Beyond Antivirus: What SMBs Overlook in Cybersecurity

Antivirus software is essential, but it’s only one piece of a much larger puzzle.

Too many SMBs rely solely on endpoint protection, leaving their email systems, cloud infrastructure, and domain configurations wide open.

Modern Threats Bypass Traditional Defences

Cyberattacks don’t always involve infected files. They exploit weak domain settings, unprotected web access, and misconfigured DNS. These are areas that antivirus cannot touch.

Microsoft’s Security for SMBs Resource Center outlines why multi-layered protection is now the standard.

What Are You Missing Outside the Endpoint?

A Cyber Essentials Health Check looks beyond the laptop to assess what attackers see when they scan your domain. Key gaps that get checked include:

  • Email Authentication Failures: SPF, DKIM, and DMARC prevent impersonation attacks.
  • SSL/TLS Certificate Issues: Expired or weak encryption protocols.
  • Open Remote Access Ports: RDP, SSH, FTP exposed to the public.
  • Missing Security Headers: Lack of X-Frame-Options, CSP, HSTS and more.
  • Publicly Accessible Admin Panels: Login pages indexed by search engines or scanners.

Good Antivirus is Just a Start, Not a Strategy

Cybersecurity is beyond what is installed on devices. It also includes how your business presents itself online, too.
