Four Blocks Advisory is a consulting firm dedicated to helping organizations navigate the complex landscape of security and compliance.
We specialize in designing security architectures based on compliance frameworks such as PCI DSS, ISO 27001, NIST, CIS, GDPR, and others. Our work is rooted in technical depth as applicable to the card industry, but we consult more broadly across multiple industries, such as Banking and finance, retail, and IT sectors.
We’re fluent in control frameworks and regulatory requirements.
But Four Blocks isn’t just about controls — it’s about clarity. We translate regulatory complexity into actionable security posture. Our approach blends strategic insight with evidentiary thinking, ensuring that every decision in your architecture is defensible and future-ready.
Whether you’re designing a credentialing API, segmenting a secure DMZ, or aligning process controls with compliance workflows, we bring methodical rigor and modern thinking to every layer of trust.
