Most breaches don't start with broken code — they start with a person having a bad day. Chain Cybersecurity combines behavioural security training with hard technical controls so your organisation is resilient in practice, not just on paper.

Work aligned to the standards your auditors and customers ask about
Capabilities
Advisory, technical testing, monitoring and training — delivered by senior practitioners and reported in language your whole team can act on.
Our core discipline. Culture assessments, role-based training paths and continuous phishing, smishing and vishing simulations that measurably change behaviour.
Continuous monitoring across endpoint, identity, cloud and network with triaged alerts, containment playbooks and a named analyst — not a ticket queue.
Infrastructure, web, mobile, API and cloud testing, plus adversary-simulation exercises mapped to MITRE ATT&CK with retest included.
Gap analysis, ISMS build-out, policy sets, risk registers and audit support for ISO 27001, NIS2, SOC 2 and GDPR — including evidence packs.
Least-privilege design, MFA and phishing-resistant authentication, privileged access management and joiner-mover-leaver hygiene.
Configuration review and hardening for Microsoft 365, Azure, AWS and GCP, network segmentation and continuous posture management.
Retained response capacity, containment and eradication, forensic timelines, regulator and data-subject notification support, and post-incident reviews.
Threat modelling, secure code review, SAST/DAST/SCA in the pipeline and secure SDLC coaching for your engineering teams.
Vendor due-diligence frameworks, questionnaire automation, contractual security requirements and a supplier register that survives an audit.
Also delivered as standalone engagements
Human risk management
Annual click-through e-learning satisfies an auditor for a day. We build a measurable security culture: baseline it, target the weakest workflows, then prove the improvement with data you can put in front of a customer or an auditor.
Behavioural survey, culture interviews and an unannounced simulation to find where risk actually lives.
Short, role-specific modules for engineering, support, operations and leadership — in the language they work in.
Rolling phishing, credential-harvesting, MFA-fatigue and voice-pretexting scenarios modelled on current attacker tradecraft.
Department-level dashboards, trend lines and coaching for repeat-risk groups. No naming and shaming.
Who we work with
The fundamentals don't change between sectors, but the crown jewels do. We start by understanding what would hurt most if it went down or got out, then work backwards.
Multi-tenant isolation reviews, control-panel and hypervisor hardening, customer data segregation, abuse handling and DDoS readiness — plus the security answers your own clients keep asking you for.
Secure SDLC coaching, API and tenant-isolation testing, cloud posture management and SOC 2 or ISO 27001 readiness so enterprise procurement stops blocking your deals.
Protection for special-category personal data, access control across shared clinical systems, supplier assurance and staff training that respects clinical workflow.
OT and IT segmentation, ransomware resilience for operations that cannot stop, remote-access hardening and NIS2 scoping for essential and important entities.
Client confidentiality, defence against email compromise and impersonation, secure collaboration with external parties and safe remote working.
Awareness programmes that scale to very large user populations, legacy estate hardening and pragmatic roadmaps for teams working under real constraints.
Not on the list? The methodology is sector-agnostic. If your organisation holds data worth stealing, depends on systems staying up, or answers to a regulator or a customer's security questionnaire, it applies to you.
Compliance & assurance
We map every recommendation back to the obligation that drives it, so security work is traceable to a requirement — and audit season stops being a fire drill.
ISMS design, scoping, risk treatment plans, internal audit and certification-readiness support.
Applicability analysis, governance and management-accountability duties, incident reporting and supply-chain measures.
Trust services criteria mapping, control design, evidence collection and Type I or Type II readiness.
Technical and organisational measures, DPIAs, breach response procedures and processor assurance.
Maturity scoring and prioritised roadmaps when you need a practical baseline rather than a certificate.
Questionnaire and due-diligence support, trust documentation and control evidence for the clients assessing you.
Chain Cybersecurity provides advisory, testing and training services. We help you prepare for and evidence compliance; formal certification and attestation are issued by accredited third parties.
How we work
Two-week discovery: technical review, control mapping and behavioural baseline. You get findings ranked by real business impact.
A roadmap sequenced by how much risk each step removes for the effort it takes — quick wins first, structural work planned honestly.
We work alongside your team, configure with them and document as we go, so capability stays in-house.
Ongoing monitoring, recurring simulations and quarterly reviews that keep the posture score moving in one direction.
We sell no licences and take no reseller commission. The recommendation is the recommendation.
Every report ships with a technical annex and a one-page version a non-technical reader can decide on.
Registered in the Netherlands, with engagement data held in the EU under GDPR.
Enquiries answered within one business day; retainer clients get agreed response windows in writing.
FAQ
Scoping calls are usually available within a few working days. A baseline assessment typically begins within two to three weeks of a signed scope, and incident-response support for retainer clients starts immediately.
Hosting and managed service providers, SaaS and technology platforms, healthcare, logistics and industry, professional services, education and public bodies. Size is not the deciding factor — the deciding factor is whether you hold data worth stealing or depend on systems staying available.
No. Engagements scale from a single training programme or one-off penetration test up to a full virtual-CISO relationship. Smaller organisations often get the most value from the assessment-plus-roadmap package.
Every engagement runs under a written scope, rules of engagement and an agreed escalation contact. Destructive techniques are excluded unless explicitly authorised in writing, and critical findings are reported immediately rather than held for the final report.
Short role-based modules (typically 10–15 minutes), live workshops for high-exposure teams such as support and operations, tabletop exercises for leadership, and continuous simulations. Results are reported at group level to build trust, not fear.
Mutual NDAs are standard before scoping. Findings are shared only with your named contacts, evidence is stored encrypted in the EU, and data is deleted on an agreed schedule after delivery.
