cybr:co’s legacy foundations and modernisation capability recognises that critical business services still rely on core technologies that are often overlooked in modern transformation programs. We bring deep technical expertise across Microsoft on-premises environments, including Active Directory, PKI, DNS, DHCP, and related foundational infrastructure. These platforms underpin identity, security, and operational stability, and we understand the importance of maintaining and securing them while organisations evolve toward modern architectures.

We help organisations assess, secure, and stabilise existing legacy environments, applying modern security practices to improve resilience and reduce risk without disrupting operations. Whether strengthening directory services, modernising PKI, improving foundational network services, or addressing long-standing technical debt, our approach combines practical engineering with strong architectural oversight.

Alongside deep legacy capability, we bring extensive experience in modernising and transforming these services. This includes securing systems in situ, hardening environments to align with modern security expectations, and guiding transition strategies toward cloud and hybrid models. From incremental uplift to full replatforming, we help organisations modernise their foundations safely - ensuring legacy infrastructure becomes a strength rather than a constraint.
