- ☐ Compare in-house security management vs. outsourcing cybersecurity services
- ☐ Prioritize investments in high-risk areas based on security assessments
- ☐ Plan for regular cybersecurity upgrades as threats evolve
- ☐ Consider open-source or cost-effective security solutions for SMBs
12. Cyber Insurance
- ☐ Assess whether cyber liability insurance is needed for your business
