Small & Medium Businesses
Protect your team, customers and revenue
A small or medium business is big enough to be a worthwhile target for attackers — holding customer data, processing payments, running payroll — but usually without a dedicated security team to defend it. That combination makes SMBs one of the most commonly breached categories of organization, and recovery costs (lost customers, legal exposure, downtime) can be existential for a smaller company. This section focuses on the essentials that protect your team, your customers, and your revenue without requiring enterprise budgets or headcount: access control, patching, backups, phishing awareness, and having a basic incident response plan before you need one.
