Billing and customer platforms hold your revenue and your customers' data. I design security into these systems from the start and help you prove it to auditors, regulators and partners.
Support can be a short, focused engagement or ongoing architecture and delivery help.
Security architecture for BSS, CRM, charging and integration platforms, built into the design rather than added later.
Role-based access, privileged access and segregation of duties for revenue-critical systems.
Firewall modernization, segmentation and threat detection for data centre and cloud environments.
Controls, evidence and documentation for audits, including ITSM and SOX-style controls.
Continuity and disaster recovery plans, drills and recovery readiness for critical services.
Security requirements and reviews for vendors, integrators and outsourced operations.
18+ years building and running revenue-critical platforms.
A simple, transparent way of working, adapted to the size of your project.
BSS holds customer identities, payment data and the rules that decide what customers are charged. A weakness there can mean data breaches, revenue leakage or fraud, so access, integrations and data flows need specific controls.
Yes. I help map your controls to the audit requirements, close gaps and organize the evidence so the audit runs smoothly.
