.
  • And frustrated that although many CSP tools were being built, but they weren't solving the real challenges that users face (the challenges I faced when deploying CSP on a real website).

Stuart Larsen Founder

Stuart started programming when he was a kid to build (and sometimes cheat) at video games.

He went on to do more useful programming and eventually became a security engineer at a variety of companies.

After being tired of the difficulties and lack of tooling for CSP he founded Csper.

In his free time he plays CTFs and uploads writeups to Youtube (Sloppy Joe Pirates).
