Built for teams that want to move fast without cutting corners

Whether you're a seed-stage startup shipping your first product or an established company whose AWS bill has quietly gotten out of hand, the same two problems keep showing up: nobody has time to audit the architecture properly, and nobody is watching it day to day.

Any stage, any size

From pre-seed to Series C and beyond, the review scales to the size of your actual AWS footprint, not a one-size-fits-all package.

Built to lower your bill

Every review includes a cost pass. Most engagements pay for themselves in avoided waste before you even factor in the security upside.

Senior engineers only

No account managers relaying your questions. You work directly with the engineer doing the work, on every call.

How an AWS security review works

Two steps, no jargon: we find what's wrong first, then make sure it stays fixed.

01

Rigorous security audit

We map your AWS environment end to end, identify gaps against the Well-Architected Framework, and hand you a prioritized roadmap before your next customer security review.

02

Continuous security monitoring

Ongoing security operations keep the gaps a review closes from quietly reopening, while your team focuses on shipping product.

Transparent service plans

Four clear options, priced in AUD. No hidden fees, no long-term lock-in on the review.

What clients say

Real feedback from people we've worked with.

“Alex is highly knowledgeable across cloud infrastructure and security, with a very practical and hands-on approach. He took the time to explain things clearly and was even happy to answer follow-up questions a month after our call! I'd happily recommend Alex to any business looking for security expertise!”
SashaCTO, AirEstate
“We had a bit of a scare when one of our developer's AWS access keys was accidentally exposed in a public GitHub repository. Alex was onto it within the hour and helped us rotate the credentials, secure the account, and put AWS WAF in place to better protect our exposed services. Since then, he's continued monitoring our AWS environment and keeping an eye on any security issues that come up. It's reassuring knowing someone experienced is looking after things rather than us finding out about a problem after it's already happened.”
