Cyber Security Operations

We help you build, run, and improve your security operations to protect what matters most to your organisation.

Select your goal

SOCs

We assess your maturity against established frameworks, identify detection gaps, and build a prioritised roadmap focused on reducing response times through automation and tooling integration.

Maturity Assessment Detection Engineering Automation Playbook Development

National CSIRTs

We help sovereign teams strengthen national-scale incident coordination, automate threat intelligence sharing, and mature critical infrastructure protection capabilities.

SIM3 Maturity Threat Sharing Platforms Capacity Building Incident Playbooks

Industry ISACs

We support industry-specific security teams with sector-wide benchmarking, coordinated exercise planning, and building the information-sharing communities that connect national and enterprise levels.

Sharing Communities Platform Deployment Member Onboarding Governance

PSIRTs

We help product security teams establish structured vulnerability handling — automating triage, coordinating disclosure, and integrating advisories into your development lifecycle.

How we work

What working with us looks like

We're independent and unbiased. We're not your MSSP or one of your usual vendors, so we can honestly assess what's working, what isn't, and where your investment should go next.
Every recommendation is actionable. Instead of bloated reports that gather dust, we deliver prioritised, realistic steps your team can execute on immediately.
We adapt to your situation. Your team size, budget, threat landscape, and regulatory context shape every engagement.
We build your capability, not a dependency. Upskilling your people throughout so improvements stick after we leave.

Questions we hear from security leaders

How do you assess our current SOC maturity?
We use the SIM3 maturity model to assess your security operations across four dimensions: organisation, human resources, tools, and processes. This gives you a clear picture of where you stand, where the gaps are, and a prioritised roadmap you can take to the board.
How do I prioritise which threats to focus on?
We use threat modelling to identify the adversaries, techniques, and attack vectors most relevant to your sector and infrastructure. Combined with ATT&CK mapping, this shows exactly where your detection coverage is strong and where to invest next.
We have multiple security tools that don't talk to each other — can you help?
We integrate SIEM, SOAR, EDR, threat intelligence platforms, and ticketing systems into a connected workflow. Our approach is vendor-neutral — we optimise what you already have rather than pushing replacements, so your team gets more value from existing investments.
Can you help us stand up a new CSIRT?
Yes. We've helped build CSIRTs at national, sector, and organisational levels across government and critical infrastructure. We cover everything from team structure and processes to tooling and training, and can guide you through SIM3 assessment and FIRST membership once the team is operational.
What's the fastest path to FIRST membership?
We guide you through the full process — from gap analysis against entry requirements to building the processes and documentation needed for acceptance. Our team includes FIRST.org advisors who understand exactly what the review committee looks for.
What does a SIM3 assessment involve?
SIM3 measures your incident response maturity across four areas: organisation, human, tools, and processes. We benchmark your team against the model, identify gaps, and build a remediation plan aligned with FIRST membership or TF-CSIRT accreditation requirements.
How do you ensure improvements stick after you leave?
We upskill your team throughout every engagement, not just at the end. Knowledge transfer, documented playbooks, and hands-on mentoring mean your people can sustain and build on improvements independently. We build your capability, not a dependency.
How do I make the case for security operations investment to the board?
We help you frame security operations in terms the board understands: risk reduction, incident response times, detection coverage percentages, and benchmark comparisons against peers. A mature SOC isn't a cost centre — it's a measurable reduction in organisational risk.
