The firewall guards the request coming in. Outbound Control guards the response going out: script integrity, data leaving to third parties, and the hygiene of every response, inspected at the edge with no change to your application.
Know and pin every script that runs on your page, and catch tampering or skimmer behavior before a single card number leaves the browser.
Security headers, cookies, CSP, CORS, mixed content, SRI, redirects and exposed files, the objective checks that harden every response, including your API (JSON) responses, verified continuously.
Where data goes and how each page changes over time: exfiltration to new destinations and supply-chain drift, flagged the moment they appear.
Modern pages load code from many places, and any one of them can be the weak link. Outbound Control inventories every script and content-hashes it against the baseline you approved. When an approved script changes, or a known skimmer technique appears in one that executes, you know at once.
A breach shows itself when data starts flowing to a host that was never part of your application, or when a new external script or form quietly appears on a page. Outbound Control pins the destinations and the external surface of each page as a baseline, and flags anything new the moment it shows up.
A missing header or an insecure subresource is the kind of gap that never shows up until it is exploited. Outbound Control verifies the hygiene of every response against objective criteria, so the gaps surface before an attacker finds them, and each finding points to exactly what to fix.
Response posture
checkout.example.com
A lightweight agent runs in your visitors' browsers and reports what actually executes, while the edge inspects every response in parallel. Everything rolls up into a single posture score, so leadership sees one number and engineering sees the findings behind it.
Script management and change detection are exactly what payment-security requirements expect on a checkout page. Outbound Control keeps the record for you: the scripts running, their approval, and every change over time, ready to export. It maps directly to PCI DSS 6.4.3 and 11.6.1.
Management and integrity of every script on the payment page.
