Pixel Pushing vs DOM rendering: what's the difference?

Pixel Pushing vs DOM rendering: what's the difference?

At the heart of Remote Browser Isolation (RBI) technology are two distinct rendering methods: Pixel Pushing and DOM Isolation.

While serving the same overall purpose of isolating the browser from the user environment to enhance security, these approaches fundamentally differ in how they work and what their implications are. Given the significant growth of cybersecurity in today's digital landscape, it is critical for businesses to fully understand these methods. In this article, we compare these two approaches according to key criteria in order to help inform your technological choice.

Pixel Pushing vs DOM Isolation

Critères Pixel Pushing DOM Isolation
Sécurité Totalement isolé avec rendu serveur, zéro contenu actif envoyé à l'utilisateur, offrant une isolation robuste. Purification du DOM, dépend de la précision de l'analyse. Risque de non détection de certains contenus malveillants.
Transparence Utilisateur Expérience utilisateur uniforme mais possible latence en fonction de bande passante de l'utilisateur. Expérience quasi native, mais des éléments peuvent ne pas se rendre correctement.
Scalabilité Extensible avec des ressources supplémentaires, mais augmentation de charge avec de nombreux utilisateurs. Moins gourmand en ressources, mais sites web lourds peuvent nécessiter plus de ressources.

Unlike most traditional RBI solutions that rely on reconstructing the Document Object Model (DOM) within the local browser, with a residual risk of malicious code execution, Pixel Pushing rendering technology offers a more secure approach. All of the code — whether it's HTML, CSS, JavaScript, JavaScript, JavaScript, Cookies, or even document viewing — is executed in a remote environment, isolated from the user's local network. The final result is then transmitted in the form of a video stream offering a significant advantage in terms of security and user transparency.
