About
Built in Sydney to get ahead of scammers.
Australians reported A$2.18 billion lost to scams in 2025 (ACCC). Many of those scams start with something that looks like a brand people trust: a bank's sign-in page, a toll notice, a supplier's invoice. Sixth finds those fakes early and works to get them removed.
Who we are
A small team, working with AI agents.
Sixth is a product of Yathra, a Sydney technology company that builds and runs IT systems for Australian businesses.
AI agents do the repetitive work of watching, checking and chasing. Our people make the decisions and look after our clients. That's how we can offer protection that used to need a large team of experts, at prices mid-sized organisations can afford.

Where we are
What runs today, and what comes next.
The main parts of Sixth. When something ships, it moves across on the day. The whole roadmap Security and data
Running today
- Lookalike WatchWe compare every new website with 156 Australian brands and flag the copies the day they're set up.
- AI verdictsAI judges every lookalike. In our latest test it agreed with our reviewers on 95.5% of 157 decided cases and dismissed none of the 25 real fakes.
- TakedownsWe ask the company hosting a fake, and the one its address was bought from, to remove it, and follow up until it's gone. AI reads their replies.
- Alerts with the evidenceAn email to your team for each confirmed fake, with the screenshot and a PDF of the evidence.
- Blocking listYour firewall or DNS filter fetches a live list of your confirmed fakes from a private link and blocks them. Each case shows when your tools last fetched it.
- Scam CheckForward a suspicious email or a screenshot of a text and get an answer in about a minute. Open to our invited trial group.
- Monthly recordEmailed to you as a PDF on the 1st of each month, for your board and regulator: what we found, what we asked to be removed, and how long each fake stayed up. Built for the Scams Prevention Framework.
- Logins for your teamYour people sign in with their own email to see every confirmed fake of your brand, its evidence and progress, this month's numbers and your monthly records. They can tell us a site is yours or ask about a case.

- Self-serveYour own team deciding cases in the Sixth console, if you choose self-serve. Today our analysts work every case.
- GuardianGuardian will watch a parent's bank account for the payments scammers ask for, and alert someone they trust.
- Takedowns in your name PlannedRequests sent in your organisation's name under a letter of authority, and trade-mark requests against lookalikes before anything harmful goes live.
- AI in Australia PlannedWe'll run our AI models through AWS in Sydney and Melbourne, so what they read stays in Australia. Today they run outside Australia, mainly in the United States.
- Industry sharing PlannedEvery confirmed fake shared through the anti-phishing industry's exchange, so email providers and security companies block it too.
- ISO 27001 and the Essential Eight PlannedCertification and an assessment against the Australian Government's Essential Eight, so your security team has the evidence it asks for.
