Key facts

• The average self-reported cost of cybercrime for an Australian small business reached AU$56,600 per report in 2024-25, up 14 per cent in a single year (ASD).
• ASD’s ACSC received more than 84,700 cybercrime reports in 2024-25, roughly one every six minutes.
• Across all businesses, the average self-reported cost of a cybercrime report rose 50 per cent to AU$80,850.
• Business email compromise remains Australia’s costliest cybercrime category for organisations.
• The Essential Eight is the ACSC’s baseline set of eight mitigation strategies, and it underpins how 4iT hardens an SME environment.

What does managed IT security cover for a Sydney business?

Managed IT security covers every layer an attacker might target: identity, endpoints, email, network, data, and the people using all of it. No single product covers all of those, which is why we run them as one program rather than selling a box and walking away. The layers we manage for Sydney SMEs break down like this.Endpoint security. Every laptop, desktop, and server runs managed protection that detects and isolates threats before they spread. More on our endpoint security approach.Email and spam protection. Email is still the front door for most attacks, so filtering, anti-phishing, and impersonation protection sit in front of every mailbox. See email and spam protection.Managed cybersecurity. The day-to-day protection stack, hardening, and policy enforcement that keeps an environment defensible. See cybersecurity services.Managed detection and response. Round-the-clock threat monitoring and response, so an alert at 2am on a Sunday is dealt with, not waiting in a queue until Monday. See managed detection and response.Security awareness training. Your staff are the most-targeted layer, and trained staff are measurably harder to fool. See security awareness training.Penetration testing. Independent testing that finds the gaps before an attacker does. See penetration testing.Cyber security audits and risk assessments. A clear-eyed look at where you actually stand, mapped to a real framework. See cyber security audits.Essential Eight uplift. Bringing an environment up to the ACSC’s baseline maturity, step by step.

How does 4iT secure a Sydney SME?

4iT secures an SME with defence in depth: layered controls so that if one fails, another still stands between the attacker and your data. There is no single switch that makes a business secure, and anyone who tells you otherwise is selling something. What works is a stack of sensible controls, each doing its job, all monitored centrally.In practice that starts with identity. We turn on multi-factor authentication everywhere it can go, lock down Microsoft 365 with conditional access, and remove the standing admin rights that attackers love. Then endpoints get managed detection and response, email gets filtered and impersonation-protected, and backups get made immutable so ransomware cannot quietly encrypt them too.We work to the Essential Eight as the baseline because it is the framework the Australian government actually publishes and updates, not a vendor’s marketing model. The ACSC’s current advice to every business is blunt: assume compromise, log everything, replace legacy technology, and choose products that are secure by design. That is the lens we apply when we assess and harden a Sydney SME environment.One thing we see constantly: the businesses that get hurt are rarely the ones with no security at all. They are the ones with security that was set up once, years ago, and never reviewed. A managed program exists precisely so that does not happen to you.

What is the Essential Eight, and does your Sydney business need it?

The Essential Eight is a set of eight baseline mitigation strategies published by the Australian Cyber Security Centre to reduce the risk of the most common cyber attacks. They cover application control, patching applications, patching operating systems, configuring Microsoft Office macros, hardening user applications, restricting administrative privileges, multi-factor authentication, and regular backups. Each is rated across maturity levels from zero to three.Most Sydney SMEs are not legally required to implement the Essential Eight, but that misses the point. It is the clearest, cheapest, government-backed checklist of what actually stops attacks, and reaching even Maturity Level One closes the doors attackers walk through most often. If you tender for government work, sit in a regulated industry, or want your cyber insurance renewal to go smoothly, you will likely be asked about it directly.We explain the framework in plain English in our guide to the ASD Essential Eight for Australian SMEs, and we deliver staged uplift through our Essential Eight uplift service.

How much does managed IT security cost for a Sydney SME?

Managed IT security for a Sydney SME is usually priced per user per month, either bundled into a managed IT support agreement or run as a standalone security layer over your existing IT. The figure depends on your headcount, how mature your current setup is, and how much round-the-clock monitoring you need, so a 10-person accounting firm and a 60-person logistics business will pay very different amounts.For project work such as a security audit, an Essential Eight assessment, or a penetration test, we quote a fixed scope. Advisory and consulting work is charged at AU$165 per hour ex GST. We would rather give you a real number against your actual environment than a misleading headline price, so the honest answer to “how much” is: book a short call and we will scope it.Whatever the figure, weigh it against the AU$56,600 average cost of a single cybercrime incident for an Australian small business. The maths on prevention is not close.
