Sentry Cyber

Sentry Cyber is a cybersecurity consultancy founded in 2024 and headquartered in Docklands, Brisbane City, Australia. The agency positions itself as Australia's only dedicated cybersecurity consultancy focused exclusively on Google Workspace environments. It serves organisations across Australia and New Zealand, with a team of under 49 employees.

The agency offers a comprehensive range of services starting with cybersecurity risk assessments aligned with NIST CSF 2.0, Essential Eight, and SMB1001 standards. From these assessments, Sentry Cyber builds tailored 12- to 24-month roadmaps to improve security maturity and reduce risk exposure. Additional services include ongoing security posture reviews, data loss prevention (DLP) configuration, backup and recovery solutions, and identity and access management enhancements such as MFA, SSO, and role-based access.

Sentry Cyber works with clients across multiple industries, including crypto, corporate services, delivery and takeaway, eCommerce, education, automotive, fintech, finance, hospitality, and software and IT services. The agency serves startups, small businesses, medium businesses, and enterprise or corporate clients. It also partners with MSPs and in-house IT teams, acting as a dedicated cybersecurity arm for providers that lack specialised Google Workspace security expertise.

The agency has a 5.0 Google rating from 187 reviews. Clients consistently praise the team's knowledge, responsiveness, and clear communication. One client noted that Kelvin provided "excellent support" and was "organised, patient, and proactive." Another client highlighted that Sentry Cyber "delivered complex solutions in a clear, commonsense way that made implementation straightforward and effective." A third client appreciated the team working over holidays and outside business hours to complete a complex migration.

Sentry Cyber's leadership includes CEO Adrian, who founded Onsite Helper in 2006, and CEO Anurag Adhikari, who has over a decade of experience in penetration testing, malware analysis, digital forensics, and incident response. The agency counts Tenable, Spin.ai, and Zscaler among its clients. With a minimum budget under $1,000 and an average hourly rate of $25, Sentry Cyber provides accessible specialised cybersecurity consulting for Google Workspace users.
