Brier & Thorn

Brier & Thorn is a managed security service provider (MSSP) offering a vendor-neutral security operations center covering managed detection and response (MDR), penetration testing, incident response and forensics, risk assessments, and information security management system (ISMS) program development. Its “SecOps-as-a-Service” offering packages outsourced security operations functions — tooling, monitoring, and analyst expertise — for organizations that don’t want to build and staff a SOC internally, backed by threat intelligence feeds the company says keep detection logic current against emerging threats.

Founded around 2010 and headquartered in San Diego, California, with an operating entity in Mexico supporting Latin American clients, Brier & Thorn is ISO 27001 certified — an independently auditable standard for information security management that provides real third-party verification of its internal security processes, distinct from unverifiable marketing claims. The company has also formed technology partnerships, including a 2022 agreement with BlastWave to resell BlastShield OT/ICS network security in North and Latin America and a services partnership with Tego Cyber for threat intelligence.

Brier & Thorn’s vendor-neutral SOC model is a well-established MSSP pattern rather than a novel technology, and its cross-border North America/Latin America footprint is its main practical differentiator versus similarly sized US-only MSSPs. No independent, named case study quantifying detection or response-time outcomes was found; assessment of its actual SOC performance depends largely on the company’s own materials and its ISO 27001 certification as a process-maturity signal.
