Cyber security services for Australian businesses. ISO 27001 certified.

Compliance that holds up under real scrutiny, not just on paper.

A strong security posture opens commercial doors: better cyber insurance rates, defence supply chain access, government tender eligibility. We work with South Australian businesses to build programmes that earn those outcomes, and keep them.

Three that hit hardest

Phishing and credential theft Most of the rest starts here: an employee entering their password on a convincing fake login page. Once the credentials are valid, particularly for Microsoft 365, the damage is immediate.

Business email compromise Impersonating an executive or a trusted supplier to redirect a payment. No malware is involved, which is exactly why security tooling alone does not stop it.

Ransomware Modern attacks take a copy of your data before encrypting it, so backups answer the recovery question but not the threat to publish what they took.

Compliance as a Service

Our GRC platform tracks controls, evidence and obligations in one place, so compliance doesn't live in a spreadsheet nobody updates, and your next audit doesn't start from scratch.

Frequently Asked Questions

Got questions? We have answers.

What is the Essential Eight and does my business need to comply?

The Essential Eight is a cyber security framework developed by the Australian Cyber Security Centre (ACSC) that outlines the eight most effective mitigation strategies against cyber threats. While mandatory for many federal government agencies, it's increasingly expected by enterprise clients, insurers, and boards for businesses of all sizes. We assess your current Essential Eight maturity level and build a practical uplift roadmap.

What is a virtual CISO (vCISO) and do I need one?

A vCISO provides the strategic security leadership of a full-time Chief Information Security Officer without the cost of a permanent executive hire. InterIntra's vCISO service gives your organisation dedicated security strategy, risk management, board reporting, and compliance oversight, typically at 20-30% of the cost of an in-house CISO. It's ideal for businesses that need security leadership but aren't yet at the scale to justify a full-time hire.

How long does ISO 27001 certification take?

The timeline varies based on your starting maturity, but most organisations take 6-18 months from gap assessment to certification. The process involves implementing an Information Security Management System (ISMS), conducting internal audits, and then passing an independent certification audit. InterIntra guides you through every stage and can accelerate the process significantly if your IT fundamentals are already strong.

Working with InterIntra on our compliance framework was straightforward and practical. They understood the unique demands of healthcare and helped us build a security program that actually works for our team, not against them.
