Cloud, platform and AI security

Three ways we work with you, from a fixed-scope assessment through to running your cloud security alongside your team.

Consulting & Advisory

Expert advice at every stage of your cloud journey. From platform security design to securing AI workloads. Delivered by senior experts who build the solutions alongside your team.

Cloud Security Strategy

You can spend as much money and effort on cloud security as you want and there will still be residual risk, so what a strategy has to answer is where the next investment reduces the most risk, and whether the business is comfortable with what is left.

Cloud Security Architecture

Once teams start building on a cloud platform, its security model becomes expensive to change, so we would rather help you get it right while it is still a design, and then stay involved while it is being built.

Cloud Security Engineering

The same engineers who run our assessments, available for ongoing work rather than for a fixed-scope project. There is no defined deliverable at the end of it, so you decide what they spend their time on.

Cloud Security Manager

Cloud Security Manager focuses the on people, processes, business, and strategy, which is an essential part of your transformation journey.

Platform Engineering

Whatever you build into a platform, every team that uses it inherits, which is the argument for doing the security work at the platform layer rather than project by project.

Security Tooling

Security tools tend to get bought on the strength of a demo, configured once, and then left alone. We can help you choose the right ones, get them properly working, and stop paying for the ones you have stopped using.

Application Security

Your developers make security decisions in code review and in design meetings that we are not part of, and this is the class that helps them make those decisions well, using their own systems as the material.

AI Agent Security

An agent with tool access is effectively a user with credentials and no judgement about who is asking, and most of them have been given a good deal more access than the job actually needs.

Explore service→

Training & Enablement

Your team makes these decisions every week, mostly without us in the room, so at some point it is more useful to teach them than to keep answering the questions ourselves.

Assessments

All assessments →

Identify risks across your digital estate, uncover weaknesses, and walk away with a tailored improvement plan you can act on.

Cloud Security Assessment

Most of what we find in a cloud environment is not a single misconfiguration, but a combination of identity, configuration and exposure that no tool flags on its own. This assessment finds those combinations and tells you which ones to prioritize.

Explore service→

Cloud Penetration Test

A penetration test that starts from a credential someone has already stolen, and establishes what an attacker could actually do with it in your environment rather than what they might theoretically be able to do.

Explore service→

Cloud Application Security Test

Applications that are built upon native cloud functionality have fundamentally different attack surfaces and threats than traditional application architectures.

Explore service→

Kubernetes Security Assessment

We assess whether the boundaries inside your cluster hold, between tenants, between workloads, and between the cluster and the cloud account it runs in.

Explore service→

AI & Agent Security Assessment

Most organizations cannot say how many agents they are running, who owns them, or what those agents have access to. This is a fixed-scope assessment of the ones you already have, and it starts by finding them.

Managed Services

Continuous coverage of your cloud estate. We monitor, remediate, and operate alongside your team.

Managed Cloud Security

Continuous cloud security coverage. We monitor, remediate, and operate alongside your team across Starter, Advanced, and Enterprise tiers.

Customer stories

For a leading maritime operator like Fjord Line, maintaining seamless digital operations is mission-critical. Upon joining as Head of Digital Security (CISO) in May 2022, Kim Bruland launched a strategic initiative to modernize the company's security posture. Recognizing the need for specialized expertise, Fjord Line partnered with O3 Cyber (O3C) in early 2023. What began as a collaborative effort has evolved into a seamless integration, with O3C serving as an extension of Fjord Line’s internal team through their continuous Managed Cloud Security service.

O3 Cyber delivered a two-day threat modeling class and workshop for our employees, providing high-quality content and engaging practical examples. This allowed our employees to learn the basics of threat modeling quickly and efficiently. The workshops not only facilitated learning but also kickstarted our internal threat modeling initiative, showing us how we could apply our newfound knowledge to our own systems.

O3C's approach to cybersecurity centers on a fundamental belief: they have a genuine interest in the customer's success. Coop Norway discovered this firsthand, recognizing a true partner dedicated to building a comprehensive cloud security approach tailored to Coop's needs and vision.
