Bridging the Security Gap.

Your marketing website needs to be fast, flexible, and SEO-optimized. Your banking portal needs to be an impenetrable fortress. Merging these two environments without creating user friction or compliance liabilities is the ultimate architectural challenge.

Explore The Architecture

The Integration Paradox

The Risk

Hosting authentication forms directly on a WordPress or open-source CMS exposes the login payload to thousands of third-party plugin vulnerabilities.

The Solution

Strict subdomain separation (`secure.bank.com`), headless APIs, and stateless JWT token handoffs that bypass the marketing server entirely.

The Core
Conflict.

Marketing teams want a website they can edit daily. Security teams want an infrastructure that never changes. When these teams collide, user experience suffers.

The Marketing CMS

Built for Agility
  • →

    Requires frequent updates for campaigns, rates, and SEO content.

  • →

    Relies on marketing pixels (Meta, Google) which are inherent security risks for sensitive data.

  • →

    Open to the public internet, optimized for fast indexing by search engine crawlers.

The Banking Core

Built for Security
  • →

    Legacy infrastructure (Fiserv, Jack Henry) that prioritizes stability over modern UI.

  • →

    Strictly prohibits any third-party tracking scripts or unverified code execution.

  • →

    Subject to stringent FINRA, FDIC, and PCI DSS compliance audits.

The Airgap Model

01
www.bank.com
The Marketing Site. Hosts the UI "Login" button. Contains no auth logic. Runs on public edge network.
02
SSO Provider / Auth0
The Identity Layer. Handles MFA, biometrics, and token generation independently.
03
secure.bank.com
The Application. Receives validated token. Marketing pixels stripped. Full access to Core banking API.

Architectural
Separation.

The golden rule of financial web architecture: Your marketing server should never touch a plaintext password.

We implement a strict subdomain segregation strategy. The marketing site (`www.bank.com`) acts solely as a brochure. When a user clicks "Log In", they are smoothly redirected to a dedicated, aggressively hardened application server (`secure.bank.com`) that handles the authentication handshake.

  • ✓

    Eliminates cross-site scripting (XSS) risks from marketing plugins.

  • ✓

    Keeps compliance auditors happy by dramatically reducing the audit scope.

Compliance
Boundaries.

Designing for the user is easy. Designing for the Federal Deposit Insurance Corporation (FDIC) requires precision.

PCI DSS Strict Scope

By abstracting the login portal away from the marketing CMS, you ensure that your lead generation website falls out of scope for burdensome Payment Card Industry Data Security Standard audits.

Pixel Contamination

We establish strict Content Security Policies (CSP) to ensure that aggressive tracking pixels (like the Meta Pixel) can never load or scrape data once the user crosses into the authenticated session state.

MFA Handshakes

Implementing seamless Multi-Factor Authentication (Biometric, SMS, Authenticator app) that triggers conditionally based on location anomalies, without booting the user back to the marketing homepage.

Maintaining
The Illusion.

While the backend architecture is heavily segregated, the end-user should never feel like they are jumping between two different companies.

From a UX perspective, we utilize shared CSS design tokens, persistent sub-navigation headers, and lightning-fast edge routing to ensure the transition from `www` to `secure` feels instant and visually cohesive, maintaining trust.

The Drop-off Danger

If a user clicks "Log In" and the page flashes, takes 4 seconds to load, and presents a completely different font and color scheme, trust plummets and support call volume spikes.

Establishing Encrypted Connection
🔒 256-Bit SSL Encryption • Bank-Grade Security

The Headless Future.

For modern fintechs and progressive credit unions, we deploy fully headless React/Next.js architectures where the frontend UI communicates directly with the Core banking APIs via secure middleware, completely eliminating legacy portal software.

const secureHandshake = async (payload) => {
const token = await authService.generateJWT(payload);
if (!token.isVerified) {
throw new AuthException('MFA Required');
}
return routeToSecureEnclave(token);
};
