Well, for a small company you’ll still see the usual suspects. Phishing is always the first line—employees tricked into giving up credentials or opening malware. Insider threat can be subtle, like a disgruntled staff member or a careless user who leaves a laptop unattended. Weak or reused passwords give attackers a quick hop. Unsecured endpoints—phones, laptops, IoT devices—can slip in. Misconfigured network gear or open ports can let an attacker map the internets. And don’t forget supply‑chain risk; a third‑party vendor with lax security can be an entry point. Keep those in mind when you lay out your detection layers.
