When purchasing security tools (e.g., Firewalls, Antivirus, Endpoint Detection), consider the following:
• Identify Assets: Know your critical systems, such as email (Microsoft 365), banking, and CRM.
• Prioritize 80/20 Rule: Focus on the 20% of efforts that yield 80% of security benefits.
• External Attack Surface Management (EASM): Consider tools that monitor for vulnerabilities from the outside in, especially if you have web-facing services.
• Scalability: Ensure software can grow with your business and integrates with existing infrastructure. National Cyber Security Centre - NCSC.GOV.UK +4 4. Managed Security Services (MSSP) If in-house expertise is lacking, partnering with an IT support provider is a valid approach:
• Define Metrics: Ensure your provider gives clear, relevant metrics (not just jargon) to demonstrate value.
• Phased Migration: Implement new security tools in stages rather than all at once.
• Verify Expertise: Ask for case studies, industry-specific experience, and evidence of how they protect your data. Chess ICT +2 5. Compliance and Training
• Cyber Essentials: Consider certification to prove to clients that you take data protection seriously.
• Employee Training: Regularly train staff to identify phishing links and avoid weak password habits.
• Data Audit: Identify all personal data handled and ensure compliance with privacy regulations. NCSC UK +3 6. Budgeting Tips
