Enterprise Identity & Access Infrastructure.
Zero-trust authentication, authorisation, and credential management for institutions where access is a regulated control surface.
Overview
Identity is the control surface that sits in front of every other control.
XVICA builds identity and access infrastructure for workforce, customer, partner, and machine populations across heterogeneous estates. The architecture is zero-trust by default: every request is authenticated, authorised, and audited regardless of network location, session history, or prior trust. Integrations land on existing identity providers and directories so existing systems of record remain authoritative while the control surface strengthens.
Perimeters have dissolved. Access has not.
Breach analysis over the last five years is consistent on one point: credential compromise and access misuse account for the majority of material incidents. The controls that prevent them (strong authentication, scoped authorisation, privileged access management, continuous session evaluation, and timely revocation) are well understood. The hard part is operating them at institutional scale across legacy and modern stacks without breaking what works.
Regulators have caught up. NIS2, DORA, the PRA’s operational resilience rules, and sector-specific regimes now require demonstrable identity assurance, phishing-resistant authentication for privileged access, and evidenced entitlement review. Treating identity as infrastructure (specified, engineered, operated under SLA) is how institutions meet those obligations without adding friction for the populations that matter.
What we build
Every capability is specified, integrated, and operated as part of a single identity platform. Components are delivered individually or as a programme.
Authentication
Multi-factor, passwordless, and FIDO2/WebAuthn flows with phishing-resistant options for privileged populations.
Authorisation
Fine-grained RBAC and ABAC with policy-as-code, continuous evaluation, and context-aware decisions.
Identity federation
SAML, OIDC, WS-Federation, and SCIM integration with Entra ID, Okta, Ping, ADFS, and directory systems.
Credential management
Secure credential issuance, rotation, and revocation with HSM-backed key material and documented recovery.
Privileged access
Just-in-time elevation, brokered session recording, and break-glass procedures with independent audit review.
Access intelligence
Real-time anomaly detection, entitlement certification, and risk-based step-up tied to the broader SOC pipeline.
How we build identity systems
Identity sits in front of every other control. We focus on predictable enforcement, clear ownership, and evidence that access is provisioned, changed, and revoked in line with policy and regulation, not just at design, but every day in production.
Threat-informed architecture
We map the estate, classify populations, and threat-model every authentication and authorisation flow. Compliance obligations are translated into explicit control requirements.
Zero-trust foundation
No implicit trust, ever. Every request is authenticated and authorised with context (device posture, location, behavioural signals) at the decision point, not only at session start.
Integration and migration
We migrate from legacy IdPs and directories without downtime, preserving existing systems of record while strengthening the control surface in front of them.
Continuous assurance
Ongoing monitoring, threat detection, entitlement review, and scheduled attestation. Controls are tested under simulated attack, not only paper-reviewed.
Technical standards
Zero-trust architecture
Continuous verification with no implicit trust on network location.
99.999% authentication uptime
Geo-distributed, independently failing regions with session portability.
Sub-50ms decisions
Authorisation at the pace of user experience and machine traffic.
FIDO2 / WebAuthn
Phishing-resistant authentication for privileged populations by default.
NIST SP 800-63-3
Identity, authenticator, and federation assurance explicitly scored and documented.
SOC 2 and ISO 27001 aligned
Controls mapped from specification, evidenced continuously.
Identity patterns we deliver
Four canonical deployments. Specifics vary by estate, population, and regulatory regime.
Employee access at scale
SSO, MFA, lifecycle management, and automated provisioning tied to the HR system of record. Joiners, movers, and leavers are handled declaratively, with entitlement drift surfaced for review rather than accumulating silently.
CIAM for millions
Scalable customer identity with frictionless authentication, progressive profiling, consent management, and compliance with UK GDPR and sector-specific rules. Account recovery is designed with fraud and usability weighed together.
B2B federation
Cross-organisation federation with just-in-time provisioning, delegated administration, and scoped entitlements. Third-party access is time-bounded and revocable without coordination calls.
Service and workload identity
Workload identity for containerised and cloud-native environments, short-lived credentials for service-to-service communication, and centrally governed API authentication with SPIFFE/SPIRE-compatible patterns where appropriate.
Security posture
Defence in depth
Multiple enforcement layers with no single point of failure or trust.
Continuous monitoring
Behavioural baselines with real-time anomaly detection and response.
Compliance ready
Full audit trails, entitlement reports, and examiner-ready evidence.
Incident response
Documented playbooks, tested recovery procedures, and blameless reviews.
Where identity is a control surface
Financial Institutions
Workforce, customer, and counterparty identity for banks, insurers, and market infrastructure.

The questions that come up most often during briefings.
What does enterprise identity and access infrastructure cover?
Authentication, authorisation, credential lifecycle, privileged access management, federated single sign-on, and audit-grade session logging. The architecture is zero-trust by default: every request is verified regardless of network location or prior authentication state.
Do you integrate with existing IdPs and directories?
Yes. We integrate with Entra ID, Okta, Ping, ADFS, and LDAP-based directories via SAML 2.0, OIDC, SCIM, and WS-Federation. Hybrid deployments that maintain existing IdPs as the system of record are common.
How is privileged access handled?
Privileged access is brokered through short-lived credentials, just-in-time elevation, and session recording. Break-glass procedures are documented and tested, with independent audit review.
Which identity standards do your systems align with?
NIST SP 800-63-3 (IAL/AAL/FAL), FIDO2/WebAuthn for phishing-resistant authentication, OAuth 2.1, and OIDC. Controls are mapped to SOC 2, ISO 27001, and sector-specific regimes (HIPAA, PCI-DSS, CJIS) as required.
What does a typical engagement timeline look like?
Greenfield IAM platforms typically move from specification to first production deployment in four to seven months, with staged rollout to remaining populations over a further six to nine months. Existing-platform hardening engagements are shorter.
