The first WordPress security plugin that protects your frontend even when it's on a different domain. Wordfence, Sucuri, MalCare, Patchstack - they all only run on the PHP server. When your frontend is React on Vercel or a static site on Cloudflare Pages, they're blind. Shield closes that gap.
WordPress security plugins run on the server. They scan PHP files, monitor the database, block malicious requests. But when WordPress is a headless CMS and the frontend lives on a separate domain, the server-side plugin has zero visibility into what's happening in the browser.
A compromised third-party script. A supply-chain attack on an npm package. A Magecart skimmer injected via a CDN. A DOM XSS payload in a URL parameter. All of these happen in the browser, on your frontend, after the page leaves WordPress. No PHP plugin can see them.
Nova Shield can.
Your visitors run the Shield agent. When an attacker injects a malicious script, the next visitor who loads the page detects it and reports it back to WordPress. The attacker's browser settings are irrelevant.
