OpusComputer security basics every small business should have
Most breaches at small companies aren't sophisticated — they exploit missing fundamentals. A handful of controls stops the overwhelming majority of them.
The high-leverage basics
- Multi-factor authentication everywhere. A stolen password is useless without the second factor. Turn on 2FA for email, finance, and admin tools first. (Opus itself supports authenticator-app, email, and SMS 2FA.)
- Patch quickly. Auto-update operating systems and browsers. Most exploited flaws have fixes that sat uninstalled.
- Least privilege. Not everyone needs admin rights. Scope access to the role.
- Backups you've tested. A backup you've never restored is a guess. Verify it.
- Know your fleet. You can't secure devices you can't see. Knowing which company computers are active, and when, is itself a security control.
Visibility is security
On company-owned machines, knowing what's installed and how devices are used helps you spot the odd one out — a computer suddenly running unfamiliar software, or reporting from an unexpected place. Transparent activity insight and an up-to-date device inventory are quiet but powerful parts of a small-business security posture.
