Our open web development security standard, TSS-WEB, has helped many organizations over the years defining their own set of requirements for this area. Since web development and its security aspects changes quickly, we’ve completely revised the standard and have also integrated OWASP SAMM v2.0, ISO/IEC 27002 and German IT-Grundschutz-Kompendium 2020 into it. TSS-WEB v2.0 is now available at https://tss-web.secodis.com, of course still under Creative Commons.
