Zero-Trust Security Infrastructure.
Defence in depth from identity to workload to data. Built, operated, and evidenced to institutional standards rather than retrofitted at the end.
Overview
Security is an engineering property. It is not a team, a tool, or a paper framework.
XVICA builds security infrastructure the way we build every other regulated system: specified up front, controlled in version, tested continuously, and operated with evidence. Zero-trust is the default posture; identity and workload boundaries are explicit; key material is HSM-backed; detections are authored as code; and incident response is rehearsed before it is needed.
Security is now a regulatory deliverable.
DORA, NIS2, PRA SS2/21, the FCA’s operational resilience rules, HIPAA, and sector-specific regimes have turned security posture into an evidenced deliverable rather than a risk commentary. Supervisors expect documented controls, tested under simulated attack, with independent assurance and prompt incident notification.
Institutions that treat security as an engineering concern (controls as code, detections as code, evidence as code) close findings faster, retain examiner confidence longer, and reduce the gap between policy and operational reality. The work we do is explicit, measurable, and continuous.
What we build
Security components are delivered individually or as a single platform across identity, workload, data, and monitoring layers.
Zero-trust architecture
Identity-aware proxies, continuous authorisation, mutual TLS, and explicit workload identity. No implicit network trust.
Key and secret management
HSM-backed key hierarchy with documented rotation, quorum-controlled recovery, and per-tenant isolation.
Encryption everywhere
Transport, storage, and application-level encryption with FIPS 140-2 validated modules.
Detection engineering
Detections authored as code, unit-tested, peer-reviewed, and exercised against simulated attack traffic.
Incident response
Documented playbooks, tabletop exercises, signed chain-of-custody evidence, and post-incident review integrated with engineering.
Compliance and attestation
Control evidence collected continuously for SOC 2, ISO 27001, PCI-DSS, and HIPAA rather than assembled retrospectively.
How we build security infrastructure
Security engineering shares the same discipline as the rest of the platform: specification, version control, testing, observability, and independent review.
Threat-informed architecture
We model the estate and its adversaries, then design controls against real attack paths rather than generic checklists. Threat models are living documents, not one-off deliverables.
Controls as code
Access policy, detection logic, configuration baselines, and evidence collection are expressed in version control with peer review.
Verified under attack
Synthetic adversary simulation runs on schedule. Red-team findings land in the same backlog as engineering work. Gaps are closed, not rationalised.
Operated with evidence
Control effectiveness is measured continuously. Quarterly attestation draws on live evidence rather than screenshots and point-in-time samples.
Technical standards
Zero-trust by default
No implicit trust based on network location or prior session.
FIPS 140-2 cryptography
HSM-backed key material with audited lifecycle.
NIST 800-53 moderate baseline
Control set mapped and evidenced; higher baselines for public-sector work.
MITRE ATT&CK aligned
Detection coverage scored against the framework, tracked over time.
SOC 2 Type II and ISO 27001
Annual independent attestation from specification.
Cyber Essentials Plus
Maintained where public-sector work requires it.
Where organisations deploy this
Representative deployments. Specific client references are covered under NDA during briefings.
DORA-aligned security operating model
A pan-European bank redesigned its security operating model to the DORA standard: ICT risk framework, incident classification, third-party dependency register, scenario testing, and board-level reporting, implemented on code-authored controls and evidence collection.
Secure by Design for a digital service
A government department delivered a public-facing digital service under the NCSC Secure by Design principles with threat modelling, continuous assurance, and accredited infrastructure. Service assessment was supported by live evidence rather than paper artefacts.
Clinical data protection at regional scale
A healthcare network hardened its data platform to DSPT standards with tokenisation at ingest, role-scoped access, continuous monitoring, and documented incident response. Audit cycle time dropped from weeks to days.
Engineering rigour on security
Zero implicit trust
Every request authenticated, authorised, and audited with context.
Detection as code
Version-controlled, peer-reviewed detections tested against simulated attack.
Evidence on demand
Continuous control evidence; examiner packs produced in minutes, not weeks.
Rehearsed response
Incident playbooks exercised under realistic conditions, not only in runbooks.

The questions that come up most often during briefings.
What does zero-trust security infrastructure include?
Identity-aware access proxies, mutual TLS for service-to-service communication, continuous authorisation evaluation, workload identity, secrets management, HSM-backed key management, centralised logging with tamper evidence, and monitored response workflows.
How do you approach detection and response?
Detection engineering runs as code: rules are written, tested, and reviewed in version control. Findings are triaged through documented runbooks with SLAs tied to severity. Post-incident reviews are structured and blameless, with controls updated in the same change management system as product features.
Which certifications and frameworks do you align with?
SOC 2 Type II, ISO 27001, ISO 27017 and 27018 where cloud-relevant, PCI-DSS, HIPAA, CIS benchmarks, NIST 800-53 and 800-171, FIPS 140-2 for cryptographic modules, and Cyber Essentials Plus for UK public sector work.
Do you provide managed security operations, or only build it?
Both. We build the platform and transfer it, or we build and operate it under SLA as part of a longer engagement. Managed operations include detection engineering, incident response, threat hunting, and quarterly control attestation.
How do you verify controls are actually working?
Control assurance is continuous: synthetic attack simulations run on schedule, control evidence is collected automatically, and independent audits run annually. Findings are tracked to closure in the same backlog that governs engineering work.
