Zero to PCI DSS Level 1 in 90 Days: Justt's Fast Track to Processing Enterprise Data
Most companies treat a PCI DSS Level 1 ROC as a year-long grind. Justt, a fast-growing fintech reinventing chargeback management, didn't have a year, it needed to serve enterprise clients with stringent security requirements now. Here's how GRSee turned one of the industry's toughest certifications into a 3-month sprint, without cutting a single corner.

THE CHALLENGE
Justt is a rapidly growing fintech that became the market leading chargeback mitigation solution globally by pioneering an innovative Machine Learning approach while the industry was focused on producing template-based solutions.
Justt is serving the world’s largest enterprises and is setting the bar for enterprise security requirements in the chargeback space. New and exciting product developments led Justt to seek PCI DSS compliance.
— A roadmap of new client segments with PCI compliance as an evaluation criteria
— An internal bar for compliance that was already high, this wasn't crisis response, it was proactive investment
— A new product road map that triggered PCI scope before a single customer transaction was processed
Justt wanted to raise its security posture to further increase its security & data privacy posture and open the door to new product lines.
WHY JUSTT CHOSE GRSEE
When evaluating PCI DSS QSA partners, Justt ranked its priorities clearly:
— Expertise: deep, hands-on knowledge of PCI DSS, not a checklist approach
— Speed: the ability to move at the pace of the business, not the audit calendar
— Personal attention: direct access to the people doing the work
— Price: important, but never the deciding factor
GRSee had already earned that trust. Justt considered other firms, but chose GRSee based on experience from previous projects and strong internal recommendations, a repeat relationship built on delivery, not a first-time pitch.
THE ENGAGEMENT
“The process was smooth and well-structured from day one” Justt shared. “Kickoff was thorough, the team took time to understand our environment and goals before anything started, so expectations were clear on both sides.”
That clarity carried through the entire engagement. Communication stayed consistent, regular updates, quick responses, and no surprises along the way.
What stood out most in GRSee's service model? Clear guidance and responsiveness, the two things that turn a compliance audit from a black box into a partnership.
KEY RESULTS
— Certification in record time: Justt achieved its PCI DSS Level 1 ROC in 3 months, record time for one of the most demanding certifications in payments.
— Stronger compliance program: The engagement improved Justt's overall security and compliance posture, not just the single certification target.
— Sales-cycle leverage: A stronger compliance program now supports greater trust with enterprise buyers, as well as PSPs and financial institutions, and fewer stalls during security review.
— Launch-ready roadmap: The certification cleared the path for Justt's AI-based product roadmap to develop new products.
