It contains a number of points that experts consider the most critical security risks for web applications. By following these principles, along with a checklist based on Certified Secure methods, we can systematically prevent common errors.<\/p>\n\n\n\n<p>Within the overall development process, the four-eyes principle provides an additional guarantee of quality and reliability. This principle means that critical actions, such as code changes or production deployments, are always reviewed by at least two authorized individuals. In addition to the four-eyes principle, each release is also manually tested in our acceptance environment.<\/p>\n<\/div>\n\n    <\/div>\n    <\/section>\n\n\n<section \n        class=\"wp-block-theme-consult  \">\n    \n            <div class=\"wp-block-theme-consult__inner\">\n                            <div class=\"card-staff\">\n                <figure class=\"card-staff__avatar\">\n            <img decoding=\"async\" data-src=\"https:\/\/www.yellenge.nl\/wp-content\/uploads\/2025\/04\/team-2024_12_02_YELLENGE_PORTRETTEN_KarinJonkers_004-8-68x68-c-default.jpg\"\n                 data-srcset=\"https:\/\/www.yellenge.nl\/wp-content\/uploads\/2025\/04\/team-2024_12_02_YELLENGE_PORTRETTEN_KarinJonkers_004-8-68x68-c-default.jpg 1x, https:\/\/www.yellenge.nl\/wp-content\/uploads\/2025\/04\/team-2024_12_02_YELLENGE_PORTRETTEN_KarinJonkers_004-8-102x102-c-default.jpg 1.5x, https:\/\/www.yellenge.nl\/wp-content\/uploads\/2025\/04\/team-2024_12_02_YELLENGE_PORTRETTEN_KarinJonkers_004-8-136x136-c-default.jpg 2x,\"\n                 alt=\"Yellenge medewerker\"\n                 class=\"wp-image-1018 lazyload\" width=\"68\" height=\"68\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 68px; --smush-placeholder-aspect-ratio: 68\/68;\">\n        <\/figure>\n        <span class=\"card-staff__name\">Rik van der Velden<\/span>\n    <span class=\"card-staff__info\">Security Officer &#038; Test Engineer<\/span>\n<\/div>\n\n            \n                                                                <a href=\"https:\/\/www.yellenge.nl\/contact\/\" class='wp-block-theme-consult__link' target='_self'>                    <div data-anim-rotate>\n                        <div>Contact us<\/div>\n                    <\/div>\n                <\/a>\n    \n                    <\/div>\n    <\/section>\n\n","protected":false},"excerpt":{"rendered":"<p>ISO 27001 Certification Yellenge has been ISO 27001 certified since 2019.
