PCI DSS: What You Need to Know as a Web Platform Owner

If your platform processes credit cards, PCI DSS compliance isn’t optional. And if you're running on legacy software? You're walking a compliance tightrope—whether you know it or not.

This guide doesn’t rehash the 12 PCI DSS 4.0 requirements—we’ve already done that in this full breakdown, including a blog post dedicated to each control. What this post does is speak directly to web platform owners navigating old systems, high stakes, and audit pressure with limited time and resources.

‍

What Web Platform Owners Are Up Against

PCI compliance is difficult with modern tooling. Add an outdated stack, and you're dealing with:

• No vendor security patches, creating immediate compliance gaps
  
  
• Lack of support for modern encryption standards and authentication protocols
  
  
• Incompatibility with centralized logging or SIEM solutions
  
  
• Internal resistance from devs who avoid touching fragile, legacy code
  
  
• Repeated audit issues with no clear long-term fix
  
  

And all of it sits on your shoulders—the one responsible for keeping the platform compliant without halting production.

Why It Matters Across Industries

Fintech

You operate in one of the most regulated and risk-sensitive industries. PCI compliance is the bare minimum to preserve partnerships with processors, banks, and third-party vendors. An unsupported framework or unpatched CVE could kill a key integration or trigger regulatory escalation.

E-Commerce

Every step of your checkout flow is in PCI scope. From storing billing profiles to handling transactions, your frontend and backend both need to meet the standard. If your CMS or JavaScript framework is EOL and unpatched, you're exposed and may not even know it—until a breach happens or a scan fails.

Healthcare

Even if you’re HIPAA-compliant, you can’t ignore PCI. If your system handles billing, patient payment portals, or insurance copays, then cardholder data is in play. The compliance load is heavier, and the risks are amplified. A single compromise could violate both HIPAA and PCI simultaneously.

Real Pain Points from Real Platforms

1. Vulnerability scans keep flagging critical issues
Legacy platforms often contain dependencies with known CVEs that can’t be fixed with official patches—because support has ended. That leaves you with two options: maintain it in-house or accept noncompliance.

2. You rely on compensating controls to pass audits
It’s a stopgap. You spend time writing documentation, negotiating exceptions with auditors, and building fragile workarounds just to stay operational. But compensating controls aren’t scalable, and they’re increasingly scrutinized under PCI DSS 4.0.

3. Your team avoids the codebase
Nobody wants to touch your ancient framework, and even fewer are comfortable modifying it for security purposes. That slows response time, increases mistakes, and stalls essential updates.

4. Security updates are reactive, not proactive
You’re always playing catch-up—responding to CVEs, scrambling before audits, or locking down systems after something breaks. You can't afford to live in emergency mode, but you don’t have the resources to migrate either.

Why "Just Upgrade It" Isn't Always Feasible

Replatforming will always be the goal. But in reality:

• It can take 6–18 months
  
  
• Involves complex data migration, testing, and staff retraining
  
  
• Risks breaking core business logic or integrations
  
  
• Costs far more than your current budget allows
  
  
• Creates new compliance risks during the transition
  
  

Most platform owners can’t afford to rebuild just to check a compliance box. You need a bridge between now and a future migration.

The HeroDevs Solution: Never-Ending Support for Legacy Software

HeroDevs provides Never-Ending Support (NES) for end-of-life open-source frameworks, libraries, and runtimes. We offer:

• Ongoing security patches for unsupported software
  
  
• Compliance-ready builds designed to meet PCI, HIPAA, SOC 2, and FedRAMP standards
  
  
• Drop-in replacements—no refactoring required
  
  
• Compatibility updates for modern browsers, operating systems, and environments
  
  
• Documentation you can hand directly to your auditors
  
  

It’s not a workaround—it’s a vendor-backed solution with real SLAs and real security coverage.

‍

What It Looks Like in Practice

Let’s say your platform still runs AngularJS. You’re compliant today, but a new vulnerability is disclosed tomorrow.

Without HeroDevs:
You’re exposed. There’s no patch. You scramble to patch it yourself or create compensating controls. Audit day becomes a minefield.

With HeroDevs:
The patch is already available. You swap the updated dependency. Your compliance is intact. Audit documentation is handled. Your team doesn’t waste a sprint fighting fires.

‍

NES Supports What You’re Already Running

Current HeroDevs NES offerings include support for:

• AngularJS
  
  
• Vue 2
  
  
• Node.js 12 & 14
  
  
• Apache Tomcat
  
  
• .NET Framework
  
  
• And more
  
  

If your platform depends on any of these, NES lets you keep moving forward—without breaking compliance or momentum.

Final Word: Compliance Without Chaos

As a web platform owner, PCI DSS compliance isn’t just a checklist—it’s an operational reality. And if your system is built on legacy code, the stakes are even higher.

You don’t need to migrate today if it interupts your business needs.
You don’t need to rebuild everything.
You do need a secure, supportable path that keeps your platform compliant now—and keeps your auditors off your back later.

HeroDevs Never-Ending Support is that path.

Stay secure. Stay compliant. Keep what works. Let us handle the rest.
