Access Control

Access control decides who may enter which area and when — and documents it in a traceable way. It is therefore one of the most effective and at the same time most practical security measures, because it provides protection without hindering operations. We plan electronic access control systems per the DIN EN 60839-11 series, which superseded the former EN 50133.

A well-conceived access control considers the entire chain: identification media (from card and transponder to biometrics), readers, single-person passage devices, mantraps, authorization concepts and integration with higher-level systems. The choice of security level follows protection needs and risk — not every area needs the same depth, and we deploy multi-factor methods specifically where they are necessary.

The heart of it is the authorization concept. Authorizations follow the least-privilege principle: each person receives exactly the access their role requires — no more. Time profiles, zones and temporary authorizations for visitors and service providers are mapped cleanly, and all entries can be logged in an audit-proof manner. This creates not only security but also the demonstrability that audits and insurers expect.

The interplay of safety and law requires particular care. Log data is personal data and subject to the GDPR; we attend to purpose limitation, retention periods and co-determination. At the same time we design the system so that it releases escape and rescue routes in the event of fire — security and life safety must not contradict each other.

Access control is rarely an isolated measure. We integrate it with intrusion detection, video and control-room technology into a continuous security architecture, in which an unauthorized access attempt can automatically trigger video and alarm and be connected to the security control room.
