## Brand & Positioning

### Voice & Tone

- Speak to CISOs, security engineering leaders, application/cloud/network security teams, GRC and compliance officers, and boards.
- Use a technical, evidence-based tone anchored in named methodologies, frameworks, and specific test coverage rather than generic marketing claims.
- Emphasize the "Human-Led, AI-Accelerated" positioning: testers are in-house employees augmented by purpose-built AI, not automated scanning alone or outsourced/crowdsourced labor.
- Reference more than 20 years of proactive security history dating to NetSPI's 2001 founding.

### Target Audience

- CISOs and security leaders at mid-market to large enterprises, especially regulated industries (financial services, healthcare, insurance).
- Application, cloud, and network security engineering teams needing recurring or continuous pentesting rather than a single annual test.
- GRC, compliance, and audit teams responsible for PCI DSS, GLBA, DORA, SOX, NIST 800-53, and HIPAA testing requirements.
- M&A due diligence teams assessing cybersecurity risk of acquisition targets.
- Teams building or deploying AI/LLM applications who need adversarial testing of models and AI pipelines.
- Detection engineering and SOC teams validating EDR/SIEM/SOAR/MSSP coverage against real attack simulations.
- Automotive, medical device, industrial/OT, and other hardware/embedded systems manufacturers.
