Cyber Security Perth
Layered cyber security for Perth businesses. Audits, 24/7 monitoring, incident response and DMARC — all from a team that's been securing small business since 1998.
Stop hoping. Start knowing.
Most small business "security" is a firewall, an antivirus, and a lot of crossed fingers. We replace crossed fingers with monitoring, controls and a plan — so the next phishing email, misconfigured share or stolen laptop is a non-event instead of a headline.
What we do
- Cyber security audit — a full sweep of your identity, endpoint, email and cloud posture with a prioritised remediation list.
- 24/7 monitoring — endpoints, identities and email watched continuously, with alerts triaged before you see them.
- Incident response — when something goes wrong, we're on it within the hour, not next business day.
- DMARC, SPF and DKIM — stop anyone impersonating your domain. Deployed and monitored through our own SaaS, DMARC Busta.
- Security awareness — training your staff to spot the real threats instead of clicking through warning dialogs.
- Compliance support — Essential Eight, Privacy Act, industry-specific frameworks.
Why HCS
- Perth-based, since 1998. Same phone number, same founder, 28 years of fixing the thing before it breaks.
- We build security tools. DMARC Busta is our SaaS — you're working with the people who wrote the platform other MSPs use.
- No lock-in on marketing. Plain-English reporting. You'll know exactly what's working and what isn't.
Cyber security services for Perth businesses
We deliver cyber security services across Perth — Belmont, the CBD, the eastern suburbs, the industrial corridors out to Kewdale and Welshpool, and right across the metro area. Most engagements are remote-first (because most modern attacks are), with onsite work when an audit, hardware refresh or incident response calls for it.
Whether you need a one-off cyber security audit in Perth, ongoing managed protection, or someone to talk through Essential Eight compliance for your industry, we can scope something that fits the size of your business and the size of your risk — without selling you enterprise tooling you don't need.

* A Security Operations Center (SOC) is a centralised team that monitors, detects, analyses and responds to security events across your systems 24/7. SOC coverage is included from the Watched plan up — it is not held back for the top tier.
Managed security plans
Three plans. Same service, different depth of protection.
Every plan gets the same support and the same guaranteed response times — what changes is how much of the stack is watching your business. Priced per device once we know what you are running.
