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.
We help sovereign teams strengthen national-scale incident coordination, automate threat intelligence sharing, and mature critical infrastructure protection capabilities.
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.
We help product security teams establish structured vulnerability handling — automating triage, coordinating disclosure, and integrating advisories into your development lifecycle.

Assess your current SOC maturity, identify gaps in people, processes, and technology, and build a roadmap to improve your security operations.
Recruit, train, and stand up a new security operations team with the right structure, skills, and tooling from day one.
Automate detection, triage, and response workflows across your SIEM, SOAR, and EDR to increase speed and reduce analyst fatigue.
Map your detection capabilities to the MITRE ATT&CK framework and identify coverage gaps across tactics and techniques.
Connect your SIEM, SOAR, EDR, and other security tools into a cohesive operations workflow.
Prepare and guide your organisation through the FIRST.org membership process and SIM3 assessment.

Security operations (SecOps) is the people, processes and tools that keep an organisation monitored and defended day to day — detecting threats, investigating alerts, responding to incidents and continuously improving. A SecOps or SOC team runs monitoring and triage, incident response, threat hunting and detection engineering. Cosive helps you start, run and improve security operations with independent, engineering-led advice.
SOAR (Security Orchestration, Automation and Response) is a category of platform that connects your security tools together and automates the workflows between them — enrichment, triage, ticketing and response — so routine steps happen in seconds instead of minutes. It cuts alert noise and frees analysts for the judgement calls only people can make. Cosive helps teams adopt SOAR pragmatically.
SIM3 (Security Incident Management Maturity Model) measures how mature an incident-response capability is across four areas: organisation, human, tools and processes. It's the model used to benchmark CSIRTs and prepare for FIRST membership or TF-CSIRT accreditation. Cosive runs SIM3 assessments — benchmarking your team, identifying gaps and building a remediation plan aligned to those requirements.
We assess your security operations with the SIM3 maturity model across four dimensions — organisation, human resources, tools and processes — giving you a clear picture of where you stand, where the gaps are, and a prioritised roadmap you can take to the board. We also work with SOC-CMM where it fits your goals.
We use threat modelling to pinpoint the adversaries, techniques and attack vectors most relevant to your sector and infrastructure, then map your coverage to MITRE ATT&CK so you can see exactly where detection is strong and where to invest next. See how we help with using the ATT&CK framework.
Yes — we integrate your SIEM, SOAR, EDR, threat intelligence platforms and ticketing systems into one connected workflow. Our approach is vendor-neutral: we get more value from what you already run rather than pushing replacements. See how we build and integrate security operations tools.
Yes. We've built CSIRTs at national, sector and organisational levels across government and critical infrastructure — covering team structure, processes, tooling and training, and guiding you through SIM3 assessment and FIRST membership once you're operational. See how we help you start a new security operations team.
We guide you through the whole process — from a gap analysis against the entry requirements to building the processes and documentation the review committee expects. Our team includes FIRST.org advisors who know exactly what acceptance takes. See how we help you join FIRST.
Frame it in terms the board understands: risk reduction, incident-response times, detection-coverage percentages and benchmark comparisons against peers. A mature SOC is a measurable reduction in organisational risk, and we help you build that business case with hard numbers from your maturity assessment.
