About us

About Reliable Computers | Managed it support Sydney | Computer repairs Sydney & St George

Penshurst traders run their whole business through email, banking and cloud apps. We secure those accounts — Microsoft 365 hardening, multi-factor authentication, ESET endpoint protection — and keep backups you can actually restore from. Staff phishing awareness is part of every Penshurst engagement, because the most common breach still starts with one clicked link. We protect Penshurst businesses along Forest Road from phishing, fraud and ransomware — proportionate, locally-managed security from a team minutes away in Oatley.

    Is my business email secure because I use Gmail or Outlook? Using Gmail or Outlook provides a strong platform, but true business email security requires correct configuration of authentication records like SPF, DKIM, and DMARC. Many assume built-in security is enough, but without proper setup, your business remains vulnerable to phishing and spoofing attacks. Our team specialises in business email security audits to ensure your setup is robust. Call us on 1800 753 991 for a free consultation.
