You probably pay for AWS security. Do you use it?
Green Custard helps you turn AWS security tooling already in your account into a measured, well governed security posture. Native first, vendor neutral, and built on the tools you already have.
The cloud provider secures the platform.
The rest is on you.
AWS gives you world class security tooling. Whether it is configured, monitored, and kept in good order is your responsibility, not theirs. That is where most risk actually lives, and it is rarely a sophisticated attack. It is usually a setting.
99% of failures are the customer's fault
99% of cloud security failures through 2025 are expected to be the customer's fault, not the cloud provider's.

82% of problems are human error
Around 1 in 4 cloud security incidents trace back to a misconfiguration, and 82% of those misconfigurations come down to human error, not a flaw in the software.

We are not another security vendor. We are the partner who gets your AWS security right.
You do not need more tools layered on top of AWS. You need the security capabilities inside AWS, things like Security Hub, GuardDuty, Control Tower, and IAM, configured correctly, governed properly, and reviewed on a regular basis.
That is consulting and engineering work, not a product sale. We are vendor neutral by design. Where a specialist tool genuinely adds value, we will recommend it, but our starting point is always the capability you already have in your accounts.
Native first We start with the AWS security services already in your account, so you get value from spend you have already committed.
Vendor neutral No product agenda. Our recommendations are based on your posture and your risk, not a reseller quota.
Governance, not guesswork We set up guardrails and a repeatable review rhythm, so good security posture holds over time instead of drifting.
The AWS security tooling we put to work
All part of AWS Security, Identity and Governance. Most accounts have these available and underused.
Start with a Security Baseline Assessment
A focused review of your AWS security posture against the AWS Well-Architected Framework Security Pillar. You get a clear findings report and a prioritised remediation roadmap, so you know exactly where you stand and what to fix first.
It is a conversation, not an audit, and it is designed to be light on your team's time. It is a low-commitment way to get a clear, expert read on your security posture before deciding what, if anything, to do next.
What you get:
- A posture review against the Well-Architected Security Pillar
- A written findings report, prioritised by risk
- A remediation roadmap you can act on, with or without us
What a Well-Architected review actually involves
The AWS Well-Architected Framework is the same lens AWS uses to review systems internally. Our assessment runs your workload against the Security Pillar: identity and access, data protection, detection, infrastructure protection, and incident response.
It is deliberately lightweight, hours of your team's time, not weeks. We work through a structured set of questions with you, flag the issues that matter most, and hand back a prioritised view of high, medium, and low risk findings with clear recommendations.
Sepura Well-Architected Review
"The review process was more streamlined than our previous review with another partner, as Green Custard provided a light-weight pre-review questionnaire and then explored our environment in detail rather than us having to walk through the structure. Having a live working document as the report where we could discuss remediation was very useful."

Specialist Engineer
From a one-off check to security that stays in good shape
The assessment is the start, not the end. Once we know where you stand, there is a clear, optional path forward, and you choose how far along it you want to go.
Three stages:
1. Assess Security Baseline Assessment. Findings and a roadmap. You know exactly where you stand.
2. Govern We set up the foundations: Control Tower guardrails, Security Hub, IAM hardening, the controls that stop problems recurring.
3. Operate An ongoing managed service. We monitor your security posture, run regular reviews, and keep things from drifting, so security holds without you building an internal team for it.
No lock-in at any stage. Most customers start with the assessment and decide from there.
What good looks like
Fewer surprises. Continuous visibility of your security posture, so issues surface as findings, not incidents.
Faster to fix. The longer a problem goes undetected, the more it costs. Industry data puts the average time to find and contain a breach at 241 days. A monitored posture closes that gap.
Spend that works harder. You get real value from AWS security tooling you are already paying for, instead of leaving it switched off.
Case Study: Secure, governed cloud platform for an inter-dealer broker
Challenge
Oil Brokerage run a business-critical trading platform on AWS, handling confidential trade and counterparty data where security and availability are non-negotiable. As they scaled, they needed a partner to own day-to-day operational excellence and the security posture of the environment, so leadership could focus on commercial growth, not infrastructure governance.
What we did
A managed service built on native AWS controls. Continuous security posture management with Security Hub as the central control plane, codebase vulnerability scanning, observability and monitoring, tested backup and disaster recovery, and an annual independent review against all six pillars of the Well-Architected Framework, including the Security Pillar.
Result
A production AWS platform with a continuously assured security posture, findings triaged centrally, the codebase kept current, backups tested, and the whole estate independently audited each year. Named accountability and defined SLAs, without Oil Brokerage needing to build an in-house security and operations team.
"This WAFR process made us aware of the security loopholes present in our ecosystem and we took this as an opportunity to streamline and tighten the gaps in infrastructure security. Thanks to the Green Custard team for timely followup on the HRI resolution and clear action items on mitigation of the risk items."
Amey Kulkarni, Koko Networks
"Always a pleasure to work with, very straightforward and always felt like talking to an extension of our own team. An actual example of 'partners' rather than suppliers. Thank you."
