Brian Cusack

I've helped close complex, multi-million-dollar enterprise security deals across healthcare, insurance, retail, and banking. At Critical Start, I drive technical evaluations for MDR, Managed SIEM, and Managed VM solutions and helped close two $500K ARR deals with SHI and Guidepoint Security.

At Tripwire, I spent nearly 17 years guiding technical sales, proofs of concept, partner enablement, and customer presentations. I helped turn a lapsed insurance and financial-services customer into a $4.3M+ deal and supported a $2.6M win with a large cosmetics manufacturer through a multi-week POC.

I've also designed biometric capture solutions at IDEMIA and supported data protection evaluations at HelpSystems, including data classification, data loss prevention, and digital rights management. I use the CIS Critical Security Controls to help customers prioritize security spending and communicate effectively with engineers, executives, and end users.

Earlier in my career, I built applications and automated testing solutions, taught technical courses, and managed consulting teams. I'm fluent in English and Spanish and have supported sales teams, partners, presentations, and proofs of concept throughout the US, Canada, and LATAM.
