Expect a practical, prioritized approach to risk management rather than overwhelming checklists. The firm's methodology focuses on defining measurable progress and delivering on-time, on-budget results. Their partner-level engagement model means clients work directly with experienced practitioners rather than being handed off to junior staff.

tw-Security operates exclusively in healthcare, serving covered entities including academic medical centers, community hospitals, specialty hospitals, critical access hospitals, physician practices, payers, and clearinghouses. The firm also supports business associates including health management networks, application vendors, life sciences companies, revenue cycle providers, and mobile health vendors.

Their healthcare specialization extends to understanding regulatory nuances across HIPAA, state privacy laws, and healthcare-specific frameworks like CSA Section 405(d) HICP. The firm addresses healthcare-unique challenges including biomedical device security, protecting electronic protected health information (ePHI), and managing business associate relationships within the healthcare ecosystem.

The ideal client is a healthcare delivery organization, payer, or business associate with 100+ employees that needs specialized HIPAA compliance support, is preparing for or responding to regulatory scrutiny, or requires strategic security program development. Organizations seeking vendor-neutral assessments, virtual CISO services, or biomedical device security expertise will find strong alignment with tw-Security's capabilities.
