The cybersecurity buying reality
Most firms stop at prevention. GDF connects prevention, response, evidence, and testimony.
Cybersecurity buyers do not only need a scanner report. They need a firm that can harden systems before an attack, respond when something goes wrong, collect and preserve evidence, explain technical findings to nontechnical stakeholders, and support counsel when the matter becomes adversarial.
Application security, source review, and vulnerability management are revenue protection.
AI security needs governance, data controls, red teaming, and forensic readiness.
