Vorpcel // Outbound Control

Extend security visibility
to the browser.

Outbound Control combines response inspection with browser telemetry to monitor script integrity, external data destinations and security configuration. Investigate changes with page-level context and manage response headers through the edge.

Client-side integrity

Inventory observed scripts, establish approved baselines and investigate content changes or suspicious script behavior.

Response security posture

Assess headers, cookies, CSP, CORS, mixed content and other response properties to identify configuration gaps.

Change monitoring

Compare observed data destinations and page resources with approved baselines to identify changes for investigation.

Manage the scripts your pages depend on.

Maintain an inventory of observed first-party and third-party scripts. Compare available content hashes with approved versions and review suspicious script patterns with the source and affected page in view.

Script visibility
Review observed scripts and their sources across monitored pages.
SHA-256 baseline & tamper detection
Compare observed content hashes with approved baselines to identify integrity changes.
Anti-skimming signatures
Identify script patterns associated with obfuscation, injection and suspicious access to payment fields.

Review outbound hosts and external page resources against your approved baseline. New destinations, scripts, frames and form targets provide signals for investigating unexpected third-party activity.

Outbound destinations
Review observed destinations for fetch, XHR, beacons and forms against approved hosts.
Response-surface drift
Investigate newly observed external scripts, frames and form targets as potential supply-chain changes.
Baseline you control
Approve expected destinations and page resources to establish a reference for future changes.

Identify gaps in response security.

Assess response properties against defined security checks. Findings identify missing or weak controls and the affected page or endpoint, helping teams plan configuration changes and follow up on remediation.

Headers & cookies
HSTS, nosniff, clickjacking protection, Referrer-Policy, Permissions-Policy, and cookie flags.
CSP, mixed content & SRI
Policy weaknesses, insecure http subresources, and cross-origin scripts loaded without integrity.
Header injection at the edge
Configure supported security headers and CSP for your applications and apply them to responses at the edge.

Score moves as your team resolves each finding.

Browser telemetry complements response inspection with observations of loaded resources and data destinations. Posture summaries and detailed findings help teams investigate changes and communicate remediation priorities.

Client-side telemetry
What loads and where data goes, observed from the browser itself.
One posture score, A to F
Use the posture grade and its underlying findings to track response security.
Context for investigation
Each finding carries its page, source and severity, ready to triage.
PCI DSS

Support payment-page security assessments.

Script inventories, approval records and change findings help support assessment activities related to PCI DSS 6.4.3 and 11.6.1. Use these records alongside your organization's control procedures and assessor-defined scope.

PCI DSS 6.4.3Evidence available

Evidence for script inventory, authorization and integrity review.

PCI DSS 11.6.1Evidence available

Evidence to support review of payment-page and response changes.
