Provider information reviewed
Mosman businesses comparing cyber security companies generally have three choices: an integrated managed IT and security provider, a specialist cyber consultancy, or a large national provider. The right model depends on whether you need day-to-day ownership, independent testing, compliance support, continuous monitoring or enterprise-scale incident response.
This guide compares six cyber security companies that publicly state they serve Sydney or Australian organisations. It explains how their service models differ, what their official websites say they provide and which questions Mosman buyers should ask before signing an agreement.
Which Type of Cyber Security Company Is Likely to Suit?
The practical answer:
- Integrated managed IT and cyber ownership: Stanfield IT.
- A cyber-only specialist with broad advisory, testing and managed capability: Gridware.
- Penetration testing, application security or defined technical assurance: Project Black or Vertex Cyber Security.
- Integrated ICT and cyber services for a mid-market environment: Tecala.
- Enterprise or government scale and a very broad national capability: CyberCX.
That does not make one provider universally better. A 35-person professional firm wanting Microsoft 365 protection and responsive IT support has a different buying problem from a listed company seeking digital forensics, complex governance and a large managed SOC.
How We Selected the Companies
To keep the comparison useful and defensible, the article includes companies with an active official website, a clear Sydney or Australian service proposition, enough public information to verify their core offering, and a delivery model that gives Mosman buyers a meaningful point of comparison.
This is not a mystery-shopping review. We did not test help desks, inspect contracts, audit tools or independently validate every marketing claim. Public claims may change, which is why the review date is shown and every provider profile links to an official source.

Understand the Three Provider Models First
Most shortlists mix companies that solve different problems. Separating the provider models first makes the comparison fairer.
Integrated managed IT and cyber
One provider manages everyday IT operations and agreed security controls. This can improve ownership because identity, Microsoft 365, endpoint management, patching, backup, support and security reporting sit within one operating model.
Watch for: whether the provider has genuine cyber depth, who validates alerts, and what specialist work is delivered internally or through partners.
Specialist cyber consultancy
A cyber-only firm usually focuses on testing, assurance, advisory, monitoring, incident response or compliance. It may work alongside an internal IT team or an existing MSP.
Watch for: who implements and maintains the recommendations after the specialist engagement ends.
Large national or enterprise provider
A large provider can offer broad disciplines, mature platforms and substantial incident capability. This is valuable where scale, complex regulation, operational technology or national coverage matters.
Watch for: minimum contract size, service layers, account access and whether the model remains responsive for a smaller organisation.
Common variation: co-managed security
Co-managed delivery combines the client’s internal IT capability with defined external security functions. The external provider might own MDR, vulnerability management, testing, governance or incident escalation while internal staff retain operational control.
Watch for: gaps between teams. Every control, alert and remediation action needs a named owner.
Six Cyber Security Companies to Consider
CyberCX
CyberCX publishes the broadest service catalogue in this comparison. Its official site lists strategy and consulting, governance, risk and compliance, security testing, identity and access management, cloud security, managed security, education, digital forensics and incident response.
Its managed-security material describes 24/7 monitoring across on-premises, cloud, edge and hybrid environments, including SOC, SIEM, endpoint detection and response, vulnerability management and access to digital-forensics capability. That breadth is most relevant where scale, regulation and complex incident handling matter.
Likely fit: Larger or highly regulated organisations that need broad disciplines, substantial incident-response capability and enterprise-scale operations. A smaller Mosman business should confirm commercial minimums, account structure and the level of direct access it will receive.
Gridware
Gridware describes itself as a Sydney-founded specialist focused on cyber security rather than general IT. Its public offering includes penetration testing, managed security, digital forensics, incident response, virtual CISO and cyber advisory services.
That specialist focus may appeal to organisations that already have an internal IT team or MSP but need deeper independent cyber capability. It can also suit buyers who want an external firm to challenge the assumptions made by their day-to-day technology provider.
Likely fit: Organisations looking for a cyber-only specialist across advisory, testing, managed security or incident work.
Project Black
Project Black describes itself as an Australian CREST-accredited cyber security consultancy with consultants and offices in major Australian cities, including Sydney. Its official service menu includes penetration testing, application security, ISO 27001 support, security engineering and managed security.
Its testing scope publicly covers web applications, internal and external networks, mobile applications, social engineering and wireless networks. This makes it one of the more clearly defined technical-assurance options in the shortlist.
Likely fit: Businesses needing an authorised penetration test, application-security review or a specialist technical project with a clearly bounded scope.
Stanfield IT
Stanfield IT operates from Frenchs Forest and combines managed IT with cyber security for Australian businesses. Its service model covers risk assessment, identity and cloud hardening, managed detection, vulnerability management, testing, security awareness, incident readiness and executive reporting.
The practical difference is operational ownership. The same team can help identify a risk, implement the control in Microsoft 365 or the managed environment, support users, monitor the outcome and report progress. Stanfield IT can also work in a co-managed model with an internal IT team or another provider.
Likely fit: Growing Mosman businesses that want a local, Australia-based team to connect day-to-day IT operations with security improvement and reporting. Review Stanfield IT’s complete security offering.
Tecala
Tecala publishes an integrated Sydney ICT and cyber security offering. Its listed capabilities include cyber assessments, SIEM and MDR, vulnerability scanning, penetration testing, incident response and forensics, training, endpoint protection, backup, cloud security and network security.
Like Stanfield IT, Tecala can connect broader technology operations with ongoing security services, although its public positioning and service breadth suggest a mid-market managed-services model.
Likely fit: Mid-market organisations wanting cyber security integrated with a broader managed ICT relationship.
Vertex Cyber Security
Vertex Cyber Security states that it is 100% Australian owned and was founded in 2016. Its official site lists penetration testing, cyber audits, ISO 27001, Essential Eight and SOC 2 support, secure-code and awareness training, incident response, managed services and SOC monitoring.
Vertex also publishes CREST, ISO 27001 and ISO 27701 credentials. As with any provider, buyers should confirm the current legal entity, certification scope, expiry or renewal status and whether the credential directly relates to the proposed work.
Likely fit: Organisations prioritising penetration testing, assurance, standards-led improvement, training or a specialist engagement alongside existing IT.
What Mosman Businesses Should Compare
A polished proposal can conceal major differences in scope. Compare providers against the same written requirements rather than letting each company define a different service and then comparing only the monthly total.
- Business outcomes: what risk, operational problem or obligation must the engagement address?
- Included environment: users, devices, servers, cloud platforms, identities, locations, applications and third parties.
- Monitoring scope: which data sources are monitored, during which hours, by whom, and with what escalation timeframes?
- Authority to act: can the provider isolate a device, disable an account or block activity, or does it only send an alert?
- Remediation ownership: who fixes vulnerabilities and configuration gaps after they are identified?
- Incident response: availability, rates, retainers, notification commitments, forensic capability and insurer coordination.
- Reporting: what will directors, management and technical staff receive, and how often?
- Provider security: how the provider protects privileged access, staff accounts, remote administration tools and client information.
- Contract and exit: exclusions, project rates, subcontractors, data location, termination, credential return and handover.
ASD advises organisations to scrutinise the security of contracted ICT services, put security expectations and incident notification into contracts, control provider access, preserve useful logging and maintain a practical response plan. Its separate question guide recommends asking whether the provider applies better-practice controls, securely administers systems, monitors activity, assesses vulnerabilities and is prepared to respond to incidents. See the official ASD guidance for engaging an MSP and questions to ask providers.
Credentials: Check What They Actually Prove
Credentials matter when they relate directly to the work being purchased, but they should not replace due diligence.
Penetration testing
For an authorised penetration test, ask who will perform it, what qualifications and experience they hold, whether the provider has relevant CREST accreditation, what methodology will be followed, and whether retesting is included.
ISO 27001
A provider’s own ISO/IEC 27001 certification concerns the scope of its information security management system. It does not automatically certify your organisation and does not make the provider your independent certification body.
Essential Eight
The Essential Eight is an ASD-recommended baseline of mitigation strategies, not a commercial product badge. Ask how the provider assesses maturity, validates evidence, manages exceptions and maintains controls after uplift.
Vendor partnerships
Vendor status may demonstrate training or product experience. It does not prove that the proposed design, monitoring model or response process is suitable for your business.
ASD recommends the Essential Eight as a baseline that makes systems harder to compromise, while recognising that no set of controls guarantees protection against every threat.
Questions to Put in the Request for Proposal
- Which parts of our environment are included, and which are excluded?
- Who owns each control and remediation action: us, you or another supplier?
- What is monitored, during what hours, and by which team?
- What constitutes a security incident, and how quickly must you notify us?
- Can you take containment action, and what approval is required?
- How do you protect privileged access to customer systems?
- Which services are delivered by employees and which use subcontractors or partners?
- Where are logs, backups and client information stored and processed?
- What reporting will management receive, and what decisions will it support?
- What happens when a vulnerability or control gap falls outside the monthly scope?
- What evidence, references or case studies can you provide for similar organisations?
- What assistance, data and credentials will be provided when the agreement ends?
How to Compare Cyber Security Pricing
Do not compare a per-user fee, project total or monitoring price in isolation. One proposal may include licences, endpoint response, cloud monitoring, remediation, reporting and incident preparation. Another may cover only the alerting platform.
Ask every shortlisted provider to price the same baseline scope and separate:
- One-off assessment and onboarding
- Recurring licences and managed services
- Monitoring hours and response coverage
- Implementation and remediation projects
- Incident-response rates or retainer
- Optional services and exclusions

Does the Provider Need to Be in Mosman?
No. Much of modern security assessment, cloud configuration, monitoring and response can be delivered remotely. The more useful questions are whether the team is accessible, whether support aligns with Australian business hours and law, whether onsite attendance is genuinely available when needed, and whether named people remain accountable.
A nearby Sydney provider can be valuable where cyber work overlaps with Microsoft 365, devices, networks, backups, user support or an onsite incident. A national specialist may be stronger where the requirement is a tightly defined penetration test, complex digital forensics or a large compliance program. Choose proximity where it improves delivery—not merely because “local” appears in a page title.
Where Stanfield IT Fits
Stanfield IT is based in Frenchs Forest and is best considered where a Mosman business wants cyber security connected to the systems and support model it uses every day. The service can begin with a cyber security risk assessment, continue through identity, Microsoft 365, endpoint and cloud hardening, and add Managed Detection and Response, vulnerability management, penetration testing, Essential Eight uplift and incident readiness as required.
The model can be fully managed or co-managed. The proposal should state what Stanfield IT owns, what remains with the client or another provider, which hours are covered, how alerts are escalated and which work is separately scoped.
For organisations seeking a global enterprise provider or a stand-alone specialist test, another company in this comparison may be a better fit. For a growing business wanting one local team to connect IT operations, security controls and executive reporting, book a discussion with Stanfield IT.
Frequently Asked Questions
Are these companies physically based in Mosman?
Not necessarily. They publicly serve Sydney or Australian organisations. Check each provider’s current office location, onsite terms and service area rather than assuming it has a Mosman office.
Should a Mosman business choose a local or national provider?
Choose according to risk and service model. Local access can improve accountability and onsite support; a national specialist may suit complex testing, incident response or enterprise requirements.
What is the difference between an MSP and a cyber consultancy?
An MSP usually owns recurring IT operations and agreed security controls. A cyber consultancy normally provides specialist assessment, testing, advisory, monitoring or incident work alongside an IT team or MSP.
What should a managed cyber proposal include?
It should define systems, users, data sources, monitoring hours, escalation, response authority, remediation ownership, reporting, exclusions, project rates, subcontractors and exit arrangements.
Does every business need 24/7 monitoring?
Not automatically. The decision depends on operating hours, risk, system criticality, insurance and response capability. Confirm who validates after-hours alerts and what action they can take.
What credentials should be checked?
Check credentials relevant to the work: testing accreditation and tester experience, the scope of ISO certifications, staff capability, insurer acceptance, references and evidence of secure service delivery.
Can a cyber company work with our existing IT team?
Yes. A co-managed model can assign MDR, testing, vulnerability management, governance or incident escalation externally while the internal team retains agreed operational responsibilities.
How much do cyber security companies charge?
Pricing varies by scope, users, devices, platforms, monitoring hours, risk and response obligations. Compare the same written scope and separate recurring services from projects and incident work.
Final Recommendation
Shortlist two or three providers with the right delivery model, give them the same written scope and insist on clear answers about ownership, privileged access, monitoring, remediation and incident response. The best proposal is not necessarily the longest or cheapest; it is the one that makes responsibility and outcomes unmistakable.
