Accelerating PCI DSS Readiness for a Modern Payments Platform

The Challenge

As a fast-growing payments platform, Pulse needed to achieve PCI DSS readiness without slowing down product velocity. Cardholder data touched more systems than the team realized, scope boundaries were unclear, and previous attempts to map compliance requirements had stalled out amid competing engineering priorities. Leadership needed a clear, achievable path to compliance that wouldn't require freezing the roadmap for months.

The Solution

ControlSage partnered with Pulse to build a precise map of its cardholder data environment, tracing exactly where card data was stored, processed, and transmitted across the platform. That exercise surfaced several opportunities to reduce scope entirely, including moving toward tokenization and shifting more processing to already-validated third-party providers rather than building additional compliance obligations in-house.

With scope clarified and reduced, we worked with Pulse's engineering team to implement the remaining required controls, from network segmentation to access management, in a sequence that fit around existing sprint cycles rather than disrupting them. We also prepared the team for its formal assessment, coordinating directly with their QSA and managing evidence requests so engineering could stay focused on shipping.

The Results

Pulse moved through its PCI DSS engagement with far less disruption than the team had originally expected:

• Meaningfully reduced cardholder data environment scope

• Faster path to compliant status than initially projected

• Lower ongoing burden for future annual assessments

• Minimal disruption to the product development roadmap

• A defensible, well-documented control environment

Client Testimonial

"ControlSage helped us build a stronger compliance foundation with practical, scalable security guidance."

Key Outcomes

By reducing scope before adding controls, Pulse reached PCI DSS compliance faster and with a smaller ongoing footprint than a traditional approach would have required. The engineering team kept shipping throughout the engagement, and future assessments are now materially lighter thanks to the scope reduction work done up front. Compliance became a one-time investment with a long-term payoff rather than a recurring drag on the roadmap.
