Exposure Impact

Title: Post-Breach Essentials for Small Businesses

Description: After a breach, small businesses face urgent decisions but typically lack the resources to respond and recover quickly. Organizations must act decisively to limit damage, preserve forensic evidence, and coordinate a clear response plan across leadership and vendors. Key actions include isolating systems, resetting credentials, avoiding common errors (e.g., deleting logs or alerting attackers), legal engagement, and early notification to cyber insurers and regulators. Emphasis is placed on building resilience through tabletop exercises and response planning to prevent future incidents.
