      Riel's Review Sourced from Google

      I've had my ups and downs hiring various IT professionals to assist in our tech operations. A trusted friend recommended this firm, and since then, I haven't looked back. Dealing with ITAdOn has been delightful; they have been our most reliable partner so far, and no provider I've ever hired has come close in terms of responsiveness, accountability, and professionalism.I've achieved great results with them, receiving fantastic IT support and meeting our recruiting needs. Huge thanks to the ITAdOn team for helping us scale our business.

      I have been very satisfied with the IT Support we have received from ITAdOn. ITAdOn has helped us build a secure IT infrastructure that gives us peace of mind (especially where there are a lot of cybersecurity and ransomware risks nowadays). Every staff member is very competent, responsive, and easy to work with. They treat us like their own and do whatever it takes to properly get the job done. The team members at ITAdOn are truly the professionals you want on your team helping you out when your technology snags an issue. Knowing I can rely on them, they are our go-to IT support company here in Philadelphia! I highly recommend them.

      ITAdOn has been managing our IT infrastructure for the last few months and we couldn’t be happier. The technical support team is very responsive and extremely knowledgeable. I feel great that our network, server, and our workstations are up to date and running smoothly. They recently upgraded our workstations to Windows 11 which was effortless on our end and everything is working seamlessly. Very happy with their service.

      Ethan and his team at Milnsbridge have been super helpful and friendly in supporting us at the company I work for (Polaris Marine) recently when our phone system needed updating. It was a large operation that needed ongoing monitoring, and Ethan was reliable and proactive in getting things done on time and offering us the support we needed to keep things running smoothly.

Frequently Asked Questions

What certifications should a cybersecurity company in Australia have?

  • Australian Cyber Security Centre (ACSC) 
  • Australian Signals Directorate (ASD) 
  • CompTIA  
  • SANS Institute  
  • ISACA  
  • Global Information Assurance Certification (GIAC) 

Additionally, Australian cybersecurity companies must be familiar with the Australian Privacy Principles, Essential Eight framework, NIST-CSF framework, and Defence Industry Security Program. They should also have an Infosec Registered Assessors Program (IRAP) assessment. 

What should I look for when hiring an Australian cybersecurity firm?

When hiring an Australian cybersecurity firm, look for the following qualifications to verify expertise and reliability: 

  • Proven track record in your industry and system 
  • Knowledge of the latest global and local trends, threats, and best practices 
  • Relevant certifications and accreditations
  • Verifiable client reviews and references
  • Transparent reporting and auditing processes
  • Business stability
  • Cultural fit

What red flags should I avoid when selecting a cybersecurity company in Australia?

When selecting a cybersecurity company in Australia, avoid the following red flags: 

  • Limited knowledge of Australian-specific cybersecurity regulations and frameworks 
  • Outdated company certifications, accreditations, and assessments 
  • Inadequate case studies and project portfolios, particularly in your industry and requirements 
  • Pattern of problematic behaviour, as highlighted in client reviews 
  • Unwilling to provide the credentials of its individual team members

What factors affect the pricing of an Australian cybersecurity firm?

A business’s IT infrastructure size, complexity, and security strength are the primary factors that affect the pricing of an Australian cybersecurity firm. Other factors include type and level of security, industry-specific compliance requirements, and the number of users and devices. 

For instance, network monitoring can cost between $100 and $2,000 per month. On the other hand, a security operations centre (SOC) for cloud cybersecurity costs $2,7000 per professional on average.  

How do cybersecurity companies in Australia measure project success?

  • Risk and control maturity: Essential Eight, security audit compliance, and level of preparedness
