Single Sign-On & Access Gateways
Fewer Logins.
Fewer Exceptions.
Fewer Headaches.
SSO and access gateways that simplify user access while giving leadership clear ownership, consistent policy, and confidence that "who can access what" has an actual answer.

Stop Access Fragmentation Before It Becomes an Incident
Access quietly breaks when every application handles identity differently and permissions drift over time. The impact shows up as reset tickets, slow onboarding, shadow accounts, and fragile workarounds - until it becomes an audit issue or a preventable security incident.
A single access layer fixes the root cause: one identity backbone, consistent policy, and predictable integration across SaaS, on-prem, and legacy systems. Applications don't need to be "modern" - where native SSO isn't available, a secure access layer is introduced to bring legacy and custom systems into the same identity and policy model without rewrites or disruption.
Here's what a unified SSO & gateway approach delivers:
- Centralised authentication using proven standards (SAML 2.0, OAuth 2.0, OpenID Connect) for consistent sign-in across applications
- Gateways in front of sensitive services to enforce policy before traffic reaches internal systems
- SSO enablement for legacy and custom applications by placing a secure intermediary layer in front of systems that lack native support
- Role-based and attribute-based access controls aligned to real responsibilities (least privilege by design)
- MFA and conditional access applied consistently, including modern factors (WebAuthn/FIDO2) where appropriate
- Automated joiner/mover/leaver flows to remove delays and eliminate lingering permissions
- Strong logging, audit trails, and optional SIEM integration to support investigations and compliance
- Directory and IdP integration (AD/LDAP/Entra ID/Okta and compatible providers) without duplicating identity data
If access is already creating drag, risk, or uncertainty, it is time to standardise it properly. Bring the applications, identities, and policies into one controllable layer - then roll it out with minimal disruption. Take Control of Access Now

Use Cases for Faster Sign-In and Clearer Control
Each use case is focused on reducing support load, tightening governance, and making access predictable at scale.
What You Get Out of the Box
Our SSO and Access Gateway solutions strengthen access control while improving user experience and reducing administrative burden.
-
Unified Login Experience
One secure authentication flow across applications, improving adoption and productivity. -
Centralised Identity Management
Consistent user lifecycle control with clearer policy enforcement and reduced admin complexity. -
Stronger Authentication Controls
MFA and conditional access reduce unauthorised access and limit credential-based attacks. -
Role-Based Access Control
Permissions aligned to roles, departments, and responsibilities - supporting least-privilege access by design. -
Auditability & Reporting
Clear logs and reporting that support investigations, compliance, and governance requirements. -
Directory Integration
Works with LDAP/AD and modern identity providers for continuity and reduced duplication.
Industry-Focused Access Architecture
Every industry has different pressures: compliance obligations, user populations, availability requirements, and legacy constraints. We design SSO and Access Gateway implementations around how access really works in your environment - from workforce identity and privileged admin access to third-party onboarding and audit reporting that stands up to scrutiny.
Healthcare
Secure, compliant access to clinical and administrative systems with strong auditing and role-driven permissions.
Telecoms
Controlled access to network tools, customer platforms, and operational portals - reducing risk while improving service continuity.
E-commerce
Safer customer and internal access journeys that protect payment systems and improve sign-in experience during peak demand.
Education
Seamless access for students and staff across learning platforms and admin tools, with simplified onboarding and offboarding.
Logistics
Stronger access governance for tracking, inventory, and fleet systems - keeping critical operations secure and available.
Manufacturing
Centralised control across live systems, OT-adjacent applications, and supply-chain systems - reducing operational disruption and limiting access exposure.
From Discovery to Delivery: Designed for Operational Confidence
We don't deploy generic identity stacks. Each SSO and Access Gateway solution is built around your technical environment, risk profile, and operational needs - so it stays reliable as your business grows.
-
Landscape Review & Requirements
We map your applications, user groups, identity sources, and authentication flows, then confirm what "good" looks like for security, usability, and compliance. Where needed, we also identify quick wins and high-risk systems that should be prioritised first.
-
Target Design & Rollout Plan
We define the access architecture, select the right open-source and/or proprietary components, and design policy foundations such as RBAC, MFA, and conditional access. You also get a phased rollout plan that reduces disruption, supports pilot groups, and makes onboarding predictable.
-
Build, Integrate & Validate
We deploy and configure the platform, integrate applications across cloud, on-premises, and legacy environments, and implement gateway controls for sensitive services. We then test sign-in flows, policy behaviour, logging, and failure scenarios to ensure the access layer behaves as intended.
-
Handover, Enablement & Support Options
We deliver documentation and practical knowledge transfer for your administrators and service desk teams, including repeatable steps for onboarding future applications. If you want us alongside you longer-term, we can provide ongoing monitoring, continuous improvement, and structured support through our SLA-Based Technical Support or Dedicated Support Hours.
Why Choose Onyxsis?
Operational Gains, Backed by Reality
Practical improvements teams notice every day.
Our work is grounded in real operational outcomes. In the Unified Access Connector delivered for a UK telecommunications provider, we reduced access friction without disrupting legacy systems - cutting time spent managing access by 34% while reliably handling 40 million+ web requests per day.
Those results matter because they reflect how we work: minimise disruption, focus on what slows teams down, and deliver changes that improve day-to-day operations immediately. If you need to modernise around legacy constraints without losing momentum, you're in the right place.
