Hybrid & Legacy Security
Security for IT estates that were not built from a blank slate.
Enterprise IT rarely consists solely of modern cloud services. On-premise infrastructure, Active Directory, specialized applications and legacy systems often remain business-critical.
Established infrastructure is normal.
Enterprise environments develop over many years. Different systems serve different purposes and cannot always be replaced or standardized at short notice.
The relevant basis is therefore not an idealized target architecture, but a security assessment that accounts for the actual infrastructure and its access paths.
Assessment
Where security gaps can emerge.
- Different authentication methods
- Inconsistent access policies
- Systems that cannot readily be migrated
- Hybrid identity models
- Administrative dependencies between systems
Security without rebuilding the entire environment.
Security controls should fit where existing systems, applications and identities are already connected. Not every environment can or needs to be rebuilt in full.
VIREON helps structure requirements for suitable security solutions in the context of the existing infrastructure.
Hybrid access
Assess cloud and on-premise together.
Identities and access frequently cross platform boundaries. Cloud services, on-premise systems and internal applications can share users, permissions or trust relationships.
Security requirements become clearer when these transitions are assessed along the actual access paths.
Typical relevant environments.
- Active Directory connected to Entra or other cloud environments
- Internal business applications
- Legacy applications and specialized systems
- Administrative systems and privileged access
- Mixed authentication infrastructure
